A modified Arctic front will push south out of
Canada into the PNW in the late Sunday night thru
Monday night. Arrival is not precise. Breezy rainfall
on Sunday will transition to lowering snowfall levels
by Monday. Post-holiday travel home over the
mountains will be difficult. If the system arrives
earlier, even the coast range could see snowfall on
Sunday. SNOW showers will be probable at all elevations
by Monday night/Tuesday.
Temps will plummet into the teens west side in wind
sheltered areas. Current weather hints of a slow warming
by Fri/Sat, Dec 6,7. Another cold clipper may touch us
by Sunday/Monday Dec 8,9 for rain at the surface, snow
at low elevations. This event will be the coldest in quite
some time, so be prepared (livestock water, plumbing, etc).
