High Wind in Eastern Pondera and Eastern Teton, Montana

Multiple sensors measured gusts in excess of 58 mph, including AWOS station K1JM Juliett, which measured a 71 mph gust. AWOS K1HM Hotel and mesonet sensor DAHMT Dahlman also measured strong gusts.

A robust shortwave shifting eastward from the Pacific Northwest eclipsed the Northern Rockies during the day October 4. At the surface, a surface trough slowly increased in magnitude through the day before ejecting eastward as a surface low late afternoon. As the surface low pulled away, a strong cold front (Aided by 50-70kt winds within the first few thousand feet of the surface) swept across the region. Mechanical mixing allowed for multiple 70+ mph gusts to be realized at the surface, even with the front passing after sunset for most locations.
