WINTER WEATHER ADVISORY in effect for all mountain passes through early Monday morning for heavy snow and dangerous driving conditions. Continued snowfall through early Monday will add between 1 and 4 inches of new accumulation. Overnight lows drop into the upper 20s and low 30s.
Rain will gradually turn over to snow in most valleys outside of Sanders and Lincoln counties Monday, but only light accumulations are expected with showers being more scattered than they were over the weekend. Mountain snow will continue to pile up in Southwest Montana through late Monday. Highs top out in the low to mid 30s.
Tuesday will be largely uneventful with light showers around the state. Shower activity in Northwest Montana will spike as we head into Tuesday night.
Another system with much colder air behind it will impact Montana Christmas Eve and Christmas Day. Expect moderate snowfall for all valleys in the region with temperatures only reaching the upper 20s by the time the storm activity wraps up on Friday. Expect a better chance for snow 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.
