PM Update: Unseasonably cold with rain/snow mix late Wednesday

Today’s high temperatures only managed to reach the mid-to-upper 40s across the region. At Reagan National, the high of 48 was the coldest Presidential Election Day on record (since the late 1800s). With cold air in place and a Nor’easter developing Wednesday, a wintry mix of precipitation is possible during the second half of the day.

Through Tonight: Skies are mostly cloudy and it’s cold. Lows range from 29-35 (suburbs-city). Winds are from the north at 5-10 mph.

Wednesday: Rain or rain mixed with snow develops from east to west, mainly in the afternoon. By late afternoon, precipitation may transition more to snow where precipitation falls steadily, most likely northeast of town. Mixed precipitation is expected late into Wednesday night, especially east of I-95. Little or no snow accumulation is likely except towards Baltimore where a coating to one inch is possible. Wednesday’s highs are almost 20 degrees below normal, just 36-41. Chance of precipitation is about 60 percent inside the beltway, decreasing to the west and southwest, and increasing to the east and northeast.
