The path drawn at its surveyed width of 25 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

Video from around 1/2 mile south of the Marion/Fayette county line shows a weak tornado to the north of a treeline along the county line. Just to the west of the tornado in that video, NWS storm survey found minor (EF-0) damage slightly north of the county line.

The wider storm

A convective complex moved through the region during the day on June 21st. Though it remained sub-severe for most of its life, the complex did intensify in south-central Illinois where it produced tornadoes, wind damage, and flash flooding.

Began near Vernon (38.8382, -89.1186).
