.SYNOPSIS...
A warm and dry weekend is taking shape, with temperatures
climbing steadily into early next week. The hottest day is
expected to be Monday, when many spots across the interior
valley could reach the low 90s. After that, temperatures cool a
bit but remain on the warmer side. We are also watching for a
slight chance of thunderstorms over the Oregon Cascades Monday
and Tuesday.
&&
.DISCUSSION...Now through Friday...Temperatures start to climb
today as high pressure strengthens overhead. Skies will clear up
more compared to recent days, especially in the afternoon,
allowing for warmer air to build in. Inland can expect highs in
the upper 70s to low 80s today, with Sunday running much warmer.
By Sunday afternoon, there is a 30-50% chance that the interior
valleys will reach 90 degrees. Cooler air near the surface and
a bit of onshore breeze might keep some spots slightly cooler,
particularly along the coast or in more elevated terrain. The
warming trend continues into Sunday night as offshore flow
strengthens, setting the stage for Mondays heat.
Monday looks to be the peak of the heat, with widespread highs
in the low 90s expected across the inland valleys. Even coastal
area will feel warmer than normal, though still mild compared to
inland spots. This heat may be uncomfortable to some, especially
for those without access to cooling. There is also a 15-30%
chance of isolated thunderstorms over the Oregon Cascades Monday
afternoon and evening, especially from Lane County southward. A
weak system off the California coast is helping to draw
moisture into the mid-levels, which could support storm
development in terrain-favored areas. Ensemble guidance supports
modest instability, particularly in the central Oregon Cascades.
If that moisture tracks farther north, there could be some
activity closer to Mount Hood, but confidence is lower for that
scenario. By Tuesday, thunderstorms chances remain, but activity
looks less widespread and less organized.
After Monday, temperatures dip slightly but stay above average.
Highs for the middle of next week will likely hover in the low
to mid 80s for much of the Willamette Valley, while overnight
lows will stay mild, mainly in the 50s. Ensemble clusters
generally agree on maintaining a warmer-than-normal pattern into
late week, though any significant cooling appears unlikely
through at least Friday. ~Hall

.AVIATION...VFR conditions inland are expected to slowly degrade
towards MVFR through 08Z-10Z Saturday. However, the stratus deck
is expected to be thinner than previous nights, so inland
terminals could see conditions bouncing between low end VFR and
high end MVFR, or a shorter period of prevailing MVFR. At the
same time the VFR to IFR conditions along the coast are expected
to become a mixture of MVFR and IFR conditions. Occasional LIFR
conditions (15-25% probability) could be observed as well along
the coast through 15Z-18Z Saturday. Any lowered flight conditions
are expected to improve to predominantly VFR from 16Z-20Z
Saturday and those conditions are expected to persist through the
remainder of the TAF period.
Winds across the airspace remain light and from the west/northwest
through around 15Z-18Z Saturday. Then, building high pressure
begins shifting winds northerly, with generally offshore flow
taking hold through the rest of the TAF period into Sunday.
PDX AND APPROACHES...Prevailing VFR conditions through 09Z-12Z
Saturday. Then a 40-60% probability of MVFR ceilings developing.
Around 17Z-19Z Saturday conditions are expected to improve VFR.
Light northerly winds persist though around 18Z Saturday, then
offshore flow will slowly develop through the remainder of the TAF
period. /42
&&
.MARINE...Onshore flow persists with little change in the
forecast. Today, conditions will begin to shift as a ridge of
high pressure slowly builds over the Pacific and a low over the
Great Basin shifts north and east. The combination of these two
features will result in robust northerly winds across all waters.
This typical summertime pattern will bring winds to 15-20 kt with
gusts up to 25 kt through all of the waters spreading from south
to north. Northerly winds expected to increase for zones PZZ273,
PZZ2513, PZZ272 and PZZ252 on Sunday with gusts up to 30 kt.
As a result have maintained the current suite of Small Craft
Advisories as well as extended the duration.
On Sunday through Tuesday temperatures will rise considerably and
a thermal trough forms which will maintain northerly winds across
all waters. This will likely result in Small Craft Conditions
persisting through the start of the upcoming week.
Seas will be predominately west-northwest with a northerly wind
waves. At this time, the wind wave will be the dominate feature.
However, conditions will see little change as overall they will
not rise considerably. Looking at seas of 5-6 ft at 9 seconds
today building to 7-9 ft at 9 seconds Sunday and Monday. Seas and
winds are expected to slowly subside by midweek as the ridge
decays. /42
