Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
345 AM MST Thu Feb 23 2017

DISCUSSION: A cooler and unsettled weather pattern will persist
through the end of the work week as a large scale upper level
trough remains over the region. Precipitation will be showery in
nature, with snow levels generally expected down into the valleys.

Two waves of energy will bring a better potential for widespread
snow accumulations this weekend, one on Saturday and a second
stronger system on Sunday. Snow levels will continue to bring snow
down to the valley floors.
