The National Weather Service has issued a Winter Weather Advisory for Baltimore, Washington DC, Annapolis, and the western shore of southern Maryland effective 1 a.m. Wednesday through noon Wednesday. A upper-level trough will develop and push through the area early Wednesday, producing a period of light to moderate snow. Unlike this morning's snowfall, which produced 1 to 3 inches (the heaviest south of DC and Annapolis), tomorrow's snow will fall before sunrise and with temperatures below freezing. This will result in slick conditions developing on roadways. Main thoroughfares should remain wet throughout the event, but secondary roads could become snow-covered and icy for a time. The snow should end by mid or late morning, with sunshine and above-freezing temperatures expected later in the day.
