...Prolonged Active, Breezy Pattern with Minimal Breaks in
Precipitation this Week...

Persistent light to moderate snow will continue for the region
through the morning. Breezy southerly winds will slowly turn more
westerly by later today. Another round of snow showers will then
move into the area this afternoon/evening as the air mass turns
cooler for the night. A brief return to weak, warmer high pressure
is expected on Tuesday. However, the next wet, breezy system is
now on track to begin Tuesday afternoon/evening and persist for
multiple days. The main emphasis for heaviest snowfall will be the
mountains of northwest Montana, north-central Idaho, and the
ID/MT border.
