...Summary...
The National Weather Service in Baltimore MD/Washington DC has
confirmed a brief tornado near Broad Run in Fauquier County Virginia on
August 11 2017.

Numerous trees were uprooted and large branches snapped along a
1.2-mile long path that paralleled John Marshall Highway just to
its south. Some trees fell on power lines and homes. The tornado
touched down as the circulation crossed Blantyre Road between
Trapp Branch Road and Georgetown Road, then tracked east and
lifted two minutes later shortly after crossing Beverly's Mill 
Road a quarter mile south of John Marshall Highway.

KLWX Doppler Radar and FAA Terminal Doppler Radars showed a
rotating supercell with a classic hook echo signature crossing
these areas between 608 and 610 PM. Tree damage showed a
convergent signature, implying rotation reached the ground.

Appreciation is extended to Fauquier County and the Virginia
Department of Emergency Management for assistance in conducting
this survey.
