Area Forecast Discussion
National Weather Service Seattle WA
827 PM PST Mon Dec 15 2025

.SYNOPSIS...An atmospheric river will continue to produce
impacts across western Washington through the week. The first
round of rain will wrap up tonight, with a second system moving
through Tuesday into Wednesday. This second system will bring in
cooler air, along with mountain snow, and additional rain to
the lowlands and mountain slopes. An additional system will pass
through Thursday into Friday, with lighter precipitation into
the weekend. Winds will continue to diminish tonight, with
another round of gusty winds arriving Tuesday night into
Wednesday.

&&

.SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/...This afternoon:
the first round from this atmospheric river continues across
western WA this afternoon. The cold front is progressing
through, with the mode shifting more from stratiform
precipitation to convective/showery activity. The atmosphere
remains conditionally unstable going into the afternoon
(especially in the Cascades and the coast). A few showers have
formed in these areas that have elevated quickly. There remains
a 20% chance of thunder going into the evening. The heaviest of
these showers/storms may produce rainfall rates up to 0.25"/hr
(which may be a concern for a few of the newer burn scars in the
Cascades). Aerial and river flooding continue to be an issue
with the heavier precipitation that fell earlier
today/yesterday. Please see the hydrology section below for more
details on flooding potential and current impacts. Lastly,
breezy winds continue with this first system, and a wind
advisory remains in effect until 10 PM as winds decrease later
tonight. The saturated soils will produce more widespread power
outage impacts (in relation to trees and power lines potentially
coming down).

Tuesday/Wednesday: A second frontal system will bring another
round of precipitation across the region. The bulk of this
precipitation will arrive late Tuesday morning, and continue
through Wednesday afternoon. The cold front with this system is
expected to bring cooler air down with snow levels dropping from
6,000 ft down to 2,000 ft. There remains a 10-20% chance of
thunder with this system, especially along the coast.

Impacts: Winds will pick up Tuesday into Wednesday, decreasing
Wednesday afternoon. The ensemble guidance between the HREF/REFS
and NBM kept the most likely wind impacts in the advisory range.
The high wind watch was replaced with a wind advisory through
the period. Southwest winds of 15 to 30 mph are expected in the
advisory areas, with gusts up to 45 to 55 mph (highest gusts
along the Pacific Coast).

Rain will transition to snow in the Cascades/Olympics late
Tuesday night/Wednesday morning. Some model discrepancies remain
with how quick the transition will take place, but models
relatively agree on set amounts between the north Cascades, and
the south Cascades/Olympics. The north Cascades will see warning
amounts of snow with 10-16 inches at Stevens Pass, and higher
amounts at some of the mountain peaks. The south Cascades and
Olympics will likely see advisory amounts, with 6-10 inches at
Snoqualmie and White Passes. Breezy winds up to 35 mph in the
passes may reduce visibilities and near-blizzard like conditions
at times (especially with the heavier snow). If traveling over
the passes, check road conditions prior to traveling.

For all remaining lowlands: rain will push through late Tuesday
morning through early Wednesday afternoon. The heaviest of the
precipitation rates remain in the mountains, but the lowlands
may see rates approach 0.10"/hr (lighter than previous systems).
Additional rainfall amounts of 0.75-1.25" are expected in the
interior, with the coast seeing around 1.00-1.25".

In addition to rain and wind, landslide risk will remain high
through the week due to saturated soils from last week (and this
week's) rainfall across the region. Strong waves along the
Pacific Coast will be possible at times today through Wednesday
as waves of 15 to 19 ft move up to the coast. High surf is not a
concern at this time.

Temperatures will remain above average Tuesday, with highs
remaining in the mid 50s. They will dip into the 40s on
Wednesday. The lows overnight will drop from the mid 40s
tonight, to the low 40s Tuesday and Wednesday night.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...A third system will move
across the region Thursday into Friday. The snow levels will
remain around 2,000 ft with this system, adding additional snow
to the passes. QPF will be heavily concentrated in the Cascades
and Olympics, but amounts overall are on the lighter side
compared to the previous two systems (0.50-1.00" in the
lowlands, and 1-3" in the mountains). Light QPF will continue
through the weekend, with no additional impacts expected. The
ensembles favor a cooler pattern going into the holidays next
week, with a slight chance of wetter conditions.

.AVIATION...
Conditions continue to improve late this evening as shower coverage
continues to diminish and cloud cover is breaking up across western
Washington. However, it will not be long before the next system
arrives Tuesday morning bringing more rain, wind, and reduced flight
conditions tomorrow. Strong southwest flow prevails aloft.

Winds have largely begun to diminish with winds around 8 to 12 kt
and gusts below 20 kt. Winds will continue to ease down to around 10
kt or less tonight before beginning to increase once again to around
10 to 20 kt with gusts 20 to 30 kt after 20Z Tue at most terminals.
Gusts of up to 40 kt cannot be ruled out, especially along the coast
after around 00Z Wed.

VFR conditions have returned to most area terminals this evening.
However, isolated instances of high-end MVFR ceilings cannot be
ruled out through this evening. More widespread MVFR to IFR ceilings
are expected to build back in this morning around 10-15Z Tue along
with chances for rain and showers and continue through the remainder
of the TAF period. Limitation in visibility will be possible,
especially with the push of heavier rain after 00Z Wed.

KSEA...Rain and winds have allowed to a return to VFR conditions
this evening. Periods of higher-end MVFR through remain possible
tonight. Ceilings lowering back to MVFR are expected after 12-15Z
Tue as rain chances increase as well. Southwesterly winds begin to
ramp up as well shortly thereafter. Gusts up to 30 kt possible after
18-21Z Tue. Gusts up to 35 kt, as well as vis limitations in heavier
rain possible after 00Z Wed.

.HYDROLOGY...Rain will ease tonight before another front
reaches the area later Tuesday into Wednesday increasing
precipitation rates. Cooler air moving into the area Tuesday
night adds some uncertainty to the river levels. Current
forecasts have snow levels dropping to 2000 to 2500 feet by
Wednesday morning. The front Tuesday night into Wednesday has
more moisture than the todays system but the cooler air will
keep some of the moisture in the mountains in the form of snow.
This combination makes for tricky river forecasting.

The second round of precipitation will drive additional rivers
above flood stage with major flooding possible along the Skagit
and moderate flooding for the river flowing out of the Central
Cascades like the Skykomish, Snoqualmie and Snohomish.

A flood watch is in effect through Thursday afternoon across the
lowlands.

With a couple more rounds of precipitation the landslide threat will
remain very elevated through Thursday.
