A large upper level low pressure system passed east across the northern Great Plains, drawing deep moisture along the Appalachian Chain from the Gulf of Mexico. An upper level disturbance moved across the central Appalachians early in the day, pushing a line of showers with heavy rain across the forecast region. While a break in rainfall developed across the mountains and foothills behind the line of convection, the line stalled east of Danville and Lynchburg, where prolonged periods of heavy rain fell throughout the afternoon. A cold front entered the Mountain Empire and southeast West Virginia during mid-afternoon, triggering another round of heavy showers and isolated thunderstorms that quickly filled in ahead of the boundary. For the entire event, one to three inch rainfall amounts were common across the entire forecast region.
In addition to some reports of flash flooding, river flooding was also observed from Halifax through Buckingham Counties. The Roanoke River at Randolph was among those most affected, with the river rising to the moderate flood stage of 24.9 feet.
