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 Jul 24, 3:38 AM PDT, 10 hours 46 minutes earlier.

Area forecast discussion, Jul 24, 3:38 AM PDT, 10 hours 46 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
338 AM PDT Mon Jul 24 2023

.SYNOPSIS...Temperatures will continue to slightly cool today with
quiet, seasonable weather continuing through the week.

&&

.DISCUSSION...A deep trough aloft will continue to push high
pressure east, resulting in gradual cooling today. Near average
highs will return today with interior valleys in the low 90s. NBM
shows less than a 5% chance of any highs above 100 through the week.
Heat Risk will generally drop to minor levels. For the coast, highs
will remain in the mid 60s. As the interior cools, the marine
inversion will slowly lift, allowing for less marine fog and higher
stratus. A generally weak inversion alongside diminished onshore
wind will most likely allow for robust afternoon clearing to
continue despite a deeper cloud deck. NBM is even hinting that
particularly weak onshore wind today and tomorrow (partially thanks
to a very weak center of low pressure zooming up the coast) may even
allow for some near coastal temperatures just below 70 assuming that
the normal sea breeze can be sufficiently delayed.

Alongside cooler air, the trough will bring instability aloft
midweek. Generally dry air, however, continues to stream in from
unusually cool water off the Southern California coast. There
remains no monsoon moisture in sight. Without moisture, there is
little to no risk (<5%) of any thunderstorms this week. At most,
increased instability will just help drive slightly gustier
afternoon winds. Conditions will remain very dry at the surface with
minimum RH each afternoon in the upper teens.

Thankfully, more westerly flow aloft has started to push smoke from
the Flat fire east of the area. Some instability aloft will only
accelerate the clearing of any residual smoke. Seasonable weather
will continue through the week with no sign of above normal
temperatures in model ensembles until at least next week. /JHW

&&

.AVIATION...Low clouds and fog have been covering coastal terminals
again this morning. Conditions overnight ranged from 1/4SM FG VV002
at KCEC to P6SM SKC at KACV. The marine layer has deepened slightly
with clouds extending into the coastal river valleys overnight.
Expect low clouds and fog to rapidly burn off again by mid morning,
however patches of LIFR or IFR in fog/low clouds will probably
linger near the land-ocean interface through the afternoon hours.
Conditions at or nearby coastal terminals are forecast to
deteriorate to IFR again this evening and overnight. For KUKI, clear
skies are expected through the forecast period (12Z Mon-12Z Tue). A
few NW wind gusts up to 20 kt are expected again this afternoon,
after about 20Z.

&&

.MARINE...A weak front will continue to disrupt the pressure
gradient across the area today through tonight. Generally light
winds (10 kt or less) and low seas (5 ft or less) are expected as a
result. Locally gusty north winds up to 30 kt are still expected to
occur downwind of Punta Gorda through this evening. The front will
lift out to the NE and dissipate on Tuesday with high pressure
gradually rebuilding offshore through the day on Tuesday. Northerly
winds are forecast to increase in response to the tighter pressure
gradient by afternoon. Once again, the strongest winds are forecast
to occur in the lee of Cape Mendocino, with localized strong gusts
up to 40kt expected by Tue evening. A second expansion fan will also
develop downwind of Cape Blanco with localized gale force gust
(35kt) extending southward into the northern outer waters Tue night.
In both areas, the areal coverage of gale force gusts does not
appear to be sufficient at this time to warrant a watch. Steep waves
are forecast to increase Tue night in response to northerly wind
surge, with heights up to 8-9 ft at 7-8 seconds by Wed afternoon and
evening. Another round of advisories for small craft are anticipated
Tue into Wed. Moderate (15-25kt) to locally strong (35-40kt) winds
and elevated seas (8 ft or more) will probably persist downwind of
Cape Mendocino on Thu. North of Cape Mendocino winds and seas will
probably not be as strong.
