BUTTE Mont: – Strong cold front will hit Montana Thursday evening through Friday evening. This storm will pass through Montana from North to South and drag in much colder Canadian air by Saturday morning.

Hi-line areas will be impacted first by early Friday morning and Southern Montana by late Friday morning.

Early Friday morning locally lower valleys could see a rain/snow mix and as the front passes through change over to all snow by Friday afternoon. The front will likely produce gusty winds as the front passes through and could create reduced visibility with falling snow.

Snow will likely diminish Friday night but as skies clear temperatures will be much colder by Saturday morning keeping all area roadways icy.



The National Weather Service has a “WINTER WEATHER ADVISORY” up for our region Friday morning into early Saturday morning.

Snow accumulations: Valleys 1″ – 3″ is possible. Mountains and passes 4″ – 8″ is possible.

Wet roads will become icy at all levels and will impact your Friday evening commute.


Traveling to Missoula will become tricky Friday as this storm system drops through the state. Periods of snow, wind, low visibility and wet slushy roads turning icy is likely for I-90 and I-15 Friday. If you plan on traveling to the game early Saturday morning watch for icy roads and ice or black ice for bridge decks. Regardless what day you travel plan on adding extra time to get to Missoula.
