Event narrative
Wunderground sensor Upper Elk Creek KMTAUGUS3 measured a 58 mph gust.
Wider weather episode
A splitting trough resulted in a period of heavy snow across the high terrain of Madison and Gallatin counties late Oct 17 into the 18th. Further, as the trough pulled away, a secondary wave diving SE from BC resulted in strong cross barrier flow, ridgetop stability and hence strong wind gusts across the plains adjacent to the Rocky Mountain Front. A strong pressure gradient also helped stronger gusts occur near the Rocky Mountain Front.
