It would be remembered as Snowmageddon. On February 5 and 6, 2010, the DC beltway area was blanketed with almost 18 inches of the freezing white stuff, the fourth-worst blizzard to strike the area since anyone had been keeping track. At Dulles, it would end up being the snowiest, that airport recording an impressive 32.4 inches. Needless to say, much of the federal government came to a screeching halt.
The government, at least, would quickly recover.
