Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
352 AM MST Sun Feb 18 2018

DISCUSSION:
Unorganized snow bands persist over western Montana and much of
north-central Idaho this morning. As the arctic front continues
to drop into the area today, any remaining westerly winds will
likely transition to gusty north and east winds. The snow showers
will slowly move southward throughout today as the cold, drier
arctic air mass takes over the area. Temperatures will become
bitterly cold overnight and some blowing and drifting will
continue for western Montana, especially along the Divide. Light,
isolated snow showers should linger in the area through Monday and
Tuesday as we reside under a cold, northerly flow.
