On June 12, 2014 a hail storm that hit Abilene produced more than $400 million in insured losses to vehicles, homes and commercial property. "This is the worst storm damage I've seen in my 41 years in the insurance business," Leroy Perkins of the Perkins Insurance Agency in Abilene, told the largest state insurance trade association in the United States. the storm, packing baseball-sized hail, moved directly south across Abilene pounding the city's north side and downtown area. Commercial buildings downtown received millions of dollars in damage to roofs, windows and structures. Total uninsured losses are also expected to be high, Perkins adds. "...

June 11, 2008 marks the tragic loss of 4 teenagers at a Boy Scout camp near Little Sioux, Iowa; 48 more were injured. The tragedy struck at the 1,800-acre camp about an hour north of downtown Omaha. An EF3 tornado, with 145 mph winds, descended on the remote camp, striking and leveling a cabin where campers had sought shelter as warnings of the storm circulated through the camp. A chimney at the cabin collapsed, sending heavy concrete blocks onto the Scouts. This was the worst of the storms that hit the Northern Plains that day. There were also two farms damaged from two different tornadoes...

Benjamin Franklin, inventor of bifocal glasses, the Franklin stove, one of those that wrote the Declaration of Independence and the Constitution, ambassador, Governor of Pennsylvania, on June 10 1752 in Philadelphia, flew a kite during a thunderstorm and collected an ambient electrical charge in a Leyden jar, enabling him to demonstrate the connection between lightning and electricity. According to the Franklin Institute, Franklin had been waiting for an opportunity like this. He wanted to demonstrate the electrical nature of lightning, and to do so, he needed a thunderstorm. He had his materials at the ready: a simple kite made with a large...

The tornado outbreak of 9 June 1984 is among the most important tornado events in Russia’s history because it was associated with substantial loss of life with 400 deaths, and contained one of two F4 tornadoes ever recorded for in that country. Very little information is available on a violent tornado outbreak that swept through areas north of Moscow in the summer of 1984. The Soviet Union had not yet disbanded and few details were leaked to the international media. The outbreak was the result of a series of violent supercell thunderstorms that travelled north-northeast at speeds greater than 50mph. Local newspapers re...

The 1953 Flint–Worcester tornado outbreak was a devastating tornado outbreak sequence spanning three days, two that featured tornadoes each causing at least 90 deaths—an F5 occurring in Flint, Michigan on June 8, 1953, and an F4 in Worcester, Massachusetts the next day. The Worcester storm stayed on the ground for nearly 90 minutes, traveling 48 miles across Central Massachusetts. In total, 94 people were killed, making it the 21st deadliest tornado in the history of the US. In addition to the fatalities, over 1,000 people were injured and 4,000 buildings were damaged. The tornado caused $52 million in damage, which translates to more than $350 milli...

On June 7 1984, nine people died and 200 were injured when a tornado slammed into the Iowa County, Wisconsin community of Barneveld. The F5 twister destroyed 90% of the town of 580 residents. What made Barneveld’s tornado rare is it hit overnight. A majority of tornadoes occur between 3 and 9 p.m., and violent tornadoes almost never happen late at night. Many tornadoes show a telltale “hook” shape on radar, but Barneveld’s tornado did not. Meteorologists could see fast-moving storms on radar heading northeast through Grant and Lafayette counties but without the hook, they did not know a tornado was forming. Most people in B...

Rainfall totals in the northeastern United States from January through the end of May 1925 had only reached half the normal total in most cities. This meant, at least for the first 5 months of the year the climate was more like patched central Texas than the lush and green landscape of the eastern seaboard. Heating of the lower atmosphere takes place when the ground is heated and transfers that heat to the air closest to the ground. When the ground is moist some of the sun’s energy goes into evaporating the moisture rather than heating the ground. When the ground is...

On June 4, 1976 a strong Tropical Cyclone, known in the US as a Hurricane, hit the port cities just north of Mumba on the west coast of India. In the decades prior to the storm, massive Tropical Cyclones has battered both the west and east coasts of India with huge waves and heavy rains resulting in massive flooding and tremendous loss of life. Along the Indian east coast, especially in the northern part of the Bay of Bengal, the area is flat, almost at sea level for hundreds of square miles and ocean water is often pushed far inland because of...

What started out as just another day in June in Colorado in 1921, rapidly turned into one that would never be forgotten in the town of Pueblo, Colorado. A cloudburst enveloped the town the afternoon of June 3, 1921. During a typical cloudburst, over half an inch of rain may fall in a matter of minutes, and that is exactly what happened in Pueblo, creating devastating consequences for the heart of the town where the Arkansas River and Fountain Creek meet. At about the same time the rains were drenching the downtown area, there was another downpour about 30 miles north over Fountain Creek...

On June 2, 1889, the same heavy rains caused that had helped cause massive flooding in Johnstown, Pennsylvania, overwhelmed the South Fork Dam several days before, hit the Washington, DC, area. Most of the roads in DC at the time where unpaved and unlike some other major cities of the time not even covered in cobblestones, their surface consisted mainly of dirt. As a result, when the Potomac River flooded and areas around Pennsylvania Avenue and the White House the whole region was under several feet of water the flooding was made worse by sewers that became clogged with dirt from unpaved...

The World Health Organization reports that nation of Bangladesh is especially vulnerable to tropical cyclones, known as hurricanes near the United States, because of its location at the triangular shaped head of the Bay of Bengal, the sea-level geography of its coastal area, its high population density and the lack of coastal protection systems. During the pre-monsoon season in April and May or post-monsoon season in October and November, cyclones frequently hit the coastal regions of Bangladesh. About 40% of the total global storm surges are recorded in Bangladesh, and the deadliest cyclones in the past 50 years, in terms of...

Johnstown, Pennsylvania, lies hard against the Conemaugh River in its deep valley in the western part of the state. Founded in 1770, it grew quickly as the Civil War approached, fortunes were made in iron, coal and steel. By 1860, the Cambria Iron Company of Johnstown was the leading steel producer in the United States, outproducing steel giants in Pittsburgh and Cleveland. After the war it became the center of America’s growing industrial might and the site of many struggles by workers for recognition. High above the city, the Commonwealth of Pennsylvania built a dam between 1838 and 1853, as part of a cr...

On May 30, 1879 the town of Irving, Kansas in the northeastern part of the state was a growing farm community with several hundred residents. Today, though Irving is a ghost town. On May 30, 1879, two tornados destroyed most of the town, leaving 19 dead and many more injured. Some residents left Irving, but the town was rebuilt, and new businesses arrived, allowing Irving to regain its prominence as a local agricultural center. During the summer of 1903, the Big Blue River flooded and destroyed homes, crops and bridges. The river threatened to do it again in 1908 but the townspeople were prepared and were able...

From 1900 until 1914 almost 100,000 passengers in ocean liners, crossed the Atlantic to Canada, mainly from Great Britain. The main port of entry and embarkation to and from Canada was Quebec City, on the St Lawrence River. Many of the ocean-going passenger ship were huge, not quite rivaling the Titanic, but able to transport almost 1,500 passengers back and forth across the Atlantic. On the morning of May 29, 1914, a thick river fog formed quickly on the surface of the St Lawrence and extending almost 100 feet in the air. River fog can form when the sun heats the air just above the surface...

Brackettville, the county seat of Kinney County in Texas, is on U.S. Highway 90 twenty-two miles northeast of the Rio Grande and 125 miles west of San Antonio. It is named after Oscar Brackett, who established the first general dry goods store near the site of Forth Clark in 1852. Brackett, as it was called originally, was established on the San Antonio-El Paso Road, and by 1857 its Sargent Hotel and small restaurant were a regular stop for the San Antonio-San Diego stage line. The Texas State Historical Association reports that the community experienced a period of steady growth after the Civil War...

In 1896 St. Louis was listed as the 5th largest city in the United States, trailing only New York, Chicago, Philadelphia and what was then the separate city of Brooklyn. More than half a million people lived there on the banks of the Mississippi River. The morning of May 27, 1896 dawned calm and steamy and belied what was coming that afternoon. One of the greatest natural disasters to strike one of the largest US cities was awaiting residents in the afternoon. In what remains the third most deadly tornado in U.S. history struck St. Louis, on the afternoon of May 27, 1896. According t...

The term Pneumonia front, first coined by Milwaukee Weather Bureau Office in the 1960s,  is used to describe a rare meteorological phenomenon observed on the western Lake Michigan shoreline during the warm season. These fronts are defined as lake-modified small scale cold fronts that result in one-hour temperature drops of 16 °F or greater.  They do not necessarily have to be large scale, cold fronts to bring weather changes to an entire region. Very often in the spring to early summer the temperature difference between the cold lake waters and the warmer air over land can be as much as 35–40 °F . Under weak...

The number of people killed by lightning in recent years is a far cry from annual lightning deaths decades ago. In the 1940s, for instance, hundreds of people were killed each year by lightning. In 1943 alone, 432 people died. The sharp drop in lightning deaths over the past 75 years " coincides with a shift in population from rural to urban regions," wrote meteorologist Ronald Holle in an article in the Journal of Applied Meteorology. In the 1940s, "there were many, many more small farmers who were out working in fields," which meant many more chances to be struck by lightning. In add...

Another Spring Day and another round of wild weather in the state of Texas. Severe weather is most prevalent in Texas in the Spring and May 24, 1986 was no different, severe thunderstorms blasted the area. Damage was heaviest from just north of Downtown Fort Worth and across the east side of town to southwest of Arlington where a roof collapsed over portions of a bowling alley injuring seven people. Windows were blown in with roof damage at motel across the street. Hail as large as golf balls blew in drifts two feet deep in spots. 3-5“ of rain fell in one ho...

By May 23, 1908 4-8" of rain fallen across much of northern and central Texas in the preceding days on already saturated land especially on the upper Trinity and Brazos River Basins. The rise in the rivers continued for several days toward the end of the month. Large crowds of onlookers gathered on bridges all over Texas the view the unusual site of rising rivers. Most times the rivers were almost dry trickles or brief raging white water torrents spurred on by brief cloudbursts from thunderstorms. But the days and days of steady rains in the part of the state brought...

The May 1957 tornado outbreak took place across the US Central Plains from May 19 to May 21, 1957. An F5 tornado, the strongest on the tornado intensity scale, on May 21 was the most significant in the outbreak and is known as the the Ruskin Heights Tornado where the area where the worst of the damage occurred, a suburb and housing development south of Kansas City. 57 tornadoes were reported from Colorado to the Mississippi Valley and 59 people were killed during the outbreak. But in the Kansas City area and specifically Ruskin Heights the impact was devastating. The Kansas City Star reported in its story f...

Extreme heat can be rather uncomfortable. But what actually happens to the human body as the mercury rises? On humid days, when the air is already saturated with water, sweat evaporates more slowly. This explains why it feels so much hotter in high humidity. When relative humidity reaches a high enough level, the body's natural cooling system simply can't work. Sweat evaporates very slowly, if at all, and the body heats up. According to the Mayo Clinic, the most serious level of this breakdown is heat stroke, and it occurs when the body’s temperature reaches an excess of 104 degrees Fa...

Ever since people have traveled the Great Lakes, storms have sunk ships and taken lives. In fact, the very first recorded sailing vessel on the upper lakes, was lost in 1679. Since that time, massive and historical storms have swept the lakes, most numerous in the month of November. With the coming of modern technology and stronger vessels, fewer such losses have occurred. The large surface of the lakes allows waves to build to giant heights out in the open. Strong winds can cause storm surges that lower lake levels several feet on one side while raising it even higher...

The state of Maine is known for many things, including my favorite, Maine lobsters. But one of the longest running industries in North America, dating back until the early 1600s is logging. The British Royal Navy quickly claimed the best stands of light and strong Eastern White Pine for the masts, spars, and planking for their fast and maneuverable ships. England's competitors, the French, the Dutch, and the Spanish, were left to build from the heavier Baltic Fir. It was Revolutionary War debt which boosted the first large scale harvests. To raise money, Massachusetts sold land to the District of...

In 1865, a group of mill owners from the Northampton area of Massachusetts constructed a dam on the Mill River north of the town of Williamsburg, it was constructed by using a design drawn by one of the owners, a man with no training in engineering. The dam was poorly constructed and leaked as soon as it was filled, still it was in place for 9 years. But on May 16, 1874 after several days of heavy rain, the dam completely failed. Almost all off of the water held behind the earthen dam burst out like a wall of water. 139 people died in the to...

During the late afternoon and early evening of May 15, 1968, five tornadoes, two F1s, one F2, and two F5s occurred in Iowa. These tornadoes were part of the May 15-16, 1968 outbreak with a total of 39 tornadoes which affected ten states; Arkansas, Illinois, Indiana, Iowa, Kansas, Minnesota, Mississippi, Missouri, Ohio, and Tennessee. The tornadoes in Iowa caused 18 fatalities and 619 injuries of which 450 occurred in Charles City alone. The huge tornado, approximately a half mile wide passed directly through Charles City from south to north. The tornado destroyed, 372 homes and 58 businesses, 188 homes and 90 businesses sustained major damage, and 356 homes and 46 businesses s...

Late season snowstorms, like those in the autumn can cause havoc in a different way than those in the middle of winter. Many trees in both seasons are in full or partial leaf, as are bushes and other shrubby. In the middle of winter, snow’s greatest impact is on the inability to travel due to impassible roads or severe drifting that blocks doorways and even makes walking difficult. In the fall and spring, because of more sunlight it is hard for the snow to accumulate on the warmer streets and sidewalks so that usually isn’t much of a pr...

Hailstorms are notorious for inflicting costly damage upon property and crops every year in the United States. Annually, the destruction from these frozen rain pellets that travel dozens of miles per hour through the atmosphere results in $1 billion in damage, according to the National Oceanic Atmospheric Administration – NOAA. Hail also poses a safety threat to both humans and animals. NOAA estimates that 24 people in the U.S. are injured each year, with some injuries significant enough to land them in the hospital. In May , 1995, severe storms brewing over the Dallas-Fort Worth metro-plex in Texas produced damaging winds, heavy rain an...

Newspapers and radio stations East of the Mississippi on the morning of May 12, 1934 carried ominous messages and headlines of a thickening black cloud of chocking dust and dirt moving out of the Great Plains states. The cloud would envelope the Mid-west and then Eastern states on May 12, turning mid-day sunlight into an eerie darkness, that seemed like night in many major cities. What happened? Actually, the causes can be traced back decades. Favorable weather conditions in the from 1900 to the 1920s with significant rainfall and relatively moderate winters, encouraged increased population and farming in the Great Plains. But the region...

The first week of May in 2003 had one of the worst tornado outbreaks on record in the United States reports indicate that 384 tornadoes occurred in 25 states, causing 42 deaths with at least 23 tornadoes on each day. Hardest hit were Missouri, where tornadoes occurred on 6 of the 7 days and 19 died; and Tennessee, where tornadoes occurred on 5 days and 11 died during the week-long outbreak that ended on May 11, 2003. The outbreak was so important that an entire paper was published on it in the American Meteorological Society magazine. There were also an incredible 723 wind reports and 1,782 hail reports that week! Oklahoma City suffered multiple...

May of 1889 was particularly warm and humid across the eastern United States. The jet-stream that steers weather system had lifted far north into Canada and air from the steam Gulf of Mexico has surged northward into the void. By May 9th chilly weather has re-established itself across the mid-west and was heading eastward as the jet stream dipped southward to push the chilly weather along. As the cold front marking the leading edge of the change moved into the east on the afternoon of May10, 1889 a rash of violent thunderstorms erupted and brought extensive damage to a corridor in Pennsylvania t...

One of the most powerful May snowstorms to strike the Northeast hit on May 9, 1977. 13" fell at Gardiner, MA; 12.7" at Worchester, MA; 1/2 million people lost power. Officially 1/2" in Boston, but thunderstorms with snow in the suburbs dumped 10" in the Wellesley area. A foot of snow fell at Foster, RI. Bare grass did not reappear in Wellesley, MA until the afternoon of the 11th and it was the heaviest snow of the entire winter there...all the plows were activated although in many cases the plows had already been removed for the season from the trucks...schools were closed in the western...

The hundred Years War between England and France began in 1337; by 1359, King Edward III of England led a huge army across the English Channel to France. The French did not engage in any pitched battles and mainly stayed behind protective walls of towns and cities. Meanwhile Edward conquered the countryside. In April 1360, Edward’s forces reached the Paris suburbs and began to move toward Chartres and its famous cathedral. While they were camped outside the town, now a suburb of Paris, in early May, a sudden storm hit. Lightning struck, killing a number of people, then large hailstones began falling hi...

Natchez, Mississippi was a bustling and booming river town hard against the Mississippi River in 1840, it was 20 years after Mississippi joined the union and 20 years before the Civil War. But on May 7, 1840 the second deadliest tornado in U S history struck the city. A large and powerful tornado went right through the center of town, flattening most of the buildings. But even worse was the damage on the Mississippi River, which was filled with boats, including 120 flatboats and steamboats carrying people and goods along the main transport system in the part of the nation – the Mississippi River. The powerful tornado wreck...

The airship Hindenburg, the largest dirigible ever built and the pride of Nazi Germany, bursts into flames upon touching its mooring mast in Lakehurst, New Jersey, killing 36 passengers and crewmembers on May 6, 1937. After opening its 1937 season by completing a single round-trip passage to, Brazil earlier in the year, in late March, the Hindenburg departed from, Germany on the evening of May 3, on the first of 10 planned round trips between Europe and the United States that were scheduled for its second year of commercial service. Except for strong headwinds that slowed its progress, the Atlantic crossing of the Hindenburg was otherwise un...

The office of the Town Clerk is the repository for the maintenance and safekeeping of records for the Town of Ashford, Conn. The Town reports that housed in the fire-proof vault in the office of the Town Clerk are all land records, Town Meeting minutes, Town Ordinances, birth/marriage/civil union/death records, land surveys, election records, trade names, liquor permits, contracts, town reports, veterans discharge filings, Town board/commission/agency agendas and minutes, listings of Notaries Public, Justices of the Peace, election records, and other historical documents. Just about everything and anything you can think of. In addition to...

The neighborhood of Germantown in Philadelphia sits at a higher elevation than most of the rest of the city. From 250-300 feet above sea level the temperature can average a degree or two colder than the city below. During weather situations that are borderline between rain and snow, often times much of the City of Philadelphia will have a slushy mixture of rain and snow, while only wet snow falls in Germantown and its adjacent elevated neighborhood of Chestnut Hill; sometimes depositing a couple inches of snow. On May 4, 1774 Germantown was a not part of the City of Philadelphia yet...

Most of New Orleans, Louisiana is below the flowing water level of the Mississippi River, that also means that the city is below sea level and so both the Gulf of Mexico and Lake Pontchartrain surfaces are also above the ground level of the city. Because of that, the city does not have a natural drainage for rainwater, so pumps are required to remove rainwater from the region. On May 3, 1979 the pumping drainage system had been in operation since 1900. That system was designed to handle one inch of rain per hour for the first three hours, and one-half inch...

Twelve people were hospitalized Saturday May 2, 2009 after the roof of the Dallas Cowboys' indoor practice facility in Frisco, Texas collapsed during a thunderstorm. The giant blue Cowboys star atop the building lay crumpled on the ground. The storm knocked out power at team headquarters and splintered trees across the property. The roof was a large air- and tension-supported canopy with aluminum frames covering a regulation 100-yard football field. Approximately 70 players, coaches, staff and media were reported inside. Some of the injuries were serious, but none were considered life-threatening. Based on the national standards for determining loads and for designing structural st...

The winter of 1853-1854 had been a particularly snowy one across the mountains of Vermont and New Hampshire. Not record breaking, but it was a cold winter and the snows that fell during the winter months didn’t melt much. The cold lingered into April and so did the snow on the ground. The weather pattern broke as the month ended, winds in the high atmosphere turned from the northwest to out of the south and ushered in warm air that had been building across the Gulf states in the early spring. At the same time copious volumes of moisture we...

The Huang He (Wang He) or Yellow River is one of the longest rivers in China, at 3,398 miles, it loops northward from the mountains in western China, then flows east, each year bringing 1.6 billion tons of fine-grained silt from the mountains to the huge flat basin of the north China plains. That rich laden dirt and silt makes the region one of the most fertile in the world, it is China’s breadbasket. The silt nourishes and replenishes the land. The Yellow River gets its name from its rich, fine-ground, golden mud. Unfortunately for the farmers, the only way the ri...

On April 22, 1991 an area of tropical thunderstorms began to organize in the Bay of Bengal it would grow to become one of the deadliest tropical cyclones ever recorded. The storm hit, one of the most populated areas in Bangladesh. An estimated 200,000 people were killed by the storm, as many as 10 million people lost their homes, and overall property damage was in the billions of dollars. Once the weather system organized it began moving north. By April 24 the storm was designated Tropical Storm 02B, and by April 28 it was a tropical cyclone, or as they are known in the western hemisphere...

A hailstone begins as a water droplet that is swept upward by an updraft inside of a thundercloud. Inside the cloud, there are a large number of other supercooled water droplets already present. These supercooled particles will adhere to the water droplet’s surface, forming layers of ice around it. The size the hailstone reaches depends on the amount of time it spends surrounded by supercooled water droplets, but eventually gravity causes the stone to fall to the Earth. As gravity takes over, they will fall to Earth at approximately 106 miles per hour. The exact velocity each stone falls at...

Santa Ana Winds occur when air from an area of high pressure over the dry, desert region of the southwestern U.S. flows westward in its clockwise circulation toward the California coast. This creates dry winds that flow east to west through the mountain passages in Southern California. These winds are most common during the cooler months of the year, occurring from September through May. Santa Ana winds typically feel warm or even hot because as the cool desert air moves down the side of the mountain, it is compressed, and that causes the temperature of the air to r...

The Chernobyl, Russia nuclear disaster was the worst nuclear disaster in history and occurred at the Chernobyl Nuclear Reactor Plant. A catastrophic eruption ripped through the power plant on April 26, 1986, spewing radioactive particles into the sky. The deadly blast was caused by the explosion of the RBMK reactor number 4, a result of human error and faulty equipment. More than 50,000 people from the nearby town of Pripyat were evacuated following the blast. But plumes of deadly radioactive matter were sent high into the atmosphere as the uranium core lay exposed in the days that followed. The particles were swept across Europe...

Most lightning strikes occur from cloud to cloud – but about 20% go from clouds to the ground. Lightening striking the ground has caused problems with pipes and water supplies.. Some people have also experienced cloudy or discolored water after a lightning storm. Due to the strike, the vibration into the earth can shake a ground water well causing any built-up minerals to fall into the water supply. When lightning strikes near a home or other structure, sending electricity shooting through the ground, the electricity, which prefers to flow through metal rather than dirt, seeks out any buried copper pipes or the ho...

A large tornado slammed into a section of I-44 east of Tulsa during the early evening hours of April 24 1993. The Washington Post reported that the storm blew cars and trucks off the interstate highway and damaged dozens of homes that evening, killing at least 10 people, injuring at least 50 and leaving hundreds homeless. "This was not a storm that stayed down and then went back up. It stayed down for several minutes and totaled the area," said Jerry Griffin, an inspector for the Tulsa County Sheriff's Department. That area was about a mile wide and two miles long, he said. At...

April 23, 2013 was more than a month deep into the Spring, but Old Man winter wasn’t quite done with depositing a new round of cold weather into the Great Plains. The weather during the middle of April in the mid-section of America had been mild, field work had already gotten underway. But far to the north across the arctic lands of Canada cold weather had been building for more than week. At the start of the third week of April it was unleashed southward, bringing a cold wave more typical of mid-winter. On April 23, 2013 all across Montana, Wyoming and North Da...

1980 brought the United States one of the worst heat waves in its history. The intense heat and drought wreaked havoc on much of the Midwestern states and Southern plains throughout the summer of 1980. It is among the most devastating natural disasters in terms of deaths and destruction in U.S. history, claiming at least 1,700 lives and because of the massive drought, agricultural damage reached $20 billion or almost $65 billion in 2022 dollars. The heat wave began in June when a strong high-pressure area began to build in the central and southern United States allowing temperatures to soar to 90 degrees almost every day fr...

Dust devils, are small, brief whirlwinds occurring most frequently in the early afternoon when a land surface is heating rapidly. Dust devils are occasionally made visible by the lofting of dust, leaves, or other loose matter from the ground. Dust devils form when a pocket of hot air near the ground rises quickly through cooler air above it, forming an updraft. If conditions are just right, the updraft may begin to rotate. As the air rapidly rises, the column of hot air is stretched vertically, which causes intensification of the spinning effect. Most dust devils are usually small and...

Strong temperature contrasts and violent weather outcomes in the springtime in the United States are generally unique in the world. Vast flat-lands that start as in the great coastal areas of Texas and Louisiana gently roll northwest from there into the Great Plains on the central United States and extend up into Canada. Weather systems can traverse the region unencumbered by mountains or large bodies of water. In the spring cold air is still left over from the departing winter, lurking in northwest Canada, in the Yukon. Meanwhile heat from the coming summer is building across Mexico and even Arizona...

In the early morning hours of April 19, 1775, Paul Revere was making a mad dash through Middlesex County just west of Boston. He was trying to avoid British patrols but was stopped by one briefly before making his getaway, the roads were soft and muddy from the heavy rains of the previous day and he was able to elude his captors. It was not last time the weather would play a part in that fateful day. Revere galloped from town to town, from farm to farm to warn that the British regulars were coming to seize the stores of powder and...

Those are the opening lines of the immortal poem, “Paul Revere’s Ride”, by Henry Wadsworth Longfellow. It was one of my father’s favorite poems and  Those are the opening lines of immortal poem, “Paul Revere’s Ride”, by Henry Wadsworth Longfellow. It was one of my father’s favorite poems and because of that I memorized it when I was 7 years old. Revere’s task was to ride through the countryside and call out the country-folk to arms to resist British tyranny. As the poem said, Revere was across Boston Harbor in Charlestown to watch the steeple of the Old North Chur...

Boston, Massachusetts averages just under 2” of snow for the month of April. Given is proximity to the Atlantic Ocean and the warming effects of the water, big snowstorms in April are uncommon – but not rare. On April 17, 1821 such an uncommon event occurred as a strong storm system slowly lumbered up the eastern seaboard. Cold air held sway over New England, the storm swung northward but was far enough out to sea to prevent the warming effects of a flow of air off the ocean. The big counter-clockwise swirl of winds around the system blew from the north northeast and off...

On April 16th, 1851, a strong nor'easter smashed into Cape Cod, and brought the highest waters ever seen in that area up to that the time, easily besting the high tides of 1723. The system went into the history books as "The Lighthouse Storm.” Heavy gales and high seas pounded the coasts of New Hampshire and Massachusetts. The storm arrived at the time of a full moon, and the high tide was already well above what would be termed normal for the coast. That evening, the newly-constructed Minot's Ledge Lighthouse was destroyed by this massive storm. The storm weakened the tower's iron supp...

1912 was a year of promise. The start of World War I was still two years away and science and technology were ascendant, with the outlook that humans had finally conquered nature, and their inventions could overcome anything. Albert Einstein had already been working on his theories around relativity that would revolutionize Physics. In practical terms, the first decade to the 20th century saw the invention of the vacuum cleaner, the air conditioner and the electric washing machine. It seemed like science was triumphant. It was with that attitude that British White Star Line commissioned the building of the largest ship e...

The National Weather Service reports that Hail is a form of precipitation consisting of solid ice that forms inside thunderstorm updrafts. Hail can damage aircraft, homes and cars, and can be deadly to livestock and people. Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze. Hailstones then grow by colliding with liquid water drops that freeze onto the hailstone’s surface. Hail falls when it becomes heavy enough to overcome the strength of the thunderstorm updraft and is pulled toward the earth by gravity. Although Florida has the most th...

The New York Times reports that chatting on the telephone connected to a land-line during a thunderstorm can electrocute you, it is no urban legend. A bolt of lightning that strikes a telephone line can cause an electrical surge to shoot through the wires and enter a handset. The odds of this are relatively small, and most phone companies have protective measures in place. Still, the risk exists, and the National Oceanic and Atmospheric Administration recommends that people avoid using telephones and other appliances during electrical storms. Cases of customers' being jolted while on the phone in a storm are...

The average annual snowfall in Philadelphia is slightly more than 22”. In April, Philly averages a half an inch of snow and there is measurable snow in April there only once every other year. 1841 was not so kind to Philadelphia. Unusual late season cold lingered for much of the month and a series of storms swept out of the Gulf of Mexico and up the East Coast of the United States bringing one snow event after the other. 6” of snow fell in the city on April 10th  and 3” fell on Aril 13 and 14th, but the heaviest snowfall occurred in between those tw...

On April 11, 1999 more than 3” of rain fell in Hong Kong during a cloudburst as heavy thunderstorms pounded the region. Streets were flooded and stores were forced to shut. The 3” of rain was more than Hong Kong had received in the first 3 months of 1999. As it turns out that is only half as much rain as is normal in Hong Kong from January to March when more than 6” is normal – still not a huge amount of rain. But rainfall is abundant, in Hong Kong when looked at through the lens of a full year. In fact, the normal yearly rainfall is aroun...

The winter of 1995-1996 in the Northern part of the United State just didn’t seem to want to end. Cold air lingered on well past the start of Spring. April was cold in that region of the country, especially New England and the first half of the month seemed more like winter than Spring. At the start of the second week of April temperatures were below freezing most nights and even during the daytime, readings had a tough time reaching 40. Meanwhile a strong storm was organizing off the coast of South Carolina and started to make its way up...

Tornadoes have been recorded on all continents except Antarctica. The United States has the most tornadoes of any country, as well as the strongest and most violent tornadoes. A large portion of these tornadoes form in an area of the central United States. Canada experiences the second most tornadoes in the world. Other areas of the globe that have frequent tornadoes include significant portions of Europe, South Africa, Philippines, Bangladesh, parts of Argentina, Uruguay, and southern and southeast Brazil, along with northern Mexico, New Zealand, and far eastern Asia. Bangladesh and the eastern parts of India are very exposed to...

In the early days of April 1938 arctic cold that had been building and was bottled up in Alaska and the Yukon came crashing southward along the east slopes of the Rocky Mountains. The wintry chill reached cities like Cheyenne and Denver, Colorado Springs and Pueblo and then smashed eastward enveloping Omaha, Wichita and Amarillo. The cold modified as it headed eastward but held firm for several days from Montana to New Mexico and eastward into Nebraska, Kansas and the Oklahoma and Texas panhandles. Meanwhile off the coast of southern California a storm was brewing. That system headed eastward and spread...

April 7, 1977 marked the first home game in the history of the Toronto Blue Jays. Actually, for a while, in February 1976 , it looked as if the National League’s San Francisco Giants would move to Toronto, where there were buyers eager for the club. When the Giants were sold in March 1976 to new owners determined to keep them in San Francisco, the American League jumped in to establish Toronto as an American League city, setting up an expansion club, and announced the Blue Jays, who began play the next year. Despite being one of the northernmost cities with a baseball team. The...

April 6, 1936 , brought one of the worst weather-related disasters in Georgia history. A series of strong tornadoes struck the southern United States but none was deadlier than the one that struck Gainesville, Georgia on April 6 1936. It was part of a devastating outbreak of 17 tornadoes across the South. And it wasn’t the first for Gainesville - another tornado killed more than 100 people in January 1903. In 1936, not one, but two tornadoes tore through the heart of town, destroying much of the business district and the county courthouse, trapping hundreds in debris. The funnel fueled fires all over the area, including the Cooper Pa...

The summer of 1816 was not like any summer people could remember. The National Center for Atmospheric Research reported that, snow fell in New England and gloomy, cold rains fell throughout Europe. It was cold and stormy and dark. 1816 became known in Europe and North America as “The Year Without a Summer.” The year before on April 5, 1815, Mount Tambora, a volcano, started to rumble with activity. Over the following four months the volcano exploded - the largest volcanic explosion in recorded history. Many people close to the volcano lost their lives in the event. Tambora ejected so much ash and dust into...

In the 1930s, lighter than air ships, or dirigibles where the rage for long distance flight. Trans-ocean flight by airplanes was virtually impossible, especially as a passenger service. Planes would have to hop and skip from one re-fueling station to another across the north Atlantic. Long distance non-stop flight was still a way off not coming into practical availability until well after world War II. So, the big balloons where the rage. Many of them would ultimately meet with disaster including the US Shenandoah and the famous explosion and crash of the German air ship, Hindenburg in Lakehurst New Jersey...

The last few days of March 1974 and the first couple of days of April 1974 brought unseasonable warmth to much of the nation east of the Mississippi River. Across Ohio and northern Kentucky, the daffodils were blooming, and grass had turned a bright green, and, in some places, there was a hint of blue, that marks many types of grasses in Kentucky. Birds had already started to build their nests as the unseasonable warmth lasted for several days. But it was a false sign of spring and trouble was brewing in the vast frozen hinterlands of arctic Canada. Bitter cold...

The city of St. Louis, Missouri, is known as the “Gateway to the West.” It has this nickname because it was the starting point for the westward movement of people in the United States during the early to mid-1800s. It was a traveling hub for many settlers, hunters and others migrating west. The Gateway Arch now in St. Louis symbolizes the city’s nickname. St. Louis was where many wagon trains got organized that first began to head west on the Oregon Trail and to California. Even though Kansas City and Independence Missouri where other jumping off points, St. Louis...

April snowfalls in the northeastern section of the United States are not unusual, but heavy snowfalls are rare. April snowfall totals average less than 5% of the season average in places like Boston. In fact, the normal snowfall in the month of April in Boston is less than 2”. In 1997 what would go into the books at the Great April Fools Day Snowstorm blasted up the East Coast. Cold air was already firmly in place across the region and this system pounded New England on April 1, 1997. 25.4” of snow fell at Boston’s Logan Airport, and broke the all-time 24-hour snowfall record of 23.6" set 1n...

One of the earliest chronicled winter storms to strike upstate New York after the Revolution, was the strong system that impacted the region on March 31, 1807. The Herald in Cooperstown , NY reported, and I quote “The wind roared in the forests similar to the sound of the great cataract, the air was alternately filled with snow and transient gleams from the sun.” Along the Atlantic coast high winds and rain was the scene in New York Harbor, The New York Post described the situation. From it’s pages it said: “Amidst the bustle along the ports, in securing vessels and getting...

In the 1820’s and 1830s just after Maine became a state, after separating from Massachusetts, crop failures combined with cold weather caused some in New England to dream of warmer climates to the west. About this time Newspaperman Horace Greely was purported to have said “Go west, young man, and grow up with the country”? Many started the exodus for the Midwest. A major cradle of Midwestern settlement was Maine, Maine’s stony soil and the decline of its shipping trade pushed thousands of Mainers to get out just after it achieved statehood in 1820. The exodus was so bad that many...

According to the National Oceanographic and Atmospheric Administration, ice jams on bodies of water are caused by melting snow and ice in the springtime. Warm temperatures and spring rains cause snow and ice to melt very rapidly. All this extra water causes frozen rivers and streams to swell up, and the layer of ice on top of the river begins to break up. The rushing river carries large chunks of ice downstream, and sometimes a group of ice chunks get stuck in a narrow passage of a river or stream. The ice chunks form an ice jam or ice dam...

A strong storm developed in the southeastern United States on the 27th of March 2005 and grew even more dangerous as it moved up the East Coast on March 28th before moving out to sea off the New England Coast. Heavy rain fell across the Philadelphia and New York City metropolitan areas on the 28th and set the stage for a one-two punch of flooding when a second storm arrived in early April. Poor drainage and urban flooding resulted from the storm on the 28th and some rivers also experienced flooding, especially in New Jersey, notably along the Passaic and Ramapo Rive...

The prairies and plains of west central Canada, like those on the plains of the central United States are subject to wide swings of weather. Geographic barriers like mountains and large bodies of water can block or deflect even large-scale weather systems. Ocean temperatures and currents impact the track of storms. The influence of abnormally warm or cold waters, known as El Nino and La Nina, off the west coast of the Americas results in abnormal snow and rainfall patterns across much of the North American continent. Sometimes, as slow-moving storms come toward ocean shorelines, those storms almost bounce a...

Late season Nor’easters in March are often times the most powerful storms to strike the northeast. On March 26, 2014 one such storm struck New England. The strong late season winter storm brought howling winds and heavy snow to Cape Cod, Nantucket and Martha’s Vineyard. Winds gusted as high as 82 mph on Nantucket, and more than 100 mph just off shore. The wind drove snow against buildings and homes plastering doors shut. Drifts of snow several feet high impeded emergency vehicles from removing trees and power poles brought down by the hurricane force winds. Most of the major cities in New Engl...

Tornado Alley is that area in the United States that has more tornados than anywhere else in the world. Stretching from central Texas to Eastern South Dakota. Tornados are more likely in Texas and Oklahoma in the Spring, and then they are more numerous in the northern plains in the summertime. Fed by the contrast between moist air from the Gulf of Mexico and super dry air that blows down off the Rockies, and the contrast in temperatures between the ground surface and midlevels in the atmosphere, severe weather development is primed. This is most common in Tornado Alley, and...

It had been fairly snowy across Kansas and Missouri in the 1911-1912 winter season. By the later stages of March, Kansas City already had recorded more than 40” of snow including 15” earlier in March alone. Average snowfall for an entire season is about 15” so the city already had well above its normal snowfall. Milder weather had made several attempts to move into that part of the nation during March, but cold air held firm and so it was cold on March 23, 1912 as a storm spun up in the southern Rockies. That’s system moved eastward pulling moisture from the Gulf of Mexico ahe...

On March 23, 1913 the rain started falling across the Mid-west and it didn’t stop for 4 days and 4 nights. The deluge resulted in epic flooding unequaled in American history before and after. Known as the Great Flood. The storm system that produced the flood in late March 1913 began with a typical winter storm pattern, but developed characteristics that promoted heavy rain and at times sleet and snow. As the storm gained strength on Sunday, March 23, high winds, hail, sleet, and tornadoes settled in across a vast swath of the nation’s mid-section. Major tornadoes hit Omaha, Nebraska where 94 died; also hit wer...

The winter of 1935-1936 was a severe one with lower than normal temperatures in the eastern half of the United States. As of early March, it was estimated that the snowpack in Northern New England contained an average of about 7.5 inches of water – the equivalent of almost 100” of snow. Deep snow also covered the ground across Ohio, Pennsylvania and New York state. Early in March 1936, a warm, moisture-laden storm moved into the area from the Ohio Valley to New England and stalled producing heavy rainfall. As the snow started to melt and the rains fell, streams and rivers began to fill...

March 1868 started out relatively mild across the Eastern states. The winter of 1867-1868 had been a uniformly cold winter. Life was finally starting to get back to normal in the aftermath of the Civil War in the Northeastern states and the break in the winter, early in March was welcomed as the harbinger of an early spring. In the middle of the month though, a storm took form across the nation’s midsection and as it rolled eastward arctic air moved out of western Canada, across the Great Lakes into the Northeast. With cold weather firmly in place the storm mo...

Often times wave patterns develop in the high atmosphere, the strongest winds in these waves are represented by the jet stream. These waves in the air, like waves in the ocean, have high and low points over time and space. From a geographical perspective the high point usually supports high pressure and the low points low pressure or storms. On the western side of the high pressure or ridging it’s usually warm and winds blow from the south, close to the center of the low point or trough of the wave there is storminess. When patterns like this de...

On March 19, 1958. Rain began falling along the eastern seaboard as a weak storm moved across the Ohio Valley. As that system approached the East Coast cold air was drawn into the storm from eastern Canada. The storm exploded. As it strengthened rapidly and the cold air was pulled southward all the way into the Mid-Atlantic states, the rain changed to snow and more and more moisture was fed into the system from a strong jet stream that reached all the way down into the Gulf of Mexico. When the rain started in March 19th temperatures were well up into the 40s...

Early spring often brings the most violent weather to the nation’s midsection of the entire year. High in the atmosphere, up where the jet stream is, temperatures can still be almost as cold as they are in mid-winter, yet down on the ground temperatures can soar to at times close to summer-time levels. The extreme temperature contrast, that occurs at no other time of the year, combined with turning winds from the surface up into higher levels of the air leads to the formation of severe thunderstorms and multiple tornados. On March 18, 1925 perhaps the greatest severe weather event in th...

The first shots of the Revolutionary War were fired in the towns of Lexington and Concord just west of Boston in April 1775. What started as a British victory as they looked for munitions stored by local militia turned into a rout as American militia from all of New England converged on the area and drove the British back into Boston. The British attempted to break out of Boston at the Battle of Bunker Hill some months later and even though they won because the Americans ran out of ammunition, the victory came at a terrible cost of dead and wounded...

On March 16, 1843 one the first winter storms to be documented to sweep out of the Gulf and Mexico and impact must of the eastern part of the nation was observed. At the start of the second week of March in 1843 arctic air moved southward out of the vast snowfields of the Yukon, down the east slopes of the Rockies and then spread eastward to the Atlantic seaboard. The cold air held for the next few days and on its southern flank, well south in the Gulf of Mexico a storm started to organize. That system strengthened rapidly and then...

The 1930s were not kind to the Great Plains, in the midst of economic disaster caused by the Great Depression, one of the most prolonged periods of severe weather struct the region in the form of severe drought, known as the Dust Bowl. Mass migration hit the area and many parts of the region lost population that would not be replenished for more than 25 years. With insufficient understanding of the ecology of the plains, farmers had conducted extensive deep plowing of the virgin topsoil of the Great Plains during the previous decade; this had displaced the native, deep-rooted grasses that nor...

The term blizzard has found a significant spot in our language. A blizzard is officially defined as a storm with "considerable falling or blowing snow" and winds in excess of 35 mph with visibilities of less than 1/4 mile for at least 3 hours. The term has been applied to many snowstorms in American history, most notably the Blizzard of ’88. The term has also been used for snow events that did not meet the criteria – but where big snowstorms none the less. But the term wasn’t even invented until March 14 1870. The Editor of the Dakota Republican of Vermillion South Dakota described the stor...

Records show that early settlers to what would become the Mid-Atlantic and New England states report of huge snowstorms dating back to the 1600s. Native American tales tell of deep snow and powerful winds from well before that time in the region. But modern city life and dense population was not yet established. By the 1880s though the population of Northeast cites had skyrocketed. In Philadelphia the population went from 120,000 in 1850 to 850,000 in 1880. NYC from 700,000 in 1850 to almost 2 million in 1880. With all those people packed into now modern rising cities and dependent on public services to allow people to...

The winter of 1989-1990 in the eastern 2/3rds of the nation had been brutal. November 1989 started mild in the western part of the nation, and a bit cooler in the East it was nothing out of the ordinary. The weather, however changed dramatically in late November. It turned very cold with frequent snowstorms in the central states and the east. In the Midwest temperatures averaged, in some places more than 15 degrees below normal, and it ranked as one of the 5 coldest Decembers on record, and the fierce winter was just getting started. At the end of December, just a day...

Tamarack, California sits up in the high Sierra of that state at an elevation of 6,913 feet. Located just south of Reno and Lake Tahoe it is home to one of the premiere ski venues in the United States and even the world for that matter, and for good reason. Snowfall averages an incredible 443” a year. Because of its location in the High Sierra it is prone to getting hit by one strong pacific storm after another loaded with copious amounts of moisture that sometimes stream all the way from the central pacific. That moisture stream, often known as the Pi...

Dust from the Sahara Desert in Africa is the main source of dust in the atmosphere on a yearly basis across the world. The dust has its origins principally in the remains of centuries old dry lake beds, mainly in the country of Chad. This dust is presentient and often times lifts into the low atmosphere creating a general haze across north central Africa. Because of its presence, storms and seasonal, or trade winds often pick up huge amounts of the dust and dirt and send it thousands of miles away from Africa – sometimes halfway around the world. The presence of...

The Battle of the Monitor and Merrimack occurred on March 9, 1862,. It was the first battle between ironclad warships. The Northern-built Merrimack, a conventional steam frigate, had been salvaged by the Confederates from the Norfolk navy yard. With her upper hull cut away and armored with iron, this 263-foot ship resembled, according to one contemporary source, “a floating barn roof.” The ship had destroyed a fleet of wooden warships off Newport News, Virginia in the days leading up to the battle. The Union ironclad Monitor arrived the night of March 8. This 172-foot “Yankee Cheese Box on a raft,” with its water-le...

Cold air had been holding across the Midwest during the first week of March in 2008. Storms had been frequent in that region during that time, but none of them particularly strong. That changed on March 8, 2008. A major storm moving across the Tennessee Valley brought snow to the Midwest, strong thunderstorms to the Southeast and heavy rain and flooding the Northeast. Columbus, OH set a 24-hour maximum heavy snowfall record of 15.4“. The storm total reached more than 20 “. Memphis, TN received 1.4“ of snow, breaking the daily record. Jackson, TN also had an inch of snow, breaking their daily record. Trenton, NJ had a dail...

The first week of February 2008 was a tough one for the western US as a powerful storm moved onshore. The storm’s height culminated on February 7. There were several areas of very heavy rain with some places having nearly 10“ while winds gusted to more than 100 mph. Loma Prieta, CA had nearly 10“ of rain and Marysville, Ca had just over 9“. Winds gusted to 163 mph near Tahoe City, CA with a 149 mph wind gust at Mammoth Mountain. Snow was also impressive with a whopping 132“ in Kirksville, CA and 62“ in Wolf Creek Pass Colorado. At height of the storm it was estimated that nearly 2 mil...

Tropical systems that reach Hurricane strength in a region near Australia are known as Cyclones. Cyclones that impact the northern and east coast of Australia are fairly common, but the strongest systems usually steer north of the Island Continent. But on March 5, 1899 one of the most powerful Tropical Cyclones ever to strike the region caused unimaginable damage. Cyclone Mahina was the deadliest cyclone in recorded Australian history, and also likely the most intense tropical cyclone ever recorded in the Southern Hemisphere. A pearling fleet, based at Thursday Island, Queensland was anchored in the bay before the storm. Within an...

On March 4 1909, William Howard Taft was to be sworn in as the 27th President of the United States. The night before a fierce storm struck the East Coast and all but shut down travel. With Temperatures well below freezing snow began on the afternoon of March 3 in Washington DC and continued into the after dawn hours of Inauguration Day, which at the time was still held on March 4th. The blizzard left more than 10” of snow. The inauguration ceremony was moved indoors, into the Senate Chamber, limiting the number of persons who could attend. Despite the adverse weather conditions, the ina...
