.SYNOPSIS...
A strong and moist Pacific storm will bring valley rain and
mountain snow to the Cascades this afternoon and spread across
much of the Inland Northwest overnight. Then windy to breezy
conditions with mountain snow showers are expected on Saturday and
Sunday. An active and somewhat wet weather regime will continue
into the next week.

.DISCUSSION...
Due to increased precipitation and winds with the incoming weather
system, deemed it appropriate to let the Air Stagnation Advisory
to expire this morning. Also received reports of freezing rain
near Leavenworth with light snow in Omak. The precipitation band
it pushing east of the crest. /rfox

.AVIATION...
18Z TAFS: Cigs and vsbys will improve this morning as the low
levels mix ahead of the advancing warm front from KEAT to KGEG.
VFR conditions will prevail from KPUW to KLWS under light east to
southeast winds. A very moist Pacific storm system will spread
-SN/-RA from the Cascades eastward through the afternoon. Did slow
down the timing slightly with the main precipitation reaching KEAT
after 21z, KMWH 22z and KGEG after 00z. Pcpn will vary btwn -SN,
-RA and -FZRA at KEAT and possibly KMWH and could be moderate at
times. Warmer conditions will bring rain to KGEG/KSFF/KCOE/KPUW/KLWS.
Ceilings with the precipitation are once again expected to drop to
MVFR or even IFR conditions. By Saturday morning, post frontal
westerly winds will increase, although some areas of MVFR
cigs/vsbys will linger. /rfox
