Event narrative

Several dozen trees and wires blew down in the Boyce area of Clarke County, including several onto vehicles. One tree blew down onto a car in the 11800 block of US-340 Lord Fairfax Highway, injuring the occupant.

Wider weather episode

A subtle remnant disturbance from prior day's convection over the Midwest amplified a pre-existing lee pressure trough, igniting numerous thunderstorms. Given the excessive hot, humid, and unstable environment, these thunderstorms were able to organize into clusters and lines despite a lack of stronger wind shear.
