MISSOULA — We'll be approaching record heat this afternoon across western Montana as temperatures soar well into the 90s and low 100s. Missoula: 99°, Record: 101°. Kalispell: 96°, Record: 98°. The hottest temperatures will be found in the lower elevations along the Montana/Idaho border where areas like Troy, Trout Creek, Libby and Plains will range from 100°-to-107°.
Now with all this heat, a stray thunderstorms or two will also be possible for certain locations this weekend. Friday night southwest Montana will have a chance to see an isolated thunderstorm. Then Saturday afternoon and evening, northwest Montana around Kalispell, Whitefish and Glacier National Park may see a stray thunderstorm or two develop. However, for the most part this weekend will remain dry and hot with highs in the 90s and 100s.
90s remain in the forecast Monday. A cooler weather pattern will then set up Tuesday and Wednesday of next week as a dry cold front moves through. This will bring the first relief from the heat as highs drop back into the low to middle 80s Tuesday and Wednesday.
