A line of heavy thunderstorms has developed ahead of a cold front moving across the Appalachian Mountains. With a very hot and humid air mass in place across our area, these storms will likely remain intact and approach the metro Washington area around 8 pm. Some of these storms could be severe and will be capable of producing very heavy rain, high winds, hail and very strong wind gusts. The activity should be mostly east of the Chesapeake Bay by midnight.

The front will stretch out between the Eastern Shore and Southeast Virginia tomorrow and may become stationary. This will keep conditions very warm and humid tomorrow with more showers and thunderstorms possible. While some improvement in temperatures and humidity levels is expected on Thursday, isolated thunderstorms will still be possible...especially south and east of Washington.
