A mesoscale convective system developed overnight in South Dakota and traversed across Central Minnesota. The system continued into West Central Wisconsin, producing severe wind and hail.
The combination of large hail, strong winds and torrential rainfall, caused some crop damage, especially in Polk County where damage was extensive to their soybean crop.
A report stated that in St. Croix County in the village of North Hudson, there were sustained damages from straight line winds. Due to the damages, the village signed an emergency declaration for clean up. Six homes were evacuated due to a gas leak. There were other reports of minor or major damage to homes and businesses due to fallen trees, but no injuries were reported.

A report indicated that in Chippewa County, hail was large enough in the Town of Auburn (near Bloomer) that it damaged a couple homes.   One county road was blocked due to downed trees.
