First Alert 48 Hour Forecast

A storm system in Wyoming is combining with surface heating and moisture to provide western Montana with clouds and scattered showers and isolated thundershowers.  Most of this will occur before midnight.  Becoming partly cloudy with patchy fog.  Lows in the 40s.

Partly sunny Friday with a slight chance of a shower.  Highs in the mid 60s in Bozeman to the 70s in the Missoula, Butte and Kalispell areas.

Another storm system will bring another round of showers and afternoon thundershowers on Saturday.  Variable cloudiness with highs in the upper 60s and 70s.  A slight chance of showers Sunday with warmer temperatures.  Highs in the 70s to around 80.

We are tracking our next storm system that will arrive as early as Monday. Widespread thunderstorms are possible Monday and Tuesday. Unsettled weather will continue through next week with temperatures turning cooler.
