Area Forecast Discussion
National Weather Service Portland OR
235 PM PDT Wed Aug 17 2016

.SYNOPSIS...Sunny skies and warm weather today across the area. Will
see some clouds return to the Coast tonight similar to last night.
Weather will change dramatically beginning Thursday and continuing
through at least Saturday as a heat wave develops, with offshore east
winds developing Thursday night and Friday for a significant hot
period across Southwest Washington and Northwest Oregon. Onshore flow
returns Sunday and temperatures will gradually cool down closer to
seasonal normals early next week.

&&

.SHORT TERM...(Today through Saturday)...Clear, sunny skies across
most of our area this afternoon, with a few clouds lingering around
Astoria northward. Will see clouds return to the Coast tonight,
mainly hugging the Coastline and not making it very far inland.

Big change on Thursday as an upper ridge starts to build over the
area, making it hot, hot, hot! Temperatures at the Coast will reach
the mid 70s to low 80s Thursday after some brief morning low clouds,
while the valleys temps will approach 100. High pressure building
over the Columbia Basin Thursday evening will generate easterly winds
Thursday night through Friday. This will make for a sunny and breezy
day on Friday, as well as a hot day along the Coast. With easterly
winds forcing marine air offshore, temperatures in many locations
along the Coast will get up into the mid 80s to even mid 90s. Inland
temperatures on Friday will again get up to around 100 degrees, but
perhaps a degree or two less near the Gorge and on the east side of
the Portland Metro due to breezy easterly winds coming through the
Gorge. As winds ease Friday night into Saturday, the heat will
continue with inland temperatures again getting up around 100
degrees. Increasing onshore flow and clouds developing along the
Coast Saturday afternoon will keep the Coast back down in the 70s to
low 80s. Relief is in sight, right now it appears the heat will start
to dial back down towards normal on Sunday into early next week.

This afternoon we have issued an Excessive Heat Warning for inland
zones below 3000 ft, starting Thursday afternoon and going through
Saturday evening. We have also issued a Heat Advisory for the Central
Columbia Gorge and Hood River Valley Zones for Thursday afternoon
through Saturday evening. Lastly, we issued a Heat Advisory for the
South Washington and North and Central Oregon Coasts just for Friday.
-McCoy

.LONG TERM...(Saturday night through Wednesday). High pressure
remains in place across the eastern Pacific through the first half
of next week. An upper level trough slide south out of the Gulf of
Alaska into the region on Sunday, which will enhance onshore flow
and heights will fall as the air mass cools a little. This will
bring a welcome relief from the near-record heat of this week,
though maximum temperatures Sunday will remain well above normal
across the interior. The upper trough advances and will be over the
area Monday and Tuesday, bringing a return of seasonally typical
temperatures, but the forecast remains dry through the middle of
next week.   Cullen
&&

.AVIATION...A typical summer-time north-northwesterly wind pattern
will allow lifr and ifr conditions to expand into the coastal taf
sites late this afternoon and evening where they will likely
linger through ~18z Thursday. Farther inland, expect predominantly
vfr conditions through 00z Friday as high pressure anchors itself
over the region.

KPDX AND APPROACHES...Building high pressure over the Pacific
Northwest should bring vfr conditions through 00z Friday. There is
a 20 percent chance of a brief high end ifr to low end mvfr cigs
developing over the terminal between 15-17z Thursday, but the
chances appear low enough that will leave it out of the taf for
now. /Neuman

&&

.MARINE...High pressure over the northeast Pacific will bring
breezy northerly winds of 15 to 25 kts to the waters through
Thursday. The strongest winds will likely continue to be across
the far outer waters and off the central Oregon coast during this
period.

An area of gale force winds that will periodically surface off
Vancouver Island in combination with the breezy winds locally
will produce a wind wave/fresh swell that will likely meet
hazardous seas criteria of 7 to 10 ft with dominant periods near 9
seconds through at least tonight. While these conditions may not
be continuously observed at Buoy 29 and Buoy 50 over the next
12-18 hours, farther offshore beyond ~30 nm, steep and hazardous
seas should be much more prevalent. Winds turning more northerly
upstream off Vancouver Island Thursday may prevent the need to
extend the small craft advisory for hazardous into Thursday
afternoon or Thursday night. Nonetheless, models hint at winds
locally spiking Thursday evening over the waters, which may once
again push seas into the steep and hazardous criteria. It should
be noted that a couple models even hint at low end northerly gale
gusts over the waters during this time, but think this is too high
given the pattern so kept the forecast more in the 20-25 kt range.
Nonetheless, this will need to be monitored over the next 24
hours.

The large scale weather pattern will shift Thursday night and
Friday and likely result in breezy northeasterly winds with
localized gusts to 25 kt across the waters on Friday...particularly
near the gaps in the coast range. The northeast winds should be
short lived though as winds turn more northerly Friday night, but
remain gusty to 20 to 25 kt. A weak southerly wind reversal may
work its way northward up the immediate coastline over the
weekend, but confidence remains low that it will materialize. And
again, even if winds do turn more southerly, the southerly winds
should remain very weak and short lived. Also, wave periods will
remain short enough over the weekend that it will still be
relatively choppy across the waters even though seas will likely
fall into the mid single digits.

It appears high pressure is likely to redevelop over the northeast
Pacific early next week and bring a return to a typical summertime
gusty northerly wind pattern. /Neuman

&&

.FIRE WEATHER...SEASONABLE WEATHER CONTINUES TODAY...BUT MAJOR
CHANGES WILL START TO DEVELOP TONIGHT AS A STRONG...HOT UPPER LEVEL
RIDGE BUILDS INTO THE PACIFIC NORTHWEST TONIGHT AND THURSDAY. THE
FIRST IMPACTS WILL LIKELY BE POOR TO MODERATE HUMIDITY RECOVERIES
FOR HIGH ELEVATIONS TONIGHT AS THE MARINE LAYER BECOMES COMPRESSED
BY A STRENGTHENING SUBSIDENCE INVERSION. BY THURSDAY AFTERNOON...
THERMAL LOW PRESSURE WILL BE ALIGNED OVER WESTERN OREGON...RESULTING
IN GUSTY NORTHERLY FLOW ESPECIALLY FOR CENTRAL AND SOUTHERN PORTIONS
OF THE WILLAMETTE VALLEY.

THE THERMAL TROUGH WILL CONTINUE TO MIGRATE OFFSHORE THURSDAY
NIGHT AND FRIDAY FOR HOT AND DRY WEATHER ALL THE WAY TO THE COAST
BY FRIDAY. AS HIGH PRESSURE STRENGTHENS EAST OF THE CASCADES...
NORTHEAST TO EAST WINDS WILL BECOME STRONGER FRIDAY MORNING...WITH
GUSTS 30 TO 40 MPH POSSIBLE NEAR THE COLUMBIA GORGE...PORTLAND
METRO AREA...COAST AND COAST RANGE. THE COMBINATION OF HOT AND DRY
CONDITIONS...GUSTY OFFSHORE WINDS AND RECEPTIVE FUELS...HAVE
PROMPTED US TO ISSUE RED FLAG WARNINGS FOR ALL OF NORTHWEST OREGON
AND SOUTHWEST WASHINGTON FOR VARIOUS TIMES BETWEEN THURSDAY AND
SATURDAY. TEMPERATURES WILL APPROACH 100 DEGREES THURSDAY AND
FRIDAY FOR INLAND VALLEYS...LIKELY SATURDAY AS WELL. THE DRY
OFFSHORE FLOW WILL CAUSE HUMIDITY TO DROP INTO THE TEENS FOR MUCH
OF THE DISTRICT...WITH POOR OVERNIGHT RECOVERIES FOR ALL BUT THE
IMMEDIATE COAST AND SHELTERED VALLEY BOTTOMS. WINDS SHOULD EASE
FRIDAY NIGHT AND SATURDAY BUT THE PRESENCE OF THE THERMAL TROUGH
WILL KEEP IT HOT...DRY...AND UNSTABLE INLAND SATURDAY. COOLING
WILL BEGIN ALONG THE COAST SATURDAY...THEN SPREAD INLAND SATURDAY
NIGHT AND SUNDAY AS THE THERMAL TROUGH MOVES EAST OF THE CASCADES
AND ONSHORE FLOW RETURNS.  WEAGLE

&&

.CLIMATE...Record breaking temperatures are possible Thursday through
Saturday as the region will experience excessive heat. The forecast
confidence is higher for the inland locations than the coast,
especially on Saturday where the timing and location of coastal
clouds can make a 20 to 30 degree difference in the coastal
temperatures.

In the table below, 'FCST' means the current Forecast, 'T' is the
High Temperature, and 'REC' means daily record high temperature. The
year listed is the year the record was last set or tied. TJ
