Area Forecast Discussion
National Weather Service Spokane WA
428 AM PDT MON AUG 31 2015

.SYNOPSIS...
A cool, occasionally breezy and showery weather pattern is
expected through the week with the Inland northwest laying close
to the polar storm track.

&&

.DISCUSSION...

Today through Tuesday...Longwave trof lingers over the area
through this forecast interval and beyond which allows for
shortwaves running through it to maintain their forcing and
moisture feeds thus pops through most of this interval run quite
high along the Cascade crest and near the Canadian border
depicting such activity. The 0-6km AGL average winds from the
models I`ve looked at this morning suggest convection should move
to the northeast at 30 to 35 mph through this time period which is
fast enough to keep from having a high rainfall rate cell sit in
one place for too long so for locations east of the Cascade crest
I still see minimal signs for anything beyond very isolated and
localized debris flow problems on burn scars if they occur at all.
Given the trof solution with some convection and associated cloud
cover forecast daytime high temperatures should run on the cool
side of normal while overnight lows will stay closer to normal but
may lie slightly on the cool side as well. This pattern continues
to favor winds blowing out from the southwest but with slightly
less intensity as they did yesterday (Sunday). Of additional note
is a mention of patchy valley and lowland fog in some locations
due to Sundays abundant rainfall in some spots, this is in
addition to the persistent mention of smoke from area fires.
/Pelatti

Wednesday through Thursday...Model agreement is good and
consistent over multiple runs in depicting an unsettled and
continued troffy pattern over the region. High confidence exists
for a cooler than normal...showery and breezy regime over the
forecast area. Wednesday will feature another cold front passage
with elevated breezy to windy conditions with gust potential in
the 30 mph range over much of the exposed terrain of the area.
Not as bad as last Saturday but none-the-less probably the
breeziest day of the extended period. Showers with this front may
bring another tenth or two of an inch of rain to many locations
with a small chance of thunderstorms across the northern
mountains.

Friday through Sunday...Models consensus diverges somewhat
with the latest EC dropping a strong cold closed low right into
the forecast area with a possible stratiform rain bearing
deformation region wrapping around it...which would argue for a
significant amount of much needed rain for much of the area. The
GFS also shows a trough passage but less wet and aggressive
suggesting a decent chance of showers on Friday but a general
drying trend saturday and Sunday. So forecast confidence is
reasonably high for another cool and unsettled day Friday with the
potential for garden variety thunderstorms over much of the region
but confidence deteriorates sharply for the later periods of the
forecast. /Fugazzi

&&

.AVIATION...
12Z TAFS: Smoke from regional fires will impact KLWS and KPUW TAFS the
most from time to time given the prevailing southwest flow.
Additionally some morning fog and stratus will form in valleys to
the north and near the Spokane and Coeur d`Alene area
TAFS. Southwest flow is likely to become gusty again in the
afternoon and evening hours...otherwise VFR conditions should
prevail. /Pelatti

1030 PM PDT SUN AUG 30 2015

.SYNOPSIS...
Showers, thunderstorms and breezy winds will diminish through the
evening hours as a vigorous upper level weather system exits the
region. A cool, occasionally breezy and showery weather pattern is
expected much of next week.


&&

.DISCUSSION...
Showers and isolated thunderstorms have ended over eastern WA and
north ID this evening as the upper trough and associated cold pool
aloft have moved off into Montana. The exception is the area
right along the Cascade crest where moist upslope flow will keep
precipitation going tonight. Some minor changes were made to the
current forecast package but the main purpose of this update is to
remove the thunderstorm wording from the zones. The next system
upstream evident on satellite water vapor imagery this evening
will bring cool conditions and a chance of more showers to the
northern tier Monday. /Kelch

.SYNOPSIS...
Showers, thunderstorms and breezy winds will diminish through the
evening hours as a vigorous upper level weather system exits the
region. A cool, occasionally breezy and showery weather pattern is
expected much of next week.


&&

.DISCUSSION...
Showers and isolated thunderstorms have ended over eastern WA and
north ID this evening as the upper trough and associated cold pool
aloft have moved off into Montana. The exception is the area
right along the Cascade crest where moist upslope flow will keep
precipitation going tonight. Some minor changes were made to the
current forecast package but the main purpose of this update is to
remove the thunderstorm wording from the zones. The next system
upstream evident on satellite water vapor imagery this evening
will bring cool conditions and a chance of more showers to the
northern tier Monday. /Kelch

&&

.AVIATION...
06Z TAFS: Showers have ended across eastern WA and north ID this
evening but precipitation will continue for the Cascade crest
tonight. Low level moisture from recent rainfall and light
upslope flow may allow MVFR ceilings in low stratus to form
between around 11Z to 15Z...affecting KGEG/KSFF/KCOE but
confidence is only fair. The next weather system will bring
showers along the International border Monday but the TAF sites
should remain dry. Winds may become gusty during the afternoon
hours but will diminish again after sunset. /EK

.SYNOPSIS...
Showers, thunderstorms and breezy winds will diminish through the
evening hours as a vigorous upper level weather system exits the
region. A cool, occasionally breezy and showery weather pattern is
expected much of next week.

&&

.DISCUSSION...

Tonight: Isolated to scattered showers will continue into the
early evening as the upper level trough of low pressure crosses
the region. Much of this shower activity will be located across
the eastern half of the forecast area. Isolated thunderstorms will
also be possible through the early evening. I don`t think we will
be able to generate enough instability for thunderstorms to be a
big threat. Strongest storms are expected to be across the
northern mountains with small hail, heavy downpours and gusty
winds to 40 mph possible.

Monday through Tuesday: Another shortwave trough will swing by the
region on Monday and Monday night. This system will mostly be a
glancing blow across the northern zones. The best dynamics will
remain well up into BC. A weak warm front will swing through on
Monday. This will increase mid and high level cloud cover. The
cold front will then swing in Monday night. Neither front shows
much lift and only some light showers will be possible. Best
chances for precip will be across the northern mtns. Temperatures
will see a slight warming trend, but will still remain near to or
slightly below normal. /SVH

Tuesday night through Sunday. A broad upper-level trough will
remain anchored over the Pacific Northwest during this time-
frame. Confidence is near to above normal that cooler temperatures
will be here to stay with afternoon highs in the 60s to 70s.
Overnight lows will largely be in the 40s to 50s with pockets of
30s in the northern valleys and on the highest peaks.
Precipitation chances will be centered around the timing and track
of embedded shortwaves pivoting within the mean trough. Models
suggest the first of these waves swings through the region Tuesday
night into Wednesday. Precipitation amounts do not look terribly
impressive but at this point, anything will help. There is lower
confidence regarding the track and time of the next slug of energy
so will trend pops toward climatology which mainly mentions a
chance of showers in the mountains. With the cooler trough aloft,
afternoon instability may be sufficient in generating light
showers each afternoon. As for thunder, the main threat looks to
be in the higher terrain near the International Border Wednesday
afternoon and early evening. As for winds...breezy conditions are
possible each afternoon but the main periods we will emphasis
given the wildfires in the region will be Wednesday and Friday. A
cold front on Wednesday will bring a moderate push of winds with a
majority of the Basin looking at sustained winds from 15 to 25 and
gusts toward 35 mph. Similar winds could be experienced on ridge
tops. These winds will be from the southwest. On Friday, a cold
front drops in from the north bringing a northerly push of winds
through the region. The narrow and N-S oriented valleys of
Okanogan Valley and Purcell Trench will receive the brunt of this
wind but northerly winds can be anticipated region-wide. Speeds
have been increased between 10-15 mph with this forecast package
and may need to come up further. Stay tuned. /sb

.AVIATION...
00Z TAFS: Scattered showers and isolated thunderstorms will
affect extreme northeast WA and the northern panhandle of ID
behind a cold front moving into western Montana. Breezy west to
southwest winds will diminish after 03Z. Low level moisture from
recent rainfall and light upslope flow may allow MVFR ceilings in
low stratus to form between around 10Z to 16Z...affecting
KGEG/KSFF/KCOE. KPUW could also see MVFR conditions but
confidence is low. /EK

231 PM PDT SUN AUG 30 2015

.SYNOPSIS...
Showers, thunderstorms and breezy winds will wane through the
evening hours as a vigorous upper level weather system exits the
region. A cool, occasionally breezy and showery weather pattern
is expected much of next week.

&&

.DISCUSSION...

Tonight: Isolated to scattered showers will continue into the
early evening as the upper level trough of low pressure crosses
the region. Much of this shower activity will be located across
the eastern half of the forecast area. Isolated thunderstorms will
also be possible through the early evening. I don`t think we will
be able to generate enough instability for thunderstorms to be a
big threat. Strongest storms are expected to be across the
northern mountains with small hail, heavy downpours and gusty
winds to 40 mph possible.

Monday through Tuesday: Another shortwave trough will swing by the
region on Monday and Monday night. This system will mostly be a
glancing blow across the northern zones. The best dynamics will
remain well up into BC. A weak warm front will swing through on
Monday. This will increase mid and high level cloud cover. The
cold front will then swing in Monday night. Neither front shows
much lift and only some light showers will be possible. Best
chances for precip will be across the northern mtns. Temperatures
will see a slight warming trend, but will still remain near to or
slightly below normal. /SVH

Tuesday night through Sunday. A broad upper-level trough will
remain anchored over the Pacific Northwest during this time-
frame. Confidence is near to above normal that cooler temperatures
will be here to stay with afternoon highs in the 60s to 70s.
Overnight lows will largely be in the 40s to 50s with pockets of
30s in the northern valleys and on the highest peaks.
Precipitation chances will be centered around the timing and track
of embedded shortwaves pivoting within the mean trough. Models
suggest the first of these waves swings through the region Tuesday
night into Wednesday. Precipitation amounts do not look terribly
impressive but at this point, anything will help. There is lower
confidence regarding the track and time of the next slug of energy
so will trend pops toward climatology which mainly mentions a
chance of showers in the mountains. With the cooler trough aloft,
afternoon instability may be sufficient in generating light
showers each afternoon. As for thunder, the main threat looks to
be in the higher terrain near the International Border Wednesday
afternoon and early evening. As for winds...breezy conditions are
possible each afternoon but the main periods we will emphasis
given the wildfires in the region will be Wednesday and Friday. A
cold front on Wednesday will bring a moderate push of winds with a
majority of the Basin looking at sustained winds from 15 to 25 and
gusts toward 35 mph. Similar winds could be experienced on ridge
tops. These winds will be from the southwest. On Friday, a cold
front drops in from the north bringing a northerly push of winds
through the region. The narrow and N-S oriented valleys of
Okanogan Valley and Purcell Trench will receive the brunt of this

scattered showers and isolated thunderstorms behind the cold
front. Sunshine will be necessary to destabilize the atmosphere
sufficiently for these cells. Only a handful of lightning
strikes are expected at this time. Breezy west to southwest winds

Area Forecast Discussion
National Weather Service Spokane WA
1051 AM PDT SUN AUG 30 2015

.SYNOPSIS...
A vigorous upper level disturbance will bring the Inland
Northwest some much needed rain today. Area wildfires will have a
good chance of a tenth to a quarter inch of rain. A cool,
occasionally breezy and showery weather pattern is expected much
of next week.


&&

.DISCUSSION...
Morning forecast update: The 700 mb cold front is just now
beginning to cross east of the Cascade crest at 9:00 AM this
morning. Low levels have moistened up considerably after
yesterday`s cold front passage. This has resulted in a more
proficient rain producing front for this morning compared to
yesterday. Current radar shows a widespread coverage of showers
developing ahead of the front east of a line from Moses Lake to
Ritzville. Expect these showers to continue across the eastern half
of the forecast area through this morning. Best chances for
showers will be in the Panhandle for the afternoon as low levels
turn more westerly with orographic enhancement playing a bigger
role in shower development. Expect light to moderate rainfall with
these showers through the morning into the early afternoon.

Chances for thunderstorms will increase late this morning into the
early afternoon over the western basin up into the Okanogan
Valley/Highlands. Visible satellite imagery shows the cloud cover
dispersing a bit behind the frontal passage. This will result in
better surface heating that will combine with a relatively moist
boundary layer with dew points in the low to mid 50s. We will see
the possibility for thunderstorms increasing eastward through the
afternoon as the upper level trough pushes across the region.
Thunderstorms will be possible over the Northern Blue Mtns,
Palouse, Spokane Area and Northeast Mtns after about 1:00 PM PDT,
then push into the Panhandle by about 3:00 PM PDT this afternoon.

The convection will increase the wind potential. Winds will
generally be breezy with gusts to around 30 mph with today`s cold
front passage. Thunderstorms that develop will be capable of
drawing down stronger gusts in the 40-50 mph range with the stronger
cells being capable to producing gusts closer to this upper range.
These stronger gusts are not expected to be widespread as
thunderstorm coverage will be isolated to scattered and the
stronger gusts will likely be confined to near the thunderstorms
themselves. Other potential impacts from thunderstorms today will
include small hail and heavy downpours. The good news with the
heavy rain aspect of the thunderstorms is that they are expected
to be moving at a good pace to the east. This should limit the
potential for any Flash Flooding with the risk looking low today.
However, burn scared areas may see some minor mud or debris flows
with thunderstorms. /SVH

1051 AM PDT SUN AUG 30 2015

.SYNOPSIS...
A vigorous upper level disturbance will bring the Inland
Northwest some much needed rain today. Area wildfires will have a
good chance of a tenth to a quarter inch of rain. A cool,
occasionally breezy and showery weather pattern is expected much
of next week.


&&

.DISCUSSION...
Morning forecast update: The 700 mb cold front is just now
beginning to cross east of the Cascade crest at 9:00 AM this
morning. Low levels have moistened up considerably after
yesterday`s cold front passage. This has resulted in a more
proficient rain producing front for this morning compared to
yesterday. Current radar shows a widespread coverage of showers
developing ahead of the front east of a line from Moses Lake to
Ritzville. Expect these showers to continue across the eastern half
of the forecast area through this morning. Best chances for
showers will be in the Panhandle for the afternoon as low levels
turn more westerly with orographic enhancement playing a bigger
role in shower development. Expect light to moderate rainfall with
these showers through the morning into the early afternoon.

Chances for thunderstorms will increase late this morning into the
early afternoon over the western basin up into the Okanogan
Valley/Highlands. Visible satellite imagery shows the cloud cover
dispersing a bit behind the frontal passage. This will result in
better surface heating that will combine with a relatively moist
boundary layer with dew points in the low to mid 50s. We will see
the possibility for thunderstorms increasing eastward through the
afternoon as the upper level trough pushes across the region.
Thunderstorms will be possible over the Northern Blue Mtns,
Palouse, Spokane Area and Northeast Mtns after about 1:00 PM PDT,
then push into the Panhandle by about 3:00 PM PDT this afternoon.

The convection will increase the wind potential. Winds will
generally be breezy with gusts to around 30 mph with today`s cold
front passage. Thunderstorms that develop will be capable of
drawing down stronger gusts in the 40-50 mph range with the stronger
cells being capable to producing gusts closer to this upper range.
These stronger gusts are not expected to be widespread as
thunderstorm coverage will be isolated to scattered and the
stronger gusts will likely be confined to near the thunderstorms
themselves. Other potential impacts from thunderstorms today will
include small hail and heavy downpours. The good news with the
heavy rain aspect of the thunderstorms is that they are expected
to be moving at a good pace to the east. This should limit the
potential for any Flash Flooding with the risk looking low today.
However, burn scared areas may see some minor mud or debris flows
with thunderstorms. /SVH

&&

.AVIATION...
18Z TAFS: Bands of rain will accompany the passage of a cold
front today. The most significant precipitation will occur over
the Idaho Panhandle between 18z-22z with ceilings occasionally
falling into the 2500-4000 ft range. There may also be some
scattered showers and isolated thunderstorms behind the cold
front. Sunshine will be necessary to destabilize the atmosphere
sufficiently for these cells. Only a handful of lightning
strikes are expected at this time. Breezy west to southwest winds
will follow the cold front passage in the 20z-02z time frame with
gusts to 20-30kts. /GKoch

.DISCUSSION...

Today and tonight...Longwave trof hanging over a good portion of
the Western US allows a wet cold front to pass through it today.
Pops remain high with such a scenario given the favorable long-
wave trof placement and a somewhat well maintained moisture feed
extending into it from the south/southwest overcoming the lee side
rain-shadow of the Cascades. 0-6km AGL winds suggest storm motion
to the northeast and east at about 25 to 35 mph today. This storm
motion is fast enough to continue to note that flash flooding on
area burn scars is not likely with today`s rainfall. The -20 to
-22 deg Celsius 500mb cold pool contained in the trof is on the
order of two standard deviations on the cols side of what would be
considered normal for this time of year, therefore a mention of
thunder seems reasonable given the resulting instability of having
this cold pool aloft. Forecast temperatures on the cool side of
normal a given due to this trof and the resulting rainfall keeping
the daytime high on the cold side while more effective radiational
cooling is likely tonight under this trof. Robust winds from the
southwest remain as well today that will decrease a bit tonight
but likely not go calm given the dynamic nature of the the above
scenario. /Pelatti

Monday through Saturday...Model agreement is pretty good between
the latest GFS and EC runs with details and run to run
consistency is very good regarding the overall concept of a
persistently troffy pattern enveloping the region through the work
week. A huge parent trough over western Canada will promote a
series of disturbances brushing or enveloping the forecast area
during the week. A well directed fetch of Pacific moisture will
probably benefit from some isentropic and orographic enhancement
into the Cascades and northern mountains on Monday. Tuesday may be
a relatively dry day with a few degrees of warming before the next
trough carves into the region with another cold front on or about
Wednesday with the actual trough lingering over the region through
Friday. This argues strongly for a period of cooler than normal
temperatures...occasional periods of showers mostly on the
mountains but with a few opportunities for basin precipitation as
well. All this will be good news for the fire fighting
efforts...but the fly in the ointment will be the propensity for
breezy and occasionally gusty conditions across the basin
especially but also on the mid-slopes and ridges of the mountains
surrounding the basin...which may hamper firefighting. Monday and
especially Wednesday look like the breeziest days...with Wednesday
in particular shaping up to be quite windy and gusty in the wake
of an early day cold front passage.

Way out on or about Saturday the models suggest a pattern shift
back to a drying and warming weak ridge rebound over the region.

.AVIATION...
12Z TAFS: The next 12 or so hours will potentially be the wettest
as a wet frontal zone works its way through the area. Winds will
be gusty but considerably lesser in comparison to yesterday. Smoke
from area fires may impact TAF sites again...especially KPUW and
KLWS possibly resulting in IFR ceilings and visibilities. After
02Z Monday the expectation is less wind and an end to
precipitation and a return to mostly VFR conditions, with the

A vigorous upper level disturbance will bring the Inland

.SYNOPSIS...
Look for the wind to decrease early this evening as our fast
moving cold front moves out of the Inland Northwest. A vigorous
upper level disturbance will bring the Inland Northwest some much
needed rain on Sunday. Area wildfires will have a good chance of a
tenth to a quarter inch of rain. A cool and moist weather pattern
is expected much of next week.


&&

.DISCUSSION...
Evening update to allow the remaining Red Flag Warnings and Wind
Advisories to expire as winds diminish and relative humidity is
recovering. South to southwest winds will remain breezy across
the area with occasional gusts of 25 to 35 mph possible this
evening but advisory criteria winds are no longer expected.
Visibility has also improved across the region as gusty winds
diminish and will no longer loft the dust into the air. Most of
the showers that followed the frontal passage have moved off into
Montana this evening, but another batch of precipitation is
affecting western WA and the Cascade crest. This is associated
with the upper trough that will pivot across the region later
tonight and Sunday. More showers will be on the way overnight
along with a slight chance of thunderstorms under the cold pool
aloft. These showers should bring a better chance of wetting rains
to area wildfires. Areas of smoke will pool in some of the
valleys tonight as the inversion sets up but any showers will help
to limit this. /Kelch

Area Forecast Discussion
National Weather Service Spokane WA
800 PM PDT SAT AUG 29 2015

.SYNOPSIS...
Look for the wind to decrease early this evening as our fast
moving cold front moves out of the Inland Northwest. A vigorous
upper level disturbance will bring the Inland Northwest some much
needed rain on Sunday. Area wildfires will have a good chance of a
tenth to a quarter inch of rain. A cool and moist weather pattern
is expected much of next week.


&&

.DISCUSSION...
Evening update to allow the remaining Red Flag Warnings and Wind
Advisories to expire as winds diminish and relative humidity is
recovering. South to southwest winds will remain breezy across
the area with occasional gusts of 25 to 35 mph possible this
evening but advisory criteria winds are no longer expected.
Visibility has also improved across the region as gusty winds
diminish and will no longer loft the dust into the air. Most of
the showers that followed the frontal passage have moved off into
Montana this evening, but another batch of precipitation is
affecting western WA and the Cascade crest. This is associated
with the upper trough that will pivot across the region later
tonight and Sunday. More showers will be on the way overnight
along with a slight chance of thunderstorms under the cold pool
aloft. These showers should bring a better chance of wetting rains
to area wildfires. Areas of smoke will pool in some of the
valleys tonight as the inversion sets up but any showers will help
to limit this. /Kelch

&&

.AVIATION...
00Z TAFS: Strong west or southwest wind gusts are starting to
diminish as the cold front moves east to Montana. A line of
showers associated with the front has cleared some of the smoke
out of the area. Showers will continue to track east across N
Idaho this evening. Still expect some local reductions in
visibility in blowing dust through about 02Z but this should
dissipate as gusty winds lessen after sunset. The upper level
trough will slide over the region tonight into Sunday with
scattered showers possible along with isolated afternoon
thunderstorms. All TAF sites will likely be affected by -SHRA at
some point with the most likely time period between 14Z- 20Z with
the passage of the cold pool aloft. Confidence is low that any TAF
site will see thunderstorms but the more favorable site is KCOE
after 18Z Sunday. Smoke may again affect the region if area
wildfire flare up again but confidence remains low on timing and
location of smoke plumes. /EK

Made a few updates to the forecast. Big story - winds are
subsiding. Visibilities have improved across the Columbia Basin
with no new road closures or incidents. So have allowed the dust
storm warning to end and put a wind advisory in its place through
7 pm. Also took down wind advisories from the northeast WA
mountains...Okanogan highlands and much of north Idaho as the
showers have tempered the winds a bit. Remaining areas will
continue to see the winds and the wind advisory remains. Gradients
and winds will continue to relax during the next few hours.
Likewise, the red flag warning in north Idaho was canceled early
as winds have decreased and humidities have risen. /rfox.

528 PM PDT SAT AUG 29 2015

.SYNOPSIS...
Look for the wind to decrease early this evening as our fast
moving cold front moves out of the Inland Northwest. A vigorous
upper level disturbance will bring the Inland Northwest some much
needed rain on Sunday. Area wildfires will have a good chance of a
tenth to a quarter inch of rain. A cool and moist weather pattern
is expected much of next week.

&&

.DISCUSSION...
Made a few updates to the forecast. Big story - winds are
subsiding. Visibilities have improved across the Columbia Basin
with no new road closures or incidents. So have allowed the dust
storm warning to end and put a wind advisory in its place through
7 pm. Also took down wind advisories from the northeast WA
mountains...Okanogan highlands and much of north Idaho as the
showers have tempered the winds a bit. Remaining areas will
continue to see the winds and the wind advisory remains. Gradients
and winds will continue to relax during the next few hours.
Likewise, the red flag warning in north Idaho was canceled early
as winds have decreased and humidities have risen. /rfox.

&&

.AVIATION...
00Z TAFS: Strong west or southwest wind gusts are starting to
diminish as the cold front moves east to Montana. A line of
showers associated with the front has cleared some of the smoke
out of the area. Showers will continue to track east across N
Idaho this evening. Still expect some local reductions in
visibility in blowing dust through about 02Z but this should
dissipate as gusty winds lessen after sunset. The upper level
trough will slide over the region tonight into Sunday with
scattered showers possible along with isolated afternoon
thunderstorms. All TAF sites will likely be affected by -SHRA at
some point with the most likely time period between 14Z- 20Z with
the passage of the cold pool aloft. Confidence is low that any TAF
site will see thunderstorms but the more favorable site is KCOE
after 18Z Sunday. Smoke may again affect the region if area
wildfire flare up again but confidence remains low on timing and
location of smoke plumes. /EK

upper level disturbance will bring the Inland Northwest some much
needed rain on Sunday. Area wildfires will have a good chance of a
tenth to a quarter inch of rain. A cool and moist weather pattern

&&

.DISCUSSION...
Tonight: The cold front has now pushed north of the region into
BC. The strongest gusts have likely passed now that the strong
cold air advection with the front has subsided. Much of the winds
for the rest of this afternoon into the early evening will be
gradient driven. Models show the strongest winds occurring across
the western basin, on the Waterville Plateau and up the Okanogan
Valley. This is where the tightest portion of the gradient will
be. There may also be some wind tunneling effect as the winds flow
up the Okanogan Valley as well that will provide some additional
enhancement. Expect these areas to see sustained wind speeds of
25 to 35 mph with gusts up to 50 mph possible through about 5:00
PM this afternoon before beginning to subside in the evening. The
basin and Waterville Plateau will also see a significant blowing
dust threat with visibility down to one-quarter mile at times. We
will leave the Dust Storm Warning out for these areas. We did go
ahead and cancelled the Dust Storm Warning for the Spokane Area
and WA Palouse and replaced it with a Wind Advisory for the rest
of this afternoon and evening. Wind speeds will be a bit weaker
here more in the range of 25 to 30 mph sustained wind speeds with
gusts generally only up to 45 mph for the remainder of the
afternoon and early evening. The current line of showers over
extreme eastern WA will push into the ID Panhandle by the early
evening and then move out of the region late this evening. Another
round of showers will move into the Cascades this evening with
rain spreading into eastern WA overnight into Sunday. /SVH

Sunday: The heart of the upper level trough will pass over
eastern Washington and north Idaho on Sunday. The 500mb cold pool
is expected to be in the -20C to -22C range and resembles a
vigorous autumn storm system. The GFS, NAM and ECMWF wring out a
good deal of moisture along the 700-500mb cold front. This system
should bring the most widespread rains we have seen in weeks.
There is good agreement between the models that widespread rain
amounts of a tenth to a quarter of an inch will fall from north
central Washington through northeast Washington into the Idaho
Panhandle. Forecast soundings suggest a small possibility of
lightning embedded in the rain showers Sunday, but thunderstorms
should not be the kind that produce flash flooding. We may see
some highly localized rock slides and small debris flows in the
burn areas, but life-threatening flash flooding looks highly
unlikely with this fall-type storm system. Sunday will be breezy
in the afternoon with gusts of 20 to 30 mph, but morning rainfall
and much cooler/humid conditions will diminish our chance for
blowing dust.

Monday and Tuesday: The upper level trough will reload along the
coast of British Columbia Monday and Tuesday. It looks like the
Inland Northwest will remain under a cool, but mainly dry west to
southwest flow. Showers look to be mainly confined to the Cascade
Crest and the mountains along the Canadian border. The strong on-
shore flow in the mid-levels will produce a tight surface pressure
gradient which will result in breezy winds across the Palouse,
West Plains, and Columbia Basin. /GKoch

Tuesday night through Saturday...Cooler and continued unsettled
weather will be persisted through the rest of the week. The models
have been advertising an upper level trough that will swing over
the region. The confidence of the trough`s timing and speed was
marginal but the confidence seems to have increased with the 12z
models. The GFS and ECMWF agree on a slower timing showing the
cold core rotating across southern B.C. This pattern seems to be
more late fall like instead of early September. Anticipate showery
conditions primarily near the Canadian border being closer to the
low center and being enhanced during the afternoon and evening
hours. Did add a slight chance of thunderstorms embedded in the
showers associated with the cold air aloft and the best
instability. This will be best chance for the active convection
will be over north central Washington on Wednesday, then shifting
across northeast Washington and north Idaho on Thursday and
Friday. Occasional breeziness will develop in the afternoon and
evening especially across the Columbia Basin. Will continue to
include patchy smoke across the region, mainly near the wild fires
and following the downstream wind patterns. There is some thought
that the winds and precipitation may help disperse the smoke as
the weather pattern remains active. Expect temperatures running
below normal for early September, with daytime highs in the 70s.
/rfox.

&&

.AVIATION...
18Z TAFS: The combination of smoke and blowing dust will
contribute to visibility problems that are difficult to forecast.
Look for frequent amendments through the early evening. Strong
west or southwest wind gusts are expected to max by early
afternoon right behind the cold front. The poorest blowing dust
visibility will likely occur at Moses Lake, Spokane, and possibly
Pullman due to dryland wheat fields upwind of these airports.
Visibility restrictions due to smoke in Lewiston should improve
through the day as wind disperses smoke. /GKoch

1234 PM PDT SAT AUG 29 2015

.SYNOPSIS...
A cold front will push through the Inland Northwest today and
bring high winds to the region. This will create a situation for
blowing dust with reduced visibility. There is the potential for
toppled trees and downed power lines as well. A cooler and
occasionally breezy regime with some shower activity will persist
through the next week.

&&

.DISCUSSION...
Early afternoon forecast update. Radar shows two distinct bands of
precip. One is extending just east of Lewiston and up to the
northeast toward Kellogg. We have had reports of gusts near 70 MPH
in the town Lewiston. This may be partial mountain wave activity
off of the Northeast Blue Mtns and stronger momentum transfer with
the showers. Gusts of this magnitude are expected to be temporary
within less of an hour and isolated in coverage. We have elected
to cover these stronger gusts with a Significant Weather Advisory
through 1:00 PM on top of the Windy Advisory already in effect.
Another Significant Weather Advisory may be needed if these
stronger gusts continue past 1:00 PM; however, much of these
stronger gusts are expected to be east of the area around this
time. Expect the potential for very strong winds to extend with
this band of showers across the Central Panhandle Mtns and on the
Camas Prairie.

The next batch of showers out ahead of the mid level cold front
can be seen on radar extending from Walla Walla to Republic. These
showers will increase in coverage to the east through the rest of
the afternoon. A few hundredths to a tenth of an inch of precip
can be expected from these showers. Best potential for closer to a
tenth of an inch is expected over the northern mtns. Much of the
basin may only just see some sprinkles from these showers. High
resolution models show a resurgence of stronger winds across the
western basin northward into the Okanogan Valley is expected as
this front passes. Sustained winds of closer to 25 to 30 mph with
gusts to between 40 to 50 mph can be expected with this second
surge. These wind speeds will still be strong enough to pick up
dust, but blowing dust may be more isolated now that some
rainfall has fallen. No updates to the Wind Advisory or Dust Storm
Warning at this time. /SVH

can be seen on radar extending from Walla Walla to Republic. These
showers will increase in coverage to the east through the rest of
the afternoon. A few hundredths to a tenth of an inch of precip
can be expected from these showers. Best potential for closer to a
tenth of an inch is expected over the northern mtns. Much of the
basin may only just see some sprinkles from these showers. High
resolution models show a resurgence of stronger winds across the
western basin northward into the Okanogan Valley is expected as
this front passes. Sustained winds of closer to 25 to 30 mph with
gusts to between 40 to 50 mph can be expected with this second
surge. These wind speeds will still be strong enough to pick up
dust, but blowing dust may be more isolated now that some
rainfall has fallen. No updates to the Wind Advisory or Dust Storm
Warning at this time. /SVH

.AVIATION...
18Z TAFS: The combination of smoke and blowing dust will
contribute to visibility problems that are difficult to forecast.
Look for frequent amendments through the early evening. Strong
west or southwest wind gusts are expected to max by early
afternoon right behind the cold front. The poorest blowing dust
visibility will likely occur at Moses Lake, Spokane, and possibly
Pullman due to dryland wheat fields upwind of these airports.
Visibility restrictions due to smoke in Lewiston should improve
through the day as wind disperses smoke. /GKoch

Area Forecast Discussion
National Weather Service Spokane WA
1234 PM PDT SAT AUG 29 2015

.SYNOPSIS...
A cold front will push through the Inland Northwest today and
bring high winds to the region. This will create a situation for
blowing dust with reduced visibility. There is the potential for
toppled trees and downed power lines as well. A cooler and
occasionally breezy regime with some shower activity will persist
through the next week.

&&

.DISCUSSION...
Early afternoon forecast update. Radar shows two distinct bands of
precip. One is extending just east of Lewiston and up to the
northeast toward Kellogg. We have had reports of gusts near 70 MPH
in the town Lewiston. This may be partial mountain wave activity
off of the Northeast Blue Mtns and stronger momentum transfer with
the showers. Gusts of this magnitude are expected to be temporary
within less of an hour and isolated in coverage. We have elected
to cover these stronger gusts with a Significant Weather Advisory
through 1:00 PM on top of the Windy Advisory already in effect.
Another Significant Weather Advisory may be needed if these
stronger gusts continue past 1:00 PM; however, much of these
stronger gusts are expected to be east of the area around this
time. Expect the potential for very strong winds to extend with
this band of showers across the Central Panhandle Mtns and on the
Camas Prairie.

The next batch of showers out ahead of the mid level cold front
can be seen on radar extending from Walla Walla to Republic. These
showers will increase in coverage to the east through the rest of
the afternoon. A few hundredths to a tenth of an inch of precip
can be expected from these showers. Best potential for closer to a

1026 AM PDT SAT AUG 29 2015

.SYNOPSIS...
A cold front will push through the Inland Northwest today and
bring high winds to the region. This will create a situation for
blowing dust with reduced visibility. There is the potential for
toppled trees and downed power lines as well. A cooler and
occasionally breezy regime with some shower activity will persist
through the next week.

&&

.DISCUSSION...
A third update this morning to expand the Dust Storm Warning
further north to include the Spokane Area and the Waterville
Plateau. Current radar shows a gust front moving southwest to
northeast on the Spokane West Plains. Radar estimates gusts up to
40 mph approaching the Spokane Area. Web cams, Facebook and
Twitter reports suggest visibility down to 1 mile or less due to
the blowing dust. Isolated spots of near zero visibility may be
possible. These conditions may result treacherous travel
conditions with the worst spots expected to be across the basin.
We have also received a spotter report of winds at 40 mph with
gusts to around 50 mph in Mansfield with visibility down to 1/4
mile. /SVH

&&

.AVIATION...
12Z TAFS: A vigorous cold front passage today will cause the winds
to increase and shift during the aviation period along with some
spells of LLWS this morning. When winds reach peak this afternoon
the mixing of the smoke will be replaced with some blowing dust
to impact visibilities (possibly down to IFR near KMWH this
afternoon). Showers (and some thunderstorms) that form will move
quickly to the Northeast at 40 mph or more which won`t allow much
precipitation to fall in one place. High wind watch remains in
place for today. Decrease in wind and blowing dust expected in
very late afternoon and early evening. /Pelatti

toppled trees and downed power lines as well. A cooler and
occasionally breezy regime with some shower activity will persist
through the next week.

.DISCUSSION...
Today and Tonight...Numerous highlights in effect to address the
impacts resulting from the vigorous cold front passage today. A
red flag warning and a high wind watch for just about all of the
forecast area (with the exception of some portions of the
Washington Cascades) is in effect for today and this evening. The
red flag warning will stay as is but the plan is for the high wind
watch to be upgraded between 7 and 8am PDT this morning for
optimal dissemination. An air quality alert message remains in
effect until further notice addressing the health impacts and
protective precautions that can be taken to protect oneself from
wildfire smoke and blowing dust. For brevity I won`t repeat the
call to actions and other useful content contained in those
highlights here but encourage all reading this discussion to pull
them up and look them over (many of them will be noted in social
network posts and imagecasts).

As far as model differences, well I see good consistency as far
as timing and placement of the front with its passage today and
tonight. Of particular note is the Ensemble Situational Awareness
Tables noting some of the wind at 850mb (around 5000 feet MSL)
over the area at 11am PDT today are on the order of 5 to 6
standardized anomalies above the mean climatology data between
1979-2009. That would signify these to be very rare and extreme
winds for this time of year which supports the current wind
forecast and resulting highlights.

Precipitation amounts will decrease substantially across the
crest due to the typical lee side rain-shadow of the Washington Cascades.
Any convection that forms will be moving with a quick storm
motion to the northeast at 40 mph. This is too fast to allow
substantial precipitation to fall in one place so the amounts
expected remain on the light side.

/Pelatti

Sunday through Friday....Models are in general agreement in
establishing and maintaining through the next week a huge closed
upper low over western Canada with a sprawling surface low
pressure underneath it. This pattern creates high confidence of a
continued active pattern featuring multiple spur troughs sweeping
through the region dragging cold fronts bearing occasional showers
and cooler than normal temperatures. The persistent southerly
gradient feeding onto the surface low will promote breezy
southwesterly winds much of the time especially over the exposed
terrain of the eastern basin. Rain showers and possibly even some
high elevation snow will be the feature of just about every day
through Friday in the mountains surrounding the basin...with a
chance of showers in the basin on those days where a spur trough
sweeps through...at this time almost definitely Sunday...again on
Tuesday or Wednesday depending on which model is used...and
possibly yet again on or about Thursday. /Fugazzi

.AVIATION...
12Z TAFS: A vigorous cold front passage today will cause the winds
to increase and shift during the aviation period along with some
spells of LLWS this morning. When winds reach peak this afternoon
the mixing of the smoke will be replaced with some blowing dust
to impact visibilities (possibly down to IFR near KMWH this
afternoon). Showers (and some thunderstorms) that form will move
quickly to the Northeast at 40 mph or more which won`t allow much
precipitation to fall in one place. High wind watch remains in
place for today. Decrease in wind and blowing dust expected in
very late afternoon and early evening. /Pelatti

06Z TAFS: A cold front will continue to approach the coast tonight
and shift across the region between Saturday morning and early
afternoon. Overnight developing inversions will bring the threat
of MVFR visibility from smoke. Some LLWS is projected just ahead
of the cold front. That front is expected to pass between 15 and
19Z, which will bring strong winds to the surface across the
region but especially from MWH to GEG with possible gusts over 50
mph. High Wind Watches are in place. As a result of the winds
blowing dust is expected, with localized MVFR/IFR vis. The better
threat of IFR (even LIFR) vis will be across the Columbia Basin,
around MWH and MVFR elsewhere. Some showers are possible. The
best threat will be within the Cascades and northern mountains.
There is also a threat of some afternoon thunderstorms around the
mountains. As for TAF sites, the best shower threat will be near
EAT and PUW. Elsewhere there will be some shower potential but
confidence is low. Winds may begin to abate some in the late

.SYNOPSIS...
A cold front will push through the Inland Northwest on Saturday
and bring high winds to the region. This will create a situation
for blowing dust with reduced visibility. There is the potential
for toppled trees and downed power lines as well. A cooler and
occasionally breezy regime with some shower activity will persist
through the next week.

.DISCUSSION...
Evening update: forecast in generally on track. The strong cold
front is pushing on the north CA/southwest OR coast and heading
northeastward and is generally on track to pass east of the
Cascades tomorrow morning, generally in the next 9 to 12 hours. No
real changes made to the ongoing forecast. /J. Cote`

&&

.AVIATION...
06Z TAFS: A cold front will continue to approach the coast tonight
and shift across the region between Saturday morning and early
afternoon. Overnight developing inversions will bring the threat
of MVFR visibility from smoke. Some LLWS is projected just ahead
of the cold front. That front is expected to pass between 15 and
19Z, which will bring strong winds to the surface across the
region but especially from MWH to GEG with possible gusts over 50
mph. High Wind Watches are in place. As a result of the winds
blowing dust is expected, with localized MVFR/IFR vis. The better
threat of IFR (even LIFR) vis will be across the Columbia Basin,
around MWH and MVFR elsewhere. Some showers are possible. The
best threat will be within the Cascades and northern mountains.
There is also a threat of some afternoon thunderstorms around the
mountains. As for TAF sites, the best shower threat will be near
EAT and PUW. Elsewhere there will be some shower potential but
confidence is low. Winds may begin to abate some in the late
afternoon and the blowing dust should abate too. /J. Cote`

.DISCUSSION...

...STRONG LOW PRESSURE SYSTEM TO DELIVER VERY STRONG WINDS AND
AREAS OF BLOWING DUST ON SATURDAY...

Tonight through Saturday: The highly advertised low pressure
system is beginning to take shape out at 130W/40N off of the
northern California coast. The surface low will continue to deep
ahead of a dynamic upper level shortwave trough of lower pressure.
The track will take the low up the coast line tonight. Additional
cyclogenesis will take place in the lee of the Cascades over
south-central WA early Saturday morning and track northward into
southern BC through the late morning hours. The associated cold
front will result in strong cold air advection that is expected to
result in good momentum mixing with much strong winds a loft
mixing down to the surface. The track of the low across the basin
and across the northern mountains of eastern WA will place the
strongest winds across this part of the region. With that said,
all areas will likely experience windy conditions. Most of the
rainfall with the front will occur across the east slopes of the
northern Cascade Mtns with only a chance expected in the post
frontal air mass across much of the rest of the region.

* Winds: Sustained winds of 25 to 35 mph with gusts to between 50
  to 60 mph will be possible with frontal passage from the late
  morning hours into the early afternoon. Gusts more into the 40
  to 50 mph range will be more likely later in the afternoon as
  the surface low pushes further away from the region. High
  profile vehicles will likely have a difficult time due to strong
  cross winds. Southerly winds will result in the strongest cross
  winds occurring along I-90 and Highway 2 across the basin.
  Strong cross winds can also be expected along Highway 95 and 195
  across the Palouse.

* Blowing Dust: The basin is not expected to receive much precip
  between now through Saturday afternoon. The strong winds through
  the day on Saturday is expected to present a potential dangerous
  blowing dust concern. The basin will be the greatest concern for
  blowing dust. Visibility may drop down to a 1/4 mile very
  quickly making for dangerous travel conditions. The blowing dust
  may stretch as far east as the Spokane/Coeur d`Alene Areas,
  Palouse and as far north as over the Waterville Plateau and
  Okanogan Valley.

* Precipitation: Around a quarter of inch to three-quarters of
  rain can be expected across the east slopes of the northern
  Cascades Mtns. Higher accumulations are expected closer to the
  crest with localized amounts of near an inch possible tonight
  into Saturday. Much of this rainfall will occur in low to
  moderate rainfall intensities. There will be a slight chance of
  convection behind the cold front late in the morning into the
  early afternoon. This may result in some higher rainfall
  intensities near the burn scars in the Cascades. Minor mud or
  debris flows will be possible in and around recent burn scars,
  but Flash Flooding is not expected.

Sunday: A second cold front will swing through the region. This
front will be wetter east of the Cascade Mountains. Rainfall
amounts of near a tenth of an inch with localized amounts near one
quarter of an inch will be possible across the eastern half of WA.
Thunderstorms will also be possible in the afternoon behind the
cold front. Some of these storms may pulse up quickly with near
500-800 J/KG of CAPE exhibited off of the NAM model. Upper level
winds will still be very strong and any convection may draw down
these stronger winds toward the surface. Best chances for
thunderstorms are expected across the northern mountains of WA and
ID, but a chance of thunderstorms will be possible across the
basin as well that push east through the afternoon.

Monday and Monday night: A cool and showery pattern will continue
into early next week. Best chance for showers are expected across
the northern half of the forecast area. Temperatures will be
below normal with highs both Sunday and Monday in the 60s and 70s.
/SVH

Tuesday through Friday: Cooler and more unsettled weather can be
expected for next week as an upper level trough remains over the
region. The center of the upper low pivots across northwest
Washington through Wednesday but the speed it takes to push across
Inland Northwest is not clear. The GFS wants to hold a highly
amplitude trough over the Pacific NW through the week, meanwhile
the ECMWF shows the low kicking out quicker and leaving a baggy
trough behind. The difference in the sensible weather will be
coverage of showers. Initially, a frontal band will push across
the Cascades Tuesday afternoon ahead of the upper trough and then
stall over southeast Washington into north Idaho by Wednesday and
even into Thursday. Anticipate the best chance of post frontal
showers to be with the low center across the northern zones. West
to southwest winds will become gusty at times especially over the
afternoon and evening hours. Will continue to keep patchy smoke in
forecast through the week mainly near the source regions, although
anticipate more smoke dispersion with the winds and precipitation.
Expect daytime temperatures in the 70s, running below normal for
early September. /rfox.

&&

.AVIATION...
00Z TAFS: The first weak impulse swing out of the region this
evening, with a few sprinkles possible. Overnight inversions
developing will bring the threat of MVFR visibility from smoke,
while a stronger cold front approaches from the west. Some LLWS is
projected just ahead of the cold front. That front is expected to
pass between 15 and 19Z, which will bring strong winds to the
surface across the region but especially from MWH to GEG with
possible gusts over 50 mph. High Wind Watches are in place. As a
result of the winds blowing dust is expected, with localized
MVFR/IFR vis. The better threat of IFR (even LIFR) vis will be
across the Columbia Basin, around MWH and secondarily toward the
GEG/SFF area. Some showers are possible. The best threat will be
within the Cascades and northern mountains. There is also a threat
of some afternoon thunderstorms around the mountains. As for TAF
sites, the best shower threat will be near EAT and PUW. Elsewhere
there will be some shower potential but confidence is low. Winds
may begin to abate some in the late afternoon. /J. Cote`

mixing down to the surface. The track of the low across the basin
and across the northern mountains of eastern WA will place the
strongest winds across this part of the region. With that said,
all areas will likely experience windy conditions. Most of the
rainfall with the front will occur across the east slopes of the
northern Cascade Mtns with only a chance expected in the post
frontal air mass across much of the rest of the region.

* Winds: Sustained winds of 25 to 35 mph with gusts to between 50
  to 60 mph will be possible with frontal passage from the late
  morning hours into the early afternoon. Gusts more into the 40
  to 50 mph range will be more likely later in the afternoon as
  the surface low pushes further away from the region. High
  profile vehicles will likely have a difficult time due to strong
  cross winds. Southerly winds will result in the strongest cross
  winds occurring along I-90 and Highway 2 across the basin.
  Strong cross winds can also be expected along Highway 95 and 195
  across the Palouse.

* Blowing Dust: The basin is not expected to receive much precip
  between now through Saturday afternoon. The strong winds through
  the day on Saturday is expected to present a potential dangerous
  blowing dust concern. The basin will be the greatest concern for
  blowing dust. Visibility may drop down to a 1/4 mile very
  quickly making for dangerous travel conditions. The blowing dust
  may stretch as far east as the Spokane/Coeur d`Alene Areas,
  Palouse and as far north as over the Waterville Plateau and
  Okanogan Valley.

* Precipitation: Around a quarter of inch to three-quarters of
  rain can be expected across the east slopes of the northern
  Cascades Mtns. Higher accumulations are expected closer to the
  crest with localized amounts of near an inch possible tonight
  into Saturday. Much of this rainfall will occur in low to
  moderate rainfall intensities. There will be a slight chance of
  convection behind the cold front late in the morning into the
  early afternoon. This may result in some higher rainfall
  intensities near the burn scars in the Cascades. Minor mud or
  debris flows will be possible in and around recent burn scars,
  but Flash Flooding is not expected.

Sunday: A second cold front will swing through the region. This
front will be wetter east of the Cascade Mountains. Rainfall
amounts of near a tenth of an inch with localized amounts near one
quarter of an inch will be possible across the eastern half of WA.
Thunderstorms will also be possible in the afternoon behind the
cold front. Some of these storms may pulse up quickly with near
500-800 J/KG of CAPE exhibited off of the NAM model. Upper level
winds will still be very strong and any convection may draw down
these stronger winds toward the surface. Best chances for
thunderstorms are expected across the northern mountains of WA and
ID, but a chance of thunderstorms will be possible across the
basin as well that push east through the afternoon.

Monday and Monday night: A cool and showery pattern will continue
into early next week. Best chance for showers are expected across
the northern half of the forecast area. Temperatures will be
below normal with highs both Sunday and Monday in the 60s and 70s.
/SVH

Tuesday through Friday: Cooler and more unsettled weather can be
expected for next week as an upper level trough remains over the
region. The center of the upper low pivots across northwest
Washington through Wednesday but the speed it takes to push across
Inland Northwest is not clear. The GFS wants to hold a highly
amplitude trough over the Pacific NW through the week, meanwhile
the ECMWF shows the low kicking out quicker and leaving a baggy
trough behind. The difference in the sensible weather will be
coverage of showers. Initially, a frontal band will push across
the Cascades Tuesday afternoon ahead of the upper trough and then
stall over southeast Washington into north Idaho by Wednesday and
even into Thursday. Anticipate the best chance of post frontal
showers to be with the low center across the northern zones. West
to southwest winds will become gusty at times especially over the
afternoon and evening hours. Will continue to keep patchy smoke in
forecast through the week mainly near the source regions, although
anticipate more smoke dispersion with the winds and precipitation.
Expect daytime temperatures in the 70s, running below normal for
early September. /rfox.

.AVIATION...
00Z TAFS: The first weak impulse swing out of the region this
evening, with a few sprinkles possible. Overnight inversions
developing will bring the threat of MVFR visibility from smoke,
while a stronger cold front approaches from the west. Some LLWS is
projected just ahead of the cold front. That front is expected to
pass between 15 and 19Z, which will bring strong winds to the
surface across the region but especially from MWH to GEG with
possible gusts over 50 mph. High Wind Watches are in place. As a
result of the winds blowing dust is expected, with localized
MVFR/IFR vis. The better threat of IFR (even LIFR) vis will be
across the Columbia Basin, around MWH and secondarily toward the
GEG/SFF area. Some showers are possible. The best threat will be
within the Cascades and northern mountains. There is also a threat
of some afternoon thunderstorms around the mountains. As for TAF
sites, the best shower threat will be near EAT and PUW. Elsewhere
there will be some shower potential but confidence is low. Winds
may begin to abate some in the late afternoon. /J. Cote`

...STRONG LOW PRESSURE SYSTEM TO DELIVER VERY STRONG WINDS AND
AREAS OF BLOWING DUST ON SATURDAY...

Tonight through Saturday: The highly advertised low pressure
system is beginning to take shape out at 130W/40N off of the
northern California coast. The surface low will continue to deep
ahead of a dynamic upper level shortwave trough of lower pressure.

  quickly making for dangerous travel conditions. The blowing dust
  may stretch as far east as the Spokane/Coeur d`Alene Areas,
  Palouse and as far north as over the Waterville Plateau and
  Okanogan Valley.

* Precipitation: Around a quarter of inch to three-quarters of
  rain can be expected across the east slopes of the northern
  Cascades Mtns. Higher accumulations are expected closer to the
  crest with localized amounts of near an inch possible tonight
  into Saturday. Much of this rainfall will occur in low to
  moderate rainfall intensities. There will be a slight chance of
  convection behind the cold front late in the morning into the
  early afternoon. This may result in some higher rainfall
  intensities near the burn scars in the Cascades. Minor mud or
  debris flows will be possible in and around recent burn scars,
  but Flash Flooding is not expected.

Sunday: A second cold front will swing through the region. This
front will be wetter east of the Cascade Mountains. Rainfall
amounts of near a tenth of an inch with localized amounts near one
quarter of an inch will be possible across the eastern half of WA.
Thunderstorms will also be possible in the afternoon behind the
cold front. Some of these storms may pulse up quickly with near
500-800 J/KG of CAPE exhibited off of the NAM model. Upper level
winds will still be very strong and any convection may draw down
these stronger winds toward the surface. Best chances for
thunderstorms are expected across the northern mountains of WA and
ID, but a chance of thunderstorms will be possible across the
basin as well that push east through the afternoon.

Monday and Monday night: A cool and showery pattern will continue
into early next week. Best chance for showers are expected across
the northern half of the forecast area. Temperatures will be
below normal with highs both Sunday and Monday in the 60s and 70s.
/SVH

Tuesday through Friday: Cooler and more unsettled weather can be
expected for next week as an upper level trough remains over the
region. The center of the upper low pivots across northwest
Washington through Wednesday but the speed it takes to push across
Inland Northwest is not clear. The GFS wants to hold a highly
amplitude trough over the Pacific NW through the week, meanwhile
the ECMWF shows the low kicking out quicker and leaving a baggy
trough behind. The difference in the sensible weather will be
coverage of showers. Initally, a frontal band will push across the
Cascades Tuesday afternoon ahead of the upper trough and then
stall over southeast Washington into north Idaho by Wednesday and
even into Thursday. Anticipate the best chance of post fronal
showers to be with the low center across the northern zones. West
to southwest winds will become gusty at times especially over the
afternoon and evening hours. Will continue to keep patchy smoke in
forecast through the week mainly near the source regions, although
anticipate more smoke dispersion with the winds and precipitation.
Expect daytime temperatures in the 70s, running below normal for
early September. /rfox.

.AVIATION...
18Z TAFS: Clouds have thickened across the region and radar shows
a band of very light showers moving east of the Cascades and
across eastern Washington. So far, only the higher terrain is
measuring the precipitation, and believe the TAF sites will just
see virga or vcsh through the afternoon. Cloud decks will be above
10k ft. Some smoke will be an issue in the KGEG-KCOE corridor
through midday, but as winds increase this should lift. Likewise
KPUW and KLWS will see some improvements this afternoon. Overnight
winds turn to the east and this should bring the smoke back into
these eastern TAF sites overnight with MVFR vsbys possible.
Gusty prefrontal winds will increase by 15z which should help
lift vsbys and dissperse the smoke. Light showers will move over
the Cascades before 18z. /rfox

.DISCUSSION...

...STRONG LOW PRESSURE SYSTEM TO DELIVER VERY STRONG WINDS AND
AREAS OF BLOWING DUST ON SATURDAY...

Tonight through Saturday: The highly advertised low pressure
system is beginning to take shape out at 130W/40N off of the
northern California coast. The surface low will continue to deep
ahead of a dynamic upper level shortwave trough of lower pressure.
The track will take the low up the coast line tonight. Additional
cyclogenesis will take place in the lee of the Cascades over
south-central WA early Saturday morning and track northward into
southern BC through the late morning hours. The associated cold
front will result in strong cold air advection that is expected to
result in good momentum mixing with much strong winds a loft
mixing down to the surface. The track of the low across the basin
and across the northern mountains of eastern WA will place the
strongest winds across this part of the region. With that said,
all areas will likely experience windy conditions. Most of the
rainfall with the front will occur across the east slopes of the
northern Cascade Mtns with only a chance expected in the post
frontal air mass across much of the rest of the region.

* Winds: Sustained winds of 25 to 35 mph with gusts to between 50
  to 60 mph will be possible with frontal passage from the late
  morning hours into the early afternoon. Gusts more into the 40
  to 50 mph range will be more likely later in the afternoon as
  the surface low pushes further away from the region. High
  profile vehicles will likely have a difficult time due to strong
  cross winds. Southerly winds will result in the strongest cross
  winds occurring along I-90 and Highway 2 across the basin.
  Strong cross winds can also be expected along Highway 95 and 195
  across the Palouse.

* Blowing Dust: The basin is not expected to receive much precip
  between now through Saturday afternoon. The strong winds through
  the day on Saturday is expected to present a potential dangerous
  blowing dust concern. The basin will be the greatest concern for
  blowing dust. Visibility may drop down to a 1/4 mile very
  quickly making for dangerous travel conditions. The blowing dust
  may stretch as far east as the Spokane/Coeur d`Alene Areas,

amounts of near a tenth of an inch with localized amounts near one
quarter of an inch will be possible across the eastern half of WA.
Thunderstorms will also be possible in the afternoon behind the

the ECMWF shows the low kicking out quicker and leaving a baggy
trough behind. The difference in the sensible weather will be
coverage of showers. Initally, a frontal band will push across the
Cascades Tuesday afternoon ahead of the upper trough and then
stall over southeast Washington into north Idaho by Wednesday and
even into Thursday. Anticipate the best chance of post fronal
showers to be with the low center across the northern zones. West
to southwest winds will become gusty at times especially over the
afternoon and evening hours. Will continue to keep patchy smoke in
forecast through the week mainly near the source regions, although
anticipate more smoke dispersion with the winds and precipitation.
Expect daytime temperatures in the 70s, running below normal for
early September. /rfox.

&&

.AVIATION...
18Z TAFS: Clouds have thickened across the region and radar shows
a band of very light showers moving east of the Cascades and
across eastern Washington. So far, only the higher terrain is
measuring the precipitation, and believe the TAF sites will just
see virga or vcsh through the afternoon. Cloud decks will be above
10k ft. Some smoke will be an issue in the KGEG-KCOE corridor
through midday, but as winds increase this should lift. Likewise
KPUW and KLWS will see some improvements this afternoon. Overnight
winds turn to the east and this should bring the smoke back into
these eastern TAF sites overnight with MVFR vsbys possible.
Gusty prefrontal winds will increase by 15z which should help
lift vsbys and dissperse the smoke. Light showers will move over
the Cascades before 18z. /rfox

Area Forecast Discussion
National Weather Service Spokane WA
1213 PM PDT FRI AUG 28 2015

.SYNOPSIS...
A cold front is approaching the area. Locally breezy conditions
are expected this afternoon with any showers expected to remain
mainly in the Cascades and northern mountains. This cold front
passage on Saturday will bring the potential for high winds. This
will create a situation for blowing dust with reduced visibility.
Some areas may also experience toppled trees and downed power
lines. A cooler and occasionally breezy regime with some shower
activity will persist through the next week.

&&

.DISCUSSION...
Updated the forecast to add some brief sprinkles across the
eastern zones as the radar continues to hold together. Only places
that have measured have been in the mountains, but light sprinkles
can be expected with the passing cloud deck. Expect winds to
increase through the afternoon which may help to disperse the
smoke in many spots. /rfox.

Area Forecast Discussion
National Weather Service Spokane WA
822 AM PDT FRI AUG 28 2015

.SYNOPSIS...
A cold front is approaching the area. Locally breezy conditions
are expected this afternoon with any showers expected to remain
mainly in the Cascades and northern mountains. This cold front
passage on Saturday will bring the potential for high winds. This
will create a situation for blowing dust with reduced visibility.
Some areas may also experience toppled trees and downed power
lines. A cooler and occasionally breezy regime with some shower
activity will persist through the next week.

&&

.DISCUSSION...
Updated the forecast to include the Columbia Basin, Palouse and
Spokane area in the RFW for Saturday due to the strong gusty winds
and lower RH with the cold front. This expands the current RFW
which covered much of the northern zones. For today, radar shows
light showers across the Cascades into the Okanogan Highlands. The
HRR shows this activity spreading slowly eastward today and could
see light showers into north Idaho mountains by afternoon. Most
valleys should stay on the dry side. Expect temperatures slightly
cooler and afternoon winds increasing helping to disperse the
smoke. /rfox

&&

.AVIATION...
12Z TAFS: Clouds will thicken and lower through the day ahead of a
cold front. Some occasional breezy conditions are possible in the
afternoon especially between MWH to GEG. A slight chance of
showers will pass by the Cascades into the Waterville Plateau and
into the northern mountains, perhaps in the vcnty of EAT but the
threat of anything measurable outside of the mountains is minimal.
Smoke will remain in the atmosphere and in some places potentially
renewed by the continued area wildfires. Look for some MVFR VIS
with smoke in the early morning hours around GEG to COE. Guidance
suggests a better threat of impacts to VIS from smoke around
PUW/LWS in the morning hours, with MVFR conditions, potentially
bordering on IFR as smoke from wildfires to the south becomes
trapped under the morning inversion. This threat is expected to
largely clear up after 17-19Z.
