WESTERN MONTANA -

Wednesday will be as low-impact as you can get in regards to the weather. Expect sunshine with fair-weather clouds in the afternoon.  Southwest Montana will see highs anywhere from 65 degrees all the way up to 70 in Beaverhead County. The Missoula and Bitterroot Valleys as well as Thompson Falls will see mid and upper 70s temperatures. Northwest Montana will hit the low to mid 70s. There is a slight chance of a shower or thunderstorm in Yellowstone today.

There are big changes in the coming days which will hopefully get us back on track in the rainfall department. A storm system is rushing towards us today from the Gulf of Alaska and will start to impact the region Thursday evening. At the moment, it looks like the best chance for thunderstorms will be west of the Continental Divide. As the storm approaches temperatures will soar into the 80s at lower elevations. There will be plenty of energy for storm development. Some of these storms could be of the strong variety with gusty winds and even small hail in addition to lightning.

Those storms will quickly move north Thursday night and bring rain along the Canadian Border. The best chance for meaningful rainfall at the moment appears to be in Glacier National Park.

Temperatures plummet on Friday as the storm sits overhead. Expect highs only in the 60s across the entire region through the middle of next week. Scattered showers will continue as well.
