Backcountry Forecast for western Montana and north central Idaho
National Weather Service Missoula MT
406 AM MST Sat Jan 20 2018

DISCUSSION: Scattered snow showers will persist across the region
today, though accumulations are anticipated to be light. Showers
should decrease in coverage by Sunday morning as brief high
pressure builds in. Then, widespread light snow will move into
the area late Sunday into Monday. Breezy ridge-top winds will
begin from the southwest on Sunday, and slowly shift to be from
the west-northwest by Monday with colder temperatures.
Accumulating snowfall of 4-8 inches, locally higher, are forecast
during this period for the mountains of north-central Idaho and
northwest/west-central Montana.

A brief respite from widespread moisture is likely much of the
day on Tuesday, before another round of active mountain snowfall
and breezy ridge winds are forecast Wednesday through the end of
the week.
