Brian’s exclusive forecast for Baltimore, Washington DC, and Annapolis:
Today: Mostly sunny with some afternoon clouds. Milder with a high in the upper 30s to lower 40s.
Tonight: Cloudy with snow developing after midnight. Low around 25.
Thursday: Morning snow showers, then afternoon clearing. Total accumulation of 1 to 2 inches. High near 32.
After another frigid day on Tuesday in which morning lows dropped into the single digits and afternoon highs struggled to reach the mid and upper 20s, today’s weather will feature milder conditions under a mostly sunny sky. A weak cold front will approach Baltimore and Washington today, resulting in a milder flow of air from the south. This will enable afternoon highs to reach the upper 30s to lower 40s. Colder air will overspread the region tonight, which will set the stage for a period of light snow after midnight. The snow will be associated with a “southern slider” storm that will bring a significant accumulation of snow to southeast Virginia where 6 to 12 inches can be expected. A moderate snowfall is anticipated over southern Maryland and the lower Maryland Eastern Shore where 3-6″ of snow may fall. Farther to the north, Washington DC, Annapolis, and Easton may see 1-2″ of accumulation, but from Baltimore to the Mason-Dixon line only a coating to an inch is expected. The combination of accumulating snow and temperatures below freezing has prompted the National Weather Service to issue a Winter Weather Advisory for Baltimore, Washington DC, and Annapolis effective midnight tonight through noon on Thursday. The heaviest snow is expected to fall between 4 a.m. and 8 a.m. Temperatures in the lower to middle 20s will result in snow-covered and icy roads during the morning commute. Once the storm departs the area, a clearing sky is likely during the afternoon hours; however, it will be blustery and cold with a high only around freezing. Lows by Friday morning will fall to near 10 degrees. The upcoming weekend will feature increasing clouds on Saturday with a chance of mixed precipitation by Saturday night.
