AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
551 PM PDT MON MAY 30 2016

.SYNOPSIS...

There will continue to be overnight and morning low clouds and
fog, especially at the beaches through the period. A ridge will
build in Tuesday through Thursday, bringing well above normal
temperatures to the valleys and interior. Another cutoff low is
expected by the weekend, lowering temperatures a few degrees.
&&

.SHORT TERM...(TDY-WED)

A few cumulus clouds are building over the Mountains and the
Antelope Valley this afternoon as a trough of low pressure over
Southern Arizona slowly exits the region.

The main weather issue is the clouds hanging along the California
coast. The latest visible satellite imagery shows stratus hanging
tough along the coast this afternoon. KLAX AMDAR soundings
indicates a marine layer depth around 3500 feet deep with a
strong marine inversion above. The marine layer depth will thin
as an Omega Block ridge of high pressure over the Eastern Pacific
Ocean builds in through Thursday. By Tuesday morning, the marine
layer will likely thin to around 1700 feet deep, then thin
additionally on Wednesday and Thursday. With the ridge building
in, the marine inversion will tighten through Thursday. May Gray
into June Gloom will be the scenario. Marine layer stratus will
continue to sock in the beaches throughout much of the week.
Outside of the marine influence, the air mass will warm as
subsiding air aloft creates compressional heating. Away from the
coast, daytime temperatures will warm to well above normal levels
by Wednesday. Overnight lows may only cool to the upper 60s and
70s in the foothills. Some locations in the Antelope Valley may
hit the century mark, especially Wednesday and Thursday.

.LONG TERM...(THU-SUN)

After minimal marine layer stratus coverage on Friday morning,
ridging aloft will slowly start to push east on Friday and allow
for a trough of low pressure over the Central Pacific Ocean to
brush the area. Increasing onshore flow should provide a cooling
trend into late week along with a more developed and deeper marine
layer. Showers and Thunderstorms cannot be ruled out across the
area, especially for the Mountains and Desert and areas North of
Point Conception where the best instability is progged to be by
both the ECMWF and GEFS solutions.

&&

.AVIATION...
31/0040z.

At 0015Z at KLAX...the marine layer was about 2700 feet deep. The
top of the marine inversion was near 4600 feet with a temperature
of 23 degrees Celsius.
Will continue with persistence forecast for the next 24 hours,
except with onshore gradients trending weaker over the next 24
hours, there will be a 40 percent chance that cigs could scour out
earlier across valleys with continued stratus lingering across
most coastal areas through much of tomorrow. for areas n of Point
Conception,expect LIFR/IFR conds through tomorrow morning. S of
Point Conception, expecting mostly MVFR conds but 60 percent
chance that some IFR cigs will develop overnight for some valley
tafs. there is a chance for some llws near ksba for a few hours
this evening.

KLAX...There is moderate confidence in the 00Z TAF. MVFR to
isolated IFR conditions are expected tonight into Tuesday morning.
There is a 30 percent chance of marine clouds arriving plus or
minus two hours from forecasted times.

KBUR...There is low to moderate confidence in the 00Z TAF. The
greatest uncertainty in this forecast is in regards to whether the
marine clouds will make it into the airfield tonight. There is a
40 percent chance of VFR conditions through the night.

&&

.MARINE...30/200 pM...

Conditions will likely remain below advisory levels through at
least Friday. The northwest swell across the coastal waters will
diminish through the middle of the week. A long period south swell
is expected to reach the coastal waters tomorrow then peak on
Wednesday and Thursday before subsiding. The swells will likely
remain below advisory criteria but there will be extra surging and
currents along exposed south facing shores.
