A fast moving ripple in the atmosphere produced bands of gusty snow showers early this morning. In some places, the wind-whipped snow fell heavily for a brief time, icing over roads.
Snow totals across the region were generally a dusting to one inch. However, a narrow area of heavier totals of 1-3 inches fell in northern Calvert and Anne Arundel counties.
Some of the worst travel conditions were reported in northern Montgomery and Loudoun counties where the combination of the snow squalls, subfreezing temperatures and gusty winds reduced visibilities and made for very slick roads. Even after the snow bands moved through, Capital Weather Watcher Kenneth James described blowing and drifting snow and even “ground blizzard” conditions in Loudoun.
Officially, Reagan National airport received 0.2 inches, Dulles airport 0.6 inches and BWI airport a trace of snow (through 7 a.m.).
