Yellowstone National Park will continue to get hammered with snow and gusty winds until Saturday morning with a Winter Weather Advisory. Up to 12" of fresh snow could fall and visibility may be near zero during this time.
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.
