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 Apr 9, 2:48 PM PDT, 11 hours 44 minutes earlier.
Area forecast discussion, Apr 9, 2:48 PM PDT, 11 hours 44 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
248 PM PDT Sun Apr 9 2023
.SYNOPSIS...Warm to near normal temperatures will continue across
the interior valleys through Monday. Midlevel clouds will fill in
along the coast, bringing a chance of light drizzle or sprinkles
to those areas...with steadier rain likely to arrive to the
coastal areas north of Cape Mendocino tomorrow afternoon.
&&
.DISCUSSION...A slow moving push of midlevel and high level
clouds onshore ahead of a quasi stationary front sitting just off
the coast will continue across the north coast region. Light
drizzle or sprinkles are possible as clouds moving onshore are
enhanced by the terrain. The front will finally push inland
tomorrow afternoon with light rain arriving and lasting into early
Tuesday with as much as 0.5 to 1.5 inches of rain with the
heaviest rain restricted to Del Norte County. There remains only a
15 to 25% chance of any more than 0.1 inches of rain anywhere in
Mendocino and Trinity counties. There is a 0% chance in Lake
County. The pressure gradient aloft is meager, keeping even the
highest gusts below 30 mph as the system passes. Cold air
advection and clear skies associated with the system will bring
another round of freezing temperatures by Tuesday night, though
meager moisture transport at that point will limit the risk of any
winter weather. Even as snow levels drop below 2000 feet, there
is essentially no risk of any snow accumulation above 1 inch.
There is 40 to 60% chance of freezing low temperatures along the
101 corridor Wednesday and Friday mornings. There is a similar
chance of patchy frost along the coast. High pressure building
over the east Pacific will also support robust sea breezes each
afternoon Wednesday through Friday, bringing coastal gusts as high
as 30 mph. Despite onshore wind, cold air aloft will restrict the
formation of any marine layer, bringing generally pleasant
coastal conditions. Essentially all model ensemble members
currently bring a weak transient ridge over the area between next
Friday and Sunday. This pattern would bring another warm weekend,
though the weakness of the ridge will likely only allow warm
temperatures back into the 70s at the most. /JHW/JT
&&
.AVIATION...Pre frontal strato cumulus clouds are funneling
towards the Pacific NW, filling cloud groups into overcast
conditions at the coastal terminals. Mid level cloud groups around
8,000 feet, and lower clouds around 3,000 to 4,000 feet will
continue to gather density as the stalled front offshore delays
passage until Monday early afternoon. Light rain could make its way
to KCEC by the early evening as model data and current radar returns
indicate. Light southerly winds and MVFR conditions are likely
considering the ceilings will lower tonight at KCEC and KACV. Light
winds and high ceilings at KUKI will prevail and keep flight
categories in VFR through the TAF period. /EYS
&&
.MARINE...Short period southerly wind waves will eventually ease
tonight while WNW swell continues around 10 feet at 15 seconds,
north of Cape Mendocino. Light rain is expected also tonight in the
northern outer waters as a stalled front persists. The front will
stall offshore this evening and winds should slacken up some
overnight. This frontal boundary will then move across the waters on
Monday and southerly winds and wind waves will increase again. Winds
will shift to NW and increase behind the front Monday night and Tue,
with possible advisory level speeds south of Cape Mendocino on Tue.
Northerlies will ramp up south of Cape Mendo on Tue and then
throughout on Wed after trough passage. Near gale conditions with
gusts around 35-40kt are probable Wed afternoon and evening, mostly
south of Cape Mendo. Conditions will remain elevated on Thu, but
should ease Thu night. A NW swell will build to 8-10 feet at 15
seconds today through this evening and then gradually decay through
mid next week. /EYS
