First Alert 48 Hour Forecast

Air Quality Alert: Smoke will continue to be a health concern through Friday and possibly the weekend.

Monsoon moisture is combining with surface heating to bring a few wet and dry showers and thunderstorms to southwest Montana, mainly from Butte and Bozeman south to the Idaho border.  Most of this will end Thursday evening.  Otherwise, clear to partly cloudy with areas of thick smoke.  Lows Thursday night in the mid 40s to mid 50s.  Partly sunny skies and smoky Friday with highs in the 80s.

A cold front will move into western Montana late Saturday.  In advance of it, one more very warm day with highs in the 80s.  Increasing south southwest winds with some gusts up to 25 and 35 mph.  Chance of a late day thunderstorm.

Breezy and cooler Sunday with highs in the 70s.
