NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. 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

Tornado near Benchland at 510 PM. Classified as an EF0 Tornado with a peak wind estimated between 75 and 85 MPH. It was 400 yards wide and was on the ground for about a quarter of a mile. The tornado lifted near 515 PM.

The wider storm

A line of showers and thunderstorms develop east of the Southern Rocky Mountain Front and move northeastward across the area. These storms move into a moist environment with good jet dynamics, wind shear, and instability. As a result, a severe thunderstorm watch is issued for most of the CWA. The primary thunderstorm threats are severe hail of equal to or greater than quarter size and wind gusts of up to 60 to 80 mph. Heavy downpours of rain are also expected.

Began near Benchland (47.1000, -109.9800).
