The path drawn at its surveyed width of 125 yards (0.07 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 brief tornado dropped in Union Township along W County Road 350 N just west of N County Road 650 W a couple of miles northwest of Shorewood Forest. It would track just over a half a mile to the east-southeast before lifting soon after crossing N County Road 625 W. Minor damage was noted to trees, outbuildings, and some farm equipment.

The wider storm

During the afternoon and evening of the 31st, a wave of severe thunderstorms produced numerous tornadoes, severe hail, and extensive wind damage across northwestern Indiana. A total of 23 tornadoes were confirmed across the state. The NWS Chicago office tied a record for the most tornadoes to occur in a single calendar day within the office's county warning area with 22, 5 of which occurred in Indiana. Two EF-2 tornadoes occurred in Benton County and one other in Lee County, Illinois. Some of the more notable damage includes a few homes with walls and portions of roofing blown away, a wind turbine that had been snapped in half, and wind turbine blades thrown as far as 600 yards, all a result of the two EF-2 tornadoes in Benton County.

Began near Sedley (41.4853, -87.1956).
