The local office's own words before this storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Portland, OR wrote its last area forecast discussion before this storm warning went out at Oct 22, 9:05 PM PDT, 5 hours 42 minutes earlier.
Area forecast discussion, Oct 22, 9:05 PM PDT, 5 hours 42 minutes before
Area Forecast Discussion
National Weather Service Portland OR
905 PM PDT Fri Oct 22 2021
.SYNOPSIS...Expect a very active weather pattern to bring valley rain
and high mountain snow every 12-24 hours through early to mid next
week. Strong winds will be possible along the coast Sunday.
Additionally, high incoming ocean swell will bring a threat of
coastal flooding.
&&
.SHORT TERM...Tonight through Monday...Residual showers and isolated
thunderstorms continue to push northward over the near coastal waters
this evening. Expect these showers to continue to dissipate through
tonight.
Over the next 72-96 hours expect a rather active pattern as multiple
storm systems move across the region. The first of these systems
will be a shortwave trough from the Gulf of Alaska that will drop
southeastward into the area, which will maintain elevated
precipitation chances across the region through Saturday night.
Attention remains primarily focused on the next explosive event on
Sunday. Models and their ensembles are in moderate agreement that
low pressure near 138W and 43N will start to develop Saturday
afternoon with rapid bombogenesis taking place within the following
24 hours. Peak intensity looks to be around 940 mb to 945 mb early
Sunday morning near 132W and 46N. It should be noted that anything
sub-950 mb would result in the lowest pressure observed in the
northeast Pacific in the vicinity of 130W and 45N in recorded
history. There have been deeper low pressure centers observed
elsewhere in the northern Pacific closer to the Aleutian Islands and
Gulf of Alaska.
While the central pressure spread of the low seems to be narrowing,
there remains a lot of uncertainty as to the positioning and speed
of the low. The overall track looks to be toward the Olympic
Peninsula. However, the models still are unsure as to how fast the
low will move towards the NW portion of CONUS. The majority of the
GFS members bring it more towards the Olympic Peninsula, with the
weakening low making landfall late Monday night. The ECMWF members
have the low moving very quickly and making landfall around
Vancouver Island by late Sunday night/early Monday morning. The
Canadian is different in timing only with landfall around Vancouver
Island by Monday morning.
Either way, a large building west-southwesterly swell most likely
somewhere on the order of 25-30 feet will push onto the coast late
Sunday into Monday. This will result in combined seas building
towards 30-35 feet. As a result, expect very high surf that could
result in property damage along the coast Sunday evening/night and a
very dangerous sneaker wave threat lingering into Monday.
Extreme caution should be used by anyone venturing onto area beaches
Sunday and Monday. Jetties, logs and anywhere near the surf zone
should be avoided. As a result, we have issued a Coastal Flood
Warning, which includes a very high surf threat, starting Sunday
evening and continuing through Monday night.
While there remains uncertainty in the general track and speed of the
low, winds are a concern for Beaches and Headlands as well as areas
along the I-5 corridor. Gusts Sunday evening and night along
beaches/headlands are expected to be in the range of 55-65 mph, with
coastal communities 45-55 mph. We have issued a High Wind Watch for
these locations. Areas along the I-5 corridor/Willamette Valley are
expected to see gusts between 30-40 mph through a similar time
period. While these wind gusts do not meet Wind Advisory criteria,
we are issuing one for expected impacts, such as power outages,
downed tree limbs, and similar impacts.
/42
No changes for this part of the short term discussion...Finally, a
sizable (by our standards) coastal tornado threat will exist most
likely Sunday afternoon and evening, that appears at least on par to
Oct 14th 2016 when we had several low topped supercells move onto the
Oregon coast. 10/14/16 produced a tornado in Oceanside and an EF2
tornado in Manzanita. All available model guidance suggests similar
500mb temperatures to 10/14/16 with 500mb temperatures running in the
-24 to -26C range over the waters and along our coast Sunday
afternoon and evening. With sea surface temperatures around 57F, this
should result in MLCAPE values between 100-200 J/kg and SBCAPE values
closer to 500 J/kg. Strong deep layer shear, ~50 kt of wind at 1km
and veering winds within the lowest 1km of the atmosphere due to the
low pressure to our northwest will promote strong rotation with any
showers and thunderstorms that develop. 0-1km helicity values appear
likely to exceed 200 m2/s2 in the vicinity of the coast.
The main uncertainty with this event will be where do storms have
enough of an onshore component to actually push onto the coast.
Given the projected low pressure position, the steering flow will be
nearly south to north along the Washington coast, but much more SW
to NE farther south along the north-central Oregon coast, and thus
storms should have an easier time pushing ashore along the central
and north Oregon coast. However, there are certainly scenarios still
in play that result in the threat expanding northward to include the
south Washington coast. For now, it's best for anyone with interests
along the central & north Oregon and south Washington coasts to pay
attention to the forecast for Sunday and make sure they have a
reliable way to receive warnings.
/Neuman
.LONG TERM...Monday night through Friday...Ensemble guidance for the
first part of the upcoming week looks to be in good agreement. 500 mb
heights are expected to build over the CWA, with a weak warm front
lifting over the region with will maintain a rather wet pattern
through at least the start of the upcoming week. The middle of the
week looks to be a transition period, which might provide a brief
reprieve from all of the precipitation, although, confidence is low
at this time. Wednesday night/Thursday our next weather maker in the
form of a weak to moderate west-to-east oriented atmospheric river
will likely impact the Pacific NW. Models are still showing a
significant amount of uncertainty as to where this atmospheric river
will be pointed, as some guidance has it focused towards the Olympic
Peninsula while other model families have it focused towards the
Central Oregon coast. Given that there remains significant
differences have chosen to follow NBM guidance, which does keep PoPs
elevated through Friday.
/42
&&
.AVIATION...Showers continue to diminish this evening with VFR
prevailing. But KONP continues to be the outlier with IFR conditions.
Also there are a few thunderstorms moving northward about 40nm
off the central coast. Model soundings indicate the chances for
thunderstorms will end around 06Z
Will see clouds increase again overnight as the next round of
rain spreads into the area. Expect to see MVFR conditions return
to the coast by 08Z, then over the interior after 10Z through
about 20-22Z Sat. Think KONP will remain IFR through about 12-15Z as
south to south-southwest winds switch over to southwest in that
time frame, which should mix the lower layers some.
Precipitation diminishes rapidly Sat afternoon as the low to mid
level winds turn offshore as a storm system strengthens offshore.
Rain spreads across the area Sat evening.
For detailed regional Pac NW aviation weather information, go
online to: https://weather.gov/zse
KPDX AND APPROACHES...VFR prevailing with a few showers in the
vicinity. Next system will bring rain around 08Z then increasing
chances for MVFR conditions after 10Z Sat. HREF guidance
indicating highest chances for MVFR 13-19Z Sat. Rain tapers off
to showers around 18Z Sat. Model guidance shows around a 50-60%
chance that clouds will scatter tomorrow afternoon before more
low clouds move in during the late evening hours ahead of the
Sunday storm system.
/mh -Bumgardner
&&
.MARINE...The lead story remains the Sunday-Tuesday system. Until
then, a gradually weakening front will cross the area overnight
and hold enough together to bring low end gale gusts to the
waters. Winds then ease Saturday afternoon and evening. Seas
will remain in the lower teens.
Large scale picture coming together now for the very strong low
set to develop well offshore. Models all agree on the central
low pressure falling below 950 mb. Fortunately the center will
remain outside of 130 W until the center nears the latitude off
the Olympic Peninsula. This, in general, keeps the stronger
winds focused over the outer edge of the outer waters. That said,
gales arrive on the waters after midnight Saturday. There is a
brief period around daybreak Sunday where gusts could reach 45-50
kts, especially over the outer waters. Gales then continue with
another short burst of 45-50 kt wind gusts possible mid to late
Sunday evening. Given those periods, have issued a storm watch
for this event instead of a gale watch. There is a distinct
probably we end up with the gale warning but a minimal shift in
the position and details could bring higher gusts across all the
waters during these times. Winds will then ease, dropping below
gales Monday afternoon.
This southwest to north-northeast track of the low will generate
a dynamic fetch of wind which appears to be capable of generating
large seas. By the time these seas reach our waters, combined
seas will only have decayed down to 30-35 feet at the highest and
25-30 feet at the lowest. The seas will trail the peak winds by
6-12 hours building above 20 ft by later Sunday afternoon,
peaking after midnight Sunday night, then slowly subsiding and
falling below 20 ft near daybreak Tuesday morning.
Conditions further ease Wednesday though another low will brush
the waters with westerly winds 15-20 kts and also keep seas in
the mid-teens. /JBonk
