MISSOULA — Two systems will bring mountain snow and valley rain/snow to the northern Rockies this weekend.
The first system moves in Friday afternoon and will be the weakest of the two. 1"-to-3" of new snow will be possible in the mountains with just light rain/snow showers in the valleys.
Saturday will be a dry day with mostly to partly cloudy skies. High temperatures will top out in the 30s to low 40s.
The next system will move in Sunday. This will be a slightly stronger system bringing 3"-to-6" of snow to mountain passes along the Montana/Idaho border. Mountain peaks could see up to 10" of new snow. Valleys will have the chance to see light snow fall Sunday morning before warming temperatures change it over to a rain/snow mix. Once again very little to no snow accumulation is expected in the valleys.
Right now, next week looks to be mostly dry, however, colder air will start moving south out of Canada. High temperatures to start next week will be in the mid to upper 30s.
By the end of the week, the first round of cold air in quite sometime will be felt across the northern Rockies as high temperature drop into the 20s and low 30s by Thursday. This then looks to continue through the weekend and into the following week.
