The path drawn at its surveyed width of 250 yards (0.14 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

A tornado with estimated peak winds of 80 mph touched down near Jefferson Avenue and 2nd Street. The tornado moved northeast through southern Watseka and ended near the intersection of Route 1 and Route 24. Damage along the path was largely confined to downed tree limbs.
