Area Forecast Discussion
National Weather Service Seattle WA
805 PM PST Fri Nov 7 2025

.SYNOPSIS...Drier and warmer conditions will settle into
western Washington over the weekend as high pressure builds
overhead. A weak system will bring light rain to the region
early next week, with potential for a stronger and wetter system
to move into the Pacific Northwest towards the end of next
week.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...Previous
discussion...As high pressure begins to build inland, shower
activity will continue to taper off throughout the afternoon
today and skies will continue to slowly break out. Today will
give way to typical fall- like conditions with near normal
temperatures in the mid 50s and plenty of sun breaks. The
weekend will provide more of the same on Saturday and Sunday as
high pressure continues to build into the Pacific Northwest,
with a slight warming trend allowing temperatures to peak in the
low to mid 60s by Sunday. Light overnight winds, ample residual
moisture from recent rainfall, and decreased cloud cover
overnight are all conducive to areas of fog developing
overnight, with the best chances of widespread fog early
Saturday morning. Conditions will improve by the afternoon,
giving way to cloudy skies with plentiful sun breaks.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...A weak frontal system will
cross western Washington early Monday, bringing the next round
of rainfall to the region. While much of the lowlands will see
light amounts less than a tenth or two, the bulk of the moisture
will fall over the northwestern Olympic Peninsula and North
Cascades, where amounts could reach half an inch or more. Post-
frontal showers may linger into Tuesday with a few degrees of
cooling.

Forecast confidence decreases into the middle of next week, as
a low pressure system is set to deepen along the Pacific Coast
and push inland. Active and wet weather is set to return towards
the end of next week, but the exact details remain uncertain at
this time.

.AVIATION...VFR conditions prevail area-wide late this evening
with high clouds overhead with a few lingering low clouds over
the Cascades and South Sound areas. High clouds should thin out
a bit late tonight, allowing for areas of fog to develop in
spots early Saturday morning. The best chances will be at OLM
and around the South Sound, but 15-20% chances for LIFR
conditions are possible at all area terminals. These are
slightly lower probabilities compared to this afternoon. Too
much high cloud coverage and offshore flow may inhibit allowing
the surface layer to fully achieve saturation. Fog should burn
off later in the morning, giving way to another day of VFR
skies. Light southeasterly winds will become east to
northeasterly early Saturday morning around 5 kt or less except
through the Chehalis gap and the Strait of Juan de Fuca with
winds up to 10-15 kt.

KSEA...VFR this evening with high clouds overhead. Fog remains in
the forecast, however, probabilities have reduced into the 15-25%
range. Southeast winds 5-7 kt will become east overnight, 5 kt or
less, then becoming northeast 4-7 kt by Saturday afternoon.

.MARINE...Seas remain elevated across the coastal waters and
into the west entrance of the Strait of Juan de Fuca tonight.
Seas remain in the 12-14 ft range late this evening and should
continue to slowly subside into early Saturday. The current
advisory for the coastal waters runs through Saturday morning,
with seas likely to reach below 10 ft around midday. With
building high pressure over the area, expect some light offshore
flow to develop across the waters through the day Saturday.
This could bring low end advisory conditions with gusts to 25 kt
to the western Strait and portions of the coastal waters,
especially in the north and west of Grays Harbor where the
easterly winds tend to be enhanced. Will hold off on an advisory
given the somewhat marginal wind speeds and will continue to
evaluate the strength of this.

Otherwise, expect a lull in the active pattern continuing into the
weekend with high pressure building over the coastal waters. The
only exception may be some breezy winds near the western Strait
tomorrow with offshore winds developing. Otherwise, a splitting
front approaches late in the weekend with disturbances brushing the
outer coastal waters on the way to the B.C. coastline. Additional
disturbances may reach the waters early next week, though confidence
is low in timing any particular period of concern.

.HYDROLOGY...Minor flooding continues on the Skokomish River as
it slowly recedes.

Area rivers have all crested from this last heavy rain event
and will also continue to recede. At this time, forecasts show
additional systems will move into the area early next week,
however rainfall amounts generally look to remain light. The
next chance for heavy rain is not until the end of next week and
no new flooding is expected for the next seven days.
