The path drawn at its surveyed width of 10 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

A tornado briefly touched down in a field 3 miles northeast of Abingdon. Minor crop damage occurred: however, no structures were impacted.

The wider storm

A stationary frontal boundary extending from southern Michigan across north-central Illinois served as the focus for severe thunderstorm development during the late afternoon and evening of June 5th. A vigorous upper-level disturbance tracking across the Upper Midwest added extra wind energy to the atmosphere, allowing supercell thunderstorms to develop along the front. Eight tornadoes were spawned by the storms, mainly along a Galesburg to Eureka line. An isolated tornado formed further south across eastern Logan and western DeWitt counties as well. No injuries were reported.

Began near Eastside Galesburg (40.8345, -90.3554).
