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 May 21, 9:05 PM PDT, 5 hours 43 minutes earlier.
Area forecast discussion, May 21, 9:05 PM PDT, 5 hours 43 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
905 PM PDT Fri May 21 2021
.SYNOPSIS...Generally dry weather expected through Saturday with an
exception along the Cascades where afternoon and evening showers may
be possible. An upper level low will shift north importing moisture
and bringing a chance for rain showers for portions of Western
Washington Sunday and into next week.
&&
.SHORT TERM /TONIGHT THROUGH MONDAY/...Satellite imagery and
doppler radar show what little shower activity there was in the
Central and Southern Cascades has come to an end this evening.
Still some cloud over over the Cascades as well as west of Puget
Sound with a dissipating front off the coast. The stratus never
did go away along the coastline today. Temperatures at 8 pm/03z
were in the 50s and lower 60s.
Little change in the pattern overnight into Saturday with the
front offshore continuing to dissipate and upper level low
southeast of the area remaining close enough for the chance of
late day showers in the Central and Southern Cascades. With the
light onshore flow continuing at the lower levels the stratus
along the coast will remain through most of the day Saturday.
Areas of low clouds will again form over the interior early
Saturday morning but by midday there will be plenty of sunshine
except along the coast. Highs will be a little warmer Saturday in
the interior with 60s and lower 70s. The coast will stay in the
50s.
Upper level low finally moving east Sunday with weak upper level
ridge building into the area. Another upper level low will
approach the area from the west Monday bringing a chance of
showers back to the forecast. Current forecast has the trends
covered. No update this evening. Felton
.LONG TERM /TUESDAY THROUGH FRIDAY/...Previous discussion follows. Next system of consequence
will be an upper level trough pushing through the area Monday
bringing likely PoPs to much of W WA throughout the day. Additional
troughs are expected to pass through Tuesday keeping showers in the
forecast as the parent upper level low hangs out over northern B.C.
A passing minor upper level ridge will dry things out for Tuesday
night and into Wednesday before another system approaches the area
bringing a return to the chance for rain once again by Thursday.
High temps in the extended will start out right at seasonal normals
for Monday with interior lowland highs in the lower 60s. Drier
conditions will bump temps Tuesday and Wednesday into the mid 60s
before the Thursday system knocks them back down a couple degrees
back into the lower 60s. High Temps along the coast will remain in
the mid to upper 50s throughout the period. 18
&&
.AVIATION...An upper ridge will build over the offshore WA waters
as an upper low continues to move across the Southwest U.S. This
will continue to promote north to northeast flow aloft over
Western Washington through the TAF period. At the surface, onshore
flow will continue with high pressure offshore and lower pressure
east of the Cascades. Not much activity on radar across the
region tonight, with satellite showing clouds already pushing in
along the coast this evening-and terminals like KHQM reporting
MVFR cigs. Generally VFR cigs are expected to persist for most
Sound terminals tonight, but another round of stratus could bring
conditions back to IFR or LIFR in places for a few hours on
Saturday morning (with clouds likely arriving between 12-15Z).
Mostly sunny skies are expected by Saturday afternoon.
KSEA...VFR conditions with SW surface winds generally between 5-8
knots, becoming light during the overnight period. Another round
of low clouds may impact the terminal early Saturday morning which
could bring the cigs down between MVFR and IFR for a few hours.
After burning off, a mostly sunny day is expected on Saturday.
Kristell/Borth
&&
.MARINE...Onshore flow will continue through the weekend with high
pressure offshore and lower pressure inland. Gale force westerlies
down the Strait of Juan de Fuca are possible tonight before easing
to Small Craft Advisory strength winds early Saturday morning.
Saturday evening looks like a better chance for more solid gales
in the Strait, and thus a Gale Watch remains in effect for
Saturday afternoon and evening.
A weak frontal system will move through the area on Monday,
temporarily easing the onshore flow and turning winds more
southerly. Moderate onshore flow will then return on Tuesday
behind the front, before the next possible system arrives later in
the week.
Seas offshore will remain benign, generally between 3-5 feet
through Saturday, before increasing to 5-7 feet on Sunday.

start of the next rainy season; it will only be updated as needed.
