aviation discussion updated.

Synopsis A weak ridge of high pressure will move over southwest
washington and northwest oregon tonight with northerly flow aloft. A
few showers or thunderstorms are possible mainly over the cascades
and coast range late this afternoon and evening. Friday, an upper low
will move south down the british columbia coast and over washington
and northwest oregon bringing scattered showers to the area. Cooler
weather will accompany this system with temperatures falling below
normal for the weekend. By Saturday, colder air will bring snow
levels down to the higher cascade passes. No significant
accumulations are expected but those planning recreation for the
holiday weekend will be impacted. Weak ridging late Sunday and Monday
will reduce the shower threat.

Short term Today through Sunday...

weak upper ridge and northeast flow over the area this afternoon with
a few showers popping up over the coast range early this afternoon.

Enough instability for showers and a slight threat of thunderstorms
over cascades this afternoon and evening but conditions over the
valleys are more stable today as a result of all the low level
marine air. Good onshore flow will continue tonight and expect deep
marine layer with lots of clouds after midnight. On Friday a
shortwave is dropping south out of bc and into washington and
northern oregon. This will increase the showers over the area.

Gfs ec NAM show quite a good area of precip... Although light, but nbm
pops are only in the chance category. We may need to up the pops if
the low becomes more active as it develops but climatology for this
time of year is against widespread stratiform precipitation.

On Friday night models have the upper low over eastern oregon with
another shortwave dropping south into the longwave trough. That
brings another significant threat of showers to southwest washington
and NW oregon. By this time cooler air aloft has reached the
cascades and snow levels drop to around 4500 feet. This should bring
some snow showers to the passes, but surfaces will be warm enough to
prevent much accumulation on roadways, unless there is a heavy
shower. Still the cold air and moderate elevation snow will make for
less than ideal camping and recreating conditions for early in the
holiday weekend.

Sunday the main upper low moves south into california and northerly
flow returns, much like yesterday and today. That will allow more
breaks in the clouds and some sunshine in the valleys. The increased
surface heating along the NE flow aloft could result in thunderstorms
again over the mountains. Schneider

Long term Sunday night through Thursday... A broad, strong upper-
level trough finally starts to kick this persistent upper-level
ridge that has been nearly stationary off the west coast off to the
east, meaning a pattern change is in store next week. With the shift
of high pressure inland early next week, we will see partly cloudy
skies and little to no shower activity Tuesday through Thursday. We
will also see temperatures inland get up into the mid-to-upper 70s.

Persisting onshore flow should keep temperatures from getting too
warm next week.

Aviation Expect the inland TAF sites to see MVFR CIGS return
between 12z and 16z. An upper level trough and the associated
remains of an offshore front will move onshore Friday morning and
the associated lift may result in some marginal lifting in the cigs,
but also possibly produce some drizzle or light showers as the
moisture deepens over the region. Interior CIGS should improve to
vfr by Friday afternoon, but coastal sites are likely to remain MVFR
or ifr through the day Friday.

Kpdx and approaches...VFR conditions prevail through this evening.

Expect MVFR stratus to return by 16z Friday. Some drizzle or light
showers may develop in the mid- to late morning. CIGS improve toVFR
by 20z Friday. Bowen

Marine Surface high pressure will remain over the NE pacific
through this weekend. With thermal low pressure over northern
california, winds are northerly over the coastal waters today.

They will be gusting in the 20 to 25 kt range over the outer
waters later this afternoon and this evening. A small craft
advisory is now in effect. A couple of upper level disturbances
will drop south along the washington and oregon coast on Friday
and again on Saturday. Winds will increase over the washington
and far northern oregon waters on Friday in response to this
first system, with gusts likely reaching 30 kt. Isolated gusts to
35 kt aren't out of the question beyond 40 nm, but don't expect
we will need a gale warning at this time. Winds will gradually
subside Sat and should remain fairly benign through the rest of
the weekend. No significant marine impacts are expected over the
first half of next week.

Seas will be a bit of nuisance over the next couple of days.

Current observations show that they remain on the choppy side, at
around 7 to 8 seconds with a dominant period of 9 to 10 seconds.

Decided to issue a small craft advisory for pzz270 starting late
this evening, as model spectral guidance suggests that square
seas will return. In the meantime, strong winds off of vancouver
island will result in seas building Friday into the weekend.

Expect seas to build into the low teens across our coastal waters
fri morning, and remain above 10 ft through at least Sat morning.

Seas are expected to gradually subside sat, reaching 5 ft or less
by sun. Pyle
