Event narrative

The ASOS at the Southwest Wyoming Regional Airport reported a peak wind gust of 68 mph.

Wider weather episode

An upper-level disturbance moved across Wyoming, leading to the development of showers and thunderstorms. Very dry conditions at the surface within a hot airmass generated large dewpoint depressions. As a result, dry microbursts and strong outflow wind occurred ahead of showers and thunderstorms, primarily across Fremont and Sweetwater counties. Winds gusted as high as 68 mph at Southwest Wyoming Regional Airport near Rock Springs and 60 to 65 mph in the vicinity of Lander and Riverton.
