Wider weather episode

A warm front was situated across central Virginia and North Carolina, while a stationary front was positioned across Kentucky and West Virginia, which kept a highly moist airmass over the region. Lift across the warm front and increasing instability via diurnal heating through the day resulted in an increase in coverage and intensity of storms. Some of the storms were severe producing damaging winds and large hail. One intense thunderstorm passed across the City of Martinsville, VA, with the heaviest rain falling between 5 pm and 6 pm EDT, occurring at rates of 4 to locally as high as 6 inches per hour. Two to 2 and a half inches of rain fell across the city, with one local weather station observed a total of 2.25 inches occurring during a 45-minute period. MRMS Crest Unit Stream flow in the City of Martinsville was observed to be 1,540 cfs/mi^2 at 6 pm EDT, with any values above 1,000 cfs/mi^2 being very strong indicators for the potential of flash flooding.
