The local office's own words before this wind advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Pendleton, OR wrote its last area forecast discussion before this wind advisory went out at Dec 24, 9:47 AM PST, 3 hours 43 minutes earlier.

Area forecast discussion, Dec 24, 9:47 AM PST, 3 hours 43 minutes before
Area Forecast Discussion
National Weather Service Pendleton OR
947 AM PST Tue Dec 24 2024

.Updated for Aviation...

.AVIATION...
18Z TAFS...TAFS were generally MVFR or VFR this morning. Brief IFR
conditions are possible as additional rain moves through.
Improvement to VFR is expected at all sites by this
afternoon/early evening as the area of rain moves out of the
region. VFR conditions should hold through the day Wednesday ahead
of the next system. WInds should generally be 10 kts or less.

&&

.PREV DISCUSSION... /issued 253 AM PST Tue Dec 24 2024/

SHORT TERM...Today through Thursday...Highlights for the morning
forecast package include the current High Wind Warning and Wind
Advisories for the Blue Mtn Foothills (zones WA30, OR507, and
OR508) and the Grande Ronde Valley (OR49) as well as the issuance
of a Winter Weather Advisory for the east slopes of the WA
Cascades (zones WA522 and WA523).

Winds peaked out early this morning at 70 mph from the east along
I-84 near Cabbage Hill. This is the windiest spot along the
foothills, and there have been reported gusts to 65 mph near
Mission. South-southeast winds gusting to around 45 mph have been
observed in the Grande Ronde Valley. The WA foothills and the
southern foothills of OR are not as strong, but there are gusts
35-40 mph in a few locations. If the southern foothills (OR508) continue
to shows breezy winds gusting only to 25-35 mph, then the advisory
may be cancelled sooner than the 7 AM end time.

There are two upper level frontal systems impacting the PacNW
during the short term. Satellite shows a deep low centered off the
BC coast sending a moist southerly flow across WA/OR/ID. For our
CWA, we've received rainfall amounts up to 1/4 inch over the past
12 hours. There is a strong AR off the coast that weakens as it
penetrates inland, but both GEFS and ECMWF ENS have high
probabilities of at least a 250 kg/m/s IVT over the forecast area
this afternoon (probs drop off significantly for 500+ IVT). The
00Z HREF mean QPF with this system generally ranges from 0.25-0.5"
(0.5-0.75" along the Cascades), including the Lower Columbia
Basin and surrounding valleys. Snow levels are very high this
morning across central and northeast Oregon with most elevations
below 6000 feet reporting rain. Snow levels along the eastern WA
Cascades are about 3500-4000 feet, but this area is not seeing the
moisture conveyor belt like areas to the east. Snow levels will
lower with the passage of the trough this afternoon and tonight,
but precipitation will also taper off as well. Therefore, no
winter highlights are planned with this system.

The next system arrives late Christmas afternoon and Christmas
night as a moist southwest flow. This system will likely bring
heavy snow to the WA/OR Cascades where our neighboring offices
have Winter Storm Watches in effect. The challenge, however, has
been snow levels for the east side. Snow levels will increase,
and most of the eastern valleys of the OR Cascades below 4500 feet will
observe precipitation as rain. For the east slopes of the WA side
of the Cascades, snow levels will be slower to increase and there
will be moderate to heavy snow at elevations above 3000 feet.
High confidence that 5-10" of snow will be observed which meets
advisory criteria. The northern Blue Mtns above 4500 feet may also
have moderate snow Christmas night. This includes Tollgate and
Bluewood. Confidence was not enough to warrant an advisory and
will leave to the day shift to analyze a little more. Additional
wind highlights may be in order for the Grande Ronde Valley to the
Blue Mtn Foothills, as it will be very windy Christmas night.
Confidence is about 70% for at least advisory 45-55 mph gusts to
be met. Since we currently have highlights for today's system,
it's best to hold off to avoid confusion. Wister/85

LONG TERM...Thursday Night through Tuesday...

Bottom Line Up Front

1. Continued Wave train of upper level systems

2. Widespread rain and mountain snow daily

3. Above average temperatures through Sunday

The long term will continued to be characterized by active weather
with continuous upper level systems making their way across the
PacNW darn near everyday through the weekend. Each system will bring
widespread rain as well as mountain snow each day with the strongest
systems occurring Thursday night into Friday night and returning
again Saturday night through Sunday night. The first few systems
will bring southwesterly flow which will keep temperatures slightly
above normal and snow levels a bit higher. The later systems will
bring cooler temperatures over the weekend and the start of next
week. With these continued systems bringing elevated amounts of rain
as well as snow, hydrologic concerns could arise by the weekend.

Deterministic models show a wave train of systems making their way
across the region. Clusters show that the main variance between the
models to be primarily with the position of the axis, however, the
CW3E AR landfall tool shows over 80% probabilities that the max of
the atmospheric rivers will make landfall between 40-50 degree
latitudes. In other words, directly across our region. Raw ensembles
show over 80% probabilities of elevations above 4000 feet seeing
between 1-5 inches of snow with higher elevations seeing near 10
inches with 50-70% probabilities for Thursday night through Friday
night. With the system stalling over the region Thursday night
through Sunday afternoon, raw ensembles show over 80% probabilities
of yet another 5-10 inches along the east slopes of the Cascades
above 4000 feet as well as and addition 5-8 inches for the Blues and
again Sunday. However, models show the axis to shift a bit farther
north allowing the OR Cascades to see higher snow levels so any snow
there will fall above 5000 feet Saturday then dropping again
slightly Sunday. The system that will approach Sunday night will
approach from the northwest bringing with it cooler temperatures.
This will drop snow levels to between 2500-3000 feet. Snow is
expected to fall at these levels with 80% of the raw ensembles
showing the eastern mountains seeing 0.5-2 inches, lower east slopes
of the Cascades of OR & WA seeing between 0.5-2.5 inches while the
upper east slopes as well as the Blues seeing 4-6 inches with higher
amounts above 4500 feet (Tollgate, Ski Bluewood) seeing 7-9 inches.
Monday and Tuesday will settle a bit with only mountain snow showers
lingering.

As for the lower elevations, there is a 20-30% probability of
central OR seeing 0.25 inches of rainfall, 30-40% for the Basin and
50-80% for the foothills, Gorge, John Day Basin and Wallowa Valley.
Saturday there will be continued low elevation precipitation with 60-
80% probabilities for the Basin seeing an additional 0.10-0.20 inches,
central OR, Gorge and foothills seeing an additional 0.25-0.35
inches and the lower east slopes seeing 0.35-0.45 inches. Sunday
will see yet another round of precipitation with 30-60%
probabilities of yet another 0.20-0.30 inches of rain through the
lower elevations and 0.30-0.50 along the lower east slopes. Monday
and Tuesday, much of the precipitation will remain along the higher
elevations with light rain of 0.01-0.05 for the lower elevations.
With the amount of snowfall expected as well as warm rain on top of
it, the forecasted river gauges do show an increase rise for some
rivers through the Blues and Cascades. As of now they are remaining
below action stage. However, Naches at Cliffdell and Umatilla near
Gibbon are showing these rivers could reach 0.5-1 foot below action
stage come Sunday morning. This will continue to be closely
monitored as the events continue to draw near.

EFI shows temperatures to be slightly above normal through the
Basin, Gorge and foothills before leveling off to near normal Sunday
night after the cold front passes. NBM shows temperatures to average
in the upper 40s to low 50s across the lower elevations with higher
elevations in the 30s. After the cold front passes Sunday afternoon,
temperatures drop into 40s across the lower elevations with sub-
freezing temperatures along the higher elevations. We will also see
the return of sub-freezing overnight lows across the lower
elevations as well.

AVIATION...12Z TAFs...All TAF are VFR except ALW which is MVFR. ALL
TAF sites will see a category change through the period due to low
CIGs lingering after the system moves overhead. Confidence in timing
of low CIGs is low/moderate (30-50%), however, models show them
moving over DLS/PDT near 12Z PSC near 15Z, BDN/RDM near 15Z The low
CIGs will drop all sites to LIFR and MVFR respectively. Winds will be
light and variable through the period. Bennese/90
