Area Forecast Discussion
National Weather Service Seattle WA
840 AM PDT Fri Oct 6 2017

.SYNOPSIS...An approaching front will spread clouds across Western
Washington late today, with some rain mainly tonight. Northwest flow
aloft will bring showers this weekend, especially in the mountains,
with the snow level 4000 to 5000 feet. A ridge will build over the
area for sunny weather Monday. An upper trough will approach the
region Wednesday and Thursday.

&&

.SHORT TERM...No changes to the forecast. Bands of high clouds are
moving through Western Washington this morning as a front approaches
from the northwest. The front will bring a little rain by the end of
the day - mainly on the coast, Olympics, north interior, and
Cascades. Much of the interior lowlands will have mostly to partly
sunny skies today, with clouds increasing late in the day. The front
will move through the forecast area tonight, and it will bring
measurable precipitation to most of Western Washington. The nearly
westerly flow aloft means the greater Seattle metropolitan area will
be strongly rain shadowed, and rainfall will probably amount to just
a few hundredths of an inch.

Cool, moist west to northwest flow will follow the front Saturday
and Saturday night. There will be showers especially at the coast,
along the west slopes of the mountains, and probably in the Puget
Sound convergence zone at times. But there will be sun breaks too,
especially in the interior lowlands. The snow level will be 4000 to
5000 feet, and showers should be heavy enough to give a few inches
of snow to the mountains.

Drying northerly flow will develop Sunday ahead of an approaching
upper ridge. Showers will become mainly limited to the Cascades
and then end in the afternoon. Sunday night should again be clear
and cool. McDonnal/Burke

.LONG TERM...Previous discussion...The upper ridge will progress
across the area Monday, for a sunny day. An upper trough will move
across the region Tuesday, but models differ considerably on its
strength. For now our forecast leans toward the GFS, which keeps
most of the precipitation associated with the trough over British
Columbia. The models are in rough agreement that a fairly deep upper
trough will dig south along the British Columbia Wednesday, moving
close to or over our forecast area on Thursday. McDonnal

&&

.AVIATION...Clouds will increase today with the combination
of onshore flow and a cold front nearing the area. Some areas of
rain will develop in the North Cascades and on the north coast and
Olympics this afternoon. There will be areas of rain tonight but
perhaps not so much in the lee of the Olympics around Puget Sound.
Still, cigs will fall and close in this afternoon and evening and
the mountains will become obscured.

KSEA...Increasing clouds and a little rain later today. A breezy SSW
wind will pick up through the afternoon hours.

&&

.MARINE...A front is moving down over the area from the northwest
today--and onshore flow has already increased and will continue to
increase through the afternoon. Strong onshore flow with the
front and behind the front on Saturday will keep small craft
advisories going coast and Strait. Onshore flow will ease on
Sunday and will become more northwesterly Sunday afternoon.
Northwest flow will continue Monday as high pressure builds offshore.

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...None.
PZ...Small Craft Advisory all waters except Admiralty Inlet.
