An upper-level disturbance approaching the lower Ohio Valley triggered a large thunderstorm complex that produced heavy rainfall. Although it was small-scale, the slow movement of this disturbance produced torrential rainfall of 1 to 3 inches over a few hours. Mean winds through the depth of the atmosphere were generally 5 knots or less to the north-northwest. Precipitable water values were above two inches, which is near the daily record.
