A Canadian cold front will sink south into northern Montana by late this afternoon, stalling around the Kalispell area into central Montana.  This front will drag a cooler airmass over far northwest Montana, especially around Glacier Park.  Showers and t-storms are possible in today in Kalispell and around Bozeman and Butte, just a slight chance around Missoula.  Highs in the upper 70s in Kalispell and Butte to the lower 80s in Missoula and Bozeman.

The front will gradually move through the rest of the area Thursday and Friday. Highs Thursday, will be in the upper 60s in Kalispell and Butte to the 70s in Bozeman and Missoula. By Friday, we look for highs in the 60s to around 70. The weekend will be fall-like with highs in the 50s and 60s on Saturday. Low temperatures Sunday morning will be in the 30s and 40s!!  Along with the cooler temperatures, expect occasional showers.
