Synopsis for the southern washington and northern oregon coast.. High pressure over the northeast pacific and thermal low pressure over southwest oregon will maintain our northerly wind pattern for much of the next week. Winds and seas should temporarily ease a bit Sunday through Tuesday as thermal low pressure shifts inland.

area forecast discussion

900 am pdt Sat jul 21 2018

Synopsis An upper trough will result in near seasonal temperatures
today. A thermal trough over the region the next couple of days will
result in much warmer weather Sunday through Wednesday. Slight
cooling is possible Thursday as a weak upper trough moves by, but
the inland temperatures will remain above normal into the weekend.

Short term Today through Tuesday. Water vapor imagery shows an
upper trough moving over the pacific NW today. Low marine clouds are
along the coast from around lincoln city northward into southwest wa.

Visible satellite imagery and surface obs also show a thin line of
low clouds along the columbia river to around the portland and
troutdale area. The clouds inland will burn off rather quickly by
mid-morning while the clouds at the coast will persist through
midday before thinning and clearing this afternoon. High
temperatures this afternoon will be near the seasonal normals (low
to mid 80s inland, mid to upper 60s coast).

The remainder of the previous discussion follows. Upper level
heights build tonight and Sunday in the wake of the departing
trough. A shallower marine layer will keep coastal clouds closer to
the coast tonight. A thermal trough sets up near the cascades Sunday
afternoon. The lack of morning clouds combined with a warmer airmass
will result in a 10+ degree warming in the interior Sunday
afternoon, and expect temperatures in the willamette valley to peak
in the low to mid 90s. If the thermal trough does set up west of the
cascades, light east winds will develop over the cascades, and
possibly advect smoke from wildfires east of the cascades to the
west. Have not put smoke into the forecast yet, but due to
uncertainty on how much smoke output the fires will have Sunday. The
wildfire smoke models do not show any smoke moving west Sunday, but
the hrrr vertically integrated smoke model shows smoke from
wildfires south of the area moving over the cascades of lane county
Sunday morning as the near-surface SE winds develop. The smoke
output of the fires east and south will be monitored today.

Hot weather continues Monday and Tuesday as the thermal trough
lingers near the cascades and high pressure aloft persists. Models
suggest that Monday will be the hottest day of the week with inland
temperatures peaking in the upper 90s. Models tend to under forecast
high temperatures a few degrees in these conditions so have
forecasted temperatures slightly above the model's suggestions. The
temperatures will be slow to cool at night with temperatures
remaining in the low 70s until around midnight. The coast will be
cooler with afternoon temperatures in the upper 60s (near newport) to
mid 70s (near astoria). Tw tj

Long term No changes. Previous discussion follows... Tuesday night
through Friday... Dry weather and above
normal temperatures will remain into next weekend. The GFS and a
majority of its ensemble members depress the ridge slightly as a
shortwave trough moves into the region wed-thu. It is not much of a
trough though, 500 mb heights remain above 585 dam, and warm weather
will continue inland with temperatures peaking in the upper 80s to
low 90s. Coastal areas remain cooler with light onshore flow. Mh tj

Aviation A low level northwesterly flow pattern under building
upper level high pressure later today and tonight will lead to
primarilyVFR conditions areawide through 18z Sunday. The main
exceptions to this will be along the north coast this morning
where MVFR CIGS will hold on through ~18-20z Saturday. There is a
chance ifr CIGS may push more solidly onto much of the coastline
between ~09-18z Sunday, but confidence is low given the pattern
and differences between models.

Kpdx and approaches... A northwesterly low level flow pattern will
lead to primarilyVFR conditions through 18z Sunday. Neuman

Marine High pressure over the northeast pacific and thermal low
pressure over southwestern oregon will result in a fairly typical
summer-time northerly wind pattern for much of the next week. Expect
wind gusts of 25 kt across the central oregon waters through tonight
with winds peaking during the afternoon and evening hours. Do not
think steep and hazardous seas criteria will be met, but it's not
impossible either. Current models suggest wind gusts of 25 kt across
at least portions of the waters on Sunday, but worried this is
overdone
given the pressure gradient pattern. Otherwise, winds and seas should
remain below advisory thresholds early next week. There is a chance
that a stronger northerly wind pattern will return later next week,
but confidence in this scenario is low at this point. Neuman

Pqr watches warnings advisories
Or... None.

Wa... None.

Pz... Small craft advisory for winds until 3 am pdt Sunday for
coastal waters from cascade head or to florence or out 60
nm.
