AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
447 PM PDT WED JUN 29 2016

.SYNOPSIS...

A slight chance of thunderstorms and showers in the San Gabriel
mountains into this evening. Breezy winds for Santa Barbara...
Ventura and Los Angeles mountains and deserts into Thursday. Above
normal temperatures and the overnight marine layer will persist into
next week. The increasing onshore flow will spread the marine layer
and bring a cool down for this weekend. The high should roll back
in by Monday for a gradual warmup for next week.

&&

.SHORT TERM...(TDY-SAT)

Elevated instability indexes combined with relatively high
residual moisture led to adding a slight chance of thunderstorms
to the San Gabriel Mountains for late this afternoon and evening.
A few cumulus have popped up over the area already though the best
timing for the instability will be closer to 5 pm. Am not
expecting much precipitation to develop but a lightning strike or
two along with gusty winds could be a problem so is something to
watch.

Northwest to northerly winds will be gusty through the mountains
and across the south coast of Santa Barbara County tonight. Winds
will shift to the northeast late then diminish.

Afternoon temperatures are a mixed bag today with some coastal and
adjacent valley locations a few degrees warmer than yesterday and
some a few degrees cooler. Sunny skies but a stronger onshore flow
are the primary competing weather forces in the tug of war and the
continued higher than normal humidity has added to the
sluggishness of either a warmer or cooler trend. Regardless...
temperatures are in the forecast ball park and the trend from
today will be cooler and drier into the weekend.

Helping that cooling trend along will be a strengthening onshore
flow. It will continue to strengthen through the end of the week
and the marine incursion will likely make it into the adjacent
valleys by Friday morning if not for a period on Thursday.

&&

.SHORT TERM...(TDY-SAT)

.LONG TERM...(SUN-WED)

Afternoon temperatures will bottom out on Saturday and Sunday as a
relatively strong onshore flow brings the marine incursion into
the coastal adjacent valleys and the cloud cover lingers well into
the morning. What happens next remains a bit uncertain - in
particular whether temperatures trend warmer slowly or quickly.
The current forecast package trends slowly but definitely warmer.
There remains a hint of further cooling instead but that would be
a happy turn of events if it occurs.

The monsoonal moisture does not retreat very far to the east and
looks to remain close to the California / Arizona border for at
least the next week. Therefore humidity levels should be slightly
higher for the period with a possibility of a return to stickiness
of the pattern shifts much.

&&

.AVIATION...29/2345Z...

At 2300Z, at KLAX, the marine layer depth was 1200 feet. The top
of the inversion was at 2900 feet with a temperature of 29 degrees
Celsius.

With a shallow marine layer topped by a strong inversion, clearing
has been difficult for portions of the immediate coast this
afternoon. High confidence in 00z TAFS with ifr/lifr cigs
returning to most coastal TAF locations tonight. With a slight
deepening of the marine layer expected, look for some vsby
restrictions into some of the coastal valleys on Thursday
morning, including KBUR and KVNY. Otherwise, moderate uddfs
and llws expected this evening vcnty KSBA due to sundowner winds
in the nearby foothills.

KLAX...High confidence in 00Z TAF. IFR cigs expected to return
this evening, and persist into early Thursday morning. There is a
30 percent chance of marine clouds returning plus or minus two
hours or more from time in forecast.

KBUR...Moderate confidence in 00Z TAF. Mostly VFR conditions
through period, except MVFR vsbys in haze on Thursday morning.
There is a 20 percent chance of LIFR/IFR cigs sneaking into the
airfield early Thursday morning.

&&

.MARINE...29/200 PM...

For the Outer Waters, good confidence in the current forecast. SCA
level winds will continue through tonight. From Thursday through
the weekend, the northwest winds will be a bit weaker, but there
will still be a 30 percent chance of SCA level winds developing
each afternoon and evening.

For the Inner Waters, good confidence in the current forecast.
Overall, winds and seas are expected to remain below SCA levels
through the weekend. However, there is a slight chance of gusts
reaching SCA levels this afternoon/evening across the waters north
of Point Sal.

Patchy dense fog in the coastal waters will be possible in the
overnight and morning hours tonight and again Wednesday night.
