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 Jul 23, 8:55 PM PDT, 5 hours 43 minutes earlier.

Area forecast discussion, Jul 23, 8:55 PM PDT, 5 hours 43 minutes before
Area Forecast Discussion
National Weather Service Seattle WA
855 PM PDT Fri Jul 23 2021

.UPDATE...No changes were needed to the current forecast.

.PREV DISCUSSION... /issued 243 PM PDT Fri Jul 23 2021/

SYNOPSIS...An upper ridge will keep weather systems from
approaching Western Washington into next week. Varying degrees of
onshore flow will keep temperatures from rising too much above
average until after the middle of next week.

SHORT TERM /TONIGHT THROUGH MONDAY/...Still some clouds off the
north coast but otherwise skies are mostly clear. Shallow marine
stratus and some fog should develop overnight along the coast and
in the Strait of Juan de Fuca. Areas of morning clouds and patchy
fog will burn off quickly Saturday morning and most areas up and
down I-5 shouldn't see anything. Probably Whidbey Island is about
as far east as the shallow marine layer clouds and fog should push
around daybreak Saturday. Seasonably warm weather is on tap for the
weekend and into Monday with highs ranging from near 70 along the
coast to the lower 80s in the warmer areas in the interior of
Western Washington. A few of the warmest spots near the Cascades
might sneak out mid 80s for highs. 19

LONG TERM /TUESDAY THROUGH FRIDAY/...Western Washington will be
between an upper trough in the northeast Pacific and the hot
western upper ridge which will be centered roughly over Colorado
for the first half of next week. Western Washington can expect mostly
clear skies--except now and then we might see some late night
coastal marine stratus. Temperatures will be seasonably warm and
range from highs the around 70 at the coastal beaches to the lower
to mid 80s in the warmer interior through midweek. For the last few
days of the month temps will rise a bit more but will fall far short
of the craziness at the end of June, but lower 90s for highs looks
pretty likely at Seatac at month's end. 19

.AVIATION...Clear skies prevail at the TAF sites this evening, with
stratus confined to the immediate coast. Expect stratus to make a
push inland tonight, mostly into the Lower Chehalis Valley and down
the Strait into northern Puget Sound. This is likely to bring LIFR-
IFR ceilings to KHQM and KCLM, possibly KPAE. Winds light out of the
N/NE overnight, picking up to 8-12kts Saturday afternoon.

KSEA...VFR. Winds light out of the N tonight, picking up to around
10kts tomorrow afternoon.

Kovacik

MARINE...Onshore flow will continue for the next several days
with high pressure offshore and lower pressure east of the
Cascades. Small craft advisory strength west winds are likely
most nights in the Central Strait of Juan de Fuca and East
Entrance. West winds could rise to gale force in the Strait
Sunday night. Schneider
