Area Forecast Discussion
National Weather Service Seattle WA
338 PM PST Wed Nov 26 2025

.SYNOPSIS...
A frontal system will push through the area this afternoon for
another round of precipitation. Shower activity will continue
into Thursday with the potential for breezy conditions
throughout the evening. Conditions will begin to calm and dry
out heading into the weekend.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
Latest radar imagery shows shower activity pulsing up from the
south and starting to approach our area. Rain will start for
most of the area starting later this afternoon and evening as a
frontal system spins offshore. High temperatures this afternoon
staying in the low to mid 50s across the region, with overnight
lows in the low to mid 40s.

Widespread steady rain will continue overnight and into
Thursday as this low takes its time offshore. It looks like
Thanksgiving day will have showers on and off throughout the
day, with most of the area seeing precipitation - which could be
locally heavy at times (areas in the Olympics and Cascades).
Along with widespread precipitation, winds will be breezy at
times, especially for areas along the coast and for portions of
the interior. Rain and wind both took to taper overnight
Thursday into Friday, with a drying trend looking to start up
over western Washington.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Upper level ridging over the eastern Pacific looks to dry out
conditions throughout the day on Friday and heading into the
weekend. Some of the ensembles are hinting on a few weak
impulses on Saturday that could spark some light showers across
the area, but it is looking rather weak if it does materializes.
Otherwise, conditions look to be mainly dry for the weekend,
along with overnight temperatures getting cooler. Overnight
temperatures on Saturday look to get down to the upper 30s, even
mid 30s early Sunday morning. Areas near the water likely will
be cooler overnight, and especially if cloud cover clears up,
could anticipate temperatures dropping a bit more.

The upper ridge starts to shift eastward on Monday which
leaves room for a weak frontal system to potentially cross over
western Washington for another round of light rain. Ensembles
are still trying to key in on this feature, but for now will
leave mention of showers each day through Wednesday.

.AVIATION...
The air mass is stable with light surface winds and mostly
LIFR/IFR ceilings. Rain will increase in coverage tonight as a
warm front lifts north through western WA. Showers will continue
into Thursday with low pressure shifting inland.

KSEA...Low clouds will persist through much of the day with
cigs in IFR to MVFR range. Steadier rain starting 00-06Z tonight
and continuing into Thursday. SE/E wind around 5 kt.

&&

.MARINE...
A bit of lull in the winds during the day today in between
systems, but it`s worth noting that seas over the coastal waters
remain quite choppy with a dominant period around 7-9 second.
Conditions continue to hold just short of advisory criteria,
however. Another strong front will bring another round of
advisory strength winds Thursday, along with seas building
significantly into the 15-17 ft range (particularly the outer
and southern coastal waters). At this point gales should remain
over the offshore waters and the current SCA covers the coastal
zones well, but occasional gusts to 35 kt can`t be ruled out
beyond about 35 NM from shore. Late in the week, high pressure
begins to rebuild over the coastal waters into the weekend. Will
need to monitor the strength of any northeast flow developing,
but at this point strong Fraser outflow isn`t particularly
likely.

&&

.HYDROLOGY...
Another frontal system will bring a round of rain to the region.
Snow levels will remain above 5000 feet through Thursday
evening, leaving the majority of the precipitation falling as
rain. However, with expected rainfall amounts holding steady and
topping out mostly in the 2 to 2.5 inch range with this system,
confidence is increasing that we will not see any river flooding
impacts. As a result, the flood potential outlook has been
expired for Mason County.
