Event narrative
Ambient weather station Buckskin measured a 65 mph gust. Trained spotters in a nearby area (Different zone) reported gusts to 70 mph.
Wider weather episode
An upper level ridge across the Northern Rockies was flattened by a potent shortwave over Dec 6-8 timeframe. Initially stout zonal mid-level flow was aided by a strengthening pressure gradient to result in quite a few strong winds gusts over the multi-day period. Adequate moistures resulted in locally heavy snow along the Rocky Mountain Front and into Central Montana by Dec 9.
