Beginning today, parts of western Montana are entering a prolonged period of active weather which likely continues through the first week of October. This pattern will keep the area with persistent below average temperatures, valley rain/mountain snow showers and breezy conditions.
Wednesday's daytime highs will be in the 50s and 60s, potentially low 70s near Bozeman. Breezy afternoon winds 20-40 mph will be possible this afternoon and evening. Snow levels will drop to about 7000 feet, leading to snow in the higher elevations. The Mission, Swan and Whitefish Ranges and Glacier National Park could see a few inches of snow Wednesday night.
Widespread valley rain and mountain snow continues for the end of the week and weekend. Daytime highs will be below average in the 40s and 50s. Snow levels could drop as low as 5000 feet by Friday, bringing the threat of accumulating snow to pass levels. Mountain passes such as Lost Trail Pass, Homestake Pass, and MacDonald Pass could see travel impacts from accumulating snowfall.
