A powerful winter storm is pounding the south and will work it's way to the Mid-Atlantic and then the Northeast. A winter storm warning is in effect for the entire D.C. area, with the exception of St. Marys and Calvert counties in Maryland, as sleet and rain will mix in to keep the totals lower. I expect the clouds to increase through the day. Snow starts after the evening commute. Here's a timeline to get you through tonight/early Thursday.
Snow will mix with sleet at times along and east of I-95 starting Thursday perhaps as early as sun up. What time and how far west that mix line goes will determine snowfall totals. If it stays east of I-95 and D.C. stays snow, our numbers will be in the high end of the 4-8" range with a few spotsllikely getting more. If the sleet and rain mixes early and stays put, we will see more like 4 or 5" in the city. Here's our best estimate on totals on the ground.
- Forecast Snow Totals through Thursday
Moisture starts cutting off in the afternoon on Thursday and will be gone altogether Thursday night. Friday will be quiet during the day, but a weak clipper could bring some flurries or light snow overnight on Friday into Saturday. Otherwise quiet this weekend and staying cold.
