BOZEMAN – A stormy pattern for the next couple of days across most of the western half of the country. There is a powerful Pacific storm over California, a cold front pushing into Eastern Montana, and a weak upper-level Low over the Gulf of Alaska.

The storm over California will migrate to the NE and begin to push warm and very moist air up into Idaho, Wyoming and Montana beginning Tuesday night through Thursday morning.

Mountains and passes will have a high probability of seeing periods of snow, heavy at times, and gusty surface winds. Lower valleys could see a rain-snow mix with accumulating snow in the colder overnight hours.

This will create difficult travel conditions to hazardous travel conditions through Thursday late morning.

The National Weather Service continues a WINTER STORM WARNING for most mountains and pass across SW Montana up into central Montana through 6 am Thursday.

Snow accumulations of 10”-20” is possible with peak wind gusts around 55 mph.
