The National Weather Service in Great Falls has issued a Winter Weather Advisory for most of central Montana through Monday morning.
The advisory means wintry weather is expected, which could create travel difficulties.
STORMTracker meteorologist Mike Rawlins says 1-3" of snow is expected, which will make roads slick.
Drivers should be prepared for winter driving conditions and allow plenty of extra time to reach their destination.
Light snow is expected to fall through the evening hours, tapering off slowly after midnight in most areas.
Some areas will still see light snow through Monday morning, but significant accumulation is unlikely on Monday.
