The path drawn at its surveyed width of 50 yards (0.03 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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

Brief tornado went through mainly rural lands, but did hit a horse barn where farmers were actively feeding their horses. No injuries occurred, but a door blew in and nearly hit one of the farm workers.

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 Darien (42.5814, -88.7242).
