WEATHER DISCUSSION: Widely scattered showers and thunderstorms have begun to pop up across North Central and Southwestern Montana and will continue through this afternoon and evening. Expect more below average temperatures, a little bit cooler than Tuesday with highs in the 50’s and lows in the 30’s and 40’s. Cloudy skies are expected through most of the region with winds on the lighter side, 5 to 10 mph with gusts up to 20 mph.

Moisture pushes in from the North thanks to a low-pressure system in Canada. For the most part, these showers will not be much of an issue today and will just bring beneficial rainfall, though a few rumbles of thunder and isolated wind gusts will be possible. Another factor with this system will be higher elevation snow fall which will likely be heavy and wet at times. There is some concern that this heavy wet snow will result in some tree and power line damage. Winter Weather Advisories (Purple) and Winter Storm Warnings (Pink) are in effect tonight through Thursday evening, mostly warning of high snow accumulations, possible gusty winds, and difficult travel. Winter Storm Watches (blue) will be in effect for Southwestern portions through Thursday night.
