.DISCUSSION...
Widely scattered showers and thunderstorms will develop across 
the lower Mid-Atlantic this afternoon and evening, resulting in
localized rounds of wetting rainfall. Increased clouds will 
maintain slightly higher minimum relative humidity compared to 
the previous couple days, with minimum RH holding at 40 percent 
or above areawide. Surface winds will gust in the 10 to 15 mph 
range this afternoon from the west. 

A potential remains for heavy rain and localized flash flooding 
to occur across the Piedmont on Friday, more so east of a line 
extending from Yadkinville, NC to the City of Lynchburg. 
Scattered rounds of wetting rainfall will continue on Saturday 
before drier air returns on Sunday.
