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 Sep 10, 4:03 AM PDT, 10 hours 39 minutes earlier.

Area forecast discussion, Sep 10, 4:03 AM PDT, 10 hours 39 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
403 AM PDT Sun Sep 10 2023

.SYNOPSIS...Mostly dry weather is expected for the next seven
days. Some patchy coastal drizzle is forecast Monday morning.
Temperatures are forecast to remain near normal today through
early next week and then warm above normal mid to late next week.

&&

.DISCUSSION...Coastal low clouds returned during the night and
have pushed into many of the North Coast river valleys. Top of
the marine layer appeared to be around 2000 to 2500 feet. The
low-level inversion has remained weak, so expect stratus to
dissipate by midday with ground heating and mixing. A front will
approach tonight and disrupt the onshore flow. Model guidance
has this weak front pushing onshore the North Coast early Monday
morning. Measurable drizzle on the order of a hundredth or two
will be possible (10-20%) for coastal areas. Another weak front
will follow Monday night and may generate more drizzle and a
deeper push of marine air into the river valleys by Tuesday
morning. Chance for 0.01 of an inch for areas away from the coast
is very minimal, no more than 10%. Northerly winds will increase
offshore after the passage of a mid-level shortwave trough later
on Tue into Wed. An upper ridge is then forecast to amplify around
Thu bringing above normal temperatures to much of the northern
interior. Thermal trough is forecast to develop along the North
Coast on Thu and will promote an offshore flow, less stratus and
some warming for the North Coast. Uncertainty with the duration
of the warm up increases going into next weekend. Global models
indicate a potential for thunderstorms as an upper low undercuts
the ridge with above normal PWATS spreading over the area in SE
flow aloft next weekend. This will need to be watched closely.

&&

.AVIATION...CIGS have stabilized at the IFR level early this morning
(10Z) with P6SM VSBY. Nighttime satellite imagery reveals significant
weakness in stratus continuity. ACV carried CLR sky conditions
under a small, highly localized hole in the ceiling, mainly
created by light ENE winds. The probability for LIFR CIGS at CEC
will reach up to 51% from 13Z to 16Z. A tempo has been included to
cover this. Scattering and periods of VFR are anticipated this
afternoon, with the best chances at ACV. Influence from a weak
front and favorable westerly winds may hold more cloud cover
around CEC today, but levels should vary from MVFR to IFR (55%).
The approaching weak front will encourage deepening in the marine
layer towards the latter end of this 12Z TAF period. Some light
drizzle may accompany the front. This setup will yield higher
chances for MVFR to IFR cloud levels as the stratus fills back in
tonight. UKI is still forecast to remain VFR, though there will be
increasing chances for stratus to carry over the higher terrain
into the valley from the west with the deepening of the marine
layer.

&&

.MARINE...A small, long period southerly swell of 2 to 4 feet
from Hurricane Jova will fade into next week. Winds today will be
very light in the northern waters, and will continue to be
accelerated along an isolated area south of the cape of up to 25
kt this afternoon and evening. Seas will steepen up to 6 ft in
this wind prone area. The northerlies will strengthen and expand
through the outer waters on Monday, with better coverage of gale
strength gusts around the cape. A thermal trough will strengthen
Tuesday through Wednesday. The northerlies will be strongest
through this period, when areas of gale strength gusts will
periodically develop in the southern waters, and to a lesser
extent a small portion of the northern outer zone.

&&

.FIRE WEATHER...Northwesterlies will increase peak in the southern
half of the forecast area today. Gusty ridgetop winds will be
likely into tonight from southern Humboldt county through
Mendocino and Lake counties. Locally enhanced fire weather
concerns will develop as ridgelines experience poorer overnight
recoveries (particularly across Lake and NE Mendocino counties).
Wind gusts to around 25 mph will be possible with overnight
relative humidity recoveries in the 40s and 50s. Will continue the
headlines in the Fire Weather Forecast. A front will move across
the area on Tuesday, gusty westerly and northwesterly breezes
are forecast to occur again. Humidities will generally remain
above 30% where gusts approach or exceed 25 mph, though a portions
of interior Mendocino, Trinity and Lake Counties will flirt with
criteria for a few hours. A thermal trough will build toward the
end of the week bringing hotter temperatures and drier humidities
for Del Norte and Humboldt counties, mainly in the interior.
Gusty easterly and northeasterly ridge level breezes and poor
nighttime recoveries are also anticipated.
