What forecasters said that day

The local office's own words before this wind 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 wind advisory went out at Jan 7, 7:23 PM PST, 28 minutes earlier.

Area forecast discussion, Jan 7, 7:23 PM PST, 28 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
723 PM PST Sun Jan 7 2018

.SYNOPSIS...
Dry and mild weather through tonight. A strong storm system Monday
and Tuesday will bring significant rain, mountain snow, gusty
winds, and a slight chance of thunderstorms to the region. Debris
flows across the recent burn areas are possible with the heavy
rain. Gusty northerly winds and a diminishing shower threat on
Wednesday will be followed by dry weather and a warming trend into
the weekend.

&&

.UPDATE...

Currently things are just setting up for the big event. The trof
is still to the west and todays ridge is shifting out of the
state. There are some echos on the radar over the waters but these
are likely precip aloft and not hitting the ground. While there
may be a few drops of rain before midnight it looks like any
steady rain that develops in the warm sector will not occur until
after midnight.

Forecast is on track. The forecast will be updated to add wind
advisories to most areas. The storm is still on track. The 00Z
mdls do show the core of the upper low now moving from SBA county
through LA county from 18Z Tue to 03Z Wed. This will make the
chance of post frontal TSTMs more likely.

The very high resolution mdls are just beginning to capture this
event and they are hinting that there may be even more rainfall
than currently forecast for the north slopes. Will analyze these
new mdl runs as they come in late this evening and adjust the
morning forecast as necessary.

&&

.SHORT TERM...(SUN-WED)

Ridging aloft continues to move east of the area this afternoon.
Southwest flow aloft continues to develop behind the ridge with
increasing middle and high level moisture. Cloudiness will
continue to increase through tonight and into Monday as the air
mass moistens. A trough of low pressure continues to spin near 24N
and 130W, or about 1000 miles southwest of Los Angeles, while
another trough sharpens near 40N and 140W, or about 1300 miles to
the northwest of Los Angeles. These troughs will interact with
each other over the next 24 hours to bring a change in the weather
pattern for early this week. A moist subtropical mass will start
to stream over the area on Monday as the trough to the southwest
moves northeast into the region. The trough to the southwest will
get absorbed into the trough to the northwest. A warm frontal
boundary will develop and move over the area on Monday. Light to
occasionally moderate precipitation will occur through Monday
afternoon, then the system's cold front will move into the region
on Monday night.

Strong and potentially damaging southerly winds will develop
ahead of the cold front as models continues to bring 40 knot
winds at 950 mb and 50-55 knots at 850 mb. The timing for the
strongest winds will develop between Monday afternoon and Monday
night, lingering into Tuesday. High wind watches for portions of
San Luis Obispo and Santa Barbara Counties were converted to High
Wind Warnings. A watch remains for the Antelope Valley and was
added for the Santa Monica Mountains.

A Winter Storm Warning was converted from a Winter Storm Watch for
the Los Angeles and Ventura County mountains as strong and
potentially damaging southerly winds will develop ahead of and
along the cold front with moderate to heavy snowfall likely
developing along and behind the cold front. Generally,
snowfall amounts are forecast to be between 8 to 18 inches above
8000 feet, with between 3 and 6 inches falling between 6000 to
8000 feet. Isolated amounts up to 24 inches cannot be ruled out
for this storm.

Rainfall amounts have been increased some to between 2 and 4
inches for the coastal and valley areas to 4 to 6 inches in the
foothills and mountains. Isolated amounts up to 7 inches are
possible along south and southwest facing slopes. Amounts will be
much less in the Antelope Valley between 1 inch to 1.50 inches.

Rainfall will be heavy at times on Monday night and Tuesday,
especially across portions of Los Angeles, Ventura, and Santa
Barbara Counties. Peak rainfall rates still look range between
0.50 to 1.00 inch per hour thresholds. These thresholds could be
locally exceeded beneath any thunderstorms that develop. A Flash
Flood Watch remains in effect between late Monday afternoon
through Tuesday evening. While much of the focus has been placed
on the potential for flash flooding and debris flows near burn
areas, which is of greatest concern, some concern also needs to be
placed for urban flooding and roadway flooding. Rainfall rates
such as these will be sufficient enough to produce urban and
roadway flooding. The Flash Flood Watch may be expanded to include
this idea later today.

A showery weather pattern with a potential for heavy rainfall will
linger into Tuesday evening, then the air mass will start to
stabilize and dry out into Wednesday. Gusty post-frontal winds
will likely linger through Thursday, especially through the
Interstate 5 Corridor and across Southern Santa Barbara County.

.LONG TERM...(THU-SUN)

The flow pattern should turn offshore on Thursday. High pressure
building into the region should allow for warmer and drier
conditions through the weekend. Winds could approach advisory
levels at times, especially Thursday into Friday, but look to
weaken through weekend.

&&

.AVIATION...

08/0035Z

At 2330Z, at KLAX, there was a weak marine inversion of 500 feet.
The top of the inversion was 1200 feet with a temperature of 19
degrees Celsius.

Low confidence in 00Z TAFs due to uncertainty in timing and height
of developing low cigs/vsbys and timing of rain ahead of
approaching significant storm system. There is a 30 percent chance
of IFR to LIFR cigs/vsbys at KSMX, KSBP, and KOXR between 02 and
10Z. Timing of rain could be off by +/- 3 hours. Brief IFR to
LIFR cigs/vsbys are possible in heavier showers. Weak to moderate
LLWS due to increasing southerly winds is expected beginning
between 18Z and 00Z at KSBP and KPRB and after 21Z for KSMX.

KLAX...Low confidence in 00Z TAF. There is a 50 percent chance of
easterly winds increasing to 10 knots or greater between 14Z and
18Z. Brief IFR to LIFR cigs/vsbys are possible in heavier
showers.

KBUR...Low confidence in 00Z TAF. Brief IFR to LIFR cigs/vsbys
are possible in heavier showers.

&&

.MARINE...

07/100 PM

For the Outer Waters, good confidence in current forecast.
Southeast winds will increase Monday and Monday night and are
expected to reach Gale force levels (35-40 knots). So, a GALE
WARNING has been issued from Monday afternoon through Monday
night. On Tuesday, the winds will shift to the west and northwest
behind the front and decrease in speeds. However, there is a 70%
chance of Small Craft Advisory (SCA) level winds continuing
Tuesday through Friday.

For the Inner Waters, good confidence in current forecast. For the
waters north of Point Sal, southeast winds will increase to Gale
force levels Monday afternoon through Monday night and a GALE
WARNING has been issued. On Tuesday, the winds will shift to the
west and northwest and remain west to northwest through Friday
with a 40% chance of SCA level winds Tuesday through Friday. For
the waters south of Point Conception, Gale force winds are
expected across the western half of the SBA Channel Monday
afternoon through Monday night and a GALE WARNING has been issued.
Elsewhere, southeast winds are expected to increase to strong SCA
levels Monday afternoon through Monday night. On Tuesday, the
winds will shift to the southwest and west and remain at SCA
levels. For Wednesday through Friday, winds are expected to remain
below SCA levels.

There will be isolated thunderstorms across the coastal waters
with a threat of weak waterspouts from Monday evening through
Tuesday afternoon. Read the latest Marine Weather Statement for
more details.

A large westerly swell will move across the coastal waters
Tuesday and Wednesday.
