Area Forecast Discussion

332 PM PST SUN FEB 7 2016

.SYNOPSIS...
Strong high pressure will develop tonight and persist into
Wednesday. Dry and mild conditions are expected for the first half
of the week. A more progressive and unsettled pattern will return
late this week bringing a chance of light rain Thursday in the
Cascades and over the rest of the region Friday through the weekend.

&&

.DISCUSSION...
Tonight and Monday: A ridge of high pressure will strengthen in
over the region the next 24 hours. Mid level moisture riding up
over the ridge this afternoon will decrease through the evening. A
few flurries may be possible over the Northern Panhandle before
skies clear out overnight. Strong inversions will develop with
patchy fog possible for many of the mountain valley locations.
This inversion will be even more difficult to break on Monday
compared to today. The fog that does develop may burn off a bit
later in the day and keep surface temperatures in the upper 30s
to low 40s for the mountain valleys. /SVH

Monday night through Thursday...This period will be characterized
by a strong upper level ridge...light winds...cool morning low
temperatures with varying fields of fog and low clouds each
morning and a general break out over most of the region during the
afternoon with high temperatures rising above normal for most
locations. The Palouse and L-C valley will be the clearest and
mildest regions with a general easterly gradient keeping fog
scarce and promoting well above average temperatures due to
downslope compressional warming each day. The deep basin and
Cascades valleys where the easterly gradient will transport and deposit
the more stagnant air will see the most fog and low clouds and the
weakest daily clearing potential below 4000 feet. Thursday the
ridge axis will begin to shift eastward...and allow a more moist
Pacific southwesterly flow to take over. Precipitation chances
will begin to increase over the Cascades and northern
mountains...but with little impact over the lion`s share of the
forecast area beyond increasing high clouds.

Thursday night through Sunday...Models are in pretty good
agreement for the remainder of the extended forecast period.
Thursday night the upper level rideg axis continues to migrate
east and out of the region with increasingly moist southwesterly
flow becoming established. Precipitation chances will begin to
spread through the forecast area from west to east. Snow levels
will remain quite high in this southwest warm advection
scenario...but the colder boundary layer air trapped in the
cascade Valleys may allow some freezing rain as early as Thursday
morning and a better chance on Friday morning. Friday will be a
transition day between the dry ridgy weather regime and a more
active Pacific storm regime. A cold front with a significant
potential fro valley rain and mountain snow will cross the region
on or about Friday night and Saturday. This evolution will scrub
the region by wiping out any lingering inversion and allow a
lowering of snow levels for subsequent storms. Another and
possibly better organized storm may approach the region on
Sunday...but model details are sketchy and unreliable at this
time. /Fugazzi


&&

.AVIATION...
00Z TAFS: A strong upper level ridge aloft and building high
pressure over Idaho will promote clearing skies tonight after mid
level cloud decks move out to the east this evening. A strong
nocturnal inversion is expected to develop overnight with fog
development by dawn especially near water courses. The best
candidates for morning LIFR conditions will be at KGEG and KSFF
and less likely but possible at KLWS and KEAT. Enough mixing is
expected to occur by 18Z or so to evaporate fog for VFR
conditions through 00Z Tuesday. /MJF

scenario...but the colder boundary layer air trapped in the
cascade Valleys may allow some freezing rain as early as Thursday
morning and a better chance on Friday morning. Friday will be a
transition day between the dry ridgy weather regime and a more
active Pacific storm regime. A cold front with a significant
potential fro valley rain and mountain snow will cross the region
on or about Friday night and Saturday. This evolution will scrub
the region by wiping out any lingering inversion and allow a
lowering of snow levels for subsequent storms. Another and
possibly better organized storm may approach the region on
Sunday...but model details are sketchy and unreliable at this
time. /Fugazzi

.AVIATION...
18Z TAFS: Shallow fog around the Spokane Area will result in VLIFR
conditions through 19Z, but should then quickly burn off for the
afternoon. High pressure will continue to build in today. High and
mid level clouds will filter in over the ridge with cigs generally
remaining above 8 kft agl. These clouds will thin out tonight with
more shallow fog possible around the region, especially near water
bodies and in deep valleys (including KSFF). /SVH

.SYNOPSIS...
A weak upper level disturbance will produce clouds over the Inland
Northwest today. Strong high pressure will develop tonight and
persist into Wednesday. Dry and mild conditions are expected for
the first half of the week. The chance for light rain will return
Thursday, Friday, and Saturday.

.DISCUSSION...
Made some adjustments to the cloud cover for today. Much of the
region is only seeing very thin cirrus as mid level moisture tops
the ridge of high pressure. These clouds will thicken a bit during
the day and satellite is already showing some of this thicker cloud
cover push east of the Cascades this morning. Much of the southern
portion of the region will see filtered sunshine from around Moses
Lake to Kellogg and points southward. Clouds will likely increase
and thicken points northward. Very light precip will also be
possible, but will mainly be in the form of some sprinkles/flurries
for the mountains. /SVH

A weak upper level disturbance will produce clouds over the Inland
Northwest today. Strong high pressure will develop tonight and
persist into Wednesday. Dry and mild conditions are expected for
the first half of the week. The chance for light rain will return
Thursday, Friday, and Saturday.

&&

.DISCUSSION...

Today and Tonight: A weak upper level disturbance will over-top a
high pressure ridge today. Bands of clouds will accompany this
weak feature. As of 230 AM, the NWS radar mosaic was detecting
rain showers off the coast of the Olympic Peninsula, and by mid
to late morning some of this light precipitation should reach the
northern Cascades. On whole, precipitation should be weakening it
over-tops the 500mb ridge. There shouldn`t be much left of the
showers after crossing the Cascades. Some flurries and sprinkles
have been added to the forecast for the counties along the
Canadian border. Elsewhere, light winds and increasing clouds will
hinder warming this afternoon. High temperatures have been lowered
a bit. Skies should clear this evening from west to east as the
upper level disturbance slides into Montana. Strong mid-level
warming under our building ridge will produce a strong temperature
inversion, especially over central Washington. Mountains will
remain relatively mild with cold air settling into the valleys.
There is a good chance that we will see more fog tonight in the
valleys of northeast and north central Washington with the
strengthening inversion and surface dewpoints slowly recovering
following Friday night`s strong front.

Monday and Tuesday: The temperature forecast Monday and Tuesday
will be tough. Warming aloft will produce a very strong
temperature inversion. Mountain ridges and mid-slopes will have
the potential to be in the 40s and low 50s Monday and Tuesday
while lowlands could remain in the 30s and low 40s. A light
easterly pressure gradient will produce enough mixing to keep the
southern Idaho Panhandle and the Palouse free of fog and low
clouds. Similar weather patterns this time of year produce high
temperatures in the 50s for places like St Maries, Pullman,
Lewiston, Pomeroy, and LaCrosse. Afternoon temperatures in the
upper 40s to near 50 aren`t out of the question for Spokane, Coeur
d`Alene, Davenport, and Moses Lake. The presence of fog (and how
long it lingers Monday and Tuesday) will determine how warm
temperatures get. /GKoch

Wednesday through Saturday: Models are in good agreement of an
upper ridge moving east of the area for mid week as an upper
trough slowly advances towards the area from the west. Overall
models have trended slower with the trough with generally dry
weather expected Wednesday through Friday. Although a weak wave
tracking across could produce a few showers Wednesday night into
Thursday. With the upper ridge axis to the east and an upper
trough to the west of the region...this will place the Inland NW
in a mild southwest flow through Friday with above normal
temperatures. Late Friday into Saturday the latest 00z runs of the
GFS and ECMWF track the upper trough inland with a cold front
passage. This will likely bring a round of light to locally
moderate precipitation but with some timing uncertainty POP`s were
limited to chance. Snow levels come down behind the cold front and
could see snow showers returning to the mountains. JW

&&

.AVIATION...
12Z TAFS: Spokane, Coeur d`Alene, and Sandpoint will experience a
bit of shallow fog this morning. At this time, it doesn`t appear
that the fog will linger much past 16z-17z since it is relatively
patchy and our air mass is quite mild for this time of the season.
Bands of mid and high clouds will spill over a high pressure ridge
today with cloud bases mainly at or above 10 thousand feet.
Clearing skies this evening will promote more radiation fog over
the valleys of far north Idaho as well as northeast and north
central Washington. /GKoch

There is a good chance that we will see more fog tonight in the
valleys of northeast and north central Washington with the
strengthening inversion and surface dewpoints slowly recovering
following Friday night`s strong front.

Monday and Tuesday: The temperature forecast Monday and Tuesday
will be tough. Warming aloft will produce a very strong
temperature inversion. Mountain ridges and mid-slopes will have
the potential to be in the 40s and low 50s Monday and Tuesday
while lowlands could remain in the 30s and low 40s. A light
easterly pressure gradient will produce enough mixing to keep the
southern Idaho Panhandle and the Palouse free of fog and low
clouds. Similar weather patterns this time of year produce high
temperatures in the 50s for places like St Maries, Pullman,
Lewiston, Pomeroy, and LaCrosse. Afternoon temperatures in the
upper 40s to near 50 aren`t out of the question for Spokane, Coeur
d`Alene, Davenport, and Moses Lake. The presence of fog (and how
long it lingers Monday and Tuesday) will determine how warm
temperatures get. /GKoch

Wednesday through Saturday: Models are in good agreement of an
upper ridge moving east of the area for mid week as an upper
trough slowly advances towards the area from the west. Overall
models have trended slower with the trough with generally dry
weather expected Wednesday through Friday. Although a weak wave
tracking across could produce a few showers Wednesday night into
Thursday. With the upper ridge axis to the east and an upper
trough to the west of the region...this will place the Inland NW
in a mild southwest flow through Friday with above normal
temperatures. Late Friday into Saturday the latest 00z runs of the
GFS and ECMWF track the upper trough inland with a cold front
passage. This will likely bring a round of light to locally
moderate precipitation but with some timing uncertainty POP`s were
limited to chance. Snow levels come down behind the cold front and
could see snow showers returning to the mountains. JW

.AVIATION...
06Z TAFS: A building ridge aloft and weak high pressure building
over the region will create dry and benign conditions for the
next 24 hours. In spite of light northeast winds,
temperature/dewpoint spreads at KGEG/KSFF/KCOE are just 3 degrees
at 06Z and could lead to fog or low stratus overnight. Otherwise,
expect VFR conditions at remaining TAF sites through 06Z Monday.

Area Forecast Discussion

308 AM PST SUN FEB 7 2016

.SYNOPSIS...
A weak upper level disturbance will produce clouds over the Inland
Northwest today. Strong high pressure will develop tonight and
persist into Wednesday. Dry and mild conditions are expected for
the first half of the week. The chance for light rain will return
Thursday, Friday, and Saturday.

&&

.DISCUSSION...

Today and Tonight: A weak upper level disturbance will over-top a
high pressure ridge today. Bands of clouds will accompany this
weak feature. As of 230 AM, the NWS radar mosaic was detecting
rain showers off the coast of the Olympic Peninsula, and by mid
to late morning some of this light precipitation should reach the
northern Cascades. On whole, precipitation should be weakening it
over-tops the 500mb ridge. There shouldn`t be much left of the
showers after crossing the Cascades. Some flurries and sprinkles
have been added to the forecast for the counties along the
Canadian border. Elsewhere, light winds and increasing clouds will
hinder warming this afternoon. High temperatures have been lowered
a bit. Skies should clear this evening from west to east as the
upper level disturbance slides into Montana. Strong mid-level
warming under our building ridge will produce a strong temperature
inversion, especially over central Washington. Mountains will
remain relatively mild with cold air settling into the valleys.
There is a good chance that we will see more fog tonight in the
valleys of northeast and north central Washington with the
strengthening inversion and surface dewpoints slowly recovering
following Friday night`s strong front.

Monday and Tuesday: The temperature forecast Monday and Tuesday
will be tough. Warming aloft will produce a very strong
temperature inversion. Mountain ridges and mid-slopes will have
the potential to be in the 40s and low 50s Monday and Tuesday
while lowlands could remain in the 30s and low 40s. A light
easterly pressure gradient will produce enough mixing to keep the

Strong high pressure will build over the Pacific Northwest Sunday
bringing dry weather and light winds. Dry and mild conditions are
expected for the first half of the week. The chance for light
rain will return Thursday, Friday, and Saturday.


&&

.DISCUSSION...
Main purpose of the evening update was to lower min temperatures
and sky cover to account for recent trends in observations. Cloud
cover has shifted to the south, leaving most of the forecast area
under clear skies. This, along with light winds, has allowed for
optimal radiational cooling with some of the northern valleys
cooling 10 degrees in the hour after sunset. Omak and Republic
have already fallen to the mid 20s as of 10 pm. At this rate,
they may reach the upper teens before high clouds rolling through
the offshore ridge move overhead. /Kelch

.SYNOPSIS...
Strong high pressure will build over the Pacific Northwest Sunday
bringing dry weather and light winds. Dry and mild conditions are
expected for the first half of the week. The chance for light
rain will return Thursday, Friday, and Saturday.

&&

.DISCUSSION...

Tonight and Sunday...Ridge of high pressure building over the area
with the ridge placement just west of the Washington Cascades is
positioned in such a way as to allow minor disturbances and
moisture to flux through it and overtop it and move through
Eastern Washington and Northern Idaho during this time interval.
Since the disturbances are very weak and the moisture fairly
limited except at the middle and upper levels the probabilities of
precipitation remain quite low and confined primarily to the
northern periphery of the mountain zones but sky cover forecast
will reflect the presence of the moisture and disturbances fluxing
through with varable periods of cloud cover ranging from Partly
cloudy to cloudy. With the low amplitude of the ridge in the
vicinity and the lower level winds tending to have an easterly
component the forecast temperatures will be slightly on the warm
side of what would be considered normal for this time of year.
/Pelatti

Sunday night through Saturday...Model agreement suggests high
confidence of dry and stable conditions over the region through
Wednesday as an upper level ridge builds and becomes established.
This rideg will probably not stick around long enough to allow
significant air quality deterioration...but areas of fog and low
clouds will become increasingly common especially in the morning
hours through the middle of the week. The Palouse and points south
will benefit from a dry downslope breeze and should experience
considerable sunshine. Temperatures will run slightly above
average for this time of year and may be downright mild during the
days depending on sunshine prevalence.

On or about Thursday the latest GFS and ECMWF models are in
surprisingly good agreement for that far out in depicting a
breakdown of this ridge featuring a pair of cold
fronts...probably bearing mountain snow and valley rain
showers...the first one passing through Wednesday night and the
second on Friday night. This will herald a return to a more active
and progressive pattern. /Fugazzi

&&

.AVIATION...
00Z TAFS: A building ridge aloft and weak high pressure building
over Idaho will create dry and benign conditions over the region
for the next 24 hours. Moisture cresting this ridge will promote
occasionally thick mid level cloud ceilings AOA 10kft MSL. This
cloud cover will likely limit temperature drops tonight
stabilizing above the dew point and thus morning fog and low
stratus is unlikely at any TAF sites Sunday morning. VFR
conditions are expected at all TAF sites through 00Z Monday. /MJF

considerable sunshine. Temperatures will run slightly above
average for this time of year and may be downright mild during the
days depending on sunshine prevalence.

On or about Thursday the latest GFS and ECMWF models are in
surprisingly good agreement for that far out in depicting a
breakdown of this ridge featuring a pair of cold
fronts...probably bearing mountain snow and valley rain
showers...the first one passing through Wednesday night and the
second on Friday night. This will herald a return to a more active
and progressive pattern. /Fugazzi

.AVIATION...
18Z TAFS: A bit of slow stratus clouds still remains this morning
but primarily it is middle and high clouds streaming over the top
and through the ridge moving into the area as the trof responsible
for last nights increased winds and generally light precipitation
moves away and exits to the east. The ridge will remain for some
time so the forecast has some varying degrees of middle and high
clouds remaining as well with the low level winds becoming
generally more light and variable. /Pelatti

.SYNOPSIS...
Today will be breezy with rain and snow showers over the
mountains of the Idaho Panhandle and over the Cascades. Strong
high pressure will build over the Pacific Northwest Sunday
bringing dry weather and light winds. Mild high pressure is
expected for the first half of the week. The chance for light rain
will return Thursday, Friday, and Saturday.

.DISCUSSION...
Updates to the morning forecast include warming the forecast high
temperatures a few degrees and reworking some of the cloud cover
overhead this morning as a combination of middle and upper level
clouds streaming through and over the top of the ridge building
into the area is overrunning some lower level stratus clouds, but
not as much as was prevalent in the area a day or more ago. With
the upper level winds peaking overnight and decreasing through the
day this morning as the trof/weather disturbance associated with
them exits to the east there will be some gusts to the afternoon
winds but not to the degree which occurred overnight. /Pelatti

353 AM PST SAT FEB 6 2016

.SYNOPSIS...
Today will be breezy with rain and snow showers over the
mountains of the Idaho Panhandle and over the Cascades. Strong
high pressure will build over the Pacific Northwest Sunday
bringing dry weather and light winds. Mild high pressure is
expected for the first half of the week. The chance for light rain
will return Thursday, Friday, and Saturday.


&&

.DISCUSSION...

Today: A narrow band of precipitation (along a quick moving
frontal system) will impact the Idaho Panhandle early this
morning. As of 2 AM, moderate snow was falling over the mountains
of Shoshone county above 3500 feet. DOT cameras at Lookout Pass
showed accumulations on Interstate 90 at 4700 feet. The most
significant snow at Lookout Pass will occur between now and
sunrise with 2 to 4 inches expected before snow decreases to snow
showers by mid morning. Post frontal snow showers will also occur
over the northern Cascades early this morning. Westerlies of 45 to
55kts at 700mb will push some of these convective bands as far
east as Plain, Mazama, Twisp, and upper portions of Lake Chelan.
However, accumulations this morning should be an inch or less
given the mild temps and transient nature of these showers. Even
web cameras at Stevens Pass suggest the snow is having a tough
time accumulating so the Winter Weather Advisory for the East
Slopes of the Northern Cascades will be cancelled.

Breezy southwest winds will make it feel chilly today despite
above average temperatures. A few wind sensors gusted into the
40-45mph range with the passage of the cold front early this
morning, but the gustiness has abated a bit over the Palouse, West
Plains, and Upper Columbia Basin. Our surface pressure gradients
will relax through the day today, but we may see a resurgence of
gusts to 35 mph around mid morning following sunrise. By early
evening, winds region-wide should be 5 mph or less as surface high
pressure quickly becomes established under a building upper ridge.

Tonight and Sunday: Our upper ridge will have a good deal of mid
and upper level moisture associated with it tonight into Sunday.
Looking at model soundings from the GFS and NAM, it is tough to
tell how thick clouds will be tonight into Sunday. The sounding
carry a good deal of moisture, but don`t saturate suggesting
transient bands of clouds. A bit of very light precipitation is
depicted by the NAM and GFS Sunday afternoon and evening over the
Cascades, Okanogan Highlands, and northeast Washington mountains.
A 20-30 percent chance of light rain and snow has been added to
the forecast with little mountain snow accumulation expected.
/GKoch

Sunday night through Friday: Models continue to show an upper
ridge building Monday and Tuesday. This will lead to strengthening
temperature inversions with areas of low clouds and patchy fog
forming in the valleys. Above the inversion mostly clear skies and
mild conditions will occur in the mountains as 850mb temperatures
rise into the 5-10C range. The palouse, Lewiston area, possibly
extending west towards Ritzville will benefit from easterly
downslope boundary layer winds which keeps these areas out of the
low clouds with very mild temps in the lower to mid 50s. A few
record highs are possible. The ridge begins to weaken on Wednesday
however mild temperatures will continue. Thursday and Friday an
upper trough begins to approach the Washington and Oregon coast.
Models disagree with the details of when the next round of
potential precipitation arrives so did not make many changes.
Prevailing southwest flow however should result in a continuation
of mild temperatures and high snow levels when precip does arrive.

.AVIATION...
12Z TAFS: Strong mixing behind a departing cold front will
disperse the low clouds that have plagued the region for days. VFR
conditions are expected at the TAF sites today and most of
tonight. There may be a bit of fog development in the sheltered
areas of northeast Washington and north Idaho overnight into
Sunday morning, but that is at the outer portions of this 24 hour
TAF. /GKoch

Area Forecast Discussion
National Weather Service Spokane WA
300 AM PST SAT FEB 6 2016

.SYNOPSIS...
Today will be breezy with rain and snow showers over the
mountains of the Idaho Panhandle and over the Cascades. Strong
high pressure will build over the Pacific Northwest Sunday
bringing dry weather and light winds. Mild high pressure is
expected for the first half of the week. The chance for light rain
will return Thursday, Friday, and Saturday.


&&

.DISCUSSION...

Today: A narrow band of precipitation (along a quick moving
frontal system) will impact the Idaho Panhandle early this
morning. As of 2 AM, moderate snow was falling over the mountains
of Shoshone county above 3500 feet. DOT cameras at Lookout Pass
showed accumulations on Interstate 90 at 4700 feet. The most
significant snow at Lookout Pass will occur between now and
sunrise with 2 to 4 inches expected before snow decreases to snow
showers by mid morning. Post frontal snow showers will also occur
over the northern Cascades early this morning. Westerlies of 45 to
55kts at 700mb will push some of these convective bands as far
east as Plain, Mazama, Twisp, and upper portions of Lake Chelan.
However, accumulations this morning should be an inch or less
given the mild temps and transient nature of these showers. Even
web cameras at Stevens Pass suggest the snow is having a tough
time accumulating so the Winter Weather Advisory for the East
Slopes of the Northern Cascades will be cancelled.

Breezy southwest winds will make it feel chilly today despite
above average temperatures. A few wind sensors gusted into the
40-45mph range with the passage of the cold front early this
morning, but the gustiness has abated a bit over the Palouse, West
Plains, and Upper Columbia Basin. Our surface pressure gradients
will relax through the day today, but we may see a resurgence of
gusts to 35 mph around mid morning following sunrise. By early
evening, winds region-wide should be 5 mph or less as surface high
pressure quickly becomes established under a building upper ridge.

Tonight and Sunday: Our upper ridge will have a good deal of mid
and upper level moisture associated with it tonight into Sunday.
Looking at model soundings from the GFS and NAM, it is tough to
tell how thick clouds will be tonight into Sunday. The sounding
carry a good deal of moisture, but don`t saturate suggesting
transient bands of clouds. A bit of very light precipitation is
depicted by the NAM and GFS Sunday afternoon and evening over the
Cascades, Okanogan Highlands, and northeast Washington mountains.
A 20-30 percent chance of light rain and snow has been added to
the forecast with little mountain snow accumulation expected.
/GKoch

Sunday night through Friday: Models continue to show an upper
ridge building Monday and Tuesday. This will lead to strengthening
temperature inversions with areas of low clouds and patchy fog
forming in the valleys. Above the inversion mostly clear skies and
mild conditions will occur in the mountains as 850mb temperatures
rise into the 5-10C range. The palouse, Lewiston area, possibly
extending west towards Ritzville will benefit from easterly
downslope boundary layer winds which keeps these areas out of the
low clouds with very mild temps in the lower to mid 50s. A few
record highs are possible. The ridge begins to weaken on Wednesday
however mild temperatures will continue. Thursday and Friday an
upper trough begins to approach the Washington and Oregon coast.
Models disagree with the details of when the next round of
potential precipitation arrives so did not make many changes.
Prevailing southwest flow however should result in a continuation
of mild temperatures and high snow levels when precip does arrive.

.SYNOPSIS...
Another frontal system will arrive tonight bringing rain to the
lowlands and snow to the mountains. It will become windy after
midnight tonight with gusts up to 45 mph over southeast
Washington, the Palouse, and West Plains. Dry weather and light
winds will develop on Sunday and continue through mid week as a

weather is expected by the end of the work week.


&&

.DISCUSSION...
The cold front is moving across eastern Washington as of 10 pm.
This feature is much weaker than forecast since it dropped much of
its moisture as it crested the Cascades. Stronger downslope flow
has limited the amount of precipitation falling other than the
slopover near the crest. The areal coverage of the Winter Weather
Advisory has been trimmed to exclude some locations away from the
crest. Have opted to keep the advisory going since we are
expecting convergence bands to develop tonight that could bring
periods of locally heavy snow. High resolution models are favoring
the Highway 2-Stevens Pass area. There are scattered radar returns
along the crest but so far the most consolidated bands remain
south of the forecast area closer to I-90/Stampede Pass.

.DISCUSSION...
...WINDY CONDITIONS TONIGHT INTO SATURDAY MORNING...

Tonight and Saturday: A dynamic shortwave trough of lower pressure
will race across the region tonight. Satellite imagery shows the
cold front just off the coast of WA at around 2:00 PM this
afternoon. The water vapor channel indicates good darkening
immediately behind the front. This is a good signal that once the
precip shuts off, we will see low clouds mixing out and stronger
winds aloft mixing down. Precip will mainly be confined right
along the cold front for most areas. This will result in a short
duration precip event of between 2-4 hours. The exceptions will be
the east slopes of the northern Cascades and the ID Panhandle.

The slop over precip across the Cascade crest has the potential
to extend a bit further into the east slopes more than usual as
high resolution models (i.e. HRRR) indicate a moderately strong
Puget Sound Convergent Zone (PSCZ) setting up. Snow fall amounts
in the east slopes of the northern Cascades will likely be fairly
light with the front this evening, but snowfall rates may be quite
heavy underneath the PSCZ through the overnight hours. The HRRR
model shows this convergent zone first extending over the Methow
Valley late in the evening through about 2:00 AM and then
concentrating further south between Plain and Lake Chelan late
tonight into Saturday morning. It is not uncommon to see snowfall
rates of 1-2 inches per hour underneath the PSCZ due to the
convective nature of the snowfall. Because of this, we have made a
minor adjustment to the Winter Weather Advisory to include Plain
and locations along Lake Chelan such as Lucerne.

Snowfall amounts are not expected to be as heavy across the ID
Panhandle, but some ongoing snow showers are expected to continue
through Saturday morning. Some showers may be on the heavier side
behind the cold front as lapse rates steepen a bit. The main
impact will be going over Lookout Pass where around 2-4 inches of
snow will be possible.

The other impact with this storm system will be for some windy
conditions. The GFS model indicates the strongest potential for
winds. It shows winds up at 850 mbs of up around 50 kts, but other
model guidance are closer to 40-45 kts. There will be decent cold
air advection with the passage of the cold front with a degree of
confidence that these stronger winds aloft will be able to mix
down to the surface despite a nighttime passage. Strongest wind
gusts are expected to take place across the Spokane Area, on the
Palouse, and in the Northeast Blue Mtns (including around Pomeroy
and over Alpowa Summit). Strongest gust will likely occur with
cold front passage late tonight into early Saturday morning in the
range of 40-45 mph. Winds will then be generally breezy for the
rest of the day on Saturday. Gust potential will be borderline
advisory criteria, but confidence is low and duration will likely
be fairly short if achieved. /SVH

Saturday night through Friday...Model agreement is good and
consistent for multiple runs now in depicting a strong upper level
ridge over the region from Sunday through Wednesday. Confidence
is high for a run of dry weather after lingering snow showers from
Saturday`s system die out over the Idaho Panhandle. The areal
extent of at least morning fog and low clouds...potentially
deteriorating air quality and temperatures will be the main
forecast problems during this strong ridge inversion scenario.

The region may be broken out into three distinct areas of varying
weather. Firstly...over the Palouse and points south as far west
as Ritzville or so a persistent easterly gradient will likely keep
fog and low clouds to a minimum and allow temperatures to elevate
int the solid 40s and even into the 50s by mid week.

The easterly gradient will serve to pool an increasingly moist and
stagnant boundary layer in the deep basin and Cascades
Valleys...banked against the mountains. It is here where the best
chance of significant fog and stratus and the lowest chance of
daytime sun will be found. Also the coolest temperatures and
weakest diurnal swings.

Over the northern Columbia basin and many of the valleys of
northeast Washington and north Idaho a regime of overnight and
morning fog and low clouds with at least partial sunshine in the
afternoons and evenings look plausible...with the protected
valleys north of the basin slowest to scrub each day.

On or about Thursday models are coming into loose agreement on
breaking down or at least substantially weakening the upper ridge
with both the GFS and EC depicting a short wave passage either
Wednesday night or Thursday...followed by a more active close to
the work week with follow on waves. At this time none of these
disturbances looks particularly strong or organized...but well
worth increasing precipitation chances for valley rain and
mountain snow for late in the week. /Fugazzi

.AVIATION...
00Z TAFS: A strong cold front laying along the Pac coast at 00Z
will pass through KEAT around 06Z and through the eastern TAF
sites around 09Z. Ahead and along this front expect mainly rain
showers with possible MVFR ceilings...except a short period of
snow at KEAT then changing to rain. Ahead of the front especially
over the eastern TAF sites LLWS is expected after sunset decouples
the boundary layer until FROPA. Breezy and gusty conditions will
occur with the FROPA with precipitation quickly tapering
off...except for the Idaho Panhandle and possibly the KCOE TAF
site where upslope post-frontal showers will continue into the
morning hours. Generally decreasing winds and VFR conditions will
prevail during the day Saturday. /MJF

.DISCUSSION...
...WINDY CONDITIONS TONIGHT INTO SATURDAY MORNING...

Tonight and Saturday: A dynamic shortwave trough of lower pressure
will race across the region tonight. Satellite imagery shows the
cold front just off the coast of WA at around 2:00 PM this
afternoon. The water vapor channel indicates good darkening
immediately behind the front. This is a good signal that once the
precip shuts off, we will see low clouds mixing out and stronger
winds aloft mixing down. Precip will mainly be confined right
along the cold front for most areas. This will result in a short
duration precip event of between 2-4 hours. The exceptions will be
the east slopes of the northern Cascades and the ID Panhandle.

The slop over precip across the Cascade crest has the potential
to extend a bit further into the east slopes more than usual as
high resolution models (i.e. HRRR) indicate a moderately strong
Puget Sound Convergent Zone (PSCZ) setting up. Snow fall amounts
in the east slopes of the northern Cascades will likely be fairly
light with the front this evening, but snowfall rates may be quite
heavy underneath the PSCZ through the overnight hours. The HRRR
model shows this convergent zone first extending over the Methow
Valley late in the evening through about 2:00 AM and then
concentrating further south between Plain and Lake Chelan late
tonight into Saturday morning. It is not uncommon to see snowfall
rates of 1-2 inches per hour underneath the PSCZ due to the
convective nature of the snowfall. Because of this, we have made a
minor adjustment to the Winter Weather Advisory to include Plain
and locations along Lake Chelan such as Lucerne.

Snowfall amounts are not expected to be as heavy across the ID
Panhandle, but some ongoing snow showers are expected to continue
through Saturday morning. Some showers may be on the heavier side
behind the cold front as lapse rates steepen a bit. The main
impact will be going over Lookout Pass where around 2-4 inches of
snow will be possible.

The other impact with this storm system will be for some windy
conditions. The GFS model indicates the strongest potential for
winds. It shows winds up at 850 mbs of up around 50 kts, but other
model guidance are closer to 40-45 kts. There will be decent cold
air advection with the passage of the cold front with a degree of
confidence that these stronger winds aloft will be able to mix
down to the surface despite a nighttime passage. Strongest wind
gusts are expected to take place across the Spokane Area, on the
Palouse, and in the Northeast Blue Mtns (including around Pomeroy
and over Alpowa Summit). Strongest gust will likely occur with
cold front passage late tonight into early Saturday morning in the
range of 40-45 mph. Winds will then be generally breezy for the
rest of the day on Saturday. Gust potential will be borderline
advisory criteria, but confidence is low and duration will likely
be fairly short if achieved. /SVH

Saturday night through Friday...Model agreement is good and
consistent for multiple runs now in depicting a strong upper level
ridge over the region from Sunday through Wednesday. Confidence
is high for a run of dry weather after lingering snow showers from
Saturday`s system die out over the Idaho Panhandle. The areal
extent of at least morning fog and low clouds...potentially
deteriorating air quality and temperatures will be the main
forecast problems during this strong ridge inversion scenario.

The region may be broken out into three distinct areas of varying
weather. Firstly...over the Palouse and points south as far west
as Ritzville or so a persistent easterly gradient will likely keep
fog and low clouds to a minimum and allow temperatures to elevate
int the solid 40s and even into the 50s by mid week.

The easterly gradient will serve to pool an increasingly moist and
stagnant boundary layer in the deep basin and Cascades
Valleys...banked against the mountains. It is here where the best
chance of significant fog and stratus and the lowest chance of
daytime sun will be found. Also the coolest temperatures and
weakest diurnal swings.

Over the northern Columbia basin and many of the valleys of
northeast Washington and north Idaho a regime of overnight and
morning fog and low clouds with at least partial sunshine in the
afternoons and evenings look plausible...with the protected
valleys north of the basin slowest to scrub each day.

On or about Thursday models are coming into loose agreement on
breaking down or at least substantially weakening the upper ridge
with both the GFS and EC depicting a short wave passage either
Wednesday night or Thursday...followed by a more active close to
the work week with follow on waves. At this time none of these
disturbances looks particularly strong or organized...but well
worth increasing precipitation chances for valley rain and
mountain snow for late in the week. /Fugazzi

00Z TAFS: A strong cold front laying along the Pac coast at 00Z
will pass through KEAT around 06Z and through the eastern TAF
sites around 09Z. Ahead and along this front expect mainly rain
showers with possible MVFR ceilings...except a short period of
snow at KEAT then changing to rain. Ahead of the front especially
over the eastern TAF sites LLWS is expected after sunset decouples
the boundary layer until FROPA. Breezy and gusty conditions will
occur with the FROPA with precipitation quickly tapering
off...except for the Idaho Panhandle and possibly the KCOE TAF
site where upslope post-frontal showers will continue into the
morning hours. Generally decreasing winds and VFR conditions will
prevail during the day Saturday. /MJF

Area Forecast Discussion
National Weather Service Spokane WA
949 AM PST FRI FEB 5 2016

.SYNOPSIS...
Another frontal system will arrive tonight bringing rain to the
lowlands and snow to the mountains. It will become windy after
midnight tonight with gusts up to 40 mph over southeast
Washington, the Palouse, and West Plains. Dry weather and light
winds will develop on Sunday and continue through mid week as a
strong high pressure system sets up over the region.


&&

.DISCUSSION...
Updates to the forecast this morning include a bit of rework to
the pops to better resolve the light snow and rain falling from a
weaker disturbance overtopping the ridge over the area right now
ahead of the stronger wetter and gusty system passing through
overnight and Saturday. Minor adjustments to forecast high
temperatures for today and a delay in the erosion of fog in the
Columbia Basin also made. /Pelatti

&&

.AVIATION...
18Z TAFS: A weak disturbance overtopping the ridge of high
pressure over the aviation area will keep light snow and rain
along the edges of the area yet away from the TAF sites so no
mention made as far as precipitation in them for today. Some pesky
fog and low clouds are on the decrease in the Columbia Basin at
KMWH and further west to KEAT as well but as the southwest winds
increase ahead of the next weather system to pass through tonight
this fog and low cloud should decrease/erode. Next weather system
brings in mostly rain for lowland aviation sites with snow for the
mountains. Before the winds with the frontal passage mix down
there is likely to be a few hours of low level wind shear between
06Z-10Z Saturday...then after the winds mix down to allow for
gusty primarily southwest winds for the rest of the night and into
Saturday Morning...with gusts up to 40 mph at Spokane and Pullman
still. /Pelatti

lowlands and snow to the mountains. It will become windy after
midnight tonight with gusts up to 40 mph over southeast
Washington, the Palouse, and West Plains. Dry weather and light
winds will develop on Sunday and continue through mid week as a
strong high pressure system sets up over the region.

.DISCUSSION...

Today: The timing of our front has been delayed. As of 2 AM,
satellite imagery showed the front well off the coast. The evening
model runs depict a rather narrow plume of deep layer moisture
with this front, and the majority of the moisture will not cross
the Cascades until this evening. Some light bands of precipitation
will be possible today over the Idaho Panhandle and along the East
Slopes of the Cascades, but this precipitation will have minimal
impact on travel. Afternoon temperatures have been raised a few
degrees in north central Washington and along the East Slopes of
the Cascades with the slower precipitation timing. Mid to upper
30s will be possible for Omak, Brewster, Chelan and Leavenworth.
Afternoon temperatures may influence precipitation type this
evening with a mix of rain and snow for the aforementioned
communities.

Tonight into Saturday: Precipitation amounts have trended
downward with tonight`s cold front. It may be tough to achieve
Winter Weather Advisory criteria along the East Slopes of the
Cascades. Not only is the onset of precipitation slower, but the
precipitation duration seems to have decreased too. At this time,
it looks like 1 to 3 inches for the upper Methow Valley with
little to no accumulation for the main population areas around
Lake Chelan and the upper Wenatchee Valley. The communities of
Leavenworth, Plain, and Chelan have been removed from the Winter
Weather Advisory. Further east, snow levels are expected to be too
high for much accumulation below 3000 feet in northeast Washington
and north Idaho. This quick hitting system looks to produce 2 to 4
inches of accumulation in the mountains along the Canadian border
with 3 to 6 possible for the mountains of Shoshone county by
Saturday morning.

In all likelihood, the winds along and behind the cold front will
be the most noticeable weather change Friday night into Saturday.
Model soundings suggest the potential for wind gusts around 40 mph
for the Palouse, Blue Mountains, Ritzville area, and West Plains
early Saturday morning. The pre-dawn hours typically don`t favor
strong mixing, but strong mid and low level cold advection should
promote gusty conditions over the rising terrain of the Upper
Columbia Basin, Palouse, and West Plains. The pressure gradient
and 850mb winds will slacken through the day on Saturday, but
breezy conditions will be common through the afternoon over the
open country of eastern Washington and north Idaho. Exposed ridges
at ski resorts will be gusty as well, especially in the morning.

Sunday: Winds will be much lighter on Sunday as strong high
pressure quickly builds along the West Coast. The temperature
forecast starting Sunday will be tough. Temperatures aloft will
begin warming under the building ridge. Areas without fog or low
clouds will have the potential to be mild. /GKoch

Sunday night through Thursday...A strong upper ridge builds Monday
and Tuesday. This will result in mild conditions with mostly clear
skies in the mountains...and for the Palouse and Lewiston area
courtesy of downslope east-southeast boundary layer winds off the
Clearwaters. Elsewhere the forecast is more uncertain. The
strength of the ridge this time of the year will lead to a good
chance of valley fog and stratus forming at night. Sunday night
may not feature as much development however due to mid and high
clouds over the area. Then as the ridge moves squarely over the
region Monday night into Tuesday night should see coverage of fog
and stratus increase. Whether this lingers into the afternoon will
depend on the depth of the stratus. Given the higher February sun
angle forecast is leaning towards some breaks in the clouds in the
afternoon with high temperatures for most valleys reaching the low
to mid 40s. Sunshine for the Pullman and Lewiston areas should
allow high temperatures to warm into the lower 50s. The ridge
breaks down Wednesday night allowing a weak short wave trough to
pass through into Thursday bringing with it a chance for light
rain with snow levels mainly between 5000-6000 feet. JW

&&

.AVIATION...
12Z TAFS: A ragged and disorganized low cloud deck is over central
and eastern Washington this morning. With thick high clouds on the
satellite, it is tough to see the extent of the low stratus deck.
With the approaching fronal system, increasing east or southeast
low level winds should produce downslope winds around Pullman this
morning. The stratus should erode over the Palouse early this
morning, and the NAM and GFS disperse the low stratus at Spokane
and Coeur d`Alene by mid day. The passage of a vigorous cold front
tonight will produce rain and mountain snow. Precipitation amounts
don`t look particularly impressive, but a good deal of wind will
accompany the passage of the front with gusts up to 40 mph at
Spokane and Pullman. /GKoch

downward with tonight`s cold front. It may be tough to achieve
Winter Weather Advisory criteria along the East Slopes of the
Cascades. Not only is the onset of precipitation slower, but the
precipitation duration seems to have decreased too. At this time,
it looks like 1 to 3 inches for the upper Methow Valley with
little to no accumulation for the main population areas around
Lake Chelan and the upper Wenatchee Valley. The communities of
Leavenworth, Plain, and Chelan have been removed from the Winter
Weather Advisory. Further east, snow levels are expected to be too
high for much accumulation below 3000 feet in northeast Washington
and north Idaho. This quick hitting system looks to produce 2 to 4
inches of accumulation in the mountains along the Canadian border
with 3 to 6 possible for the mountains of Shoshone county by
Saturday morning.

In all likelihood, the winds along and behind the cold front will
be the most noticeable weather change Friday night into Saturday.
Model soundings suggest the potential for wind gusts around 40 mph
for the Palouse, Blue Mountains, Ritzville area, and West Plains
early Saturday morning. The pre-dawn hours typically don`t favor
strong mixing, but strong mid and low level cold advection should
promote gusty conditions over the rising terrain of the Upper
Columbia Basin, Palouse, and West Plains. The pressure gradient
and 850mb winds will slacken through the day on Saturday, but
breezy conditions will be common through the afternoon over the
open country of eastern Washington and north Idaho. Exposed ridges
at ski resorts will be gusty as well, especially in the morning.

Sunday: Winds will be much lighter on Sunday as strong high
pressure quickly builds along the West Coast. The temperature
forecast starting Sunday will be tough. Temperatures aloft will
begin warming under the building ridge. Areas without fog or low
clouds will have the potential to be mild. /GKoch

Sunday night through Thursday...A strong upper ridge builds Monday
and Tuesday. This will result in mild conditions with mostly clear
skies in the mountains...and for the Palouse and Lewiston area
courtesy of downslope east-southeast boundary layer winds off the
Clearwaters. Elsewhere the forecast is more uncertain. The
strength of the ridge this time of the year will lead to a good
chance of valley fog and stratus forming at night. Sunday night
may not feature as much development however due to mid and high
clouds over the area. Then as the ridge moves squarely over the
region Monday night into Tuesday night should see coverage of fog
and stratus increase. Whether this lingers into the afternoon will
depend on the depth of the stratus. Given the higher February sun
angle forecast is leaning towards some breaks in the clouds in the
afternoon with high temperatures for most valleys reaching the low
to mid 40s. Sunshine for the Pullman and Lewiston areas should
allow high temperatures to warm into the lower 50s. The ridge
breaks down Wednesday night allowing a weak short wave trough to
pass through into Thursday bringing with it a chance for light
rain with snow levels mainly between 5000-6000 feet. JW

.AVIATION...
06Z TAFS: The increase of mid/high clouds are masking the erratic
behavior of the stratus and fog this evening on satellite. After
the partial clearing across the eastern TAF sites early this
evening, the IFR conditions are returning especially under the
light winds, surface high over northeast Washington and narrow dewpoint
depressions. This is especially true for the KGEG-KCOE corridor.
Occasional MVFR cigs will be near KPUW, while models suggest a
return of LIFR cigs near KMWH-KEAT toward 12z. A weak warm front
will lift through the region overnight and may produce light
flurries, which may help reinforce the moist cloud deck
overnight. Clearing will be difficult to gauge toward 18z, but an
increase in southeast winds will help promote mixing into the
afternoon from the Palouse toward the KGEG and KEAT areas. A cold
front will push east of the Cascades before 00z and track across
the region during the evening. Rain will be a good bet at the TAFs
sites especially between 00z-06z. /rfox.

.SYNOPSIS...
Another frontal system will arrive tonight bringing rain to the
lowlands and snow to the mountains. It will become windy after
midnight tonight with gusts up to 40 mph over southeast
Washington, the Palouse, and West Plains. Dry weather and light
winds will develop on Sunday and continue through mid week as a
strong high pressure system sets up over the region.

&&

.DISCUSSION...

Today: The timing of our front has been delayed. As of 2 AM,
satellite imagery showed the front well off the coast. The evening
model runs depict a rather narrow plume of deep layer moisture
with this front, and the majority of the moisture will not cross
the Cascades until this evening. Some light bands of precipitation
will be possible today over the Idaho Panhandle and along the East
Slopes of the Cascades, but this precipitation will have minimal
impact on travel. Afternoon temperatures have been raised a few
degrees in north central Washington and along the East Slopes of
the Cascades with the slower precipitation timing. Mid to upper
30s will be possible for Omak, Brewster, Chelan and Leavenworth.
Afternoon temperatures may influence precipitation type this
evening with a mix of rain and snow for the aforementioned
communities.

Tonight into Saturday: Precipitation amounts have trended
downward with tonight`s cold front. It may be tough to achieve

.SYNOPSIS...
Scattered snow showers will continue through the night over the
mountains of Idaho, while areas of low clouds and fog will persist
across north Idaho. Another system will bring rain and mountain
snow Friday night into Saturday. Breezy to windy conditions are
expected to occur late Friday into Saturday especially across
southeast Washington. Strong high pressure will bring several
days of dry and somewhat mild weather Sunday into the middle part
of next week.

&&

.DISCUSSION...
Radar shows the snow showers decreasing rapidly across the central
Idaho Panhandle as more stable conditions develop and loss of
daytime heating has reduced the low level instability showers.
These more stable conditions are due to an incoming ridge of high
pressure aloft which is accompanied with plenty of mid and high
level moisture. This will give way to cloudy conditions overnight,
mainly aloft but pockets of fog and areas of stratus will still be
an issue. Overnight, a weak mid level warm front will sweep
through the region. The reflection of this mid level boundary can
be seen on the radar loop across the Cascades. This feature is
expected to push toward the Canadian border overnight with
isolated snow showers possible. Meanwhile, surface winds will
remain light through the night and temperatures hover around
freezing. /rfox.

00Z TAFS: Sunshine and increased winds have eroded much, if not
all, of the stratus and fog over a good portion of the lowlands in
and around the edges of the Columbia Basin...yet some still
stubbornly lingers in the valleys and such. Expectation is as we
cool overnight and the ridge moves in further and amplifies that
the stratus and low cloud will reform again. Minor weather
disturbances will overtop the ridge and bring light snow showers
for the most part until the leading edge of a stronger weather
system starts to influence the aviation area from about KMWH and
KEAT with rain. Rain and snow or all snow is likely for most other
portions of the East Slopes of the North Cascades North of KEAT.
Additionally the low level southeast wind should help to erode the
stratus and fog before the onset of the precipitation associated
with this incoming weather system. /Pelatti
