A ridge of high pressure will continue to bring us very warm days and clear, chilly nights. Highs will warm into the 80s Tuesday and Wednesday. A weak storm system southwest of Montana will bring some mid and upper level moisture northward into western Montana. This moisture will combine with afternoon heating to bring a slight chance of isolated thunderstorms to areas south of I-90. With the lower levels very dry, little rain is expected. However, locally gusty winds are possible with these storms.
A Pacific storm system will move through the region Thursday and Friday. It will cool temperatures back to the normal 60s with a few showers. The best chance of rain will be over southwest Montana around Butte and Bozeman. A ridge of high pressure will then build back into the area by Sunday and Monday with a return of very warm weather.
