Winter Storm Watch higher elevations North and West of D.C.
Winter Weather Advisory Northern and Western suburbs of D.C.

A low pressure system will develop tonight off the coast of SC and steadily move north/northeastward through the day tomorrow. Given today’s warm temperatures and a lack of an arctic air mass, this system will bring mostly, if not all, rain to areas along and east of I-95. Because this storm will have to generate its own cold air…areas of measureable snow will likely be at higher elevations north and west of D.C. And the higher the elevation, the better chances there will be of more measurable and impactful snow. Rain will overspread the metro area during the overnight hours. And a change to snow will occur shortly thereafter at higher elevations. The metro area might see the rain end as snow later tomorrow afternoon or early evening. An upper level system may bring periods of rain and/or snow to parts of the area Thanksgiving Day.

Predicted Snowfall Wednesday
