AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
523 PM PDT MON JUN 13 2016

...UPDATE FOR NEW AVIATION DISCUSSION...

.SYNOPSIS...

Night through morning low clouds will shrink in coverage through
midweek as an upper level low moves east. A broad trough of low
pressure will then develop off the northern California coast,
resulting in continued mild temperatures through Thursday. High
pressure expanding west from the four corners region may produce a
significant heat wave for the weekend into early next week.

&&

.SHORT TERM...(TDY-THU)

The shortwave trough that gave us cooler temperatures over the
weekend is pushing east today and allowing some height rises and
warming behind it. Temperatures have warmed today across inland
areas a good 5 to 15 degrees over yesterday's highs while still
well below normal. Complicated overnight stratus pattern within
the 3000 ft marine layer but most areas have cleared out through
the morning and early afternoon. Only stubborn clouds have hung
on over the San Gabriel Valley and the SBA County south coast
foothills. Not a lot of changes in store for Tuesday other than
the marine layer shrinks to around 1500 feet with what's expected
to be a normal overnight stratus pattern that should clear to or
just past the beaches in the afternoon. Temperatures will be
pretty close to today's highs and remaining

The broad upper trough currently just off the Pac NW sags south
just enough on Wednesday to lower our heights, bring a slight
bump up in marine layer depth, and cool high temps inland areas.
Trough doesn't move much on Thursday so expect relatively similar
conditions on Thursday. Overnight coastal stratus coverage will be
similar both nights.

Not much happening wind-wise other than potential sundowners
Tuesday and Wednesday evenings and nights plus the usual afternoon
gusty westerly winds Antelope Valley.

.LONG TERM...(FRI-MON)

The primary weather event of this forecast remains the potential
for excessive heat Sunday and Monday when a very strong upper
level high builds in over the desert southwest. The high appears
to peak on Monday when the GFS forecasts a 500 mb height center of
601 dm just south of the four corners.

The warmup here starts on Friday and continues into Saturday when
high temps warm 5 to 10 degrees each day. Models have been
consistent in forecasting the warmest days on Sunday and Monday.
GFS 1000-500 mb thickness values of 582 dm are forecast over
downtown L.A. for Sunday 12z. They increase to 587 dm by Monday
12z. With this will be weak offshore pressure gradients (-0.5 LAX-
DAG both Sunday 12z and Monday 12z). Prior to September 27, 2010
when Downtown L.A. (CQT) reached its all-time high of 113, its
next highest high temp was on June 26, 1990 when the high
temperature at CQT reached 112. For the June 1990 event, the LAX-
DAG gradient was 0 mb while the 1000-500 mb thickness was 581 dm.
So similar if not more intense conditions for this upcoming heat
event. High temps in the valleys will likely reach into the 100's
and those numbers may even stretch into some coastal areas. Highs
in the Antelope valley will likely reach near 110 by Monday.

Relative humidities will be low to at least allow overnight
temperatures to drop below 70 Sunday and Monday night.

.AVIATION...14/0010Z...

At 2310Z...the marine inversion at KLAX was at 2600 ft deep. The top
of the inversion was at 4800 ft with a temperature of 17 deg C.

Generally hi confidence in the 00Z TAFs. Low clouds and LIFR/IFR/
MVFR cigs will affect the coastal and vly airfields during the TAF
fcst period, with the onset of low clouds ranging from TAF issuance
time at KOXR and KLAX to 12Z at KPRB. For those airfields where the
low clouds will move in this evening or later tonight, the onset of
the clouds may be off +/- an hour or two. The low clouds will clear
to VFR at all these airfields from late Tue morning to early Tue
afternoon, except should persist thru the day at KOXR. For KPMD and
KWJF, VFR conditions will continue thru Tue afternoon with gusty sw
afternoon and evening winds persisting.

KLAX...Generally hi confidence in the 00Z TAF. Low clouds and MVFR
cigs will prevail from TAF issuance time to about 21Z Tue, altho
there is a 20 percent chance intermittent MVFR cigs could prevail
thru Tue afternoon. The low clouds with MVFR cigs then should move
back into the airfield around 03Z Tue evening.

KBUR...Generally hi confidence in the 00Z TAF. Low clouds and MVFR
cigs will develop around 08Z then continue thru around 19Z Tue. The
timing of the onset of low clouds tonight may be off +/-an hour or
so. Otherwise, VFR conditions can be expected thru Tue afternoon.

&&

.MARINE...13/200 PM PDT.

Good confidence in SCA conditions developing across the northern
two thirds of the outer waters and the inner waters north of Pt
Conception this afternoon, with SCA condition spreading into the
southern waters this evening. Expect SCA conds to continue across
the outer waters through at least Wed night. Across the northern
inner waters SCA conditions will likely end late tonight, then
develop again during the afternoon and evening hours Tue and Wed.
There is a 20 percent chance of SCA level winds across western
portions of the SBA Channel late this afternoon and evening, and
a 30 to 40 percent chance of SCA conds during the late afternoon
and evening hours Tue and Wed.

Due to storms in the South Pacific, there will be some increase
in swell from 190-220 degrees later this week.
