What forecasters said that day

The local office's own words before this gale warning 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 gale warning went out at May 29, 2:45 AM PDT, 3 minutes earlier.

Area forecast discussion, May 29, 2:45 AM PDT, 3 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
245 AM PDT Mon May 29 2023

.SYNOPSIS...Main focus for this discussion is the zonal flow to
start the week with cool temperatures and marine pushes with the
onshore flow. Looking for the potential of drizzle midweek along
the coast with a long-wave trough push from the Pacific and the
switch to offshore flow this weekend. Potential for above average
temperatures exists starting next weekend with some precipitation
chances mainly along the Cascade Ridge.

&&

.SHORT TERM /TODAY THROUGH WEDNESDAY/...Zonal pattern remains in
the upper levels to start the short term forecast period. An
upper-level low stays down in California and a trough to the east
will progress giving way to a long-wave trough coming from the
Pacific by Wednesday. At 300 mb the jet core will be over WA by
Tuesday night/Wednesday which will support rising motion in the
right entrance region. There's good consistency with this in
between the ECMWF GFS and NAM with the aggressiveness of this
jet.

Dynamically there is some weak vorticity advection at 500 mb and
700 mb Tuesday night/Wednesday to support some lift. However
moisture aloft remains relatively dry in the model guidance with
no support at the aforementioned levels. Down near the surface a
weak surface trough sets up along the Cascade Ridge with onshore
push continuing through the short term period. There is sufficient
moisture near the surface with RH values approaching 80-90 percent
with the marine stratiform pushes coming on the coast.

Given the dynamical environment and the onshore pushes will keep
temps cooler with the expected morning marine stratus to push
inland during the next few mornings. As temperatures climb do
expect most areas to clear out for the afternoon and evening for
all mornings. The weak synoptic environment will only allow for
drizzle in the morning especially near the coast with the
moisture near the surface and the drier air higher up. Winds
remain light out of the west of 5 to 10 mph with the exception of
the Strait of Juan De Fuca with winds 20 to 30 kts.

HPR/Kovacik

.LONG TERM /THURSDAY THROUGH SUNDAY/...The upper level pattern at
the start of the long term forecast period will feature broad
troughing extending from the Aleutian Islands into the PNW. A
shortwave trough embedded within this flow will skirt across W WA
through the day on Thursday. Weak dynamics and meager moisture
will prevent much in the way of sensible weather impacts across
the area, however an isolated shower or thunderstorm cannot be
completely ruled out over the North Cascades. Continued onshore
flow in the low levels will make for similar temperatures as what
was experienced for much of the short term period.

By Friday, the large scale upper level pattern will amplify, with
strengthening high pressure over much of Canada and the northern
tier of the US and a deepening trough over the far NE Pacific. As
the ridge strengthens over Canada, its influence will build
westward towards the PNW. Current ensemble solutions favor more of
a high pressure influence over W WA vs Pacific troughing,
however, continued onshore flow will help keep temperatures in
check, allowing them warm back only into the low to mid 70s.

Through the weekend, ensemble solutions favor increasing high
pressure influence aloft, making for a warming trend. Some
uncertainty remains in the degree of warming, but confidence is
currently high in a return to temperatures in the upper 70s to
near 80. There still remains some concern for a period of above-
normal temperatures at the very end of the forecast period and
just beyond, along with the potential for the development of weak
offshore flow.

.AVIATION...An upper level trough in the Gulf of Alaska will bring
zonal flow aloft over W WA for much of the day before gradually
turning more southwesterly as this feature starts to sag southward.
Surface flow remains onshore with generally stable conditions present.

VFR conditions remain in place over much of the interior while
marine stratus have spawned MVFR to IFR conditions as far east as
Shelton. Main forecast concern this morning will be how far eastward
that marine stratus gets. Terminals more prone to lower cigs such as
OLM, CLM and PWT should see these MVFR to IFR conditions after 12Z
this morning as models remain consistent on that. Some question
remains regarding whether or not terminals east of the Sound will
see much impact. as of 09Z this morning, cigs at PAE have already
dipped down to IFR, so will likely be inclined to leave any TAF with
MVFR to IFR cigs unchanged...as the prospect of these conditions has
already started to emerge. Wind speeds less than 5 kts over the area
throughout the morning hours before picking up slightly after 18Z
ranging generally 4-8 kts.

KSEA...VFR conditions at present but could see cigs lower after 12Z
as discussed above. IFR conditions likely becoming present over the
terminal between 12-14Z and lingering into the early afternoon
/approx 21Z/ before lifting. VFR conditions will resume afterward.
Light and variable winds this early morning before becoming more
southwesterly, with speeds generally between 4-8 kts by this
afternoon. 18

&&

.MARINE...High pressure will remain situated over the waters the
next several days, helping to maintain breezy northwesterly winds
over the outer coastal waters at times and diurnal westerly pushes
down the Strait of Juan de Fuca. Guidance remains consisted with a
staunch push this afternoon and evening and as such have upgraded
Gale Watch for the Central and East Strait to a Gale Warning.
Additionally, conditions look right for SCA conditions to develop
in the adjacent waters of the Northern Inland Waters and Admiralty
Inlet. In the meantime, northwesterlies also look to meet SCA
criteria over the coastal waters and Western Strait, meriting
additional headlines there.

Current seas ranging 3-5 ft will build during the day, getting to 5-
7 ft this afternoon and 7-9 ft tonight before peaking at 9-11 ft
Tuesday morning in the outer coastal waters. With seas dominated by
short period fresh swell, expect quite choppy conditions to continue
over the next few days. 18

.HYDROLOGY...The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed.
