The episode as NWS RLX wrote it up.
Thunderstorms intensified during the late afternoon in central and southern Ohio, as a weak low pressure was moving across northern Ohio. A humid air mass existed in the mid Ohio Valley with surface dew points in the lower 70s. The storms moved into West Virginnia during the evening hours. A few locations got over 2 inches of rain, but the ground was relatively dry.
