What forecasters said that day

The local office's own words before this gale warning 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 gale warning went out at Jan 10, 5:04 AM PST, 4 hours 38 minutes earlier.

Area forecast discussion, Jan 10, 5:04 AM PST, 4 hours 38 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
504 AM PST Thu Jan 10 2019

.SYNOPSIS...Mainly dry conditions will prevail today as rain
showers diminish across the area. More rain is expected on Friday,
particularly south of Cape Mendocino. Additional rain will be
possible Sunday into Monday after another brief dry period on
Saturday.

&&

.DISCUSSION...Shower activity is winding down across northwest
California this morning as the upper trough shifts east of the
area and is quickly replaced by a building ridge over the western
CONUS. This will yield mostly dry conditions through Friday
morning, although a few showers may linger into this afternoon
over eastern portions of Trinity County. The next chance of rain
will arrive on Friday as another trough approaches the CA coast.
This system looks to provide more of a glancing blow to northwest
CA as the bulk of the energy slides well south of the area and
southeast winds introduce some downslope flow. The bulk of the
rain at this time looks to be confined to areas south of Cape
Mendocino, with lower probabilities and lighter amounts farther
north along the Redwood Coast. A relatively brief period of gusty
southeast winds will also be possible late Friday afternoon along
the higher terrain of Mendocino County, however it appears this
will be mitigated at least somewhat by an inversion preventing the
strongest winds aloft from mixing down to the surface. Will
continue to monitor advisory potential in the next 24-36 hours.
Rain will once again taper off overnight Friday, yielding a benign
mostly cloudy regime with a slight chance of showers through
Saturday. /CB

.Long Term (Sunday through Wednesday)...Uncertainty abounds in
the long term forecast, owing to the development of a large ridge
of high pressure across the western U.S. As this ridge builds, the
jet stream will split into two forks, one of which will undercut
the ridge at its base and essentially direct incoming storm
systems to the south and away from N CA, a pattern closely
resembling a blocking pattern called a "rex block". During this
time, the approaching storm systems are expected to weaken and
turn toward the south as they near the CA Coast, which will place
the focus of heavier precipitation farther south as well. However,
this is not to say that NW CA will stay completely dry. While we
may not see the full force of these storms, at least some light
rain is expected to reach the area with each system, most likely
on Sunday into early Monday. Uncertainty is very high regarding
this system given the pattern change.

Beyond Monday, uncertainty increases even more as it appears that
the west coast longwave ridge may begin to weaken and slide a bit
farther to the west. Should this occur, NW CA would likely be
exposed to a more active storm track, bringing more rain to the
region. /BRC&SEC

&&

.AVIATION...Spotty showers will taper off by mid-morning, with dry
conditions expected through late Friday morning as high pressure
moves over the area. Low clouds and inland valley fog across the
interior have formed overnight, with KUKI impacted. These areas
should burn off by late morning, though confidence is low on exact
timing. Mostly VFR to MVFR conditions are expected at all terminals
this afternoon and evening, though some gusty conditions may develop
once again along the coast. Otherwise, cloud cover will retreat
throughout the day today before returning late tonight. Valley fog
and low clouds will be possible again tonight across the interior,
with possible impacts at KUKI. Light offshore flow should keep
coastal terminals mostly clear overnight.

&&

.MARINE...Southerly winds will increase across the outer waters
this morning as the next system approaches. Gale force gusts will be
possible Friday morning through Friday afternoon, mostly over the
southern outer waters. As a result, have issued a Gale Watch for the
southern outer waters beginning early Friday morning and continuing
through Friday afternoon. Winds will begin to weaken Friday evening
and continue to weaken through Saturday morning. Southerlies will
again increase across the outer waters and around Cape Mendocino
overnight on Saturday and begin to weaken Sunday afternoon.
Afterwards, much calmer winds will persist through early next week.
Winds will increase once again on Wednesday and are forecast to
weaken by Thursday morning.

Small Craft Advisories for all coastal zones are in place through
this afternoon, and have extended the advisories for both of the
outer waters and the southern inner waters through Friday afternoon.
Though, the Small Craft Advisory for the southern outer waters will
expire when the Gale Watch goes into effect early on Friday.
Otherwise, the advisories for the northern outer and southern inner
are set to go through Friday afternoon.

Steep short-period southerly waves will ramp up today with the
increasing winds. A waning westerly swell will persist across the
waters through Friday as another west to northwest swell begins to
move through the waters tonight. An additional west to southwest
swell will begin to move through the waters Friday evening and build
through Saturday morning. Seas are expected to remain chaotic
through the weekend, with additional storm systems expected to
impact the area.

&&

.BEACH HAZARDS...A long-period westerly swell will pose a
moderate to high threat for sneaker waves Sunday morning through
Monday morning, mainly north of Cape Mendocino. A Beach Hazard
Statement will likely be needed as we near the event. Beachgoers
are urged to use extreme caution while on beaches and to keep a
respectful distance from the ocean. Never turn your back on the
ocean.

.EKA WATCHES/WARNINGS/ADVISORIES...
