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

Several hundred yards of large trees down, and cars rolled over. A chimney removed from a home, and roof damage to a small shed.

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 Mineral Pt (42.8208, -90.2636).
