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

A tornado briefly touched down in a field. No damage was reported.

The wider storm

A nearly stationary, west to east oriented, frontal boundary wobbled north and south across northern and central Illinois during the afternoon hours of the 21st into the early morning hours of the 22nd. The movement of the front was largely modulated by outflows from various thunderstorm complexes. A few of these storm complexes developed over or moved across central Illinois. One complex produced two weak tornadoes and several funnel clouds as it developed over east central Illinois during the early evening. Other storms produced damaging wind gusts, heavy rainfall, and small hail.

Began near East Lynn (40.4800, -87.8089).
