MISSOULA — We are looking at a hot and hazy day across the northern Rockies Monday.
Temperatures will top out in the upper 80s to low 90s. The one thing that may keep these temperatures a bit cooler, is the fact that smoke and haze along with increasing clouds will decrease solar heating.
Moisture will be pushing into the northern Rockies tonight into Tuesday leading to thunderstorm development.
These storms will be isolated in nature, and primarily found in southwest Montana. Some storms could become strong Tuesday afternoon with gusty winds, lightning, and even small hail possible.
Another round of thunderstorms will be possible Wednesday as high temperatures top out in the 80s. Smoky and hazy conditions could very likely remain in western Montana through the middle of this week.
Thursday, Friday and Saturday are shaping up to be sunny, warm and dry days as highs remain in the middle to upper 80s.
By Sunday, we are watching the potential for a pattern change across the northwest part of the United States as an upper-level trough dips south out of British Columbia and Alberta.
Now there are still a few key details to iron out. A further southward trajectory would bring a significant cool down with temperatures well below normal and increased odds for precipitation.
However, another scenario keeps the trough further north along the Canadian border. This would favor, cooler weather along with dry and windy conditions. Stay tuned!
