What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

Fifty to seventy-five oak trees of 1.5-2.0 feet in diameter downed. Tops of many other trees were snapped off.

The wider storm

A Quasi-linear convective system with a cyclonic rotating comma head on the north end produced numerous tornadoes and damaging straight line winds. Governor Walker declared a State of Emergency for Green and Dane counties due to the extensive damage from severe thunderstorms and tornadoes that occurred from June 16-18.

Began near Rewey (42.8128, -90.3535).
