March is known to feature some crazy and surprising weather and the 1958 blizzard that occurred in the Mid-Atlantic region between March 18th and 23rd was indeed rather unexpected. In general, forecasts on the morning of March 18th had no mention of snow. This was in an era when computer forecast models were just in their infancy and it was even before satellite imagery existed which could aid in the forecast. By afternoon on that particular day, the light rain had changed into huge, wet snowflakes and - for the next few days - history was being made.

The winter of 1992-1993 was not bad at all in the Mid-Atlantic region in terms of cold and snow, but one storm at the end of the season will put that particular winter in the history books forever. One of the most intense storms ever observed in the eastern US took place from March 12-14, 1993 and it will be forever known as the “Storm of the Century”. This intense storm generated tremendous snowfall totals from Alabama through Maine, high winds all along the east coast, extreme coastal flooding along the Florida west coast and incredibly low barometric pressures across the Southeast and Mid-Atlantic regions. The aftermath of the “Storm of the Century” was unseasonably cold and broke records in many spots for the middle of March. To this day, the storm also known as the “Superstorm of 1993” ranks among the deadliest and most costly weather events in US history.

This Sunday marks the 32nd anniversary of the Space Shuttle Challenger disaster which occurred on January 28, 1986, when the NASA Space Shuttle orbiter Challenger (mission STS-51-L) broke apart 73 seconds into its flight leading to the deaths of its seven crew members. STS-51-L was the 25th American Space Shuttle Program flight since the program began in 1981. It was also the first mission to have a civilian on board, American teacher Christa McAuliffe. The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida at 11:39 EST (16:39 UTC). According to the Report of the Presidential Commission on the Space Shuttle Challenger Accident, weather conditions were likely one of the factors that contributed to the incident. Tests conducted during the subsequent investigation showed that O-rings were much less resilient at lower temperatures, but the extreme cold at the Kennedy Space Center was not the only weather factor involved with this tragedy.

December 1776 was a desperate time for George Washington and the American Revolution. Morale was low, hope for winning the war was diminishing, and the Continental Army led by George Washington was thinning in numbers after many battles lost to the British. December began with lots of rain and muddy travel conditions for the men which did not help with their spirits. After retreating through New Jersey, they set up camp in Valley Forge, Pennsylvania where the army was met with very cold weather that led to plenty of ice on the Delaware River. All in all, things were not looking good for Washington's army.

Forty two years ago on November 10th, 1975, a major storm over the Great Lakes helped to sink the SS Edmund Fitzgerald in Lake Superior and all of its 29 crew members died. When launched on June 7, 1958, it was the largest ship on North America's Great Lakes, and she remains the largest to have sunk there. The Edmund Fitzgerald was in the worst possible location during the worst weather of the ferocious storm. The wind and waves from the west hit the freighter broadside as it tried to flee south to safety in Whitefish Bay. The Edmund Fitzgerald was loaded with about 26,000 tons of taconite pellets on Nov. 9, 1975, at Superior, Wisconsin and was bound for Detroit, Michigan.

On September 21, 1938, one of the most destructive and powerful hurricanes in recorded history struck Long Island and Southern New England. It was the first major hurricane to strike New England since the year 1869. The storm developed near the Cape Verde Islands on September 9, tracking across the Atlantic and up the Eastern Seaboard. The storm hit Long Island and Southern Connecticut on September 21, moving at a forward speed of 47 mph! Today marks the 79th anniversary of storm known as "The Great New England Hurricane of 1938" as well as "The Long Island Express" and the "Yankee Clipper". With no warning, the powerful category 3 hurricane (previously a category 5) slammed into Long Island and southern New England causing approximately 682 deaths and massive devastation to coastal cities and became the most destructive storm to strike the region in the 20th century. Little media attention was given to the powerful hurricane while it was out at sea as Europe was on the brink of war and the overriding story of the time. There was no advanced meteorological technology such as radar or satellite imagery to warn of the storm’s approach.

The sun has been relatively quiet in recent years and the current solar cycle (#24) is actually on pace to be the weakest in over one hundred years. Even weak solar cycles, however, can produce significant solar storms. In fact, it was this time of year back in 1859 when a super solar storm - now known as the Carrington Event - took place during another weak solar cycle (#10). The event has been named for the British astronomer, Richard Carrington, as he observed from his own private observatory the largest solar flare during this event which caused a major coronal mass ejection (CME) to travel directly toward Earth. Fortunately, solar storms of this magnitude are quite rare as it would very likely have a much more damaging impact on today’s world than it did in the 19th century.

On August 21st, the US will experience its first “coast-to-coast” total solar eclipse since 1918. On that day, the moon will pass between the sun and Earth and the result will be a 67-mile wide shadow that will cross the country from Oregon to South Carolina. In the DC, Philly and New York City metro regions, this eclipse will be partial with anywhere from about 81% of the sun being covered by the moon in DC to about 72% in New York City. In the "totality zone" where the sun will become covered in its entirety(and of course depending on the local cloud conditions), the sky gets deep twilight blue, temperatures drop noticeably, the winds should die down, bright stars and planets come out, animals and birds may behave strangely like it’s the end of the day, and it can become strangely silent. A total solar eclipse provides a great opportunity for scientists to learn more about the sun's atmosphere as well as our own.

The high temperature forecast in Death Valley, California for the next couple of days is an impressive 120°F or so, but this is rather pedestrian compared to the all-time record high that occurred on this date one hundred and four years ago. On July 10th, 1913, the weather observer at Greenland Ranch in Death Valley recorded a high temperature of 134°F. One hundred and four years later, this is still the highest air temperature ever reliably recorded on Earth. In addition to this all-time and worldwide high temperature record, the year of 1913 produced numerous other extreme weather events.

Nowadays, when the people of New Orleans think of devastating hurricanes they think of Katrina, but before 2005, the most notorious storm name in Louisiana was Audrey. Sixty years ago today, Hurricane Audrey slammed into the southwest coast of Louisiana and became the earliest major hurricane (category 3) to make landfall in the US. Hurricane Audrey killed hundreds of people – estimated to be somewhere between 400 and 500 - including many of whom to this day remain unidentified and tragically, about one-third of those were children. The high number of deaths - in an era without satellite imagery - were attributed to the storm moving ashore earlier and stronger than predicted while most people were sleeping.
