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 Eureka, CA wrote its last area forecast discussion before this small craft advisory went out at Aug 26, 2:35 PM PDT, 12 hours 24 minutes earlier.

Area forecast discussion, Aug 26, 2:35 PM PDT, 12 hours 24 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
235 PM PDT Sat Aug 26 2023

.SYNOPSIS...Temperatures will be near to slightly below normal
across Northwest California during much of the next seven days. In
addition, breezy northwest winds are forecast to occur next week,
and cool showery conditions may spread across the region late next
week.

&&

.DISCUSSION...An upper low was positioned offshore from OR this
afternoon. Dry subsident southwesterly flow aloft was occurring
along the south-southeast periphery of the low over NRN CA. Dry
weather and seasonable temperatures were subsequently observed
across the EKA CWA. Going into early next week, the upper low is
forecast to open up into a trough and eject east across WA/OR
during Tuesday. A tight post-trough surface pressure gradient
combined with brisk north-northwesterly gradient flow in the
925-850 mb layer will favor winds gusting to 30 mph across exposed
ridges, coastal headlands, and terrain gaps from roughly Tuesday
through mid to late week. In addition, a second upper trough is
forecast to dig south along the coast of NWRN CA during next
Friday and Saturday. Increasing ascent and deep layer moistening
occurring within the downstream portion of the trough combined
with cold air aloft and resultant steep lapse rates will support
shower and possible thunderstorm development over NWRN CA during
the extended range forecast period.

&&

.AVIATION...Widespread stratus remains entrenched along the coast
this afternoon. Smoke from nearby wildfires continues to impact
CEC, and somewhat at ACV. Ceilings are lifting the IFR/MVFR
levels. Overnight, ceilings will trend back down to IFR/LIFR
level. By the early morning hours, expect more solid LIFR ceilings
and visibility, with a chance for TEMPO FG. Smoke will continue
to impact CEC, especially overnight through the morning hours.
Ceilings will begin to lift towards the end of the 18Z TAF period.

&&

.MARINE...Light winds persist today with seas less than 5 feet in
all zones. The NE Pacific upper low parked offshore, responsible
for this relative tranquility will begin nudging back NW Sunday.
As weak high pressure fills in, the northerlies in the southern
zones around the cape will slowly trend upward and expand in
coverage beginning Sunday afternoon. The low will kick eastward
Tuesday, when northerlies will further strengthen and begin
expanding northward to include the northern zones. Seas remain
primarily locally generated, tied to the nearshore
northerlies...although a small mix of NW and SW swells move
through the weekend and next week.

&&

.FIRE WEATHER...A series of upper disturbances moving across the
region next week will aid in north-northwest winds gusting to 30
mph across exposed ridges and through terrain gaps from roughly
Tuesday through mid to late next week. Temperatures will not be
particularly warm during that time period, and relative humidity
values will not be substantially low, but locally elevated fire
weather conditions will be possible due to the gusty winds. In
addition, multi-model guidance is beginning to support a cool
showery weather regime over NWRN CA late next week, which could
aid in mitigating ongoing fire activity.
