Broad Area of Light Snow Moving into Southern VA

At 11:30 PM Monday, Doppler Max 6 indicated a broad area of light snow moving north-northeast through southern Virginia. Much of this precipitation was evaporating before reaching the ground, but portions of southwest Sussex county, Greensville county, Brunswick county, and Mecklenburg county are likely beginning to see the snow reach the ground. The winter weather advisory and winter storm warning remain as they were earlier in the evening, with the greatest snowfall expected across southeast Virginia. The Richmond metro area should see at dusting to 1" of total snowfall, with greater amounts south and east. Meteorologist Carrie Rose will be in the CBS 6 Storm Center early tomorrow with the very latest.

Winter Storm to Affect Parts of the Area Tuesday

A winter weather advisory has been issued for much of southern and a small part of central Virginia, and a winter storm warning has been issued for a small part of southern and all of southeast Virginia.

A broad upper trough will continue to dig southward across the Southeast U.S., driving another surge of cold air into Mid-Atlantic overnight tonight. At the same time, a surface low will develop in North Carolina and track across the eastern part of the state and just off the Virginia coast. Areas along and just north of the track of the low will see the greatest snowfall amounts, with 4-6 inches possible in north-central and northeast North Carolina. Southern and southeastern Virginia will see snowfall totals in the 2-4” range, with isolated amounts in southeast Virginia exceeding 4”. I expect Richmond to see periods of light snow, with total accumulations of less than 1”. The track of the surface low is critical as to where the heaviest snow will fall, and slight adjustments to the track could easily occur. I’ll have another update later tonight when new data is available regarding the exact track and intensity of the storm.

Monday Noon Update

Periods of light snow and flurries are expected Monday afternoon in Central Virginia. New light precipitation is forming in western Virginia at Noon, and is moving east toward I-95. Temperatures are above freezing in Central Virginia, so any snow that does fall is not expected to stick on the ground for long before melting. Northwest and far North-Central Virginia may see snow accumulations this afternoon and evening, along and north of Charlottesville and Fredericksburg. There is a Winter Weather Advisory in effect for this part of the state into D.C. and Maryland, where a couple of inches of snow may accumulate, and roads may become slick and hazardous.

Visibilities are much-improved at Noon, as compared to this morning when clouds were as low as 100 feet above the ground, with fog and mist. Not much precipitation actually made it to the ground through the morning hours, though.

Snow shower chances continue into Tuesday for much of the state, but southern and southeastern Virginia have a chance for snowfall accumulation up to 4" in spots. In the Richmond metro area, once again only light snow is expected to fall, with about an inch of snow accumulation possible Tuesday. From South Hill to Williamsburg and points south, 2" to 4" of snow accumulation is possible by the end of Tuesday. A Winter Storm Watch is in effect for far southeast Virginia, from east of Franklin to Suffolk, Norfolk, and Virginia Beach from late Monday night through Tuesday. Up to 5" of snow accumulation is possible in the Watch area.

Wintry Mix To The Southwest

A wintry mix continues to fall in the southwest corner of the state. It is breaking apart as it enters central VA, but we could see a stray snowflake or two overnight tonight. A better chance for flakes will arrive tomorrow afternoon as a fast moving storm passes the area.
