DISCUSSION: Areas from northeastern Virginia through southwestern Connecticut are under a slight risk to see severe weather today, according to the NWS Storm Prediction Center. A cold front moving through Pennsylvania this afternoon will be the trigger to initiate the thunderstorms. Ahead of the cold front, dew points are abnormally high, with widespread mid-to-upper 70s and even a dew point of 80 at Reagan International Airport in Washington, DC. These sultry dew points increase the chance for intense downpours within thunderstorms, so a Flash Flood Watch has been issued for many of the same areas that have a slight risk of severe weather. After a few morning showers, skies have cleared across eastern portions of Pennsylvania, Maryland, Virginia, southern New Jersey and Delaware. As a result, the lower atmosphere has become more unstable in these areas, allowing for more favorable conditions for thunderstorms to grow. In terms of severe conditions, damaging winds will be the primary threat today, although isolated hail or a tornado can't be ruled out.
Anytime severe weather threatens your area, be sure to prepare for extreme conditions. Listen to local news or radio programs to stay ahead of the storm, and have a generator ready in case the power goes out for extended periods of time.
