What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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

Tornado originated in northern Illinois and came across the border into Walworth county before ending south of Geneva Lake. Damage occurred to a couple of farm outbuildings.

The wider storm

A few rounds of strong to severe thunderstorms moved along a stationary front that was draped across southern WI. Two tornadoes occurred with the second line of storms in the early afternoon. One of those tornadoes tracked across the IL/WI border and hit a couple barns before it ended south of Geneva Lake. Both the second and third rounds of storms produced large hail and damaging downburst winds. Mostly tree damage occurred with the downburst winds. A couple reports of flooding on the Milwaukee interstate system was also received.

Began near Walworth Big Foot Ar (42.4949, -88.6430).
