BOZEMAN – Much colder weather pattern over Montana this week. Temperatures Monday morning fell down around zero and even slightly below zero in Butte.
Temperatures will likely remain below normal for the rest of the week with a very gradual warming trend by the end of the week into the upcoming weekend.
Upstream is weaker Pacific storm system will push across the region from West to East tonight through Wednesday morning.
This system will produce scattered snow showers with the best chance for accumulations to be over mountains and passes but at times the lower valley floor could see a quick shot of off-and-on snow. This will keep area roadways wet to icy so plan on continued slow-go travel through Wednesday.
One of snow forecast models is hinting at 1”-4” of valley snow is possible tonight through Wednesday afternoon. But mountains in favored upslope areas along the MT/ID state line will have a much better chance for moderate snow accumulations at higher elevations.
If you are planning to travel west into northern Idaho or eastern Washington State there is a Winter Weather Advisory up tonight through Tuesday afternoon. Watch of wintry travel impacts with snow, cold, and wind.
