BOZEMAN – Get ready for a significant blast of winter like weather across the entire region Monday night through Wednesday night.

Snow and blowing snow are producing hazardous travel conditions for Monida Pass over to the West Yellowstone area and across Eastern Idaho. This area will continue to see snow and blowing snow conditions tonight through Wednesday morning.

A cold front will be the focal point of snow and wind to roll over western Montana Tuesday morning and push into eastern Montana by Wednesday morning. This front will bring increasing snow and wind to Butte late Tuesday morning into Tuesday afternoon. Bozeman look for rain ahead of the front Tuesday afternoon and changing over to all snow after sunset Tuesday. This could create extremely icy road conditions on Tuesday night and for Wednesday morning commutes.
