Details from NWS storm survey: A small tornado touched down at the entrance to the Jefferson Crossing Shopping Center on Flowing Springs Road just north of U.S. 340. The tornado damaged the sign at the entrance. The tornado crossed Flowing Springs Road and damaged the roofing of three barns and the door to a fourth barn located at Hollywood Casino at Charles Town Races. One barn lost a section of roof completely, leaving seven stalls exposed. Debris from the roof of one barn was thrown into power lines, snapping a telephone pole. Fencing was also damaged by debris from the roof. Projectile impacts were also noted in nearby barn roofs from two- by-four pieces of wood that were lofted by the tornado. The tornado lifted as it crossed East Fifth Avenue near the vehicle entrance to the barn area. The tornado was captured on security camera footage at the Hollywood Casino at Charles Town Races. The footage showed sections of barn roof being lifted and spun into the air. Velocity data from the FAA Terminal Doppler Radar located near Leesburg VA that serves Washington Dulles International Airport corroborated these impacts with a brief, weak shear signature from 0014 to 0015 UTC.
