| 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 local law enforcement officials reported a tree blown down and blocking 10th Street, west of County Road 35, or approximately two miles south of East Farmington, Wisconsin. |
