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 5, 3:46 AM PDT, 10 hours 32 minutes earlier.

Area forecast discussion, Apr 5, 3:46 AM PDT, 10 hours 32 minutes before

AREA FORECAST DISCUSSION
National Weather Service Eureka CA
346 AM PDT Tue Apr 5 2022

.SYNOPSIS...Dry weather is forecast today through Thursday. Daytime
high temperatures are expected to warm well above normal on
Wednesday and again on Thursday. A cooling trend with periods of
blustery winds are forecast Friday through Monday.

&&

.DISCUSSION...Satellite imagery showed plenty of low level clouds
spread out across many of the interior valleys early this morning.
There is just too much low level moist air and low clouds to pose
a significant threat for frost this morning and all advisories
have been cancelled. Clearer skies and lower dewpoints will pose
a higher risk for frost formation tonight, mainly where northerly
winds completely decouple. The mitigating factor will be a
warming air mass which should offset the longwave cooling. Strong
nocturnal inversions will likely form over the valley floors and
completely decouple from the deep layer warming.

Some warming is expected today. Much more substantial warming is
anticipated for the interior on Wednesday and again on Thursday as
upper ridging builds over NW California. Highs in the 80s are
generally expected for many of the valleys. A few warmer sites
such as Ukiah should hit 90F or more on Thu. Records for Ukiah are
in the mid 90's and right now the chance for 95F or more is only
around 30%. Light offshore flow should keep stratus and fog to a
minimum and slight warming for the coast is also expected. Also,
northerlies should not be as gusty on Wednesday and Thursday.
Northerlies along the coast will probably gust to 19-28 mph
today, and 12-19 mph on Wed and Thu.

A cooling trend will begin on Friday as a transient shortwave
trough knocks down the ridge. This shortwave trough does not pose
a significant chance for rain (10% or less), however it will
induce a push of marine air and low clouds. NBM guidance as well
as raw ensemble guidance indicates northerlies ramping up in the
wake this trough on Friday. Northerlies may gust up to 28-35 mph
in the afternoon/evening. These diurnal northerlies and
northwesterlies will likely persist into the weekend and probably
into Monday of next week. The air mass will also cool down over
the weekend, increasing the risk for frost and freezing
temperatures, especially for interior valleys. The chance of rain
and low elevation snow will also increase, however there is
considerable variability and uncertainty with the depth, evolution
and progression of the cold core aloft. Current multi-model
guidance indicates 10-20% probabilities for an inch or more of
snow in 24 hours, above 1500-2500 feet for Del Norte and Humboldt
Counties. Impactful winter weather with low snow levels for
Northwest California is possible. Sub-freezing early morning
temperatures in the valleys of Del Norte, Humboldt, Mendocino and
Lake Counties are much more probable, especially Sun and Mon.

&&

.AVIATION...Visibilities have bounced around overnight and hopping
around between IFR to MVFR along the coast. Expect this trend to
continue through most of this morning. Current guidances suggests
that VFR conditions can be expected this afternoon and this evening,
though some MVFR conditions will certainly be possible. Winds will
be breezy along the coast this afternoon, with sustained winds
topping out around 15 knots or so. Otherwise, VFR conditions should
prevail through the period at KUKI.

&&

.MARINE...A larger northwest swell, with a period at 15 to 16
seconds, will peak this morning around 15 to 17 feet and then slowly
diminish through the rest of the work week. Northerlies will ramp up
from south to north today over the coastal waters. Steeper, short-
period seas will build in response to the increasing winds. Winds
will begin a weakening trend tomorrow and continue the downward
trend through Thursday. Another increase is expected for Friday and
into the weekend, with winds topping out around near gales to gales
over the outer waters. Mostly strong breezes are expected over the
inner waters, though around Point Saint George and Cape Mendocino
will likely see near gales. Winds are forecast to weaken as we head
into Sunday and should continue to diminish into early next week.

&&

.BEACH HAZARDS...A larger northwest swell is forecast to bring some
breaking waves to around 20 feet to area beaches this morning. Our
criteria for a High Surf Advisory is 22 feet, so at this time the
forecast breaking waves fall just short of criteria. If waves come
in 2 feet larger than forecast they would hit our advisory criteria
in the northern portions of the area. MKK
