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 Feb 20, 4:43 AM PST, 3 hours 15 minutes earlier.

Area forecast discussion, Feb 20, 4:43 AM PST, 3 hours 15 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
443 AM PST Mon Feb 20 2023

.SYNOPSIS...A North Pacific High will keep skies clear and
temperatures mild through tomorrow. By very early Tuesday morning, a
low pressure system with colder air will bring lower temperatures
throughout the region, low elevation snow, heavy snow above 1000 ft,
potential for convective storms producing small hail at the coast,
and rain. The low pressure system will impact the region through the
end of the week. Very cold low temperatures are expected Friday and
Saturday morning.

&&

.DISCUSSION...Currently a high pressure system situated in the
Northeast Pacific is impacting Northwest California and will
continue into tomorrow. As a result, clear skies and mild
temperatures are expected to dominate. High temperatures in the
interior portions of the region are forecast to be in the mid to
high 60s this afternoon. Interior Southern Mendocino County and Lake
County could see highs of up to 70. Periods of fog are also expected
into this morning in interior valleys and around Humboldt Bay. By
Tuesday, an abrupt pattern shift is expected to occur.

Ensemble and deterministic models indicate that a low pressure
system from the north of our region will move down the West Coast
and impact Northwestern California through very early Tuesday and
into the latter portion of this week. Cold Arctic air will advect
into our region as the system moves south. The EFI indicates the
potential for lower than average temperatures for the whole region
Tuesday and into the end of the work week. By mid to late next week,
low temperatures have the potential to reach below freezing to even
the mid 20s at the coast, while interior temperatures could be in
the low 20s to high 10s. Also, gusty northwesterly winds are
forecast to occur by mid morning Tuesday behind the cold front
associated with the low pressure system. Confidence for wind
advisory conditions is high for higher elevation areas Tuesday
afternoon and into the night. Gusty conditions are expected
throughout the region with this frontal passage.

Other threats this system imposes are rain and a high probability of
low elevation snow. Higher amounts of precipitation are anticipated
to be concentrated mostly in Del Norte County and Humboldt County
north of Cape Mendocino, while lower amounts are expected for most
of Trinity County and Mendocino and Lake counties. Increasing
instability and cold low-level temperatures will also bring the
threat of small hail. Highway passes will most likely be impacted by
heavy snow in higher elevations and more likely small hail along the
coast. Snow levels are expected to drop quickly behind the cold
front with levels initially ranging from 2000-4000 ft MSL Tuesday
afternoon. Snow levels are then expected to fall to around 1000 ft
MSL by Wednesday morning, before falling even further to below 500
ft MSL early Thursday morning. As of now, NBM indicates between a
60% to 80% chance of at least a dusting of snow along the coast
north of Cape Mendocino. Confidence is growing that some snow
showers may occur at the coast north of Cape Mendocino by Thursday
morning. However, models and ensembles need to be closely monitored
in the coming days to determine any changes to the current snow
forecast for the coast.

Otherwise, showery precipitation is forecast to continue into early
Friday morning, with the potential for additional snow accumulation
as well as small hail. Afterwards, a high pressure system is
forecast to approach the region and aid in shower dissipation.
However, as mentioned previously, clearing skies and the lingering
cold air mass will favor very cold morning temperatures across
interior valleys and the coast. Another low pressure system may
impact the area by late next weekend. /JLW

&&

.AVIATION...This morning offshore flow and high pressure is mainly
bringing VFR conditions to NW CA. Some low clouds are bring MVFR to
IFR conditions from the Eel River Delta up to Trinidad including
KACV. There is some offshore flow, but so far it hasn't been enough
to clear these clouds out. Expect they will clear by mid morning if
not earlier, but confidence is low on this as the models aren't
picking up on them. Winds will be breezy this afternoon, but only
around 10 to 15 kt. Late in the afternoon or evening the HREF is
showing some more widespread low clouds returning and these will
likely spread across the coastal areas. These will likely coincide
with the frontal boundary and some light rain. /MKK

&&

.MARINE...An approaching frontal boundary is diminishing the winds
this morning. The gale warning and hazardous seas warning are set to
expire at 8am in the north and winds will continue to diminish
through the day in the southern waters. This will allow the gale
warning to expire in the afternoon in the southern waters. A small
area of southerly winds may briefly move through the waters north of
Trinidad.

Tuesday behind the front northerly winds are expected to rapidly
return to gale force across the waters starting mid morning in the
outer waters and reaching the inner waters early the afternoon.  So
have issued gale watches to highlight this. Seas will rapidly build
due to the local winds and a large area of very strong northerly
winds to the north of the area. The combination of the fresh swell
and the wind driven waves they are expected to build to 20 to 25
feet on Wednesday. Wednesday afternoon the winds start to diminish,
but the waves will remain elevated through the night.

Thursday an upper level low and a surface low are expected to move
over the area bringing more variable winds of 10 to 15 kt. This
moves out of the area on Friday and Saturday stronger northerly
winds return. At this point it looks like the will remain below gale
force, but it could be close to gales in the outer waters. /MKK
