.SYNOPSIS...One more day of benign onshore flow today, with
temperatures running close to seasonal norms. Building high
pressure yields a stretch of hotter weather with temps peaking
in the low 90s during the first half of the coming week. The
pattern will remain conducive to possible thunderstorm activity
along the Cascades each day through Friday.

&&

.DISCUSSION...The region remains under the influence of weak
upper level troughing extending from British Columbia to the
offshore waters of Washington and Oregon this morning,
maintaining onshore flow across the Pacific Northwest. Satellite
imagery shows stratus mostly confined to the outer waters,
leaving mainly clear skies in place over most of the area. As
such, should see a sunnier start to the day in most locations,
which will aid in highs rebounding a few degrees into the low
80s in the interior valleys this afternoon. Temperatures will
continue an upward trajectory on Monday as high pressure begins
to build over the western CONUS, resulting in highs in the mid
to upper 80s in most interior locations Monday afternoon.
Temperatures will peak in the upper 80s to low 90s Tuesday and
Wednesday as the ridge continues to amplify. Still do not
anticipate any widespread heat concerns as guidance remains
rather tightly clustered showing highs topping out in the low
90s, with only a 15-25% chance to reach 95 degrees in most
locations. Temperatures still look to moderate back into the low
to mid 80s during the latter half of the week as the ridge axis
gradually shifts eastward with time.

Forecast thinking has changed little with regards to thunderstorm
potential during the coming week. The amplification of the
upper level pattern will feature unseasonably deep low pressure
over the NE Pacific, leading to a prolonged period of southerly
flow advecting rich mid level moisture into the region. This
will yield a 15-25% chance of showers and thunderstorms along
the Cascades each afternoon and evening from Monday through
Friday. Will continue to keep an eye on Wednesday into Thursday
for a bit better thunderstorm coverage as an embedded
disturbance lifts northward from California and enhances forcing
for ascent. Those with fire weather interests will want to pay
close attention to the forecast in the coming week given the
combination of hot and dry weather with the increased potential
for lightning strikes along the Cascades each day. /CB

.AVIATION...As of 0930Z, widespread VFR conditions are being
observed and reported. However, could see some marine stratus
redeveloping along the coast, but models are not doing well at
least when compared to current conditions. So, this TAF package is
likely to be challenging. With that in mind, am thinking that
some MVFR to LIFR conditions will develop along the coast around
12Z-14Z Sunday and said marine stratus will likely push into the
northern and southern Willamette Valley around 14Z-16Z Sunday.

Coastal locations have a 20-40% probability of lowered flight
conditions developing with KONP having IFR/LIFR conditions with
MVFR/IFR conditions elsewhere along the coast. For inland
locations a 15-25% probability of MVFR conditions developing
around KPDX, KMMV, KUAO, KHIO and KEUG. Overall, confidence is
rather low at this time. Any lowered flight conditions that
develop should improve to VFR starting around 16Z-18Z Sunday and
those VFR conditions are expected to persist through the remainder
of the TAF period. Light winds of less than 5 kt will increase and
become west/northwest at 5-10 kt around 20Z-22Z Sunday.

PDX AND APPROACHES...Generally VFR conditions through around 14Z
Sunday. Marine stratus via the Columbia River could bring MVFR
conditions starting around 15Z Sun. Model guidance is not doing
well resolving this potential marine push, so confidence is low
(10-20% probability) at this time. VFR conditions are nonetheless
favored to return around 16Z-18Z Sunday. Northwest flow continues
at 5 kt or less, increasing to 5-10 kt after 20Z Sunday. /42

&&

.MARINE...Minimal change in the overall pattern through this week.
This is a result of a broad, surface high pressure remaining
anchored across the coastal waters. This is bringing rather
benign conditions, with north/northwest winds through at least
the latter part of the this week. Although there may be a bit of
a easterly component to the flow on Sunday. Tuesday and Wednesday
northerly winds will increase with gusts up to 20 kt range during
the afternoons and evenings. Seas 2 to 5 ft with a dominant period
of 8 to 10 seconds. /42
