In the early morning hours of July 13 a line of thunderstorms that had developed over the eastern Dakotas moved southeast across Minnesota. Continued redevelopment of the storms as they passed through parts of east central and south central Minnesota led to significant precipitation totals of four or more inches resulting in numerous reports of flooding. The National Weather Service issued both Flash Flood Warnings and Flood Warnings for a number of counties from the Twin Cities metropolitan area south to the Iowa border.
The counties of Scott and Rice appear to have been hit the hardest especially the towns of Dundas and Northfield. The Cannon River, which passes through both Dundas and Northfield, rose quickly during the morning hours due to the heavy rainfall. The flooding river washed out roads and railroad tracks while also inundating homes along its banks forcing rescues and evacuations. The Cannon, Straight, and Vermillion Rivers and many of the smaller creeks and streams that feed into these systems were full or out of bank by the evening of July 13 and the morning of July 14.
Numerous precipitation reports of the event came in from law enforcement, trained spotters, and the public. A trained spotter measured 6.69 inches near Crystal Bay in Scott County, while outside New Market in Scott County, a report of 8.30 inches came from the public. The heavy rain was enough to break the daily rainfall record for July 13 for Minneapolis/St. Paul with 2.79 inches measured at the International Airport.
According to NOAA Atlas 14 Precipitation Frequency Estimates for Minnesota, a 24-hour rainfall total of 7.27 inches in that area has an average recurrence interval of 100 years. Phrased differently, the probability of a location in that area receiving a rainfall of 7.27 inches or more in a 24-hour period in a given year is one percent.
