Tuesday into Wednesday will likely hold the first big storm of the winter.
Scenario: The arctic front will stay south far enough to allow warm moist air to override the colder air and cause snow to break out Tuesday. The moist air will be pumped north by a system that will be pushing the precipitation into the area. The southerly winds will slowly warm the atmosphere and a gradual changeover to ice and rain in the southern region.
As of now:
Maryland and Northern Virginia (North of Lexington to Charlottesville to Fredericksburg to Dover Deleware could see 4 to 8 inches of snow. Closer to Pennsylvania may see as much as 12 inches. The differences in precipitation will be areas that mix with sleet and freezing rain. The further south you get the more likely a mix even to rain will occur.
Central Virginia will have a good amount of snow (2 to 4 Inches) before mix and changeover to rain.
Southern Virginia - South of a Roanoke to Farmville to Richmond to Chincateugue line, will see 1 to 3 inches possible, but a mixing with rain and ice and then rain will stop the accumulations and quickly be washed away.
This is based on the latest guidance and it will likely adjust over time as we get closer to the event.
More to come!
