Area Forecast Discussion...UPDATED
National Weather Service Portland OR
829 PM PST Thu Dec 9 2021

Updated Aviation and Marine Sections

.SYNOPSIS...Shower activity continues, with mostly light rain in the
lowlands and snow in the Cascades. After a relative lull on Friday,
a strong front will move through the region on Saturday accompanied
by strong southerly winds, rain, and heavy snow in the Cascades.
Cool and wet weather continues into next week.

&&

.SHORT TERM...TONIGHT THROUGH SUNDAY...RADAR imagery shows
widespread showers ongoing this afternoon as an upper level
shortwave trough is exiting east of the Cascades. With the colder
air aloft today, noted by 850 mb temperatures around -4 to -5 C,
have received reports of snow down to 700 ft today, mainly within
the more intense showers. Snow accumulation has generally remained
above 1500 ft, with reports of 6 to 8 inches in the past 12 hours in
the higher terrain of the Cascades. Expect showers to continue this
evening through tonight as a dirty ridge remains offshore. Westerly
850 mb flow and orographic effects will keep the western slopes of
the Cascades in a favorable pattern for snow showers to continue.
Ended up extending the Winter Weather Advisory through Friday
morning for the north Oregon and south Washington Cascades for an
additional amount of 4 to 8 inches expected. There also remains a
slight chance for thunder along the coast this evening, but
lightning detectors have not indicated any strikes yet today.

Shower activity should become more subdued on Friday as weak
shortwave ridging crosses the region and snow levels climb to around
3000 feet. Moist onshore flow however will maintain at least some
light precipitation chances, especially over the higher terrain. By
Friday afternoon, a warm front pushes across the northern coast
bringing more steady rain to far northwest OR and southwest WA.
Amounts expected to remain light through Friday evening.

More impactful weather will arrive late Friday night and continue
through Saturday as a strong front approaches the region. A fairly
quick moving atmospheric river will slide south along the BC coast
Friday night and drop across the Pacific NW on Saturday. GEFS and
ECMWF ensembles IVT values over 250 kg/ms are forecast, peaking just
over 500 kg/ms. Precipitable water though is expected to remain
under 1.0 inch. Multiple impacts will be associated with this
system, including possible high winds, heavy rain, and heavy
mountain snow. A warm tongue of air ahead of the front will allow
snow levels to rise to around 4000 ft along the Coast Range Saturday
morning. QPF values along the coast and western slopes of the Coast
Range around 2 to 4 inches will be possible through Sat night, while
ensembles show valley lowlands likely see around 1-2 inches of
rainfall. Snow levels along the Cascades are expected to hover
around 3000-3500 ft during the event. The current timing for the
Winter Storm Watch remains on track from early Saturday into early
Sunday morning. Snowfall accumulation is expected primarily over
3000 ft, with 1 to 2 feet of snow possible. Breezy conditions also
likely at higher terrain. A High Wind Watch has also been issued for
the coast. Models have come down somewhat from previous runs, now
showing possible wind gusts up to 60 mph from Friday evening through
Saturday morning.

A deep upper level trough will drop out of the Gulf of Alaska behind
the front Sat night and amplify offshore on Sunday. Expect snow
levels to fall again behind the front with mainly southwest flow,
which should maintain a cool and showery pattern.

&&

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY...The cool
and wet pattern will very likely continue through at least the
middle of next week as ensemble guidance shows strong agreement on
deep upper level troughing lingering over the West Coast. Therefore
maintained high PoPs across much of the area through the extended
portion of the forecast, with additional periods of mountains snow
likely during the first half of the week. Snow levels will gradually
come back down to around 1000-1500 feet through early next week as
colder air filters into the region. This may eventually yield some
greater winter weather concerns for parts of the coast range,
although the prospects for any eventual lowland snow concerns remain
more nebulous at this time. /CB

.AVIATION...06Z TAFs: At 04Z radar indicated scattered shower
activity over the area associated with northwest flow aloft.
Generally VFR along the coast and interior lowlands, except for
local MVFR associated with showers. The higher terrain, such as
the Oregon Coast Range, Cascades and southwest Washington Willapa
Hills will remain frequently obscured with MVFR or worse
conditions through Friday. Will need to watch for isolated IFR or
lower conditions overnight in fog should there be any prolonged
cloud breaks. At 04Z KHIO reported MVFR vis. Should see gradually
increasing MVFR conditions developing late tonight in the
interior valleys. VFR will be the more dominant category after
18Z Fri, except for the southwest Washington coast and coastal
valleys where MVFR is most likely to occur.

KPDX AND APPROACHES...VFR at the terminal as of 0430Z, but cigs
were 035 to 045. Not expecting much change through 12Z, but
cannot rule out brief period of MVFR. IFR or lower conditions are
possible in the Tualatin River Valley overnight through Fri
morning. Expect mainly VFR after 18Z Fri with cigs generally
035-040. Weishaar

.MARINE...Minimal changes to current forecast. Looking at
consistent conditions with seas around 11 to 13 ft at 12 seconds
through early Saturday morning. At 0430Z Fri wave heights were
generally 1-2 ft higher than guidance. Have nudged wave heights
for tonight and Fri up just a bit to account for the bias. Models
continue to advertise a very active cold front and associated
low pressure system passing to the north of the area but will
bring a southerly wind shift and an amplification of seas.
Expecting winds to quickly increase from the 15 to 20 kt with
gusts at 25 kt to around 30 to 35 kt with gusts up to 40 kt by
Saturday morning. Gale force wind gusts are possible although
models are shifting around on whether they will be widespread and
frequent or if they will be isolated. Have issued a Gale Watch
in response to those conditions.

As the southerly winds pick up, wind waves will too build. Seas
will be slightly slower to respond. Seas should build to around
16 to 18 ft at 13 to 15 seconds by late Saturday/early Sunday
morning. The GEFSWAVE Probabilistic Wave Height guidance suggests
a 40 to 60 percent chance of wave heights exceeding 18 ft Sun
afternoon through early Mon. Seas appear to reach their peak
heights around late Sunday night. May see localized waves up to
20 ft, especially in the far northern outer waters.
