Heavy rain fell across central and southern Minnesota on Saturday, August 3. Rainfall totals exceeding four inches were reported in portions of Stearns, Wright, McLeod, Carver, Sibley, Scott, and LeSueur counties. A small portion of southeastern McLeod county received over six inches of rain. Glencoe of McLeod county reported a storm total of 6.92 inches.

The rain moved across the state in two waves. In the first wave, a  cluster of thunderstorms moved east across central Minnesota during the late morning of August 3. A second  wave of heavy rain swept through many of the same areas during the evening of the 3rd. Reports of street flooding, basement flooding, and road washouts were common throughout  the affected area. The second wave of thunderstorms also generated severe weather in the form of large hail, strong winds, and a reported tornado in Sibley County. The rain slowly tapered off over central Minnesota during the early morning hours of the 4th, with some showers and thunderstorms persisting in south central Minnesota throughout the day on the 4th.
