SPC Convective Outlook for Thursday
Flash Flooding Possible for Portions of the Mid Atlantic and North Carolina Thursday
Rain and thunderstorms are expected to develop behind a stationary front off the East Coast. Given the rich moisture in place, slow moving showers and thunderstorms, and recent heavy rains, excessive rainfall will be possible. Widespread rainfall accumulations of 1-3 inches with locally higher amounts in excess of 4 inches will be possible. These heavy rains may lead to flash flooding in flood prone areas.
Accumulated rainfall through 2am EDT Friday
