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.

Area forecast discussion, Dec 24, 3:01 PM PST, 12 hours 53 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
301 PM PST Mon Dec 24 2018
.SYNOPSIS...Showers will dissipate across the region tonight,
followed by mainly dry weather during Christmas. Additional rain
will be possible midweek, and again on Sunday.
&&
.DISCUSSION...A cold upper low was moving east across the Redwood
Coast Monday afternoon. Vigorous showers and embedded
thunderstorms were occurring with the low, with stronger showers
and storms capable of producing small hail and winds gusting to
40 mph. Showers and storms are forecast to dissipate this evening
as the upper low moves east and large-scale subsidence increases
in its wake. In addition, the recent rains combined with
decreasing cloud cover tonight may support radiational fog
development toward sunrise Tuesday. Thereafter, further drying in
the boundary layer and continued clear skies Tuesday night into
Wednesday morning will support cold low temperatures favorable for
frost in the vicinity of Humboldt Bay, coastal Mendocino county,
and areas inland.
Otherwise, a frontal boundary is forecast to enter the region
during midweek. However, ascent and moisture are expected to be
weak along the front...thus precipitation will be light Wednesday
afternoon through Thursday morning. High pressure then rebuilds
over the NERN PAC Friday and Saturday resulting in mainly dry
weather and seasonable temperatures. Model guidance shows the high
breaking down Saturday night into Sunday as an upper trough moves
east across the region, which will favor another period of
frontal rains.
JMG
&&
.AVIATION...Conditions have generally improved towards VFR or
MVFR this afternoon at each of the terminals as the front moves
through the area, however periods of MVFR/IFR ceilings and
visibility will remain possible through early evening as scattered
shower activity continues across northwest CA. After a period of
stronger W-SW winds with the passage of the front, winds will
generally be much lighter (5 to 10 knots) this afternoon before
veering around to the north and increasing this evening as low
pressure passes south of the area. /CB
&&
.MARINE...Winds will be on the increase this evening across the
coastal waters as they veer around from west-southwest to more of
a northerly direction. Cold advection behind the departing system
will bring widespread gale force gusts to the outer waters
tonight, with short period seas rapidly building to 8-10 ft in
response. This will be coupled with a decaying mid-period westerly
swell on the order of 10 to 13 ft to bring treacherous seas to
the inner and outer waters through Tuesday morning. Seas will
improve somewhat by Tuesday afternoon as winds and short period
seas trend down while the swell continues to diminish, however
seas will remain elevated enough to support Small Craft Advisories
through at least Tuesday evening. Another smaller mid period NW
swell will enter the waters by Wednesday, with additional swell
trains arriving through the end of the week. Winds and short
period seas will begin to increase again Wednesday night into
Thursday with the arrival of the next system. /CB
&&
