In the early morning hours of June 23, a cluster of thunderstorms developed over Lake Erie. These storms moved ashore off of Lake Erie around 4am with extensive tree damage to the immediate lake shore counties around the Cleveland metro area. Damage was reported in Avon Lake and Madison. The ASOS at Burke Lakefront Airport also reported a wind gust of 52 mph. Shortly thereafter, a residual line of thunderstorms moved across Lake Erie onto the lakeshore.

The area impacted from the first round of thunderstorms from Avon Point to Geneva was also impacted by this next round. Eastlake had the worst damage from these storms as over 30 large trees were knocked down with several trees landing on homes, businesses, and vehicles.

Many of these communities had 2 inches of rain in 2 to 3 hours.
Heavy rainfall of 1.5 to 2.5 inches of rain fell across mainly central Mahoning County during the morning of June 23rd.

Bay Village received between 2.8 to 3.5 of rain during about a two hour time period which resulted in over 400 homes with basement flooding.
