AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
235 PM PST Thu Dec 19 2013

.SYNOPSIS...
The break in active weather will come to an after tonight as a
much stronger winter storm system moves in for Friday. This system
will likely deliver the heaviest snows so far this season to many
valley locations. The heaviest snows are expected to fall over
southeast Washington and the central Idaho Panhandle. The impacts
of this storm will generally wane by Saturday except for residual
mountain snow showers. Another significant storm will move into
the area on Monday, but with milder valley temperatures.

&&

.DISCUSSION...
Tonight through Friday night...Satellite indicates an incoming
weather maker for the region as a mass of clouds cresting the
upstream ridge and barreling toward the forecast area out of the
northwest. The precipitation producing frontal region is currently
nearing the Queen Charlotte island and will take most of tonight
to approach the forecast area. In the mean time increasing high
and mid level clouds will invade the region but the low level air
mass is way too dry to allow any precipitation to reach the
surface other than the highest peaks before tomorrow. Thus tonight
will be dry but cloudy...and this cloud cover will assist in
preventing temperatures from dropping as low as the dew points
would suggest is possible.

WIDESPREAD ACCUMULATING SNOW ON FRIDAY AND FRIDAY NIGHT

Overview...This will be the first widespread significantly
accumulating snow event in a while for the region. Character of
this storm will be sustained isentropic ascent on a warm front fed
by a deep and well directed fetch of precipitable water. Unlike
normal transiting fronts...this front will largely stall on a line
from about Vancouver,BC to Pendleton,Oregon during the day
tomorrow and promote a sustained period of light to moderate snow
mainly over the eastern half of the forecast area. The feeding
moisture fetch will become directed into the Palouse and points
southward during the day and this region stands to see the highest
accumulations. Snow will decrease from north to south starting Friday
evening as the moisture feed becomes more directed into Oregon
than Washington. With surface dew points in the teens or even
single digits while the air mass moistens up tonight from top to
bottom...wet bulb cooling will promote all snow everywhere by the
time of onset. There is a small chance that Lewiston may mix with
some rain or possibly freezing rain late Friday afternoon...but
essentially this will be a snow storm for the entire forecast
area.

Regional Details...
Deep basin and Cascades...These zones will experience some
accumulations from this event as the initial warm front passes
through before stalling. With mid level northwesterly flow precipitation
shadowing in the Cascades lee is expected after Friday
morning...but slop-over will continue through the day near the
Cascade Crest. A Winter Weather Advisory will be issued for
travelers heading up to the passes. The Wenatchee-Omak-Moses Lake
region will probably escape with minor accumulations to an inch or
so of snow falling during the morning hours.

Mountains/valleys north of the basin and the Spokane/CD'A
area...Beginning in the mid-late morning hours and continuing
into the early evening hours a sustained period of light to
occasionally moderate intensity snow will occur. Confidence is
high that this will be a widespread 2 to 4 inches event in the
valleys and northeast basin and will likely impact the Friday
evening commute period. Mountain peaks will see more snow but not
enough to justify a WSW. Snow will taper off during the late
afternoon in the northern valleys and early evening in the
Spokane/CD'A area. Winter Weather Advisories will be issued for
these areas.

Palouse and Shoshone County Mountains...These regions will bear
the brunt of this storm's unpleasantness. Sustained and
aggressive moist isentropic ascent over the Palouse...aggravated
by good and direct orographic ascent into the Central Panhandle
Mountains will assure Heavy Snow Criteria accumulations starting
late morning/early afternoon and lasting through much of Friday night.
Winds are not expected to be a significant factor so the particularly
menacing Palouse hazard of blowing and drifting snow should be
sparse and limited.

L-C Valley...This will be a snow storm even in the Lewiston
area...however accumulations will be limited by a higher
snow/water ratio in this low elevation valley. There is some
uncertainty as to whether snow may mix with rain in the late
afternoon or even if some freezing rain may sneak in if the warm
front wanders a bit closer to this area. Subsequent shifts will
need to watch this potential and further refine the forecast. This
is the area of most uncertainty with this storm.

Camas Prairie and Blue Mountains...Heavy snow is likely in the
Blues with good moisture feed and Orographic ascent. The Camas
offers a more challenging problem...with the mid level flow
possibly leading to a precipitation shadow...or at least a reduced
accumulation potential in the lee of the Blue Mountains. Flow does
not become appreciably northwest...which is very favorable for heavy
snow...until late in the event. Thus have opted to go with a
high end Advisory rather than a Warning...but this will also have
to be monitored as the situation develops. /Fugazzi

Saturday through Sunday night...The Inland Northwest will be on the
back end of the strong storm system, with precipitation chances
tapering off over SE Washington and the central and southern Idaho
panhandle. The ridge of high pressure will slowly push inland, but
general northwest flow will continue through Saturday and early
Sunday. Light precipitation will continue in the favored upslope
regions, mainly in the Idaho panhandle. Amounts should remain
light and confined to the higher elevations. During the day on
Sunday, the flow begins to back toward the west and then
southwest, a warm front will push toward the northeast. Snow
levels will be on the rise through Sunday night from south to
north, which will transition any light snow that has developed to
light rain or a rain/snow mix. ty

Monday through Thursday: The longwave pressure pattern will change
little through next week. We will see another shortwave trough
ride over the ridge of higher pressure in the eastern Pacific.
This shortwave is considerably deep enough that I do think it will
give the region another decent shot at some precipitation across
the region. There are some model differences that revolve around timing
and precip amounts. The ECMWF is a nice compromise between the
Canadian and GFS solutions. The Canadian solution is clearly the
strongest of the three and is a bit faster than the GFS. The ECMWF
solution generally matches the strength of the GFS, but is also a
bit faster like the Canadian solution. Highest confidence of
precip, with more weight toward the ECMWF, is expected during the
day on Monday. All the models show a fairly quick hitter with a
relatively short duration of moist isentropic ascent in the warm
sector follow by the cold front in the afternoon. Showers are
expected to linger in the ID Panhandle through Monday night/Tuesday morning.

Snow levels are a little tricky with this system as models show a
more mild and moist low level profile unlike the colder and drier
air mass in place before Friday's storm system. This should
result in rain for the Spokane/Coeur d'Alene areas, the Palouse
and L-C Valley. A pronounced rain shadow in the lee of the
Cascades will keep much of this area dry. The far northern
valleys will have a better chance of seeing mixed precip in the
form of rain and snow. If this system decides to push in earlier
around Monday morning, then snow would be more likely. 850 mb
winds with the front will be up around 30-40 kts. An afternoon
cold front passage would give us our best chances for mixing.
Thus, we could see some breezy winds with this storms system
during the afternoon and evening hours.

Weather conditions dry out behind this system for mid week as
shortwave ridging moves in on its heals. The eastern Pacific
longwave ridge of higher pressure also looks to shift slightly more
eastward. This would take any shortwave impulses north and east of
the region.

Temperatures will be at their warmest on Monday with highs around 5
degrees above normal. We will then see a cooling trend into mid
week as drier polar continental air filters in behind the cold
front. Clear skies will promote good radiational cooling and high
pressure will result in increasingly stagnant weather conditions.
Developing stratus and fog will become increasingly more likely as
well toward the latter half of the work week. /SVH

&&

.AVIATION...
18z TAFS...A dry low level air mass has invaded the region
overnight with no fog or stratus expected at any TAF sites through
today and most of tonight...just increasing high altitude cirrus
as the next storm system approaches. This incoming storm will
bring a chance of MVFR or high IFR ceilings and vis in snow to the
KEAT and KMWH TAF sites after 12Z Friday...and conditions will
deteriorate to IFR conditions in snow over the eastern TAF sites
around the end of the TAF period at 18Z. /MJF
