Scattered showers and thunderstorms developed south of a stalled frontal boundary that was draped from NW to SE across southwestern Pennsylvania. A small line of storms formed over the Pittsburgh area and pushed SE across Somerset and Bedford County.  These storms produced considerable wind damage along the Route 30 corridor in Somerset County, but the wind damage quickly diminished as the storm continued eastward into slightly more stable air east of the Allegheny Front in Bedford County.
