1983
A huge snowstorm known as the "Megalopolitan blockbuster snowstorm" swept up the eastern seaboard, burying the Mid-Atlantic area from northeastern Georgia to eastern Maine with very heavy snow. During the late evening, low pressure over Georgia started giving a light snow to the Baltimore-Washington, D.C. area. The snow slowly picked up in intensity during the overnight hours and by morning the surface low was positioned just east of Wilmington, NC. A tight pressure gradient between the storm and high-pressure to the north caused winds to increase, gust over 40 mph and snowfall rates of 3 inches per hour were common. Many observers particularly in the Maryland suburbs reported several episodes of lightning and thunder. Most of the southern and eastern suburbs recorded 15 to 20 inches of snow while 20 to 30 inches of snow fell in the northern and western suburbs. National Airport received 16.6 inches while 22.8 inches fell at both BWI and Dulles Airport. In Northwest Montgomery and Frederick Counties in Maryland, the storm was the greatest ever recorded easily exceeding the totals received during the famous “Knickerbocker” storm of January 1922. Germantown and Frederick, MD both received 30 inches of snow and western Loudoun County, Virginia, up to 38 inches. Braddock Heights, just west of Frederick, MD, received 34.9 inches. Areas to the east and a little south of Washington received snow pellets mixed with snow thus reducing their accumulations. In Pennsylvania, the storm produced 21 inches at Philadelphia, 24 inches at Harrisburg, and 25 inches at Allentown. New York City received 22 inches of snow and 35 inches were reported at Glen Gary, located in the Blue Ridge Mountains of West Virginia. Windsor Locks, CT received a record 19 inches of snow in 12 hours. 5 inches of snow in one hour was recorded at Allentown, PA and Hartford, CT. Winds gusted to 72 mph at Chatham, MA.
