.SYNOPSIS...Two frontal systems in quick succession will bring
wet and windy weather to Western Washington tonight through
Thursday night, with snow in the mountains. There will be a break
in the weather Friday, with an upper trough bringing more rain and
mountain snow Saturday. Another break in the weather is likely Sunday,
with the next front bring more wet weather Sunday night and Monday.

&&

.SHORT TERM...Rain is spreading into Western Washington this
evening, ahead of the warm front of a vigorous Pacific frontal
system. South to southeast winds were also rising across the
forecast area, with winds gusting to 35 to 45 mph at 9 pm in the
north interior.

The warm front is still offshore this evening, but it will move
northeast across Western Washington tonight. The heaviest
precipitation amounts will be at the coast and especially over the
Olympic Mountains -- no surprise with 850 mb southwest winds
peaking near 60 kt as the warm front arrives later tonight. The
winds at the surface will also peak late tonight, and the
strongest winds should be in the northwest interior of Western
Washington. Winds there should locally reach 20 to 35 mph
sustained with gusts 45 to 55 mph, and a wind advisory remains in
effect through 10 am Thanksgiving Day.

The cold front will follow the warm front Thanksgiving Day, moving
through from the west. It will bring more rain and mountain snow
through the day, but winds should ease by late morning. Another
small frontal system is forecast to develop quickly late
Thanksgiving Day in the pool of cool air offshore, then move
through northeast across Western Washington Thursday night.

The most interesting thing about this system is its potential to
produce windy conditions. Specifically, the GFS model is
forecasting a surface low to develop and track northeast from the
central Washington coast late Thursday evening across the north
Puget Sound region shortly after midnight and then into southwest
British Columbia late Thursday night. The low is only forecast to
bottom out around 999 mb, with a south to north pressure
difference near 13 mb across the Western Washington interior. All
other models have been consistently depicting this as a much
weaker feature, with the pressure difference peaking around 8 or 9
mb. Bottom line is it will be windy, but there is considerable
uncertainty. Most likely we will see another round of wind
advisory level winds at the coast and in the interior from around
Everett northward -- again, 20 to 35 mph with gusts 45 to 55. If
the GFS turns out to be the most accurate model, then the winds
will be more widespread into the Puget Sound region and southwest
interior, and locally high wind is possible.

Total rainfall for tonight through Thursday night should be 1.5 to
3.o inches at the coast, with 0.5 to 2.0 inches in the interior
lowlands. The Olympics and Mt Baker and Mt Rainier should get 2 to
4 inches of precipitation, with generally 1 to 2.5 inches
elsewhere in the Cascades. The snow level will 2500 to 3000 ft, so
all the highway passes -- including Snoqualmie Pass -- will get
snow. A winter storm warning is in effect for Thanksgiving Day
with a winter storm watch for Thanksgiving night.

There will be a break in the weather Friday through Friday
evening. The best chance for some precipitation will be at the
coast and in the Olympics, but little if any precipitation will
fall over the Western Washington interior and in the Cascades. The
next front will move in from the southwest late Friday night and
move across the area Saturday. McDonnal

.LONG TERM...Here is the long term section from the afternoon
forecast discussion -- The models are showing a break in the
pattern as we move into Sunday. By then a ridge will nudge inland
but cool, northerly flow will cut temps a few degrees. This break
will be short lived as the next system arrives Sunday night. This
upper level short wave trough may bring another round of heavy
snow to the mountains...with snow levels still around 3000 feet.
After another break on Tuesday, more wet weather is in store
Tuesday night into Wednesday. 33

.AVIATION...A frontal system is moving through Western Washington
tonight. There is strong southwesterly flow aloft. The air is moist
and stable then will become unstable behind the front after about
daybreak on Thursday as the rain turns to showers.

KSEA...Rainy tonight with fairly strong southerly winds aloft.
A breezy southerly surface wind will develop overnight as well.
The rain overnight should turn to showers with a frontal passage
around daybreak and then another frontal wave should turn the
showers back to rain late in the afternoon or evening Thursday.

&&

.MARINE...A strong frontal system tonight should be followed by
another frontal wave Thursday night and there are some gale warnings
up for this first system. The rain overnight will give way to breezy
showery weather on Thursday, and then another frontal wave will
probably arrive early Thursday evening.

&&

.HYDROLOGY...Additional rains from another front tonight and
Thanksgiving Day will likely push the Skokomish above flood
stage. A flood watch is in effect.

Elsewhere, flooding is not expected during the next 7 days.
