WEATHER DISCUSSION: A Pacific cold front treks across the state overnight resulting in snow squalls impacting western Montana and temperatures running around 5-10 degrees colder on Sunday. Wind also ramps up as the front passes through. Gusts up to 60 MPH for the Rocky Mountain Front, up to 40 MPH for the rest of central and eastern Montana.
Model guidance is indicating lesser impacts from Sunday evening's system. A coating to 2 inches can be expected for lower elevations as mountains receive 4 to 8 inches of snowfall. Expect hazardous pass travel through Monday morning.
Another weak disturbance brings the threat of snow showers overnight Monday. Snow showers could put down another, quick coating to 2 inches throughout central and eastern Montana.
After a very mild January, long-range models are hinting at a major pattern change for the end of February. There is a high likelihood for colder than normal temperatures and above normal precipitation towards the end of January and beginning of February.
