Synopsis An upper ridge that spread into the pacific northwest
Monday will slowly move east tonight and Wednesday as a system slowly
approaches the b.C and pacific northwest coast. The marine layer will
extend farther inland Wednesday, resulting in some cooling. There is
a slight chance of a shower in the oregon cascades tonight and early
Wednesday. A weak front will move through the pacific northwest
Wednesday night and Thursday, bringing significant cooling and a few
showers. Friday will see drying and warming for a typical summer day,
then look for significant warming this weekend into early next week.

Short term Tonight through Friday... Satellite imagery this evening
shows marine stratus well entrenched along the coast with a couple of
sites reporting lowered visibility and even some light rain. With
that in mind, added patchy light drizzle and patchy fog to the
forecast for the coast through tonight. Also adjusted cloud cover to
reflect current trends as well as a marine push further inland
tonight. Will also see more of a southwest push that will bring
clouds into the southern willamette valley. Radar trends show shower
and thunderstorm activity beginning to shift a little bit north and
west, as expected, so kept some slight chance pops along the cascade
crest for later tonight. Bowen
the remainder of the short term forecast discussion is unchanged...

Wednesday will see greater coverage of low clouds inland in the
morning when compared to today, coming inland along the columbia
river as well as the southern coastal gap towards and past eugene.

Even though it will burn off inland in the afternoon, this will cool
temps back down closer to seasonal normals on Wednesday. Increasing
southwest flow aloft will ensure that any convection will be east of
our cascades in the afternoon.

Wednesday night and Thursday will see the approaching offshore system
move through the pacific northwest. This will bring cloudy conditions
to the area with a few showers, as well as cooling of afternoon
temps. Thursday should see 60s at the coast and 70s inland.

Westerly flow spreads in Thursday night and Friday, with morning
clouds especially north Friday giving way to sunshine in the
afternoon. Temps will be closer to seasonal normals as Friday is a
very typical summer day. Tolleson

Long term No changes. Previous discussion follows... Friday night
through Tuesday... Shortwave ridging will build over the pacific
northwest and bring warming temperatures through the weekend. Several
days of 90f+ temperatures appear increasingly likely for the
willamette valley with Sunday and Monday appearing the hottest. While
some models suggest even hotter temperatures are possible on these
days, most generally keep temperatures closer to reasonable levels so
the forecast was trended towards this idea being the most likely to
occur.

This upcoming hot stretch will likely produce a multi-day period of
critical fire weather conditions as well. East to northeasterly winds
should allow smoke to filter back into the region Sunday and Monday.

The flow may turn a little more southerly aloft as the ridge begins
to break down late in the weekend or more likely early next week so
will need to monitor for the possibility of thunderstorms even though
models at this time do not really show it despite the synoptic
pattern appearing somewhat favorable. Neuman tolleson

Aviation Ifr or lower fog and stratus has returned to the
coast and will persist overnight through at least 18z wed.

Across the interior, expect continued smoke to occasional form
vfr CIGS this evening through early tonight. Onshore marine push
will bring lower MVFR CIGS into much of the willamette valley
between 12-14z through around 18z when lifting and scattering
will bring a return ofVFR conditions.

Kpdx and approaches...VFR through late tonight with occasional
cigs due to smoke. A period of MVFR stratus around 2000 ft will
arrive by 12z and will continue through 18z, with a return toVFR
conditions thereafter. cullen

Marine Conditions remain relatively benign across the coastal
waters, with winds less than 15 kt and seas around 5 ft. A weak
front crosses the waters on Wednesday, but the primary impact
will be a slight shift to west winds, with speeds remaining below
advisory thresholds. High pressure builds across the waters
starting late Wednesday night, and thermal low pressure
strengthens again later in the week. This will bring a return of
advisory strength winds to the southern zones by Friday and
across the northern coastal waters over the weekend. Seas will
generally remain 4 to 6 feet through the week, but may build to 7
feet and become rather steep at times this weekend when the
stronger winds develop. Cullen
