.DISCUSSION...

Gusty southerly winds continue to gust into the mid 40s in
Grangeville and vicinity this afternoon. Expect these winds to
continue through early evening. Southwesterly flow aloft with an
abundant moisture plume continues to support a stream of showers
moving through the region today. Snow levels have been around 7000
ft or higher for this system keeping any snow accumulations
limited to the higher peaks. So far, mountains have received a few
tenths to around an inch including Lookout Pass, while valleys
have been generally shadowed with this system.

Already there has been lightning reported in the showers near the
Washington and Idaho State line. There is a low potential for a
few isolated thunderstorms from central Idaho into northwest
Montana this afternoon and evening as model soundings suggest
modest instability. The biggest threat would be for the stronger
showers to bring down gusty winds between 35 and 40 mph. It
doesn`t take much to bring down a few small trees across these
areas especially those that have received rainfall already today,
so that will have to be monitored by the evening shift.

A few showers will linger through Friday before drier weather
temporarily returns for later Friday and Saturday. The Camas
Prairie region will once again see some gusty winds Saturday
afternoon as another tight southerly pressure gradient develops.
Gust approaching 40 mph will not be out of the question.

A much cooler system with snow levels lowering to 4000-5000 ft
will approach the region late Saturday/early Sunday, keeping high
temperatures cooler than normal and bringing additional
widespread rain and snow showers. Windy southwest winds are
expected with this system, potentially gusting to 35 to 45 mph
over the mountain ridges. The southwesterly winds could also
create choppy conditions on area lakes, especially Flathead Lake.
Off and on rain and snow showers are possible through Monday with
northwest flow. A few flakes could also be visible down to valley
floors Monday morning, however nothing to amount to any impacts.

Unsettled weather will continue the middle to late next week with
models indicating a few weather disturbances moving through the
region. Temperatures will be at or below normal. Models are pretty
inconsistent with each other so confidence is pretty low for any
timing of weather systems and their impacts.

&&

.AVIATION...The plume of moisture is expected to shift southward
with time through this evening. There is the small possibility
that a few of the showers over central Idaho into west-central
Montana could become intense enough to support isolated lightning
and strong gusty winds near 35 knots. The frontal zone will stall
from central Idaho County in Idaho east to Deer Lodge, Montana by
24/0900z. This will be the focus for continued moderate to perhaps
heavy showers and mountain obscurations through Friday afternoon.
There will be a lull in the precipitation at KGPI tonight into
Friday and with a weak surface pressure gradient, fog could form
by 24/1200z there. The aforementioned stalled frontal boundary
will lift north into northwest Montana as a warm front after
25/0000z(Friday evening).

.DISCUSSION...SOUTHWESTERLY FLOW ALOFT WILL CONTINUE TO ALLOW A
PLUME OF SUBTROPICAL MOISTURE STREAM THROUGH THE NORTHERN ROCKIES
TODAY. WIDESPREAD PRECIPITATION IS ANTICIPATED WITH THE MOUNTAINS
POTENTIALLY GETTING AN INCH OR TWO OF RAIN BY FRIDAY MORNING. THE
STRONG FLOW ALOFT WILL CAUSE DOWNSLOPING EFFECTS IN THE BROADER
VALLEYS, BUT LOCATIONS LIKE KALISPELL AND MISSOULA SHOULD STILL
RECEIVE MEASURABLE RAIN. SNOW LEVELS ARE ANTICIPATED TO BE AROUND
6000-7000 FEET DURING THIS EVENT. TEMPERATURES WILL HAVE A
DIFFICULT TIME WARMING TODAY DUE TO PRECIPITATION AND CLOUD COVER.

A RIDGE OF HIGH PRESSURE WILL BUILD BACK OVER THE REGION LATE
FRIDAY INTO SATURDAY GIVING WAY TO A WARMING AND DRYING TREND.
TEMPERATURES FOR SATURDAY SHOULD BE ABOVE NORMAL FOR THIS TIME OF
YEAR.

A SIGNIFICANT SYSTEM IS EXPECTED TO SWING THROUGH THE REGION ON
SUNDAY INTO MONDAY. THIS SYSTEM WILL BRING ANOTHER ROUND OF
WIDESPREAD PRECIPITATION WITH COOL AND RAW CONDITIONS ON SUNDAY.
SNOW LEVELS HAVE TO POTENTIAL TO DROP TO NEAR 4000 FEET BY MONDAY
MORNING.


&&

.AVIATION...ALL AVIATION SITES WILL SEE A CHANCE OF RAIN
OCCASIONALLY REDUCING VISIBILITIES AND LOWERING CEILINGS AFTER
1500Z. GUSTY SOUTHWEST WINDS WILL ALSO DEVELOP TOMORROW AFTERNOON
FOR ALL TERMINALS, WITH GUSTS APPROACHING 25 TO 30 MPH AFTER
1800Z.

250 PM MDT WED OCT 22 2014

...Wet & raw backcountry conditions expected tomorrow...
...Strong gusty winds in the Camas Prairie & Grangeville area
tonight through tomorrow morning...

.DISCUSSION...A wet southwest flow pattern is on tap beginning
tonight and continuing through at least Thursday night. The
moisture content of the atmosphere is above normal due to
subtropical origins and this will be a factor in allowing for
typical up-slope locations to receive anywhere from 0.50 to 1
of total precipitation through Friday morning. A few of the CIPS
analog/pattern matches confirm that Clearwater, Cabinet & Purcell
Mountains and Bitterroot ranges near the Montana and Idaho border
as well as from Glacier National Park south to the Mission
Mountains will see the highest precipitation amounts. Valley
locations will see considerably less precipitation due to down-
sloping effects but still will be able to see up to a 0.25 inches
of rain. Model soundings show the potential for strong gusty winds
to develop in the Grangeville and Camas Prairie area tonight
especially from 2 to 9 am PDT. Therefore we have issued a wind
advisory there for southerly winds 25 to 30 mph with gusts to 45
mph. By Thursday afternoon temperatures will warm into the 50s and
generally breezy conditions will be felt across the region. There
is the chance that Flathead Lake winds could become gusty over 20
mph at times, but confidence is low at this time.

A weak system will track from south to north Friday morning
spreading a few light rain showers from southwestern Montana and
central Idaho north into western Montana. Showers will pretty much
come to and end by Friday night as a brief ridge of high pressure
will build north into western Montana, which will lead to a nice
day on Saturday. Breezy conditions are expected to develop
Saturday afternoon especially for the mountains ahead of the next
system by the end of the weekend.

As the system approaches and moves through Sunday, southwest
winds will increase...especially over higher terrain. Cooler,
showery weather is expected to continue Sunday and into Monday
with snow impacting areas above 4000-5000ft. Another heavier wave
of precipitation will push through beginning Tuesday with
lingering showers lasting through the week.

&&

.AVIATION...Fair flying conditions in store for the rest of the
day across western Montana and central Idaho. Clouds will be on
the increase overnight with rain showers developing by the
morning. All aviation sites will see a chance of rain occasionally
reducing visibilities and lowering ceilings after 1500Z. Gusty
southwest winds will also develop tomorrow afternoon for all
terminals, with gusts approaching 25 to 30 mph after 1800Z.

Area Forecast Discussion
National Weather Service Missoula MT
329 AM MDT WED OCT 22 2014

.DISCUSSION...High pressure has moved into Idaho and western
Montana overnight and helped cloud cover to decrease and fog to
form in many areas. The mix of low clouds and fog will last into
mid morning.

The next trough is moving onto the west coast with cloud cover
spreading ahead of it. This cloud cover will keep high
temperatures from reaching their full potential today, though,
near to just above normal temperatures can be expected.
Precipitation with the next weather system is forecast to move
into far northwest Montana this evening followed by the rest of
northwest Montana and north central Idaho overnight. The strong
upper jet with this trough could still produce a few thunderstorms
late Thursday so the chance remains in the forecast. Gusty
westerly winds should also be anticipated for Thursday afternoon
and evening. Precipitation will linger through Friday.

Model guidance now agree that weak ridge will build back into
Idaho and western Montana Saturday morning ahead of another
trough, so one change to the extended forecast has been to dry
the forecast for Friday night. This next trough will pass on
Sunday and Monday with cool and showery conditions.

Weak high pressure may build for Tuesday before another possible
trough on Wednesday.


&&

.AVIATION...Clouds are on a general decreasing trend through the
region this morning as weak high pressure passes over Idaho and
western Montana. The exception to clearing skies is that low level
moisture, left from yesterday`s rain, has caused fog and stratus
to build. A mix of fog and stratus will last through mid morning.
Cloud cover ahead of an approaching trough is already moving into
Washington and will pass through the region with lowering cloud
bases through today. Downslope winds are still expected along the
Rocky Mountain Front of Glacier National Park so watch out for
mountain wave activity. Obscured terrain and precipitation will
spread through northwest Montana and north central Idaho overnight
tonight.

755 PM MDT TUE OCT 21 2014

.UPDATE...Cancelled the winter weather advisories.


&&

.DISCUSSION...Due to precipitation ending and subsequent impacts
diminishing, the winter weather advisories have been cancelled.
Some lingering light snow showers may still plague mountain passes
through the rest of this evening, but the impacts have lessened
enough to warrant the cancellation of headlines.

&&

.PREV DISCUSSION... /ISSUED /

.DISCUSSION...A lot of rain has fallen across the area today, with
many locations reporting over 0.3 inches of rain in the last 24
hours, with many mountain stations reporting over half an inch of
new liquid. Snow was also observed at elevations above 6000 feet
south of Missoula.

As this system exits the area tonight, scattered low clouds and
patchy fog will develop across the northern Rockies due to the
ample moisture left behind. High pressure centered over Southwest
Montana and Lemhi county Idaho will drive light southerly winds
over much of western Montana tonight, keeping the fog patchy and
limited to areas sheltered from southerly winds. Also, much less
rain fell over northwest Montana, so fog is less likely there. In
central Montana, the southerly winds will be stronger preventing
fog from forming in the Grangeville and Orofino or on the Camas
Prairie.

On Wednesday high pressure will intensify as a ridge builds over
the area. This will continue to drive southerly winds and allow
temperatures to rise to above normal readings again. A strong jet
stream with very moist flow will move across the Pacific
Northwest, just glancing the northwest corner of northwest Montana
ahead of the next system, mainly affecting Troy before more
moisture from this system starts to move into western Montana
Thursday.

The Thursday system is forecast to bring rain and high elevation
snow showers, with breezy southwest winds across much of the area.
Showers with possible thunder is forecast for southwest MT and
central ID along the Bitterroot Mountains. The cool and wet
pattern will continue through the weekend and into early next
week. Some showers could produce heavier precipitation with a
colder airmass late Sunday into Monday, resulting in snow levels
dropping to the mid slopes around 4500ft.

&&

.AVIATION...The weather system that brought gusty winds, rain &
snow and scattered thunderstorms to the area will be moving into
central Montana by 22/0300Z causing shower activity to wane. Mountain
obscuration will continue through tonight due to westerly flow
keeping upslope showers in place. There will be somewhat drier air
moving in aloft after 22/0800z which could help improve ceilings
especially across central Idaho and areas west of the Continental
Divide. Considering all the rainfall that fell and some clearing
tonight, the chance for fog exists. There may be too much of a
southerly breeze to form widespread fog from KGPI to KBTM, but
confidence is higher that KSMN could see better development
overnight tonight. VFR conditions are expected to develop on
Wednesday at all the terminals. With increasing flow aloft, there
could be weak to moderate mountain wave activity across the
Continental Divide especially towards the Canadian Border on
Wednesday.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
228 PM MDT TUE OCT 21 2014

.DISCUSSION...A LOT OF RAIN HAS FALLEN ACROSS THE AREA TODAY, WITH
MANY LOCATIONS REPORTING OVER 0.3 INCHES OF RAIN IN THE LAST 24
HOURS AND MANY MOUNTAIN STATIONS REPORTING OVER HALF AN INCH OF
NEW LIQUID. SNOW WAS ALSO OBSERVED AT ELEVATIONS ABOVE 6000 FEET
SOUTH OF MISSOULA.

AS THIS SYSTEM EXITS THE AREA TONIGHT, SCATTERED LOW CLOUDS AND
PATCHY FOG WILL DEVELOP ACROSS THE NORTHERN ROCKIES DUE TO THE
AMPLE MOISTURE LEFT BEHIND. HIGH PRESSURE CENTERED OVER SOUTHWEST
MONTANA AND LEMHI COUNTY IDAHO WILL DRIVE LIGHT SOUTHERLY WINDS
OVER MUCH OF WESTERN MONTANA TONIGHT, KEEPING THE FOG PATCHY AND
LIMITED TO AREAS SHELTERED FROM SOUTHERLY WINDS. ALSO, MUCH LESS
RAIN FELL OVER NORTHWEST MONTANA, SO FOG IS LESS LIKELY THERE. IN
CENTRAL MONTANA, THE SOUTHERLY WINDS WILL BE STRONGER PREVENTING
FOG FROM FORMING IN THE GRANGEVILLE AND OROFINO OR ON THE CAMAS
PRAIRIE.

ON WEDNESDAY HIGH PRESSURE WILL INTENSIFY AS A RIDGE BUILDS OVER
THE AREA. THIS WILL CONTINUE TO DRIVE SOUTHERLY WINDS AND ALLOW
TEMPERATURES TO RISE TO ABOVE NORMAL READINGS AGAIN. A STRONG JET
STREAM WITH VERY MOIST FLOW WILL MOVE ACROSS THE PACIFIC
NORTHWEST, JUST GLANCING THE NORTHWEST CORNER OF NORTHWEST MONTANA
AHEAD OF THE NEXT SYSTEM, MAINLY AFFECTING TROY BEFORE MORE
MOISTURE FROM THIS SYSTEM STARTS TO MOVE INTO WESTERN MONTANA
THURSDAY.

THE THURSDAY SYSTEM IS FORECAST TO BRING RAIN AND HIGH ELEVATION
SNOW SHOWERS, WITH BREEZY SOUTHWEST WINDS ACROSS MUCH OF THE AREA.
SHOWERS WITH POSSIBLE THUNDER IS FORECAST FOR SOUTHWEST MT AND
CENTRAL ID ALONG THE BITTERROOT MOUNTAINS. THE COOL AND WET
PATTERN WILL CONTINUE THROUGH THE WEEKEND AND INTO EARLY NEXT
WEEK. SOME SHOWERS COULD PRODUCE HEAVIER PRECIPITATION WITH A
COLDER AIRMASS LATE SUNDAY INTO MONDAY, RESULTING IN SNOW LEVELS
DROPPING TO THE MID SLOPES AROUND 4500FT.

&&

.AVIATION...THE WEATHER SYSTEM THAT BROUGHT GUSTY WINDS, RAIN &
SNOW AND SCATTERED THUNDERSTORMS TO THE AREA WILL BE MOVING INTO
CENTRAL MONTANA BY 22/0300Z CAUSING SHOWER ACTIVITY TO WANE. MOUNTAIN
OBSCURATIONS WILL CONTINUE THROUGH TONIGHT DUE TO WESTERLY FLOW
KEEPING UPSLOPE SHOWERS IN PLACE. THERE WILL BE SOMEWHAT DRIER AIR
MOVING IN ALOFT AFTER 22/0800Z WHICH COULD HELP IMPROVE CEILINGS
ESPECIALLY ACROSS CENTRAL IDAHO AND AREAS WEST OF THE CONTINENTAL
DIVIDE. CONSIDERING ALL THE RAINFALL THAT FELL AND SOME CLEARING
TONIGHT, THE CHANCE FOR FOG EXISTS. THERE MAY BE TOO MUCH OF A
SOUTHERLY BREEZE TO FORM WIDESPREAD FOG FROM KGPI TO KBTM, BUT
CONFIDENCE IS HIGHER THAT KSMN COULD SEE BETTER DEVELOPMENT
OVERNIGHT TONIGHT. VFR CONDITIONS ARE EXPECTED TO DEVELOP ON
WEDNESDAY AT ALL THE TERMINALS. WITH INCREASING FLOW ALOFT, THERE
COULD BE WEAK TO MODERATE MOUNTAIN WAVE ACTIVITY ACROSS THE
CONTINENTAL DIVIDE ESPECIALLY TOWARDS THE CANADIAN BORDER ON
WEDNESDAY.

.DISCUSSION...The main area of lift is going to shift over north
central Idaho and west central Montana by sunrise this morning
with light to moderate rain and a few lightning strikes. A cold
front will move through this morning causing snow levels to lower
to around 5000 feet by this afternoon, so watch out for snow
accumulations in the high terrain and over mountain passes.
Temperatures have remained warm overnight and cooler air behind
the cold front will also generally cause a cooling trend through
the day.

The main shortwave with this system will pass this afternoon with Lemhi
County Idaho and southwest Montana expecting to receive the
heaviest amount of precipitation. Precipitation will quickly
decrease this evening as the trough moves off to the east and
drier air moves in.

Wednesday now looks to be mostly dry with morning fog as weak high
pressure moves over Idaho and western Montana.

A steady stream of moisture, evident on water vapor imagery,
extends through the eastern Pacific and is forecast to pass
through the region during the end of the week and this weekend in
the form of multiple troughs. This weather pattern for the
extended forecast period will promote near normal high
temperatures, above normal low temperatures, and periods of rain.

&&

.AVIATION...Cloud cover and rain are increasing early this morning
as the next weather system moves into the region. Idaho and
western Montana will lie in the optimum lift region this morning
with moderate rain showers and even a few lightning strikes
likely. Terrain will be obscured through most of the day with high
amounts of moisture passing with the trough. This trough will pass
this afternoon keeping rain and high elevation snow in eastern
Idaho and southwest Montana. Sky cover will begin to clear out
