.SYNOPSIS...13/757 PM.

A gradual warm up is expected Wednesday and Thursday with
lighter onshore winds as high pressure builds over the area. A
cooling trend with more marine influence is expected Friday
through the weekend.

&&

.SHORT TERM (TUE-FRI)...13/154 PM.

A couple of weak troughs will move through the region the
remainder of this week and then another over the weekend which
will keep temperatures below normal. However, onshore flow will
be weakening and heights rising following today`s trough passage
which will promote slight warming Wednesday and Thursday and less
afternoon wind. Marine layer stratus coverage is expected to
remain on the lower side, but like today there will likely be some
stratocumulus lingering into the afternoon, particularly in the
valleys.

Later Friday and Saturday a deeper trough is expected to arrive
along the West Coast. Cooler temperatures with a deeper and more
expansive marine layer coverage are the most likely outcomes of
this pattern. Saturday is expected to be the coolest day of this
stretch with highs mostly in the 60s area-wide. In addition, stratus
may linger through the afternoon with areas of drizzle possible in
the morning.

.LONG TERM (SAT-TUE)...13/217 PM.

There remains quite a bit of uncertainty beyond Saturday with
regard to the upper air pattern but most of ensemble solutions
keep some form of troughing along the West Coast at least through
Sunday. The deterministic models even maintain some cyclonic flow
aloft even into Monday. However, more than half of the ensemble
solutions favor a slightly faster progression towards ridging and
warmer temperatures. By Tuesday almost all areas are expected to
have above normal temperatures, with warmer valleys approaching
90. Onshore flow will be weakening as well leading to mostly light
winds across the area.

.AVIATION...14/0303Z.

Around 00Z at KLAX, there was no marine layer nor inversion.

High confidence in VFR conditions for KPMD, KSBA, KWJF, KVNY, and
KBUR. Low to moderate confidence elsewhere with a 20-50 MVFR to
IFR low cigs/vsbys between 07-16Z. End times of gusty conditions
may be off by 2-3 hours.

KLAX....Low to moderate confidence in TAF. There is a 20% chance
of BKN015 cigs from 11 to 15Z Wed. Good confidence in east wind
component remaining under 7 kts with only a 10 percent chance of
briefly reaching 7 kt sometime between 12-16Z.

KBUR...Moderate confidence in TAF due to winds. VFR conditions
expected.

&&

.MARINE...13/810 PM.

Winds are decreasing over the waters and Gales have been expired,
but Small Craft Advisory (SCA) winds will continue over the outer
waters through late Thursday night, and possibly(40-50% chance)
through the weekend. For the nearshore waters, SCA winds are
likely through late tonight, with a decrease early Wednesday. the
Central Coast waters and Santa Barbara Channel will see winds
increase to SCA levels again Wednesday afternoon and evening.
Steep seas will affect much of the waters but will gradually
decrease through late in the week.

SCA to Gale conditions will likely (60-80 percent chance) return
this coming weekend, with the highest confidence across the
northern and outer waters. Steep seas are expected to rebuild,
likely rising above 10 feet by Sunday.
