What forecasters said that day

The local office's own words before this gale warning 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 warning went out at Apr 4, 2:45 PM PDT, 12 hours 46 minutes earlier.

Area forecast discussion, Apr 4, 2:45 PM PDT, 12 hours 46 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
245 PM PDT Tue Apr 4 2023

.SYNOPSIS...Periods of showers will impact Northwest California
through the remainder of the week, and likely into early portions
of next week. In addition, temperatures will remain cool, with
frost and freezing temperatures expected Wednesday morning.

&&

.DISCUSSION...Clouds and showers are forecast to gradually recede
from much of NWRN CA late tonight. As that occurs, robust
radiational cooling is expected across much of the interior
resulting in hard freeze conditions for NRN Lake and NERN
Mendocino Counties. Elsewhere across the remainder of Mendocino
north into interior Humboldt County, freezing temperatures from
29 to 32F are forecast to occur, with slightly warmer conditions
expected around Humboldt Bay promoting frost. Otherwise, mid and
high clouds will increase across the region during Wednesday, with
a shield of stratiform rainfall advancing east across the coast
Wednesday evening into Thursday. A more robust upper trough is
then forecast to deepen over the NERN PAC during late week, with
multi-model guidance showing several rounds of precipitation
occurring this weekend into early next week. That precipitation
will initially occur in the midst of a warm deep-layer airmass
resulting in limited snow impacts. That will be followed by
potentially cooler midlevel temperatures overspreading the region
early next week and aiding in an increasing chance of high
elevation snowfall.

Garner

&&

.AVIATION...Mostly VFR conditions are expected during the TAF
period. Overall, a ridging pattern will persist with a weak
disturbance moving through this afternoon which will bring low mid
cloud, potentially dropping ceilings to MVFR along the Del Norte
Coast. Gusty NW winds in Mendocino and Lake counties this
afternoon should weaken this evening, and lingering mid cloud
along with an approaching weak shortwave should inhibit fog
formation.

&&

.MARINE...Northwest breezes and seas continue to diminish today
from north to south as ridging builds aloft. A northwest swell is
expected to drop off today. A a strong front approaches Wednesday
night, possibly bringing sustained Gale Force southerlies to the
northern waters by early Thursday morning. A gale watch for the
northern waters remains in place. Besides that, a solid WNW swell
may fill in this weekend, peaking somewhere in the mid teens
around 15 seconds.
