Area Forecast Discussion
National Weather Service Pendleton OR
1000 PM PST Sat Jan 3 2026

.Updated for Aviation..

.AVIATION...
06Z TAFS...Except for BDN and RDM and possibly PSC conditions are
expected to be MVFR or IFR during much of the TAF period due to
low clouds, fog and or rain. Winds will mainly be 10 kts or less,
but due to some stronger winds aloft, LLWS is possible at PDT,
RDM, BDN, PSC through the overnight hours.

&&

.PREV DISCUSSION... /issued 258 PM PST Sat Jan 3 2026/

DISCUSSION...Latest visible satellite imagery depicts a trough
centered just off the coast of the PacNW. This trough will instill
SW flow aloft through the region, making for intermittent showers
and breezy winds through central Oregon and the base of the Blue
Mountains. Snow concerns will be limited until the midweek, as warm
air advection from this upper-level flow pattern will keep snow
levels generally elevated at above 5000 ft. This system also lacks
the moisture punch needed to bring precipitation to the lowlands, so
wind will be the primary sensible weather concern outside of the
mountains through the weekend.

While some hi-res guidance depicts a bullseye across the base of the
southern Blue Mountains for particularly gusty winds (isolated spots
of 40-60% wind gusts exceeding 45 mph, according the the NBM), opted
not to issue any wind advisories as impacts aren't expected to be
widespread and long-lasting enough to justify headlines. May need to
re-assess this later tonight, when guidance has winds ramping up
once again, but unless gusts start flirting with criteria along I-84
at the base of the Blues in particular, think it's better to hold
off and play the 'wait and see' approach for now.

This broad trough eventually shifts inland during the day Sunday.
Some of our higher mountain passes (namely Santiam) may see light
accumulating snow during the early morning hours, but otherwise
precip is expected to taper off throughout the day Sunday, with
Monday looking dry as drier, more northerly air filters in. Tuesday
onward becomes more active, however, as global models depict a
return to a progressive westerly pattern that will support
persistent showers across our mountain zones. With colder air coming
in, snow levels are expected to drop down to the 1500-3000 ft range,
allowing for our mountain passes to receive a steady dose of snow
through much of the rest of the work week. Rain-shadowing looks to
be strong enough to preclude any decent precip chances for the
lowlands (confidence 30-40%), but headline-worthy snow looks very
likely (80-90% confidence) across both the Cascades and eastern
mountains starting around Tuesday. 74

AVIATION...With this next system arriving, KDLS/KYKM
will continue having low clouds through Sunday morning, making them
MVFR. However, KYKM may become IFR this evening into overnight
hours. The remaining sites will be VFR, but KPSC could drop to LIFR
around 05Z due to lingering low clouds. Light rain will develop over
KDLS/KRDM/KBDN/KYKM during evening hours as this system passes
through (30-40% chance). KPDT/KRDM/KBDN/KPSC may have breezy
sustained winds of 12-20kts with gusts at 20-30kts for these evening
hours. However, these gusts may return Sunday morning hours up to 25
kts (<40% chance). Thanks to the south-southwesterly wind aloft, low-
level wind shear could continue with winds at 30-55kts. Feaster/97
