The path drawn at its surveyed width of 30 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

There were multiple reports of a tall, non-supercell (aka landspout) tornado to the north of Marbleton. The tornado remained over open country and caused no known damage.

The wider storm

An upper level shortwave moved over Wyoming, accompanied by a jet streak. The surface dew points remained low, resulting in large dew point depressions. The result was many severe thunderstorms that produced wind gusts in excess of 58 mph.

Began near Marbleton (42.6319, -109.9843).
