Brian’s exclusive forecast for Baltimore, Washington DC, and Annapolis:
Tonight: Cloudy with snow developing after midnight. Low around 25.
Thursday: Snow in the morning, then cloudy through noon. Afternoon clearing. High around 32. Total accumulation 2-4″ in Annapolis & Washington D.C.
Thursday Night: Clearing and cold with a low around 15.
Friday: Sunny and cold with a high near 32.
The National Weather Service has posted winter weather advisories and winter storm warnings for central and southern Maryland beginning at 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 4-8″ of snow may fall. Farther to the north, Washington DC, Annapolis, and Easton may see 2-4″ of accumulation, but from Baltimore to the Mason-Dixon line only a coating to an inch is expected. The heaviest snow is expected to fall between 4 a.m. and 8 a.m. Although the center of low pressure will move far to the south of central Maryland, a wide shield of precipitation will spread out to the north during the storm’s trek across eastern North Carolina. 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.
