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 Apr 1, 2:29 PM PDT, 6 hours 25 minutes earlier.

Area forecast discussion, Apr 1, 2:29 PM PDT, 6 hours 25 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
229 PM PDT Sat Apr 1 2023

.SYNOPSIS...Showers will increase in coverage and intensity
tonight through Sunday. In addition, periods of light to moderate
snowfall will impact mountain roads and passes in Del Norte and
Humboldt Counties. Otherwise, gusty north winds will develop
across the region during Monday morning. Light showers will remain
possible Tuesday through Thursday, followed by potentially warmer
and drier weather next weekend.

&&

.DISCUSSION...Cool northwesterly flow aloft was occurring over
the West Coast this afternoon, while in the low-levels, a shallow
moist layer was promoting occasional drizzle and showers in NWRN
CA, particularly across the coastal foothills. During the next 24
hours, an upper-level shortwave trough is forecast to progress
east across the NERN PAC. That feature will aid in deepening the
moist layer, and cooling temperatures aloft will also steepen
lapse rates. Showers will subsequently increase in coverage and
intensity, particularly across Del Norte and Humboldt Counties.
In addition, snow levels situated between 2000 to 2500 ft MSL will
favor light accumulations across the higher ridges and passes in
Del Norte and Humboldt Counties. Some travel impacts may occur
along portions of HWY 199, 299, and 36 due to 2-4 inches of snow
accumulation between 5 AM to 11 PM Sunday. A winter weather
advisory has been issued as a result.

The previously mentioned shortwave is forecast to exit east on
Monday, but model guidance shows post-trough showers lingering
across NRN CA. In addition, north-northwesterly winds may gust
from 20 to 30 mph during part of Monday. Otherwise, minor upper
disturbances are forecast to impact the West Coast Tuesday through
Thursday, and will aid in additional shower generation. Multi-
model guidance then signals ridge amplification next weekend into
early next week, which would favor warmer and drier weather across
much of the WRN CONUS.

.AVIATION...A weak frontal boundary is moving across the area
bringing MVFR to IFR conditions due to light rain and drizzle this
afternoon. The front is moving from northwest to southeast and
areas behind the front are already seeing CIGs lifting and MVFR to
IFR conditions. CIGS will continue to gradually improve this
afternoon before another boundary starts to move onshore dropping
conditions once again this evening and tonight as it moves in from
the northwest. This will lower CIGs and vis again in the rain
showers, likely to MVFR with periods of IFR. Clouds will start to
diminish again through the day Sunday behind this boundary. MKK

&&

.MARINE...Winds and seas have diminished as the front has moved
inland today and winds have turned west to northwest this
afternoon. The winds remain around 5 to 10 kt tonight so will
allow the small craft advisory to expire this afternoon. This will
bring some 2 to 3 foot wind driven waves with it. In addition,
tonight a northwest swell is expected to move into the area and
slowly build to around 5 to 6 feet at 12 seconds.

Sunday northwest winds are expected to gradually increase through
the day to around 15 to 20 kt by late in the afternoon. A small
craft advisory will likely be needed as these pick up again.
Monday these northwest winds and associated seas will remain
elevated before diminishing on Tuesday ahead of another system.
The northwest swell is expected to build again on Monday to around
7 to 10 feet at 11 seconds. This is expected to drop to 6 to 8
feet on Tuesday.

Mid to late in the week another system is expected to bring
moderate to strong southerly winds and an additional frontal
boundary, however there is still a lot of uncertainty in the
strength and timing of this. In addition a small northwest swell
is expected to slowly diminish through the week. MKK
