.UPDATED AVIATION...DLS/PSC are currently VFR but are expected to
drop to MVFR over the next few hours as the low clouds ahead of
the system make their way across the region. Snow will grace a
large portion of the TAF sites through the period bringing varying
flight categories. Snow is being reported across RDM/BDN/YKM/PSC.
BDN/RDM will see 2-5 inches (70-80% probabilities) while YKM/PSC
will see 0.10-0.25 inches (30-40% probabilities). PDT/ALW will see
snow as well although timing for those TAF sites is a bit more
difficult to sus out. However, snow is expected to begin between
now and 08Z with totals nearing 3-4 inches (60-80% probabilities)
or more through the period. Winds will remain light through most
TAF sites below 10 kts with the exception of PSC seeing 15 kts
with gusts to 25 kts through the early overnight hours. Confidence
in the forecast is high (80-90%). Bennese/90

.PREV DISCUSSION... /issued 242 PM PST Thu Feb 6 2025/
SHORT TERM...Tonight through Saturday...Satellite and surface
observations this afternoon show layers of mid to high level cloud
cover spreading across the forecast area from the south.
Meanwhile, portions of the Columbia Basin and adjacent valleys are
reporting low to mid layer stratus decks in addition to higher
cloud decks. Little to report weather wise as conditions have been
mostly dry, however, some higher elevation locations north of the
Yakima valley and across the northern Blues have reported light
snow, which has resulted in a skiff of snow at best.
This afternoon through early tomorrow morning, a surface low
that will track across northern CA and southern OR will push a
warm front boundary across central and northeastern OR, which
will be followed by a shortwave passage into early tomorrow
afternoon. The combination of these synoptic systems will result
in increasing snow chances across central and northeastern OR and
portions of far southeastern WA through early tomorrow afternoon.
there remains high confidence (75-95%) in snow accumulations of 2
to 5 inches across the OR Blue Mountain foothills, central OR,
John Day Basin, the Grande Ronde valley, and the Wallowa valley; 1
to 4 inches across north central OR, OR Columbia Basin, and the
WA Blue Mountain foothills; 4 to 7 inches across the Blue
Mountains and Ochoco John Day Highlands. Winter Weather Advisories
and Warnings have been issued for these areas through 4PM Friday
afternoon. The precipitation line is expected to quickly drop off
north of the Horse Heaven Hills and the Simcoe Highlands, with a
snow accumulations less than 2 inches expected in these areas.
The track of the surface low into southern ID will also result in
surface pressure gradients tightening from the Columbia Basin to
the Lower Treasure valley. This will result in breezy northerly
winds developing through the Grande Ronde valley, north/south
valleys of the Wallowa mountains, and along ridges in the Columbia
Basin, while westerly winds will develop on the north side of the
Northern Blues and along ridgetops around the Strawberry
mountains.
The shortwave trough will quickly exit the region Friday
afternoon resulting in a lull in precipitation into Saturday
morning. While conditions will be mostly dry Friday night, they
will also be very cold across in the high and intermountain
valleys across the Blues and Ochocos, with temperatures in the
single digits to low teens expected Saturday morning.
Dry conditions will not last long Saturday morning as another
shortwave trough will track down the BC coast line and gradually swing
across the PacNW through Saturday evening. With cold conditions
in place, snow levels will be at or below the surface again,
resulting in wide-spread light snow chances across the mountains
and many of the lower elevation locations outside of central OR.
That said, the Columbia Basin/Gorge and the adjacent valleys will
see at least a dusting of snow with around 0.5 to 1.5 inches in
the John Day Basin, northern Blue mountain foothills, and the
Grande Ronde valley. Across the Cascades, snow amounts will
generally be 2 to 4 inches. However, a more westerly component to
winds aloft as the shortwave approaches will result in upslope
enhancement of snow accumulations across the northern Blues,
resulting in 4 to 6 inches of accumulations by early Sunday
morning (confidence 60-75%). Lawhorn/82
LONG TERM...Sunday through Thursday...
1) Mountain snow continues.
2) Slight chance for lower Columbia Basin light snow.
3) Extreme cold temperature mid-next week.
High confidence (>85% chance) remains that troughing will persist
through the entire extended period, according to both GFS and ECMWF
ensemble guidance. N/NW flow aloft will keep precip chances down for
areas of the lowland, but mountainous areas will see the greatest
PoP (40-60%) until Wednesday morning. Ensembles are in good
agreement that the trough will dig from Canada to the PacNW. The GFS
and Euro begin to diverge in terms of agreement as we head into
Tuesday and beyond. Euro shows the trough digging deeper into the
PacNW than the GFS solution would. Light precip chances beyond
Tuesday for the lower mainlands remain low (20-40%) and higher at
around 50-70% for the mountainous areas. Accumulation is expected to
remain very minimal (<.02 inches) for the entire area.
Temperatures will be the main issue for this period. Guidance shows
the cooling trend going through Wednesday, dropping -15 to -25
degrees below normal. The NBM shows highs Sunday for the Columbia
Basin in the mid to upper 30s then dropping overnight to the low-
20s. Higher elevations, including central OR, will see min temps go
into the low teens to single digits. Temps will continue to trend
down through Tuesday night to Wednesday morning, which will be our
coldest period during the extended. NBM is showing by the time
Tuesday rolls around, highs will drop to the mid-20s to low 30s in
the Columbia Basin, but higher elevations will only see low to mid
20s. The low temp going into Wednesday morning are when we have the
coldest temps that we need to pay attention to. NBM currently shows
single digit temperatures up into the mid teens for the Columbia
Basin and temperatures just below zero for the higher elevations,
including areas around Central OR.
Breaking it down by temperature, the entire CWA (minus the upper
Columbia Basin and areas around The Gorge) shows a high chance of 60-
100% of reaching less than 10 degrees. Areas around The Gorge, Tri-
Cities, and the upper Columbia shows a much lower chance of 20-40%
of reaching below 10 degrees. Dropping the threshold to less than 0
degrees, the Foothills show a 10-30% chance of reaching this
threshold, while higher elevations (including Central OR) still give
it a 30-60% chance of reaching below zero temperatures.
More monitoring is required to see if temperatures reach Cold
Weather Advisory levels (-10 degrees or below), as NBM show slight
chances (15-35%) for the Blue Mountains, Mountain Valleys, and south-
central OR.
