.SYNOPSIS...
Front dissipating over Western Washington later today into
tonight. Upper level ridge building tonight and Saturday will
not be strong enough to keep a warm front out of the area.
Trailing cold front arriving Sunday. Another warm front will
reach the area Monday. Upper level ridge building Tuesday will
remain over Western Washington into next weekend giving the area
unseasonably warm temperatures.

.SHORT TERM /TODAY THROUGH SUNDAY/...
Updates to the aviation discussion have been included otherwise no
other changes this morning. 27
Satellite imagery shows warm front off to the northeast with a cold
front offshore early this morning. Even with a break in the rain the
low levels of the air mass are saturated. Fog has formed in the
South Puget Sound and Southern Hood Canal with visibilities a mile
or less. Mild outside this morning with temperatures at 3 am/11z in
the mid 40s to mid 50s.
Wet and mild pattern continuing for the next couple of days.
Cold front offshore moving into the area late this afternoon and
tonight. Rain on the coast this morning will spread inland by
late morning. Rain all areas in the afternoon. Another breezy
day for the Northwest Interior with southeasterly winds 15 to
25 mph with gusts as high as 40 mph. Snow levels well above pass
levels, 5000 feet rising to near 7000 feet. Highs in the lower
to mid 50s.
Cold front dissipating over Western Washington this evening as
upper level ridge begins building over the area. Another warm
front offshore getting deflected a little by the ridge but close
enough to create a chance of rain on the coast early Saturday
morning. Another mild night with lows in the mid 40s to lower
50s.
Saturday morning a race between the building ridge and the warm
front. At this point it does not look like the ridge will be
strong enough to prevent rain over the northern portion of the
area and at least a chance of rain over the southern portion in
the morning. Drying from the south in the afternoon as the warm
front lifts north to near the Canadian border. This puts Western
Washington in the warm sector so even with plenty of cloud
cover highs in the mid to upper 50s with lower 60s in the warmer
locations.
Short break in the rain continuing Saturday evening before rain
out ahead of the next approaching cold front reaches the coast
overnight. Mostly cloudy/cloudy skies will keep lows in the 40s.
Cold front moving into the area Sunday getting February off to a
wet start. Snow levels dropping a little but still in the 4500
to 5500 foot range. Highs in the lower to mid 50s.
The threat of coastal flooding will return this weekend into
early next week as we reach a new moon Sunday. At this time,
the weather does not look to exacerbate the flooding, with only
minor impacts currently expected primarily for sensitive areas
along the coast, in the Puget Sound and Salish Sea.
Some stats as we come to the end of the month. This short run
of above normal temperatures the last few days will push the
Seattle average monthly January temperature above normal by
less than a degree. If it seems like it has been warmer then
that it is probably because it has been warm the last three
months. The Seattle average temperature for November 2025
through January 2026 is going to end up being the 2nd warmest in
82 years surpassed barely by November 2018 to January 2019.
Counting the next two days there will be 55 days with highs 50
degrees plus in Seattle between November and January. The normal
is 39 days. The most recorded is 58 days, November 2018 to
January 2019 and November 2002 to January 2003. Felton

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Like its predecessor the cold front will dissipate over Western
Washington Sunday night. Upper level ridge beginning to build
Monday but not fast enough to prevent another warm front from
moving through during the day. Ridge continues to build Monday
night into Tuesday with 500 mb heights in the mid to upper 570
dms by Tuesday afternoon. The ridge axis is over Eastern
Washington Tuesday and Wednesday. The blend has put a slight
chance of rain west of Puget Sound and over the Northwest
Interior Wednesday. Can`t say the ensemble solutions are
completely dry but both the GFS and ECMWF ensembles only have
around 10 percent wet solutions for Quillayute. Look for these
slight chance pops to go away in future forecast packages. Ridge
retrograding a little Thursday with the ridge axis right over
Western Washington. Unseasonably warm days Tuesday through
Thursday. Vast majority of the ECMWF ensemble solutions for the
high in Seattle Wednesday are 60 or 61 degrees. GFS ensembles a
couple of degrees cooler. The record high in Seattle Wednesday
is 63 degrees set in 2009. All three days, Tuesday through
Thursday, highs up to 10 degrees above normal, in the mid 50s
to lower 60s. Felton

.AVIATION...
West to southwest flow aloft will continue into tonight. A cold
front will produce another round of rain and MVFR ceilings this
afternoon and evening. MVFR conditions will prevail tonight as
another warm front approaches the area. Gusty south to southeasterly
surface winds are expected...especially coast and north interior
areas...into this afternoon before easing.
KSEA...Expect ceilings to lower to MVFR this afternoon as another
round of rain moves through the terminal. MVFR conditions look to
persist tonight as well. South/southeast winds will begin to
increase after 15Z, peaking between 18-00Z with gusts up to 15-20
kt. Winds will gradually ease this evening, becoming light tonight.
&&
.MARINE...A low pressure system will continue to move
northwestward across the area, with the cold front moving across the
area waters late today. Gales over the coastal waters and the East
Strait of Juan de Fuca will continue for most of the day today until
the cold front passes through, after which winds will begin to ease.
Small Craft Advisory winds will also continue for the Northern
Inland Waters and Admiralty Inlet through this afternoon. Over the
coastal waters, winds will ease briefly tonight before increasing on
Saturday as another system well offshore begins to approach the
area. This system will then traverse the area waters on Sunday.
Broad high pressure then builds across the Pacific Northwest next
week, which will allow for offshore flow to prevail across the area,
pushing incoming weather systems off to the north.
Seas around 12 to 15 ft this morning will slowly ease tonight to
around 10-12 ft through the weekend. Weather systems passing by off
to the west will keep seas in the 8-12 ft range going into next week.
