Winter Weather in Eastern Loudoun, Virginia

Low pressure in the southern stream of the jet passed by just to the south on the morning of the 7th. However, temperatures were marginal due to the lack of cold high pressure to the north. Therefore, precipitation began as rain east of the Blue Ridge Mountains where low-level warm air held on. However, colder air did eventually work its way in causing precipitation to change to snow. Farther west for locations near the Blue Ridge Mountains and westward, precipitation fell mainly in the form of snow.

Snowfall accumulations ranged from around 1 to 2 inches near Interstate 95, with 3 to 6 inches near the Blue Ridge Mountains into the Shenandoah Valley. Snowfall accumulations were around 1 to 3 inches farther west toward the Potomac Highlands due to less precipitation.
