Precipitable water was near record levels across the immediate region for this time, with a strong low-level jet interacting with a nearly stationary west to east boundary as several weak disturbances progressed northeast across the area. Three to seven inches of rain fell through the Vermillion River basin on September 18-20. A fairly rapid rise into minor to moderate flooding occurred as a result of several periods of heavy rainfall.
