Cold air has invaded western Montana. We can expect below normal temperatures as February comes to an end and we enter the month of March. Partly cloudy Thursday night with a slight chance of a flurry or snow shower along and south of I-90. Lows in the single digits in Bozeman and Butte to the 10s in Missoula and Kalispell.
A surge of moisture will move into southwest Montana Friday. There will be a chance of flurries and snow showers, again, mainly along and south of I-90, including Bozeman and Butte. Highs in the 20s in Bozeman and Butte to the 30s in Missoula and Kalispell.
Another surge of cold air will bring a few flurries and isolated snow showers to the region Saturday. Dry but cold Sunday. Lows will drop below zero in Butte to the single digits above zero to around 10 elsewhere.
Models are indicating another surge of arctic air will move into the area Monday night and Tuesday. Windy with snow Monday night.
