What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Seattle, WA wrote its last area forecast discussion before this small craft advisory went out at Dec 27, 2:56 PM PST, 3 minutes earlier.

Area forecast discussion, Dec 27, 2:56 PM PST, 3 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
256 PM PST Mon Dec 27 2021

.SYNOPSIS...Very cold temperatures will continue through the rest
of the week, with some modification towards the latter half of the
week. Several week systems will bring light snow to area over the
next 24-36 hours, with a more organized system set for Wed night
and Thurs. A better chance for accumulating snow is expected with
this system, possibly mixing with rain Thurs afternoon. A warmer
system may then affect the area through the weekend, with active
weather likely to persist into next week.

&&

.SHORT TERM /TONIGHT THROUGH THURSDAY/...A high amplitude upper
level pattern remains in place this afternoon across the NE
Pacific and the Western US/Canada as a strong ridge resides over
the Aleutian Islands and nearby Pacific and a deep trough resides
over the West/Rockies. Near the surface, a very cold airmass
remains in place over SW Canada and the PNW, evidenced by the
continued presence of a 1020+mb high over southern BC. The leading
edge of this cold airmass lies roughly from the Northern
Rockies/Great Plains over into northern OR and to the west of the
coastal zones of the WA/OR coasts.

Given the upper level pattern in tandem with the sfc pattern, very
cold conditions remain entrenched over the PNW/W WA. As of about
230PM, temperatures across the area are in the low to mid 20s,
with teens still present over W Whatcom Co. Under these
conditions, even despite some sunshine today, little in the way of
snow melt has occurred. Fraser outflow over Whatcom Co and the
San Juan Islands has finally let up as of earlier this morning,
although some spots up there may remain a bit breezy thru the rest
of the afternoon.

Provided the deep longwave upper level trough over the region,
water vapor imagery depicts quite nicely another shortwave trough
sliding down the BC Coast this afternoon. Sfc analysis shows the
development of a sfc wave along the arctic frontal boundary that
will follow the upper level parent trough on its way towards the
West Coast of the US this evening. As expected, the track of this
system will remain along a baroclinic boundary that separates
"warmer" Pacific air with the modified continental polar air,
keeping the bulk of the dynamics associated with this system to
our west. That being said, some moisture will still be able to
creep towards the Coast, Olympic Peninsula, and SW Interior this
evening and overnight. Based on current and projected trends, an
additional 1-2" inches of snow will be possible along the Coast,
with perhaps an additional 0.5-1.0 inch across inland lowland
areas of the Olympic Peninsula and into the SW Interior (including
cities of Olympia and Chehalis). Flurries or a few stray light
snow showers could even reach parts of Puget Sound, but no
accumulation is expected.

On Tuesday, the offshore system will move inland over central OR,
carrying the moisture with it. Therefore, snow will taper from NW
to SE through the morning tomorrow, with again little modification
of the airmass area-wide. Although temperatures will struggle to
reach the freezing mark tomorrow, they will warm a good 5-8
degrees or so from today. Interestingly tomorrow, model guidance
shows yet another shortwave trough diving south out of BC late
tomorrow afternoon and evening. Although the best lift on the
downstream side of this shortwave will push across E WA, there is
evidence of a vort lobe moving across W WA. Hi-res guidance is
more aggressive than the NBM and other medium-longer range
guidance on precipitation development. Do think with a source of
lift in the area that some precip will be generated, which will
be in the form of snow. Have introduced slight chance POPs across
much of the area to account for this, mainly east of the Olympics
and over to the Cascade crest. New snow amounts will be light if
at all, generally a new dusting to perhaps a half an inch on top
of the existing snow pack. In addition to this, a reinforcing area
of sfc high pressure across BC in the wake of this system will
help Fraser outflow develop again across W Whatcom Co and the San
Juans Tues night-Wed. A wind advisory may be issued in the next
several forecast updates.

On Wednesday, a robust shortwave trough, associated with a strong
jet streak will dampen the strong anticyclone over the Pacific and
then take a nosedive towards W WA. More plentiful moisture will be
carried with this system en route to W WA, which will begin to
spread into the area late Wednesday evening. With little recovery
in temperatures, precip will fall as a more widespread snow
through the night and into Thursday morning. The biggest forecast
issue then on Thursday will be the potential for some airmass
modification as the anticipated low track is across the Strait
and Puget Sound. Oftentimes, models are too aggressive with the
"warming" and have tried to account for this. Have kept high temps
a bit below a handful of the warmer guidance, with highs in the
mid 30s over the majority of the area (below freezing across What
Co and around 40 along the Coast). Precip will likely change to
rain by late morning/early afternoon across the SW interior and
westward to the Coast. The Puget Sound area will be messy, but
will go more with all snow or a rain/snow mix. Expect all snow
across Skagit/Whatcom/San Juan Counties. Additional snowfall
accumulations of generally 1-4" through Thursday, including the
Seattle metro.

Active weather to then continue into the long term. It's important
to keep in mind the continued cold temperatures all thru the
short-term. As high temps get closer to freezing each afternoon,
some melting of snow will occur. With low temps remaining well
below freezing each night, expect refreezing of melting snow each
night, esp on roadways.

Kovacik

.LONG TERM /FRIDAY THROUGH MONDAY/...The long term forecast period
will begin with continued ridging over the Gulf of Alaska/nearby
Pacific, with troughing downstream over the Western US, although
not quite as amplified as earlier in the week. Conditions will be
drying into Friday in the wake of Thursday's winter system, with
another dip in temperature expected. High temperatures on Friday
likely to right around freezing (a few degrees warmer at the
coast, and few degrees colder up in Whatcom and the San Juans).

As we get into the weekend, a progressive area of low pressure
will push into the Aleutian Islands, which will push the ridge
over the Gulf of Alaska towards the area. This will help change
the pattern a bit by orienting the storm track more off the
Pacific. A frontal system associated with the progressive
shortwave will quickly dart across the Gulf of Alaska thru
Saturday. The warm frontal portion of the system will push across
W WA thru the day, bringing some light precip which may start as
snow, but with temps having a better chance at modifying some,
could be another rain/snow mix later in the day. Again, will need
to be mindful of how quickly the cold air becomes replaced by
more modified Pacific air. By Sunday, the cold front will approach
the area and eventually move across, bringing more widespread
precip. Confidence is higher in temps warm enough for the return
to rain so expect a wet and messy day and snow begins to melt too.

Troughing appears to become more dominant over the far NE Pacific
near the PNW and BC Coast into Monday, keeping active weather
likely for the local area. Although temps will by no means be
warm into next week, it does appear we get back to the more
typical winter weather across the area. As is usual, the exact
placement of this trough will need to be watched closely in the
coming days. As of right now, WPC cluster solutions largely favor
a trough centered just offshore the BC coast near Haida Gwaii.

.AVIATION...Cold weather through most of this week with northwest
flow aloft. A system will slide along the coast tonight into Tuesday
morning for light snow spreading into the coastal areas and mainly
areas south and west of Kitsap County with light snow accumulations
in these areas. Some light snow showers for the interior possible,
but little to no accumulation. Mainly VFR with MVFR in some areas
tonight into Tuesday, best chance along the coast. Drier weather
later Tuesday with some light snow possible Tuesday night. Winds
will be light north to northeast through tonight and Tuesday.

KSEA...Dry weather through this evening. Slight chance for light
snow tonight, little to no accumulations expected through Tuesday.
VFR cigs into tonight with MVFR cigs possible, mainly late tonight
and Tuesday morning. Light north to northeast winds under 5 kts
tonight and Tuesday. JD

&&

.MARINE...Winds are mainly light into tonight with Small Craft
Advisory winds along the coast as a weak system moves through the
area. SCA winds possible in the interior waters on Tuesday with some
weak Fraser outflow winds. The Fraser Outflow will increase Tuesday
night into Wednesday with Gales for the northern interior areas
possible. SCA winds for the interior waters and coastal waters. A
system will move through the area Wednesday night and Thursday for
increasing winds across the area. Swells along the coast of 3 to 5
feet increasing Tuesday of 5 to 7 feet for the coastal areas. JD
