Between May 25th and May 26th heavy rainfall occurred as a warm front lifted north across the area. A strong southerly flow, ahead of a cold front, transported very moist air through Tennessee, Kentucky and into Ohio on the 25th. Surface dew points were in the 60s. Wave after wave in the mid and upper levels helped trigger widespread showers, with embedded thunderstorms. High rainfall rates of over an inch per hour occured with the stronger storms, resulting in widespread flood warnings across Northern Ohio. The showers continued into the evening hours, and then reformed early on the 26th. By this point the ground was saturated and streams and creeks were running high. Additional storms compounded lingering flooding conditions, necessitating a second round of widespread flood warnings. Numerous state and local routes in the area were closed because of the quickly rising and flowing water.
