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 15, 9:50 AM PST, 5 hours 7 minutes earlier.
Area forecast discussion, Jan 15, 9:50 AM PST, 5 hours 7 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
950 AM PST Fri Jan 15 2021
.SYNOPSIS...An exiting cold front will allow for a few lingering
showers this morning, otherwise dry conditions are expected for
Western Washington today and into Saturday. The next front moves
through Saturday night with another round of precipitation. An upper
level ridge sets up over the area early next week bringing dry
conditions through Tuesday.
&&
.SHORT TERM /TODAY THROUGH SUNDAY/...The exiting cold front probably
best seen on satellite imagery...as some clearing is starting to
take place over the NW portion of the CWA. Radar continues to show
some very weak echoes, likely to be sprinkles/drizzle/mist/light
rain...or, the short version, minor precip. Dry conditions and
clearing skies still expected for the afternoon area-wide. This will
continue through most of the day Saturday as upper level ridging
traverses over into E WA. Next frontal system expected Saturday
night into Sunday morning looks to be very much akin to the front
that moved through last night/this morning...quick moving, fairly
weak with not much in the way of precip expected and likely game
over by the afternoon.
Daytime highs in the short term offer little in the way of variation
with most lowland locations reaching the upper 40s to around 50.
Inherited forecast handles all of the above well and will not be
needing any sort of morning update at this time. 18
.LONG TERM /MONDAY THROUGH THURSDAY/...From Previous Discussion...A
dry start to the work week is expected as an area of high pressure
centered off the Northern California coast extends its upper level
ridge over Western Washington. Both deterministic and ensemble
models are bit conflicted about how an upper level low will track
through British Columbia starting Tuesday afternoon. While models
are in agreement that the low will be centered to the north of
Washington, they cannot decide on how the associated fronts will
behave. Some have this front breaking apart and weakening which
would result in less precipitation, others have what would be a
pretty typical frontal system moving through the area. Either way
things precipitation will be fairly light for the area, and we
expect a dry Wednesday.
Now, for the part of the discussion that all the winter weather
lovers have been waiting for: the potential for lowland snow
towards the end of the week.
Based on the fact that models are not yet on a consensus for the
weather system on Tuesday, we cannot have high confidence in what
they are forecasting for day 7 onward. That said, both the GFS and
ECMWF as well as their corresponding ensembles have temperatures
dropping towards the end of the week. Which is a good sign if you
are wanting the more wintery precipitation. However, guidance
keeps pushing back the start to these more wintery conditions.
However, the differing models as well as the ensembles are in more
of an agreement on a positively tilted trough setting up over the
state of Washington, which would bring in that north/northeasterly
wind which is beneficial for snow in the area, but as it stands
right now daytime temperatures are still a bit too high for snow
in the lowlands. Moreover, the probability of precipitation is
below 50%. With all that said, we are still in the wait and see
pattern. Things should become a lot clearer in the coming days.

.AVIATION...Light precipitation echoes are traversing the area,
mostly through the southwest interior. A weak convergence zone is
moving across Snohomish County, with minor KPAE impacts possible.
Conditions are expected to be improving this morning from MVFR to
VFR this afternoon. A gradual decrease back to MVFR and lower is
expected later this evening as conditions are favorable for fog.
Surface winds are expected to remain light, at or below 5 knots.
KSEA...The light rain and drizzle will be minimized over the
terminal through the morning hours. VFR conditions to prevail
through the day before decreasing overnight as fog settles in across
the area. MVFR cigs likely between 07-09z. Surface winds are going
to remain light, at or below 5 knots through the day generally out
of the NNE.
Kristell
&&
.MARINE...Offshore seas rising this morning as another large swell
train reaches the coast today. Westerly swells of 14-17 feet
possible. Generally calm conditions expected otherwise through
Saturday. Small Craft Advisory winds remaining in the Strait of Juan
de Fuca this morning, for a small westerly push through to roughly
18z. Another round of advisories likely as the next system moves in
late Saturday into Sunday.
Kristell
&&
.HYDROLOGY...From Previous Discussion...Most area rivers continue to
recede at this hour with only light rainfall amounts being observed
from the current passing system. At this time, only 2 rivers remain
in flood stage - the Skokomish and Chehalis. The Skokomish is
expected to respond to this morning's rainfall and rise slightly
today before finally falling below flood stage early Saturday. The
Chehalis River near Grand Mound has crested and is expected to fall
below stage later this morning. The Chehalis River at Porter will
take longer to fall, likely not to below flood stage until early
Saturday. Refer to the latest river summary product (RVASEW) for a
list of rivers currently in flood stage.
Outside of the Skokomish, impactful rises on rivers/new river
flooding is not expected with the additional rainfall from the
current passing system. Dry conditions Saturday with another weak
front on Sunday. At this time no impacts to the rivers are expected.
Conditions look to then turn gradually colder through next week,
with lower snow levels as additional systems pass through.
