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 Dec 8, 2:56 PM PST, 11 hours 48 minutes earlier.

Area forecast discussion, Dec 8, 2:56 PM PST, 11 hours 48 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
256 PM PST Sun Dec 8 2019

.SYNOPSIS...Dry and mild weather is expected tonight and Monday,
with some patchy valley fog lingering through Monday morning. A weak
front will bring light rain back to the area on Tuesday, with mild
but showery weather continuing through much of the remainder of the
week.

&&

.DISCUSSION...Precipitation has mostly come to an end across
northwest California this afternoon as the upper level trough
departs to the southeast, with just a few weak showers lingering
over the higher terrain of Trinity and eastern Mendocino
Counties. A highly amplified ridge building over the west coast
tonight will support mainly dry and mild conditions through
Monday. More extensive cloud cover may linger along the coast
tonight, but partial clearing over the interior coupled with
abundant low level moisture from the recent rainfall will likely
support widespread fog development over the interior valleys
through Monday morning. Otherwise, mostly sunny skies will prevail
across much of the area during the day on Monday. This period of
dry weather will be relatively short lived as the ridge is
bisected by another shortwave approaching the BC/WA coast early in
the week, which will allow a weak upper disturbance and
corresponding front to move across northern CA on Tuesday.
Rainfall amounts with this next system look to be limited to a few
tenths of an inch between Tuesday afternoon and early Wednesday
morning, with no strong winds expected. A zonal flow pattern will
then become established over the area for the latter half of the
week, with a series of embedded waves providing occasional chances
for rain into next weekend. This could amount to an additional
few inches of rain across the northern extent of the area between
Wednesday night and Saturday, with lower amounts farther south.
That said, no major weather impacts are expected across the area
over the next seven days. /CB

&&

.AVIATION...Low clouds continue to afflict northwest California
airfields with MVFR ceilings expected to filter in and out through
the remainder of the day. Conditions will deteriorate tonight along
coastal areas and interior valleys as fog settles in and causes
ceiling and visibility restrictions. Winds will remain generally
lighter and northerly through the TAF period. However, eddies in the
low-level flow will result in periods of southerly winds, especially
for KCEC. Come Monday, expect VFR conditions with high ceilings
possible. KMZ

&&

.MARINE...Building high pressure will cause lower winds and seas to
to continue in northwest California waters through at least Monday.
Then an approaching frontal boundary will bring moderate southerly
winds for Tuesday. Small craft advisories will be likely with wind
gusts approaching 25 kt offshore and steep seas reaching 8 to 12
feet. The weather pattern will remain unsettled through the rest of
the week with additional weather systems bringing the potential for
rain. This means moderate southerly winds will continue through the
rest of the work week before increasing north winds return over the
weekend. The sea state over the next few days will be comprised
of various mid-period swells from the southwest to northwest as
well as wind-driven waves with the frontal passage on Tuesday. In
addition, there is a significant WNW swell forecast to impact
northwest California on Thursday and Friday. The sea state will
build rapidly on Thursday and peak Friday morning around 16 feet
at 18 seconds. A hazardous seas warning may be necessary if the
forecast remains on track. This swell could create dangerous
conditions in the harbor channel so stay tuned to the forecast.
