The National Weather Service confirms the touchdown of damaging tornadoes in southwestern Wisconsin and northeastern Iowa Saturday.
Early reports indicate the tornado was an E-F-1 with maximum sustained winds of 100 miles-an-hour.
It was on the ground for almost seven miles in Grant County.
Local officials say the storm track was about a mile north of Potosi and damage was done to a house, several farms and trees, with small hail left covering the ground after it passed.
