Area Forecast Discussion
National Weather Service Spokane WA
506 PM PDT MON MAR 30 2015

.SYNOPSIS...
The Inland Northwest has enjoyed the last day of well above
average temperatures before a vigorous cold front arrives during
the early morning hours on Tuesday. The front will bring gusty
west winds and showers on Tuesday. Wednesday through the weekend
will be seasonably cool and unsettled with a chance for showers.

&&

.DISCUSSION...
Update: After evaluating the 18z GFS/NAM model runs and the past
3 HRRR runs...a few edits were made to the overnight forecast. A
slight chance of thunderstorms was added from the Blue Mountains
to the Central Panhandle Mountains including the Palouse and
Lewiston area. Previous discussions have mentioned this
possibility but confidence has increased a bit more to mention in
the forecast. A slight chance of rain showers was also expanded
westward a bit to include the western Palouse, and Spokane/Coeur
D`Alene area. There is general model agreement that a band of
elevated instability in the 700-500mb layer will develop over
Southeast Washington late this evening before tracking northeast
into the Central Panhandle Mountains overnight. Most unstable CAPE
values increase to 100-300 J/KG with no convective inhibition
above 700mb. This combined with a Theta-e ridge axis over the
area, and increased forcing may trigger a few thunderstorms. The
HRRR shows this activity could develop and track a bit further
west to include the Upper Columbia Basin and Spokane area.
Although thunder is less likely in these areas with the best mid
level instability south and east of these areas. JW

&&

.AVIATION...
00Z TAFS: A cold front will arrive Tuesday morning. Between 06z-
12z, a narrow corridor of elevated instability over NE Oregon, SE
Wa, then north into the Spokane region, increasing the threat of
scattered high- based showers. Ceilings should remain VFR, but
drop to around 6-9k ft agl. A couple nocturnal lightning strikes
are not out of the question. Expect to see a dramatic increase in
west winds beginning around 15-18z...with gusts as high as 40 mph
possible by late morning.  JW

.SYNOPSIS...
The Inland Northwest has enjoyed the last day of well above
average temperatures before a vigorous cold front arrives during
the early morning hours on Tuesday. The front will bring gusty
west winds and showers on Tuesday. Wednesday through the weekend
will be seasonably cool and unsettled with a chance for showers.

&&

.DISCUSSION...
Tonight: With the approach of the upper trough and cold front
today, we`ve been watching a surge of mid-level moisture and
instability moving NE through Oregon. Though there is no pcpn
falling upstream (Oregon) with this elevated moisture, we still
expect large-scale forcing for ascent to release this instability
and begin to produce rain showers late tonight spreading from NE
Oregon, through the Palouse and into the Cntrl Id Panhandle.
Spokane and Coeur D`alene are on the edge of this pcpn, so don`t
be surprised if you see a few rain showers for the morning
commute. Thunder is not expected, but given the degree of
convective instability in the 700-500mb layer it`s possible.bz

Tuesday through Wednesday: A cold front is expected to pass
through the region on Tuesday. As the front begins to press
through the Cascades Tuesday morning, prefrontal showers are
possible in the Southeastern Washington and Lower Idaho Panhandle
regions. By Tuesday afternoon, the front is over the Idaho
Panhandle and bring widespread rain showers to the region. The
Cape values and lapse rates indicate a possible thunderstorm
development in Eastern Washington and Idaho Panhandle from the
afternoon into the early Tuesday evening. These storms are
expected to bring some lightning strikes and be short lived. By
Tuesday night the treat of thunder is gone but winds begin to pick
up in the region. Winds are expected be breezy throughout time of
Tuesday night and Wednesday with sustained around 20-25 MPH and
gusts up to 40 MPH. Snow levels will drop behind the front and
spring like snow event is possible for the mountains. Some of the
higher terrain could see an inch or two of snow but accumulation
is expected to be minimal. For Wednesday, widespread rain showers
is expected with possible graupel and small hail during the
afternoon as the atmosphere destabilizes with upper level cold
air and diurnal heating. By wednesday night, the atmosphere
stabilizes, the wide spread showers start to decrease, and the
winds decrease as the gradient in the region weakens. /JDC

Thursday through Monday: Expect more typical spring like weather
for the Inland Northwest for the latter half of the week and
through the weekend. The ridge of high pressure will start off
along the coast for Thursday, allowing a moist northwest flow with
an embedded impulse to clip northeast Washington and the Idaho
panhandle by Thursday afternoon. Anticipate showers to increase
during the afternoon and evening hours. Surface based instability
looks marginal but could see more graupel showers and a possible
lightning strike. This impulse exits to the east Thursday night,
while the upper ridge translates into the region. Light winds and
increased stability may lead to patchy valley fog late that night
and into Friday morning. The ridge flattens out during the day on
Friday with increasing clouds as the first of many shortwaves roll
across the region. The pattern becomes quite progressive and
unstable. This first front arrives late Friday with rain and
mountain snow, mainly near the Canadian border, then quickly
pushing south and east Friday evening with showers persisting in
extreme eastern Washington and north Idaho into the night. An
upper level low descends south from the Gulf of Alaska and keeps
the unsettled pattern through the weekend with a moist, unstable
southwest flow across the region. Convection will increase during
the afternoon and evening hours, as snow levels range from 3-4k ft
with a continued threat of graupel and a possible lightning
strike. By Sunday, the medium range models diverge slightly on the
track of the upper level low. The GFS and Canadian show the upper
low weakening and opening up, allowing the feature to swing
inland. The ECWMF keeps the closed circulation off the coast and
sinks it southward. Each will keep the sensible weather showery
especially in the mountains. Temperatures will hover near seasonal
normals. /rfox.

.SYNOPSIS...
The Inland Northwest has enjoyed the last day of well above
average temperatures before a vigorous cold front arrives during
the early morning hours on Tuesday. The front will bring gusty
west winds and showers on Tuesday. Wednesday through the weekend
will be seasonably cool and unsettled with a chance for showers.

&&

.DISCUSSION...
Tonight: With the approach of the upper trough and cold front
today, we`ve been watching a surge of mid-level moisture and
instability moving NE through Oregon. Though there is no pcpn
falling upstream (Oregon) with this elevated moisture, we still
expect large-scale forcing for ascent to release this instability
and begin to produce rain showers late tonight spreading from NE
Oregon, through the Palouse and into the Cntrl Id Panhandle.
Spokane and Coeur D`alene are on the edge of this pcpn, so don`t
be surprised if you see a few rain showers for the morning
commute. Thunder is not expected, but given the degree of
convective instability in the 700-500mb layer it`s possible.bz

Tuesday through Wednesday: A cold front is expected to pass
through the region on Tuesday. As the front begins to press
through the Cascades Tuesday morning, prefrontal showers are
possible in the Southeastern Washington and Lower Idaho Panhandle
regions. By Tuesday afternoon, the front is over the Idaho
Panhandle and bring widespread rain showers to the region. The
Cape values and lapse rates indicate a possible thunderstorm
development in Eastern Washington and Idaho Panhandle from the
afternoon into the early Tuesday evening. These storms are
expected to bring some lightning strikes and be short lived. By
Tuesday night the treat of thunder is gone but winds begin to pick
up in the region. Winds are expected be breezy throughout time of
Tuesday night and Wednesday with sustained around 20-25 MPH and
gusts up to 40 MPH. Snow levels will drop behind the front and
spring like snow event is possible for the mountains. Some of the
higher terrain could see an inch or two of snow but accumulation
is expected to be minimal. For Wednesday, widespread rain showers
is expected with possible graupel and small hail during the
afternoon as the atmosphere destabilizes with upper level cold
air and diurnal heating. By wednesday night, the atmosphere
stabilizes, the wide spread showers start to decrease, and the
winds decrease as the gradient in the region weakens. /JDC

Thursday through Monday: Expect more typical spring like weather
for the Inland Northwest for the latter half of the week and
through the weekend. The ridge of high pressure will start off
along the coast for Thursday, allowing a moist northwest flow with
an embedded impulse to clip northeast Washington and the Idaho
panhandle by Thursday afternoon. Anticipate showers to increase
during the afternoon and evening hours. Surface based instability
looks marginal but could see more graupel showers and a possible
lightning strike. This impulse exits to the east Thursday night,
while the upper ridge translates into the region. Light winds and
increased stability may lead to patchy valley fog late that night
and into Friday morning. The ridge flattens out during the day on
Friday with increasing clouds as the first of many shortwaves roll
across the region. The pattern becomes quite progressive and
unstable. This first front arrives late Friday with rain and
mountain snow, mainly near the Canadian border, then quickly
pushing south and east Friday evening with showers persisting in
extreme eastern Washington and north Idaho into the night. An
upper level low descends south from the Gulf of Alaska and keeps
the unsettled pattern through the weekend with a moist, unstable
southwest flow across the region. Convection will increase during
the afternoon and evening hours, as snow levels range from 3-4k ft
with a continued threat of graupel and a possible lightning
strike. By Sunday, the medium range models diverge slightly on the
track of the upper level low. The GFS and Canadian show the upper
low weakening and opening up, allowing the feature to swing
inland. The ECWMF keeps the closed circulation off the coast and
sinks it southward. Each will keep the sensible weather showery
especially in the mountains. Temperatures will hover near seasonal
normals. /rfox.

&&

.AVIATION...
18Z TAFS: A cold front will arrive Tuesday morning. Between 06z-
12z, a narrow corridor of elevated instability over NE Oregon,
SE Wa, then north into the Spokane region, increasing the threat
of scattered high- based showers. Ceilings should remain VFR, but
drop to around 6-9k ft agl. A couple nocturnal lightning strikes
are not out of the question. Expect to see a dramatic increase in
west winds beginning around 15-18z...with gusts as high as 40 mph
possible by late morning.bz

.SYNOPSIS...
The Inland Northwest will enjoy one last day of well above
average temperatures before a vigorous cold front arrives during
the early morning hours on Tuesday. The front will bring gusty
west winds and showers on Tuesday. Wednesday through the weekend
will be seasonably cool and unsettled with a chance for showers.

&&

.DISCUSSION...
Rest of Today: Rising heights aloft and a surge of warm air will
work its way into Ern Wa on southerly winds to produce a dry and
warm fcst under partly to mostly mostly sunny skies. Sfc obs show
that the majority of any clouds will only be cirrus...helping to
produce high temps around 10-15F above normal. Record high temps
are not expected. The valley fog in N Idaho should be gone by late
morning.

For tonight and Tues-Wed we`ll be working on fine-tuning the
chance for showers late tonight over SE Wa and the Cntrl Idaho
Panhandle...followed by very gusty winds, rain and thunder for
Tue. Winds will decrease Wed. bz

&&

.AVIATION...
12Z TAFS: The Inland Northwest will be in the warm sector today
and tonight ahead of a cold front expected to arrive Tuesday
morning. Scattered to broken 15 to 20 thousand foot clouds are
expected from 12z-06z region-wide. Between 06z-12z, a narrow
corridor of elevated instability over northeast Oregon, southeast
Washington, and the southern Idaho Panhandle will have the
potential to produce scattered high-based showers. The Lewiston,
Pullman, and Coeur D`Alene TAFs have the possibility of showers
in a PROB30 group. A couple nocturnal lightning strikes isn`t out
of the question in the vicinity of these airports. /GKoch

.SYNOPSIS...
The Inland Northwest will enjoy one last day of well above

the early morning hours on Tuesday. The front will bring gusty
west winds and showers on Tuesday. Wednesday through the weekend
will be seasonably cool and unsettled with a chance for showers.

&&

.DISCUSSION...

...WIND GUSTS TO 40 MPH EXPECTED TUESDAY ACROSS THE COLUMBIA
BASIN...PALOUSE...WEST PLAINS...

Today: Our flat upper level ridge will amplify a bit today ahead
of an approaching cold front. The subtle increase in deep
southerly flow will draw unseasonably mild temperatures into the
region. With 850mb temperatures ranging from 8-11C across the
Inland Northwest, we are expecting afternoon highs to reach the
60s. Warm spots along the Snake and Columbia Rivers in southeast
and south central Washington will likely eclipse 70. These
readings are a good 10 to 15 degrees above average.

Tuesday: Big changes will arrive by the early morning hours on
Tuesday with the arrival of a fast moving cold front. Gusty west
winds, falling snow levels, and the potential for widely scattered
thunderstorms will be associated with this vigorous early spring
storm system.

* Winds: Compared to model runs 24 hours ago, the wind speeds have
  trended down a bit. The GFS continues to prog stronger 850mb
  winds than the NAM...35-40kts compared to 30-35kts. Local
  verification studies suggest that GFS MOS guidance performs
  better in post cold front wind events, and the GFS guidance
  looks pretty reasonable forecasting sustained winds of 20 to 25
  mph Tuesday afternoon with gusts to 40 mph. A tight pressure
  gradient combined with steep lapse rates to 700mb during the
  afternoon hours suggest very efficient mixing of downward
  momentum. Add the potential for downdrafts from convective
  showers over the Idaho Panhandle and eastern third of
  Washington, it looks like gusts up to 40 mph will be a pretty
  good bet from the Waterville Plateau to Spokane to Pullman.

* Precipitation: This frontal system will not bring as much deep
  layer moisture as last Saturday`s front. Much of the
  precipitation with this system will be generated by convection.
  Strong cold advection is advertised with 500mb temperatures of
  -32C arriving Tuesday afternoon/evening. Look for snow levels to
  plunge to 3000 feet over the Cascades by Tuesday afternoon, and
  to 3500 feet over the Idaho Panhandle by Tuesday evening. The
  mountains of the Idaho Panhandle will have a good shot of a
  couple inches of snow by Tuesday night. Travel probably won`t be
  impacted much in the Idaho Panhandle, but there will be a chance
  that a Puget Sound Convergence Zone could become established
  near Stevens Pass Tuesday afternoon/night. Motorists on Highway
  2 could experience some slick driving conditions Tuesday night.

* Thunderstorm Potential: Prefrontal elevated instability
  continues to be advertised by the NAM and ECMWF late Monday
  night into Tuesday morning over southeast Washington into the
  central/southern Panhandle. A handful of pre-cold front strikes
  around Lewiston, Pullman, and St Maries isn`t out of the
  question overnight. Then Tuesday afternoon, strong upper level
  cooling will steepen lapse rates and yield a couple hundred
  joules/kg of surface based CAPE over northeast Washington and
  the Idaho Panhandle. The deep layer cooling may actually push
  LCLs (Lifting Condensation Levels) too cold Tuesday
  afternoon/evening for thunderstorms. LCLs colder than -5C often
  times don`t produce much lightning and yield graupel showers.
  With that in mind, only isolated thunder is in the forecast from
  Colville to Sandpoint to Spokane to Kellogg Tuesday afternoon.
  /GKoch

Wednesday through Thursday: A cold upper level trough of lower
pressure will be over the region. A -33 C cold pool aloft at 500
mbs will result in a destabilizing atmosphere during the
afternoon. All of the region will see a chance for showers on
Wednesday. The cold pool will then focus showers mainly across
extreme eastern WA and in the ID Panhandle on Thursday. There is a
high probability for soft hail or graupel showers. Temperatures
are expected to feel more like what is typical for March and
should be slightly below normal. Expect high temperatures in the
upper 40s to mid 50s with lows dipping down into the mid 20s and
mid 30s across most locations.

Thursday night through Sunday: Models are in decent agreement with
another cold upper level low pressure system dropping down out of
the Gulf of Alaska. There are some discrepancies with where this
trough will dig. The ECMWF model has the upper trough digging a
bit more offshore, whereas the GFS model digs the trough further
east more over the Northwest. The ECMWF depiction would result in
a slight bump up in temperatures with southerly flow into the
region. The GFS depiction would keep temperatures at or slightly
below normal through this period. Either way it looks as if this
upper low will swing in over the region at some point. This will
keep the weather unsettled with precip chances at least above
climatology. /SVH

.SYNOPSIS...
The Inland Northwest will enjoy one last day of well above
average temperatures before a vigorous cold front arrives during
the early morning hours on Tuesday. The front will bring gusty
west winds and showers on Tuesday. Wednesday through the weekend
will be seasonably cool and unsettled with a chance for showers.

&&

.DISCUSSION...

...WIND GUSTS TO 40 MPH EXPECTED TUESDAY ACROSS THE COLUMBIA
BASIN...PALOUSE...WEST PLAINS...

Today: Our flat upper level ridge will amplify a bit today ahead
of an approaching cold front. The subtle increase in deep
southerly flow will draw unseasonably mild temperatures into the
region. With 850mb temperatures ranging from 8-11C across the
Inland Northwest, we are expecting afternoon highs to reach the
60s. Warm spots along the Snake and Columbia Rivers in southeast
and south central Washington will likely eclipse 70. These
readings are a good 10 to 15 degrees above average.

Tuesday: Big changes will arrive by the early morning hours on
Tuesday with the arrival of a fast moving cold front. Gusty west
winds, falling snow levels, and the potential for widely scattered
thunderstorms will be associated with this vigorous early spring
storm system.

* Winds: Compared to model runs 24 hours ago, the wind speeds have
  trended down a bit. The GFS continues to prog stronger 850mb
  winds than the NAM...35-40kts compared to 30-35kts. Local
  verification studies suggest that GFS MOS guidance performs
  better in post cold front wind events, and the GFS guidance
  looks pretty reasonable forecasting sustained winds of 20 to 25
  mph Tuesday afternoon with gusts to 40 mph. A tight pressure
  gradient combined with steep lapse rates to 700mb during the
  afternoon hours suggest very efficient mixing of downward
  momentum. Add the potential for downdrafts from convective
  showers over the Idaho Panhandle and eastern third of
  Washington, it looks like gusts up to 40 mph will be a pretty
  good bet from the Waterville Plateau to Spokane to Pullman.

* Precipitation: This frontal system will not bring as much deep
  layer moisture as last Saturday`s front. Much of the
  precipitation with this system will be generated by convection.
  Strong cold advection is advertised with 500mb temperatures of
  -32C arriving Tuesday afternoon/evening. Look for snow levels to
  plunge to 3000 feet over the Cascades by Tuesday afternoon, and
  to 3500 feet over the Idaho Panhandle by Tuesday evening. The
  mountains of the Idaho Panhandle will have a good shot of a
  couple inches of snow by Tuesday night. Travel probably won`t be
  impacted much in the Idaho Panhandle, but there will be a chance
  that a Puget Sound Convergence Zone could become established
  near Stevens Pass Tuesday afternoon/night. Motorists on Highway
  2 could experience some slick driving conditions Tuesday night.

* Thunderstorm Potential: Prefrontal elevated instability
  continues to be advertised by the NAM and ECMWF late Monday
  night into Tuesday morning over southeast Washington into the
  central/southern Panhandle. A handful of pre-cold front strikes
  around Lewiston, Pullman, and St Maries isn`t out of the
  question overnight. Then Tuesday afternoon, strong upper level
  cooling will steepen lapse rates and yield a couple hundred
  joules/kg of surface based CAPE over northeast Washington and
  the Idaho Panhandle. The deep layer cooling may actually push
  LCLs (Lifting Condensation Levels) too cold Tuesday
  afternoon/evening for thunderstorms. LCLs colder than -5C often
  times don`t produce much lightning and yield graupel showers.
  With that in mind, only isolated thunder is in the forecast from
  Colville to Sandpoint to Spokane to Kellogg Tuesday afternoon.
  /GKoch

Wednesday through Thursday: A cold upper level trough of lower
pressure will be over the region. A -33 C cold pool aloft at 500
mbs will result in a destabilizing atmosphere during the
afternoon. All of the region will see a chance for showers on
Wednesday. The cold pool will then focus showers mainly across
extreme eastern WA and in the ID Panhandle on Thursday. There is a
high probability for soft hail or graupel showers. Temperatures
are expected to feel more like what is typical for March and
should be slightly below normal. Expect high temperatures in the
upper 40s to mid 50s with lows dipping down into the mid 20s and
mid 30s across most locations.

Thursday night through Sunday: Models are in decent agreement with
another cold upper level low pressure system dropping down out of
the Gulf of Alaska. There are some discrepancies with where this
trough will dig. The ECMWF model has the upper trough digging a
bit more offshore, whereas the GFS model digs the trough further
east more over the Northwest. The ECMWF depiction would result in
a slight bump up in temperatures with southerly flow into the
region. The GFS depiction would keep temperatures at or slightly
below normal through this period. Either way it looks as if this
upper low will swing in over the region at some point. This will
keep the weather unsettled with precip chances at least above
climatology. /SVH

&&

.AVIATION...
12Z TAFS: The Inland Northwest will be in the warm sector today
and tonight ahead of a cold front expected to arrive Tuesday
morning. Scattered to broken 15 to 20 thousand foot clouds are
expected from 12z-06z region-wide. Between 06z-12z, a narrow
corridor of elevated instability over northeast Oregon, southeast
Washington, and the southern Idaho Panhandle will have the
potential to produce scattered high-based showers. The Lewiston,
Pullman, and Coeur D`Alene TAFs have the possibility of showers
in a PROB30 group. A couple nocturnal lightning strikes isn`t out
of the question in the vicinity of these airports. /GKoch

mid 30s across most locations.

Thursday night through Sunday: Models are in decent agreement with
another cold upper level low pressure system dropping down out of
the Gulf of Alaska. There are some discrepancies with where this
trough will dig. The ECMWF model has the upper trough digging a
bit more offshore, whereas the GFS model digs the trough further
east more over the Northwest. The ECMWF depiction would result in
a slight bump up in temperatures with southerly flow into the
region. The GFS depiction would keep temperatures at or slightly
below normal through this period. Either way it looks as if this
upper low will swing in over the region at some point. This will
keep the weather unsettled with precip chances at least above
climatology. /SVH

258 AM PDT MON MAR 30 2015

.SYNOPSIS...
The Inland Northwest will enjoy one last day of well above
average temperatures before a vigorous cold front arrives during
the early morning hours on Tuesday. The front will bring gusty
west winds and showers on Tuesday. Wednesday through the weekend
will be seasonably cool and unsettled with a chance for showers.

&&

.DISCUSSION...

...WIND GUSTS TO 40 MPH EXPECTED TUESDAY ACROSS THE COLUMBIA
BASIN...PALOUSE...WEST PLAINS...

Today: Our flat upper level ridge will amplify a bit today ahead
of an approaching cold front. The subtle increase in deep
southerly flow will draw unseasonably mild temperatures into the
region. With 850mb temperatures ranging from 8-11C across the
Inland Northwest, we are expecting afternoon highs to reach the
60s. Warm spots along the Snake and Columbia Rivers in southeast
and south central Washington will likely eclipse 70. These
readings are a good 10 to 15 degrees above average.

Tuesday: Big changes will arrive by the early morning hours on
Tuesday with the arrival of a fast moving cold front. Gusty west
winds, falling snow levels, and the potential for widely scattered
thunderstorms will be associated with this vigorous early spring
storm system.

* Winds: Compared to model runs 24 hours ago, the wind speeds have
  trended down a bit. The GFS continues to prog stronger 850mb
  winds than the NAM...35-40kts COMPARED to 30-35kts. Local
  verification studies suggest that GFS MOS guidance performs
  better in post cold front wind events, and the GFS guidance
  looks pretty reasonable forecasting sustained winds of 20 to 25
  mph Tuesday afternoon with gusts to 40 mph. A tight pressure
  gradient combined with steep lapse rates to 700mb during the
  afternoon hours suggest very efficient mixing of downward
  momentum. Add the potential for downdrafts from convective
  showers over the Idaho Panhandle and eastern third of
  Washington, it looks like gusts up to 40 mph will be a pretty
  good bet from the Waterville Plateau to Spokane to Pullman.

* Precipitation: This frontal system will not bring as much deep
  layer moisture as last Saturday`s front. Much of the
  precipitation with this system will be generated by convection.
  Strong cold advection is advertised with 500mb temperatures of
  -32C arriving Tuesday afternoon/evening. Look for snow levels to
  plunge to 3000 feet over the Cascades by Tuesday afternoon, and
  to 3500 feet over the Idaho Panhandle by Tuesday evening. The
  mountains of the Idaho Panhandle will have a good shot of a
  couple inches of snow by Tuesday night. Travel probably won`t be
  impacted much in the Idaho Panhandle, but there will be a chance
  that a Puget Sound Convergence Zone could become established
  near Stevens Pass Tuesday afternoon/night. Motorists on Highway
  2 could experience some slick driving conditions Tuesday night.

* Thunderstorm Potential: Prefrontal elevated instability
  continues to be advertised by the NAM late Monday night into
  Tuesday morning over southeast Washington into the
  central/southern Panhandle. A handful of pre-cold front strikes
  around Lewiston, Pullman, and St Maries isn`t out of the
  question overnight. Then Tuesday afternoon, strong upper level
  cooling will steepen lapse rates and yield a couple hundred
  joules/kg of surface based CAPE over northeast Washington and
  the Idaho Panhandle. The deep layer cooling may actually push
  LCLs (Lifting Condensation Levels) too cold Tuesday
  afternoon/evening for thunderstorms. LCLs colder than -5C often
  times don`t produce much lightning and yield graupel showers.
  With that in mind, only isolated thunder is in the forecast from
  Colville to Sandpoint to Spokane to Kellogg Tuesday afternoon.
  /GKoch

Wednesday through Thursday: A cold upper level trough of lower
pressure will be over the region. A -33 C cold pool aloft at 500
mbs will result in a destabilizing atmosphere during the
afternoon. All of the region will see a chance for showers on
Wednesday. The cold pool will then focus showers mainly across
extreme eastern WA and in the ID Panhandle on Thursday. There is a
high probability for soft hail or graupel showers. Temperatures
are expected to feel more like what is typical for March and
should be slightly below normal. Expect high temperatures in the
upper 40s to mid 50s with lows dipping down into the mid 20s and
mid 30s across most locations.

Thursday night through Sunday: Models are in decent agreement with
another cold upper level low pressure system dropping down out of
the Gulf of Alaska. There are some discrepancies with where this
trough will dig. The ECMWF model has the upper trough digging a
bit more offshore, whereas the GFS model digs the trough further
east more over the Northwest. The ECMWF depiction would result in
a slight bump up in temperatures with southerly flow into the
region. The GFS depiction would keep temperatures at or slightly
below normal through this period. Either way it looks as if this
upper low will swing in over the region at some point. This will
keep the weather unsettled with precip chances at least above

.SYNOPSIS...
The storm track will retreat north into Canada through Monday
producing mild weather for the Inland Northwest. A vigorous spring
storm system will bring another chance for showers and strong
winds to our region on Tuesday. Wind gusts exceeding 40 mph will
be possible Tuesday afternoon and evening. Wednesday through next
weekend will be showery with temperatures near normal.

&&

.DISCUSSION...

Tonight and Monday: Another in a series of quick-moving warm
fronts will lift NE across Ern Wa overnight, then into BC Monday
morning. Though there`s fairly deep isentropic ascent over this
boundary, the column is rather dry which may explain the lack of
pcpn generated by model guidance overnight. Again, only light
amnts of rain and high mountain snow is expected...and limited to
areas close the BC border. Once this waves moves into BC, rising
heights aloft and a surge of warm air works its way into Ern Wa on
southerly winds to produce a dry and warmer fcst under mostly sunny
skies. High temps will be around 10F above normal. bz

Monday Night through Wednesday: Beginning late Monday, early
Tuesday, the ridge begins to breakdown as a cold front begins to
press into the region. This is expected to bring rain showers for
most populated locations in the region. Snow levels will be above
4500 feet. A combination of the cooler air aloft, orographic lift,
and diurnal surface heating could produce an isolated thunderstorm
in Eastern Washington and Idaho Panhandle region with the best
chances being along the Canadian Border. The winds behind the
front will be strong. Sustained winds of 20 to 30 MPH and gusts
near 40 MPH are expected in the Columbia Basin. Temperatures are
expected to be near the season normals for this time of year. The
winds will begin draw down on Wednesday as the gradient loosens
across the region. Lingering mountains will drop some rain, snow
mix as the snow levels drop to around 2500 feet behind the cold
front. Any accumulations will be small and short lived. /JDC

Wednesday night through Sunday...A cold upper trough will start to
migrate east of the forecast area Wednesday night. Instability
showers will diminish overnight. If there is adequate clearing
overnight, Thursday morning temperatures will drop into the 20s
for the northern valleys. Lingering upslope showers will be
invigorated by steepening lapse rates during daytime heating
Thursday. The convective nature of showers will allow snow to
reach some valley floors but any accumulating snow will quickly
melt once showers move on. The trough axis will swing east into
Montana and temporary ridging will set up Thursday night into
Friday but models disagree on the amplitude and staying power of
the ridge. A weak frontal system will affect the forecast area
late in the workweek or early in the weekend but the most
significant weather feature will be a cold upper trough that
descends south from the Gulf of Alaska. The precise track of the
low pressure center will determine just how cold and unsettled it
will be for the weekend into the start of next week. The best bet
for precipitation will be across the northern mountains during
peak daytime heating as convective showers blossom in the unstable
conditions. Temperatures will continue to trend just on the cool
side of climatology. Again, any clearing overnight will make for a
chilly start in the mornings. /Kelch

areas close the BC border. Once this waves moves into BC, rising
heights aloft and a surge of warm air works its way into Ern Wa on
southerly winds to produce a dry and warmer fcst under mostly sunny
skies. High temps will be around 10F above normal. bz

Monday Night through Wednesday: Beginning late Monday, early
Tuesday, the ridge begins to breakdown as a cold front begins to
press into the region. This is expected to bring rain showers for
most populated locations in the region. Snow levels will be above
4500 feet. A combination of the cooler air aloft, orographic lift,
and diurnal surface heating could produce an isolated thunderstorm
in Eastern Washington and Idaho Panhandle region with the best
chances being along the Canadian Border. The winds behind the
front will be strong. Sustained winds of 20 to 30 MPH and gusts
near 40 MPH are expected in the Columbia Basin. Temperatures are
expected to be near the season normals for this time of year. The
winds will begin draw down on Wednesday as the gradient loosens
across the region. Lingering mountains will drop some rain, snow
mix as the snow levels drop to around 2500 feet behind the cold
front. Any accumulations will be small and short lived. /JDC

Wednesday night through Sunday...A cold upper trough will start to
migrate east of the forecast area Wednesday night. Instability
showers will diminish overnight. If there is adequate clearing
overnight, Thursday morning temperatures will drop into the 20s
for the northern valleys. Lingering upslope showers will be
invigorated by steepening lapse rates during daytime heating
Thursday. The convective nature of showers will allow snow to
reach some valley floors but any accumulating snow will quickly
melt once showers move on. The trough axis will swing east into
Montana and temporary ridging will set up Thursday night into
Friday but models disagree on the amplitude and staying power of
the ridge. A weak frontal system will affect the forecast area
late in the workweek or early in the weekend but the most
significant weather feature will be a cold upper trough that
descends south from the Gulf of Alaska. The precise track of the
low pressure center will determine just how cold and unsettled it
will be for the weekend into the start of next week. The best bet
for precipitation will be across the northern mountains during
peak daytime heating as convective showers blossom in the unstable
conditions. Temperatures will continue to trend just on the cool
side of climatology. Again, any clearing overnight will make for a
chilly start in the mornings. /Kelch

for the northern valleys. Lingering upslope showers will be
invigorated by steepening lapse rates during daytime heating
Thursday. The convective nature of showers will allow snow to
reach some valley floors but any accumulating snow will quickly
melt once showers move on. The trough axis will swing east into
Montana and temporary ridging will set up Thursday night into
Friday but models disagree on the amplitude and staying power of
the ridge. A weak frontal system will affect the forecast area
late in the workweek or early in the weekend but the most
significant weather feature will be a cold upper trough that
descends south from the Gulf of Alaska. The precise track of the
low pressure center will determine just how cold and unsettled it
will be for the weekend into the start of next week. The best bet
for precipitation will be across the northern mountains during
peak daytime heating as convective showers blossom in the unstable
conditions. Temperatures will continue to trend just on the cool
side of climatology. Again, any clearing overnight will make for a
chilly start in the mornings. /Kelch

.AVIATION...
18Z TAFS: A couple of weak upper level disturbances will over-
top our flat upper level ridge today and tonight. Bands of mid and
high level clouds with ceilings at or above 8-10k ft agl are
expected. Some light rain/high elevation snow will be possible
over the mountains along the Canadian border, but is not expected
to impact airports in the region.

.SYNOPSIS...
The storm track will retreat north into Canada today and Monday
producing mild weather for the Inland Northwest. A vigorous
spring storm system will bring another chance for showers and
strong winds to our region on Tuesday. Wind gusts exceeding 40 mph
will be possible Tuesday afternoon and evening. Wednesday through
next weekend looks to be showery with temperatures near normal.

&&

.DISCUSSION...
Rest of today: A quick-moving warm frontal boundary across far
Ern Wa and the Idaho Panhandle attm will move into Montana by
midday, allowing for skies to become at least partly sunny across
the Upper Columbia Basin...including locations near the E slopes
of the Cascades. Sfc obs and the KOTX VWP show ceilings of around
8000-1000ft with the weak isentropic ascent tied to the warm
front, so there may be brief very light stratiform rain this
morning for the valleys of NE Wa and the Idaho Panhandle. The
mountains will have a higher chance, but again only light amnts
are expected. Snow levels will remain above 4500-5000 ft msl.bz

.SYNOPSIS...
The storm track will retreat north into Canada today and Monday
producing mild weather for the Inland Northwest. A vigorous
spring storm system will bring another chance for showers and
strong winds to our region on Tuesday. Wind gusts exceeding 40 mph
will be possible Tuesday afternoon and evening. Wednesday through
next weekend looks to be showery with temperatures near normal.

.DISCUSSION...

...STRONG COLD FRONT TO DELIVER WINDY CONDITIONS ACROSS THE INLAND
NORTHWEST TUESDAY AFTERNOON...

Today through Monday: A flat upper level ridge at 500mb will
reside over the Pacific Northwest today into Monday. Vancouver
Island and the southern coast of British Columbia will experience
periods of rain during the next couple of days as a plume of
subtropical moisture is directed into southwestern Canada. Small
chances for light rain will extend as far south as the mountains
of far north central and northeast Washington today and tonight,
but the majority of our forecast area should be dry under bands of
mid and high level clouds. There will be much less wind today and
Monday with the typical afternoon increase in southwest winds,
generally in the 10 to 15 mph range. /GKoch

Tuesday: A vigorous cold front will seep across the region
Tuesday morning with the upper level trough of lower pressure
moving in for the afternoon. Models are in good agreement with a
deepening surface low scooting across southern BC into southern
Alberta through the day on Tuesday. Models all show the surface
low bottoming out at around 992 mbs along the eastern Divide in
southern Alberta by the afternoon hours. This will set up a
strong surface gradient, which will coincide with a favorable
time of day for mixing potential. The surface gradient looks to be
a little bit stronger compared to this past Saturday`s wind event
and there were spotty locations with sustained wind speeds of
30-35 mph. This front will have the potential for similar wind
speeds, but on a more widespread basis. This will include anywhere
from the Wenatchee Area, across the basin and over into the
exposed areas of the southern to central ID Panhandle. Winds up at
850 mbs look to peak at around 35-40 kts, which would translate to
a gust potential somewhere in the range of up to 40-45 mph. There
is a good possibility that a Wind Advisory will be needed for
Tuesday afternoon, but is still a bit early for a highlight at
this time this far out in the forecast period.

A 500 mb cold pool aloft will also result in the atmosphere
destabilizing through the afternoon. Showers will develop out
ahead of the cold front through the morning on Tuesday with more
showers likely developing in the conditionally unstable atmosphere
through the afternoon hours. Best chances for showers are expected
across the eastern half of the forecast area. There will also be a
chance for thunderstorms in the afternoon across the Okanogan
Highlands over into the Northern Panhandle.

Tuesday night through Sunday: A cold upper level trough of lower
pressure will hang around through Thursday. The cold front on
Tuesday will usher in colder temperatures with temperatures
closer to or slightly below normal. The cold upper level trough
will result in afternoon showers with the potential for some soft
hail or graupel. Shortwave ridging of higher pressure moves in
Thursday night, but another upper level trough of lower pressure
looks to drop down into the region for Friday through the
weekend. This will keep temperatures slightly below normal with
more convective showers expected, especially during the afternoon.

12Z TAFS: A couple of weak upper level disturbances will over-top

over the mountains along the Canadian border, but is not expected
to impact airports in the region. /GKoch

.SYNOPSIS...
The storm track will retreat north into Canada today and Monday
producing mild weather to the Inland Northwest. A vigorous spring
storm system will bring another chance for showers and strong
winds to our region on Tuesday. Wind gusts exceeding 40 mph will
be possible Tuesday afternoon and evening. Wednesday through next
weekend looks to be showery with temperatures near normal.

.DISCUSSION...

...STRONG COLD FRONT TO DELIVER WINDY CONDITIONS ACROSS THE INLAND
NORTHWEST TUESDAY AFTERNOON...

Today through Monday: A flat upper level ridge at 500mb will
reside over the Pacific Northwest today into Monday. Vancouver
Island and the southern coast of British Columbia will experience
periods of rain during the next couple of days as a plume of
subtropical moisture is directed into southwestern Canada. Small
chances for light rain will extend as far south as the mountains
of far north central and northeast Washington today and tonight,
but the majority of our forecast area should be dry under bands of
mid and high level clouds. There will be much less wind today and
Monday with the typical afternoon increase in southwest winds,
generally in the 10 to 15 mph range. /GKoch

Tuesday: A vigorous cold front will seep across the region
Tuesday morning with the upper level trough of lower pressure
moving in for the afternoon. Models are in good agreement with a
deepening surface low scooting across southern BC into southern
Alberta through the day on Tuesday. Models all show the surface
low bottoming out at around 992 mbs along the eastern Divide in
southern Alberta by the afternoon hours. This will set up a
strong surface gradient, which will coincide with a favorable
time of day for mixing potential. The surface gradient looks to be
a little bit stronger compared to this past Saturday`s wind event
and there were spotty locations with sustained wind speeds of
30-35 mph. This front will have the potential for similar wind
speeds, but on a more widespread basis. This will include anywhere
from the Wenatchee Area, across the basin and over into the
exposed areas of the southern to central ID Panhandle. Winds up at
850 mbs look to peak at around 35-40 kts, which would translate to
a gust potential somewhere in the range of up to 40-45 mph. There
is a good possibility that a Wind Advisory will be needed for
Tuesday afternoon, but is still a bit early for a highlight at
this time this far out in the forecast period.

A 500 mb cold pool aloft will also result in the atmosphere
destabilizing through the afternoon. Showers will develop out
ahead of the cold front through the morning on Tuesday with more
showers likely developing in the conditionally unstable atmosphere
through the afternoon hours. Best chances for showers are expected
across the eastern half of the forecast area. There will also be a
chance for thunderstorms in the afternoon across the Okanogan
Highlands over into the Northern Panhandle.

Tuesday night through Sunday: A cold upper level trough of lower
pressure will hang around through Thursday. The cold front on
Tuesday will usher in colder temperatures with temperatures
closer to or slightly below normal. The cold upper level trough
will result in afternoon showers with the potential for some soft
hail or graupel. Shortwave ridging of higher pressure moves in
Thursday night, but another upper level trough of lower pressure
looks to drop down into the region for Friday through the
weekend. This will keep temperatures slightly below normal with
more convective showers expected, especially during the afternoon.

12Z TAFS: A couple of weak upper level disturbances will over-top
our flat upper level ridge today and tonight. Bands of mid and
high level clouds with ceilings at or above 12 thousand feet are
expected. Some light rain/high elevation snow will be possible
over the mountains along the Canadian border, but is not expected
to impact airports in the region. /GKoch

.SYNOPSIS...
The storm track will retreat north into Canada today and Monday
producing mild weather to the Inland Northwest. A vigorous spring
storm system will bring another chance for showers and strong
winds to our region on Tuesday. Wind gusts exceeding 40 mph will
be possible Tuesday afternoon and evening. Wednesday through next
weekend looks to be showery with temperatures near normal.


&&

.DISCUSSION...

...STRONG COLD FRONT TO DELIVER WINDY CONDITIONS ACROSS THE INLAND
NORTHWEST TUESDAY AFTERNOON...

Today through Monday: A flat upper level ridge at 500mb will
reside over the Pacific Northwest today into Monday. Vancouver
Island and the southern coast of British Columbia will experience
periods of rain during the next couple of days as a plume of
subtropical moisture is directed into southwestern Canada. Small
chances for light rain will extend as far south as the mountains
of far north central and northeast Washington today and tonight,
but the majority of our forecast area should be dry under bands of
mid and high level clouds. There will be much less wind today and
Monday with the typical afternoon increase in southwest winds,
generally in the 10 to 15 mph range. /GKoch

Tuesday: A vigorous cold front will seep across the region
Tuesday morning with the upper level trough of lower pressure
moving in for the afternoon. Models are in good agreement with a
deepening surface low scooting across southern BC into southern
Alberta through the day on Tuesday. Models all show the surface
low bottoming out at around 992 mbs along the eastern Divide in
southern Alberta by the afternoon hours. This will set up a
strong surface gradient, which will coincide with a favorable
time of day for mixing potential. The surface gradient looks to be
a little bit stronger compared to this past Saturday`s wind event
and there were spotty locations with sustained wind speeds of
30-35 mph. This front will have the potential for similar wind
speeds, but on a more widespread basis. This will include anywhere
from the Wenatchee Area, across the basin and over into the
exposed areas of the southern to central ID Panhandle. Winds up at
850 mbs look to peak at around 35-40 kts, which would translate to
a gust potential somewhere in the range of up to 40-45 mph. There
is a good possibility that a Wind Advisory will be needed for
Tuesday afternoon, but is still a bit early for a highlight at
this time this far out in the forecast period.

A 500 mb cold pool aloft will also result in the atmosphere
destabilizing through the afternoon. Showers will develop out
ahead of the cold front through the morning on Tuesday with more
showers likely developing in the conditionally unstable atmosphere
through the afternoon hours. Best chances for showers are expected
across the eastern half of the forecast area. There will also be a
chance for thunderstorms in the afternoon across the Okanogan
Highlands over into the Northern Panhandle.

Tuesday night through Sunday: A cold upper level trough of lower
pressure will hang around through Thursday. The cold front on
Tuesday will usher in colder temperatures with temperatures
closer to or slightly below normal. The cold upper level trough
will result in afternoon showers with the potential for some soft
hail or graupel. Shortwave ridging of higher pressure moves in
Thursday night, but another upper level trough of lower pressure
looks to drop down into the region for Friday through the
weekend. This will keep temperatures slightly below normal with
more convective showers expected, especially during the afternoon.

.SYNOPSIS...
The weather Sunday and Monday should be mild and relatively dry.
Another fast moving front on Tuesday will bring more showers and
windy conditions. The pattern of unsettled weather will continue
through the work week.

&&

.DISCUSSION...
The forecast has been updated for latest wind/sky cover trends.
Overall these changes were very minor.

With the setting sun and loss of daytime heating the lower
atmosphere will continue to stabilize through tonight. Winds early
this evening have decreased with this trend expected to continue
through the night as pressure gradients relax. Otherwise expect
mid and high clouds to continue to pass through the region tonight
as a moist frontal system remains aimed north of the Canadian
border from Vancouver Island into southern British Columbia. These
mid and high clouds are expected to increase overnight...which
should prevent fog formation in the northern valleys...although a
few stray patches can not be ruled out. Radar composites indicate
showers have ended across the area...except near the Cascade crest

.SYNOPSIS...
The weather Sunday and Monday should be mild and relatively dry.
Another fast moving front on Tuesday will bring more showers and
windy conditions. The pattern of unsettled weather will continue
through the work week.

&&

.DISCUSSION...
The forecast has been updated for latest wind/sky cover trends.
Overall these changes were very minor.

With the setting sun and loss of daytime heating the lower
atmosphere will continue to stabilize through tonight. Winds early
this evening have decreased with this trend expected to continue
through the night as pressure gradients relax. Otherwise expect
mid and high clouds to continue to pass through the region tonight
as a moist frontal system remains aimed north of the Canadian
border from Vancouver Island into southern British Columbia. These
mid and high clouds are expected to increase overnight...which
should prevent fog formation in the northern valleys...although a
few stray patches can not be ruled out. Radar composites indicate
showers have ended across the area...except near the Cascade crest
where a few showers will remain possible through the night. JW

.SYNOPSIS...
Showers will linger...but quickly end...over the Idaho Panhandle
very early in the evening. The gusty winds will also diminish
significantly. The weather Sunday and Monday should be mild and
relatively dry. Another fast moving front on Tuesday will bring
more showers and windy conditions. The pattern of unsettled
weather will continue through the work week.

&&

.DISCUSSION...
Tonight and Sunday: With the rapid exit east of the unstable short-
wave trough that helped to produce showers and very windy wx
across Ern Wa and N Idaho today, we`ll shortly transition into
stable upper ridging overnight. The result will be dry wx,
decreasing winds, and possibly some valley fog. Just offshore is a
warm frontal boundary that will move quickly east through the
region by midday Sunday that will keep skies mostly cloudy for
most towns. As far as pcpn chances with this front, most model
guidance shows very light amnts of rain for mainly NE Wa and N
Idaho coincident with the band of WAA/isentropic ascent. Pass
level snow is possible, but accumulations will be light, if any,
down to around 4500 ft. Confidence levels are low as far as a
patchy light rain reaching the lower elevations such as Spokane.
We have dry fcst attm. bz

Sunday Night through Monday: As remnants of the previous system
continue to push out the region and a ridge pattern begins to
build, the higher terrain of the Cascades and Idaho Panhandle
could receive a rain shower. By Monday, the chance of precip is
near non existent and warm and drier is pushes temperatures a few
degrees higher than the previous days.

...Strong winds Expected Tuesday...

Beginning late Monday, early Tuesday, the ridge begins to
breakdown as a cold front begins to press into the region. This is
expected to bring rain showers for most populated locations in the
region. Snow levels will be above 4500 feet. A combination of the
cooler air aloft, orographic lift, and diurnal surface heating
could produce an isolated thunderstorm in Southeastern Washington
and Central Idaho region but the confidence is very low. The winds
behind the front will be strong. Sustained winds of 20 to 30 MPH
and gusts near 40 MPH are expected in the Columbia Basin.
temperatures are expected to be near the season normals for this
time of year. /JDC

Tuesday night through Saturday...westerly flow in the wake of the
departing cold front will give way to another upper level trough
that will bring another round of precipitation to the Inland
Northwest for Wednesday and Wednesday night. Windy conditions
behind the front will subside overnight. The cold pool aloft will
result in unstable conditions and a couple hundred J/kg of CAPE
will be available for the late afternoon and early evening hours
across the northern zones both Wednesday and Thursday but with
little in the way of a warm front ahead of the trough, it appears
that the atmosphere will be too cold for thunder but favorable for
graupel showers. There will be a very brief break in the unsettled
weather late Thursday or Friday as a transient ridge pops up
between the exiting trough and the next one in line to affect the
Inland Northwest. Models have yet come into agreement on the
timing of the ridge but with lingering instability and westerly
flow, the threat of isolated to scattered upslope showers will
remain for the rising terrain east of the basin. Cold air aloft
will foster instability showers that could bring snow pellets down
to most valley floors. The Pacific trough that will affect the
region over the weekend will be deeper and colder than the mid
week system but timing is again in question. If we manage to get
partial clearing conditions during the overnight hours, there
remains the possibility of sub-freezing temperatures for all but
the lowest valleys but this is a low confidence forecast at this
time. /Kelch

.SYNOPSIS...
Showers will linger...but quickly end...over the Idaho Panhandle
very early in the evening. The gusty winds will also diminish
significantly. The weather Sunday and Monday should be mild and
relatively dry. Another fast moving front on Tuesday will bring
more showers and windy conditions. The pattern of unsettled
weather will continue through the work week.

&&

.DISCUSSION...
Tonight and Sunday: With the rapid exit east of the unstable short-
wave trough that helped to produce showers and very windy wx
across Ern Wa and N Idaho today, we`ll shortly transition into
stable upper ridging overnight. The result will be dry wx,
decreasing winds, and possibly some valley fog. Just offshore is a
warm frontal boundary that will move quickly east through the
region by midday Sunday that will keep skies mostly cloudy for
most towns. As far as pcpn chances with this front, most model
guidance shows very light amnts of rain for mainly NE Wa and N
Idaho coincident with the band of WAA/isentropic ascent. Pass
level snow is possible, but accumulations will be light, if any,
down to around 4500 ft. Confidence levels are low as far as a
patchy light rain reaching the lower elevations such as Spokane.
We have dry fcst attm. bz

Sunday Night through Monday: As remnants of the previous system
continue to push out the region and a ridge pattern begins to
build, the higher terrain of the Cascades and Idaho Panhandle
could receive a rain shower. By Monday, the chance of precip is
near non existent and warm and drier is pushes temperatures a few
degrees higher than the previous days.

...Strong winds Expected Tuesday...

Beginning late Monday, early Tuesday, the ridge begins to
breakdown as a cold front begins to press into the region. This is
expected to bring rain showers for most populated locations in the
region. Snow levels will be above 4500 feet. A combination of the
cooler air aloft, orographic lift, and diurnal surface heating
could produce an isolated thunderstorm in Southeastern Washington
and Central Idaho region but the confidence is very low. The winds
behind the front will be strong. Sustained winds of 20 to 30 MPH
and gusts near 40 MPH are expected in the Columbia Basin.
temperatures are expected to be near the season normals for this
time of year. /JDC

Tuesday night through Saturday...westerly flow in the wake of the
departing cold front will give way to another upper level trough
that will bring another round of precipitation to the Inland
Northwest for Wednesday and Wednesday night. Windy conditions
behind the front will subside overnight. The cold pool aloft will
result in unstable conditions and a couple hundred J/kg of CAPE
will be available for the late afternoon and early evening hours
across the northern zones both Wednesday and Thursday but with
little in the way of a warm front ahead of the trough, it appears
that the atmosphere will be too cold for thunder but favorable for
graupel showers. There will be a very brief break in the unsettled
weather late Thursday or Friday as a transient ridge pops up
between the exiting trough and the next one in line to affect the
Inland Northwest. Models have yet come into agreement on the
timing of the ridge but with lingering instability and westerly
flow, the threat of isolated to scattered upslope showers will
remain for the rising terrain east of the basin. Cold air aloft
will foster instability showers that could bring snow pellets down
to most valley floors. The Pacific trough that will affect the
region over the weekend will be deeper and colder than the mid
week system but timing is again in question. If we manage to get
partial clearing conditions during the overnight hours, there
remains the possibility of sub-freezing temperatures for all but
the lowest valleys but this is a low confidence forecast at this
time. /Kelch

&&

.AVIATION...
18Z TAFS: Strong post-frontal winds will impact the TAF sites
through mid to late afternoon today. West winds sustained 20 to
25kts with gusts up to 35kts are expected with the highest gusts
at KGEG and KPUW. Rain over the Idaho Panhandle will continue to
decrease. A broken cumulus deck will likely bring a 2500 to 4000
deck back to Coeur D`Alene, Sandpoint, and possibly Spokane Felts
by after 18-20z. Winds will diminish quickly with the setting
sun.bz

.SYNOPSIS...
Today will be quite windy, especially in the morning. West winds
of 15 to 25 mph with gusts over 30 mph will be common throughout
the Inland Northwest with gusts as high as 45 mph over the
Palouse. Showers will linger over the Idaho Panhandle through
early this afternoon. The weather Sunday and Monday should be mild
and relatively dry. Another fast moving front on Tuesday will
bring more showers, wind, and onset to another few days of
unsettled weather.

&&

.DISCUSSION...
Rest of today: The most significant changes to the fcst was to
extend the wind advsy for a few more hours for the Palouse and
Pomeroy regions. The Spokane region is also experience low-end
advsy thresholds (30 mph with gusts to 45 mph) in places, but
we`ve decided to handle this with NOWCASTS given that these winds
are not expected to remain strong for an extended length of time.
Also... SCHWEITZER Mtn will still experience gusts to 50 mph
slowly decreasing during the day. The good news is that the vort
max helping to produce these winds and mountain/valley rain and
snow showers is rapidly translating east through the Idaho
Panhandle and into Montana. By late afternoon height-rises aloft
of 100m will significantly help to end the pcpn as the depth of
the unstable lapse rates rapidly shrinks. However... shallow
instability and upslope forcing into the Id Panhandle will produce
lingering showers into the first part of this evening. For
tonight... valley fog seems likely across the NE Wa and N Idaho

.DISCUSSION...

...Windy Today with the Highest Gusts This Morning Over the
Palouse...

Today: A cold front will race eastward this morning. By sunrise
most of the precipitation behind this front will clear eastern
Washington with showers lingering in Idaho through early
afternoon. Windy conditions are expected over most of the Inland
Northwest today, especially this morning.

* Winds: A Wind Advisory remains in effect for the Palouse and the
  Pomeroy area through 11 AM. As of 2 AM, the surface cold front
  extended from southern Alberta through northwest Montana into
  the southern Idaho Panhandle. Strong pressure rises in central
  Oregon had contributed to the tightening of the southwest
  gradient across Washington and north Idaho. As cold air
  advection steepens our low level lapse rates during the next
  couple of hours, momentum transfer from 850mb and above will
  become more efficient allowing wind of 40 kts to mix to the
  surface in east and southeast Washington. The rising terrain of
  the Palouse, Foothills of the Blue Mountains, and the Pomeroy
  area should experience the strongest winds under the core of the
  low level jet. The West Plains and Waterville Plateau may also
  experience gusts of 40 mph or more which will be close to
  Advisory criteria. The highest gust potential will be this
  morning. By afternoon, low pressure will be racing through the
  Canadian Prairies and our surface gradient will relax a bit.
  Breezy conditions will persist through sunset, but gusts should
  decrease into the 30-35 mph range by early afternoon.

* Precipitation: The surface front has outpaced the mid-level
  front driving most of the rain showers. We have seen a marked
  decrease in the amount of lightning as deep low level cold
  advection has taken a bite out of our instability. Little more
  than a handful of lightning strikes are expected for the
  remainder of this event with the best possibility along the
  Canadian border under the 500mb cold pool. Snow levels will fall
  to 5000 feet by late morning leading to some light accumulations
  on the high peaks of the Idaho Panhandle and the Cascades above
  pass levels.

Sunday: A flat ridge of upper level high pressure will develop
tonight in the wake of today`s storm. At this time, the models are
in decent agreement that the core of the Polar Jet will be
directed toward Vancouver Island and southern British Columbia
Sunday and Sunday night. Low rain/snow chances have been retained
along the Cascade Crest mainly north of Stevens Pass Sunday along
with a mention of a 20 percent chance over the mountain ridges
along the Canadian border near Northport and Priest Lake. The
remainder of the Inland Northwest should be dry with the most
significant cloud cover (mid/high clouds) north of Interstate 90.

Monday through Thursday:  The active spring like weather will
continue well into next week. Monday will be a transition day
with mostly dry conditions as midlevel flow buckles to the
southwest ahead of the next trof approaching. This will nudge any
lingering cloud cover northward bringing a strong potential for an
abundance of sunshine and mild temperatures across the region. The
next upper-level trof will push into the region Monday night and
linger through Thursday bringing several rounds of showers, gusty
winds, and more seasonal temperatures. The first round of showers
will accompany the leading cold front Monday night. Gusty winds
will develop behind the front and persist into Tuesday. Meanwhile,
the atmosphere will become increasingly unstable as the Polar jet
noses into southern Oregon and 500mb temperatures cool near -30C.
A combination of forcing along smaller scale circulations (ie vort
max), orographic ascent, and diurnal heating will promote numerous
clusters of showers and possibly a few thunderstorms. Overall, it
will be unsettled and showery but not the steady rains experienced
on the 25th. Monday will be the warmest and driest day. Tuesday
will be the windiest day with the potential for sustained winds
15-30 mph and gusts in excess of 40 mph. Winds remain breezy
through the week but not near the speeds expected Tuesday.

Thursday night through Saturday: The persistent trof lingering
through Thursday will finally eject to the east as yet another
deep upper-level trof near the coast. There should be a short-
lived break as one system departs and the second approaches the
coast but models are not in good agreement on the extent of this
break. GFS has a break of roughly 6-8 hours before the next
frontal system arrives Thur nt into Friday. This has support from
its ensemble mean but not the ECMWF which is roughly 24-30 hours
slower. So timing is a bit sketchy at this time but model
consensus is suggesting this will be another multi day trof and
much cooler than the previous few largely in response to high
pressure nosing into the Gulf of AK and drawing cooler air south
through Wrn Canada. As previously mentioned, numerous rounds of
showers will be possible from a combination of elements but in
comparison to the system for Tue-Thur, snow levels will be lower
for several days, thunder chances will be lower due to lack of
charge separation, and graupel or snow could fall to some valley
floors. In addition, look for temperatures to cool back several
degrees below normal. We will be keeping a very close eye on this
event with the potential for early freeze warnings. /sb

* Winds: A Wind Advisory remains in effect for the Palouse and the

  the southern Idaho Panhandle. Strong pressure rises in central
  Oregon had contributed to the tightening of the southwest

  advection steepens our low level lapse rates during the next
  couple of hours, momentum transfer from 850mb and above will

.SYNOPSIS...
Today will be quite windy, especially in the morning. West winds
of 15 to 25 mph with gusts over 30 mph will be common throughout
the Inland Northwest with gusts as high as 45 mph over the
Palouse. Showers will linger over the Idaho Panhandle through
early this afternoon. The weather Sunday and Monday should be
mild and relatively dry. Another fast moving front on Tuesday will
bring more showers, wind, and onset to another few days of
unsettled weather.

.DISCUSSION...

...Windy Today with the Highest Gusts This Morning Over the
Palouse...

Today: A cold front will race eastward this morning. By sunrise
most of the precipitation behind this front will clear eastern
Washington with showers lingering in Idaho through early
afternoon. Windy conditions are expected over most of the Inland
Northwest today, especially this morning.

* Winds: A Wind Advisory remains in effect for the Palouse and the
  Pomeroy area through 11 AM. As of 2 AM, the surface cold front
  extended from southern Alberta through northwest Montana into
  the southern Idaho Panhandle. Strong pressure rises in central
  Oregon had contributed to the tightening of the southwest
  gradient across Washington and north Idaho. As cold air
  advection steepens our low level lapse rates during the next
  couple of hours, momentum transfer from 850mb and above will
  become more efficient allowing wind of 40 kts to mix to the
  surface in east and southeast Washington. The rising terrain of
  the Palouse, Foothills of the Blue Mountains, and the Pomeroy
  area should experience the strongest winds under the core of the
  low level jet. The West Plains and Waterville Plateau may also
  experience gusts of 40 mph or more which will be close to
  Advisory criteria. The highest gust potential will be this
  morning. By afternoon, low pressure will be racing through the
  Canadian Prairies and our surface gradient will relax a bit.
  Breezy conditions will persist through sunset, but gusts should
  decrease into the 30-35 mph range by early afternoon.

* Precipitation: The surface front has outpaced the mid-level
  front driving most of the rain showers. We have seen a marked
  decrease in the amount of lightning as deep low level cold
  advection has taken a bite out of our instability. Little more
  than a handful of lightning strikes are expected for the
  remainder of this event with the best possibility along the
  Canadian border under the 500mb cold pool. Snow levels will fall
  to 5000 feet by late morning leading to some light accumulations
  on the high peaks of the Idaho Panhandle and the Cascades above
  pass levels.

Sunday: A flat ridge of upper level high pressure will develop
tonight in the wake of today`s storm. At this time, the models are
in decent agreement that the core of the Polar Jet will be
directed toward Vancouver Island and southern British Columbia
Sunday and Sunday night. Low rain/snow chances have been retained
along the Cascade Crest mainly north of Stevens Pass Sunday along
with a mention of a 20 percent chance over the mountain ridges
along the Canadian border near Northport and Priest Lake. The
remainder of the Inland Northwest should be dry with the most
significant cloud cover (mid/high clouds) north of Interstate 90.
/GKoch

Monday through Thursday:  The active spring like weather will
continue well into next week. Monday will be a transition day
with mostly dry conditions as midlevel flow buckles to the
southwest ahead of the next trof approaching. This will nudge any
lingering cloud cover northward bringing a strong potential for an
abundance of sunshine and mild temperatures across the region. The
next upper-level trof will push into the region Monday night and
linger through Thursday bringing several rounds of showers, gusty
winds, and more seasonal temperatures. The first round of showers
will accompany the leading cold front Monday night. Gusty winds
will develop behind the front and persist into Tuesday. Meanwhile,
the atmosphere will become increasingly unstable as the Polar jet
noses into southern Oregon and 500mb temperatures cool near -30C.
A combination of forcing along smaller scale circulations (ie vort
max), orographic ascent, and diurnal heating will promote numerous
clusters of showers and possibly a few thunderstorms. Overall, it
will be unsettled and showery but not the steady rains experienced
on the 25th. Monday will be the warmest and driest day. Tuesday
will be the windiest day with the potential for sustained winds
15-30 mph and gusts in excess of 40 mph. Winds remain breezy
through the week but not near the speeds expected Tuesday.

Thursday night through Saturday: The persistent trof lingering
through Thursday will finally eject to the east as yet another
deep upper-level trof near the coast. There should be a short-
lived break as one system departs and the second approaches the
coast but models are not in good agreement on the extent of this
break. GFS has a break of roughly 6-8 hours before the next
frontal system arrives Thur nt into Friday. This has support from
its ensemble mean but not the ECMWF which is roughly 24-30 hours
slower. So timing is a bit sketchy at this time but model
consensus is suggesting this will be another multi day trof and
much cooler than the previous few largely in response to high
pressure nosing into the Gulf of AK and drawing cooler air south
through Wrn Canada. As previously mentioned, numerous rounds of
showers will be possible from a combination of elements but in
comparison to the system for Tue-Thur, snow levels will be lower
for several days, thunder chances will be lower due to lack of
charge separation, and graupel or snow could fall to some valley
floors. In addition, look for temperatures to cool back several
degrees below normal. We will be keeping a very close eye on this
event with the potential for early freeze warnings. /sb

&&

.AVIATION...
06Z TAFS: A vigorous cold front will sweep across the region
overnight. Showers will increase across the region between 06-12Z
and then begin to shift eastward with frontal passage. Some of the
stronger cells will be capable of producing thunderstorms and/or
produce brief heavy rain. Best chances for thunderstorms will be
through 10Z across southeast WA and into the southern to central
portion of the Panhandle. This will include the KPUW and KLWS TAF
sites with gusty outflow winds up to 40 mph and pea sized hail a
possibility with these thunderstorms. Widespread gusty westerly
winds will commence as showers shift east behind the front.
Sustained winds of 20-30 mph with gusts up to 45 mph will be
possible through Saturday afternoon. /SVH

.SYNOPSIS...
A fast moving cold front will arrive tonight bringing widespread
showers, gusty winds, and the potential for thunderstorms to
southeast Washington and portions of the Idaho Panhandle. Saturday
will be quite windy with gusts of 40 mph possible over Palouse,
West Plains, and Upper Columbia Basin. The weather Sunday and
Monday should be mild and relatively dry. Another fast moving
front on Tuesday will bring more showers and wind.

&&

.DISCUSSION...
Evening update: The cold front is just beginning to push into
western WA late this evening. Mid levels of the atmosphere will
continue to moisten across the forecast area ahead of the cold
front. A shallow pocket of mid level instability will exist
between 650-400 mbs across much of the region, especially across
the southern portions of the region. Even though this instability
is weak and relatively shallow, it is in a favorable location for
generating some charge separation. This will at least result in a
small chance for some isolated lightning strikes across the basin,
into the Okanogan Highlands and over to the ID Panhandle.

The axis of best instability continues to be from the northeast
Blue Mtns of OR up through southeast WA and into the southern to
central ID Panhandle. This is where the best potential for
thunderstorms exist through the rest of this evening. Occasional
cloud to ground lightning strikes, pea sized hail and gusty
outflow winds of up to 40 mph will be possible with any
thunderstorms that develop across this area. Instability becomes
even weaker the further north, so any thunderstorms that do
develop are expected to have as much of an impact.

Cold front passage is still on track for the overnight hours. The
new 00Z NAM model guidance has the cold front pushing east of the
Cascades around 11 PM and then into the ID Panhandle between
9-12Z. Showers will increase in coverage across the area between
this time. Winds will then become gusty with frontal passage. The
GFS continues to be the strongest guidance with the winds, but is
more of an outlier. Most of the other model guidance has the
strongest winds across the Blue Mtns and into the Palouse. The
Upper Columbia Basin, Spokane Area and Coeur d`Alene Area will
also see some good wind gusts with the front that will continue
into the morning hours on Saturday. Sustained winds of up around
20-30 mph with gusts up to 45 mph will be possible. These winds
will then gradually decrease through the afternoon on Saturday.
No changes to the current Wind Advisory are expected at this time.

Area Forecast Discussion
National Weather Service Spokane WA
1054 PM PDT FRI MAR 27 2015

.SYNOPSIS...
A fast moving cold front will arrive tonight bringing widespread
showers, gusty winds, and the potential for thunderstorms to
southeast Washington and portions of the Idaho Panhandle. Saturday
will be quite windy with gusts of 40 mph possible over Palouse,
West Plains, and Upper Columbia Basin. The weather Sunday and
Monday should be mild and relatively dry. Another fast moving
front on Tuesday will bring more showers and wind.

&&

.DISCUSSION...
Evening update: The cold front is just beginning to push into
western WA late this evening. Mid levels of the atmosphere will
continue to moisten across the forecast area ahead of the cold
front. A shallow pocket of mid level instability will exist
between 650-400 mbs across much of the region, especially across
the southern portions of the region. Even though this instability
is weak and relatively shallow, it is in a favorable location for
generating some charge separation. This will at least result in a
small chance for some isolated lightning strikes across the basin,
into the Okanogan Highlands and over to the ID Panhandle.

The axis of best instability continues to be from the northeast
Blue Mtns of OR up through southeast WA and into the southern to
central ID Panhandle. This is where the best potential for
thunderstorms exist through the rest of this evening. Occasional
cloud to ground lightning strikes, pea sized hail and gusty
outflow winds of up to 40 mph will be possible with any
thunderstorms that develop across this area. Instability becomes
even weaker the further north, so any thunderstorms that do
develop are expected to have as much of an impact.

Cold front passage is still on track for the overnight hours. The
new 00Z NAM model guidance has the cold front pushing east of the
Cascades around 11 PM and then into the ID Panhandle between
9-12Z. Showers will increase in coverage across the area between
this time. Winds will then become gusty with frontal passage. The
GFS continues to be the strongest guidance with the winds, but is
more of an outlier. Most of the other model guidance has the
strongest winds across the Blue Mtns and into the Palouse. The
Upper Columbia Basin, Spokane Area and Coeur d`Alene Area will
also see some good wind gusts with the front that will continue
into the morning hours on Saturday. Sustained winds of up around
20-30 mph with gusts up to 45 mph will be possible. These winds
will then gradually decrease through the afternoon on Saturday.
No changes to the current Wind Advisory are expected at this time.
/SVH

&&

.AVIATION...
06Z TAFS: A vigorous cold front will sweep across the region
overnight. Showers will increase across the region between 06-12Z
and then begin to shift eastward with frontal passage. Some of the
stronger cells will be capable of producing thunderstorms and/or
produce brief heavy rain. Best chances for thunderstorms will be
through 10Z across southeast WA and into the southern to central
portion of the Panhandle. This will include the KPUW and KLWS TAF
sites with gusty outflow winds up to 40 mph and pea sized hail a
possibility with these thunderstorms. Widespread gusty westerly
winds will commence as showers shift east behind the front.
Sustained winds of 20-30 mph with gusts up to 45 mph will be
possible through Saturday afternoon. /SVH
