A wave of moisture is moving through western Montana Tuesday evening. It will bring high cloudiness to the region overnight. There is a chance of a brief sprinkle or shower in the Butte and Bozeman areas. Otherwise, the cloud cover will keep low temperatures mild, with lows in the mid 40s in Butte and Kalispell to the lower 50s in Missoula and Bozeman.
A very warm summer day is expected Wednesday. Partly sunny with a slight chance of an afternoon shower across southwest Montana. Otherwise, highs in the upper 70s in Butte to the 80s elsewhere.
A wave of moisture from a California storm will interact with a cold front Thursday bringing us the best chance of a shower or thunderstorm area wide. Highs in the 70s. Cooler with a slight chance of a shower Friday with highs in the upper 60s to lower 70s.
The weekend is looking very nice, with partly to mostly sunny skies. Lows in the mid 30s to mid 40s with highs in the 70s. A little warmer early next week.
