What the reports say
Written by National Weather Service staff at the time of the event · public domain
A complex low pressure system pushed a warm front through the Mid Atlantic region followed by a cold front. This lead to widespread thunderstorms that produced severe weather. In Maryland, the severe weather reported was large hail and some flash flooding. In Caroline County near Denton, golfball-size hail fell for nearly 10 minutes and covered the ground. In Talbot County near Royal Oak and Newcomb, golfball-size hail piled up to a depth of 4 to 5 inches deep. In Frederick County, flash floods washed out roads between Brunswick and Jefferson. Lightning struck a business in Edgewater of Anne Arundel County, causing $100,000 damage.
An off-duty NWS Employee reported penny size hail north of Glenmont. Trained Spotter and Amateur Radio operators reported penny size hail from 5 miles northwest of Beltsville to Colesville to 3 miles west of Burtonsville.
