Pockets of minor flooding occurred following a heavy rainfall event. Rainfall rates increased the night of the 17th into early on the 18th as a mid level shortwave trough pushed southeastward into the Plains states and interacted with a warm front lifting|northward across the Ohio River Valley. A southwesterly 850 mb low level jet ramped up to 40 to 45 knots, and precipitable water values were very high for this time of year. General rainfall amounts averaged 2 to 3 inches in 24 hours.
