Area Forecast Discussion

256 PM PST Fri Nov 14 2025


.DISCUSSION...Radar currently shows that the remaining morning
showers dissipated as the region dries out. A stationary front is
situated in Northern Washington state allowing for mid to upper
level clouds to linger around the region, with most places
receiving decks of 5000 to 8000 feet of SCT to OVC conditions.
The upper level pattern will become more zonal as the shortwave
departs the region, allowing for drier conditions going through
Saturday morning, save for some rain showers in the mountain
regions. As the pattern continues to become more zonal, pressure
gradient development allows for breezier winds to develop with
gusts up to 20 to 30 mph for most of the area through Saturday
morning.

The next widespread precip event will be driven by another
shortwave approaching the PacNW late Saturday through early next
week. Surface winds will shift towards the SW, allowing for
abundant moisture transport, increasing PoP chances across the
board at 40 to 70 percent. Snow showers will develop as snow
levels drop to 4500 to 5500 feet going through Monday morning.
Very little accumulation is expected with this system with
guidance suggestion up to a half inch in most places (60 to 80
percent chance). Precip will be on and off through Thursday as the
area is situated between two trough systems. Consequently, the
relatively drier conditions will allow for some effective
radiative cooling, lowering Min Temps midweek below freezing for
much of the area. Things become a bit more uncertain Thursday
onwards as some models disagree on how to handle the second trough
system, regardless a wet, rainy pattern is more than likely to
resume the later part of the week.

.AVIATION...Mostly VFR conditions through the period. DLS/YKM have a
30% probability of seeing VCSH between 00-04Z as well as DLS seeing
CIGs drop to OVC025 bring them to MVFR through the overnight hours.
YKM/PSC/ALW/PDT have a 30% probability of seeing overnight and
morning BR which will likely bring VSBY to 4SM and below.
BDN/PSC/YKM are both seeing winds above 10kts with gusts to 22kts
and they will see a decrease through the overnight period. CIGs will
flux between 5kft-10kft through the evening and overnight period as
well. CB/90
