The episode as NWS CLE wrote it up.
During the evening and nighttime hours on June 4th, an area of low pressure tracked east from Lake Erie to Lake Ontario. The trailing cold front was oriented east-west right along the Lake Erie shoreline. As the low pressure center continued to move to the north and east, the frontal boundary continued to linger across northern Ohio. Showers and thunderstorms fired up along and near the boundary during the overnight/early morning hours of June 5th.
