Clear, cool nights and warm, sunny days through Friday.
High pressure remains in control through Friday. Ample sunshine with temperatures near normal for this time of year. Highs today and Friday will be in the upper 70s in Butte and Kalispell to the lower 80s in Missoula and Bozeman. Low temperatures will be cool. Lows in the 40s in Bozeman, Butte and Kalispell to the lower 50s in Missoula.
We are tracking a storm system that will impact the region Labor Day weekend. In advance of our next storm system, look for increasing cloud and a slight chance of a thunderstorm 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 of thunder 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 levels in Glacier will lower to 6000 feet, which means snow will be possible at Logan Pass. Tourists in Glacier National Park and Yellowstone National Park will need to be cautious of changing weather conditions this holiday weekend.
More unsettled and cool weather is expected periodically next week with below normal temperatures as we head through the first week of September.
