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 Mar 20, 3:00 PM PDT, 11 hours 39 minutes earlier.

Area forecast discussion, Mar 20, 3:00 PM PDT, 11 hours 39 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
300 PM PDT Wed Mar 20 2024

.SYNOPSIS...Rain and moderate south wind will build across the area
Thursday night through Friday. Rain showers will then persist
through Saturday mostly along the North Coast. Periods of rain will
continue through mid next week.

&&

.DISCUSSION...Surface high pressure is continuing to weaken and move
east of the area. Meanwhile, a weak shortwave aloft is evident along
shore early this afternoon, highlighted by high and midlevel clouds
on satellite imagery. This shortwave has signaled the end of warm
and sunny weather as clouds are beginning to build across the
interior. This pattern is already evident in cooler temperatures
across inland valleys.

The upper level shortwave will continue to cross the area overnight.
Despite some instability aloft, generally meager moisture will limit
precipitation to cloud cover and light coastal drizzle at most. This
will change late this week. A much deeper, cutoff trough will slowly
approach shore this weekend. Warm, moist air will advect in front of
the trough. ECMWF EFI indicates the strongest rain will stall
offshore, but a burst of precipitation remains on track early and
then through the day on Friday. Rain will be strongest as a surface
cold front sweeps across the area. 1 to 2 inches of rain is most
likely along high terrain of the north coast with 0.5 to 1.0 inches
at lower elevations. Lower elevations include the Humboldt Bay area
where the pattern will favor a moderate downsloping effect. NBM
shows a 60 to 80% chance of southerly gusts along the front in
excess of 35 mph, but only a 20 to 30% chance of gusts over 45 mph
even along high terrain. This generally moderate wind will limit the
risk of any wind impacts.

Cold air aloft behind the front will increase instability with
marginal instability of 50 to 100 J/Kg of CAPE. This instability
will be sufficient to maintain rainshowers through Saturday. Rain
showers will be less bound to the terrain than the initial wave of
stratiform rain with an additional 1 to 2 inches of rain across
Humboldt and Del Norte Counties with closer to 0.5 inches most
likely elsewhere. Instability could allow for some isolated
thunderstorms (10 to 20% chance) over the waters and right along
shore, but any storms will be weak and short lived with minimal hail
risk.

Warm air advection will help keep snow levels above 5000 feet with
the first round of rain Friday with any snowfall restricted only to
high mountain peaks. Snow levels will begin to fall early Saturday
morning especially in areas of upslope wind in Trinity County. NBM
shows a most likely snow level range of 3500 to 4000 feet. This
could help bring 6 to 12 inches of wet snow to the highest
elevations of Highway 3 in Trinity County with 1 to 2 inches
possible along Highway 36. Any snow will be inconsistent with mostly
limited impacts.

Essentially all ensemble models show a break in rain early next weak
with a quick hitting but weak trough mid next week. This would bring
another round of mostly light rain. ECMWF EFI does not highlight any
really anomalous weather through mid next week. /JHW

&&

.AVIATION...Southerly winds will ramp up, mostly at the coastal
terminals, into this evening as a weak front approaches. Gentle to
moderate breezes are expected. While the front may be weak, it will
keep visibility up along the coast with the lowest ceilings at MVFR
overnight. Some light rain is possible for the coastal terminals
early tomorrow morning, most likely occurring in Del Norte County.
VFR conditions are expected for the interior with overcast
conditions by this evening.

&&

.MARINE...Southerly winds will continue to ramp up across the waters
as a weak front approaches. Winds are expected to peak in the
northern outer waters tonight. Gusts to 25 kt are possible in the
northern outer waters, but for the most part lower end small craft
winds are expected. In addition to the winds, a northwesterly swell
will move through at around 5 feet at 15 seconds. This is expected
to slowly diminish through the night.

Lighter winds are expected tomorrow; however, by tomorrow night,
another system will approach the area. Early Friday morning,
southerlies are expected to increase again. Gale force gusts could
occur in the lee of Cape Mendocino. Swell is expected to build
through the day tomorrow with waves anticipated to peak around 3 to
5 feet. After frontal passage on Friday, winds may diminish some,
but will remain elevated through Saturday afternoon. Saturday night
through Monday, northerly winds are expected in the 15 to 25 kt
range.
