The episode as NWS LWX wrote it up.
An area of showers and thunderstorms moved across Central Maryland between 4:45 and 6:15 PM EDT. The strongest of these storms moved across Prince Georges and Anne Arundel County, producing winds in excess of 55 MPH, small hail, frequent lightning, and very heavy downpours. A government building near Auth Road in Camp Springs had a plate glass window on the northwest side of the structure blown out by high wind. Law enforcement reported several trees and power lines downed, mainly concentrated in the Camp Springs and Forestville area. 35 electrical wires were downed by fallen tree branches in the Baltimore and Annapolis area. 17,500 customers across Central Maryland and Southeast D.C. lost power as a direct result of the storm. Lightning was also a devastating part of the storm. One man standing near a bulldozer on Olney-Laytonsville Road in upper Montgomery County was struck by lightning around 5:00 PM EDT. He survived the strike but was in serious condition from hand and foot injuries. Lightning damaged electrical appliances in a home in the Hillsmere community, just south of Annapolis, around 5:35 PM EDT. Lightning also started a fire at a townhouse in Temple Hills around 5:37 PM EDT. Two brush fires were also ignited by lightning in Anne Arundel County. Heavy downpours from the storms were also a contributing factor in a fatal accident in Glen Burnie. A 21 year old man was killed around 5:30 PM EDT when his car hydroplaned on a curve and hit a tree on Interstate 895 near Ritchie Highway.
