Synopsis High pressure over the pacific northwest will continue
the very hot temperatures across much of northwestern oregon and
southwestern washington Sunday. A southerly marine surge will be
working up the coast overnight. The marine push will extend inland
late Sunday bringing much cooler temps on Monday. There is a slight
chance for some high-based thunderstorms over the northern portions
of the CWA Monday. Dry northwesterly flow sets up next week across
the region, bringing more seasonable temperatures and a pattern of
morning clouds and afternoon sunshine.

Short term Tonight through Tuesday... A very strong upper level
ridge brought scorching heat to much of the cwa, breaking daily high
temp records for several locations. The airmass over the region is
very warm, with the 00z ksle sounding coming in with around 23 c at
850 mb. Offshore flow aided in the warm temps by helping to mix the
airmass. The thermal trough set up right along the coast earlier
today, allowing the east winds and high temps to reach all the way to
the coast.

Relief is on the way for portions of the CWA tonight. The thermal
trough has shifted and is now draped from the lane county cascades
and foothills up through the north oregon coast range. Offshore flow
will continue overnight into Sun morning for areas east of the trough
axis. For areas west of the trough, increasing onshore flow will
bring welcomed relief from cool marine air. A southerly surge will be
working its way up the coast overnight. Areas from around konp
southward are now showing southerly winds, and these winds will
gradually spread northward through the night. Satellite fog product
shows stratus nearing the central oregon coast in the last hr, and
think it will begin to spread onshore during the 06z-12z time period.

We are also starting to see signs of marine influence in the southern
willamette valley, where keug and kcvo have seen temps cool
considerably over the past couple of hrs and dewpoints are steadily
rising. Have dropped the coast range and southern willamette valley
out of the heat advisory for tomorrow, as this marine influence
should keeps temps quite a bit cooler than we saw today. The fcst
models suggest that offshore flow continues over the northern valley
into Sun morning, with the thermal trough moving over the region in
the afternoon. So expect areas from roughly ksle northward to see
temps near or even just above what we saw today. So will retain the
current heat advisory and excessive heat warning products for the
northern half of the CWA and the cascade foothills. The thermal low
pressure will shift east of the cascades Sunday night and result in
the entire forecast area cooling considerably by Monday.

As the upper ridge bringing the heat shifts east, a weak upper level
impulse lifting northeastward into northern california and oregon
Sunday night and Monday will help to destabilize the atmosphere is it
brushes our southern cwa. At this point, it appears there is a chance
of thunderstorms grazing primarily the lane and linn county cascades
as well as the central oregon coast and even the south half of the
interior lowlands. These will be elevated thunderstorms, so we'll
need watch for changes to the instability moisture to expand or cut
back on the thunderstorm coverage. Pyle mh

Long term Tuesday night through Saturday... Low level onshore flow
will continue through much of the long term period. Models continue
to show a broad upper level trough moving across the forecast area
late Tuesday Wednesday which will bring an increase in cloud cover
along, with some patchy morning fog or drizzle on the north coast.

Expect much more seasonal temps on Wednesday afternoon. Upper level
ridging will start to build over the pac NW late next week which
will bring slightly warmer temps. The good news is that the ridge
will not be as strong next week which will prevent temps from
becoming outrageously hot. 64

Aviation High pressure and offshore flow will bring
predominantlyVFR conditions to most TAF sites through 06z
Monday. The main exception to this will be along the coast
where a southerly wind reversal will bring ifr conditions to konp
starting sometime between 12z-15z Sunday before transitioning to
MVFR conditions later on Sunday. Ifr conditions will move north
up the coast during the day Sunday and if they get to kast, it
would be around 00z-03z Monday.

Kpdx and approaches... High pressure and offshore flow will bring
vfr conditions through 06z Monday. Bowen neuman

Marine High pressure over the northeast pacific will continue
well into next week. In the immediate short term, a weak low
pressure will move northward across the waters over the next 36
hours. This will result in north to northeast winds across the
outer waters this evening before southerly winds spread northward
across all the waters tonight and Sunday.

A summer-like northerly wind pattern then looks to return late
Monday or Tuesday and continue through much of next week. This
should result in northerly winds peaking generally each afternoon
and evening across the waters, with the strongest winds
generally occurring across the waters off the central oregon
coast. Bowen neuman
