Severe Weather- Leesburg, VA

While it may seem strange that severe weather could be possible on a cloudy day with temperatures in the upper 50s, it is happening.  This is the current radar image for areas in and around Leesburg.  The large red box indicates a tornado watch which is in effect until 9 PM tonight.  There is a severe thunderstorm warning (yellow box) on the storm in Shenandoah and Frederick county, which is moving to the east-northeast.  This storm is capable of producing winds up to 60 MPH and heavy rain.  Expect this storm within the next 1 to 2 hours.  I do not expect very many tornadoes to develop today around Leesburg given the lower temperatures and available moisture.  However, that does not completely eliminate the risk.  Winds from the southeast at the surface coupled with winds from the southwest just 10,000 feet from the ground will help thunderstorms to rotate.  I will do my best to keep this updated as severe weather develops.
