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 75 mph touched down in Lake County, moved across Jasper County, then crossed the Kankakee River and into Porter County just east of Baums Bridge Road. High resolution satellite imagery showed concentrated damage to numerous trees just after crossing the river. The tornado continued for a short time then ended south of Crooked Creek, south of County Road E 1050 S.
