AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
230 PM PST Mon Feb 20 2012

.SYNOPSIS...
A series of quick moving weather systems will continue to bring
damp...cool and occasionally windy weather for much of the week.
A return to winter-like cold and snowy conditions are possible by
this weekend.

&&

.DISCUSSION...
Tonight and Tuesday: With an upper level ridge anchored in the
eastern Pacific, the Inland NW will be under the influence of a
moist northwest flow with embedded disturbances passing through
the region. One of these disturbances, a weak warm front, will be
exiting north Idaho early this evening, allowing the coverage of
snow showers to temporarily decrease this evening. Additional snow
accumulations will be light and will be found mainly above 3k ft.
Despite the northwest orientation of the flow, temperatures will
be warming as 850mb temperatures increase and isentropic lift
spans across much of northeast Washington and north Idaho. As seen
on satellite, an area of low pressure will be moving across
northern British Columbia and forecast to swing southeast toward
the Canadian border overnight. This will prompt a second weak
warm front to move across region late tonight into Tuesday
morning. With the orographic flow hitting the Cascades, expect the
heaviest amounts of precipitation along the Cascade crest along
with the mountains of northeast Washington and much of the
Panhandle. Snow levels will dip slightly overnight to 2-3k ft, but
will be on a steadily increase through the day on Tuesday, rising
to 5-6k ft by afternoon. Morning snow accumulations will range
from 2-4 inches. But much of the mountain precipitation will
change to rain except for the highest elevations. Due the
expected warming, no significant snow event is expected tonight
into Tuesday and no winter highlights anticipated. Yet with the
warming and rain falling on snow, this may lead to a ripening of
the snow pack and possible higher than normal runoff on the area
rivers like the Wenatchee and Stehekin. This will be monitored in the
coming shifts. Meanwhile, winds will steadily increase on Tuesday
as the area of low pressure tracks across southern British
Columbia and begins to tighten pressure gradients across the
region. Tended to lean toward the GFS and expect westerly winds
to become breezy by Tuesday afternoon with speeds of 15-25 mph and
higher gusts possible in exposed areas. Although the NAM has
stronger winds and a more pronounced slop-over across the Cascade
crest by late Tuesday afternoon. The warming will translate to
above normal temperatures by Tuesday afternoon, mid 40s to mid
50s! /rfox.

...Strong wind event possible Tuesday night and Wednesday...

Tuesday night through Thursday...This period will be potentially very
windy and unsettled. Models are in reasonable agreement regarding
the overall field of motion...and depict a pattern that is rather
ominous from a wind standpoint. First...on Tuesday night a very
deep fetch of Pacific Moisture will be zonally well oriented into
the forecast area. The overall flow regime will be becoming fast
and zonal so the main precipitation threat will be along the
Cascades and over the orographically favorable Idaho Panhandle
Mountains...although a stray shower is possible anywhere east of a
line from Omak to Pullman during the best moisture orientation on
Tuesday night. Snow levels will be rather high...with snow limited
mostly above 4000 feet...but heavy amounts may fall on the higher
peaks above the population density so no snow highlights will be
issued for this event.

The main story is likely to be the winds. On Tuesday night there
is increasing confidence of a strong downslope potential in the
Wenatchee area and the deep basin zones as a cold front crests the
Cascades early in the evening and very strong cold air advection
invades over the crest. Model soundings...both NAM and GFS suggest
a stable layer just above the surface over the Cascade Crest which
will assist in funneling and squeezing strong laminar flow across
the crest and down the lee side into these zones. The main
question will be if and how early the near surface layer will be
mixed out allowing the winds to surface in the lower elevations.
In any event confidence is high that the higher benches around
Wenatchee and the normally windy spots near Vantage and the
Waterville Plateau will receive strong gusts Tuesday night. A High
Wind Watch will be issued with the afternoon package to begin
highlighting this potential.

During the day Wednesday the wind threat will broaden out to
encompass the entire basin...with models indicating strong
cyclogenesis in the lee of the Rockies which will dramatically
tighten the southeast pressure gradient across the basin. This is a
recognized pattern for strong wind issues...and the Watch will be
expanded to include the eastern basin starting Wednesday morning.
While the Gradient as presently forecast suggest sustained winds
in the 25 to 35 mph range...gust potential from mixing may allow
gusts as high as 50 or 60 mph on exposed terrain over the eastern
basin...with even stronger gusts in the mountains. This situation
will need to be monitored and the forecast refined on subsequent
shifts...but the current confidence level of the threat does make
a High Wind Watch warranted at this time.

Wednesday night and Thursday will allow a slow improvement to
merely breezy conditions with continued lingering showers over the
orographically favorable terrain...with snow levels plunging to
the surface even in the lowest valleys. /Fugazzi

...Much cooler temperatures and potential for significant valley
snow Friday through the start of next week...

Thursday night through Tuesday: A drastic shift in the jet stream
is looking more and more apparent as each of the ensemble means
generated from the GFS/ECMWF indicate a rex-block of sorts along
160W with the northern branch ridge driving a cold deep upper-
level trough into the Pac NW over the period. While the ensembles
and operational models show agreement with the cooler pattern in
store, there are considerable differences noted with the embedded
shortwaves, specifically, the timing of the initial cold front,
track of the surface low, and placement of a lingering TROWAL
airstream (ie snow axis) within the post-frontal air mass. So
while our confidence is increasing for a dip in the temperatures
and likelihood for valley locations to experience a significant
snow; there is generally little to no forecast confidence where to
place the highest PoPs and snow amounts. Utilizing a blend of all
guidance has resulted in only minor adjustments until confidence
increases.

Cool northwesterly flow over the region Thursday evening will
slowly weaken as a deepening surface low tracks along 50N and
nears the Pac NW coastline early Friday morning. A warm front will
be aimed into the region with increasing moist, isentropic ascent
and light stratiform pcpn. There is very little argument amongst
the models that moisture will be hard to come by as the wave
initially tracks along and taps into a very juicy moisture fetch
consisting of precipitable water values in excess of 1.00".
However, this is where details begin to waver. Pending how deep
this initial surface low becomes upon reaching the coast and which
track it takes (WA or southern BC) will have enormous impacts on
strength of the warm sector pcpn rates/snow levels before the
parent upper-level trough drops south and cooler air begins to
flood into the region late Friday/early Saturday.

As the initial wave of energy along the leading edge of the
midlevel trough ejects E into the Intermountain West, an
elongated pressure trough or area of converging wind fields
remain strung across the Inland NW within a region of higher
theta-E air within the sfc-700mb layer associated with a lingering
TROWAL. Meanwhile, upper-levels will continue to cool with 500mb
temperatures expected to cool between -30 to -35C. All things
considered, and low-level convergence will be centered under
increasing midlevel instability and the potential for moderate to
heavy snow bands will be a big concern with snow levels sitting on
most valley floors. It is the placement and residence time of this
feature that models are struggling with...offering very little
confidence who will see the best snow.

The midlevel trough continues to dig in the SW Conus Sunday and
Monday with drier, polar air expected to spill into the Inland NW
from the north and northeast. Any lingering snow showers will
slowly come to an end from north to south with the highest Pops
centered over the Camas Prairie and Blue Mtns. North to northeast
pressure gradients will be on the increase as the polar surface
high slides down western Canada. Gusty north winds expected for
the Okanogan Valley...Waterville...and into the western Basin.
Further east, northeasterly winds will channel down the Purcell
Trench and into the West Plains. If we receive any appreciable
snow prior to the cooler temperatures and gusty winds
Sunday/Monday, blowing snow will become an additional concern. /sb

&&

.AVIATION...
18Z TAFS: The passage of a weak shortwave enhanced by low level
warm air advection will keep the threat of a light rain snow mix
for many of the TAF sites through the afternoon. Satellite and
radar show the back edge of the band of the precipitation has
