Area Forecast Discussion
National Weather Service Spokane WA
248 AM PST Sat Jan 5 2019

.SYNOPSIS...
We will have one more day of dry weather today, then the weather
will become quite a bit more active beginning tonight and
lingering well into next week. Rain and mountain snow with windy
conditions are likely for tonight into Sunday. Another round of
mainly mountain snow is possible Sunday night into Monday. More
wet weather is expected again Tuesday night into Wednesday.

&&

.DISCUSSION...
Today through Sunday...Satellite imagery shows a low pressure
system in the Gulf of Alaska and a closed low off the NorCal
coast. Model guidance is similar showing these two features
merging, then moving northeast through the Pacific Northwest
tonight and Sunday. This will bring the next round of
precipitation to the area. or today there may be some light snow
showers near the Cascade crest, otherwise conditions will be dry.
Fog and low clouds have developed in the Cascade valleys and along
the Columbia river near Wenatchee and that looks like it will
linger until mid morning before clearing out. Temperatures will be
on the warm side of normal with highs mainly in the lower 40s. As
the low begins to move inland tonight the mid level flow is almost
due easterly before shifting to southerly overnight and into
Sunday. This puts the focus of the precipitation in the Cascades
and the northern mountains, then dropping up off quickly to near
zero towards the Columbia Basin through Sunday. Precipitation will
be as snow in the mountains with 3-8 inches possible by Sunday
afternoon. The Methow valley will likely pick around 1-3 inches.
The remainder of the mountain valleys will only around an inch at
best. For the lower elevation precipitation will be as rain or a
rain/snow mix. The Waterville Plateau, The northern Basin near the
Columbia river could possibly see an inch. From Davenport to the
Spokane-Coeur d'Alene metro there may be a heavy dusting to
locally a half inch. Southerly winds will be on the increase
tonight into Sunday as a low level jet develops over the Basin and
the Palouse. 850 mb winds increase to around 50-55kts between
12-15z. This is not the best time for these mid level winds to mix
to the surface, but there is a weak cold front passage and model
soundings do show 40kts or so of momentum transfer to the surface
from about Lind/Ritzville up towards the Spokane area. With this
in mind we will likely need a wind advisory out for this area.

Sunday night: A cold upper-level trof will be passing through the
Northwestern US. In addition to a general steepening of lapse
rates, we will see snow levels falling back toward most valley
floors. Models continue to indicate a secondary shortwave pivoting
within the cusp of the trof bringing a renewed threat for snow
but on a smaller scale. The GFS/NAM are among the snowier
solutions due to the development of a surface low under this
feature. The ECMWF/Canadian suggest more of an open wave and less
reflection at the surface. This has led to inconsistencies with
QPF amounts and snow as well as locations. Looking back at the
last 3-4 runs of each model suite, the general consensus would
favor the an axis from Lookout Pass to St Maries to Pullman but
confidence remains below average. Given the potentially convective
nature of this activity...it will be possible to see 1-3 inches
where this precipitation bands sets up and some areas of the
Central Panhandle Mountains where southwest winds will fuel
orographic showers...stand a chance for 3-6 inches. This could
have significant impact on Lookout Pass early Monday morning as
well as lesser traveled highways around Deary, Clarkia, and Avery.

Monday:  High pressure will strengthen over the coast and translate
inland. Snow showers will continue into the Idaho Panhandle
through Monday morning then begin to wane by the afternoon as the
atmosphere warms aloft and stabilizes. Majority of Central and
Eastern WA will be dry. This looks to be the coolest day of the
week with temperatures starting off in the teens and twenties and
warming into the 30s.

Tuesday through Thursday: There is strong agreement amongst the medium
range models of a wet storm system impacting the Inland NW. This
will feature a much more amplified trough bringing a stronger
surge of southerly winds and Pacific moisture. It is a good bet
that snow levels will be rising above valley floors but exact
timing and heights are still in question. Pattern recognition
would suggest the potential for moderate to heavy snow amounts in
the Cascades and northern mountains with a transition from snow to
rain in the lower elevations along and north of the Highway 2
corridor. This will be another breezy storm system and quite mild
likely pushing most populated communities into the 40s. Snow
levels do come down with the cold front passage on Wednesday,
however the post frontal air mass will be much more maritime in
nature so don't expect much cooling in the lower elevations and
additional precipitation falling Wednesday afternoon and Thursday
will largely be in the form of valley rain and mid to high
elevation snow.

Thursday night through Saturday: High pressure returns Thursday night
and lingers into the weekend delivering the next drying trend. A
mix of low clouds and fog Friday will give way to areas of
sunshine and potential for continued mild temperatures. /sb

.AVIATION...
06Z TAFs: Mostly VFR weather for the next 24 hours. Just mid and
high clouds for most locations, which will inhibit the formation
of fog. The exception to this is KEAT. Webcams show fog along the
river and this could build into the airport up on the plateau, but
all of the cloud cover is working against it. The next Pacific
weather system will move onshore today with precipitation crossing
the Cascades and reaching KEAT and KMWH by early evening. Rain
could make it to the WA/ID border by 06Z.  RJ
