What forecasters said that day

The local office's own words before this high surf advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Los Angeles, CA wrote its last area forecast discussion before this high surf advisory went out at Dec 5, 10:23 PM PST, 3 hours 47 minutes earlier.

Area forecast discussion, Dec 5, 10:23 PM PST, 3 hours 47 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1023 PM PST Thu Dec 5 2019

.SYNOPSIS...05/746 PM.

Clouds will increase tomorrow as the next storm system approaches
bringing gusty winds and rain to San Luis Obispo County as early
as Friday morning, and into the remaining counties by Friday
night. The chance of rain will persist through Saturday, with
lingering showers possible early Sunday. Temperatures will begin
warming through Thursday as high pressure returns.

&&

.SHORT TERM (THU-SUN)...05/835 PM.

***UPDATE***

An upper level ridge over srn CA this evening will slowly move E
of the region overnight while an upper level low and its
associated large upper level trof over the E Pac slowly edges E.
Lingering low level moisture will keep varying amounts of
stratocu over portions of the forecast area overnight. There is
also plenty of hi clouds streaming into the region from the SW
this evening which will continue overnight. Overall, mostly cloudy
skies will prevail across the region tonight. Some offshore flow
will develop overnight specially over portions of VTU/L.A.
Counties but winds will be well below advisory levels. With the
clouds and breezes, overngiht low temps are expected to be mild
and significantly above normal.

***From Previous Discussion***

A very similar scenario Friday though models are a little less
moist in the lower levels than today. May see a little more
sunshine but still on the cool side. An upper low is spinning
around near 40n/140w and will only move very slowly east through
Saturday as it bumps into a weak upper ridge along the coast. We
will see moisture increasing across the area Friday night with
rain becoming increasingly likely across all of SLO/SB Counties.
And by Saturday morning or afternoon light showers should reach
most of LA County except possibly the Antelope Valley.

A second impulse will follow Sat night into Sunday morning
maintaining a good chance of precip most areas through the
weekend.

Since the upper low is expected to stay well to the north the
impacts this far south are expected to be minimal and rain
amounts and rates, except for the NW SLO hills, are expected to
be on the light side. Most areas will total under an inch with
rates typically less than .1"/hr. LA County will see the lowest
amounts, generally a half inch or less. Once again this will be a
high snow level event, hovering around 8000' Sat then lowering to
between 6000-7000' Sun.

.LONG TERM (MON-THU)...05/144 PM.

The trough is expected to move east late Sunday and Monday with
dry and warmer conditions early next week as a ridge of high
pressure moves over the west coast.

The ridge will break down Wednesday as a weak trough approaches
from the west. We'll likely see some clouds from it and a slight
cool down but no precip.

Models now in near unanimous agreement on a very strong high
pressure ridge developing over the eastern Pacific Thursday and
expanding east through Saturday. This will maintain dry weather
through the week and likely some warming, but nothing dramatic as
gradients are only lightly offshore at most and 950mb temps stay
below 20c.
