Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
339 AM MST THU DEC 25 2014

DISCUSSION: Snow will be on the decrease through Thursday morning as
drier air works into the region. A weak disturbance is expected to
move through the area late Thursday night into Friday, especially
for north central Idaho. Moisture with this feature is lacking so
additional snow accumulations are expected to be light.

The next weather system of significance is expected for Saturday
into Sunday. This next system is looking to be another good snow
producer for both mountains and valleys, possibly even more so
than the Christmas Eve storm. A colder airmass will work its way
into the region beginning Sunday, allowing snow ratios to
increase. Along with this colder airmass, gusty northeast winds
are expected to develop, especially in western Montana Sunday
afternoon and evening. Much colder temperatures are anticipated by
next week.
