Synopsis for the southern washington and northern oregon coast.. High pressure over the northeast pacific and thermally induced low pressure over northern california and the great basin will persist for much of the week resulting in relatively minor fluctuations in winds and seas from one day to the next.

Synopsis Hot temperatures with smoke and haze will give way to
much cooler temperatures and occasional drizzle and rain this
weekend.

Short term Today through Friday... Smoke will continue be a factor
as n-ne flow persists aloft due to an upper trough over southern and
eastern oregon. As models previously suggested, have seen at least a
slight thinning in the smoke due to the fact that there's less smoke
to tap into across northeastern oregon and southeastern washington.

The thinner smoke has allowed additional warming today, with
temperatures reaching 90 degrees nearly across the board. The
immediate coast is the exception, but observations even there show
temperatures in the 80s.

Models have been fairly consistent in showing a SW push of marine air
pushing through the gaps in the coast range and reaching eugene and
corvallis Wednesday. This may hold their temps in the 80s Wednesday
afternoon, while areas north and east remain hotter with another day
of highs in the 90s for the valleys. Of course, temperatures will
highly depend on how much smoke remains in the air Wednesday. Either
way, the marine layer will likely redevelop along the coast tonight
and Wednesday morning, returning the coast to more typical cool
maritime weather.

The more substantial push of marine air arrives Wednesday night into
Thursday morning as the upper level ridge breaks down and a zonal
north pacific jet breaks through, pushing an upper trough toward the
coast. This may wring some drizzle out of a deepening marine layer
along the coast and coast range Thu morning, especially north. Spotty
drizzle will even be possible inland Thursday morning, as marine
clouds push well inland. Thursday afternoon will be much cooler due
to the cloud cover and strong onshore flow, with highs in the mid 70s
to lower 80s for the inland valleys. Cooled temperatures a little bit
Thursday, in line with latest model trends. Cooler temperatures,
morning clouds, and some possible drizzle carry their way into Friday
with the biggest difference being even cooler temperatures than
Thursday. Went with model trend of slightly cooler than the previous
forecast for Friday as well. Bowen

Long term Friday night through Tuesday... Models continue to be
firm on cooler weather continuing through early next week. As the
mean upper ridge position retrogrades west toward the north-central
pacific, this opens the door for persistent upper troughing over the
pac nw, a significant change from the near constant heat. With the
madden-julian oscillation in the active phase for the west pacific
and remnants of typhoons cimaron and soulik expected to recurve, this
appears to be the type of pattern shift that could actually bring
rain to the pac nw. Models oblige and push a decent cold front
through the pacific NW late this weekend. This system appears to
entrain at least some moisture from one of these recurving typhoon
remnants, so there appears to be a decent shot for at least the
higher terrain to get measurable rain Sunday night into Monday. Upped
pops, particularly for the cascades and coast range, but kept them in
the chance category, as models are notorious for their handling of
entrainment of tropical remnants. Could see a return to some ridging
Tuesday, so upped temperatures a little bit, but only to around
seasonal averages. Bowen

Aviation East to northeasterly winds tonight will allow smoke
to persist across most of the area through 00z Thursday. This
will generally result in MVFR and low endVFR visibilities
across northwest oregon and southwest washington. There could be
some temporary deteriorations into high end ifr visibilities at
times, but these will be difficult to predict. Increasing
westerly winds on Wednesday should begin to clear out the low
level smoke, but it will likely be a slow process. A southerly
marine surge should result in lifr ifr conditions spreading
northward up the coast between 12z Wednesday and 00z Thursday.

Kpdx and approaches... Smoke should continue to produce predominantly
low endVFR and occasional MVFR visibilities through 06z Thursday.

Increasing low level westerly flow after 00z Thursday should begin
to clean out the smoke, but it may be a slow process. Neuman

Marine Surface high pressure will linger across the northeast
pacific for much of the next week. Meanwhile, a thermally induced
surface low pressure will remain over northern california and or
the great basin. This will result in persistent northerly winds
generally remaining under 20 kt for much of the upcoming week. It
should be noted that seas will be a little more choppy than usual
over the next couple of days as two different wave trains move
across the waters. Neuman
