Active weather will return to the region this weekend into early next week. Stay up to date with the latest forecast if you have outdoor or travel plans during this time.

Strong crosswinds gusting to 45 to 60 mph will affect the foothills west of Billings beginning tonight and continuing into Saturday. The highest gusts likely will occur in the Livingston area, where there is an 80% chance of gusts reaching 50 mph, followed by Big Timber and Harlowton.

Heavy snow will affect the Beartooth/Absaroka and Crazy Mountains this weekend. Greatest snowfall amounts will occur on west- and southwest-facing slopes. Through Sunday, a large portion of these mountains will receive more than 8 inches of snow, with some locations receiving 12” or more of snow. Strong winds will cause blowing snow and contribute to difficult backcountry conditions. Additional snow is likely Sunday night into next week.

Chance of 2 or more inches of snow Saturday night through Monday night. Best chance is where upslope, northeasterly winds develop. Additional snow is possible after Monday night, but more uncertainty remains with that period.

Chance of 6 or more inches of snow Saturday night through Monday night. Best chance is over the Beartooth/Absaroka and Crazy Mountains. Additional snow is possible after Monday night, but more uncertainty remains with that period.
