BOZEMAN – Arctic High-pressure is finally weakening over Montana today and a slow warming trend should continue throughout the rest of the week.

Glasgow finally warmed above zero today ending 230 hours of subzero temperatures. The coldest morning lows for SW Montana are as follows: Belgrade –29 below zero on Saturday Feb. 13th, Bozeman MSU –22 below zero on Feb. 13th, Dillon –16 below zero on the 10th and 11th, West Yellowstone –20 below zero on the 10th and again on the 14th, Butte –13 below zero on the 12th.

Temperatures will slowly climb daily this week but are likely to remain below average.

There are several Pacific storms to clip western and southwestern Montana through mid-week producing several rounds of off and on snow with greatest accumulations for mountains and passes and minor accumulations for most valleys.

This will create some hazards with snow covered and icy roads, localized areas of blowing snow through Wednesday. Greatest concerns are for those mountain passes closest to the Montana and Idaho state line.

The National Weather Service has issued a WINTER WEATHER ADVISORY through 5 pm Monday west of the divide and through 5 am Tuesday east of the divide in SW Montana.

Butte/Blackfoot region can see 1”-4” of snow with up to 10” possible around Georgetown Lake, Highway 12 Garrison to Elliston, Homestake pass, and MacDonald pass.

East of the divide SW Montana could see valley snow around 1”-3” with 2”-5” for most mountains and passes. This includes Bozeman pass, Monida pass, Big Hole pass, Wisdom area, Norris Hill, Boulder Hill.

Livingston to Billings look for snow and blowing snow to produce hazardous travel impacts through Tuesday morning.
