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 May 17, 3:11 PM PDT, 11 hours 14 minutes earlier.

Area forecast discussion, May 17, 3:11 PM PDT, 11 hours 14 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
311 PM PDT Thu May 17 2018

.SYNOPSIS...A few showers across the interior mountains will
dissipate this evening. Elsewhere, cloudy and cooler than normal
conditions will continue. Friday and Saturday will feature mainly
dry weather with possible afternoon clearing for coastal areas.

&&

.DISCUSSION...Currently looking at one more afternoon and evening
of isolated showers over the interior mountains before upper-level
high pressure temporarily builds in heading into Friday and the
weekend. Would not totally rule out a stray lightning strike with
a stronger cell over Trinity county, but honestly do not expect
it, as drier and more stable air looks to be taking over. Friday
and Saturday...A transient building ridge of high pressure will
likely be enough to severely limit shower activity thus a brief
period of drier and slightly warmer conditions are expected across
the interior. At the coast, a deep marine layer is keeping coastal
stratus in place, but northerly winds have started to clear out
areas downwind of Cape Mendocino and Cape Blanco, including
Crescent City. The next couple of afternoons may hold more promise
for partial afternoon clearing along the rest of the coast as
drier and more mixed air may have a greater influence on the
boundary layer. By Sunday and through early next week, shower
chances across the interior mountains will steadily increase as
another low pressure system approaches, this time arriving from
the northwest as opposed to the southwest. Uncertainty is very
high regarding the timing and coverage of these showers as there
is quite a bit of uncertainty regarding the track of the low.
Overall though, shower chances will be greatest toward the end of
the weekend and early next week, and as usual this time of year
will be concentrated across interior mountain ranges. Temperatures
throughout this time period will remain mild and pleasant inland,
and seasonably cool within the marine layer near the coast.

&&

.AVIATION...Plenty of low cloudiness continued across the flying
area, even as influence from an upper level trof departs the
region. A deep marine layer also continued with morning Cigs IFR-
MVFR...then MVFR-VFR in the afternoon at coastal locations. A 1:22
PM pilot report out of ACV reported cloud base Ovc030 & cloud
top037. Concur with previous discussion that moist boundary layer
conditions will continue overnight. Therefore, the marine layer
will remain persistent with Cigs/Vis mostly MVFR, but dipping
locally into IFR...especially vicinity of EKA to ACV airport. Low
clouds at UKI dissipated quite early today, so the any marine
influence should be limited with most model guidance expecting VFR
conditions Friday morning. /TA

&&

.MARINE...Northerly winds will continue to pick up this evening
and persist through the weekend with steeper seas eventually
building to 6 to 8 feet south of Cape Mendocino, thus have issued
a small craft advisory for the southern outer waters. Heading into
next week, winds may increase another 5 to 10 kt with seas
approaching 10 ft. Otherwise, northwesterly swells mixed in with
the shorter period seas will remain relatively low.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...Small Craft Advisory
until 3 AM PDT Saturday for PZZ475.
