Severe Weather & Widespread Flooding
A slow-moving stacked/deep and cutoff low pressure system moved into and subsequently stalled in the Ohio and Tennessee Valleys from the 18th through the 21st of May. This resulted in repeated rounds of heavy rain and training storms, which yielded multiple periods of heavy rain that moved over the same areas within a 72-hour period. Most of the heavy rain fell from late on the 18th through the 19th, with numerous reports of 4-5+ inches, with isolated higher amounts, both in Delaware/Franklin counties in central Ohio and Butler/Hamilton in southwest Ohio and Campbell/Kenton/Pendleton in northern Kentucky.
