Episode Narrative Thunderstorms began to develop across portions of southern Minnesota the night of August 7th before midnight. A strong low level jet and deep moisture advection caused several waves of thunderstorms to develop along a line from near Hutchinson Minnesota, to the southern Twin Cities metro area, and into portions of west central Wisconsin. Two to four inches of rainfall was common in a 6 hour period, with locally four to six inches in a narrow band from the southwestern portions of the Twin Cities to portions of West Central Wisconsin, from Prescott to Eau Claire.
Event Narrative The River Falls Airport recorded 5.52 inches of rainfall, and most of it fell between midnight and 7 am.
