Area Forecast Discussion
National Weather Service Spokane WA
348 AM PST WED DEC 16 2015

.SYNOPSIS...
A dry and seasonably cool break in the weather will envelop the
region today and tonight. A strong Pacific storm system will
spread snow over the region Thursday and Thursday night with many
locations experiencing a messy wintry mix of precipitation into
Friday. An active and wintry weather period will persist through
the weekend.

&&

.DISCUSSION...
Today...An upper level short wave driving a surface cold front
from the north is passing through the region early this morning
with radar indicating widespread light to occasionally moderate
snow across the eastern third of Washington and the Idaho
Panhandle. Current Winter Weather Advisories will be expanded to
include the Spokane area due to intensity of snow over the next
couple hours likely overwhelming the specific heat capacity of the
road surface and causing a layer of ice to form under subsequent
snow...even though it is expected that snow will be tapering off
during the commute period.

After 7am or so the main snow region will impact the Palouse and
points southward while the northern zones become locally breezy
with a biting north wind heralding dry Canadian Polar air. The
remainder of the day will be raw but probably feature increasing
sunshine as the dry push evaporates lingering clouds from north to
south through the day.

Tonight will be another dry break period between storm systems
with decreasing winds as the pressure gradient relaxes and high
pressure becomes established over the spine of Idaho. Low clouds
and fog will probably develop over much of the fresh snow covered
region as winds drop off tonight and temperatures plunge at least
initially before increasing high clouds from the next system
inhibit radiational cooling later tonight.

Thursday will be a day of general deterioration from west to east
as the next incoming system digs an incipient warm front along the
Washington/Oregon border with increasingly moist isentropic ascent
over Washington north of this warm front. The air mass will be
cold enough for an onset of snow at all locations...even the deep
basin...by afternoon in the Cascades and western zones and
possibly over the southeast zones by late afternoon. The
northeastern portion of the forecast area will probably only
experience thickening and lowering clouds as the top-down
moistening process commences in earnest. /Fugazzi

...MIX OF SNOW AND FREEZING RAIN POSSIBLE THURSDAY NIGHT INTO
FRIDAY MORNING...

Thursday night through Saturday...A strong warm front will
bring precipitation to the Inland Northwest starting at the
Cascade crest early Thursday then spreading to the rest of the
forecast area Thursday night. Confidence is increasing that
precipitation will start as snow but change over to a mix of
rain, sleet and freezing rain for the area from Leavenworth to
Wenatchee to Moses Lake Thursday night then spreading north and
east to include the Waterville Plateau, Spokane-CdA areas and the
Palouse Friday morning. This will make for a very messy morning
commute.

Areas that receive mostly snow could receive 2 to 5 inches in
the valleys with 6 to 10 inches for the mountains in the eastern
half of the forecast area. The Cascades will be another story.
This is where heavy snow will fall with 6 to 12 inches in the
valleys with 1 to 2 feet possible in the mountains.

Confidence is high enough to hoist a Winter Storm Watch for the
East Slopes of the Cascades, Wenatchee Area and Waterville
Plateau for Thursday morning through Friday morning. This will be
not only for heavy snow but also for up to a tenth of an inch of
freezing rain. Highlights will be limited to the western zones,
since there are Winter Weather Advisories currently in effect for
some of the eastern zones. These will be addressed by the day
shift once current highlights end.

Once the cold front arrives Friday afternoon, steady precipitation
will become more showery in nature and westerly flow will
provide somewhat of a precip shadow for the east slopes. The
upper trough passage will provide adequate instability to keep
scattered snow/rain showers going through Saturday but additional
snowfall accumulation will be light.

Saturday night through Tuesday...No changes made to this portion
of the forecast. Northwest flow will bring colder conditions as
a couple of weather systems roll through the region. Precipitation
will fall mainly in the form of snow except for the lowest valleys.
The progressive nature of these storms should keep snowfall
amounts rather light. /Kelch

&&

.AVIATION...
12Z TAFS: A weak surface low pressure over eastern WA at 12Z is
promoting areas of IFR and local LIFR conditions in -SN st the
KGEG area TAF sites and KPUW. KLWS will deteriorate to MVFR
conditions in -SN this morning as well. The surface low will move
east into the Idaho Panhandle by 18Z and out of the region by 00Z
Thursday. A dry cold front descending from north to south through
the region will bring sharp improvement to all TAF sites between
18Z and 21Z today as dry continental air invades the area from
Canada. A moist boundary layer will promote a return of IFR and
LIFR stratus after 06Z tonight to the KGEG area TAF sites.
Easterly winds at KPUW and KLWS will promote downslope drying at
these TAF sites for a minimal chance of stratus. KMWH and KEAT are
on the far western edge of today's precipitation shield and
should remain mostly VFR after a small threat of snow showers
before 15Z today. /MJF
