The path drawn at its surveyed width of 40 yards (0.02 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 rancher reported a brief touchdown of a tornado north of Kaycee to the Johnson County Sheriffs office.

The wider storm

An upper level low passing over Wyoming combined with a strong jet stream to bring an outbreak of severe thunderstorms. Four tornadoes were reported on this day, the most in one day since June 12, 2017. There was one each in Johnson and Sweetwater County and two in Natrona County. The largest tornado was south of Midwest in northern Natrona County where a horse trailer was flipped and fuel tanks were blown away. Very large hail also occurred with some of the storms. The largest hail occurred in southern Johnson County and northern Natrona County where baseball size hail was reported. Another severe thunderstorms moved from Lander to Riverton and dropped quarter to golf ball size hail, causing damage to many vehicles.

Began near Kaycee (43.7345, -106.6500).
