Five years ago, the D.C. area was being pummeled by a series of storms which dropped record snow over a 9-day period. The first of the storms happened on the 2nd and 3rd of the month, dropping a measly 3.3 inches of snow at Reagan National. The second storm which occurred on the 5th and 6th, ended up becoming a record blizzard and earned itself the name "snowmageddon."
February 5-6, 2010 Storm Snowfall Amount Dulles International: 32.4 inches; two-day snowfall record BWI Thurgood Marshall: 25.0 inches; two-day snowfall record Reagan National Airport: 17.8 inches; second highest two-day snowfall record
The Feb. 5-6 blizzard dropped incredible amounts of snow in the area. From the National Weather Service Sterling, VA office,
"This was the first time (since snowfall records were kept in 1884) that Washington DC recorded two separate double digit snowfalls in the same month. The one week snowfall record for Washington DC was also bested with a total of 28.6”. The previous record was 28.0”, set in 1922 during the famed Knickerbocker Storm."
The two-day total of 17.8 inches at Reagan National Airport was less than one inch away from the 18.7 inches from the February 18-19, 1979 storm and not far behind the infamous “Knickerbocker” storm that dropped 26 inches in two days from February 12-13, 1899. At Dulles International, 32.4 inches wiped out the previous two-day storm record of 23.2 inches on January 7-8, 1996 while 25 inches at BWI Marshall barely beat out the two-day storm record of 24.4 inches.
Another blizzard on the 9th and 10th of the month dropped an additional foot to two feet of snow. The total for the month of February 2010 at Reagan National was 32.1 inches. Dulles International had a whopping 46.1 inches for the month while BWI Marshall recorded an incredible 50 inches with a snow depth of 34 inches right after the storm on the 11th.
