UPDATE 4:20 PM: Counties that were previously under a winter storm watch south of Roanoke are now under a winter storm warning. Counties that were not under a winter storm watch, including Roanoke, have now been placed under one. Widespread 6-10 inches is forecast by the weather service (does that sound familiar?) Click here for latest from the National Weather Service. END UPDATE
I will have more later, but for now: Forecast models have come consistently northward with heavy moisture and it now appears that much of the southern half of Virginia will experience a significant (4-plus inches) to major snowstorm (10-plus inches) Friday night into Saturday. The Hydrometerological Prediction Center is still in the process of updating its snowfall risk maps, but our region is now squarely within the high risk of 4-plus inches. Also, moderate risk of 8-plus, slight risk of 12-plus. More to come. Stay tuned.
