A stalled frontal boundary acted as the triggering point for an initial line of showers and thunderstorms, with many of the storms becoming severe with strong moisture advection combining with diurnal heating and leading to an unstable air mass. The remnants of Tropical System Bill moved through the Mid-Atlantic overnight, continuing the severe threat late into the early part of the overnight hours. As winds backed with the tropical system, increasing directional and magnitude shear led to the development of tornadoes.

Location: BRISTOW
Tornado F-scale: EF0

Reported by: NWS Storm Survey

National Weather Service personnel completed a ground survey along with radar analysis and concluded a small tornado produced damage along a 2.1 mile path beginning near the intersection of Virginia State Route 28/Nokesville road/ and Linton Hall Road. The tornado then moved northeast along Route 28, ending it���s damage path at the baseball fields at the intersection of Godwin road and Route 28.
The tornado���s path width was approximately 100 yards. The bulk of the damage occurred at the Broad Run golf training center where about a half-dozen softwood trees between 12 and 18 inches in diameter were snapped approximately 4 feet above the ground.  The damage at the baseball fields at the intersection of Route 28 and Godwin Road included a scoreboard secured by 4x4s being snapped, along with
baseball dugout roofs lifted and blown away. The damage was sporadic along the 2.1 mile path, but coincided with the tornadic signature as depicted on WSR-88D and FAA Terminal Doppler weather radar. No additional damage was noted northeast of Godwin road.
