High Wind in Snowy and Judith Mountains, Montana

Mesonet station JPKM8 Judith Peak RAWS reported a 70mph wind gust.

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.
