The tornado then strengthened to EF2 status along a 2 mile continuous path, from Watts Trail through North Fork Church Road to Lowery road. In this path approximately 15 telephone poles were snapped off, thousands of trees were downed, and 3 homes had windows blown out, roofs damaged, or trees falling on them. Numerous barns and outbuildings were also destroyed. the tornado then weakened as it approached Lowery Road before lifting. Near Lowery Road one home was damaged with windows blown out and roof damage. Several large trees were also downed along with 2 barns and 3 outbuildings destroyed. EPISODE NARRATIVE: A strong low pressure system over Minnesota pushed a front across our area. Very strong winds aloft set the stage for damaging wind gusts and tornadoes. Enough instability was present ahead of this front to enhance the severe threat. An area of severe thunderstorms and embedded supercells moved into the Piedmont of Virginia late in the evening of the 26th into early on the 27th. These storms produced areas of wind damage and two tornadoes.
