What happened

The episode as NWS CLE wrote it up.

A stationary front remained stretched across the Upper Ohio Valley during the early morning hours of June 6th. This front kept a very warm and humid airmass over northwestern Pennsylvania. A rapidly deepening area of low pressure moved quickly east across southern lower Michigan during the evening hours of June 5th. This low eventually moved across Lake Erie during the early morning hours of the 6th. Showers and thunderstorms developed along the stationary front stretching east from the low. These storms eventually moved into northwestern Pennsylvania during the early morning hours of June 6th. One of the stronger thunderstorms produced a downburst which overturned a camper trailer and killed a man. The same thunderstorm later produced a tornado in western Erie County. A second line of showers and storms affected Erie and Crawford Counties around daybreak on the 6th. These storms developed ahead of a cold front trailing the low. A tornado occurred in Crawford County just after daybreak.
