Area Forecast Discussion
National Weather Service Seattle WA
240 PM PDT Sat Jun 3 2017

.SYNOPSIS...An upper trough just offshore will weaken and move
ashore on Sunday. The air mass over the region will warm and dry
for the first part of next week. An upper level low pressure
system will affect the region starting on Thursday--with cool
showery weather starting on Thursday and lasting into next weekend.

&&

.SHORT TERM...Mid and high clouds are moving inland this afternoon,
revealing the large areas of broken to overcast lower clouds--but
sunbreaks were increasing, and the immediate coast and coastal waters
were mostly sunny. The upper trough just offshore will weaken further
and move ashore on Sunday and the air mass aloft will cool a little.
Temps should be about the same on Sunday--mostly stuck in the 60s for
highs, onshore flow will likely be a little stronger, but with the
air mass a little more unstable, perhaps there will be more sunshine
on Sunday despite the trough. Upper heights will rise as the air
starts to warm and dry on Monday.

.LONG TERM...Temps will warm through Tuesday and Wednesday and 850mb
temps will probably peak on Wednesday around 17c, so it could even
be a bit warmer than the current forecast. But then another stronger
trough nears the region. Southerly flow aloft will be a good weather
pattern for increasing showers, and cool temps again starting
Thursday.
Shower activity and perhaps a couple of periods of rain are likely
into next weekend as the center of the upper level low pressure
system gradually moves inland over the Pacific Northwest.

&&

.AVIATION...An offshore upper level trough will keep flow aloft from
the southwest today while at the surface high pressure over the
coastal waters will allow for low-level onshore flow. The air mass
remains somewhat moist...at least at the lower levels... and
generally stable.

Clouds over W WA very slow to break up...with most obs still
recording BKN-OVC conditions...however a few breaks in the clouds
can be seen here or there. Fortunately...at least cigs have lifted
as forecast with the entirety of the area currently under VFR
conditions and remaining that way at least until very early Sunday
morning...when some cigs may dip down into high-end MVFR conditions.
 SMR

KSEA...Lingering stratus slowly breaking up this early afternoon
should still result in SCT-BKN conditions by late afternoon.
Variable winds 3-5 kts becoming northwesterly 5-9 kts after 00Z this
afternoon before returning to variable 3-5 kts late tonight.

&&

.MARINE...A ridge of high pressure over the coastal waters
combined with lower pressure east of the Cascades will maintain
light to moderate onshore flow for the next several days.

Winds in the strait have fallen below SCA criteria for now...but
model progs suggest winds will ramp back up into SCA range late this
afternoon...so will leave current headline untouched. Current
forecast also suggests that Northern Inland Waters may need to be
included into current SCA for Sunday night...but as this falls into
the third period...will leave for next shift to include the
zone...should forecasts remain consistent. Have opted to leave
Admiralty Inlet out of the action as looks like bulk of the SCA
speed winds will remain north of there. Previous shift was concerned
about the potential for gales in the strait come Sunday
afternoon...but it seems current model solutions have backed away
from that prospect...thus no additional watch is needed at this time.

The pattern of onshore flow with late afternoon and evening Small
Craft Advisory conditions in the eastern two-thirds of the Strait
will continue through the first half on next week. Albrecht/SMR

&&

.SEW WATCHES/WARNINGS/ADVISORIES...
WA...None.
PZ...Small Craft Advisory until 5 AM PDT Monday for Central U.S.
     Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait
     Of Juan De Fuca.
