Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
415 AM MST Thu Dec 8 2016

DISCUSSION: Very cold temperatures and easterly breezes remain in
the forecast for today most everywhere. These breezes will
decrease in north central Idaho but remain at least through
Friday in western Montana. The first snow producing weather
system is still on track to bring moderate to heavy and light
density snow to the region tonight into Friday. Temperatures over
north-central Idaho and southwestern Montana begin to moderate
today but any real change in temperature will hold off until
Friday, and snow densities will become heavier on Friday. The
arctic air will be slow to erode over northwest Montana over the
weekend. Another arctic intrusion with more snow is expected
Sunday into Monday.
