What forecasters said that day
The local office's own words before this gale watch 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 gale watch went out at Apr 28, 1:36 AM PDT, 12 hours 41 minutes earlier.
Area forecast discussion, Apr 28, 1:36 AM PDT, 12 hours 41 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
136 AM PDT Tue Apr 28 2026
.SYNOPSIS...A slight chance for interior thunderstorms Tuesday
afternoon with probabilities diminishing before sunset. High
pressure continues to build. Drier weather returns at the end of the
week.
&&
.DISCUSSION...As an additional low pressure ejects southward of the
CWA, we can expect another round of daytime convection Tuesday for
the interior. The top sector of the low will be pulling moisture
with an easterly flow at the mid to lower levels. This perturbation
will be slightly enhanced by bulk shear which could give a bit of
slant, enabling some thunderstorm development. CAPE values are modest
and most of the areas of risk are Trinity county as well as eastern
Mendocino and Lake counties near the mountainous eastern flanks and
boarders.
A shallow marine layer along the coast is expected mostly each
night/early morning through the end of the week. Otherwise, a
mostly dry set up for the weekend although there are decent
signals for CAPE (~500j/kg), Saturday and Sunday. High pressure
will continue to fill in for the next few days bringing warmer
temperatures and likely driving up the CAPE values due to the
buoyancy of the air parcels. A lack of moisture and CIN will keep
a lid on things. Model soundings do show inverted V's but without
supercooled droplets or higher dewpoints there will not be enough
moisture to pose any sustained or high confidence threats. /EYS
&&
.AVIATION...Mostly MVFR/VFR expected as the low ejects south.
Terminals will have short periods of MVFR ceilings overnight into
Tuesday morning. Expect a winds to shift to an easterly bearing
overnight as the northernmost edge of the low pulls a CCW flow
back into the area terminals, primarily on the coast. Model guidance
indicates moisture will once again increase overnight into Tuesday
morning, allowing potentially MVFR ceilings to redevelop,
particularly north of Cape Mendocino along the Humboldt and Del
Norte coasts. Surface condensation pressure deficits are not very
low, likely indicating a stratus deck rather than surface fog.
&&
.MARINE...The coastal environment will be dominated by lowering pressure
across the interior west and high pressure building over the eastern
Pacific. This will allow the pressure gradient to tighten over the
next several days and north winds to ramp-up to near gale or gale on
Friday into Saturday. Steep seas will build in response to the winds
with seas exceeding 10 feet at around 8 to 9 seconds in the outer
water zones. Local model guidance has been trying to push for larger
waves approaching 15 feet in the outer waters on Friday. Either way,
the seas will be steep and either hazardous seas warnings or gale
warnings will likely be needed late in the week into the first part
of the weekend for at least the outer water zones. /RPA
&&
.EKA WATCHES/WARNINGS/ADVISORIES...

None.
