NWS Warns Of Severe Storms Tonight And Thursday

The National Weather Service has issued a Hazardous Weather Outlook for Wednesday and Thursday because of showers and thunderstorms that could produce high winds, flash flooding and other severe effects.

Some are sounding the derecho alarm to describe what’s possible for this batch of storms, though many forecasters say the risk of that is low in the D.C. area. What could strengthen the storm system is a cold front rare for mid-June.
