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 4, 2:45 PM PST, 5 hours 24 minutes earlier.

Area forecast discussion, Feb 4, 2:45 PM PST, 5 hours 24 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
245 PM PST Tue Feb 4 2020

.SYNOPSIS...Low temperatures tonight will be a few degrees warmer
than last night in most locations. A warm front will pass to our
north on Wednesday, bringing an increase in cloudiness to
northern portions of our area. Otherwise, high pressure will
remain in control through Friday with moderating temperatures,
some sunshine, and light winds.

&&

.DISCUSSION...After the coldest night of the year in most
locations, temperatures have rebounded into the 40s and 50s in
most locations other than the interior mountains. Mid and high
clouds continue to infiltrate the area from the N.

The weather over the next 7 days will continue to be notably dull
compared to what we typically expect of February in NW CA. Strong
high pressure both at the surface and aloft over the eastern
Pacific will dominate our weather through much of this week and
even into the next.

Tonight will be several degrees milder than last night across most
of the area. The mid and high clouds may aid in keeping
temperatures up, but feel there will be periodic breaks in the
cloudiness through most of the night. A plume of Pacific moisture
and warm air advection will take aim at the Pacific NW on
Wednesday, but will miss our area to the N (other than a few
sprinkles or very light rain showers over portions of Del Norte
County). Coastal clouds may linger into parts of Thursday or
Friday, but, otherwise, expect plentiful sunshine for the end of
the work week. With high pressure continuing to build in, warmer
air aloft will bring moderating temperatures with generally light
winds Wednesday through Friday.

A more potent shortwave trough will try to approach our area from
the north on Saturday, but will struggle to bring more than some
light showers into the northern portions of our area Saturday
through Sunday morning. Either way, expect some increase in
clouds for the weekend, with somewhat cooler temperatures
accompanying another shot of brisk northerly winds. /AAD&SEC

&&

.AVIATION...The coastal TAF sites reported dry offshore flow this
morning which resulted in SKC and no fog development. Inland
valleys also remained SKC under mostly calm winds. Pressure
gradient interaction between building offshore high pressure and
the onshore inverted trough is the catalyst for afternoon breezy
conditions along the coast. A dirty ridge brought in a plethora of
high clouds at various levels as seen on satellite. Also,
afternoon satellite imagery showed distant mid-level clouds which
model data indicating altocumulus advecting over the North Coast
this evening. In the morning, a weak trough will move over the
Oregon Coast and possibly brush across far Del Norte. This will
allow for MVFR conditions at CEC in the morning, including a brief
slight chance of drizzle/light rain associated with the tail end
of the trof. /TA

&&

.MARINE...The strong northerly wind regime will trend downward
somewhat over the next 24 to 48 hours as high pressure slowly
weakens offshore and relaxes the coastal pressure gradient. This
will allow gale force gusts to diminish through this evening, with
short period seas slowly coming down in response through Thursday.
Meanwhile, another NW swell will enter the waters tonight and linger
close to 10 feet at around 15 seconds through Wednesday evening
before slowly diminishing through the rest of the week. A short
duration Hazardous Seas Warning may be needed tonight for the
southern outer zone once the gales come to an end but before the
short period wave group has had a chance to subside. Otherwise,
Small Craft Advisory conditions will persist over most of the
coastal waters through Wednesday, with potential for marginally
better conditions through the rest of the work week as moderate to
fresh northerlies remain in place. /CB
