What happened
The episode as NWS CLE wrote it up.
Showers and thunderstorms entered northwest Pennsylvania during the early evening hours on the 29th. A frontal boundary oriented west-east along the southern Great Lakes aided in the development of the severe weather. High dew points, warm temperatures, and high instability along and near the frontal boundary also supported the development of severe thunderstorms which tracked east across northwest Pennsylvania that evening.
