What happened

The episode as NWS RIW wrote it up.

Downsloping and gradient winds provided gusty conditions in association with deep low pressure over western Canada. The strongest winds were recorded in eastern Fremont and western Natrona counties where automated stations measured peak gusts of 77 mph and 67 mph, respectively. Other impacted locations from Powell to Rock Springs, including Cody and Dubois, commonly observed peak gusts of 60 to 65 mph. A small wooden hangar at the Dubois Airport was flipped one-quarter turn from its foundation and came to rest on an airport road. Another hangar at the airport sustained minor damage. In the lee of the Bighorn Mountains, the highest wind gust of 60 mph was recorded in Buffalo at the Johnson County Airport.
