The current image above shows the Risk for Severe Thunderstorms on Wednesday afternoon and evening (courtesy Storm Prediction Center). The best chance of severe thunderstorms will be across southern Maryland, Fredericksburg and the northern Neck of Virginia.
The following images are from the High Resolution NAM (North American Model) timing the potential line (lines) of strong thunderstorms (images courtesy tropical tidbits):
1 pm Wednesday: Scattered showers
4 pm Wednesday: Scattered showers and Thunderstorms
7 pm Wednesday: Nasty line of storms may be approaching the Metro Area from the Blue Ridge mountains.
10 pm Wednesday: Line of strong to severe thunderstorms moving across the 95 corridor between Baltimore, Washington and Fredericksburg.
1 am Thursday: Storms moving across the Chesapeake Bay
Bottom Line:
- Rainfall totals of around one inch are likely with some locations receiving thunderstorms possibly picking upwards of 2 to 3 inches.
- Strong thunderstorms have the potential to reach severe limits Wednesday afternoon with damaging wind gusts (above 58 mph), cloud to ground lightning, torrential rain and isolated tornadoes.

It didn’t take long for our interest to change from snowstorms to severe weather, but I guess beggars should not be choosy.
We just got one of the great snowstorms in history and I am already complaining a month later.
