What forecasters said that day

The local office's own words before this gale warning 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 gale warning went out at Apr 18, 2:33 PM PDT, 12 hours 11 minutes earlier.

Area forecast discussion, Apr 18, 2:33 PM PDT, 12 hours 11 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
233 PM PDT Thu Apr 18 2019

.SYNOPSIS...Warmer weather is expected across the interior while
a weak trough promotes a slight chance of showers Friday through
Saturday over the eastern mountains. A dry weather and a new
warming trend will begin on Sunday...lasting through early next
week. Coastal areas will see breezy north winds during the
afternoons with a mix of low clouds and sun.

&&

.DISCUSSION...Pictures from space showing virtually cloudless
skies across NW CA this afternoon. There is a sliver of pesky
stratus and fog along the north coast but the only thing showing
up on Vis Imagery is the large amount of snow over the highest
elevations. Main weather features to deal with over the next
couple of days is enhanced cloudiness and possible drizzle tonight
and early tomorrow as the lower clouds and fog reform along the
coast tonight. This layer may get enhanced due to the presence of
an incoming short wave aloft allowing the chance of some light
drizzle to fall. The other issue is some enhanced instability
related to that upper feature which when combined with daytime
heating across the interior on Friday...cannot rule out a few
isolated lightning strikes or showers. BUFKIT soundings and
convective indices were not very impressive, however SREF (short
range ensemble forecast) calibrated probability of thunderstorms
increases to around 20% late Friday afternoon. The threat may
persist into the early morning hours of Saturday as the 500mb cold
pool drops over the area from the NW. One conflicting consideration
that may counter that heating is the large amount of snow that is
still present over those areas. Other than a slight cool down on
Saturday some very nice spring temperatures will be observed
across the interior beginning Sunday. Expect highs to reach the
80s in the interior valleys today under bright April sunshine.
Unfortunately, coastal areas will not see any warming today due to
the marine stratus. The Mendocino coast stands the best chance of
warming as that area may not be as influenced by the lingering
stratus. As for precip chances, it is not looking very promising
for any precip through mid next week. Ensemble blend indicates low
precip chances late next week, however the ridge is firmly in
place and it may end up remaining dry through the end of next
week.

&&

.AVIATION...Widespread VFR conditions are being observed across
NW CA this afternoon. Coastal areas will see a return of the low
clouds this evening and these clouds and/or fog should be a
little more stubborn tomorrow as a weak wave aloft helps support
marine layer depth. Thus expect mvfr conditions due to cig and or
vsby through mid to late morning before gradually giving way to
vfr cigs by early afternoon. Interior valley terminals will also
see another morning of low clouds and fog but like today...these
sites should be vfr by mid morning.

&&

.MARINE...Light to moderate northerlies will persist through Friday
morning, with winds expected to be a little stronger south of Cape
Mendocino. Northerlies will begin to increase Friday evening and
continue to increase to Gale Force in strength on Saturday across
the outer waters. A Gale Watch has been issued for the outer
waters to reflect this. Winds will remain elevated through early
Sunday and are forecast to weaken throughout the day on Sunday.
Steep, short- period seas will develop as a result of the
increasing northerlies. Additionally, a long-period northwest
swell has moved through the coastal waters. This swell will
persist through Friday before weakening this weekend.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...Gale Watch from Saturday morning through late Saturday night for
     PZZ470-475.

     Small Craft Advisory from 9 PM Friday to 8 AM PDT Saturday for
     PZZ470-475.
