The path drawn at its surveyed width of 20 yards (0.01 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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

Short damage path through a forested section along Stone Church Drive.

The wider storm

One of the bigger tornado events for southern WI over the past 10-15 years with 2 EF-2s occurring and 8 tornadoes in total. Juneau and Mayville took the brunt of the two strong tornadoes, while hundreds of large hail reports and several damaging wind reports were received across southern WI. A strong cold front, extending from strong low pressure over eastern North Dakota, combined with very unstable air and strong wind shear to bring widespread severe thunderstorms to the region.

Began near La Rue (43.4307, -89.9453).
