The episode as NWS CLE wrote it up.
Severe thunderstorms tracked across northwest Pennsylvania during the evening hours on June 25th. Pennsylvania was located on the periphery of high pressure over the southeastern states. Moisture increased from the southwest around the ridge with dewpoints increasing to near 70 degrees. An unstable airmass developed during the afternoon as temperatures rose into the mid 80s with mixed layer CAPE values near 2000 j/kg. Energy moving through the flow aloft helped to initiate convection and provided the shear necessary for damaging winds across Crawford County, Pennsylvania. Numerous reports of downed trees and power lines reported across the county, especially in Linesville, Meadville, and Spartansburg.
