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 Jan 14, 2:36 AM PST, 24 minutes earlier.

Area forecast discussion, Jan 14, 2:36 AM PST, 24 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
236 AM PST Thu Jan 14 2021

.SYNOPSIS...Your Thursday is going to start off dry and stay that
way all the way through the evening. A weak cold front is expected
to move through the area later in the day and through the night,
but is expected to have exited the area come morning. A ridge
behind the front will bring us a dry start to the weekend.
However, Saturday night will be the start to a series of a weak
frontal systems moving through the area that is expected to
continue through most of next week.

&&

.SHORT TERM /TODAY THROUGH SATURDAY/...We have some mid level
clouds moving into the area early this Thursday morning. As these
clouds move in, the chance of fog decreases. Areas near Olympia
southward had fog already forming before the aforementioned clouds
moved in, resulting in some somewhat stubborn patchy areas of fog
that will likely not mix out until after sunrise. As an upper
level ridge moves through the area today, we should see that
elusive sunshine again today. That said, clouds ahead of a cold
front will be moving in this afternoon. As the front moves through
expect some light rain showers overnight. Rain accumulations in
the lowlands are expected to be less than a quarter of an inch,
and up to half an inch in some isolated locations in the Olympic
and Cascade Mountains. Snow levels will be rising during this
time to over 5000 feet.
Once the rain moves through the area early Friday morning and the
trailing showers scatter out we expect a dry Friday and Saturday!
High temperatures throughout the area will be around 50 for the
lowlands and just above freezing for the mountains. As for chances
for sun, the best chances will be Friday and Saturday morning.
Clouds ahead of a front will move over the area starting in the
afternoon, with precipitation beginning later Saturday.

Butwin

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...As the front that began
moving into the area Saturday makes its way to Western Washington,
expect a wetter start to your Sunday. Models are in agreement that
this will bring mostly light rain showers to the area and some
snow in the mountains. As of this writing no models are suggesting
for any major impacts from this event.
For the rest of the long term expect a series of weak disturbances
to move through the area roughly every other day. For As we near
the end of the long term forecast range we see deterministic
models suggesting the set up for some more wintery conditions,
ensemble guidance is conflicted on this set up. We will be
keeping a close eye on things to see how they evolve.

&&

.AVIATION...Mid to upper level clouds will continue to push across the region
this morning. This will prevent fog from developing across most
terminals this morning, with KOLM being the only terminal seeing
vsby reductions at this hour. VFR conditions will persist through
the period under SCT to BKN CIGS AOA 15K ft. Prevailing wind
generally out of the northeast AOB 10kts.

KSEA...Mid to upper level clouds continue to push across the region at this
hour. This will prevent fog from developing at the terminal this
morning. VFR conditions will persist through the period as a result,
with SCT to BKN CIGs AOA 15K ft. Prevailing winds out of the
northeast 4 to 7 kts, becoming southeasterly this evening.

Pullin

&&

.MARINE...Offshore seas will continue to decrease this morning with westerly
swells falling to 6 to 9 feet by this afternoon. An approaching
system will yield another large swell train reaching the coast on
Friday, with westerly swells increasing to 14 to 17 feet. Following
another lull this weekend, another increase in seas will be possible
early next week.

Winds will increase ahead of the aforementioned approaching system
this afternoon. Advisory level winds can be expected offshore,
spreading into the inland waters this evening and tonight. Following
a break Friday and Saturday, winds will be on the rise again Sunday
into next week.

Pullin

&&

.HYDROLOGY...Significant rainfall is not expected across the region through early
next week. With the exception of the Chehalis River which is
cresting at this time, the remaining rivers in flood have begun
receding and are expected to fall below flood stage later today.
Refer to the latest river summary product (RVASEW) for a list of
rivers currently in flood stage.

Given the recent wet conditions, the landslide threat will continue
to remain elevated through today. The next frontal system will move
across the area Thursday night into Friday, bringing another quick
round of rainfall. Additional river flooding/widespread rises are
not expected and rainfall rates will likely not be heavy enough to
trigger additional landslides.
