...Light snow accumulations through much of north central Idaho
and western Montana through Monday morning...

...POTENTIAL HEAVY SNOW EVENT IN THE MOUNTAINS AND THROUGH
NORTHWEST MONTANA MONDAY NIGHT INTO WEDNESDAY...

.DISCUSSION...

Snow is beginning to expand throughout northern Idaho and
northwest Montana this afternoon as a shortwave trough approaches
the region. There is a high chance for most people to have light
snow accumulations by Monday morning as the trough continues to
trek through north central Idaho and western Montana. Widespread
slick roadways are possible overnight so winter weather advisories
are in effect.

POTENTIAL HEAVY SNOW:

A brief break in snow is possible Monday afternoon before the
next, potentially heavy snow producing, weather system arrives.
The next weather system is going to have a lot of moisture and
there is moderate to high confidence of the storm to develop but
snow levels are in question with much lower confidence. This
weather system will be warm front dominated so snow levels will
rise. The questions are, how quickly this transition will occur,
and will valley locations be able to see snow accumulations before
the rise? As of now there is fair agreement that precipitation
will start as snow Monday night and transition to rain at lower
elevations through Tuesday. High snow levels, above many mountain
passes, are possible late Tuesday into Wednesday. The valleys of
northwest Montana are of particular focus since snow levels will
be slower to rise leaving a higher chance for snow accumulations.
At this time only moderate snow accumulations are being forecast
in the northwest Montana valleys, but heavy snow is forecast for
high elevations. Travel impacts are becoming likely due to snow
Tuesday into Wednesday.

Precipitation may linger in northwest Montana into Thursday but
timing issues leave this uncertain.

There are indications that the moist flow will return for the
weekend as colder air moves in from the east. Snow will again be
possible through the weekend but confidence is low due to high
changeability in the extended model guidance.


&&

.AVIATION...Widespread snow will develop this evening with
localized snow bands forecast for the overnight. Low ceilings and
reduced visibilities can be expected throughout north central
Idaho and western Montana including all TAF sites through much of
tonight. Widespread light accumulations are expected through
Monday morning. Snow coverage will decrease early Monday morning
with lowest chances anticipated through the afternoon. Ceilings
improvements are also expected by Monday afternoon.

...Periods of snow and slick road conditions today and tonight on
mountain passes...

...Possible light valley snow tonight...

.DISCUSSION...Weak snow bands under northwest flow aloft will
continue periods of light snow and possibly areas of slick road
conditions through this morning. These bands are expected to
weaken through the morning. Those with travel plans this morning
should be prepared for changeable road conditions, especially over
mountain passes.

The next in a line of weather disturbances will quickly approach
western Montana and north central Idaho this afternoon and
evening. Another round of widespread precipitation will develop,
first in northwest Montana and the Idaho panhandle this afternoon,
sweeping into the rest of central Idaho and west-central/southwest
Montana this evening. Mountains and mountain passes will be the
first to be impacted with accumulating snow, once again degrading
road conditions. This system does have the potential to produce
snow down to the valley floors late tonight into Monday morning,
including for the Missoula/Bitterroot and Flathead/Mission
valleys, which could impact the Monday morning commute. Stay
tuned!

A brief dry window is expected on Monday before yet another
weather disturbance moves into the region beginning Monday night.
This next system has an impressive moisture tap and could lead to
significant mountain snowfall, possibly lasting into Wednesday.
Precipitation type for valley locations will be a bit trickier as
this system initially starts out cool, but gradually warms with
time. A period of valley snowfall is possible Monday night into
Tuesday night, though exact amounts and placement of best valley
snow will largely depend on how quickly warmer air is able to
infiltrate. Currently, valleys of northwest Montana stand the best
chance of measurable snow.

Forecast models continue to hint at a potentially colder and
snowy pattern developing late this week. Timing of the cold air
and possible over-running precipitation varies significantly
between model solutions, but confidence in this overall pattern
change is beginning to grow. This period will continue to be
monitored closely as travel impacts around the Thanksgiving
holiday are possible.


&&

.AVIATION...Localized snow bands changing over to more widespread
snow showers after 23/1900Z will make for active weather at
terminals today. Snow accumulations of an inch or so for KGPI and
KMSO are possible by 24/0600Z. KBTM and KSMN should see lighter
amounts in this time frame, but still enough to make runways
slick. Snow showers will lower visibilities and ceilings which
will obscure terrain into Monday morning. West winds in the 5 to
15 kt range can be expected in the valleys with this system, with
winds up to 35 kts near ridge tops.

.DISCUSSION...

Behind the cold front that passed through the region today snow
showers are expected to redevelop through north central Idaho,
west central Montana, and Lemhi County Idaho this evening. These
showers will keep snow accumulating on Lolo and Lost Trail passes.
These showers will continue into early Sunday with a decrease in
activity during the day before the next weather system arrives.

Another snow producing weather system will pass on Sunday night
that has a high chance to bring light snow accumulations through
much of north central Idaho and western Montana into early Sunday
morning. A rather lengthy winter weather advisory will be
maintained for the Bitterroots and Clearwater Mountains even
though there will likely be a distinct period of lesser impact
midday Sunday.

Drier conditions will return during the day Monday but a
potentially high impact, moist, weather system is becoming likely
for Monday night through Tuesday. This weather system should start
off cool in the valleys and have a very good Pacific moisture tap,
so widespread valley snow with heavy mountain snow is possible.

The weather could get even more interesting around Thanksgiving as
models area showing a moist northwest upper level flow developing
Wednesday over northwest Montana, while cold canadian surface air
slides into the area from the northeast. This could be a very good
snow pattern for northwest Montana Wednesday night and Thursday,
and over the remainder of western Montana and the higher terrain
of north Central Idaho Thursday and Thursday night. Model
consistency with this solution is new and still not ideal, keeping
forecast confidence relatively low. However, this will be looked
at closely over the next couple days.

&&

.AVIATION...Snow showers will develop later this afternoon through
north central Idaho and into west central Montana. Higher
elevations are expected to remain obscured with lowered
visibilities in snow. Lower elevations will only have periods of
lowered visibility overnight under stronger snow showers. High
pressure will briefly pass during the day on Sunday so cloud cover
will decrease somewhat and showers will decrease but this will all
be short-lived with another shortwave expected Sunday afternoon.

...Difficult travel this morning across western Montana and north
central Idaho due to snow and ice causing slick roads...

...Gusty winds this afternoon and evening...

.DISCUSSION...A very complicated weather scenario continues over
western Montana and north central Idaho this morning. Moderate to
locally heavy snow has developed across most mountain passes this
morning, including Lookout, Lost Trail, Lolo and Marias.
Meanwhile, most valley locations have seen mixed precipitation of
rain, freezing rain and snow. Despite the fact that many valley
locations have actually warmed above freezing overnight, sub
surface temperatures remain cold enough to allow ice to form,
especially on untreated roads, bridges, sidewalks and parking
lots. Between mountain pass snow and areas of ice in valley
locations, road conditions will be less than ideal, and travelers
should use extra caution.

Meanwhile, a strong cold front is currently moving through Idaho
and will move through western Montana this morning. With and
behind this cold front, strong gusty winds are expected to
develop, with gusts up to 40 mph likely, especially across
southwest Montana. This cold front will also allow snow levels to
drop through the afternoon, allowing precipitation to change over
to snow even in most valley locations by afternoon. This being
said, precipitation should become more showery in nature and thus
significant accumulations in the valleys are not anticipated.

Another passing disturbance is expected to move through northwest
flow aloft tonight. This feature looks to affect mainly north
central Idaho, with another round of snow for most locations. Some
of this precipitation could bleed over into west central and
southwest Montana, where even valleys (potentially
Missoula/Bitterroot) could see some light snow into Sunday
morning.

The active weather pattern is expected to continue early next
week. Another round of both mountain and valley snowfall is
possible Sunday night into Monday morning. Forecast models
continue to hint at the potential of some snow banding, so this
part of the forecast will continue to be monitored. Another moist
system is expected for Monday night into Tuesday, gradual warming
aloft will slowly increase snow level, especially by Tuesday
afternoon. However, initially another round of valley snow and
possibly even another bout of freezing rain is possible Monday
night into Tuesday morning.

Unfortunately, clarity has not come to the forecast for the middle
of next week, including for Thanksgiving. Forecast models
continue to alternate between a dry ridge of high pressure and a
potentially cold and snowy pattern. Confidence is low in the
overall weather pattern for this time frame and will be monitored
closely over the coming days.


&&

.AVIATION...Rain, snow, and gusty daytime winds will be concerns
for all terminals over the next 24 hours. Morning rain showers
will turn to scattered snow showers by this afternoon with the
passage of a cold front. Winds of 15 to 20 kts with higher gusts
to 30kt are likely with the frontal passage, which is expected
between 22/1600z and 22/1800z. Light snow accumulations this
evening cannot be ruled out at any terminal, but amounts are
expected to be less than an inch where occurring. Additionally,
reduced visibilities can be expected with snow showers.

.DISCUSSION...A very complicated weather scenario continues over
western Montana and north central Idaho this morning. Moderate to
locally heavy snow has developed across most mountain passes this
morning, including Lookout, Lost Trail, Lolo and Marias.
Meanwhile, most valley locations have seen mixed precipitation of
rain, freezing rain and snow. Despite the fact that many valley
locations have actually warmed above freezing overnight, sub
surface temperatures remain cold enough to allow ice to form,
especially on untreated roads, bridges, sidewalks and parking
lots. Between mountain pass snow and areas of ice in valley
locations, road conditions will be less than ideal, and travelers
should use extra caution.

Meanwhile, a strong cold front is currently moving through Idaho
and will move through western Montana this morning. With and
behind this cold front, strong gusty winds are expected to
develop, with gusts up to 40 mph likely, especially across
southwest Montana. This cold front will also allow snow levels to
drop through the afternoon, allowing precipitation to change over
to snow even in most valley locations by afternoon. This being
said, precipitation should become more showery in nature and thus
significant accumulations in the valleys are not anticipated.

Another passing disturbance is expected to move through northwest
flow aloft tonight. This feature looks to affect mainly north
central Idaho, with another round of snow for most locations. Some
of this precipitation could bleed over into west central and
southwest Montana, where even valleys (potentially
Missoula/Bitterroot) could see some light snow into Sunday
morning.

The active weather pattern is expected to continue early next
week. Another round of both mountain and valley snowfall is
possible Sunday night into Monday morning. Forecast models
continue to hint at the potential of some snow banding, so this
part of the forecast will continue to be monitored. Another moist
system is expected for Monday night into Tuesday, gradual warming
aloft will slowly increase snow level, especially by Tuesday
afternoon. However, initially another round of valley snow and
possibly even another bout of freezing rain is possible Monday
night into Tuesday morning.

Unfortunately, clarity has not come to the forecast for the middle
of next week, including for Thanksgiving. Forecast models
continue to alternate between a dry ridge of high pressure and a
potentially cold and snowy pattern. Confidence is low in the
overall weather pattern for this time frame and will be monitored
closely over the coming days.


&&

.AVIATION...Rain, snow, and gusty daytime winds will be concerns
for all terminals over the next 24 hours. Morning rain showers
will turn to scattered snow showers by this afternoon with the
passage of a cold front. Winds of 15 to 20 kts with higher gusts
to 30kt are likely with the frontal passage, which is expected
between 22/1600z and 22/1800z. Light snow accumulations this
evening cannot be ruled out at any terminal, but amounts are
expected to be less than an inch where occurring. Additionally,
reduced visibilities can be expected with snow showers.

...Mountain snow and valley mixed precipitation tonight...

...Gusty winds with rain and snow on Saturday...

.DISCUSSION...

The next moist weather system is moving through Washington this
afternoon and will arrive in Idaho and western Montana this
evening. Light snow will begin to fall at elevations above around
4500 feet with rain or a mix of rain and snow below. Many valley
locations that have remained cool have a chance for a light
rain/snow mix to potentially freeze on surfaces overnight
including Kalispell, Missoula, Libby, and points between. Snow
over mountain passes will increase in intensities overnight with
the heaviest snow anticipated with the cold front. The front is
forecast to pass at Lookout and Lolo passes Saturday morning and
Lost Trail, Homestake, MacDonald, and Gilmore Summit through the
afternoon. Gusty winds will also develop with the cold front
mainly south of I-90 with gusts as high as 50 mph. Snow showers
will continue through Saturday overnight especially in north
central Idaho and Lolo/Lost Trail passes.

Another weather disturbance arriving Sunday morning will generate
additional snowfall across much of the region with activity
lasting into the evening hours. In fact, some mountain locations
will continue to experience snow showers well into Monday. Winds
will be lighter compared to those anticipated on Saturday but
mountain pass snowfall amounts will be similar. Additionally, snow
levels will lower to valley bottoms on Sunday with 1-2 inches of
snowfall possible for many valley areas. Some indicators are
suggesting a chance of snow bands setting up over western Montana
on Monday morning, which could impact the morning commute.

Cool and unsettled conditions will prevail early next week with
forecast models advertising fairly widespread mountain snow and a
valley rain/snow mix on Tuesday. Models are now trending toward a
dry ridge of high pressure moving overhead Wednesday into
Thanksgiving, which is the complete opposite of what some model
runs indicated earlier in the week. So basically, the forecast for
Thanksgiving holiday travel across western Montana and north
central Idaho has improved but the potential for wintry weather
still can`t be ruled out at this point.

&&

.AVIATION...Scattered low stratus and low-level haze with embedded
sprinkles and flurries will be present across the Northern Rockies
airspace through this evening (22/0300Z). Thereafter, snow and
wind will begin to impact the region, lowering ceiling, reducing
visibility at times in snow and blowing snow, and even contain a
few pockets of freezing rain. KSMN is the most likely terminal to
experience freezing rain (through 22/1200Z), however the
likelihood is fairly low. Otherwise and elsewhere, low
visibilities and low ceilings will be present at times through
22/1500Z. From here forward, low valleys will experience windier
conditions, combining with rising ceilings and fewer instances of
low visibility. Wind gusts to 30 knots will be present at times
at all area terminals throughout Saturday.

...Areas of freezing drizzle, rain and snow today...

...Mountain snow Friday night and Saturday...

.DISCUSSION...

Northwest Montana will continue in a wet and showery pattern
today with light snow, fog, and pockets of freezing drizzle
creating slick roads in spots. Elsewhere, some valley locations in
southwest Montana may be able to finally break the inversion
today. Those that do so could see 40s for highs for the first time
in a while.

A moist pacific system will move into north central Idaho and
western Montana beginning tonight and continuing through
Saturday. Here are several of the main impacts that are expected:

1 - Significant Mountain Snow...
Mountain passes such as Lookout, Lolo and Lost Trail could see 6
to 10 inches of snow by late Saturday. Expect periods of heavy
snow especially at Lookout and Lolo Pass with reduced visibility
starting Friday night through Saturday morning.

Other passes such as Marias, MacDonald, Homestake, Whitebird
Grade and Gilmore Summit could see 2 to 4 inches.

2 - Strong winds over the Camas Prairie..
Winds of 30 to 40 mph with gusts to 50 mph will be possible
starting Friday night through Saturday morning, especially from
Grangeville to White Bird Grade.

3 - Passage of strong cold front on Saturday...
Expect breezy westerly winds of 15-25 mph in valleys with 30 mph
gusts. Snow levels will also lower and most valleys should see a
rain/snow mix. No significant snow accumulations are expected for
the lower-elevation valleys. Higher-elevation valleys such as
Butte could see 1 to 2 inches on Saturday afternoon, with some
blowing snow lowering visibilities.

Another trough is expected to move through the Northern Rockies
Sunday into early Monday, bringing another round of rain and snow
to the area (although not as strong as Saturday`s system). This
storm looks to start out colder than the previous one, allowing
for lower snow levels and a mix of snow down to valley floors.
Some indicators in the forecast models are suggesting a chance of
snow bands setting up over western Montana Monday morning, which
could impact the morning commute for area cities. We will be
monitoring this potential the next few days.

Periods of precipitation will continue through at least the middle
of next week. It`s worth noting the the strong midweek winter
storm that has been advertised by the ECMWF forecast model for a
while has disappeared completely now, with a ridge of high
pressure in its place. This abrupt change indicates just how
uncertain the models are at this time. The bottom line is the
forecast for Thanksgiving holiday travel is not quite as
pessimistic as we thought, but there is still some potential for
winter weather, especially over the passes.

&&

.AVIATION... Freezing fog, areas of light snow, and pockets of
freezing drizzle will continue across northwest Montana through
at least this afternoon, affecting flying conditions at KGPI and
obscuring terrain. Some areas will not see any significant
improvement in flying conditions through Saturday as low clouds
linger. Elsewhere, KMSO and KSMN could see patchy fog and an
isolated shower this morning, while KBTM remains dry. All
terminals will be affected by a winter storm moving in late this
evening, which will bring widespread precipitation, lowering
ceilings, and increasing south winds.
