Winter Weather Update: Monday 6:40 AM

A Winter Weather Advisory will be in effect for much of Central Virginia from 4 a.m. Tuesday through Midnight as a snow and sleet mix of precipitation moves in from the south late Monday night. You can see the counties included in purple here:

Those counties shaded in blue in the Northern Neck are under a Winter Storm Watch, where higher snowfall accumulations are possible than for the rest of us. Here's the latest forecast snow map from late Monday through pre-dawn Wednesday:

A winter storm continues to track through the Southeast U.S. early this Monday morning, with cloud-cover ahead of the storm already overspreading Virginia. We will remain cloudy the rest of today and cold with highs about ten degrees below normal in the mid 30's. A wintry mix of sleet and snow will move into southern Virginia this evening and then overspread the entire area from south to north during Tuesday morning. Periods of sleet and snow will persist in Richmond through Tuesday evening (1 to 3" accumulation). There will be more mixing in south central and southeastern Virginia on Tuesday, resulting in lower overall winter precipitation accumulations in that part of the state. Rain, freezing rain and sleet will be possible in these areas (up to a tenth of an inch of ice accumulation). Precipitation form should be mostly snow for areas to the west and north, where accumulations look to be the highest (2 to 3"). The Northern Neck could receive higher totals closer to 5" of snow before sunrise Wednesday as a result of the low pressure system offshore beginning to intensify as it transforms into a nor'easter headed for New England Wednesday.
