Yesterday the mountains near Bozeman and Big Sky got 1-2” of low density snow. Today you probably want a couple extra warm layers with the arrival of arctic air. This morning, temperatures range from below zero to low teens F, and wind is northerly at 5-15 mph with gusts to 25 mph. Near West Yellowstone wind is 15-25 mph with gusts to 35 mph. Today skies will be partly cloudy with less than a half inch of light snow falling. Temperatures will reach teens F with north-northeast wind at 5-20 mph.
