WATCH THE FORECAST VIDEO:
Monday, expect a cloudy day with high temperatures in the 40s and 50s. Winds will be lighter, around 5-10 mph with gusts up to 20 mph at times.
The Monday night through Wednesday period is somewhat unsettled as a series of weak waves and Pacific moisture move across the area. Precipitation is mainly focused along and west of the continental divide, but chances of rain are possible in Central/North Central Montana Monday night. Snow levels initially range from around 4000-6000 ft Monday night but gradually rise to mainly above 6000-7000 ft later Tuesday and Tuesday night. Measurable snowfall during this period is mainly limited to northern portions of the continental divide and Glacier NP.
The mildest temperatures are likely on Wednesday along with a brief dry and milder. Upper ridging amplifies before the next series of Pacific troughs move into the region Thursday through Saturday. Stronger winds and at lease mountain precipitation are predicted during that period, at this time.
