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

This short lived tornado began 2 miles northwest of Detroit, IL, along 435th street. Damage was primarily confined to trees, but there was a home with roof damage and a large camper was blown on its side. Overall, the tornado was rated EF0 with a path length of 0.11 miles and a max path width of 25 yards. No injuries or deaths were reported with this tornado.

The wider storm

By late morning much of the rain shifted north and east of forecast area allowing partial

clearing to destabilize the atmosphere. Steep lapse rates due to relatively cold mid level temperatures southeast of the upper level low combined with strong low-mid level wind shear due to an 80-kt mid level wind max southeast of the upper level low. This led to the development of isolated low topped supercells along the northward moving warm front and ahead of the eastward moving cold front. Eight tornadoes were surveyed over WFO LSX's forecast area.

Began near Detroit (39.6319, -90.7143).
