A weak trough was located across northwestern Ohio during the afternoon and evening hours. A moist, but marginally unstable atmosphere allowed for thunderstorms to develop and remain relatively stationary over the same areas. Local rainfall amounts of 2 to as much as over 6 inches fell across mainly Allen County, resulting in flash flooding. The flash flooding resulted in a small portion of Int...
Flash Flood — May 14, 2011
A weak surface trough and low pressure system tracking along it allowed for thunderstorms to develop across portions of northwestern Ohio. Weak flow parallel to the trough allowed for redevelopment of thunderstorms, producing rainfall rates of one to two inches per hour. This caused areas of flooding and flash flooding. No injuries were reported.
