Flash Flood Threat to Persist Next 24-48 Hours

Lead Forecaster Daniel Crawley

Our region has seen locally heavy rainfall throughout the entire week but here on Saturday night we are experiencing our first widespread rain from this frontal system and quite honestly for the first time this summer.

Thunderstorms began to intensify along the blue ridge around 5 o’clock today, that along with an outflow boundary from South Carolina has collided across the foothills and western piedmont. Most everyone tonight has seen significant rainfall of a half inch or more. Looking at the Doppler estimates below, anyone in the orange shading has seen 1-2 inches. The red shading is over 3 inches and the purple shading are estimates in excess of 4 inches.

The bad news is that we remain in a stagnant pattern with deep tropical moisture in place and a surface boundary serving as the trigger to spark new storms. The expectation is for Sunday and even parts of Monday to feature additional storms.

Training of cells tomorrow afternoon could result in additional and more widespread flooding potential. A short fused Flash Flood Watch could possibly issued by the National Weather Service.

Stay Weather Aware!
