The episode as NWS IWX wrote it up.
A slow moving low pressure system tracked northeast along a quasi-stationary boundary, bringing widespread showers and thunderstorms to northwest Ohio during the early morning hours of July 9th. Showers and thunderstorms were very efficient rainfall producers, with reports of 3 to 4 inches of rainfall reported in Van Wert county. This, combined with saturated ground conditions from previous rainfall, allowed for widespread areal flooding across Van Wert county.
