.SYNOPSIS...
A deep low pressure system will bring showers and isolated
thunderstorms to most of the Inland Northwest through Wednesday
especially over northern Washington and the Idaho Panhandle.
Thursday morning will be cold with low temperatures down into the
lower to mid 30s for the mountain valley locations. The return of
high pressure Thursday through the weekend will bring several days
of dry weather, light winds, and warmer temperatures.

&&

.DISCUSSION...
As of 9 pm...radar indicated a potent closed low centered near
Mount Baker in the North Washington Cascades. Models are in good
agreement that this low will track east into the Northeast
Washington Mountains and North Idaho Panhandle tonight. As it does
so mid level cooling will be significant with 500mb temps falling
from -15 to -18C this evening to -19 to -21C overnight. This will
result in increased mid level instability resulting increasing
showers and isolated thunderstorms. The NAM shows elevated CAPE
values of 200-500 J/KG with the highest values near the Canadian
border. The track of the low will favor widespread showers over
the northern mountains...with numerous showers as far south as
Spokane/Coeur D`Alene. A dry slot coming around the low over
southern Washington should keep shower coverage isolated over the
Blue Mountains, Lewiston area, and Camas Prairie. Strong
downslope westerly flow off the Cascades will also keep coverage
isolated around Wenatchee and Moses Lake. With colder air moving
into the region tonight and 850mb winds of 25-35 kts gusty winds
are expected to continue.

On Wednesday as the low moves into Northwest Montana a band of
wrap around rain is expected over Northeast Washington into the
Idaho Panhandle. With good model agreement as well as upslope
winds into the higher terrain have increased POPS to near 100
percent for places like Sandpoint, Coeur D`Alene and Kellogg.
Cloud cover and showers look to persist through the day. The 00z
GFS and 12z ECMWF show 850mb temps only rebounding to
6-8C...suggesting a chilly day with mountain highs in the
40s...with 50s in the valleys. Temperatures have been cooled
slightly from Colville to Spokane east to the Idaho/Montana
border. JW

&&

.AVIATION...
00Z TAFS: A strong cold front will cross east of the Cascade Mtns
between 0-6z this evening. This front will produce gusty winds
from the west and will arrive at KEAT and KMWH between 00-02Z and
then push into the KGEG, KSFF, KCOE, KPUW and KLWS TAF sites
around 03-05Z. Blowing dust is possible around KMWH. Winds will
remain breezy through the overnight hours. Showers and
thunderstorms are expected across the northern mtns early this
evening into tonight with a few storms as far south as
KGEG/KSFF/KCOE. A band of wrap around moisture and upslope flow
into the Idaho Panhandle on Wednesday will produce steady rain and
MVFR conditions with some improvement likely in the afternoon.
Occasional MVFR conditions is possible at KGEG/KSFF Wednesday
morning depending on how far west the band of wrap around rain
extends. JW

451 PM PDT TUE SEP 2 2014

.SYNOPSIS...
Breezy winds are expected this evening with the passage of a cold
front. The front will also bring the potential for showers and
thunderstorms to the Idaho Panhandle and northern Washington
tonight into Wednesday. Thursday morning will be cold with low
temperatures down into the lower to mid 30s for the mountain
valley locations. The return of high pressure Thursday through the
weekend will bring several days of dry weather, light winds, and
warmer temperatures.

&&

.DISCUSSION...
Tonight: Showers, perhaps some thunder, and breezy conditions are
expected. A cold front and dynamic upper trough were pushing into
western Washington this afternoon. The cold front tracks east of
the Cascades early this evening, into the Panhandle around
midnight and exits into Montana by Wednesday AM. The upper trough,
however, will be slower to exit. Early this evening models keep
the main precipitation over the Cascades with the cold front and
along the Canadian border closer to the warm front. As the cold
front and upper trough start east of the Cascades, a surface
trough/trowal starts to become established across the northern
mountains. Precipitation is expected to increase in coverage
around the Okanogan, the mountains of northeast Washington and, by
late evening or early overnight, over the northern Panhandle.
Showers are also expected to develop over portions of the Basin
through central/southern Panhandle, especially from 8 PM and
beyond. However, being more removed from the upper support, these
should be more isolated to scattered in nature. This means not
every location will get wet, especially the further south and west
into the Basin and south toward the L-C valley. As the night
progresses into Wednesday morning the upper trough pivots east
toward the WA/ID border, with the trowal and moisture wrapping
just behind it. This will only serve to keep precipitation chances
high across north-central and northeast WA and chances going
across the upper Columbia Basin through Palouse and central
Panhandle. Smaller chances will be found toward the L-C Valley and
Camas Prairie.

As for the thunder prospects, modest CAPE is depicted this
evening around the Cascade crest and toward the northern
mountains. This abates through the evening and overnight, but weak
to moderate elevated instability lingers across northeast WA and
east-central WA and north ID overnight. So look for some thunder
chances across the Cascades through northern Panhandle, with the
main threat shifting toward northeast WA and north ID overnight.
Thunder coverage is not expected to be large, but storms may be
capable of heavy downpours and gusty winds.

As for the winds, WV imagery shows good darkening with the upper
trough/vorticity max and this suggests some good mixing with the
incoming front. So look for winds to really pick up as we go into
late afternoon and remain breezy to locally windy through this
evening. The strongest winds are expected closer to the Cascades,
especially near the ridge-tops. Lower elevations near the Cascades
could see sustained winds of 15 to 25 mph, with gusts around 30 to
40 mph. This includes the Wenatchee and Waterville Plateau area.
Nearby mountain-top winds, however, could gust between 50 to 60
mph. We will have to watch any convection that might fire in this
region for potentially strong winds reaching the lower elevations.
Speeds will abate overnight, but in a gradual way. The main area
that should miss out any strong winds will be toward the sheltered
valleys of northeast WA and north ID, with speeds in the 5 to 15 mph
range. /J. Cote`

Wednesday through Friday: The incoming upper trough will be
sitting over the forecast area as dawn breaks on Wednesday. Models
are in good agreement regarding the strength...track and speed of
this system. The trough cusp will feature areas of moderate to
strong vorticity dynamics with cooler air aloft decreasing
stability. Present for fuel will be around 3/4 inch precipitable
water which is very adequate for showers. All-in-all it appears
this system will bring a moderate amount of rain to parts of the
region...likely north and east of a line from Omak to
Pullman...during the day tomorrow. Character of precipitation will
probably be hit-and-miss showery over the northeast basin with
frequent or intermittent showers. The peripheral zones from the
east slopes of the cascades to the upper Columbia Basin and the
Palouse will experience more isolated and spotty showers. The deep
basin and cascades lee zones will probably only receive breezy
winds and clouds from this wave passage.

The upper trough will move out quickly on Wednesday night with a
general drying and clearing trend from west to east as the
backside ridge featuring dry northwest flow kicks in by Thursday
morning. A second weak wave will brush along the Canadian border
Thursday night but little beyond some enhanced cloud cover over
the northeast is expected at this time.

Temperatures particularly Thursday morning will have a nip of
Autumn to them...with overnight lows into the upper 30s possible
in the sheltered valleys north and east of the basin...along with
some patchy valley fog. Daytime highs on Wednesday will be well
below normal but begin a recovery Thursday as things dry out and
the ridge builds back. /Fugazzi

Friday night through Tuesday: A dome of high pressure will expand
over the Inland NW over the weekend bringing abundant sunshine...above
normal temperatures...and light winds. 850mb temperatures will
warm between 19-20C yielding temperatures in the 80`s to low 90`s.
The ridge of high pressure will weaken and shift west at the start
of the work week setting up persistent northwesterly flow into
Ern WA. The transition to NW flow will be marked by a shortwave
trof passage during the Sunday night/Monday time-frame. This
system will bring gusty winds...chance for showers...and return
to cooler...September like temperatures. Overall...deterministic
and ensemble member solutions are in good agreement and any
foreseeable changes will likely deal with timing and depth of the
Sunday night/Mon feature. GFS progs look like a carbon copy of the
next 24 hours while the ECMWF is a tad weaker. Both solutions
support the best chance for showers mainly along the Cascade Crest
and northern mountains of WA/ID and likelihood for breezy
conditions. 850mb temperatures cool to 15C Monday then 13C Tuesday
knocking temperatures back into the 70`s to lower 80`s. /sb

.AVIATION...
00Z TAFS: A strong cold front will cross east of the Cascade Mtns
between 0-6z this evening. This front will produce gusty winds
from the west and will arrive at KEAT and KMWH between 00-02Z and
then push into the KGEG, KSFF, KCOE, KPUW and KLWS TAF sites
around 03-05Z. Blowing dust is possible around KMWH. Winds will
remain breezy through the overnight hours. Showers and
thunderstorms are expected across the northern mtns early this
evening into tonight with a few storms as far south as
KGEG/KSFF/KCOE. A band of wrap around moisture and upslope flow
into the Idaho Panhandle on Wednesday will produce steady rain and
MVFR conditions with some improvement likely in the afternoon.
Occasional MVFR conditions is possible at KGEG/KSFF Wednesday
morning depending on how far west the band of wrap around rain

beyond. However, being more removed from the upper support, these
should be more isolated to scattered in nature. This means not
every location will get wet, especially the further south and west
into the Basin and south toward the L-C valley. As the night
progresses into Wednesday morning the upper trough pivots east
toward the WA/ID border, with the trowal and moisture wrapping
just behind it. This will only serve to keep precipitation chances
high across north-central and northeast WA and chances going
across the upper Columbia Basin through Palouse and central
Panhandle. Smaller chances will be found toward the L-C Valley and
Camas Prairie.

As for the thunder prospects, modest CAPE is depicted this
evening around the Cascade crest and toward the northern
mountains. This abates through the evening and overnight, but weak
to moderate elevated instability lingers across northeast WA and
east-central WA and north ID overnight. So look for some thunder
chances across the Cascades through northern Panhandle, with the
main threat shifting toward northeast WA and north ID overnight.
Thunder coverage is not expected to be large, but storms may be
capable of heavy downpours and gusty winds.

As for the winds, WV imagery shows good darkening with the upper
trough/vorticity max and this suggests some good mixing with the
incoming front. So look for winds to really pick up as we go into
late afternoon and remain breezy to locally windy through this
evening. The strongest winds are expected closer to the Cascades,
especially near the ridge-tops. Lower elevations near the Cascades
could see sustained winds of 15 to 25 mph, with gusts around 30 to
40 mph. This includes the Wenatchee and Waterville Plateau area.
Nearby mountain-top winds, however, could gust between 50 to 60
mph. We will have to watch any convection that might fire in this
region for potentially strong winds reaching the lower elevations.
Speeds will abate overnight, but in a gradual way. The main area
that should miss out any strong winds will be toward the sheltered
valleys of northeast WA and north ID, with speeds in the 5 to 15 mph
range. /J. Cote`

Wednesday through Friday: The incoming upper trough will be
sitting over the forecast area as dawn breaks on Wednesday. Models
are in good agreement regarding the strength...track and speed of
this system. The trough cusp will feature areas of moderate to
strong vorticity dynamics with cooler air aloft decreasing
stability. Present for fuel will be around 3/4 inch precipitable
water which is very adequate for showers. All-in-all it appears
this system will bring a moderate amount of rain to parts of the
region...likely north and east of a line from Omak to
Pullman...during the day tomorrow. Character of precipitation will
probably be hit-and-miss showery over the northeast basin with
frequent or intermittent showers. The peripheral zones from the
east slopes of the cascades to the upper Columbia Basin and the
Palouse will experience more isolated and spotty showers. The deep
basin and cascades lee zones will probably only receive breezy
winds and clouds from this wave passage.

The upper trough will move out quickly on Wednesday night with a
general drying and clearing trend from west to east as the
backside ridge featuring dry northwest flow kicks in by Thursday
morning. A second weak wave will brush along the Canadian border
Thursday night but little beyond some enhanced cloud cover over
the northeast is expected at this time.

Temperatures particularly Thursday morning will have a nip of
Autumn to them...with overnight lows into the upper 30s possible
in the sheltered valleys north and east of the basin...along with
some patchy valley fog. Daytime highs on Wednesday will be well
below normal but begin a recovery Thursday as things dry out and
the ridge builds back. /Fugazzi

Friday night through Tuesday: A dome of high pressure will expand
over the Inland NW over the weekend bringing abundant sunshine...above
normal temperatures...and light winds. 850mb temperatures will
warm between 19-20C yielding temperatures in the 80`s to low 90`s.
The ridge of high pressure will weaken and shift west at the start
of the work week setting up persistent northwesterly flow into
Ern WA. The transition to NW flow will be marked by a shortwave
trof passage during the Sunday night/Monday time-frame. This
system will bring gusty winds...chance for showers...and return
to cooler...September like temperatures. Overall...deterministic
and ensemble member solutions are in good agreement and any
foreseeable changes will likely deal with timing and depth of the
Sunday night/Mon feature. GFS progs look like a carbon copy of the
next 24 hours while the ECMWF is a tad weaker. Both solutions
support the best chance for showers mainly along the Cascade Crest
and northern mountains of WA/ID and likelihood for breezy
conditions. 850mb temperatures cool to 15C Monday then 13C Tuesday
knocking temperatures back into the 70`s to lower 80`s. /sb

.SYNOPSIS...
Breezy winds are expected this evening with the passage of a cold
front. The front will also bring the potential for showers and
thunderstorms to the Idaho Panhandle and northern Washington
tonight into Wednesday. Thursday morning will be cold with low
temperatures down into the lower to mid 30s for the mountain
valley locations. The return of high pressure Thursday through the
weekend will bring several days of dry weather, light winds, and
warmer temperatures.

&&

.DISCUSSION...
Tonight: Showers, perhaps some thunder, and breezy conditions are
expected. A cold front and dynamic upper trough were pushing into
western Washington this afternoon. The cold front tracks east of
the Cascades early this evening, into the Panhandle around
midnight and exits into Montana by Wednesday AM. The upper trough,
however, will be slower to exit. Early this evening models keep
the main precipitation over the Cascades with the cold front and
along the Canadian border closer to the warm front. As the cold
front and upper trough start east of the Cascades, a surface
trough/trowal starts to become established across the northern
mountains. Precipitation is expected to increase in coverage
around the Okanogan, the mountains of northeast Washington and, by
late evening or early overnight, over the northern Panhandle.
Showers are also expected to develop over portions of the Basin
through central/southern Panhandle, especially from 8 PM and
beyond. However, being more removed from the upper support, these
should be more isolated to scattered in nature. This means not
every location will get wet, especially the further south and west
into the Basin and south toward the L-C valley. As the night
progresses into Wednesday morning the upper trough pivots east
toward the WA/ID border, with the trowal and moisture wrapping
just behind it. This will only serve to keep precipitation chances
high across north-central and northeast WA and chances going
across the upper Columbia Basin through Palouse and central
Panhandle. Smaller chances will be found toward the L-C Valley and
Camas Prairie.

As for the thunder prospects, modest CAPE is depicted this
evening around the Cascade crest and toward the northern
mountains. This abates through the evening and overnight, but weak
to moderate elevated instability lingers across northeast WA and
east-central WA and north ID overnight. So look for some thunder

.SYNOPSIS...
Breezy winds are expected late this afternoon and early this
evening with the passage of a cold front. The front will also
bring the potential for showers and thunderstorms to the Idaho
Panhandle and northern Washington tonight into Wednesday. Thursday
morning will be cold with low temperatures down into the lower to
mid 30s for the mountain valley locations. The return of high
pressure Thursday through the weekend will bring several days of
dry weather, light winds, and warmer temperatures.


&&

.DISCUSSION...
Today and Tonight: Satellite imagery early this morning shows a
potent shortwave trough of lower pressure moving south along the
BC coastline. The trough axis is currently located over central BC
with water vapor imagery showing a well defined dry slot at 50N
135W in the Gulf of Alaska. This dry slot is a good approximation
of the back edge of the cold front. Models have this front progged
to cross east of the Cascade Mtns into the western basin after
5:00 PM this evening and then pushing into the Spokane Area/Palouse
by about 8:00 PM this evening. The mountains will see the best
chances for precip with the front; however, the basin up into the
Spokane Area, Coeur d`Alene Area down to the Palouse and L-C
Valley may only see some passing mid level clouds and possibly
some sprinkles or sporadic showers. There will be strong cold air
advection with the front, which will result in winds picking up
quite a bit along and behind the front. Strongest winds are
expected down the east slopes of the Cascade Mtns out over into
the western basin for the evening hours. Sustained wind speeds of
20-25 mph with gusts up to 40 mph will be possible. This is just
below our criteria for a Wind Advisory and a highlight is not
expected at this time. The windy conditions may also result in
some blowing dust across the Moses Lake Area, and could blow
across much of the basin. This may impact travel along I-90, with
the highest risk between George and Ritzville.

Behind the cold front we will see the upper level trough swing
through for the overnight hours. There is enough mid level
instability that widespread showers and even some thunderstorms
will be possible. Best areas for showers and thunderstorms will
be across the Okanogan highlands over to the Northern Panhandle.
The general progression of these showers and thunderstorms will
be to the east and southeast. This is expected to lead to at least
a chance for showers and thunderstorms across the upper basin to
the northern portions of the Palouse. Any thunderstorms that do
develop will be capable of drawing down stronger wind gusts aloft.

Wednesday and Wednesday night: The surface low will begin to track
away from the region across the Canadian border along the state of
Montana. With the low tracking away from the region, this will
allow surface gradients to weaken with a trend toward less windy
conditions across the region. There will be some moisture that
wraps around the low into the region, so a chance for showers and
thunderstorms will be possible into the afternoon and early
evening. Best chances for showers and thunderstorms will be in
extreme eastern WA and in the ID Panhandle. Temperature will be
much cooler on Wednesday. Much of extreme eastern WA and the ID
Panhandle will only warm up into the low to mid 60s with some
locations in the Panhandle having a hard time breaking 60 degrees.
Showers will dissipate overnight with skies clearing out. This
will result in temperatures plummeting overnight with the cold
pockets across the northern mountain and Panhandle valleys
dipping close to freezing. Frost will be possible, so any
sensitive vegetation should be protected for the potential of
frost or freeze damage. This will include locations such as
Republic and Deer Park. /SVH

Thursday through Saturday: A split flow pattern over the Pacific
Northwest will bring dry weather and light winds to the region
Thursday through Saturday. A light east to northeast pressure
gradient is expected to usher in dry surface dewpoints. The dry
air mass, light winds, and clear skies will allow for large
diurnal temperature swings. The northern valleys around Colville,
Deer Park, Priest Lake and Bonners Ferry will likely experience
low temperatures in the upper 30s and low 40s Friday and Saturday
morning with afternoon highs in the low 80s. Jacket weather in the
morning and shorts by the afternoon.

Sunday and Monday: The ECMWF and GFS are in pretty good agreement
that the next shortwave trough will arrive in the Sunday/Monday
time frame. The trough will come at us from the northwest which is
a relatively dry trajectory this time of year, so the forecast for
precipitation is pretty low at this time. If the medium range
models hold true, the cold front associated with this trough will
bring a period of breezy conditions Sunday or Monday and a cooling
trend early next week. /GKoch

.SYNOPSIS...
Breezy winds are expected late this afternoon and early this
evening with the passage of a cold front. The front will also
bring the potential for showers and thunderstorms to the Idaho
Panhandle and northern Washington tonight into Wednesday. Thursday
morning will be cold with low temperatures down into the lower to
mid 30s for the mountain valley locations. The return of high
pressure Thursday through the weekend will bring several days of
dry weather, light winds, and warmer temperatures.


&&

.DISCUSSION...
Today and Tonight: Satellite imagery early this morning shows a
potent shortwave trough of lower pressure moving south along the
BC coastline. The trough axis is currently located over central BC
with water vapor imagery showing a well defined dry slot at 50N
135W in the Gulf of Alaska. This dry slot is a good approximation
of the back edge of the cold front. Models have this front progged
to cross east of the Cascade Mtns into the western basin after
5:00 PM this evening and then pushing into the Spokane Area/Palouse
by about 8:00 PM this evening. The mountains will see the best
chances for precip with the front; however, the basin up into the
Spokane Area, Coeur d`Alene Area down to the Palouse and L-C
Valley may only see some passing mid level clouds and possibly
some sprinkles or sporadic showers. There will be strong cold air
advection with the front, which will result in winds picking up
quite a bit along and behind the front. Strongest winds are
expected down the east slopes of the Cascade Mtns out over into
the western basin for the evening hours. Sustained wind speeds of
20-25 mph with gusts up to 40 mph will be possible. This is just
below our criteria for a Wind Advisory and a highlight is not
expected at this time. The windy conditions may also result in
some blowing dust across the Moses Lake Area, and could blow
across much of the basin. This may impact travel along I-90, with
the highest risk between George and Ritzville.

Behind the cold front we will see the upper level trough swing
through for the overnight hours. There is enough mid level
instability that widespread showers and even some thunderstorms
will be possible. Best areas for showers and thunderstorms will
be across the Okanogan highlands over to the Northern Panhandle.
The general progression of these showers and thunderstorms will
be to the east and southeast. This is expected to lead to at least
a chance for showers and thunderstorms across the upper basin to
the northern portions of the Palouse. Any thunderstorms that do
develop will be capable of drawing down stronger wind gusts aloft.

Wednesday and Wednesday night: The surface low will begin to track
away from the region across the Canadian border along the state of
Montana. With the low tracking away from the region, this will
allow surface gradients to weaken with a trend toward less windy
conditions across the region. There will be some moisture that
wraps around the low into the region, so a chance for showers and
thunderstorms will be possible into the afternoon and early
evening. Best chances for showers and thunderstorms will be in
extreme eastern WA and in the ID Panhandle. Temperature will be
much cooler on Wednesday. Much of extreme eastern WA and the ID
Panhandle will only warm up into the low to mid 60s with some
locations in the Panhandle having a hard time breaking 60 degrees.
Showers will dissipate overnight with skies clearing out. This
will result in temperatures plummeting overnight with the cold
pockets across the northern mountain and Panhandle valleys
dipping close to freezing. Frost will be possible, so any
sensitive vegetation should be protected for the potential of
frost or freeze damage. This will include locations such as
Republic and Deer Park. /SVH

Thursday through Saturday: A split flow pattern over the Pacific
Northwest will bring dry weather and light winds to the region
Thursday through Saturday. A light east to northeast pressure
gradient is expected to usher in dry surface dewpoints. The dry
air mass, light winds, and clear skies will allow for large
diurnal temperature swings. The northern valleys around Colville,
Deer Park, Priest Lake and Bonners Ferry will likely experience
low temperatures in the upper 30s and low 40s Friday and Saturday
morning with afternoon highs in the low 80s. Jacket weather in the
morning and shorts by the afternoon.

Sunday and Monday: The ECMWF and GFS are in pretty good agreement
that the next shortwave trough will arrive in the Sunday/Monday
time frame. The trough will come at us from the northwest which is
a relatively dry trajectory this time of year, so the forecast for
precipitation is pretty low at this time. If the medium range
models hold true, the cold front associated with this trough will
bring a period of breezy conditions Sunday or Monday and a cooling
trend early next week. /GKoch

.AVIATION...
12Z TAFS: A strong cold front will cross east of the Cascade Mtns
late this afternoon through this evening. This front will produce
gusty winds from the west and will arrive at KEAT and KMWH between
23-02Z and then push into the KGEG, KSFF, KCOE, KPUW and KLWS
TAF sites around 03-04Z. Winds will remain breezy through the
overnight hours. Showers and thunderstorms are expected across the
northern mtns late this afternoon into tonight and then begin to
push into KGEG, KSFF and KCOE sometime late tonight into Wednesday
morning. /SVH

.SYNOPSIS...

The arrival of a cold front Tuesday afternoon and evening will
bring a return of gusty winds and cooler temperatures for Wednesday,
along with good threat of showers and thunderstorms. A warming and
drying trend is expected Thursday into next weekend.

&&

.DISCUSSION...

Tonight and Tuesday: Northwest flow will prevail across the Inland
Northwest for the next 24 hours, but a strong 100 kt jet in the
flow will push a fast moving cold front through the region late
Tuesday. For tonight, expect light winds, mild temperatures and
the cumulus to dissipate to mostly clear skies. For Tuesday, winds
will start off light as clouds increase from the west. The cold
front will sweep through the Cascades by Tuesday afternoon. This
will tighten pressure gradients and northwest winds will becoming
breezy. There is a chance of showers mainly near the Cascade crest
and in the far northern mountains into the evening hours. Increased
instability will be found along the front and could see a slight
chance of thunderstorms across the northern mountains as well.
/rfox.

Tues Nt through Wed Nt: The entire time frame will be focused on
a deep upper trough that will quickly move SE out of BC and into
Ern Wa and N Id while it fills/weaken/shears before moving into
Wrn Montana Wed. The core wx issues associated with the passage of
this trough and front will be gusty west winds, thunder/pcpn
amnts, and temperatures. Very gusty winds, especially near the
Cascades, will increase late Tues as cold advection and cross-
Cascade pressure gradients strengthen. The biggest challenge for
Wed will be deciding the areal coverage of showers and/or thunder
across NE Wa and the Id Panhandle. This will, of course, influence
temperatures with the increased cloud cover. As this wave fills,
it also develops a trowal structure Wed on the NE periphery of the
upper low that could significantly influence the amnt of pcpn that
Nrn Wa and N Id receives. As a result of this trowal feature,
banded pcpn could certainly be a problem across Ern Wa and N Id
Wed before the low moves east out of the area. Due to the
convective character of the wave, the deep cyclonic convergence
and trowal banding, significant pcpn amnts are possible. Storm
total rainfall amnts are fcst to be roughly three to six tenths
for the N Idaho Panhandle and NE Wa by Wed Nt. Cool high temps Wed
in the 60s where the heaviest rains fall looks increasing likely
as well. bz

Thursday to Monday: Mostly dry, warm conditions expected before
the next rain threat arrives early next week. A trough of low
pressure exits to the east and a ridge builds in through Saturday.
With regional PWATs dropping below 0.50 inches and broad-scale
subsidence, this will support dry and mostly clear conditions.
Mean 850mb temperatures warm 4 to 7 degrees by the end of the
week, supporting a warming trend that pushes highs from the mid-
70s Thursday to the lower 80s by Saturday. Saturday night through
Monday the next trough pushes in from the west-northwest. However
models continue to vary over the evolution, especially timing.
Look for some increase in cloud cover going into early next week.
A chance of showers returns to the Cascades Sunday and expands
toward northeast WA and north ID Monday. This may include areas as
far south Douglas county to Kootenai county. However there is too
much model disagreement to have high confidence. The incoming
trough is forecast to bring cooler temperatures by Monday.

06Z TAFS: A deep upper level trough will approach Tuesday
afternoon...then sending a strong cold front through North Central
Washington (including KEAT, KMWH) between 0-3z Wed...and then
across Eastern WA/N Idaho 3-6z. The timing of the strong cold
advection will coincide during better mixing potential in North
Central Washington with gusts 30-35 kts expected...with gusts
mostly between 20-30 kts elsewhere. Winds may pick up patchy
blowing dust around KMWH. The best chances for showers and

.SYNOPSIS...

The arrival of a cold front Tuesday afternoon and evening will
bring a return of gusty winds and cooler temperatures for Wednesday,
along with good threat of showers and thunderstorms. A warming and
drying trend is expected Thursday into next weekend.

&&

.DISCUSSION...

Tonight and Tuesday: Northwest flow will prevail across the Inland
Northwest for the next 24 hours, but a strong 100 kt jet in the
flow will push a fast moving cold front through the region late
Tuesday. For tonight, expect light winds, mild temperatures and
the cumulus to dissipate to mostly clear skies. For Tuesday, winds
will start off light as clouds increase from the west. The cold
front will sweep through the Cascades by Tuesday afternoon. This
will tighten pressure gradients and northwest winds will becoming
breezy. There is a chance of showers mainly near the Cascade crest
and in the far northern mountains into the evening hours. Increased
instability will be found along the front and could see a slight
chance of thunderstorms across the northern mountains as well.
/rfox.

Tues Nt through Wed Nt: The entire time frame will be focused on
a deep upper trough that will quickly move SE out of BC and into
Ern Wa and N Id while it fills/weaken/shears before moving into
Wrn Montana Wed. The core wx issues associated with the passage of
this trough and front will be gusty west winds, thunder/pcpn
amnts, and temperatures. Very gusty winds, especially near the
Cascades, will increase late Tues as cold advection and cross-
Cascade pressure gradients strengthen. The biggest challenge for
Wed will be deciding the areal coverage of showers and/or thunder
across NE Wa and the Id Panhandle. This will, of course, influence
temperatures with the increased cloud cover. As this wave fills,
it also develops a trowal structure Wed on the NE periphery of the
upper low that could significantly influence the amnt of pcpn that
Nrn Wa and N Id receives. As a result of this trowal feature,
banded pcpn could certainly be a problem across Ern Wa and N Id
Wed before the low moves east out of the area. Due to the
convective character of the wave, the deep cyclonic convergence
and trowal banding, significant pcpn amnts are possible. Storm
total rainfall amnts are fcst to be roughly three to six tenths
for the N Idaho Panhandle and NE Wa by Wed Nt. Cool high temps Wed
in the 60s where the heaviest rains fall looks increasing likely
as well. bz

Thursday to Monday: Mostly dry, warm conditions expected before
the next rain threat arrives early next week. A trough of low
pressure exits to the east and a ridge builds in through Saturday.
With regional PWATs dropping below 0.50 inches and broad-scale
subsidence, this will support dry and mostly clear conditions.
Mean 850mb temperatures warm 4 to 7 degrees by the end of the
week, supporting a warming trend that pushes highs from the mid-
70s Thursday to the lower 80s by the Saturday. Saturday night
through Monday the next trough pushes in from the west-northwest.
However models continue to vary over the evolution, especially
timing. Look for some increase in cloud cover going into early
next week. A chance of showers returns to the Cascades Sunday and
expands toward northeast WA and north ID Monday. This may include
areas as far south Douglas county to Kootenai county. However
there is too much model disagreement to have high confidence. The
incoming trough is forecast to bring cooler temperatures by
Monday. /J. Cote`

.SYNOPSIS...
Today will be the mildest and least breezy day of the holiday
weekend. Temperatures this afternoon will be in the 70s under
mostly sunny skies. The arrival of a cold front Tuesday afternoon
and evening will bring a return of breezy to windy conditions and
below average temperatures for Wednesday, along with some threat
of showers and thunderstorms. A warming and drying trend is
expected Thursday into next weekend.


&&

.DISCUSSION...
Today and Tonight: Fairly benign weather pattern as we transition
over onto the stable side of the upper level jet. A little bit of
fog is expected in the morning for the valleys in the Northeast
Mtns and in the Northern Panhandle. High temperatures will be a
few degrees warmer compared to yesterday, but will still be
slightly below normal for the beginning of September.

Tuesday and Tuesday night: A dynamic weather system will push into
the region out of BC. This system will drop down on the tail end
of the polar jet streak which will shift northeast across the
region today. Strong upper level dynamics will produce a
deepening surface low that will traverse the eastern edge of the
Great Divide. The cold front associated with this system will push
across the region during the late afternoon and evening hours.
Good cold air advection should allow stronger winds aloft to mix
down to the surface as the front pushes through even as we head
into the evening, which is typically when winds would start to
weaken. Winds up at 850 mbs will be up around 25-30 kts. This
will translate into sustained wind speeds of roughly 18-22 mph
with gusts up around 30-35 mph. Due to the southwesterly track to
this system, winds are expected to be quite windy down the
Okanogan Valley as well as through the Cascade gaps. Then these
winds will filter out over the basin through the evening with
frontal passage. The 06Z NAM has also come in a bit more unstable
and is more supportive of thunderstorms. Best chances for showers
and thunderstorms will be across the northern mtns, but chances
will extend as far south as the upper portions of the basin and
the northern portions of the Palouse. The track of storms will
generally be east to southeast with the northern mtns of WA seeing
convection first Tuesday afternoon and then transitioning into the
Panhandle into Tuesday night. Thunderstorms will provide the
potential for even stronger outflow winds that could enhance the
synoptic scale wind speeds mentioned previously with gusts closer
to 40-50 mph possible near convection. /SVH

Wednesday: The potential for showers and thunderstorms will be the
primary weather concern for Wednesday as a positively tilted 500mb
trough lingers over north Idaho. It appears that the trough will
be undergoing a split on Wednesday with the most substantial
synoptic scale forcing shearing into southern Alberta and
Saskatchewan. The 0z ECMWF and 6z NAM dig the 500mb cold pool
into north Idaho and eastern Washington a bit more aggressively
than the GFS. The Weather Prediction Center favors the deeper
solution over north Idaho, so a good chance of showers and
thunderstorms has been retained for places like Sandpoint,
Kellogg, Priest lake and Northport. Elsewhere, limited deep layer
instability and marginal mid-level lapse rates suggest low chances
for convection. Wednesday should be the coolest day region-wide
under the upper level cold pool with afternoon highs in the mid
60s to mid 70s.

Thursday and Friday: A split flow pattern is expected to develop
over the Pacific Northwest Thursday and Friday. A weak upper low
will likely develop near northern California as the southern
polar branch sags southward. The northern branch will be much more
vigorous and cut through the northern/central Canadian Prairies.
Washington and Idaho will be squarely between the two branches of
the jet, and left mainly dry. Look for a gradual warming trend
over the second half of the week into the weekend. /GKoch

Saturday through Monday night: A warming and drying trend will
continue into the weekend over the Inland Northwest, with above
normal temperatures expected. However, yet another trough will
bring cooler temperatures and increased chances for precipitation
early next week.

Weak ridging will nose its way over the region Saturday and
remain there on Sunday before another trough traverses the area
Sunday night into early next week. The ridging will suppress any
chances at precipitation, while also allowing temperatures to rise
into the upper 70s (east) to mid/upper 80s west.

Sunday night or Monday, a trough will beat down the ridge, and
move over the region, cooling temperatures back to seasonal
normals and increasing precipitation chances. Right now, the
precipitation chances look to be confined to the higher terrain of
the Cascades and the mountains of northeast Washington and the
Idaho Panhandle. ty

deepening surface low that will traverse the eastern edge of the
Great Divide. The cold front associated with this system will push
across the region during the late afternoon and evening hours.
Good cold air advection should allow stronger winds aloft to mix
down to the surface as the front pushes through even as we head
into the evening, which is typically when winds would start to
weaken. Winds up at 850 mbs will be up around 25-30 kts. This
will translate into sustained wind speeds of roughly 18-22 mph
with gusts up around 30-35 mph. Due to the southwesterly track to
this system, winds are expected to be quite windy down the
Okanogan Valley as well as through the Cascade gaps. Then these
winds will filter out over the basin through the evening with
frontal passage. The 06Z NAM has also come in a bit more unstable
and is more supportive of thunderstorms. Best chances for showers
and thunderstorms will be across the northern mtns, but chances
will extend as far south as the upper portions of the basin and
the northern portions of the Palouse. The track of storms will
generally be east to southeast with the northern mtns of WA seeing
convection first Tuesday afternoon and then transitioning into the
Panhandle into Tuesday night. Thunderstorms will provide the
potential for even stronger outflow winds that could enhance the
synoptic scale wind speeds mentioned previously with gusts closer
to 40-50 mph possible near convection. /SVH

Wednesday: The potential for showers and thunderstorms will be the
primary weather concern for Wednesday as a positively tilted 500mb
trough lingers over north Idaho. It appears that the trough will
be undergoing a split on Wednesday with the most substantial
synoptic scale forcing shearing into southern Alberta and
Saskatchewan. The 0z ECMWF and 6z NAM dig the 500mb cold pool
into north Idaho and eastern Washington a bit more aggressively
than the GFS. The Weather Prediction Center favors the deeper
solution over north Idaho, so a good chance of showers and
thunderstorms has been retained for places like Sandpoint,
Kellogg, Priest lake and Northport. Elsewhere, limited deep layer
instability and marginal mid-level lapse rates suggest low chances
for convection. Wednesday should be the coolest day region-wide
under the upper level cold pool with afternoon highs in the mid
60s to mid 70s.

Thursday and Friday: A split flow pattern is expected to develop
over the Pacific Northwest Thursday and Friday. A weak upper low
will likely develop near northern California as the southern
polar branch sags southward. The northern branch will be much more
vigorous and cut through the northern/central Canadian Prairies.
Washington and Idaho will be squarely between the two branches of
the jet, and left mainly dry. Look for a gradual warming trend
over the second half of the week into the weekend. /GKoch

Saturday through Monday night: A warming and drying trend will
continue into the weekend over the Inland Northwest, with above
normal temperatures expected. However, yet another trough will
bring cooler temperatures and increased chances for precipitation
early next week.

Weak ridging will nose its way over the region Saturday and
remain there on Sunday before another trough traverses the area
Sunday night into early next week. The ridging will suppress any
chances at precipitation, while also allowing temperatures to rise
into the upper 70s (east) to mid/upper 80s west.

Sunday night or Monday, a trough will beat down the ridge, and
move over the region, cooling temperatures back to seasonal
normals and increasing precipitation chances. Right now, the
precipitation chances look to be confined to the higher terrain of
the Cascades and the mountains of northeast Washington and the
Idaho Panhandle. ty

.SYNOPSIS...
Today will be the mildest and least breezy day of the holiday
weekend. Temperatures this afternoon will be in the 70s under
mostly sunny skies. The arrival of a cold front Tuesday afternoon
and evening will bring a return of breezy to windy conditions and
below average temperatures for Wednesday, along with some threat
of showers and thunderstorms. A warming and drying trend is
expected Thursday into next weekend.


&&

.DISCUSSION...
Today and Tonight: Fairly benign weather pattern as we transition
over onto the stable side of the upper level jet. A little bit of
fog is expected in the morning for the valleys in the Northeast
Mtns and in the Northern Panhandle. High temperatures will be a
few degrees warmer compared to yesterday, but will still be
slightly below normal for the beginning of September.

Tuesday and Tuesday night: A dynamic weather system will push into
the region out of BC. This system will drop down on the tail end
of the polar jet streak which will shift northeast across the
region today. Strong upper level dynamics will produce a
deepening surface low that will traverse the eastern edge of the
Great Divide. The cold front associated with this system will push
across the region during the late afternoon and evening hours.

.SYNOPSIS...
Sunday will be cooler than average, with scattered showers over
Northeast Washington and the Idaho Panhandle, with breezy
conditions over the Columbia Basin. Look for winds to be a bit
lighter on Labor Day, with mostly sunny skies. The arrival of a
cold front Tuesday afternoon will bring a return of breezy
conditions and below average temperatures for Wednesday, along
with some threat of showers and thunderstorms. A warming and
drying trend is expected Thursday into next weekend.

&&

.DISCUSSION...
Tonight and Labor Day: The scattered showers tracking across NE
Washington and N Idaho this afternoon will start to diminish after
sunset and come to an end once we lose the upper forcing. The
upper jet will slide north, placing us on the stable side. Mid
level heights will also start to rise as the shortwave trough
moves east. Once the showers end, the northeast valleys could see
some patchy fog develop where low level moisture is plentiful, and
if there is some clearing overnight. Upslope flow into the Spokane
and Coeur d`Alene areas will likely allow some low stratus to
develop. This area saw low clouds Sunday morning and conditions
will be similar for Monday morning. On Labor Day, rising heights
and less cloud cover will bring drier conditions and will allow
daytime temperatures to warm a bit over Sunday`s readings with
valleys in the 70s to low 80s. /Kelch

Mon Nt through Wed: The entire time frame will be focused on a
deep upper trough that will quickly move SE out of BC and into Ern
Wa and N Id while it fills. The wx issues will be gusty west
winds, thunder/pcpn amnts, and temperatures. Very gusty winds,
especially near the Cascades, will follow a dry frontal passage
and rather strong cold advection and cross-Cascade pressure
gradients Tues. It`s not until Tues Nt that the upper trough is
directly over the region, followed by shearing/weakening as the
Nrn half of the trough moves into Wrn Montana. The biggest
challenge for Wed will be deciding the areal coverage of showers
and/or thunder across NE Wa and the Id Panhandle. This will, of
course, influence temperatures with the increased cloud cover. As
this wave fills, it also develops a trowal structure Tues Nt and
Wed on the NE periphery of the upper low that could significantly
influence the amnt of pcpn that Nrn Wa and N Id receives. As a
result of this trowal feature, banded pcpn could certainly be a
problem across Ern Wa and N Id Wed before the low moves east out
of the area. We did not make huge changes to the fcst due to the
convective character of the wave, and kept very gusty winds in
place near the Cascades. Cool temps across NE Wa and N Idaho and
cloudy skies with isolated thunder Wed in NE Wa and N Idaho seems
likely as well.bz

Wednesday night through Sunday: The threat of showers ends early
this period, followed by a warming and drying trend. A trough of
low pressure migrates out of the region Wednesday night into
Thursday morning. Lingering instability around the eastern
mountains will work with the trough to keep a threat of showers
alive through Thursday morning over the NE WA and ID Panhandle
mountains. Overall look for decreasing cloud cover across the
region and drier conditions Wednesday night and Thursday. From
Friday to Sunday model consistency is fair to poor. Yet there
seems to be a trend toward shortwave ridging over the region, with
a trough of low pressure south. I`d almost call that set-up a "Rex
Block" if it was stronger or more persistent. This is accompanied
by decreasing atmosphere moisture and less convective instability.
Models show the tail of a couple mid-level shortwaves crossing the
region, or just skimming the Canadian border, between Thursday and
Friday night. This will result in passing middle to high clouds.
Otherwise mostly clear and dry conditions are expected through
Sunday. We will be watching Sunday night (into early next week)
for the next potential trough and precipitation-maker. /J. Cote`

00Z TAFS: Flat-moderate cumulus over Eastern WA/N Idaho with bases

tonight around KSFF/KCOE however dew points have fallen quite a
bit this afternoon and NAM model shows a drier boundary layer

cloudy skies with isolated thunder Wed in NE Wa and N Idaho seems
likely as well.bz

Wednesday night through Sunday: The threat of showers ends early
this period, followed by a warming and drying trend. A trough of
low pressure migrates out of the region Wednesday night into
Thursday morning. Lingering instability around the eastern
mountains will work with the trough to keep a threat of showers
alive through Thursday morning over the NE WA and ID Panhandle
mountains. Overall look for decreasing cloud cover across the
region and drier conditions Wednesday night and Thursday. From
Friday to Sunday model consistency is fair to poor. Yet there
seems to be a trend toward shortwave ridging over the region, with
a trough of low pressure south. I`d almost call that set-up a "Rex
Block" if it was stronger or more persistent. This is accompanied
by decreasing atmosphere moisture and less convective instability.
Models show the tail of a couple mid-level shortwaves crossing the
region, or just skimming the Canadian border, between Thursday and
Friday night. This will result in passing middle to high clouds.
Otherwise mostly clear and dry conditions are expected through
Sunday. We will be watching Sunday night (into early next week)
for the next potential trough and precipitation-maker. /J. Cote`

00Z TAFS: Flat-moderate cumulus over Eastern WA/N Idaho with bases
8k-12k feet MSL will gradually dissipate tonight with the loss of
daytime heating. Isolated showers will continue through 03z around
Bonners Ferry.  There has been a concern for stratus to redevelop
tonight around KSFF/KCOE however dew points have fallen quite a
bit this afternoon and NAM model shows a drier boundary layer
tonight and thus a MVFR stratus deck does not appear likely for
any of the TAF sites. Up near the Canadian border around
Sandpoint and Bonners Ferry a bit more low level moisture exists
where a MVFR stratus deck is possible Monday morning.  JW

.SYNOPSIS...
Sunday will be cooler than average, with scattered showers over
Northeast Washington and the Idaho Panhandle, with breezy
conditions over the Columbia Basin. Look for winds to be a bit
lighter on Labor Day, with mostly sunny skies. The arrival of a
cold front Tuesday afternoon will bring a return of breezy
conditions and below average temperatures for Wednesday, along
with some threat of showers and thunderstorms. A warming and
drying trend is expected Thursday into next weekend.

&&

.DISCUSSION...
Tonight and Labor Day: The scattered showers tracking across NE
Washington and N Idaho this afternoon will start to diminish after
sunset and come to an end once we lose the upper forcing. The
upper jet will slide north, placing us on the stable side. Mid
level heights will also start to rise as the shortwave trough
moves east. Once the showers end, the northeast valleys could see
some patchy fog develop where low level moisture is plentiful, and
if there is some clearing overnight. Upslope flow into the Spokane
and Coeur d`Alene areas will likely allow some low stratus to
develop. This area saw low clouds Sunday morning and conditions
will be similar for Monday morning. On Labor Day, rising heights
and less cloud cover will bring drier conditions and will allow
daytime temperatures to warm a bit over Sunday`s readings with
valleys in the 70s to low 80s. /Kelch

Mon Nt through Wed: The entire time frame will be focused on a
deep upper trough that will quickly move SE out of BC and into Ern
Wa and N Id while it fills. The wx issues will be gusty west
winds, thunder/pcpn amnts, and temperatures. Very gusty winds,
especially near the Cascades, will follow a dry frontal passage
and rather strong cold advection and cross-Cascade pressure
gradients Tues. It`s not until Tues Nt that the upper trough is
directly over the region, followed by shearing/weakening as the
Nrn half of the trough moves into Wrn Montana. The biggest
challenge for Wed will be deciding the areal coverage of showers
and/or thunder across NE Wa and the Id Panhandle. This will, of
course, influence temperatures with the increased cloud cover. As
this wave fills, it also develops a trowal structure Tues Nt and
Wed on the NE periphery of the upper low that could significantly
influence the amnt of pcpn that Nrn Wa and N Id receives. As a
result of this trowal feature, banded pcpn could certainly be a
problem across Ern Wa and N Id Wed before the low moves east out
of the area. We did not make huge changes to the fcst due to the
convective character of the wave, and kept very gusty winds in
place near the Cascades. Cool temps across NE Wa and N Idaho and
cloudy skies with isolated thunder Wed in NE Wa and N Idaho seems
likely as well.bz

.DISCUSSION...
A shortwave trough sliding across the region is bringing scattered
showers and a couple of lightning strikes to Northeast WA and the
Idaho panhandle this morning. The northeast zones are in the
favored area where the cold pool aloft is increasing instability
on the unstable side of the upper jet. Westerly flow is also
adding an upslope component to enhance lift into the eastern
mountains. The morning update is to add isolated to scattered
showers farther west into the northern portions of the
Spokane-C`dA areas and into southern Stevens County. Radar imagery
is showing persistent little showers popping up over the Deer Park
area and back building as the initial showers dissipate. There is
a low probability of a few lightning strikes over extreme NE WA
and the northern panhandle of ID this afternoon. Sky cover and
temps have also been adjusted accordingly. Scattered showers will
persist across the eastern zones today, then diminish tonight as
the jet slides north, placing us on the stable side of said jet.
Not a washout today for those with outdoor plans, but keep an eye
to the sky as a precaution. /Kelch

.SYNOPSIS...
Today will be cooler than average with scattered showers over the
mountains and breezy conditions over the Columbia Basin. Look for
winds to be a bit lighter on Labor Day with mostly sunny skies
region-wide. The arrival of a cold front Tuesday afternoon will
bring a return of breezy conditions to eastern Washington and
below average temperatures for Wednesday. A gradual warming and
drying trend is expected Thursday into next weekend.

&&

.DISCUSSION...

Today through Monday night: The region remains under the western
portion of a broad area of an upper level trough of lower
pressure. We also continue to be on the unstable side of the
upper level jet. Moist westerly flow combined with a little bit of
instability is responsible for much of the shower activity across
the ID Panhandle through the overnight hours. We have also seen
just enough instability for some lightning strikes under the
stronger cells in the Central Panhandle Mountains. The NAM model
is doing a pretty good job capturing the deeper instability where
these stronger cells are popping up. Sounding profiles suggest
that this instability will become increasingly more capped through
the morning hours, so these thunderstorms are not expected to
remain over the area for long. Showers will continue across the
Panhandle into the afternoon hours, and will then decrease
overnight has temperatures aloft warm and mid level lapse rates
continue to stabilize. Winds will once again become breezy this
afternoon similar to yesterday. All areas are expected to be dry
on Labor Day as we continue to transition over onto the stable
side of the upper level jet. Temperatures will also begin to warm
up a few degrees with highs in the 70s for most locations on Labor
Day. /SVH

Tuesday: There is good agreement between the NAM, GFS and ECMWF
that a shortwave pressure trough will drop down the British
Columbia coast on Tuesday. Current satellite imagery shows this
trough near the Aleutian Chain and by Tuesday evening this feature
should be near the Olympic Peninsula. At this time, the most
noticeable weather for eastern Washington on Tuesday looks to be
increasingly breezy conditions during the afternoon and evening
hours as the surface front crosses the Cascades. Gap winds through
the Wenatchee River valley, Lake Chelan area, and the Methow
Valley Tuesday evening will have a good chance of producing gusts
in the 25 to 35 mph range. For the Columbia Basin, Palouse and
West Plains, the pressure gradient appears to tighten during the
evening hours as the sun sets. The formation of the typical
evening inversion may inhibit mechanical mixing to the surface,
but sustained winds of 10-15mph with gusts of 20 mph or more may
still be possible given the degree of low level cold advection and
momentum aloft (25kts at 850mb).

Wednesday: The upper level trough is expected to graze northeast
Washington and far north Idaho on Wednesday bringing the best
chance for showers and thunderstorms to the mountains along the
Canadian border. Deep layer instability will be limited, so strong
storms are not anticipated. The biggest change to the Wednesday
forecast was cooling afternoon temperatures into the upper 60s to
mid 70s for the majority of the forecast area.

Thursday: An elongated 500mb trough will linger over Washington
and north Idaho on Thursday, but the majority of the mid-level
moisture and instability will shear eastward. A 20 percent chance
for light showers has been retained for the mountains of the Idaho
Panhandle and extreme northeast Washington. The remainder of the
Inland Northwest will undergo a push of light northeast winds
bringing dry dewpoints. Afternoon temperatures should rebound a
bit after Wednesday`s cool readings, but highs will remain below
average Thursday. /GKoch

Friday through Sunday night: Fairly benign weather will dominate
over the Inland Northwest during this time frame, with warming
temperatures (to just above normal for the weekend) and dry
weather expected. The mid- week trough will be exiting to the
east, and most of the extended models close off the southern
portion of the trough over northern California. Any weather
disturbance during the Friday and Saturday time frame will be
moving more into British Columbia, which should keep much of any
precipitation chances slim over the region. However, with the low
pressure sitting off the northern California coastline, some
moisture may get worked north into the Idaho Panhandle, and maybe
as far west as far SE Washington.

A stronger trough will begin affecting eastern Washington and the
Idaho Panhandle late in the weekend or early next week. The far
extended models disagree on timing with this feature, but this
should bring another period of cooling temperatures, increased
winds, and slight chances for precipitation. ty

12Z TAFS: Low stratus between the Spokane/Coeur d`Alene corridor
may produce some MVFR cigs early this morning. This low level
moisture will likely lift into a cumulus field by the late morning
hours with cigs rising into VFR category. Showers are expected to
remain mainly over the mountains in the ID Panhandle today and
then dissipate tonight. Winds will be a little breezy through the
afternoon with gusts up to around 20-25 mph at times. /SVH

on Labor Day as we continue to transition over onto the stable
side of the upper level jet. Temperatures will also begin to warm
up a few degrees with highs in the 70s for most locations on Labor
Day. /SVH

Tuesday: There is good agreement between the NAM, GFS and ECMWF
that a shortwave pressure trough will drop down the British
Columbia coast on Tuesday. Current satellite imagery shows this
trough near the Aleutian Chain and by Tuesday evening this feature
should be near the Olympic Peninsula. At this time, the most
noticeable weather for eastern Washington on Tuesday looks to be
increasingly breezy conditions during the afternoon and evening
hours as the surface front crosses the Cascades. Gap winds through
the Wenatchee River valley, Lake Chelan area, and the Methow
Valley Tuesday evening will have a good chance of producing gusts
in the 25 to 35 mph range. For the Columbia Basin, Palouse and
West Plains, the pressure gradient appears to tighten during the
evening hours as the sun sets. The formation of the typical
evening inversion may inhibit mechanical mixing to the surface,
but sustained winds of 10-15mph with gusts of 20 mph or more may
still be possible given the degree of low level cold advection and
momentum aloft (25kts at 850mb).

Wednesday: The upper level trough is expected to graze northeast
Washington and far north Idaho on Wednesday bringing the best
chance for showers and thunderstorms to the mountains along the
Canadian border. Deep layer instability will be limited, so strong
storms are not anticipated. The biggest change to the Wednesday
forecast was cooling afternoon temperatures into the upper 60s to
mid 70s for the majority of the forecast area.

Thursday: An elongated 500mb trough will linger over Washington
and north Idaho on Thursday, but the majority of the mid-level
moisture and instability will shear eastward. A 20 percent chance
for light showers has been retained for the mountains of the Idaho
Panhandle and extreme northeast Washington. The remainder of the
Inland Northwest will undergo a push of light northeast winds
bringing dry dewpoints. Afternoon temperatures should rebound a
bit after Wednesday`s cool readings, but highs will remain below
average Thursday. /GKoch

Friday through Sunday night: Fairly benign weather will dominate
over the Inland Northwest during this time frame, with warming
temperatures (to just above normal for the weekend) and dry
weather expected. The mid- week trough will be exiting to the
east, and most of the extended models close off the southern
portion of the trough over northern California. Any weather
disturbance during the Friday and Saturday time frame will be
moving more into British Columbia, which should keep much of any
precipitation chances slim over the region. However, with the low
pressure sitting off the northern California coastline, some
moisture may get worked north into the Idaho Panhandle, and maybe
as far west as far SE Washington.

A stronger trough will begin affecting eastern Washington and the
Idaho Panhandle late in the weekend or early next week. The far
extended models disagree on timing with this feature, but this
should bring another period of cooling temperatures, increased
winds, and slight chances for precipitation. ty

Area Forecast Discussion

257 AM PDT SUN AUG 31 2014

.SYNOPSIS...
Today will be cooler than average with scattered showers over the
mountains and breezy conditions over the Columbia Basin. Look for
winds to be a bit lighter on Labor Day with mostly sunny skies
region-wide. The arrival of a cold front Tuesday afternoon will
bring a return of breezy conditions to eastern Washington and
below average temperatures for Wednesday. A gradual warming and
drying trend is expected Thursday into next weekend.

&&

.DISCUSSION...

Today through Monday night: The region remains under the western
portion of a broad area of an upper level trough of lower
pressure. We also continue to be on the unstable side of the
upper level jet. Moist westerly flow combined with a little bit of
instability is responsible for much of the shower activity across
the ID Panhandle through the overnight hours. We have also seen
just enough instability for some lightning strikes under the
stronger cells in the Central Panhandle Mountains. The NAM model
is doing a pretty good job capturing the deeper instability where
these stronger cells are popping up. Sounding profiles suggest
that this instability will become increasingly more capped through
the morning hours, so these thunderstorms are not expected to
remain over the area for long. Showers will continue across the
Panhandle into the afternoon hours, and will then decrease
overnight has temperatures aloft warm and mid level lapse rates
continue to stabilize. Winds will once again become breezy this
afternoon similar to yesterday. All areas are expected to be dry
on Labor Day as we continue to transition over onto the stable
side of the upper level jet. Temperatures will also begin to warm
up a few degrees with highs in the 70s for most locations on Labor
Day. /SVH

.SYNOPSIS...
The Labor Day weekend will be cooler than normal, with locally
breezy conditions. Aside from isolated showers, the majority of
the Inland Northwest will remain dry. A continued cool pattern is
expected through the middle of next week, with the best chance for
showers and thunderstorms Wednesday. Relatively warmer, drier
weather is forecast late next week.


&&

.DISCUSSION...
Update: The upper level disturbance that brought a cluster of
showers and thunderstorms to northeast Oregon is moving away from
the area this evening. An outflow boundary was generated from this
convection which as it moved north towards the palouse generated
some additional cells with a few lightning strikes noted between 6
pm and 8 pm north and northeast of Pullman. These cells have
weakened in the past half hour with the loss of daytime heating.
For the remainder of tonight the northwest flow and moistening low
level air mass will produce upslope showers into the Central
Panhandle Mountains. Elevated mid level instability will also be
present in this area especially this evening. Meanwhile a few
showers associated with an upper trough in British Columbia will
clip far northern Washington and Idaho with a bit of mid level
instability aiding in these showers persisting into the overnight
hours. Some other minor forecast updates have been made to low
temperatures and winds based on latest trends. JW
