.SYNOPSIS...
Weak upper level trough tonight will move east Sunday. Weak
upper level ridging Sunday and Monday before shifting eastward
Tuesday. Another upper level trough will move over Western
Washington Wednesday and remain through the end of the week.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
Weak upper-level troughing tonight with continued low-level
onshore flow. Areas of marine stratus looks to develop into the
early morning hours on Sunday. Surface winds are favored to
become light - but gusts upwards of 15 to 20 mph are possible
for Whidbey Island after midnight. Overnight lows are forecast
to fall into the mid 40s to mid 50s.

The aforementioned upper-trough will push east of the Cascades
on Sunday. As a result, weak ridging looks to replace it Sunday
into Monday. Afternoon highs are forecast around seasonal
averages on Sunday with values in the 70s to near 80 F
throughout the lowlands. Coastal areas will likely remain in the
60s. A noticeable warm is in the offing on Monday with forecast
highs 5-8 degrees above normal. Temperatures ranging between
the upper 70s to mid 80s. The coast remaining the cool spot
again, with highs in the 60s. Overnight lows are forecast in the
upper 40s to mid 50s for both Sunday night and Monday night.
Upper-level ridge favored to move east by Monday evening.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
An upper level trough and associated front will approach the
coast Tuesday. Increasing onshore flow during the day Tuesday
will drop highs in the interior back into the 70s. Highs on the
coast in the lower to mid 60s. Upper level trough and
associated front moving through Wednesday for mostly cloudy
skies and increased PoPs for most of the area. Highest
probability for measurable precipitation appears to be over the
North Cascades at this time. Highs continue to cool with 60s
and lower 70s in the forecast. Weak upper level trough hanging
around Wednesday night through the end of the week. Low level
onshore flow making for a morning clouds afternoon sunshine
scenario Thursday through Saturday. Highs remaining near or a
couple of degrees below normal, in the upper 60s to mid 70s over
the interior and mid 60s on the coast.

.AVIATION...
Mostly clear/VFR conditions this evening as a cold front will
pass through dry. Low clouds will return tonight, with the
highest chances near the coast, and a 30-40% chance of it making
it into Puget Sound. MVFR is the favored ceiling category, with
timing between 12-18Z in the morning (coastal areas will see it
begin a few hours earlier and hold a couple hours after). West
to northwest winds will be the dominant direction through the
TAF period. Strong onshore flow this evening along the Strait of
Juan de Fuca with gusts to 20 kt possible through Sunday
morning. This will result in northwesterly winds spilling into
Puget Sound terminals this evening, then shifting northeasterly
with gusts to 15-20 kt through early Sunday morning.

KSEA...VFR through the evening. Stratus returns Sunday morning
with a 30-40% chance the ceilings will be in the MVFR category
between 12-18Z. Winds northwest to northeast overnight 7-10 kt
gusting to 15-20 kt through the evening, shifting back to the
northwest during the day Sunday. Few gusts to 20 kt possible in
the afternoon.

AH/HPR

.MARINE...
A rather stagnant weather pattern will persist over Washington`s
waters into next week. Broad high pressure over the northeast
Pacific and lower pressure inland will keep an onshore flow pattern.
This will result in increased westerlies through the Strait of Juan
de Fuca each evening, some having the potential to reach small craft
thresholds. There is high confidence (greater than 70%) for strong
westerlies this evening through the Strait. Guidance also suggests
there is a 70% chance or higher for small craft winds to reach
Admiralty Inlet this evening as well. Therefore, small craft
advisories are set to go into effect the Central/East Strait and
Admiralty Inlet later this evening. Winds will also increase for the
lower coastal waters late this evening to advisory thresholds. There
is high confidence (75-85%) for increased northwesterly winds Sunday
evening across all portions of the coastal waters, and the advisory
has been extended. Long term guidance highlights a 60-90% chance for
small craft winds through the Strait next week, likely requiring
additional headlines. A few weak fronts will move through the waters
throughout the week, but high pressure is expected to rebuild
quickly over the waters behind the fronts.

Seas will build late this evening to 6-8 ft and up to 10 ft through
Monday. Seas will gradually subside below 10 ft on Tuesday to 4-6
ft.

&&

.FIRE WEATHER...
Continued low-level onshore flow well into next week. This will
keep good overnight relative humidity recoveries in the
forecast and help subdue fire weather concerns despite the
warmer temperatures. Another front in the middle of next week
will bring a chance of rain to the area keeping fire weather
concerns at a minimum.

We already have small fires cropping up in the Olympics and
Cascades even without elevated fire weather conditions. If you
are in the mountains the next few days please be extra careful.
