Synopsis...
the north Idaho mountains will continue to receive snow this
evening, along with the Cascade crest near Stevens Pass. The
breezy winds will taper off overnight, and Monday will be a
relatively quiet and chilly day. More rain and heavy mountain snow
is expected Monday night into Tuesday. A breezy and wet but warm
Thanksgiving day will give way to a colder weather pattern for the
Holiday weekend with the mountains receiving several rounds of
snow. Snow levels will fall to valley floors by the weekend.

Discussion...
evening update sent out to decrease cloud cover across much of the
region away from the Cascade crest and into the basin. Drier air
is beginning to funnel into the region behind the cold front
passage from this afternoon. Dew point temperatures will lower
steadily through tonight down into the 20s from west to east.
Skies will also continue to clear out across much of eastern Washington.
This will promote strong radiational cooling as winds continue to
weaken overnight. Snow showers in the Idaho Panhandle will also
dwindle overnight. This will begin to shift our focus toward the
potential for icing on roadways, especially where moisture is
present. This may lead to a slick morning commute for Monday. The
highest threat areas will be across extreme eastern Washington and into
the Idaho Panhandle. /Svh

Aviation...
00z tafs: radar and satellite trends show the band of
precipitation associated with a surface front moving southeast at
a good clip. This will affect the kpuw/klws taf sites for the next
couple of hours before exiting to the south. Also of note is a
strong convergence band of precip just to the south of keat. A
weaker band may bring brief MVFR conditions to keat through 02z.
Dry/downslope advection from the west/northwest this evening
should disperse stratus in the evening, but fog and low stratus
will crop up toward Monday morning from kpuw to kgeg and ksff. The
next weather system will approach the keat area after 00z Tuesday.
