Area Forecast Discussion
National Weather Service Spokane WA
432 AM PDT THU SEP 18 2014

.SYNOPSIS...
A weak cold front will move through Washington and Idaho today.
The front will push temperatures closer to normal and bring the
potential for widely scattered showers. A strong high pressure
ridge will return Friday and promote warm and dry weather through
the weekend. High temperatures Sunday should be ten degrees above
normal. The breakdown of this ridge...and a return to cooler
conditions...will begin Monday. However...precipitation is not
expected until late Tuesday or Wednesday for most towns.

&&

.DISCUSSION...
Today and Tonight...Scattered showers will develop across the
Inland Northwest today as moisture continues to stream into the
region from the southwest. So far the light radar returns on
regional radar mosaic have not resulted in any precipitation
reports from observation sites across the forecast area. The dry
lower levels of the atmosphere, as seen on 00Z OTX sounding, will
take a while to moisten up. The best chance of showers across the
area will be this afternoon as the cold front and shortwave trough
slide across the region. Modest instability may allow isolated
thunderstorms to develop across extreme eastern WA and the
panhandle of Idaho. As daytime instability increases this
afternoon, bulk shear decreases substantially so organized storm
cells are not anticipated. Winds will increase behind the cold
front, with gusts of 25 to 30 mph common from the Cascade gap
valleys, across the basin and into the Palouse and west plains.
Daytime temperatures will be somewhat cooler for the western zones
but pretty close to Wednesday`s readings for extreme eastern WA
and north Idaho. Overnight temperatures tonight will remain above
normal thanks to gusty winds behind the front. /Kelch

Fri through Mon Nt: With a rapidly building upper ridge Fri
through the weekend, we`re not expecting any pcpn as large-scale
subsidence/warming aloft accompanies clear skies and light winds.
Fri morning should be the coolest morning, with some NE Wa and N
Idaho valleys seeing some patchy fog. The warmest day should be
Sunday with high temps generally in the 80s... 10 degrees warmer
than normal for a number of towns. The breakdown of the
ridge...and the approach of a strong Ern Pacific trough...still
looks to be on track for the Mon through Tue time frame. Based on
trends in model guidance, the lack of sufficient instability, and
a deep sub-cloud dry lyr, the first minor wave that ejects from
the offshore trough Tues morning is not expected to produce any
pcpn outside of the mtns across the E Slopes of the Cascades.bz

Tuesday through Thursday: A cold front will be pushing through the
region during this period bringing a small taste of autumn along
with it. Poor consistency among the models is keeping the exact
timing of the front a little unclear. It is expected to a chance
of precip to the entire Inland Northwest and temperatures will
decrease around 10 degrees from the beginning of the period. /JDC

&&

.AVIATION...
12Z TAFS: A moist southwest flow and incoming cold front/upper
trough impact the Inland NW, providing increased cloud cover and
the threat of a few showers. The best shower chances will be near
the Cascades, including KEAT, and over the northeast mountains
today. Showers will also develop in the vicinity of KGEG to KCOE
in the afternoon with the passing front. There is also a slight
risk for -tsra to develop across the mountains of far eastern WA
and north ID from about 18Z-03Z. Expect increased winds this
afternoon, with gusts in the 20 to 25kt range, locally higher near
KEAT. Winds will gradually abate after 02-04Z Friday. /EK

.DISCUSSION...
Evening update: tracking a jet streaking coming up through
CA/southern OR and projected to advance toward northeast
OR/southeast WA/central ID late overnight into Thursday morning.
Both the HRRR and NAM Hi-Res have been indicating some shower
threat expanding up through south-central/eastern OR and southern
ID the Blues/Camas Prairie and Central Panhandle between 09Z and
15 or 18Z Thursday (late overnight into Thursday morning). Some
guidance suggest perhaps as far northwest as the Pullman area, but
confidence is not great enough to go that far north. I wouldn`t be
surprised to see some sprinkles that far north though. Overall I
increased PoPs and sky cover over southeast WA through the central
Panhandle. I kept some mention of smoke in that region through
early overnight before the potential shower threat will less than
threat. But this will continue to be assessed. Otherwise the
forecast looks on track and overall the precipitation that comes
with this system still does not look overwhelming. /J. Cote`

.SYNOPSIS...
A weak cold front will move through Washington and Idaho on
Thursday. The front will push temperatures closer to normal and
bring the potential for widely scattered showers on Thursday. A
high pressure ridge will return Friday and promote warm and dry
weather through the weekend.


&&

.DISCUSSION...
Evening update: tracking a jet streaking coming up through
CA/southern OR and projected to advance toward northeast
OR/southeast WA/central ID late overnight into Thursday morning.
Both the HRRR and NAM Hi-Res have been indicating some shower
threat expanding up through south-central/eastern OR and southern
ID the Blues/Camas Prairie and Central Panhandle between 09Z and
15 or 18Z Thursday (late overnight into Thursday morning). Some
guidance suggest perhaps as far northwest as the Pullman area, but
confidence is not great enough to go that far north. I wouldn`t be
surprised to see some sprinkles that far north though. Overall I
increased PoPs and sky cover over southeast WA through the central
Panhandle. I kept some mention of smoke in that region through
early overnight before the potential shower threat will less than
threat. But this will continue to be assessed. Otherwise the
forecast looks on track and overall the precipitation that comes
with this system still does not look overwhelming. /J. Cote`

&&

.AVIATION...
00Z TAFS: A moist southwest flow and approaching cold front/upper
trough will impact the Inland NW over the next 24 or so hours. The
system appears to stretch and split moving inland, but will still
provide some increased cloud cover and the threat of a few
showers. The best shower chances will be near the Cascades,
including EAT, and over the northeast mountains going into later
tonight into Thursday. There is a small threat near the GEG to COE
and PUW/LWS sites, but the risk is still low to mention in the
TAF. There is also the potential for a few thunderstorms across
the NE MTNS of WA and north ID, but the risk for this is also low.
As the front pushes through look for increased winds Thursday
afternoon, with gusts in the 20 to 25kt range. Lastly, smoke from
nearby wildfires will locally reduce visibilities to MVFR
conditions near PUW/LWS this evening, possibly into the morning,
but guidance suggests its intensity wanes over Wednesday evening.

.SYNOPSIS...
A weak cold front will move through Washington and Idaho on
Thursday. The front will push temperatures closer to normal and
bring the potential for widely scattered showers on Thursday. A
high pressure ridge will return Friday and promote warm and dry
weather through the weekend.

&&

.DISCUSSION...
Tonight and Thursday: A trough of low pressure will push across
the region over the next 24 to 36 hours. Satellite imagery shows
this trough located just offshore at 130W longitude. Moisture
streaming into the region out ahead of the trough has resulted in
a steady dose of mid to level clouds with some occasional
sprinkles observed toward the Cascade Mtns. The trough is
currently undergoing some splitting with the bulk of the upper
level dynamics remaining south heading toward California. The
northern branch of this system will weaken as it slowly crosses
into eastern WA tonight into Thursday. Best chances for showers
tonight will be in the Cascade Mtns over into the Okanogan
Highlands. Showers chances will increase further east across the
Northeast Mtns and in the ID Panhandle during the day on Thursday.
Models do not show much moistening of the lower levels across the
basin with this system, so not expecting much more than some
thickening mid level clouds across these areas; there will be a
good chance that this will be the case across the Spokane Area and
on the Palouse as well. I left a slight chance for thunderstorms
in the Northeast Mtns and in the Panhandle for Thursday afternoon,
but models show only some weak instability, so chances for
thunderstorms are marginal at best. Winds will be breezy tomorrow
with sustained winds of 10-15 mph and gusts up to around 20 mph
expected. Temperatures will be cooler tomorrow compared to today
with highs in the mid 70s to mid 80s. /SVH

Thursday night through Sunday...The evolution and ejection of the
deep upper level trough currently visible off the off the Pacific
coast will impact the first part of the forecast period. latest
models are in good agreement in splitting this feature as it moves
inland...subjecting the forecast area to a weaker northern branch
short wave transit Thursday night with a follow-on dying wave on
Friday. neither of these features is very impressive with dynamic
support...although precipitable water values will be adequate for
shower development with orographic lift over favored terrain.

Thus...low chance/scattered precipitation chances are warranted
over the Idaho Panhandle and Cascades with the first(stronger)
wave and merely Slight chance/isolated pops for a few showers with
the second wave on Friday. Weak instability is also noted with the
first wave due to the residual cold pool aloft on Thursday
evening...enough for a mention of brief and weak thunderstorms
during the evening hours over the Idaho Panhandle.

After that...Late Friday through Sunday...a new and solid upper
level ridge takes over again leading to dry and warming
conditions throughout the region.

Temperatures through this period will remain above normal with
only a weak moderating influence with Thursday`s and Friday`s
wave passages. Winds will be predominantly westerly and locally
breezy near the Cascades Thursday evening and into Friday before
switching back to the northeast by Saturday and Sunday. /Fugazzi

Sunday Night through Wednesday: Strong upper level ridge starts to
shift east Sunday night into Monday. Models are of course
disagreeing with the timing of the breakdown of the ridge. For now
have trended more towards the ECMWF which is slower in bringing
the next weather system onshore. Have a slight chance of precip in
the Cascades Monday night and Tuesday and then bring widespread
slight chance to chance of precip into the area for Tuesday night
and Wednesday. Models are hinting at quite a big trough moving
into the Pacific Northwest starting Tuesday. As such have
increased our cloud cover quite a bit starting Monday night...with
further increase in clouds likely. A cold front looks to pass Tue
night/Wed morning with high temps dropping about 10 degrees from
Tue to Wed. The only other big changes made was increased mountain
temperatures for Sunday night and Monday night given the strength
of the ridge. Temps in the mid 50s to mid 60s is quite likely in
the mtns. In response to the warmer mtn temps, overnight relative
humidities will be pretty low in the mtns as well. /Nisbet

Area Forecast Discussion
National Weather Service Spokane WA
222 PM PDT WED SEP 17 2014

.SYNOPSIS...
A weak cold front will move through Washington and Idaho on
Thursday. The front will push temperatures closer to normal and
bring the potential for widely scattered showers on Thursday. A
high pressure ridge will return Friday and promote warm and dry
weather through the weekend.

&&

.DISCUSSION...
Tonight and Thursday: A trough of low pressure will push across
the region over the next 24 to 36 hours. Satellite imagery shows
this trough located just offshore at 130W longitude. Moisture
streaming into the region out ahead of the trough has resulted in
a steady dose of mid to level clouds with some occasional
sprinkles observed toward the Cascade Mtns. The trough is
currently undergoing some splitting with the bulk of the upper
level dynamics remaining south heading toward California. The
northern branch of this system will weaken as it slowly crosses
into eastern WA tonight into Thursday. Best chances for showers
tonight will be in the Cascade Mtns over into the Okanogan
Highlands. Showers chances will increase further east across the
Northeast Mtns and in the ID Panhandle during the day on Thursday.
Models do not show much moistening of the lower levels across the
basin with this system, so not expecting much more than some
thickening mid level clouds across these areas; there will be a
good chance that this will be the case across the Spokane Area and
on the Palouse as well. I left a slight chance for thunderstorms
in the Northeast Mtns and in the Panhandle for Thursday afternoon,
but models show only some weak instability, so chances for thunderstorms
are marginal at best. Winds will be breezy tomorrow with sustained
winds of 10-15 mph and gusts up to around 20 mph expected. Temperatures
will be cooler tomorrow compared to today with highs in the mid
70s to mid 80s. /SVH

Thursday night through Sunday...The evolution and ejection of the
deep upper level trough currently visible off the off the Pacific
coast will impact the first part of the forecast period. latest
models are in good agreement in splitting this feature as it moves
inland...subjecting the forecast area to a weaker northern branch
short wave transit Thursday night with a follow-on dying wave on
Friday. neither of these features is very impressive with dynamic
support...although precipitable water values will be adequate for
shower development with orographic lift over favored terrain.

Thus...low chance/scattered precipitation chances are warranted
over the Idaho Panhandle and Cascades with the first(stronger)
wave and merely Slight chance/isolated pops for a few showers with
the second wave on Friday. Weak instability is also noted with the
first wave due to the residual cold pool aloft on Thursday
evening...enough for a mention of brief and weak thunderstorms
during the evening hours over the Idaho Panhandle.

After that...Late Friday through Sunday...a new and solid upper
level ridge takes over again leading to dry and warming
conditions throughout the region.

Temperatures through this period will remain above normal with
only a weak moderating influence with Thursday`s and Friday`s
wave passages. Winds will be predominantly westerly and locally
breezy near the Cascades Thursday evening and into Friday before
switching back to the northeast by Saturday and Sunday. /Fugazzi

Sunday Night through Wednesday: Strong upper level ridge starts to
shift east Sunday night into Monday. Models are of course
disagreeing with the timing of the breakdown of the ridge. For now
have trended more towards the ECMWF which is slower in bringing
the next weather system onshore. Have a slight chance of precip in
the Cascades Monday night and Tuesday and then bring widespread
slight chance to chance of precip into the area for Tuesday night
and Wednesday. Models are hinting at quite a big trough moving
into the Pacific Northwest starting Tuesday. As such have
increased our cloud cover quite a bit starting Monday night...with
further increase in clouds likely. A cold front looks to pass Tue
night/Wed morning with high temps dropping about 10 degrees from
Tue to Wed. The only other big changes made was increased mountain
temperatures for Sunday night and Monday night given the strength
of the ridge. Temps in the mid 50s to mid 60s is quite likely in
the mtns. In response to the warmer mtn temps, overnight relative
humidities will be pretty low in the mtns as well. /Nisbet

.AVIATION...
18Z TAFS: High pressure shifts east and the southwest flow brings
moisture and energy up from the south today. A cold front will
move through the forecast area Thursday. Middle and high level
clouds will thicken with a slight chance of showers for the
Cascades. A few sprinkles may slip by EAT after 06Z Thursday.
Some smoke from near wildfires may lower VIS toward MVFR
conditions around PUW and LWS Wednesday morning. Otherwise look
for VFR, dry conditions. /MJF

.DISCUSSION...
Today through Thursday night...The weather pattern will become
more unsettled across the Inland Northwest as the ridge of high
pressure gets nudged to the east by an approaching upper trough.
Regional radar imagery shows some light returns moving northeast
across western WA this morning. The trajectory is more north than
east so shower activity is expected to remain close to the Cascade
crest today although there may be some sprinkles for the Wenatchee
area and the Okanogan Highlands today. The energy associated with
this system is splitting, with the bulk of it remaining in the
southern stream as a low closes off and drifts south along the
west coast. The secondary northern stream will eventually slide
east tonight, bringing some showers to the northern mountains. The
better chance for showers and even a few thunderstorms will be
across the eastern half of the forecast area on Thursday. The
north-south orientation of the trough will allow the very warm air
to remain in place today. Max temperatures will be close to
Tuesdays readings, which are about 10m degrees above seasonal
normals. A cold front will move through late in the day Thursday
bringing cooler conditions but the timing will mean one more day
of above normal temps. Breezy conditions will develop behind the
front with gusts to around 25 mph across the basin. Drier air
behind the front will limit any lingering showers to the Idaho
panhandle Thursday night. /Kelch

Friday through Sunday: The models are in very good agreement
Friday through the weekend...developing a rex block type feature
over the Western U.S. Some residual mid-level moisture in the
northwest flow may produce a small chance for showers over the
mountains of the north Idaho Panhandle and Cascade Crest on Friday.
However, model soundings suggest warming and drying aloft will
limit precipitation chances to the morning hours. Increasing 500mb
heights Friday afternoon into the weekend will shunt the storm
track well north of the region. Above average temperatures will
return by Saturday. Afternoon readings in the upper 70s to mid 80s
will be common Saturday, and Sunday will likely feature mid 80s to
upper 80s. The last weekend on the official summer calendar will
actually feel like summer. Fall officially arrives on Monday the
22nd with the autumn equinox. /GKoch

Monday through Wednesday: This is shaping up to be a transition
period for the region as a trough system will begin to press into
the region from the Gulf of Alaska. The ridge pattern will linger
over the region Monday through Tuesday. This will allow for
precip free period. By late Tuesday, the ridge begins to breakdown
and moisture begins to push over the Cascades area. The precip
will continue to cross the Inland Northwest into through
Wednesday. Winds are expected to become breezy as the trough
moves through the region. Temperatures are expected to decrease
to near season normals. /JDC

Area Forecast Discussion
National Weather Service Spokane WA
248 AM PDT WED SEP 17 2014

.SYNOPSIS...
Another warm day is in store for the Inland Northwest with
afternoon temperatures in the 80s. A weak cold front will move
through Washington and Idaho on Thursday. The front will push
temperatures closer to normal and bring the potential for widely
scattered showers on Thursday. A high pressure ridge will return
Friday and promote warm and dry weather through the weekend.


&&

.DISCUSSION...
Today through Thursday night...The weather pattern will become
more unsettled across the Inland Northwest as the ridge of high
pressure gets nudged to the east by an approaching upper trough.
Regional radar imagery shows some light returns moving northeast
across western WA this morning. The trajectory is more north than
east so shower activity is expected to remain close to the Cascade
crest today although there may be some sprinkles for the Wenatchee
area and the Okanogan Highlands today. The energy associated with
this system is splitting, with the bulk of it remaining in the
southern stream as a low closes off and drifts south along the
west coast. The secondary northern stream will eventually slide
east tonight, bringing some showers to the northern mountains. The
better chance for showers and even a few thunderstorms will be
across the eastern half of the forecast area on Thursday. The
north-south orientation of the trough will allow the very warm air
to remain in place today. Max temperatures will be close to
Tuesdays readings, which are about 10m degrees above seasonal
normals. A cold front will move through late in the day Thursday
bringing cooler conditions but the timing will mean one more day
of above normal temps. Breezy conditions will develop behind the
front with gusts to around 25 mph across the basin. Drier air
behind the front will limit any lingering showers to the Idaho
panhandle Thursday night. /Kelch

Friday through Sunday: The models are in very good agreement
Friday through the weekend...developing a rex block type feature
over the Western U.S. Some residual mid-level moisture in the
northwest flow may produce a small chance for showers over the
mountains of the north Idaho Panhandle and Cascade Crest on Friday.
However, model soundings suggest warming and drying aloft will
limit precipitation chances to the morning hours. Increasing 500mb
heights Friday afternoon into the weekend will shunt the storm
track well north of the region. Above average temperatures will
return by Saturday. Afternoon readings in the upper 70s to mid 80s
will be common Saturday, and Sunday will likely feature mid 80s to
upper 80s. The last weekend on the official summer calendar will
actually feel like summer. Fall officially arrives on Monday the
22nd with the autumn equinox. /GKoch

Monday through Wednesday: This is shaping up to be a transition
period for the region as a trough system will begin to press into
the region from the Gulf of Alaska. The ridge pattern will linger
over the region Monday through Tuesday. This will allow for
precip free period. By late Tuesday, the ridge begins to breakdown
and moisture begins to push over the Cascades area. The precip
will continue to cross the Inland Northwest into through
Wednesday. Winds are expected to become breezy as the trough
moves through the region. Temperatures are expected to decrease
to near season normals. /JDC

&&

.AVIATION...
06Z TAFS: High pressure shifts east and the southwest flow brings
moisture and energy up from the south into Wednesday, while a cold
front approaches Wednesday night (into Thursday). Look for some
middle and high clouds, thickening especially Wednesday. A slight
chance of showers comes to the Cascades. A few sprinkles may slip
by EAT between 09-15Z, but somewhat better chances comes after
00Z Thursday (Wednesday evening) when the main system approaches.
Even then precipitation is not expected to be significant. Some
smoke from near wildfires may lower VIS toward MVFR conditions
around PUW and LWS Wednesday morning. Otherwise look for VFR, dry
conditions. /J. Cote`

The region will remain in a mild southwest flow through Wednesday,
with slight shower chances coming toward the Cascades and northern
mountains. Cooler, more seasonal temperatures follow the passage
of a weak cold front Thursday. Thursday will also be locally
breezy with a chance for light rain showers. More sunshine and

Evening update: watching some of the energy coming up through
Oregon and along the Pacific Northwest coast. Thicker clouds and
some radar returns showing up southwest of Portland and off the
Washington coast. Newest model runs, including the HRRR and the
Hi-res NAM, show some of this moisture sliding up north toward
the Cascades overnight into Wednesday morning. As such I added a
slight chance of showers toward the Cascades for after midnight,
mainly south of Lake Chelan, with the chances expanding northward
toward Canadian border by morning. Some sprinkles are possible
toward the lower elevations including the Wenatchee area,
Waterville Plateau and Okanogan Valley toward the Okanogan
Highlands as well. Otherwise I increased sky cover slightly.
Overnight lows and tomorrow afternoon`s highs generally look on

.SYNOPSIS...
Today into Wednesday will feel like summer with afternoon
temperatures in the 80s. Cooler, more seasonal temperatures will
follow the passage of a weak cold front on Thursday. Thursday
will also be locally breezy with a chance for light rain showers.
Sunshine and light winds will return on Friday, and look for warm
temperatures once again this weekend.

&&

.DISCUSSION...
Tonight and Wednesday: Currently a weak wave is still in the
process of passing through the area that has shifted our ridge of
high pressure eastward now over western Montana. This initial
eastward shift is the first hit of the eventual ridge breakdown
later in the week. As of 2pm, weak echos on radar were being
indicated on a line from Omak to Coolin and areas slightly south.
The echos were likely due to weak forcing associated with the
passing wave. Not much in the way of precipitation is reaching the
surface as indicated by observations, so the majority is likely
attributed to virga or very light showers. Moving through the
afternoon and into the evening I anticipate the wave to continue
to push north with only virga or some very light showers the
continued extent.

Overnight we can expect mainly calm conditions as we await the next
more potent storm system later Wednesday. Starting as early as
tonight we will start to see some moisture filtering in ahead of
the main system allowing for increased cloud cover. This should
help to keep our overnight temperatures from falling as much as
previous nights. Tomorrow brings another warm day to the region
as we remain firmly entrenched within the mild southwesterly flow
pattern. Overall we can expect similar conditions as today with
warm temperatures and filtered mid and high clouds. As we move
into the afternoon is when the front end of the approaching system
finally reaches the Cascades. Tomorrow afternoon is when the
mention of precipitation enters the forecast for these areas.
Overall this is a rather low impact portion of the forecast as we
await the main incoming system. /Fliehman

Wednesday night through Friday night...A splitting trough will
move through the region Wednesday night and Thursday. The best
dynamics and moisture will remain south in Oregon/NorCal with a
secondary wave area moving through central/southern B.C. The front
that will accompany the splitting trough is not overly strong.
Southwest Tuesday night and Wednesday will increase the usable
moisture with Precipitable waters going up to nearly an inch,
which is well above normal. The models have been in decent
agreement indicating the best instability and moisture will move
through my southeast zones Thursday afternoon. Showers will be
possible for all the higher terrain outside of the Columbia basin
and the Palouse...the focus will be from southern Shoshone county
then following the higher terrain north over the northern
Panhandle and west into the northeast mountains. In these area
there will be a chance of showers and the possibility of some
embedded thunderstorms. Instability parameters indicate no real
organization to the thunderstorms and we are expecting just a few
pulse type storms.

The surface gradient will tighten through the day Thursday and
the 850mb winds around 20 kts should easily mix down to the
surface. This will result in breezy southwest winds with gusts up
to 25 mph across the basin, Palouse and Spokane area.

High pressure will rebuild back into the area quickly on Friday
and Saturday. Northwest flow on Friday will keep conditions dry
with temperatures cooling down several degrees but remaining on
the warm side of normal. This will mark the beginning of a warmer
and drier period expected through the weekend. /Tobin

Saturday through Tuesday night: A brief period of northwest flow
will be replaced by another ridge of high pressure for the
weekend. This will bring warming temperatures and altogether shut
down any chances for precipitation. Temperatures will peak on
Sunday (although they will be almost as warm on Saturday) 10 to 15
degrees above normal (widespread 80s). The dry air that will
overspread the region will also allow for good cooling after the
sunsets. Temperatures will cool closer to where they should be at
night, but will warm quickly through the morning.

Changes may be on the way for next week, although it may take a
few days for it all to take effect. A large trough over the Gulf
of Alaska will transition our flow pattern to more southwest, and
a shortwave looks to move near or over the Inland Northwest in the
Monday/Tuesday time-frame. This will begin the ridge breakdown
process. How much the ridge is suppressed will determine what
happens as a more organized system moves toward the region mid-
week. Lots of time to look, but there could be higher rain chances
in the offering beginning mid next week. ty

Area Forecast Discussion

510 PM PDT TUE SEP 16 2014

.SYNOPSIS...
Today into Wednesday will feel like summer with afternoon
temperatures in the 80s. Cooler, more seasonal temperatures will
follow the passage of a weak cold front on Thursday. Thursday
will also be locally breezy with a chance for light rain showers.
Sunshine and light winds will return on Friday, and look for warm
temperatures once again this weekend.

&&

.DISCUSSION...
Tonight and Wednesday: Currently a weak wave is still in the
process of passing through the area that has shifted our ridge of
high pressure eastward now over western Montana. This initial
eastward shift is the first hit of the eventual ridge breakdown
later in the week. As of 2pm, weak echos on radar were being
indicated on a line from Omak to Coolin and areas slightly south.
The echos were likely due to weak forcing associated with the
passing wave. Not much in the way of precipitation is reaching the
surface as indicated by observations, so the majority is likely
attributed to virga or very light showers. Moving through the
afternoon and into the evening I anticipate the wave to continue
to push north with only virga or some very light showers the
continued extent.

Overnight we can expect mainly calm conditions as we await the next
more potent storm system later Wednesday. Starting as early as
tonight we will start to see some moisture filtering in ahead of
the main system allowing for increased cloud cover. This should
help to keep our overnight temperatures from falling as much as
previous nights. Tomorrow brings another warm day to the region
as we remain firmly entrenched within the mild southwesterly flow
pattern. Overall we can expect similar conditions as today with
warm temperatures and filtered mid and high clouds. As we move
into the afternoon is when the front end of the approaching system
finally reaches the Cascades. Tomorrow afternoon is when the
mention of precipitation enters the forecast for these areas.
Overall this is a rather low impact portion of the forecast as we
await the main incoming system. /Fliehman

Wednesday night through Friday night...A splitting trough will
move through the region Wednesday night and Thursday. The best
dynamics and moisture will remain south in Oregon/NorCal with a
secondary wave area moving through central/southern B.C. The front
that will accompany the splitting trough is not overly strong.
Southwest Tuesday night and Wednesday will increase the usable
moisture with Precipitable waters going up to nearly an inch,
which is well above normal. The models have been in decent
agreement indicating the best instability and moisture will move
through my southeast zones Thursday afternoon. Showers will be
possible for all the higher terrain outside of the Columbia basin
and the Palouse...the focus will be from southern Shoshone county
then following the higher terrain north over the northern
Panhandle and west into the northeast mountains. In these area
there will be a chance of showers and the possibility of some
embedded thunderstorms. Instability parameters indicate no real
organization to the thunderstorms and we are expecting just a few
pulse type storms.

The surface gradient will tighten through the day Thursday and
the 850mb winds around 20 kts should easily mix down to the
surface. This will result in breezy southwest winds with gusts up
to 25 mph across the basin, Palouse and Spokane area.

High pressure will rebuild back into the area quickly on Friday
and Saturday. Northwest flow on Friday will keep conditions dry
with temperatures cooling down several degrees but remaining on
the warm side of normal. This will mark the beginning of a warmer
and drier period expected through the weekend. /Tobin

Saturday through Tuesday night: A brief period of northwest flow
will be replaced by another ridge of high pressure for the
weekend. This will bring warming temperatures and altogether shut
down any chances for precipitation. Temperatures will peak on
Sunday (although they will be almost as warm on Saturday) 10 to 15
degrees above normal (widespread 80s). The dry air that will
overspread the region will also allow for good cooling after the
sunsets. Temperatures will cool closer to where they should be at
night, but will warm quickly through the morning.

Changes may be on the way for next week, although it may take a
few days for it all to take effect. A large trough over the Gulf
of Alaska will transition our flow pattern to more southwest, and
a shortwave looks to move near or over the Inland Northwest in the
Monday/Tuesday time-frame. This will begin the ridge breakdown
process. How much the ridge is suppressed will determine what
happens as a more organized system moves toward the region mid-
week. Lots of time to look, but there could be higher rain chances
in the offering beginning mid next week. ty

.AVIATION...
00Z TAFS: High pressure shifts east and the southwest flow brings
moisture and energy up from the south. Look for some middle and
high clouds, thickening especially Wednesday. A slight chance of
showers comes toward the Cascades...mainly after 12-18Z. Some
smoke from nearby wildfires may also lower VIS toward MVFR
conditions, mainly around PUW and LWS Wednesday morning. Otherwise
look for VFR, dry conditions. /J. Cote`

continue to drift north, expect a gradual clearing through the day
and overnight. Our next approaching system will have clouds on the

.DISCUSSION...

Today through Wednesday night...Ridge deamplification and
propagation of the ridge axis eastward continues during this time
interval. This opens up the door for approach of shortwave
disturbances from the South and Southwest. Elevated moderate
instability and moisture merit continued mention of sprinkles in
the forecast roughly south and east of a line from Ritzville to
Plummer. Wednesday into Wednesday night the ridge is displaced
even further east in Montana and the flow becomes more southerly
as an offshore low pressure system works its way to northwest and
towards the coast. This necessitates continued mention of showers
along the cascades and up north near the British Columbia border.
As to be expected with the loss of the ridge a slight cooling
trend with increase cloud cover remains. Additionally the winds
should prevail more from the south tonight and Wednesday. /Pelatti

Thursday: The most active weather day of the week should be
Thursday following the passage of a weak cold front Wednesday
night. It is tough to get too excited about much significant
shower activity Thursday. The 0z models agree that the incoming
500mb trough will move inland in pieces with the low amplitude
northern branch shortwave tracking along the U.S/Canadian border
and the moisture rich southern branch wave moving through
California. The NAM and GFS forecast the best combination of mid-
level instability and surface based CAPE over the Idaho Panhandle
Thursday afternoon. Our forecast includes a slight chance of
thunderstorms for places like Bonners Ferry, Sandpoint, Kellogg,
and St Maries. Marginal instability and weak deep layer shear
suggest that any convective cells will be rather unorganized. At
this time, the threat of strong storms looks to be very low.

Breezy west winds should develop Thursday afternoon through the
Cascade gaps, Columbia Basin, Palouse and West Plains. 850mb winds
in the 20-25kt range suggest that gusts will top out close to
25mph in the afternoon and early evening.

Friday: A transition to a drier northwest flow in the 700-500mb
layer is expected to occur on Friday and Saturday. There may be
enough shallow mid-level instability on Friday for widely
scattered showers over the mountains of the Idaho Panhandle and
along the Cascade Crest. Elsewhere, fair weather cumulus and near
normal temperatures should be the norm on Friday.

Saturday through Monday: A return of high pressure ridging over
the weekend will bring sunshine, warm temperatures, and light
winds to the region. The dry air mass, light winds, and
increasingly long nights will promote large diurnal temperature
swings. Chilly nights and warm afternoons. /GKoch

northern branch shortwave tracking along the U.S/Canadian border
and the moisture rich southern branch wave moving through
California. The NAM and GFS forecast the best combination of mid-
level instability and surface based CAPE over the Idaho Panhandle
Thursday afternoon. Our forecast includes a slight chance of
thunderstorms for places like Bonners Ferry, Sandpoint, Kellogg,
and St Maries. Marginal instability and weak deep layer shear
suggest that any convective cells will be rather unorganized. At
this time, the threat of strong storms looks to be very low.

Breezy west winds should develop Thursday afternoon through the
Cascade gaps, Columbia Basin, Palouse and West Plains. 850mb winds
in the 20-25kt range suggest that gusts will top out close to
25mph in the afternoon and early evening.

Friday: A transition to a drier northwest flow in the 700-500mb
layer is expected to occur on Friday and Saturday. There may be
enough shallow mid-level instability on Friday for widely
scattered showers over the mountains of the Idaho Panhandle and
along the Cascade Crest. Elsewhere, fair weather cumulus and near
normal temperatures should be the norm on Friday.

Saturday through Monday: A return of high pressure ridging over
the weekend will bring sunshine, warm temperatures, and light
winds to the region. The dry air mass, light winds, and
increasingly long nights will promote large diurnal temperature
swings. Chilly nights and warm afternoons. /GKoch

.AVIATION...
18Z TAFS: Moisture advecting into the region from the south has
resulted in bands of mid and high level clouds draping across much
of the region this morning. Some obs have shown traces of precip
with these, but that will be about the extent. As these clouds
continue to drift north, expect a gradual clearing through the day
and overnight. Our next approaching system will have clouds on the
increase once again after mainly 12Z tomorrow. VIS has been
reduced at times at KPUW due to smoke passing through the area.
Expect this to lift this afternoon as the atmosphere becomes
better mixed promoting VFR conditions. /Fliehman

.SYNOPSIS...
Today into Wednesday will feel like summer with afternoon
temperatures in the 80s. Cooler, more seasonal temperatures will
follow the passage of a weak cold front on Wednesday night.
Thursday will be locally breezy with a chance for light rain
showers. Sunshine and light winds will return on Friday, and look
for warm temperatures once again this weekend.

&&

.DISCUSSION...

Today through Wednesday night...Ridge deamplification and
propagation of the ridge axis eastward continues during this time
interval. This opens up the door for approach of shortwave
disturbances from the South and Southwest. Elevated moderate
instability and moisture merit continued mention of sprinkles in
the forecast roughly south and east of a line from Ritzville to
Plummer. Wednesday into Wednesday night the ridge is displaced
even further east in Montana and the flow becomes more southerly
as an offshore low pressure system works its way to northwest and
towards the coast. This necessitates continued mention of showers
along the cascades and up north near the British Columbia border.
As to be expected with the loss of the ridge a slight cooling
trend with increase cloud cover remains. Additionally the winds
should prevail more from the south tonight and Wednesday. /Pelatti

Area Forecast Discussion
National Weather Service Spokane WA
1025 PM PDT MON SEP 15 2014

.SYNOPSIS...
Unseasonably warm temperatures will be across the Inland Northwest
through Wednesday as high pressure remains over the region. A weak
cold front will likely arrive on Thursday cooling temperatures
closer to normal. There will also be a chance for light mountain showers
Thursday into Friday morning with the passing front. Warm and dry
conditions will likely return for the weekend.

&&

.DISCUSSION...
Tonight and Tuesday: High pressure will be over the region for the
next 24 hours, although it will weaken slightly as a shortwave off
the Oregon coast pivots into it. A band of high level moisture
associated with the shortwave will sweep in from the south
overnight into Tuesday. The lift is weak especially as the
shortwave falls apart as it tracks into the upper ridge axis
position. Most of this moisture will be above 10k ft, so the
threat of any precipitation will be minor. But the best if any
chance will be across the Blue mountains Tuesday morning and then
into central ID panhandle by Tuesday afternoon. Otherwise
anticipate some areas of virga or isolated sprinkles with the
cloud band across southeast Washington and southern Idaho
panhandle. Meanwhile, low level temperatures will continue to
rise, about 2 to 4 degrees warmer on Tuesday. This would make
Tuesday the warmest day of the week. Winds will be light and
mostly east/northeast tonight into Tuesday morning, with southwest
winds creeping into the southern Columbia Basin and Palouse by
Tuesday afternoon. /rfox

Tuesday night through Thursday night...In the big picture a
splitting trough will move into the eastern Pacific by Tuesday
afternoon. By Wednesday afternoon the southern portion of the
split closes into a cut-off low with the best moisture and
dynamics staying well south of our area. What this will do is drag
a weakening trough through southern B.C. Wednesday night and
Thursday with best forcing staying in central B.C. There will be
some mid level moisture that will move into the area Wednesday
night and Thursday.

For Tuesday night the models keep showing a weak wave moving
out of northeast Oregon and just brushing our southeast zones.
I kept some very low end pops through the night, but am far from
impressed and thinking at this just may be some increasing mid-
level clouds.

Wednesday night through Thursday night...Slight chance to chance
pops over the Cascades Wednesday night...then the chance for
precipitation will track across the northern mountains and Idaho
Panhandle for Thursday and Thursday night. Precipitation as mainly
showers... however there appears to be enough mid level
instability to introduce a few lighting strikes for the far
northeast mountains and Idaho Panhandle zones late in the day
Thursday. Confidence is much better for some light shower than any
lightning. Any precipitation should be a tenth or less. A slight
up tick in the southwest winds can also be expected Thursday
afternoon with sustained winds around 10mph. /Tobin

Friday afternoon through Tuesday morning: The exiting mid-week
trough will be replaced by another ridge of high pressure for the
weekend. While the ridge looks to keep things pleasant all
weekend, another trough will approach early next week.

The ridge should bring warming temperatures, with afternoon
readings topping out 10 to 15 degrees above normal (widespread
80s). The approach of another trough off the Pacific Northwest
coastline should begin to bring those temperatures back towards
normal, but will still be 3 to 7 degrees above (mid/upper 70s). ty

.SYNOPSIS...
Unseasonably warm temperatures will be across the Inland Northwest
through Wednesday as high pressure remains over the region. A weak
cold front will likely arrive on Thursday cooling temperatures
closer to normal. There will also be a chance for light mountain showers
Thursday into Friday morning with the passing front. Warm and dry
conditions will likely return for the weekend.

&&

.DISCUSSION...
Tonight and Tuesday: High pressure will be over the region for the
next 24 hours, although it will weaken slightly as a shortwave off
the Oregon coast pivots into it. A band of high level moisture
associated with the shortwave will sweep in from the south
overnight into Tuesday. The lift is weak especially as the
shortwave falls apart as it tracks into the upper ridge axis
position. Most of this moisture will be above 10k ft, so the
threat of any precipitation will be minor. But the best if any
chance will be across the Blue mountains Tuesday morning and then
into central ID panhandle by Tuesday afternoon. Otherwise
anticipate some areas of virga or isolated sprinkles with the
cloud band across southeast Washington and southern Idaho
panhandle. Meanwhile, low level temperatures will continue to
rise, about 2 to 4 degrees warmer on Tuesday. This would make
Tuesday the warmest day of the week. Winds will be light and
mostly east/northeast tonight into Tuesday morning, with southwest
winds creeping into the southern Columbia Basin and Palouse by
Tuesday afternoon. /rfox

Tuesday night through Thursday night...In the big picture a
splitting trough will move into the eastern Pacific by Tuesday
afternoon. By Wednesday afternoon the southern portion of the
split closes into a cut-off low with the best moisture and
dynamics staying well south of our area. What this will do is drag
a weakening trough through southern B.C. Wednesday night and
Thursday with best forcing staying in central B.C. There will be
some mid level moisture that will move into the area Wednesday
night and Thursday.

For Tuesday night the models keep showing a weak wave moving
out of northeast Oregon and just brushing our southeast zones.
I kept some very low end pops through the night, but am far from
impressed and thinking at this just may be some increasing mid-
level clouds.

Wednesday night through Thursday night...Slight chance to chance
pops over the Cascades Wednesday night...then the chance for
precipitation will track across the northern mountains and Idaho
Panhandle for Thursday and Thursday night. Precipitation as mainly
showers... however there appears to be enough mid level
instability to introduce a few lighting strikes for the far
northeast mountains and Idaho Panhandle zones late in the day
Thursday. Confidence is much better for some light shower than any
lightning. Any precipitation should be a tenth or less. A slight
up tick in the southwest winds can also be expected Thursday
afternoon with sustained winds around 10mph. /Tobin

Friday afternoon through Tuesday morning: The exiting mid-week
trough will be replaced by another ridge of high pressure for the
weekend. While the ridge looks to keep things pleasant all
weekend, another trough will approach early next week.

The ridge should bring warming temperatures, with afternoon
readings topping out 10 to 15 degrees above normal (widespread
80s). The approach of another trough off the Pacific Northwest
coastline should begin to bring those temperatures back towards
normal, but will still be 3 to 7 degrees above (mid/upper 70s). ty

&&

.AVIATION...
06Z TAFS: Increasing moisture from the south will result in some mid
to high level cloud cover above 12 kft agl. These clouds may
produce very light showers or sprinkles at KLWS and KPUW this
morning, but there is a better chance of just some virga. Skies
will remain hazy due to smoke from fires in central WA and OR.
This may result reduced vis down into MVFR category at KPUW. /SVH

.SYNOPSIS...
Afternoon temperatures will be in the 80s Monday through Wednesday
as warm high pressure brings summer like weather to the Inland
Northwest. A cold front will likely arrive on Thursday cooling
temperatures closer to average. There will also be a chance for
light rain showers Thursday into Friday morning with the passing
front. Warm and dry conditions will likely return for the weekend.

&&

.DISCUSSION...
High pressure will continue over the region today with
temperatures 3 to 5 degrees warmer than yesterday. A weak
shortwave is moving up the OR coast with high clouds pushing in
from the south overnight into Tuesday. /rfox.

&&

.AVIATION...
18Z TAFS: A warm and dry air mass will remain over eastern
Washington and north Idaho through 18z Wednesday with light winds.
High clouds will move in from the south as a weather disturbance
skirts the region. Some isolated showers are possible, but should
be mainly virga across the Blue mountains and central Id panhandle
mountains. /rfox.

.DISCUSSION...

Today and Tuesday: Light winds, warm temperatures and mainly clear
conditions are expected today. The Inland Northwest will be
squarely under the influence of a high pressure with the 500mb
ridge axis over central Washington. A shortwave trough currently
off the coast of northern California will shunt the ridge axis in
Montana by mid day Tuesday causing the 850mb thermal ridge to jump
east of the Cascades. Barring any unforeseen thick cloudiness,
Tuesday should be the warmest day of the week with mid to upper
80s common from central Washington into the Idaho Panhandle.
Widely scattered high based continue to be advertised by the NAM
and GFS Tuesday and Tuesday night over the Camas Prairie, Blue
Mountains and central Idaho Panhandle. Deep layer moisture will be
a limiting factor and cloud bases look to be above 10 thousand
feet. It is hard to get very excited about anything more than a
brief light shower looking at forecast soundings.

Wednesday and Thursday: The NAM, GFS and ECMWF have come into
better agreement that the warm upper ridge will break down
Wednesday into Thursday. A split flow pattern seems to be the
scenario the models have settled upon after several days of model
indecision. Precipitation chances have been trended downward. It
no longer appears that the Gulf of Alaska trough will phase with
the lower latitude low in the eastern Pacific. At this time, the
mountainous zones will have the best opportunity of measurable
rain Wednesday night into Thursday night. If this trend
continues, precipitation chances and amounts may need to be
decreased further. /GKoch

Friday through Monday: Another beautiful weekend is expected as a
ridge pattern will build into the region. A slight chance of rain
showers from the previous system is possible for the high mountain
areas on Friday. The rest of the region is expected to free of
rain. Warmer temperatures will begin to build back into the region
with highs reaching the mid 80s and lows around 50. /JDC

&&

.AVIATION...
12Z TAFS: A warm and dry air mass will remain over eastern
Washington and north Idaho through 12z Wednesday. High pressure
and weak pressure gradients region-wide will produce light winds.
A weak upper level disturbance off the California coast will bring
a bit of high cloudiness this afternoon and into the night with
cloud bases at or above 10 thousand feet. /GKoch
