AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
231 PM PST Thu Feb 13 2014

.SYNOPSIS...
A series of storm systems will track across the region through
the middle of next week. Each delivers periods of rain and mainly
mountain snow. However there is the potential for snow in the
northern valleys during the night and early morning hours through
next Tuesday, then into all valleys by Wednesday. Some moderate
precipitation amounts are possible, along with breezy conditions.

&&

.DISCUSSION...
Tonight through Friday...Water vapor satellite shows an ominous
tropical moisture fetch heading towards the Inland Northwest. A
deepening surface low will deepen to around 973mb and track up
towards Central British Columbia which will direct this moisture
fetch into the Inland Northwest as a moist warm front tracks
through resulting in widespread precipitation.

For this evening a weak short wave ridge will move over the region
resulting in decreasing winds...and clearing skies. The westerly
upslope winds at 850mb will quickly shift to southeast near the
Cascades and southwest over the Idaho Panhandle which combined
with the short wave ridge will quickly result in showers coming to
an end. The clearing skies and somewhat drier air mass along with
winds quickly decreasing will for radiational cooling with low
temperatures expected to drop to near or below freezing for most
locations from I-90 northward. This will be important as the deep
slug of moisture comes up this way.

Precipitation looks to develop ahead of the warm front along the
East Slopes of the Cascades between 1am-4am...reaching Eastern
Washington by 7am...and finally into the Idaho Panhandle by 8 am.
Model wet bulb profiles suggest snow with the onset of
precipitation from Wenatchee to Wilbur to Spokane to Kellogg and
points north with valley rain/mountain snow south of these areas.
QPF totals through Friday morning show 0.5-1.25" for the East
Slopes of the Cascades (highest at the crest), around 0.5 inches
for the Blues, Palouse, and Central Panhandle Mountains, and
around 0.25 inches elsewhere. Based on these amounts will upgrade
the Winter Storm Watch to a warning for the East Slopes of the
Cascades, and put out a winter weather advisory above 1500 feet
for the Wenatchee area, Okanogan Valley, Waterville Plateau, and
the Okanogan Highlands. This is where low level upslope flow will
be maximized. Light accumulations will be possible below 1500 feet
but with marginal surface temperatures in guidance confidence is
highest above 1500 feet.  The Northeast Washington valleys and
North Idaho Panhandle may also flirt with advisory amounts but
models at this time show a marginal case for amounts greater than
2 inches.

Additional rain and wet snow for the Central Panhandle Mountains
along with snow melt Friday afternoon will result in additional
runoff and the areal flood warning has been expanded to include
Shoshone county. Meanwhile the flood warning for Lincoln, Spokane,
Kootenai, Benewah, Nez Perce, and Lewis counties has been
cancelled. In these areas either the low level snow pack has been
greatly diminished...or precipitation on Friday is not expected to
cause enough runoff for additional flooding. JW

Friday night through Sunday...Models are in good agreement in
continuing a cycle of endless waves and storms rotating around
broad Gulf of Alaska upper low and ejecting into western Canada
hustling another pacific moisture fetch ahead of them into the
Northwest US. The Friday storm detailed above will be exiting the
region with general residual orographic showers Friday evening. A
quiet break period under a intermission short wave ridge will
occur Saturday morning before the next storm system approaches
ginning up a warm front and a new moisture feed late Saturday
afternoon through Saturday night...with a minor follow-on wave
promoting continued showery conditions on Sunday.

The main issue of the forecast period will be the storm system
late Saturday through Sunday morning. Another deep Pacific
moisture feed enhancing on a warm frontal surface will ensure
high confidence of more precipitation. With the parent surface
low ejecting into Canada once again...snow levels should remain
generally above valley floors in the north and east mountain
valleys...with another good shot of accumulating snow above 3500
to 4000 feet in the mountains ringing the basin. Due to cold air
damming in the Cascades Lee this storm may bring moderate
accumulations to the east slopes Cascades valleys and the higher
basin terrain of the Waterville Plateau. Otherwise...expect
another general 1/2 to 3/4 of an inch of valley rain across the
eastern basin and northeast mountains. It is with this storm that
there is a potential for snow melt/rain small stream flooding
concerns in the northeastern mountain zones...but this possibility
is still rather nebulous and uncertain and will be refined in later
cycles. /Fugazzi

Sunday night through Thursday...Very cluttered and dynamic
forecast interval continuing on with the parade of very strong
weather systems with effective taps into subtropical moisture
passing through the region. Snow levels will oscillate along with
the greater spread of forecast temperatures and with overnight
lows not dropping too far below freezing until Wednesday. The
expectation is that snow-melt will continue for much of the
interval followed by moments of the slush water freezing on
surfaces during the late overnight and early morning hours.
Significant wet low pressure features include one passing through
Sunday night/Monday. The long-wave pattern then gets to be more
trof like with the jet stream remaining south of the forecast area
from about Tuesday night on through the remainder of the workweek.
This would allow any weather disturbances passing through to
utilize the cold conditionally unstable air-mass on the north side
of the jet stream to allow more effective radiational cooling at
night and increase the snow ratios of snow to water...which makes
the snow more less wet and more powdery. A system passing through
Tuesday will start this out with lowering of snow levels and
cooling so lowland elevations will see less melting and a return
to a rain/snow mix potential transitioning to just snow with yet
another system passing through Wednesday. Thursday has the most
instability and cooling as the jet stream is the furthest south
and as such the cold conditionally unstable air-mass is better
positioned overhead of Eastern Washington and Northern Idaho yet
the models are void of depicting significant shortwaves passing
through then so pops drop off a bit in comparison to the
remainder of the forecast, but it should be noted that small
mesoscale disturbances with enough forcing could produce very
large yet localized snow amounts Thursday so nobody is saying it
will be a dry day everywhere. Additionally since the sun is getting so
much higher on the horizon the expectation is the freeze/thaw
cycle of snow/water on ground will really start happening then
too. /Pelatti

&&

.AVIATION...
18Z TAFS: Post frontal conditions today will result in clouds banked
up into the Cascades and Idaho Panhandle with a few stratocumulus
clouds over KPUW/KSFF/KGEG/KCOE.  Strong winds aloft will lead to
breezy to windy conditions at the TAF sites through the afternoon.
These winds will rapidly die down between 23z-02z as mixing and
winds aloft decrease. Our next system will roll in tonight with
precipitation crossing the Cascades 9-12z and then into Eastern
Washington/North Idaho 13z-18z.  A mix of precip types is expected
with KEAT likely seeing the lowest CIGS and visibilities with snow
and IFR conditions.  But all TAF sites will see a rapid deterioration
of surface conditions after precip develops except KLWS where CIGS
may stay VFR with stronger downslope flow off the mountains.  JW
