Area Forecast Discussion
National Weather Service Portland OR
911 PM PDT Wed Sep 15 2021

.SYNOPSIS...Chilly and mostly clear tonight, followed by sunny and
seasonable weather Thursday. Increasing clouds Thursday night as a
potent Pacific frontal system approaches the Pac NW coast. This
front will usher in cool, wet, and blustery weather to the entire
forecast area by Friday night, followed by cool, showery conditions
through the weekend. Rain will be locally heavy, especially in
orographically favored portions of the Coast Range and Cascades,
where over three inches of rain is possible.

&&

.SHORT TERM...Tonight...Water vapor satellite imagery this evening
reveals a shortwave trough sliding east-southeastward across southern
British Columbia and northern Washington. This is resulting in some
cirrus moving across our northern zones with otherwise clear skies
across the CWA. With dewpoints generally in the mid 30s to low 40s,
temperatures should cool off relatively quickly later tonight when
winds die down. This should allow a lot of the typically colder
valley locations like Hillsboro, Battle Ground, etc. to drop down
into the mid to upper 30s later tonight with perhaps some patchy
frost in spots. Do not think enough of a zone will receive frost to
warrant a frost advisory, though. Adjusted temperatures in a few
specific locations where weather stations in the past have realized
these colder temperatures under similar nights. Otherwise, the rest
of the forecast is on track and no changes were made to the forecast.
/Neuman

Previous discussion from Wednesday afternoon for Thursday through
Friday night follows...After a cool start, temps should climb quickly
Thursday under abundant sunshine, a warming air mass, and drier
low-level northerly flow. Thursday afternoon high temps should end up
in the upper 60s to mid 70s for the lowlands.

By Thursday night, there will be a sense of the upcoming pattern
change as clouds increase and winds turn more southerly. A warm
front aloft will push eastward across the forecast area while the
trailing cold front approaches the northern coast Friday. Models
continue to keep the strongest forcing and moisture transport north
of our area on Friday, mainly toward the Olympic Peninsula and
Vancouver Island. Expect occasional rain and drizzle north and west
of Portland during the daytime hours. Meanwhile, areas south and east

of Portland will likely remain dry. This will likely allow
temperatures to warm back into the mid to upper 70s, and possibly up
to 80 near Eugene with dry conditions. Breezy southerly winds will
increase Friday, especially along the coast where gusts to 50 mph
will be possible by Friday evening, while gusts up to 35 mph are not
out of the question for the Willamette Valley.

A potent cold front will then gradually slide to the southeast
across the forecast area Friday night. This will bring significant
rainfall amounts to the entire area by Saturday morning. A strong
120 kt upper level jet associated with this system will drive the
deep moisture transport over the area. GEFS and ECMWF ensembles
continue to strongly suggest at least a moderate atmospheric river
involved with the front. Will likely see steady rainfall during a 6
to 12-hour period, heavy at times, as the front moves through late
Friday night into Saturday morning. Many locations may see 0.5 inch
to 1.0 inch of rainfall occur during this time period, with greater
amounts likely along the coast and at higher terrain. /DDH

&&

.LONG TERM...Saturday through Wednesday...Deep upper level trough
will remain offshore Saturday while post frontal showers develop by
Sat afternoon. There may be a lull in precip at times during the
day. Southerly winds will remain breezy, but not expected to be as
strong as Friday. The upper level trough will move across the
Pacific NW Sunday as several models bring another potent shortwave
as a focus for precipitation late Sat night and Sunday. By Sunday
afternoon and evening, northwest flow aloft is currently expected
while a weak surface low is forecast off the Washington coast. This
set up in particular could indicate a chance for a few thunderstorms
to develop on Sunday across much of the area.

Total rainfall amounts for the weekend event continues to range
around 1-2 inches for the inland valleys by Monday morning, and 2-4
inches for the higher terrain. The latest NBM continues to increase
the chance of 1 inch of rain over the weekend to 93% for Portland,
with a 55% chance of 2 inches. The cool air mass behind the front
will also lower snow levels, potentially giving Timberline Lodge
(6000 ft elevation) their first dusting of the season.

Showers are expected to taper off Monday as the upper trough exits
east toward the Rockies. Should remain drier Tuesday as well with
some light offshore flow allowing temperatures to warm back to
seasonable normals. Models are not in very good agreement by the
middle of the week. /DDH

&&

.AVIATION...04z update: Not much change. Breezy conditions in the
Willamette Valley will continue to ease overnight. Previous
discussion follows:

Stable west to northwest flow aloft will maintain dry weather
through early Thu. Mostly clear skies tonight, with variable
cirrus clouds. Though stays mostly clear tonight, will see patchy
fog in valleys. Also, will have pockets of lower MVFR or high
end IFR along the S WA and N OR coasts, impacting KAST and
perhaps as far south as KTMK.

For detailed regional Pac NW aviation weather information, go
online to: https://weather.gov/zse

KPDX AND APPROACHES...Dry, with stable west to northwest flow
aloft. Breezy northwest winds have begun to ease and will
continue to do so through 06Z. Not much change overnight into
Thu am, with mostly clear skies. Northerly winds will pick again
to around 10 kts Thu afternoon. -Rockey/CB

&&

.MARINE...High pres offshore will maintain modest north to south
pres gradients. This will maintain gusty winds of 20 to 25 kt on
the central coastal waters overnight, though strongest winds
will be to south of Newport. The Small Craft Advisory has been
allowed to expire for the northern zones but continues through 5
AM for the central zones. Seas stay in the 4 to 7 ft range,
though with gusty winds, expect locally choppy seas to 7 or 8 ft.

A strong cold front will push across the coastal waters later
Friday into Friday night. Winds will become southerly, and pick
up. Latest models and ensembles showing a decent chance for gale
force winds on Friday. Have extended Gale watch to include all
waters for Fri afternoon into Fri night. Will see how models
refine timing and strength over the next few runs then consider a
Gale Warning or Small Craft Advisory. Seas also rise a tad to
10 to 12 ft, primarily consisting of steep wind driven waves.
