Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
448 AM MST Thu Dec 14 2017

DISCUSSION:

High pressure returns to high elevations of the Northern Rockies
through tonight, with relatively light winds and valley inversions
redeveloping.

A weak winter storm cycle will exist over the region for at least
the next week beginning Friday afternoon. Snow levels will be
just above valley elevations for much of the first system, with up
to 6 inches total accumulation at pass elevations through
Saturday. Wind gusts over 40 mph along the Continental Divide will
make backcountry travel difficult. The subsequent storm system on
Sunday- Monday will have similar snow and wind conditions along
Continental Divide as well.
