.SYNOPSIS...
Upper level ridge over Western Washington today weakening
Monday. Upper level trough moving by to the north Monday night
into Tuesday inducing a marine push Monday night. Upper level
ridge well offshore with upper level low off the Northern
California coast giving the area dry northwesterly flow aloft
wednesday through Friday. Upper level trough moving down from
the north approaching the area next weekend.

&&

.SHORT TERM /TODAY THROUGH TUESDAY/...
Satellite imagery shows high clouds over Western Washington this
morning. The cloud cover has prevented any fog from forming.
Temperatures at 2 am/09z were in the 40s.

Upper level ridge over the area today. Southwesterly flow aloft
will keep high clouds moving through Western Washington. Low
level flow offshore. This will push high temperatures into the 60s
and lower 70s.

Upper level ridge remaining in place tonight into Monday with
the ridge weakening Monday. Low level offshore flow weakening
overnight with light low level flow Monday becoming onshore in
the afternoon. With ocean water temperatures between 50 and 52
degrees this switch to onshore winds will cool the coast down
into the mid to upper 50s. Highs over the interior remaining in
the 60s and lower 70s. Lows tonight with the high cloud cover
in the 40s.

Classic marine push scenario Monday night with an upper level
trough moving by to the north inducing an increase in low level
onshore flow. Breezy conditions near the Strait of Juan de Fuca
into Whidbey Island as well as along the coast into the Lower
Chehalis Valley. Increasing clouds Monday night into Tuesday
morning. Onshore gradients weakening Tuesday afternoon with
sunshine returning to the area. Lows in the mid 30s to mid 40s.
Highs Tuesday much cooler, in the lower to mid 50s. Felton

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Extended models showing good run to run consistency through
Friday. Upper level ridge well offshore combining with a
stationary upper level low off Northern California giving
Western Washington dry northwesterly flow aloft. Another round
of frost advisories is possible for the Southwest Interior and
Lower Chehalis Valley in the morning hours both Wednesday and
Thursday. Lows in the 30s and lower 40s. Highs in the mid 50s to
lower 60s.

Model consistency falls apart Saturday with the GFS bringing an
upper level trough down from the north while the ECMWF cuts the
trough off well north of the area. Ensembles not real excited
about the trough scenario but enough solutions with light
precipitation to include a chance of showers Saturday. Lows in
the upper 30s to mid 40s. Highs remaining in the mid 50s to
lower 60s.

.AVIATION...
High pressure aloft remains in place. Northerly surface winds
continue over the area with speeds generally ranging 7-12 kts. This
will persist into this evening before speeds ease below 7 kts. KOLM,
KHQM, and to a lesser extent, KBLI are favored to see some fog and
mist development this morning, lingering until 14-15Z before
clearing out. Otherwise expect VFR conditions with just upper level
cirrus clouds at times.

KSEA...VFR is expected through period under mostly clear skies.
Northerly surface winds hold around 10 to 12 kt through this
evening, easing by around 03Z tonight to 5-7 kts. Any low clouds
that form in the vicinity this morning will remain away from the
terminal area.

.MARINE...
Broad high pressure remains in place across the area through Monday
with a weak thermal trough build up along the west coast, keeping
winds northerly. Winds will increase Monday evening as a front
passes by to the north and stronger high pressure builds in behind
it. Small Craft Advisory conditions look likely across much of the
coastal waters, though will have to continue to monitor the
potential for gales (30-50% probability) through the Strait of Juan
de Fuca with a strong westerly push that moves into Admiralty Inlet
and the Puget Sound. Winds will slowly ease on Tuesday and remain
relatively light through the rest of the week as high pressure
remains in place over the northeast Pacific.

Seas remain 3 to 6 ft through Monday. Seas will then build up to 8
to 11 ft Monday night into Tuesday, and these waves will be steep
with dominant periods of around 8 to 9 seconds. The highest waves
are also likely to be in the northern portions of the outer waters
during this time. Seas look to remain in the 5 to 8 ft range through
the rest of the week.
