Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
512 AM PST Fri Jan 19 2018
.SYNOPSIS...
An incoming storm system will bring much cooler temperatures...
gusty winds...light rain and mountain snow showers to the region
today. Snow showers will linger into Saturday morning across the
northern slopes. Hazardous driving conditions expected across the
Interstate 5 Corridor around the Grapevine this evening through
Saturday morning. Warmer conditions return next week with a
slight chance of showers primarily along the Central Coast early
next week.
&&
.SHORT TERM...(TDY-SUN)
Latest satellite imagery indicated plenty of high to mid level
clouds moving across the forecast as a weakening frontal boundary
moves into SLO county this morning. Below the high clouds plenty
of low clouds were filling across LA/VTU Counties W of the
mountains. There will be a chance of some morning drizzle across
portions of LA/VTU Counties early this morning, while light
showers continue to move across areas N of Point Conception this
morning. As the upper trough continues to move rather quickly
through the area, the lower level wind profiles will not be
conducive for much in the way of precip across areas S of Point
Conception, especially Ventura County and the SBA South Coast due
to the downsloping from the mountains upstream. There will be a
better chance of precip across southern L.A. County towards the
valleys and foothills later this afternoon and overnight hours.
Have tailed back the slight chance for thunderstorms this evening
to only the northern portion of the outer waters. Most of the
precip will be concentrated across the northern slopes of the
Ventura County Mountains and NW northern slopes of the L.A. Mtns
including the I-5 corridor around the Grapevine. Snow levels will
remain high this morning between 7500 to 8000 ft, but by late this
afternoon or early evening, snow levels are expected to plummet
to around 4000 ft. then lowering to between 2500 and 3500 ft after
midnight tonight. With most of the moisture being concentrated
across the northern slopes of the LA/VTU county mtns, travel
across the I-5 Corridor is expected to be treacherous due to
blowing snow and icy conditions. NW to N winds are expected to
strengthen late this afternoon through Saturday morning across the
mountains.
A Winter Weather Advisory is in effect for the LA/VTU/SBA County
Mountains beginning late this morning including the foothills of
the Cuyama Valley. The timing might be a tad early, but snow
levels will lower to around 6000 ft by this afternoon. Expect 3-6
inches of snow with highest amounts across the nrn slopes. Also an
inch of snow for the Cuyama Valley foothills. Wind gusts of 50
mph can be expected later this evening to go along with the snow.
A wind advisory will be issued for the SBA South Coast from late
this afternoon through mid morning Saturday. Winds are expected to
get gusty across the Montecito area late tonight into Saturday
morning as well. The day shift might have to add wind advisories
for the Santa Clarita/San Fernando Valleys and possibly for the LA
Basin, especially the western L.A. tonight into early Saturday.
For Saturday there could be a few lingering showers across
Southern L.A. County including the eastern San Gabriel Mtns as
well as the northern slopes of the local mountains, especially
the Ventura County Mtns. Snow showers should linger into early
Saturday afternoon across the I-5 corridor, then diminish. Expect
partly to mostly cloudy skies across the interior areas Saturday,
with partly cloudy skies for most other areas. There will be the
slightest warming trend on Sunday, but still remain a bit cooler
than normal for this time of year. Skies should remain partly
cloudy on Sunday, but that could be a bit pessimistic for coastal
areas which could see more sunshine.
.LONG TERM...(MON-THU)
Slow warming trend early next week as a weak ridge starts to
build over the area. Both the GFS and ECMWF show the tail end of
another weak front coming through the area Monday but any
precipitation should be confined to nrn SLO County before it
completely washes out. Elsewhere just some mid and high clouds
which should keep partly cloudy skies for the most part through
Wednesday. By Thursday, clouds should be on the increase. Models
still in poor agreement late next week with the possibility of
another weak system for Thu but again very low confidence. None of
the model solutions in the last few days have indicated anything
more than a very light precip event at best, and mostly northern
areas. Then dry and warmer going into next weekend.

.AVIATION...19/12Z...
At 1130Z, the marine layer at KLAX was 1000 ft deep. The top of
the inversion was near 2400 ft with a temperature of 16 deg C.
Very chaotic cloud pattern across the region early this morning,
with widespread cigs at several different levels. For the most
part, conds were IFR to LIFR west of the mountains, with local
VLIFR conds. Conds should become mostly MVFR in most areas by late
morning, although IFR to LIFR conds will likely cont in the
foothills and mtns. There will be a few showers this morning.
Cigs will likely scatter out in coastal sections this afternoon,
especially from VTU County northward. Conds should be mostly VFR
tonight, except LIFR conds will likely continue on northern
slopes, with clouds and snow showers.
Gusty NW winds will affect the Central Coast this afternoon and
the I-5 corridor this morning thru Sat morning. Gusty NW to N winds
will affect the south coast of SBA County this afternoon thru Sat
morning, many coastal and valley areas of Los Angeles County this
evening thru Sat morning, and the Antelope Valley this evening
thru Sat evening. There will be areas of LLWS and moderate UDDF.
KLAX...Low confidence in the 12Z TAF. There will likely be rapid
changes in cig heights and vsbys this morning. Expect conds to
become MVFR by 16Z but there is a 20% chance that IFR conds could
persist through 18Z. There is a 30% chance that MVFR conds could
affect the airport thru late tonight. There is a 20-30% chance
that northerly cross winds will gust to 20 kt or greater between
06Z and 18Z Fri with LLWS possible.
KBUR...Low confidence in the 12Z TAF. There will likely be rapid
changes in cig heights and vsbys this morning. Expect conds to
become MVFR by 16Z but there is a 20% chance that IFR conds could
persist through 18Z. There is a 30% chance that MVFR conds could
affect the airport thru late tonight. There is a 20-30% chance
that northwest to north winds will gust to 20 kt or greater
between 06Z and 12Z Fri with LLWS possible.
&&
.MARINE...19/430 AM...
For the Outer Waters, moderate to high confidence in current
forecast.
Across the southern two outer waters zones (PZZ673, PZZ676),
a Gale Warning is in effect thru Sat evening. There is a 20%
chance that winds will remain below gale force there.
Across the northern zone (PZZ670), SCA conds are expected thru
Sat night. There is a 20% chance that winds will reach gale force
across the northern zone (PZZ670) thru Sat.
For the inner waters north of Point Sal, moderate to high confidence
in the current forecast with SCA conds thru Sat night. There is a
20% chance of gale force winds this afternoon thru Sat evening.
Across the SBA Channel and the southern inner Waters, moderate to
high confidence in the forecast, with SCA conds through early
this afternoon, then gale force winds from mid afternoon today
through Sat evening. There is a 20% chance that winds will remain
below gale force through Sat.
Very large NW swell will affect all waters today and tonight,
then swell will slowly subside Sat and Sat night. Dangerous
breaking waves are possible near harbor entrances, including
Morro Beach Harbor and Ventura Harbor through Saturday
&&
.BEACHES...19/500 AM...
An extended period of large surf is expected to continue along
west to northwest facing beaches through Saturday evening as very
large westerly swells move through the coastal waters.
For west and northwest facing beaches along the Central Coast,
surf will average 15 to 20 feet with local sets to 25 feet today,
then surf will slowly subside tonight through Saturday evening. A
HIGH SURF WARNING remains in effect from this through 900 PM PST
Saturday. The high surf may cause beach erosion and will produce
life-threatening rip currents. Minor coastal flooding is possible
in low lying areas such as parking lots, especially near the times
of high tide, especially late this morning.
For west and northwest facing beaches south of Point Conception,
surf will average 8 to 12 feet today into tonight. Local sets to
15 feet are possible on exposed west facing locations such as
Ventura Harbor. High surf will slowly subside Saturday and
Saturday evening. A HIGH SURF ADVISORY remains in effect through
900 PM PST Saturday evening.
