—————

We experienced heavy snow showers overnight around Lookout Pass, resulting in several inches of snowfall. Snow showers are expected to continue into the evening today with some additional snow accumulations at the passes.

Lows will be in the mid teens to mid 20s. West Yellowstone will even fall into the single digits tonight.

Tomorrow we still expect significant snowfall in the mountain passes, especially along the state line and Marias Pass. We could see accumulations of around 7 to 14 inches by Tuesday evening.

We will see strong winds in the upper elevations and less rainfall in the valleys.

As these winds weaken Tuesday afternoon into Wednesday, there may be an increased chance of wintry driving impacts across our valleys as temperatures continue to drop and snow showers continue.

We expect a ridge of high pressure across western Montana Thursday through Friday, potentially creating pools of cold air and inversions in the valley. Be prepared for possible fog and stratus formation.
