First Alert 48 Hour Forecast

Two more very nice summer days are expected across western Montana.  Clear, cool nights and warm, sunny days through Friday.  Lows in the 40s in Bozeman, Butte and Kalispell to the lower 50s in Missoula.  Highs Thursday and Friday in the upper 70s in Butte and Kalispell to the lower 80s in Missoula and Bozeman.

We are tracking a storm system that will impact the region Labor Day weekend. A few clouds will start moving into the region Friday in advance of the next storm system. There will also be a slight chance of thunderstorms late Friday.  Gusty winds will develop Friday and continue through the weekend.   There is a chance of thunderstorms Saturday as a cold front moves through the region.  The best chance will be across southwest Montana around Butte and especially Bozeman.  A few showers are possible Sunday and Labor Day, although rain chances have diminished.  Highs will drop to the 70s Saturday and the 60s Sunday and Monday.  Snow will be possible in the highest elevations, so tourists in Glacier National Park and Yellowstone National Park will need to be cautious of changing weather conditions this holiday weekend.  Snow levels in Glacier will lower to 6000 feet, which means snow will be possible at Logan Pass.

More unsettled and cool weather is expected periodically next week with below normal temperatures as we head through the first week of September.
