Heavy Rain & Flooding

Clusters of showers and thunderstorms formed in the local area during the morning and early afternoon hours on July 13, in an environment that was nearly-tropical in nature. With surface dewpoints in the 70s and even close to 80Â°F at times, the strongest storms were able to produce very efficient high rain rates. Some of these storms trained, or travelled, over the same areas, resulting in periods of extremely heavy rainfall which lead to many reports of flooding and flash flooding, particularly in parts of central Ohio. John Glenn International Airport (KCMH) measured 3.11 inches for the day, with many other reports of 3-5 inches in the area. Parts of southwestern Ohio were also impacted by heavy rain and subsequent flash flooding.
