Another round of significant snow is headed for the mountains near the Montana/Idaho border, with up to a foot or more possible by Friday night. This Winter Weather Advisory will probably only bring a few inches of snow to lower elevations.
Southern mountains of Gallatin, Madison and Beaverhead Counties may get up to a foot of fresh snow by Tuesday morning. Gusty winds up to 60 mph are also possible, creating difficult travel conditions over mountain passes.
Southern Gallatin and Madison counties continue to get lots of snowfall and the Winter Weather Advisory now continues until 5am Saturday morning with several more inches of fresh snow possible.
Be patient. It's coming eventually. HWY 20 out of West Yellowstone (headed to Targhee Pass) is getting much needed lane safety improvements...starting in 2023.
Southern Madison and Gallatin counties could see 5" or more above 6500 feet by mid-day Saturday. Slippery roads may be an issue if you're traveling south to Idaho.
