Area Forecast Discussion
National Weather Service Spokane WA
227 PM PST Thu Nov 22 2018

.SYNOPSIS...
Rain and mountain snow will arrive across the Pacific Northwest in
time to impact travel for the Thanksgiving holiday. Mountain
passes will likely experience accumulating snow tonight and
Friday. The potential for heavy mountain accumulations Friday
night into Saturday has prompted Winter Storm Watches for many
passes across the Pacific Northwest.

&&

.DISCUSSION...
Tonight and early Friday...The next in a series of weather
disturbances will move across the forecast area tonight. Moisture
along the warm front will increase to above normal, but not much
more. There is some consistency that a surface low will spin up
east of the Cascades and this will increase up-sloping flow into
the east slopes of the Cascades at about the same time as the best
forcing moves across the area. Between 06-12z the low moves up
around Colville and will shift the focus of the best precipitation
up to that area. It looks like moderate snow for the east slope
valleys with areas like Plain, Lake Wenatchee, The Methow valley,
Loup Loup Pass and Blewett Pass getting 2-5 inches of snow. The
mountains will see much more with 6-12 inches above 4500 feet
possible. The Okanogan Highlands and northeast valleys don't look
like they will get as much, but still 1-3 inches are possible.
Sherman Pass may see 4-6 inches of snow by Friday afternoon. With
that in mind a Winter Weather Advisory for snow was issued for the
East Slopes of the Cascades for tonight through Friday. Another
forecast challenge for tonight will be the precipitation type in
the deep basin. Fog and stratus developed behind the precipitation
from overnight and satellite imagery is showing an area of
fog/stratus from just east of Moses lake east to the Waterville
Plateau. Temperatures in this are at or just below freezing now
and any more warming will be quite limited now that the upper
clouds are moving into the region. As such, some light freezing
rain was added to the deep basin zone. Accumulations are not
expected to be very much and this will be monitored in case there
is a need for a short fused advisory. One other thing of note,
winds will be on the increase for the Basin, Palouse and up
towards the West Plains. The timing for very gusty winds is not
the best, but there will be gusts 25-30 mph and locally to 35 mph.
Tobin

Friday:
A rather robust shortwave trough currently over the Gulf of Alaska
will move through the region. Precipitation should start to spread
inland around midday, with the most intense bands of precipitation
expected late Friday afternoon through Friday night. These intense
rain / snow bands might be a bit spotty in nature, and hi-res
guidance suggests they will set up generally in far eastern WA,
but especially the Idaho Panhandle. Snow levels should start
between 3000-4000 ft with snow impacting Lookout Pass, and will
lower to potentially around 2000 ft as precipitation diminishes
Friday night. As such, upwards of a foot of snow is expected at
pass level, with potentially a dusting down into the city of
Spokane. Winter Storm Warnings and Advisories have been posted to
reflect these likely impacts to holiday travel.

Southwest winds are also likely to increase over the Palouse as
the front passes through. Cold and wet conditions are also
expected as the winds pick up Friday evening.

Saturday and Sunday:
Conditions will begin to dry out during the day Saturday as drier
northerly flow aloft moves over the region. The upper level ridge
axis then moves overhead the region late Saturday through Sunday,
bringing fair weather for most of the weekend. Much of the area
could clear out on Saturday, with increasing clouds Saturday night
into Sunday. Look for high temperatures in the mid 30s to around
40 degrees in the Valleys, which is within a few degrees of normal
for this time of year.

Monday through Thursday:
Unsettled weather returns to the region as a series of storm
systems takes aim at the Pacific Northwest. The first appears to
arrive on Monday, and has the making of an atmospheric river
system with moisture tap originating in the subtropics. Integrated
Vapor Transport (IVT) values are projected to reach near 1000
kg/m/s off the coast on Monday, with PW values up to 0.9"
extending inland east of the Cascades. This warm tap of moisture
will eventually scour out the cold air (though it may take a bit
of time to do so), and snow levels may eventually arise above most
major Cascade and Idaho pass levels. Current projections have snow
levels lowering again toward the middle of or late next week,
with periods of unsettled weather continuing through the week.

.AVIATION...
18Z TAFs: Precipitation with the passing cold front will exit the
Idaho Panhandle around sunset this afternoon. Isolated to
scattered rain and snow showers will be possible with mountain
obscurations expected. Otherwise expect KGEG/KSFF/KCOE/KPUW/KLWS
to have VFR conditons with KCOE dropping to MVFR briefly as the
showers exit the region. Fog and stratus has developed across the
Columbia Basin behind the front and with light easterly winds the
boundary layer moisture is piling up against the Cascades.
Guidance suggest some afternoon clearing, but confidence is not
very high and expect IFR/LIFR conditions through 00z. The next
weather system is not far behind. Precipitation should begin
along the crest of the Cascades by 00z and push east through the
night. This is a bit wetter and stronger system and will spread
rain across the region tonight with light to moderate snow
possible for airfields in the Methow Valley over the Okanogan
Highlands and possibly the Wenatchee valley. MVFR/IFR conditions
will be possible for all TAF sites overnight. KMWH/KEAT will
likely see IFR/LIFR conditions return. Tobin
