Updated aviation discussion and hazards.

.SYNOPSIS...Mainly dry and mild conditions are expected across the
region today, with periods of light rain confined to southwest
Washington and far northwest Oregon. Confidence remains high for a
prolonged stretch of dry weather and above-normal temperatures from
Tuesday through at least Friday as a strong upper-level ridge builds
over the Pacific Northwest. Uncertainty increases toward next
weekend regarding the eventual breakdown of the ridge, though most
guidance suggests precipitation may return by late Saturday.

&&

.DISCUSSION...Now through Sunday... A weak warm frontal boundary
begins to lift northward across southwest Washington and far
northwest Oregon this morning, bringing a period of light rain
mainly north of a Lincoln City to Portland line. Locations south of
this corridor are likely to remain dry, with probabilities of
staying precipitation-free ranging from 80 to 95%. Elsewhere, dry
conditions prevail under mild temperatures, with afternoon highs
generally reaching the mid 50s to lower 60s.

Beginning Tuesday, deterministic and ensemble guidance remains
in strong agreement that upper-level ridging becomes firmly
established over the Pacific Northwest. This pattern will
support an extended period of dry weather, above-normal
temperatures, and generally light winds through at least Friday.
One notable exception will be in the western Columbia River
Gorge and far eastern portions of the Portland and Vancouver
metro area, where increasing easterly pressure gradients will
lead to gusty winds, particularly Wednesday and Thursday.

Ensemble guidance suggests surface pressure gradients between
Troutdale and The Dalles will be around -5 to -7 mb during this
time, possibly peaking up to -8 mb. Under stable low-level
conditions, this setup would favor strong easterly winds through
the Gorge, with potential wind gusts reaching up to 70 mph near
Crown Point, 50 to 55 mph near Corbett, and 35 to 40 mph around
Troutdale. In a possibly stronger but less likely scenario
(peak of -8 mb), wind gusts could be an additional 10 mph
stronger than the aforementioned potential wind gusts. Overall,
these values (-7 and -8 mb) assume the stronger end of the
projected gradient range; weaker gradients would result in
correspondingly lower wind speeds. While some localized tree
damage and isolated power outages are possible, impacts are not
expected to be widespread.

Away from the Gorge, lighter winds and persistent ridging will
promote stagnant conditions, particularly across the central and
southern Willamette Valley. Calm winds and low mixing heights
persisting for several consecutive days may lead to gradual air
quality degradation. Forecast confidence is also lower regarding
sky cover and temperatures in these valley locations, as
inversion-driven low stratus and fog should be slow to clear,
resulting in cooler daytime temperatures compared to surrounding
higher terrain, the Coast Range, and the Cascades. That said,
guidance suggests improved clearing and greater sunshine
potential by late week, even within the central and southern
valley.

Forecast uncertainty increases heading into Saturday and
Sunday. Some model solutions maintain dry conditions under
lingering ridging, while others introduce precipitation as the
ridge begins to weaken. Current probabilities suggest a 20 to
40% chance of rain returning Saturday afternoon, and a 50 to
80% by late Saturday night. Regardless of the timing, rain will
likely continue through Sunday and into the start of next week.

.AVIATION...A frontal system is moving through far NW OR and SW
WA Monday, producing showers near and north of KAST along the coast
and north of the Columbia River for inland areas. Showers should end
by 03-06z Tue. Mainly VFR conditions being observed across the
region with BKN/OVC mid to high level clouds north of a line from
KONP to KCVO. The exception is the far N OR/SW WA coast where
IFR/MVFR ceilings will continue through around 06-10z Tue associated
with the frontal passage. Expecting the mid/high level clouds inland
to become more scattered between 00-06z Tue from south to north.
This clearing will allow for fog/low stratus formation across
portions of the Willamette Valley. Areas south of KCVO, including
KEUG, could see fog formation as early as 06-09z Tue as they will
remain clear through most of the TAF period. For locations north of
KCVO, including KSLE, KUAO, and KHIO, there`s a 40-60% chance of fog
formation sometime between 06-12z Tue. There`s more uncertainty for
Portland area terminals depending on wind direction. Some guidance
suggests winds will remain from the east through the entire TAF
period, which would inhibit fog formation, while other guidance
suggests winds will briefly turn north to northwesterly, which could
allow for better chances of fog formation. Any fog formation should
improve to VFR conditions by 18-21z Tue. Expect light winds mainly
less than 5 kts through the TAF period.

KPDX AND APPROACHES...Predominately VFR conditions through the next
24 hours. Southeast winds around 10 kts calm to below 5 kts after
23z Mon. There`s a 20-30% chance of fog formation between 11-16z
Tue. Uncertainty is due to uncertainty on wind direction. Some
guidance suggests winds will remain from the east through the entire
TAF period, which would inhibit fog formation, while other guidance
suggests winds will briefly turn north to northwesterly, which could
allow for better chances of fog formation. If fog does form, expect
improvement to VFR conditions by 18-20z Tue. -03

.MARINE...A weak front moves northeasterly through the waters
between Cape Shoalwater and Cape Falcon this morning, bringing
increased south winds with gusts 20 to 25 kts. Winds will decrease
below 20 kts again late today and remain 5 to 10 kt through the rest
of the week. Expect wave heights of 10 to 13 feet at 11 to 13
seconds through this evening. Due to a combination of winds and
seas, a Small Craft Advisory is in effect through 1 AM PST on
Tuesday. High pressure builds over the waters Tuesday with southerly
winds less than 10-15 kts and seas less than 10 ft. By Wednesday, an
increasing westerly swell is forecast to push into the waters,
increasing seas to around 10-12 feet around 12-16 seconds through
the end of the week. -12/03

&&

.BEACH HAZARDS...A long period westerly swell will result in a high
threat for sneaker waves persisting through this afternoon. Waves
can run up significantly farther on a beach than normal, including
over rocks and jetties. Sneaker waves can suddenly knock people off
of their feet and quickly pull them into the frigid ocean which may
lead to serious injury or drowning. Caution should be used when in
or near the water, especially those who will be razor clamming this
week. -42
