A strong winter system is moving its way into the northern Rockies and high elevation areas of southern Montana could see up to 20″ by Saturday reports NOAA.
“Heaviest snow looks to be Thursday night into Friday, but there will be periods of snow in the high country from tonight through Friday night.” – NWS Billings
Further south, the Tetons should also pick up some snow– albeit not as heavy as their northern neighbors. For those traveling, expect major Yellowstone thoroughfares to be closed throughout the weekend. Beartooth Pass is currently closed and will remain so until further notice.
