AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
404 AM PDT FRI JUN 10 2016

.SYNOPSIS...

Southwest flow aloft will develop ahead of a trough of low
pressure off the California coast. Strengthening onshore flow and
a deeper marine layer will bring cooling and expand stratus
coverage into the coastal slopes of the mountains into early next
week. A warming trend should develop late next week as a ridge of
high pressure expands westward.

&&

.SHORT TERM...(TDY-SUN)

The latest water vapor imagery indicates a trough of low pressure
about 500 miles southwest of Los Angeles early this morning.
Another trough of low pressure is situated off the British
Columbia Coast near 48N and 130N.

Strengthening southwest flow aloft ahead of the trough to the
southwest will bring a deeper marine layer through the weekend as
onshore flow strengthens. Onshore pressure gradients are slightly
stronger onshore early this morning. A developing middle and high
level cloud mass on leading edge of the trough circulation will
bring mainly partly cloudy skies today through Saturday over most
of the area. The latest AMDAR soundings from KLAX indicate a
marine layer depth near 2100 feet deep this morning, which is
close to what the latest NAM BUFR time height sections suggest.
The marine layer depth should continue to deepen to around 3000
feet later this morning, then deepen additionally to near 3500 to
4000 feet into Saturday and Sunday mornings. What this all boils
down to is a cooling and moistening trend across the area for the
weekend.

The trough circulation will lift into the region by Saturday night
then the trough to the northwest will drop in behind it on Sunday
and into Monday. Instability with the trough could bring some
clouds over the Los Angeles and Ventura County Mountains this
afternoon and evening, but any precipitation should stay east and
south of the area. A better chance of isolated showers and
thunderstorms is possible for mountains and maybe the desert over
the weekend as the troughs draw closer to the area. Patchy night
through morning drizzle could develop across the South Coast Basin
tonight through Saturday morning, and possibly again on Saturday
night and into Sunday morning.

.LONG TERM...(MON-THU)

A deep marine layer will remain in place through Monday, but the
marine layer depth should start to thin. Southwest flow aloft
will keep some semblance of a marine intrusion in place for most
of next week, but a ridge of high pressure over the Texas
Panhandle this morning will reposition over the Sonoran Desert and
strengthen for the latter half of next week. This high pressure
system will slowly start to creep westward by late next week. 500
mb heights should start climbing each day and thin the marine
layer for late next week. Warmer conditions will develop for the
latter half of next week, especially away from the coast.

&&

.AVIATION...10/1100Z...

At 1050Z, the marine inversion was based at 2100 feet. The top of
the inversion was 3900 feet with a temperature of 20 degrees
Celsius.

Overall, moderate confidence in 12Z TAF package. Stratus firmly
entrenched across the coastal plain and valleys this morning with
MVFR/IFR cigs reported. Stratus should dissipate by early
afternoon, but will return tonight with a deeper marine inversion.

KLAX...moderate confidence in 12Z TAF. There is a 30% chance that
MVFR cigs will not scatter out this afternoon. For tonight, high
confidence in return of MVFR level stratus, but low confidence in
timing.

KBUR...moderate confidence in 12Z TAF. IFR cigs could dissipate
+/- 1 hour of current 17Z forecast. For tonight, high confidence
in return of MVFR cigs, but low confidence in timing.
&&

.MARINE...10/200 AM...

For the Outer Waters, good confidence in current forecast. High
confidence in Small Craft Advisory (SCA) level winds continuing
through Saturday (with a 20% chance of gale force gusts). For
Sunday, winds will drop off below SCA levels. However on Monday
and Tuesday, the northwest winds will increase with SCA level
winds likely and a 20% chance of gale force gusts.

For the Inner Waters, good confidence in current forecast. For the
waters north of Point Sal, expect northwest winds to increase to
SCA levels this afternoon/evening. Winds will then decrease below
SCA thresholds through Monday then possibly increase to SCA levels
on Tuesday. For the waters south of Point Conception, winds and
seas are expected to remain below SCA levels through Tuesday
although there is a chance of some SCA level gusts Tuesday
afternoon across the western half of the Santa Barbara Channel.
