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 Nov 19, 3:07 PM PST, 11 hours 30 minutes earlier.
Area forecast discussion, Nov 19, 3:07 PM PST, 11 hours 30 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
307 PM PST Mon Nov 19 2018
.SYNOPSIS...Dry, mild, and hazy conditions will continue through
Tuesday. In addition, breezy south winds will develop by Tuesday
afternoon, followed by significant rains Tuesday night through
Friday.
&&
.DISCUSSION...A vigorous upper low was in the process of moving
onshore over SRN CA Monday afternoon. Meanwhile, a trough
progressing toward the NERN PAC was kicking a west coast ridge
eastward. Between the upper low and trough, NWRN CA will continue
to experience pleasant, albeit hazy conditions for another 24
hours. In addition, clear skies tonight will promote frost
development for wind sheltered areas (reference the latest frost
advisory for more details).
A surface frontal wave associated with the previously mentioned
trough over the NERN PAC is forecast to approach NWRN CA during
Tuesday. South-southeast winds will become gusty ahead of the
front, with near-advisory level speeds developing across exposed
coastal ridges. In addition, southeast winds across the Eel River
delta and surrounding coast mountains will promote downslope
warming for the Humboldt Bay area. This could result in Tuesday
highs climbing into the upper 60s despite increasing cloud cover.
Frontal rains will spread across the region during Tuesday night.
Thereafter, rain will transition to post-frontal showers during
Wednesday afternoon. Steepening lapse rates associated with a cold
midlevel airmass (near -25 C at 500 mb) will develop across the
region late Wednesday afternoon into the evening. This will favor
weak but sufficient CAPE for isolated thunderstorms over the
coastal waters and adjacent inland areas. Heavier showers and
storms could also produce small hail.
After Wednesday, model guidance shows a pronounced zone of
westerly moisture flux impinging upon NWRN CA during Thursday.
Most deterministic solutions shift this zone of moisture flux
south of the region during Thursday night. However, the GFS keeps
this feature over the CWA for 12 to 18 hours, which subsequently
yields an excessive amount of rainfall that may necessitate a
flood advisory for small streams and urban areas. In addition, WSW
925 mb winds in excess of 40 kt combined with a tight southerly
surface pressure gradient will likely result in advisory level
wind speeds for coastal and ridgetop locations.
Going into the weekend...another frontal wave is forecast to
impact the PAC NW. This feature will be embedded within a zone of
midlevel height rises. Thus, only light rain and minimal impacts
are expected as it reaches NWRN CA.

.AVIATION...Improvement in cig and vsbys today as southeasterlies
gradually ramp up ahead of the first Pacific front expected to
arrive to the coast late tomorrow night. Although the southeast
winds are not strong at the surface there is enough wind aloft to
begin to finally scour and mix out the low level smoke/haze and
fog that has plagued the areas the past few days. Thus mainly vfr
conditions are being observed across the region and this should
continue through the next couple of days. There will still be a
chance of fog development tonight early tomorrow as winds decouple
but the persistent haze should diminish.
&&
.MARINE...The subdued wind and sea state continues as a very weak
pressure gradient persists across the region. This all comes to a
crashing halt beginning tomorrow night however as the first of
two fronts reaches the coast. Southerlies ahead of the first front
will ramp up beginning late tomorrow. Strongest winds will occur
over the northern waters for high end sca but a gale warning is
not anticipated. The second front arriving on Thursday will be
stronger and will likely warrant a gale for the norther outer
waters. The sea state will remain light until the wind swell picks
up from the south winds...While a westerly swell builds into
Thursday reach near 10 ft at 13 seconds late Thursday.
&&
.FIRE WEATHER...A dry airmass, characterized by afternoon RH
values in the 20s, will persist across interior NWRN CA through
much of the day Tuesday. In addition, southerly ridgetop winds
gusting to 30 mph are forecast to develop ahead of a frontal
boundary tonight into Tuesday afternoon. The gusty winds and low
RH values will yield elevated to locally critical fire weather
conditions across exposed ridges during the next 24 hours.
Widespread rain will then develop across the region Tuesday, and
potentially become heavy during Thursday afternoon.
