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 Jan 6, 3:07 PM PST, 5 hours 40 minutes earlier.

Area forecast discussion, Jan 6, 3:07 PM PST, 5 hours 40 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
307 PM PST Sat Jan 6 2018

.SYNOPSIS...Cool and dry conditions can be expected tonight and
Sunday, but wet weather will return Sunday night through Tuesday.
Periodic light rain will continue in Humboldt and Del Norte
counties Wednesday and Thursday, with dry conditions farther
south. Dry weather will return to the whole region Friday through
the weekend.

&&

.DISCUSSION...High pressure has reclaimed Northwest California for
the time-being, and as a result showers have diminished across
the region. Some lingering instability continues to generate
shallow convection across the waters, but this activity has ceased
on land as of early this afternoon. Overnight tonight,
increasingly dry air aloft will result in clearing skies, which
will in turn allow for more efficient cooling along valley floors.
As a result, temperatures in interior valleys are likely to be
quite cool, with valley fog and stratus likely to develop after
midnight as well. In addition, some patchy marine stratus and fog
may develop overnight in the coastal lowlands as well. On Sunday,
dry conditions will persist, with generally cool afternoon
temperatures. High level cloud cover will steadily increase
through the day, which may help to slow the erosion of valley fog
in interior valleys. Should this occur, these areas will likely
remain very cool through the day. Meanwhile, marine stratus will
likely dissipate somewhat through the afternoon, but there are
indications that it will likely not disappear completely,
resulting in a somewhat gloomy day in some places.

Wet weather conditions can be expected late Sunday night through
Tuesday as an complex storm system approaches the area. This storm
system will actually be the end result of a merger between two
separate storm systems: one currently digging southeastward out
of the north Pacific, and a weaker, warmer system currently
located well offshore to the southwest of California. As the first
and stronger storm system digs to the south, it will absorb the
second storm system, and draw rich moisture toward California from
the subtropics. While this moisture will be plentiful, it will
not be particularly well focused in any one area. As a result,
widespread light to moderate rain will develop across much of the
state of California as a warm front moves onshore Sunday night
through early Monday. Rain rates will increase through the day
Monday as the core of the storm system moves onshore, becoming
more focused and heavy ahead of a north/south oriented cold front.
While this will help to focus and intensify precipitation from
Mendocino county southward, total accumulations will largely be
driven by terrain features and will otherwise be relatively
uniformly distributed throughout the state.

In any case, the end result for our northwest corner of
California will likely be widespread accumulations of 1 to 3
inches, with higher totals in the mountains of Mendocino and
southern Humboldt counties, and lower totals in the coastal areas
of Humboldt and Del Norte counties where southeast winds will
result in downslope evaporation. Rain will continue most of the
day Monday and into Tuesday morning, becoming showery and
gradually waning through the day Tuesday. Expect relatively minor
nuisance impacts...i.e. ponding water on roads, briefly swollen
creeks and streams, falling rocks on roads, and gusty ridgetop
winds. Snow levels will remain high throughout the event,
confining snow to the higher peaks of the Trinity Alps for the
most part and above local highway passes.

High pressure will gradually build back up along the West Coast
Wednesday and beyond, but a few weak weather systems skirting the
periphery of this high pressure may bring light rain to Humboldt
and Del Norte counties Wednesday and Thursday before things dry
out completely Friday through the weekend. /BRC

.AVIATION...VFR conditions have been prevailing this afternoon as
a brief period of high pressure has taken hold of the forecast.
There is some instability in the air; however, as satellite
imagery shows cumulus development over the terrain. These
conditions are expected to give way to the development of low
level cloud and fog later this evening, especially for the valleys
and coastal locations leaving them with IFR to LIFR conditions
tonight. The toughest part of the forecast package this afternoon
will be determining whether or not we will be able to see any
clearing tomorrow before the rain arrives. High clouds filtering
overhead may lead to less mixing which means the stratus and fog
could linger all day.

&&

.MARINE...The forecast remains on track this afternoon with buoys
reporting 7 to 8 foot waves at 13 seconds as the west-northwest
swell continues to subside. Northerly winds remain light to
moderate but will gradually weaken and shift to the south as a
storm system approaches the area from the southwest on Sunday.
This frontal boundary will bring increasing southerly winds to
the waters on Monday; however, an area of low pressure will be
moving along the front Monday afternoon This makes confidence
lower on the wind speed and direction. Areas of gale force winds
are possible with this low pressure. Tuesday morning once this
front moves through there is good agreement on a dramatic wind
shift with near gale to gale force northerly winds spreading
across the waters.

Additionally, on Monday, a second northwest swell moves into the
waters. Initially periods will be around 20 seconds and these will
diminish to around 16 seconds as it builds to around 9 feet. This
swell will slowly diminish but generally persist through late in
the week. Late in the week another long period swell is expected.

Mid to late week there is general agreement in the models that a
series of fairly weak systems will move through the waters
bringing periods of alternating northerly and southerly winds.
