The models have come to fairly good agreement that most of the moisture will be out of the area before temperatures fall below freezing across most areas, with the only exception being areas along the Mason-Dixon line. There is still a threat for some minor ice accumulation in there, and as a result, the National Weather Service has issued a Winter Weather Advisory for: Allegany, N. Baltimore, Carroll, Frederick, N. Harford, Garrett, and Washington counties.
Here is the current ice accumulation forecast from the NWS:
Temperatures are still expected to fall throughout the day tomorrow as much colder air flows in behind the front. Saturday and Sunday will be cold, but temperatures should start to climb back to near normal as we head into next week.
