It was a beautiful end to 2025 with partly to mostly sunny skies, dry conditions, and pleasant temperatures. The only negative about today’s weather was that there was some wind along the Rocky Mountain Front and along Highway 200.
If you will be celebrating the New Year outdoors tonight in central and north-central Montana, you are going to have great weather to do so. The temperatures at and before midnight will be in the mid to upper 20s, 30s, and low 40s in most locations. There will still be a bit of a breeze around this evening, but the wind will diminish as the night goes on. It is also going to be partly cloudy to mostly clear and dry tonight with just some patchy fog along the Hi-Line. Lows tomorrow morning will be in the mid to upper teens, 20s and low 30s.
The first day of 2026 will feature pleasant weather as an upper-level ridge remains in control of our weather. Tomorrow will be partly cloudy, with the cloud cover increasing from southwest to northeast as the day goes on. It will be dry during the day tomorrow, but a couple rain/snow showers are possible along the Divide and the Rocky Mountain Front during the evening. There is also going to be little to no wind in most locations tomorrow. Along the Hi-Line east of I-15, it is going to be chilly tomorrow as highs are going to be in the 20s and 30s. Elsewhere, it is going to be mild again tomorrow as highs are going to be in the 40s and upper 30s. There will also be some areas of fog around tomorrow morning along the eastern half of the Hi-Line.

Along the Divide, there will be some snow/rain around tomorrow night and Friday. In the lower elevations, little to no snow and ice accumulation is expected. In the mountains, a coating to 5 inches of snow accumulation is expected, with the highest snow amounts in Glacier National Park. Some of the mountain passes, including Kings Hill Pass, Marias Pass and Rogers Pass, may be slick tomorrow night and Friday. It is also going to be mostly cloudy to overcast tomorrow night and Friday.
