"Snowmageddon"

On this date three years ago, Washingtonians survived a devastating blizzard that will forever live in the annals of weather history as being one of the most significant winter storms in the Metro Area.  Dubbed "Snowmageddon" and the "Superbowl Storm," this winter storm spanned two days and ended early on Superbowl Sunday.  The storm's first six to eight hours produced wet snow in the suburbs and wet snow and rain in the immediate Metro Area. Colder air was drawn into the storm and the snow became drier and drier but the weight of two feet of relatively dry snow on top of the first six inches of wet snow was too much to bear for many trees and shrubs. Power outages were widespread and the Federal Government even closed for four consecutive days.  It took days for roads to be cleared and power to be restored due the magnitude of the 4th largest snowstorm on record for the Nation's Capital.

The 17.8 inches that fell at National Airport narrowly passed the 17.1" that fell during the January 1996 snowfall and the 16.7" that fell on President's Day 2003.  Having a second Top Ten snowfall in the Nation's Capital during the same winter had not been recorded before the 2009-2010 winter as the December 2009 storm produced 16.4" at National Airport making that the 7th largest snowfall on record until the February blizzard pushed it to eighth place.

The 32.4 inches at Dulles Airport during "Snowmageddon" also set a record for largest two day snow total on record surpassing the 23.2 inches that fell during the two day snowstorm in January 1996.  This storm developed as an area of low pressure along the Gulf Coast intensified rapidly.  It continued to strengthen as it moved up the East Coast of the United States.  This storm was a Mid-Atlantic storm as heavy snow fell in Philadelphia but not New York or Boston where under an inch fell.
