A storm system brought rain and snow to the Middle Atlantic and New England states yesterday and overnight. The rain snow line rain through Washington, Baltimore, and Philadelphia with rain to the south and a burst of snow to the north. Eventually the rain/snow line moved north through Philadelphia and over New York City and coastal New England. Even eastern Massachusetts saw snow turn to a cold rain. At 7 a.m. this morning, the low is moving quickly out of New England where a wide range of snow totals has been recorded (although a bit less than was expected in some areas.) Accumulations were generally 2 to 4 inches along the coast and 4 to 8 inches inland. Today's weather will feature abundant sunshine in the Chesapeake area, although it will be chilly with a wind from the west that will occasionally gust over 25 miles per hour. High pressure will build over the region through Monday with lows tonight dipping into the 20s and highs on Monday only near the freezing point. On Tuesday, a cold front will sweep through the area with some clouds and perhaps a few snow flurries. This will be followed by a brief cold snap on Wednesday with highs only in the 30s. Later in the week, temperatures will moderate considerably: 40s on Thursday, 50s on Friday, and 60s on Saturday. As we move into next weekend, another cold front will approach the region along with the potential for storminess.
