The episode as NWS PBZ wrote it up.
An unstable environment, plus residual outflow boundaries from previous convection, helped to expand thunderstorm coverage during the evening of the 29th and into the early morning hours of the 30th ahead of a sagging cold front. Storms pushed across Preston and Tucker Counties starting after 10 PM on the 29th. Periods of moderate to heavy rain occurred until around 5 AM the following morning as backbuilding storms continued through the night. Rainfall totals of 2 to 4 inches were observed over southern portions of Preston County and over much of Tucker County, resulting in some reports of flash flooding. A few water rescues were necessary at Arnold Park Campground, as well as in Jenningston.
