Brian's exclusive forecast for Washington DC:
Today: Sunshine with occasional cloudiness. Mild with a high from 65 to 70.
Tonight: Variable cloudiness. Turning colder with a low in the upper 30s.
Sunday: Clouds and sun early, the more sun later in the day. Cooler with a high in the mid to upper 40s.
Sunday Night: Mostly clear with a low around 30.
Monday: Mostly sunny and chilly with a high near 40.
The extended forecast calls for a chance of snow on Tuesday with a low around 30 and a high near 35. Windy with sunshine on Wednesday. The low will be around 30 and the high will be near 40. Mostly sunny on Thursday with a low around 30 and a high near 50. Clouds and sun on Friday with a low around 35 and a high near 55.
Temperatures this afternoon are in the mid 60s to near 70 under a mostly cloudy sky. Veiled sunshine can be expected through the rest of the day along with gusty winds as a cold front moves from west to east across the region. Colder and drier air will overspread the area later tonight with temperatures dropping into the upper 30s by Sunday morning, more than 30 degrees colder than today's highs. High pressure will briefly build over the Mid-Atlantic states resulting in plenty of sunshine on Sunday and Monday but also producing cold temperatures. Highs on Monday will struggle to reach 40 (average highs for this time of year are in the upper 50s). Our attention will then be focused on the south where computer models are indicating the potential for a spring snowstorm from Delmarva to New England. The trend of the computer models over the past two days is to keep this storm far enough off the eastern seaboard to keep the heaviest precipitation away from Baltimore and Washington, but impacting eastern Delmarva with the potential for moderate snow, strong winds, and coastal flooding. In this scenario, light snow may fall west of Chesapeake Bay from Tuesday afternoon into Tuesday evening with perhaps an inch or two accumulating by late Tuesday night. Should this storm move 50 to 100 miles west of its current forecast track, the heavier snow would overspread central Maryland. As the center of low pressure moves to the northeast, its center will deepen rapidly and become a powerful nor'easter in southern New England where heavy snow can be expected from Connecticut through Maine.
