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

An EF-1 tornado with a maximum estimated wind speed of 95 MPH identified by satellite data and confirmed by aerial survey. This tornado damaged mainly crops along its 3.4 mile long path. Towards the end of its path it destroyed a hoop building, removed a roof of a farm outbuilding and destroyed a garage at a residence. A woman was trapped in the garage as it collapsed around her.
