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 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

Weak tornado started on the southeast end of Geneva Lake and went through the southeast side of Lake Geneva. Mainly tree damage along the path, but some minor structural damage in the business district bounded by highways 120, 50 and 12. Path appeared to end just south of the Grand Geneva resort.

The wider storm

A line of severe thunderstorms ahead of an approaching cold front brought two tornadoes, flash flooding, and straight-line wind damage to far southern WI.
