Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
352 AM MST SUN DEC 28 2014

DISCUSSION: A significant winter storm will continue across the
region today with periods of moderate to heavy snow through this
morning, then snow will become showery by this afternoon. An
arctic front will usher in a much colder airmass across far
northwest Montana early today working progressively southwestward
reaching north central Idaho by early Monday. Snow ratios will
increase to 25:1 in this colder airmass, causing snow to become
increasingly light and fluffy. Gusty northeast to east winds of
20-30 mph will also develop behind the arctic front, especially
for western montana this afternoon through Monday. Very cold
temperatures will dominate the first half of the coming week, with
low temperatures reaching well below zero.
