Case Description

Reason for interest: Snowstorm over Mid-Atlantic

This was a classic set-up for a major winter storm which impacted the mid-Atlantic region and was, in general, well forecast several days in advance by large scale prediction models. The system developed near the Gulf Coast, with Canadian air already present over the mid-Atlantic and Appalachian region. This system strengthened rapidly as it moved slowly up the coast producing significant amounts of snow, sleet and freezing rain. Maximum amounts of 30-42 inches of snowfall occurred near the border of VA/WV/MD.
