WINTER WEATHER ADVISORY in effect for all mountain passes through early Monday morning for accumulating snow and dangerous driving conditions. Continued snowfall through early Monday will add between 1 and 4 inches of new accumulation. Valley locations will see a trace to 2 inches of snow.
Scattered rain and snow showers will diminish by the afternoon. Cloudy to mostly cloudy skies with highs in the low to mid 30s. Areas of fog will develop for the Tuesday morning commute. Tuesday will be largely uneventful with a few light showers around the state.
Another system will impact Montana Christmas Eve and Christmas Day. Expect moderate snowfall for all valleys in the region. A colder air mass will arrive by the end of the week with temperatures only reaching the upper 20s by Friday. The best chance for snow will be in Kalispell on Christmas Eve and in Bozeman on Christmas Day. Missoula and Butte are pretty much even for snow chances on both days.
Colder air remains in place for the weekend with a slight chance for showers. More cold air could be on the way for early next week. Stay with us.
