Snow will be another story but this disturbance will be more of a rain event as it is a warmer system. The Bitterroots of Montana and northern Idaho are going to get crushed with snow. The highest of elevations in that area will receive as much as one to two feet of snowfall. Some snow is likely for the Cascades in Washington and southern Cascades in Oregon too. Most of the peaks will pick up up to a foot of snow–The highest peaks may get up to two feet.

More rain and snow is ahead for the rest of the week, especially on Tuesday and Wednesday. Then there are some signs that it will quiet down, at least relatively, by the end of the week for Thanksgiving.
