A large cluster of thunderstorms developed across northern Ohio ahead of a cold front and associated upper level low dropping south across the Great Lakes Region.  The airmass ahead of the front was moist and thunderstorms produced a combination of damaging winds, large hail, and flash flooding.  In Geauga County, heavy rainfall caused flash flooding from Bainbridge Township north to Novelty. Silver Creek came out of its banks in Novelty and flooded the Copaw Cabana Kennel where three people and 12 dogs had to be rescued around 4 pm. Another water rescue occurred on Snyder Road where a woman's car was moved by water. Rushing water entered the Chagrin Valley Roller Rink south of Chagrin Falls in Geauga County with rushing water of 3 to 4 feet deep on nearby Cedar and South Streets. Numerous roads were closed in Bainbridge including Ohio Route 306, Haskins Road, Snyder Road under 422, Bainbridge Road and East Washington. Tanglewood Lake overflowed and reached the secondary spillway, also flooding the Tanglewood Golf Club causing damage to at least 2 holes. Lake Lucerne Dam was in danger of breaching and water overflowing the lake reached homes downstream with numerous flooded basements. One observation from South Russell indicated 2.91 inches of rain fell, mostly between 1 and 4 pm with most areas receiving at least 1.5 to almost 3 inches of rain. Flash flooding also occurred in Chagrin Falls area of Cuyahoga County.  Water was flowing from upstream in Geauga County to the Chagrin Falls area and residents reported a 6-foot wall of water moved through the neighborhood and destroyed the wall of a walk out basement on Elm Court. Numerous other basements in the area were flooded. Several roads had to be closed due to the flooding. Rapid rises occurred on the Chagrin River with the water running swiftly and at high capacity.
