.SYNOPSIS…Typical summertime weather is expected through the
weekend, due to high pressure and varying degrees of onshore flow.
Inland temperatures will again be a few degrees above normal today,
while the coast remains cooler with persistent low clouds. A weak
disturbance will strengthen onshore flow tonight and Thursday,
bringing cooler temperatures inland. Temperatures will be near normal
Thursday through Saturday, then a warming trend begins Sunday. Hot
weather is looking increasingly likely next week.


.SHORT TERM…Today through Friday…Latest GOES-West fog product
shows the entire Washington and Oregon coastline socked in with fog
and low clouds, in a sign that cooler temperatures are on the way for
the interior. Thermal low pressure will strengthen further over the
Columbia Basin today, resulting in an increase in the onshore flow.
It will take some time for cooler marine air to fully advect across
inland areas, so this afternoon will be another warm one east of the
Coast Range. With warmer morning temperatures today, many inland
areas should reach 90 degrees today despite the increasing onshore
flow. The coast and adjacent coastal valleys will be cooler today due
to the onshore flow, and low clouds may struggle to clear from the
coastline today.

A weak upper disturbance will slowly approach the Pac NW from the
southwest through Thursday, finally moving onshore later Thursday
night. This will result in a deepening of the marine layer, with
progressively more cloudiness inland Thursday morning and Friday
morning. Spotty drizzle will be possible each morning, mainly on the
coast. Morning low clouds should mostly clear back to the coast by
early afternoon each day, with a better chance for clouds to linger
Friday. The increasing marine influence will result in a gradual
cooldown of inland temperatures, with valley highs in the lower to
mid 80s Thursday and around 80 Friday.Weagle

.LONG TERM…Saturday through Tuesday…After another seasonable day
Saturday, forecast models and their ensembles are showing a strong
signal toward hotter temperatures early next week. Overall, the
warming should start Sunday as weak upper troughing gives way to a
strong upper ridge. However the ECMWF and GFS ensemble systems remain
split into two very different camps regarding just how hot it will
be. The NBM incorporates all of these ensembles and then some,
including elements of the Canadian GEM as well. The ECMWF has by far
been more bullish regarding the heat than the GEFS, with ensemble
means consistently in the neighborhood of 100 degrees for the
Willamette Valley next Monday, Tuesday, and Wednesday. Meanwhile, the
vast majority of GEFS members are not nearly as hot, with highs in
the mid 80s to mid 90s. Cluster analyses suggest the ECMWF members
support an upper ridge axis closer to the coast, while the longwave
pattern is shifted further west in most GEFS members, allowing some
shortwave energy to clip the Pac NW from time to time on
northwesterly flow aloft. The GEFS-favored solution is more like what
we have seen thus far this season, with plenty of shortwave energy
reaching us from the Gulf of Alaska.

However it is hard to ignore the excellent agreement between ECMWF
members, with 80 percent of its members showing 850 mb temps in
excess of +20 deg C and an ensemble median and mean around +24 deg C
next Tuesday. This is reason enough to forecast high temperatures
around 100 degrees, if not hotter, for our inland valleys. Largely
driven by EC ensemble members, the NBM probabilistic guidance shows
roughly a 60 percent chance of the Willamette Valley reaching 100
degrees by next Tuesday, with roughly a 35 percent chance of reaching
105 degrees, and 15 percent chance of reaching 110 degrees. Nights
would struggle to cool off in such a heat wave, with NBM showing a 40
percent chance of lows failing to fall below 70 deg F at PDX one or
more nights early next week. Conversely, the NBM only shows a 10
percent chance of the Willamette Valley failing to reach 90 degrees
early next week. In other words, NBM probabilistic guidance suggests
it is more likely for Portland and Salem to reach 110 degrees than it
is for highs to remain in the 80s early next week.

So, while details are still uncertain, confidence is high that it
will be either hot or very hot early next week. People should begin
to think about what actions they need to take to find relief from
extreme heat, in case some of those higher-end temperature forecasts
come to fruition. Weagle


.AVIATION…Low level northwesterly flow under high pressure
aloft will result in predominantly IFR conditions along the coast
and VFR conditions inland through 12z Thursday. Marine stratus
will likely erode back to near the coast for several hours midday
into this afternoon and may even produce a several hour stretch of
VFR conditions. If that does happen, marine clouds appear likely
to quickly congeal and begin spreading back onto the coast and into
the coastal gaps between 23z Wednesday and 12z Thursday. The
marine layer appears likely to deepen overnight as an upper level
low pressure approaches the Pacific Northwest so IFR conditions
along the coast in the evening may trend into MVFR thresholds
towards 12z Thursday. A southwest-to-northeast orientation of the
pressure gradient force should favor marine clouds pushing up the
Umpqua and Siuslaw River Valleys more so than normal. This
appears likely to result in low end MVFR ceilings reaching KEUG
around 12z Thursday or shortly thereafter.

KPDX AND APPROACHES…Low level northwesterly flow under high
pressure aloft will result in predominantly VFR conditions through
12z Thursday. Marine stratus is slowly moving up the Columbia
River this morning and near KKLS at the moment. This certainly
suggests there is a small chance that IFR ceilings could briefly
reach KPDX between 14-16z Wednesday, but it still appears those
odds are 20% or less. /Neuman


.MARINE…Surface high pressure will remain over the northeast
Pacific for the next week. Thermally induced lower pressure has
weakened and shifted well inland. This will result in decreasing
winds across the waters over the next 12-24 hours. A passing upper
level low pressure will briefly help to turn winds weakly
westerly or southwesterly Thursday.

Thermally induced low pressure will become re-established over
northern California over the weekend and result in increasingly
gusty northerly winds across the waters. Thermally induced low
pressure appears increasingly likely to shift northward into
western Oregon and western Washington early next week. This
should result in winds decreasing across the waters, but this will
still be a favorable pattern for the Vancouver Island jet to keep
seas relatively steep and choppy as a NW fresh swell moves across
the waters.

Speaking of seas, expect significant wave heights to generally
remain in the 4-6 ft range for much of the next week. While a long
period SW swell will move across the waters over the next several
days, the bulk of the significant wave heights will be comprised
of a fresh swell. Wind waves will become more significant over the
weekend as northerly winds increase across the waters. /Neuman
