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 Jun 29, 3:07 PM PDT, 11 hours 19 minutes earlier.

Area forecast discussion, Jun 29, 3:07 PM PDT, 11 hours 19 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
307 PM PDT Mon Jun 29 2020

.SYNOPSIS...Pacific high pressure will remain in control of our
weather through this week, with no precipitation in sight. Coastal
clouds and fog will be relatively localized, with mostly sunny
skies otherwise. Northwest breezes will be present each afternoon
with seasonable temperatures at the coast and inland.

&&

.DISCUSSION...Northwest California is almost completely devoid of
clouds this afternoon, with a dry and relatively stable airmass in
place as a substantial upper-level trough continues to track
farther away to our east. High pressure at the surface and aloft
will continue to build into our area tonight and Tuesday, but
troughs will continue to drop southeastward from British Columbia
and the Gulf of Alaska through next weekend, which will keep the
interior from heating up too much. Northerly breezes are still
very noticeable today, with some gusts into the 20 to 30 mph range
along the exposed portions of the coast, near-coastal ridgetops,
and ridgetops in southeast Lake County. Along the coast though,
these winds are not nearly as strong as we saw yesterday, where
some spots gusted over 40 mph. The weather pattern will continue
to favor breezy conditions for the coast and adjacent mountain
ridges through mid-week. These breezes will not be anything
particularly notable, but they are more typical of Spring rather
than early July. This, along with a relatively weaker inversion
for this time of year, will tend to limit coastal stratus in
coverage and duration, allowing for a somewhat unusual amount of
sunshine for early July. There may be a reinforcing onshore push
from the northwest coming in on Tuesday that could help increase
overnight and morning clouds around the lower Eel River Valley up
to Trinidad, especially Wednesday morning. Areas farther north
toward Crescent City and to the south along the Mendocino coast
look sunnier. Across the interior valleys, high temps warmed up
into the 80s this afternoon, and that will generally be the rule
throughout this week, which is very close to seasonal averages for
early July. We still see no sign of any precipitation through next
weekend, with deeper moisture and instability to spark any showers
staying well to our north, toward northern Oregon and Washington.
/AAD

&&

.AVIATION...Visible satellite imagery shows clear skies along the
coast and interior. VFR conditions are prevailing for KACV and
KUKI. Marginal MVFR conditions are lingering at KCEC due to hazy
skies. Winds continue to be the primary aviation concern with
occasional gusts from 25 to 30 kt at KCEC and KACV lingering into
the early evening hours. Otherwise, diminishing winds are expected
later this evening as the boundary layer stabilizes. HREF model
shows the development of marine layer and patches of stratus
clouds along the coast overnight, especially in the vicinity of
Humboldt Bay. Elsewhere, VFR conditions will prevail across the
interior. /ZVS

&&

.MARINE...The persisting pressure gradient between the offshore
surface high and thermal troughing over coastal California has
shifted. This has resulted in sub-gale force winds in southern
outer waters, south of cape mendocino. A hazardous seas warning is
in place to represent the elevated seas in PZZ475 and SC.Y in all
other zones of our CWA. Small craft conditions will persist
across all coastal waters during Tuesday, followed by a period of
possible gale force conditions on Wednesday. Thereafter, a
slackening surface pressure gradient is forecast to occur Friday
and Saturday, which may yield sub-advisory winds and seas. /EYS

&&

.FIRE WEATHER...Wind gusts peaked in the 35 to 45 mph range across
the most exposed ridgetop sights around the periphery of
southeastern Lake County early this morning, with poor overnight
recoveries in the 35 to 45 percent range. Winds are steadily
subsiding, but will remain in the 8 to 15 mph range across
exposed locales with elevations above 1500 feet in SE Fire Weather
Zone 264, with some local ridgetop gusts 20 to 25 mph this
afternoon, before winds diminish this evening. RH is in the 15 to
25 percent range as well, and recoveries in the Red Flag Warning
area will probably only be in the 40 to 55 percent range tonight.
However, with winds calming down, we should be able to let the
warning go at 6 PM. Beyond that, it will remain dry through next
weekend, with continued modest recoveries at times over the
ridges of our eastern and southeastern fire weather zones, but
winds look light enough so that we do not expect headlines at this
time.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...Red Flag Warning until 6 PM PDT this evening for CAZ264.

NORTHWEST CALIFORNIA COASTAL WATERS...Small Craft Advisory until
     6 PM PDT Tuesday for PZZ450-455-470.
