UPDATED AVIATION SECTION

.SYNOPSIS...06/311 AM.

Temperatures will cool today and Tuesday with increasing onshore
flow and areas of low clouds and fog near the coast. Warmer
temperatures will return briefly Wednesday before a sustained
cooling trend takes us into the weekend with a chance of rain.

&&

.SHORT TERM (TDY-WED)...06/759 AM.

Weak upper level trough moving into region today, bringing
increased onshore flow and a cooling trend, most noticeable
across coastal and coastal valley areas. There is a return of
marine layer influence across coastal areas this morning, with
ACARS sounding showing marine layer depth around 1000 feet
across the LA Basin. Low clouds and fog have been erratic
this morning across coastal areas due to considerable higher
level clouds streaming over the area. The bulk of the high level
clouds are expected to shift south of the forecast area by later
today. Most coast and valleys will drop at least 3-6 degrees from
yesterday`s highs and near the beaches the drop could be as much
as 10 degrees.

Onshore pressure gradient are increasing this morning and will
further increase across the region this afternoon, when LAX-
Daggett pressure gradient could reach +5 to +6 mb range. This
will generate increasing onshore winds across the interior this
afternoon/evening, and this trend will continue the next few days.
Also expecting northwest pressure gradients to increase tonight
and the next few nights, with Santa Barbara-Santa Maria expected
to reach around -4 mb. A wind advisory has already been posted for
later today into tonight for the western Santa Ynez mountains and
southwest Santa Barbara coast, with gusts in the 35 to 50 mph
range. Winds will be strongest tonight from Gaviota to San Marcos
Pass. A wind advisory may need to be expanded to include the I-5
corridor and western Antelope Valley foothills as early as
tonight, with increasing probability for Tuesday night. In
addition, the sundowner winds are expected to shift eastward into
the eastern Santa Ynez range by Tuesday night, which may require
wind advisories for that region as well. North gradients will peak
Wednesday, and with an increase in support aloft and subsequent
downsloping south of the mountains, temperatures are expected to
rise anywhere from 3 to 6 degrees, making Wednesday the warmest
day of this week.

.LONG TERM (THU-SUN)...06/419 AM.

A rapid cooling trend will begin Thursday and continue at least
through next weekend as the upper low currently near 35n/140w
moves into central and southern California. There`s still a
pretty big spread in the rain amounts and timing, but chances for
at least some rain between Friday and Sunday are over 80%
everywhere in the southwest California region. There`s quite a few
solutions from both the AI and non-AI models indicating over a
half inch of rain with even about a 30% chance of an inch or more.

.AVIATION...06/1808Z.

At 1634Z at KLAX, the marine layer was 1200 ft deep. The top of
the inversion was at 1900 ft with a temperature of 18 C.

Overall, moderate confidence in 18Z TAF Package. Timing of
CIG/VSBY restrictions may be off +/- 2 hours and flight minimums
by one category. More confident in CIGs tonight due to less high
clouds and the development of a weak to moderate Catalina eddy
overnight. With this LIFR CIGs could possibly arrive (40% chance)
at KBUR & KVNY between 07/10Z-16Z.

KLAX...Moderate confidence in TAF. Arrival and clearing times of
CIGs may be off +/- 2 hours. CIGs likely to range from IFR to
low-end MVFR 007-015. No significant east wind component is
expected.

KBUR...Moderate confidence in TAF. LIFR CIGs possible (40% chance)
between 07/10Z-16Z.

&&

.MARINE...06/750 AM.

Small Craft Advisory (SCA) level winds will become widespread by
this afternoon to include all Outer Waters, nearshore along the
Central Coast, and the Santa Barbara Channel. SCA winds will
continue across all Outer Waters through Wednesday. Winds will
diminish later in the week with moderate chances for SCA winds
lingering south of Point Conception on Thursday and Friday.

The Inner Waters will reach SCA levels at times mainly during the
afternoon and evening hours - lower chances along the Central
Coast later in the week. There is a 30% chance of GALE force winds
Wednesday night across the Santa Barbara Channel and near the
Channel Islands.

A storm system is expected to impact the coastal waters sometime
Thursday into the weekend bringing rainfall and the potential for
thunderstorms. Confidence is low on exact timing and details for
now.
