Following further evaluation of damage east of Evansville, the National Weather Service determined that the Evansville-Lake Koshkonong tornado had peak winds of 130 m.p.h.

The tornado was on the ground in Rock County, just south of Madison, for roughly 24 miles, passing just north of Edgerton and traveling north of Lake Koshkonong.

Just 30 minutes earlier, a separate tornado touched down and was on the ground for roughly eight miles, ending near Albany.

Only one person was reportedly taken to the hospital.
