Showers and thunderstorms fired up during the early evening hours of June 21st due to several factors. A frontal boundary was located along the Lake Erie shoreline and a cold front was located off to the west. High temperatures and high dew points were driven into the region as a result of the location of the fronts, in combination with an area of high pressure located over the southeastern United States. This highly unstable airmass gave way to severe thunderstorms, which entered the southwestern areas of Ohio around 6:30pm EST and tracked northeast across the state. The convection finally came to an end around 10:00pm EST.
