AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
449 AM PDT Thu Jul 20 2017

.SYNOPSIS...
An upper level ridge of high pressure will persist over the area
through the weekend. There will be areas of night through morning
low clouds and fog in most coastal and some valley areas. Temperatures
will be near or slightly above normal today, then rise a bit
through Saturday. Some cooling is expected Sunday into early next
week. Monsoonal moisture may bring some showers and thunderstorms
to the mountains and Antelope Valley Monday through Wednesday.

&&

.SHORT TERM...(TDY-SAT)

Low clouds were widespread on the Central Coast and in the
Santa Ynez Valley early this morning. South of Pt Conception,
clouds were patchy in nature and confined to coastal sections of
L.A. and VTU Counties. During the past hour or two, clouds have
become more organized, and expect widespread low clouds and fog
in coastal sections of L.A. and VTU Counties by daybreak. At 1100
feet, the marine layer is deep enough to allow low clouds to push
into the San Gabriel Valley and portions of the VTU County
valleys. N-S offshore gradients across SBA were weakening, so some
clouds may push into the south coast of SBA County as well. Any
low clouds in the valleys should clear by mid morning, and during
late morning across the coastal plain. Some high clouds in the
Antelope Valley and the L.A. County mountains may drift across the
remainder of L.A. County this morning. There were just some
buildups in the mtns Wed afternoon, with convection remaining just
east of the region. With less in the way of moisture and
instability, would be surprised if there is anything more than
some buildups today. With little change in heights/thicknesses or
temps at 850/950 mb, expect max temps today to be similar to those
on Wed, generally not far from normal in most areas.

An upper high extending from Wyoming southwestward into CA will
move little through Sat. However, it is forecast to strengthen a
bit. This should cause the marine layer to become a bit more
shallow each day. Expect less in the way of night through morning
low clouds and fog in the valleys tonight and Fri morning, with
clouds likely limited to the coastal plain Fri night and Sat
morning. Max temps should be up a few degrees in most areas Fri,
then maybe a degree or two more on Sat.

Offshore N-S gradients across SBA County will likely be strong
enough to cause some gusty NW to N winds across the Santa Ynez
Range and adjacent south coast of SBA County this evening, and
again Fri evening, but expect winds to remain just below advisory
levels. However, the N-S gradients may be sufficiently strong to
keep skies clear on the south coast of SBA County tonight and Fri
night.

.LONG TERM...(SUN-WED)

A weak upper low moving through the eastern Pacific will be
located off the coast of northern CA Sunday. The marine layer may
deepen a bit Sat night, but do not expect too much change in
night thru morning low cloud coverage Sat night/Sun morning, with
clouds confined mainly to the coast. However, there should be a
bit of cooling Sunday, mainly west of the mountains.

The upper low will move into northern CA and weaken on Monday,
then a broad trough will linger to the north of the region through
Wed. Heights and thicknesses across the region will fall Mon. The
marine layer will deepen, with night through morning low clouds
likely pushing into at least the lower valley location. Max temps
will likely be down a few degrees on Mon, down to slightly below
normal levels in most areas. The 00Z run of the GFS showed
increasing monsoonal moisture across the region Mon, enough for at
least a slight chance of afternoon and evening showers and
thunderstorms in the L.A. and VTU County mountains and the
Antelope Valley. Then, it showed monsoonal moisture extending
farther to the northwest Tue and Wed, with a slight chance of
tstms extending into the mtns of SBA County, the Cuyama Valley
and sern SLO County by Wed. The 06Z run of the GFS has trended
drier, especially for Wed, so those pops may have to be adjusted
by later shifts.

.AVIATION...20/1030Z

At 1000Z, the marine inversion at KLAX was around 900 ft deep.
The top of the inversion was at 3700 ft with a temperature of 23
deg C.

N of Point Conception...Moderate confidence with coastal IFR TAFs
30% chance for LIFR conds between 12z-15z this morning. Higher
confidence with scour out times within +/- 2 hours of 12Z TAF.
Moderate confidence with timing of IFR cigs this evening through
Friday morning.

S of Point Conception...Low confidence with areal coverage and
timing of MVFR/IFR cigs. Stratus should scour out within 2 hours
of 12Z TAFs. Otherwise there is generally hi confidence in the
12Z TAFs at KBUR, KVNY, KWJF and KPMD with VFR conditions expected
thru tonight, altho there is a 30 percent chance of MVFR cigs
developing at KBUR late tonight into early Thu morning. Gusty sw
to w afternoon and evening winds will persist at KWJF and KPMD.

KLAX...Low confidence overall in the 12Z TAF due to uncertainties
in the timing of low clouds and IFR/MVFR conditions through this
morning. Low clouds and MVFR cigs should move back in around 04Z
this evening. The timing of the onset and dissipation of the low
clouds may be off +/- 1 to 2 hours or so.

KBUR...Generally hi confidence in the 12Z TAF with VFR conditions
expected for the most part thru Fri morning. A period of MVFR
vsbys will be possible 12Z-16Z or so.

&&

.MARINE...20/300 AM...

For the Outer Waters, high confidence that small craft advisory
winds will continue through at least Friday night, and potentially
through Sunday. There is a 20 percent chance of gale force winds
for zones 670 and 673 today/Friday afternoon/evening.

For the inner waters south of Point Conception, winds and seas
are expected to generally remain below SCA level through the
weekend.

&&

.LOX WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
PZ...Small Craft Advisory in effect until 3 AM PDT Saturday for
      zones 670-673-676. (See LAXMWWLOX).

&&

.HAZARD POTENTIAL OUTLOOK...(SAT-WED)
No significant hazards are expected during this period.
