Area Forecast Discussion
National Weather Service Seattle WA
300 AM PST Wed Nov 22 2017

.SYNOPSIS...An unseasonably warm moist air flow will continue into
Thursday morning before the frontal system moves inland. Though the
rain will ease today, this system will bring more rain to Western
Washington tonight before turning to showers with cooler air
Thursday. After another break on Friday, another weather system is
expected to arrive Saturday afternoon and night with another system
arriving Sunday night.

&&

.SHORT TERM...Water Vapor and IR satellite imagery continues to show
a long fetch of warm moist air extending from well east of the
Hawaiian Islands northward into the Pacific Northwest east of the
elongated upper trough near 145W. Following the warm front Tuesday,
the air mass over Western Washington was quite mild and muggy with
temperatures and dewpoints both in the 50s early this morning.

Doppler weather radar showed the rain eased overnight as anticipated
with the relative break in the rain continuing today. May break a
few record highs today in this warm air mass and some record warm
lows may fall as well. Snow levels to also remain above 8000 ft
today.

The next shortwave rounding the offshore upper trough should engage
the warm moist southerly flow to generate another surge of rain
tonight and progs concur. Rain amounts should be less than what fell
Tuesday - about 2-4 inches in the Olympics, 1.5-3.5 inches in the
Cascades and about a half to 1.5 inches in the lowlands. See the
hydro section below for more on the flood situation and refer to the
latest flood bulletins for current river information.

Soil conditions to remain moist. Will continue the heightened
landslide threat special statement.

The frontal system is expected to move onshore and inland Thursday
bringing a cooler air mass and turning the rain to showers. Snow
levels should fall close to 4000 ft by late Thursday. The showery
pattern should continue into Friday with cooler more seasonable high
temperatures. Buehner

.LONG TERM...The guidance is in rather good agreement with the
overall pattern into early next week. The next digging upper trough
well offshore should send another surge of warm moist air and rain
NE through the region Saturday with the front moving inland Saturday
night. Snow levels will pop up again in the 5000 to 7000 ft range
before dropping again behind the front Sunday around 4000 ft for
those returning across the Cascades from the holiday. The progs do
differ on the front's associated surface low. But given the vertical
stacked nature, the low should weaken as it moves inland. Guidance
is implying more ridging aloft and a more zonal flow pattern for a
decrease in the precipitation early next week. Buehner

&&

.AVIATION...Moist southwest flow aloft will continue through
Thursday. At the surface, southeasterly pressure gradients will
prevail. Strong south to southwest winds 35 to 50 kt will continue
at times between 030 and 050 through Thursday.

An area of showers north of a line from near KUIL ESE to KSEA is
lifting north while widely scattered showers are seen south of that
line. The air mass across the area has originated near Hawaii and is
quite moisture laden. Hence ceilings are quite variable with VFR
conditions seen between showers, and LIFR conditions are seen where
flow is upslope or around heavier showers. Visibilities are
occasionally falling below 2SM in the heavier showers. Overall,
expect conditions to improve somewhat this afternoon and some
clearing at times may occur to the lee of the Olympics as strong SSW
flow aloft interacts with the terrain. Rain showers will increase
and conditions will deteriorate after 03Z this evening as a frontal
system offshore approaches. Albrecht

KSEA...Conditions have improved to VFR early this morning, but any
showers passing the area will possibly lower cigs to 015, especially
this morning. Conditions will become mainly MVFR this evening in
precipitation and lower ceilings as the front offshore approaches.
Southeast winds 5-8 kt this morning will become southerly 10-14 kt
this afternoon and tonight. Winds aloft will be strong at
times...over 50 knots at 5000 feet. Albrecht

&&

.MARINE...A frontal system will approach the waters from the west
this afternoon then move inland late tonight. The front will be
followed by a trough of low pressure on Thursday. Expect Small craft
advisory conditions for most of the waters today except for Puget
Sound and the central portions of the Strait of Juan de Fuca.

Southwest winds will continue on Thursday as the trough of low
pressure moves across the waters. Most waters, including the Puget
Sound and Hood Canal will likely see Small Craft Advisory conditions
on Thursday.

Another system will arrive on Saturday. The 06Z GFS brings the
system through the interior of Western Washington as an open wave
while the preferred ECMWF and Canadian model solutions deepen a low
to below 980 mb as it lifts northward through the offshore waters.
The preferred solutions would result in gales over most waters with
small craft advisory conditions over Puget Sound and Hood Canal.
Albrecht

&&

.HYDROLOGY...Several Western Washington rivers are above flood
stage early this morning, and a few more are probably going to rise
above flood stage today. As of day break flood warnings are likely
to be in effect for the Satsop, Skokomish, Cowlitz, White,
Snoqualmie, Skykomish, Snohomish, and Stillaguamish Rivers. Most
rivers will produce minor flooding, but a few could reach the
moderate category.

Warnings and watches change as needed. For the current list, please
check: www.wrh.noaa.gov/sew/get.php?pil=RVA&sid=SEW

Rainfall over Western Washington began decreasing late Tuesday
evening, and the upper reaches of the rivers starting cresting
overnight. The crests will be moving downstream today and tonight,
but additional rain from the next front tonight and Thursday could
push rivers higher.

Precipitation from the Tuesday/Tuesday night system amounted to
generally 2 to 5.5 inches over the Olympic Mountains and 1 to 4
inches over the Cascades, while the snow level was around 9000 feet.
There will be some more precipitation today with the snow level
around 7500 feet, but it will be - relatively speaking - a break
between systems. The next front will move through tonight and
Thanksgiving Day, with a forecast of generally 2 to 4 inches over
the Olympics and 1.5 to 3.5 inches over the Cascades. The snow level
will be around 7500 feet as this system arrives, falling to 4000
feet late Thursday as precipitation decreases.

With this second round of rainfall tonight and Thursday, there is a
possibility that flooding will become more widespread and/or
prolonged. Northwest River Forecast Center models show that flooding
could develop on reaches of the Nisqually, Skagit, and Nooksack
Rivers. There is at least a minor threat that any flood-prone river
in our area reaching flood stage.

In addition, there is a threat of landslides across the lowlands of
Western Washington. The USGS landslide guidance shows one or two
stations near or just above the threshold of concern, and additional
rain through Thursday will drive those numbers higher.
