The episode as NWS LWX wrote it up.
A landspout, or dust devil, developed from fair weather clouds around 3:30 PM EDT over the city of Harrisonburg. It only lasted one minute, but it caused about $2000 in damage to a store on High Street. The landspout produced very localized winds strong enough to push an employee of the store back inside. The wind also ripped and buckled the southwest corner of the store's tin roof. Free standing flowers 20 yards away from the structure were left untouched. In addition, the wind loosened shingles on a home nearby.
