High pressure will begin to shift east of Montana, allowing a cold front to enter the Pacific northwest. The front will slowly move east, moving into northwest Montana on Wednesday, bringing cooler air to the Kalispell area. In advance of the front, another warm day is expected in Missoula south and east to Butte and Bozeman. Increasing west southwest winds will gust up to 30 mph in some areas by late afternoon. The front will stall across southwest Montana Wednesday night and Thursday. This area will have the best chance of seeing a few showers and storms develop. This includes Butte and Bozeman. Much cooler Thursday with highs only in the 40s around Butte to the 50s elsewhere.

The cool spell will be very temporary. Another ridge of high pressure will build into the region Friday and over the weekend. This will bring sunny, warm days this Mother's Day weekend along with clear and cool nights.
