One mobile home was overturned. Otherwise, only minor structural damage was noted, mainly limited to shingles blown off of roofs or siding damaged as tree limbs fell against houses.

This tornado dissipated over extreme eastern Westmoreland County, just before reaching the Somerset County line.
The Pittsburgh radar (KPBZ), 82 km away, was scanning. The volume nearest the first event began at 22:52 UTC.
