1 to 2 inches possible Tuesday night
Just to keep us in the mood, the winter of 2009-10 is preparing to dish up another taste of the season tonight as two low-pressure systems converge on the mid-Atlantic. One is approaching from northern Illinois, while the second moves up from the south to become the latest coastal system to affect the region.
The NWS at Sterling has issued a Winter Weather Advisory for all Maryland west of the bay except Calvert and St. Mary's counties, where the precipitation could be rain depending on where the rain/snow line settles. The advisory calls for 1 to 3 inches of snow elsewhere across the region by daybreak Wednesday.
The snow would begin in the southwestern portions of the forecast area, down in Virginia, with 1 to 2 inches by early afternoon if the forecast holds up. The precipitation, starting as rain south and east of the I-95 corridor, would then and move north and east, reaching the Baltimore area in the late afternoon, between 5 and 7 p.m., forecasters said.
Snow accumulations would begin sometime after sunset Tuesday, with 1 to 2 inches in the DC area.

Meanwhile, forecasters are continuing to watch the weekend weather. An offshore track would ensure we get mainly snow here, but limit the amount of moisture available, they said. A more northerly track would bring more moisture, but slide the rain/snow line closer to the metro areas.
