First Alert 48 Hour Forecast

Monsoon moisture will begin to creep into western Montana this afternoon.  Moisture combined with instability will create the proper environment for thunderstorm development. The best location for thunderstorms will be south of I-90. However, all areas have an isolated chance.

A stronger surge of moisture will spark off showers and thunderstorms region-wide on Tuesday.

Showers and thunderstorms will continue to impact the region Wednesday, mainly afternoon around southwest Montana.

Temperatures fall back into the 70s and 80s late in the week with more wet weather possible next weekend.
