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

Public reported, via Facebook, video and photos of a tornado with debris at the surface visible. Visual evidence of a nearby power pole damaged and damage to a wind break made of metal and wood. Time is estimated by radar. Path length is estimated from storm survey.

The wider storm

A storm rapidly developed in Saskatchewan, turned right and tracked southeastward into Montana. The storm spawned a couple other storms that would track east-southeast across Montana counties that border Canada. Funnel clouds, tornadoes and large hail were generated with these storms.
