A portion of the I-95 corridor will continue to receive drenching downpours, thunderstorms and the potential for flash flooding into early Friday morning.

A nearly stalled front stretching from the mid-Atlantic through the Tennessee Valley will focus the activity in a swath from Virginia to North Carolina, South Carolina and Georgia overnight.

Reports From Wednesday's Storms

Slow-moving thunderstorms are responsible for dropping 2 to 4 inches of rain in some western suburbs of Washington, D.C. late Thursday evening. Dulles International Airport recorded nearly 4 inches of rain in the span of just a few hours Thursday night. The heavy rain has led to several reports of street flooding and even reports of water rescues north and west of Washington.

Earlier Thursday evening, 2 to 3 inches of rain fell in the span of just a couple of hours around Lynchburg, Va.

Farther south, Doppler radar estimated that 8.5 inches had fallen Thursday across northern Allendale County, S.C., causing widespread flash flooding.

Moisture coming up from the Gulf of Mexico this July has already brought an excess of rain to much of the mid-Atlantic. The heavy storms Thursday night will continue to re-aggravate the flooding problems from earlier in the month.

Since the front focusing the rainfall Thursday and Thursday night will stall and reverse its motion from earlier in the week, look for showers, thunderstorms and the risk of flooding to expand westward once again to the central and southern Appalachians into the weekend.
