Snow is forecast for western Montana this week, with the chance of icy roads and low visibility. According to the National Weather Service, Missoula:
More snow is anticipated across the Northern Rockies Wednesday evening through Thursday morning. Most area mountain passes will be impacted by snow-covered and icy roads, as well as occasional low visibility in blowing snow. Valleys may also be impacted by snow at times, including sudden reduced visibility due to blowing snow in squalls as well as drastic changes in road conditions between locations. It's tough to say for certain where these narrow and intense snow bands will develop, but west central Montana in general has the best chance.
