.KEY MESSAGES...

- Colder temperatures over weekend into early next week with
  occasional chances for snow.

&&

.SYNOPSIS...
Temperatures cool to below normal over the weekend. A couple of
weather systems Saturday and Monday night week will bring the
potential for additional light snow.

&&

.DISCUSSION...
Friday through Sunday: Much drier modified continental polar air
has filtered in bringing clearing skies and dry conditions.
There will be breezy north winds in the Okanogan valley and
upper Columbia Basin gusting up to 35 mph before sunset thanks
to a +6 mb gradient from Kelowna BC to Ephrata. A shortwave
trough will move through the upper ridge and bring snow showers
to Stevens Pass and far SE WA/southern Panhandle Saturday. The
Palouse and Camas Prairie could see some snowflakes Saturday
evening with this system but no impacts expected. Sunday morning
will be cold in the teens to upper 20s as synoptic descent will
clear out clouds (especially closer to the Canadian border) and
the still present dry airmass promotes strong radiational
cooling.

Monday through Friday: Precipition chances increase Monday as
decaying atmospheric river moisture plume sags south from the
central BC coast Sunday night into Monday. The best timeframe
for lowland snow out of this system is Monday night in the
eastern third of Washington and north Idaho as a shortwave
trough rides around the top of the strong ridge in the Gulf of
Alaska and pivots towards the Pacific northwest. There is a
10-20% chance of an inch or more of snow for extreme eastern
Washington and a 20-50% chance for north Idaho from from Monday
afternoon to Tuesday afternoon. We dry back out for Wednesday
and temperatures moderate back to around normal. Unsettled
conditions continue late next week but not expecting any
significant storms with a strong ridge offshore blocking
systems.

.AVIATION...
00Z TAFs: A few areas of low stratus have been slow to clear,
even well into this afternoon. Overnight, expect 10-30% chance
of fog forming east of Moses Lake around 08z and advecting west
towards KEAT. Confidence too low for prevailing fog in the KMWH
or KEAT TAF. Incoming upper-level cloud cover overnight may, at
least partially, inhibit fog from being very widespread by
Saturday morning.

.FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Low confidence
in any fog development/timing into Saturday.


-----------------------

Confidence descriptors:
