.SYNOPSIS...Hot temperatures remains the main story through
Monday, with very warm nights offering little relief and breezy
offshore flow continuing into tonight. An Extreme Heat Warning
remains in effect for the Greater Portland/Vancouver Metro and
Columbia River Gorge through late Tuesday, with Heat Advisories
elsewhere inland and along the coast today. Conditions ease
somewhat Tuesday as onshore flow returns, though inland areas
will remain warmer than normal through much of the upcoming
week.

.DISCUSSION...Sunday afternoon through Saturday...This Sunday
afternoon, the forecast remains largely on track as upper-level
ridging continues to strengthen over the eastern Pacific and the
Pacific Northwest, while a surface thermal trough stays
stretched across western Oregon and Washington. Temperatures
have responded accordingly, with rapid warming already underway
inland and along parts of the coast where offshore/downsloping
flow has limited marine influence more than usual.

The hottest stretch of the forecast continues to center on this
afternoon and Monday. Confidence remains high that most
interior lowland locations will climb well into the 90s both
days, with a meaningful chance that a few spots touch or exceed
100 degrees, especially on Monday (20-60% chance of 100+ degrees
on Monday). Even today, localized 100 degree observations
remain possible from Hillsboro south toward Aurora (25-45%
chance of 100+ degrees today). Along the coast, today still
appears to be the peak heating day as offshore flow supports
compressional warming; several coastal communities have a
reasonable chance of reaching the mid 80s, which is notable for
mid-June. Earlier this afternoon, temperatures reached the
upper 80s along the coast due to continued offshore flow, but
has since decreased with the return of onshore flow.

A major contributor to heat impacts will be the lack of
overnight recovery. Tonight is still expected to be the warmest
night of the stretch, with widespread lows west of the Cascade
foothills staying above 60 degrees and many areas having a
decent chance of remaining above 65 degrees (45-65% probability
of remaining above 65 degrees). A few urban and downslope
locations, including parts of the Portland metro, western
Willamette Valley, and central Coast Range, could even struggle
to fall below 70 degrees (60-70% probability of falling below 70
degrees). Monday night into Tuesday morning should be slightly
less extreme, but still quite mild for many inland areas (upper
50s to low 60s inland, mid to upper 50s at the coast).

Taken together, hot afternoons and unusually warm nights will
continue to support widespread Moderate to Major HeatRisk
through at least Monday west of the Cascades. That means heat-
related illness becomes more likely, particularly for those
without effective cooling, sensitive groups, and anyone spending
prolonged time outdoors. Continue to prioritize heat safety:
stay hydrated, limit strenuous afternoon activity, use air-
conditioned spaces when possible, and check on vulnerable
neighbors, family, and pets. Also remember rivers and lakes
remain cold despite the hot weather, increasing the risk of
cold-water shock for anyone seeking relief near the water.

In addition to the heat, breezy offshore winds and very low
afternoon humidity will maintain some fire weather concern
through Monday. The more favored wind-prone areas remain the
central and southern Willamette Valley during the
afternoon/evening and the Columbia Gorge/Cascade gaps overnight
into early Monday morning. While fuels have not yet supported
Red Flag headlines, the pattern of hot, dry, and locally breezy
weather could still allow fires to start and spread in grasses
and other fine fuels. Avoid activities that could produce sparks
or accidental ignitions.

Relief begins to arrive late Monday into Tuesday as a shortwave
moving into British Columbia weakens the ridge and disrupts the
surface thermal trough. This should allow marine influence and
onshore flow to work back inland. Even so, Tuesday does not look
cool, just less hot, with highs still expected to reach the mid
to upper 80s in the Willamette Valley and upper 70s to low 80s
across the southwest Washington lowlands. Heat concerns may
linger Tuesday as well, particularly in more urbanized locations
where warm overnight lows and heat retention remain an issue.

Beyond that, ensemble guidance favors a continuation of
generally warm and dry weather through much of the week.
Wednesday and Thursday look seasonably to above-normal warm
under weaker ridging, with perhaps some shallow morning coastal
stratus returning at times. By late week into next weekend, a
weak trough may try to flatten the pattern somewhat, but no
major cool-down or widespread precipitation signal is evident at
this time. ~12

.AVIATION...High pressure will maintain VFR conditions with clear
skies through the TAF period across all terminals. Surface pressure
gradients tighten this afternoon, supporting breezy northerly to
northeasterly winds across the area, with gusts up to 20-25 kt at
any given terminal. After 01-03z Mon, winds should gradually
weaken as pressure gradients ease, becoming variable around 5 kt
or less inland with light offshore winds along the coast.

In addition, temperatures between 90 to 100 degrees F are forecast
across the Willamette Valley through Monday. Be aware of high
density altitude which may reduce aircraft performance.

KPDX AND APPROACHES...VFR with clear skies through the TAF
period. ENE winds with gusts up to 20-25 kt are expected through
the afternoon. Winds weaken in the evening after 01-03z Mon. /DH

&&

.MARINE...High pressure offshore will maintain the summertime
pattern this weekend and through much of next week. A
strengthening thermal trough along the coast will increase
pressure gradients over the coastal waters again today. As such,
northerly winds will increase to around 15-25 kt with gusts up to
25-30 kt south of Cape Falcon. Winds ease overnight into Monday
morning, but are expected to increase again as diurnally driven
northerlies peak each afternoon and evening through next week.
Seas around 4 to 8 ft at 7-10 seconds are expected to persist,
driven primarily by the northerly wind chop. Seas are expected to
build to around 8 to 10 ft later in the week as a fresh
northwesterly swell builds across the waters. /DH
