Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
343 AM MST Fri Nov 24 2017

DISCUSSION: Everything is still on track for snow levels to lower
to at least 4000 feet today into Saturday, though this won`t last
long. A warm frontal feature will move north across the region
late Saturday, spreading light and continuous snowfall across
central Idaho mountains into the Kootenai/Cabinets. Snow levels
will bounce back up to the 6000-7000 foot range during this time.
Following close behind will be the cold front, expected Sunday
night through Monday, and will drive snow levels back down to 2000
feet. All this fluctuating will come to somewhat of a halt
thereafter, as the region looks to stay in a longwave troughing
pattern conducive for snow to occur in all the proper places (ie:
no more rain above 5000 feet).


Elevations above 4,000 FT:
