The path drawn at its surveyed width of 30 yards (0.02 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

This brief, weak and narrow tornado began just west of Osseo where it touched down at Merchants Baseball Field off US Highway 10 where it destroyed a storage garage and caused tree damage. The tornado caused additional damage off W 5th Street near Spruce Road where a couple sheds, trees, and a power pole were damaged just prior to the tornado dissipating.

The wider storm

During the evening hours on June 19th, a couple of severe storms produced large hail, damaging wind gusts and two brief tornadoes. One of these storms trekked through Trempealeau County where it produced golf ball sized hail in Osseo as well as a weak EF-0 tornado which resulted in minor damage. An additional tornado was documented in Jackson County, but no damage was verified which resulted in an EF-U rating.

Began near Osseo (44.5817, -91.2437).
