tornadoes in Wisconsin

We usually have between 12 and 24 tornadoes in our state every year. Sometimes more. There were sixteen in the storms in four counties of east central Wisconsin last Tuesday. No serious injuries, as far as I know. This was the worst outbreak since 2005, when there were 25 in one day.
