What forecasters said that day

The local office's own words before this wind 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 wind advisory went out at Nov 18, 4:05 PM PST, 12 hours 12 minutes earlier.

Area forecast discussion, Nov 18, 4:05 PM PST, 12 hours 12 minutes before
AREA FORECAST DISCUSSION...CORRECTED
National Weather Service Eureka
CA 405 PM PST Mon Nov 18 2024

.SYNOPSIS...Scattered showers continue to move onshore along the
coast today. Strong winds develop Tuesday afternoon and evening as
the next storm approaches. Steady, moderate rain, with embedded
heavy rainfall is forecast Wednesday into next weekend. Heavy
snow is possible in NE Trinity Wednesday.

&&

.DISCUSSION...Latest IR satellite imagery depicts a large swath
of cool cloud tops and convective showers over the NEPAC this
afternoon. Isolated showers continue this afternoon, and isolated
to scattered showers will continue tonight. Some showers and
thunderstorms contained small hail today. Local observations show
snow levels currently around 2500 ft, and these are and these are
forecast to slowly rise to 3k to 3.5k ft through this evening.
Shower activity should weaken late tonight as warm air advection
in advance of the next storm begins.

A significantly more potent storm system is forecast to impact the
region tomorrow through this weekend. Ensemble guidance continues to
hold steady on the general pattern, with all clusters depicting an
atmospheric river developing offshore Tuesday and parking itself
over NWRN CA Tuesday night through late in the week, possibly into
the weekend. This will bring a prolonged period of moderate rainfall
with an initial threat of small stream and urban flooding
Wednesday and Thursday, and potentially main stem river concerns
later in the week. A flood watch has been issued for most of the
area in response, see the Hydrology section for more details.

The initial front is forecast to bring a tight pressure gradient to
the coastal counties with very strong southerly winds Tuesday
evening. Sustained winds of 35 to 45 mph with gusts of 60 to 70 mph
are expected on exposed ridges, coastal headlands, and portions of
the coastal plain in Humboldt and Del Norte counties. A High Wind
Warning has been issued for these areas, as downed trees, power
outages, and difficult travel conditions are likely. The strongest
winds are expected just ahead of the frontal passage, as incoming
rain mixes down stronger winds present just above the surface...this
is currently forecast to occur late Tuesday night. Winds then weaken
but remain southerly around 10 to 20 kts behind the front on
Wednesday.

Meanwhile, a few deterministic models (GFS, NAM, ECMWF) continue to
depict cold air getting trapped in Trinity county on Tuesday night
and Wednesday morning as this system approaches, which may allow for
heavy snow in the northeastern portions of Trinity county before
warmer air can move in. This looks most likely east of the Alps and
around Trinity Lake, as well as over Buckhorn Summit and Oregon Mtn,
however may reach as far south as Highway 36. Some uncertainty
remains on just how low snow levels will get. Most guidance agrees
they'll reach at least 3000 ft in NE Trinity Wednesday morning, and
a small but significant portion of the guidance indicates heavy snow
down to Weaverville at this time. Thus have expanded the watch to
include areas above 2000 ft. Some guidance also indicates this
colder air at the surface may linger through Wednesday into Thursday
around Trinity Lake and in the Horn...which means heavy snow could
continue for over 24 hrs on portions of Highway 3 north of
Weaverville. Should this occur, one to multiple feet of snow are
possible Wednesday and Thursday on portions of Highway 3 and 299.
This could significantly impact travel Wednesday. Confidence is
lower on snow levels for areas to the south and east, but there's
about a 50% chance over over 6 inches of snow falling on portions
of Highway 36 east of Forest Glen, so have expanded the Winter
Storm Watch to include these areas.

A secondary surface cyclone will form along the parent trough
Thursday and sweep by the coast through Thursday night. This
second system looks to better align the highest moisture flux and
IVT values Thursday and Thursday night, or into Friday morning.
Winds and precipitation have trended stronger for this system,
and it now looks like some of the highest rainfall rates may fall
through that period for some locations. This portion of the
forecast needs to also be watched closely since grounds will be
further saturated. WPC holds a Moderate Risk for flash flooding
Wednesday and Thursday, and trees and loosened branches weakened
from Tuesday and Wednesday's winds may be more prone to falling.
Clusters are not resolved on the final departure of the troughs
and rainfall period, which potentially lingers into the weekend.
TDJ/JJW

&&

.AVIATION...Since late morning, a few weather perturbations have been
responsible for a progression of convection across the North Coast.
Showers and a couple of thunderstorms (at/vicinity of the coastal
locations) often impacted the Taf sites. Small hail and lightning
were captured by radar, satellite and/or ground truth observations.
However, Cig/Vis generally remained VFR except in a few moderate-
heavy downpours. Winds became more southerly at the coast after
noonday, but were mostly west to northwest over the inland valleys
such as UKI. Showers will be 'here and there' throughout the
evening. Another approaching frontal system on Tuesday will bring
more significant weather conditions to the air terminals; Cig/Vis
will be more impacting with ongoing rains, and southeast-south
surface winds will rev up substantially. Rain will spread across the
entire region. /TA

&&

.MARINE...Winds have a had a brief reprieve before an actual storm
arrives. Winds veer southerly tonight as a storm approaches. Storm
warnings have been hoisted as winds ramp up before Tuesday afternoon
ahead of an approaching front. Storm force wind gusts (48 - 63kts)
with isolated areas reaching Hurricane force gusts (>64kts) in the
northern outer waters will make for treacherous, unruly conditions.
This will spread to all area waters as Wednesday evening approaches,
and so SR.W has been hoisted for all area waters through early
Wednesday morning.

Significant wave heights will be further elevated to 22 to 27 feet
at 12 to 13 seconds early Wednesday morning in response to these
winds. Northern zones will likely see the larger end of these wave
heights corresponding to the strongest winds offshore, while the
southern waters will experience slightly reduced 18 to 22 foot wave
heights. An additional near-shore swell will maintain 12 to 14 foot
seas through late week even as the most severe winds diminish.

.HYDROLOGY...A moderate to strong atmospheric river is forecast
to move over NWRN CA late Tuesday and persist through the rest of
the week. NAEFS mean IVT is showing a prolonged period of
anomalously high values (500 to 800 kg/ms) from the SW,
perpendicular to the local terrain. This will likely lead to a
prolonged period of persistent rainfall this week, further enhanced
by the local orography. Latest QPF guidance is showing 4 to 8 inches
of precip falling Wednesday and Thursday across the CWA from Tuesday
night through Thursday night, with rain likely continuing into the
weekend.

Latest MRMS soil moisture modeling is indicating 50% to 70%
saturated soils at the moment in Humboldt and Del Norte, with 20% to
30% in Mendocino and Lake Counties. Thus the initial bands of precip
late Tuesday night and Wednesday likely will be absorbed, however
with the prolonged nature of this incoming system, saturation is
likely, leading to enhanced runoff. This may initially lead to small
streams and creeks flooding, as well as flooding in urban areas.
Main stem rivers are forecast to respond late this week to the
persistent rainfall as well, however just how high they will reach
remains uncertain.
