The holiday weekend started out sunny, but it won’t stay that way. Snow has already begun moving through Montana as of Friday morning and will continue this evening through Saturday. A WINTER WEATHER ADVISORY will go into effect tonight for southwestern and central Montana, and a WINTER STORM WARNING will begin this evening as well for western Montana along the Idaho border. If you’re traveling this weekend, it’s going to be snowy on the roads, especially over mountain passes. Sunday, the snow will be out of here but could stick around on the roads.
