We can expect one more warm summer day before autumn like weather settles into western Montana this holiday weekend.
A weak wave of moisture will move through western Montana Thursday night, bringing the threat of a few showers north of Kalispell to the Canadian border and also across southwest Montana from Butte and Bozeman south to the border. Otherwise, partly cloudy Thursday night with lows in the 40s.
Partly to mostly sunny Friday. Breezy with highs warming into the upper 70s to lower 80s.
A strong cold front will move through the region Saturday, bringing gusty winds and cooler temperatures. A chance of showers and thunderstorms around Bozeman and Butte with a slight chance in Missoula and Kalispell. Highs in the mid 60s to around 70. Partly sunny and cool Sunday with highs in the 60s. A slight chance of showers both Sunday and Labor Day on Monday.
Temperatures will warm back to the 70s Tuesday and Wednesday of next week with partly sunny skies.
