AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
231 PM PST Sun Feb 16 2014

.SYNOPSIS...
The active weather pattern will continue through Thursday. The
East Slopes of the Cascades, as well as northeast Washington and
north Idaho will have a good chance of accumulating snow with each
storm that moves through the region. The Columbia Basin and
Palouse will experience windy conditions tonight through Monday.
On Wednesday and Thursday, snow levels will drop to the valley
floors over most of the Inland Northwest. Drier, more stable
weather is expected next weekend.

&&

.DISCUSSION...
Tonight through Monday...The large upper low in the Gulf of Alaska
will send another strong low pressure system into the Inland
Northwest tonight.

*Precipitation/Snow levels: There will be strong mid level
 southwest flow with this system through Monday morning with
 models hitting the Cascades, Northeast Washington Mountains, and
 North Idaho Panhandle hardest through tonight where upslope flow
 and isentropic lift will be maximized. The band of precipitation
 will then gradually shift south into Monday morning where
 precipitation will be on the increase over the south Idaho
 Panhandle and southeast Washington. This will result in difficult
 travel over Lookout Pass.

 The GFS, NAM, and SREF solutions are showing around 2 inches of
 liquid near the Cascade crest with significant slop over moisture
 east of the crest with an inch of liquid in Plain and even up to
 a quarter inch in Wenatchee. Snow levels are expected to be down
 to the valley floors as the intensity of the precipitation should
 keep all areas including Leavenworth and Stehekin as
 snow...although a mix is possible initially as precip develops
 with wet bulb temperatures this afternoon in the mid 30s. Given
 the strong southwesterly flow and dynamic lift with this system
 will go with this idea with valley accumulations of 5-11 inches
 and mountains 8-18 inches with even higher amounts near 2 feet
 near the immediate Cascade crest. Will upgrade the East Slopes to
 a Winter Storm Warning. Will also upgrade the Northeast
 Washington Mountains and North Idaho Panhandle to a warning.
 Snow levels will be tricky in these areas with models showing
 warm air advection from southerly surface winds bringing a slight
 rise in snow levels to 2000-2500 feet. Areas near the Canadian
 border and elevations above 2000 feet will see the most
 significant accumulations with heavy mountain snow accumulations
 a guarantee. The strong mid level flow with this system will give
 the Moses Lake area little to no precipitation. Snow levels from
 Spokane southward are expected to be 2500-3500 feet resulting in
 mainly rain for the valleys and snow in the mountains.

*Wind: 850mb winds increase to 50-60 knots tonight over southeast
 Washington extending up into the Spokane area. The tricky part is
 how much mixing of the atmosphere will there be for these winds
 to mix down. Soundings in the warm sector show limited mixing
 potential so for now will not issue any advisories. However high
 resolution UW WRF-GFS does indicate localized gusts to 45-50 mph
 not out of the question especially around Pomeroy and Alpowa
 Summit. JW

Monday night through Tuesday night...There will be a brief lull or
decrease in the overall precipitation on Monday night, but
another storm system will be moving over the region on Tuesday
into Tuesday night. This system is not quite as moist as the
previous (several) weather st stems, although it will still be a
pretty moist system. But it also is a quick-moving system, which
will limit the overall precipitation totals. The mountains should
be the beneficiaries of this system, especially near and just east
of the Cascade crest, as well into the Idaho panhandle. If the
forecast holds, another round of winter weather highlights may
become necessary.

As far as the valleys go, warm air will surge northward Tuesday
afternoon in southwest flow, keeping most of the precipitation in
the non-freezing liquid form up to the I-90/Highway 2 corridor.
Further north, enough cold air will be in place for precipitation
to begin as snow. However, during the afternoon the snow may mix
with or change to rain, which would limit any snowfall
accumulations. Snow levels should come crashing back down Tuesday
night as cold air filters south and east, with some accumulations
likely once again. How fast this occurs further south will
obviously dictate how much snow can accumulate in the valleys
toward I-90. ty

Wednesday through Sunday...Upper level high pressure slowly begins
to build in the Pacific...while mean troughiness is east of the
divide to begin this portion of the forecast. A couple of weak
short wave disturbances will move through the region in the
resultant northwest flow to keep conditions unsettled Wednesday
and Thursday. Then high pressure begins to amplify out near 140w
on Friday before moving towards the Pac NW through the weekend.
This should finally bring a break in the active weather pattern.

Wednesday through Thursday night...The upper level disturbance
from Tuesday will slowly move out on Wednesday...with weak ridging
building into the region during the afternoon. We also lose the
nice moisture tap. But there will be enough up- sloping flow into
the Cascades and eastern mountains to support rain and snow showers
through the day...with the higher elevations possibly picking up
an inch or two of snow. Little if any precipitation is expected
out side of the mountainous areas.

Another fast moving wave will move through the Inland Northwest
Wednesday night and Thursday. While pacific moisture increases
with this front the tap moisture is relatively light compared to
the past several storms. But model QPF is fairly impressive with
the Cascades and the eastern mountains expected to see another
good shot of precipitation. Vertical profiles show precipitation
as all snow for most for areas outside the southern
Basin...southern Palouse and the L-C valley. Snow accumulations
for the higher terrain should be pretty good again. Southwest
winds will be on the increase with sustained winds 15 to 20 mph
with gust 25 to 30 mph.

Thursday night through Sunday...Snow shower will linger through
most of the day across the Cascades and Panhandle mountains on
Friday as the aforementioned disturbance moves out of the area. The
the area of high pressure in the eastern Pacific will strengthen
and slowly move inland through the weekend. This will keep the
forecast area in a northwest to northerly flow. This pattern is
typically cool and mostly dry. Up-sloping flow into the Panhandle
mountains will almost always result in some kind of shower
activity and that will not be any different this time...but timing
and amounts will be very variable. Otherwise we expect a mostly
dry forecast with temperatures on the cool side of normal. /Tobin

&&

.AVIATION...
18Z TAFS: Rain and snow showers will mainly be confined to the
upslope mountainous zones though this afternoon.  MVFR stratocumulus
at KGEG/KSFF/KCOE will be gradually lifting through the afternoon
becoming VFR by 22z.  The next weather system will spread a mix of
rain and snow into the region tonight...with the main focus north of
Interstate 90 as strong southerly winds upslopes into the high
terrain.  Gusty winds will impact all TAF sites except KEAT which
stay sheltered as the surface but LLWS will develop around 05z. The
band of precipitation  will gradually sag south overnight into
Monday morning.  Lowering CIGS are expected after precipitation
develops with MVFR conditions expected over the eastern TAF sites
and possibly KEAT.  Model show quite a bit of differences regarding
the precise onset of precipitation around the KGEG-KSFF-KCOE
corridor with precipitation type also more uncertain so confidence
is lowest for these areas.
