.SYNOPSIS...07/134 AM.

Night through morning low clouds and fog will continue for the
next several days over the coast and valleys with slow, if any,
clearing at the coast. A warming trend will develop for the
weekend and through next week, especially away from the beaches.

&&

.SHORT TERM (TDY-MON)...07/101 AM.

Quiet weather is on tap, as a moisture starved low pressure system
over the Bay Area will shift southwest a few hundred miles off the
Central Coast. This low pressure system will cause 500 mb heights
and thicknesses to rise over the area the next couple of days,
allowing high temperatures to warm 1-3 degrees each day
(especially for more inland areas). High temps are expected to
reach the low to mid 90s in the warmest valleys, while coastal
areas are in the upper 60s and 70s.

One hiccup, mainly at the coasts, will be the marine layer
clouds. As The 500 mb heights rise, the marine layer depth will
become more shallow, which may lead to some dense fog along the
Central Coast and some of the LA/Ventura valleys. Additionally,
slow (and maybe even limited) clearing at the beaches could keep
high temps a little cooler than currently forecast. Otherwise, some
breezy, but sub-advisory, afternoon/evening winds across the
deserts and southwest Santa Barbara County

.LONG TERM (TUE-FRI)...07/119 AM.

As the upper level low moves into Arizona on Tuesday, a little
ridge will nudge into California. This ridge will allow one final
day of warming, with high temps reaching around the mid 90s for
coastal valleys and around 100 degrees for the Antelope Valley.
Not expecting temperatures to be high enough for heat advisories.

Through the rest of the week, a trough will develop over the
Pacific NW, allowing 500 mb heights to decrease resulting in a
slow cooling trend.

.AVIATION...07/0620Z.

At 0538Z at KLAX, the marine layer was 1600 feet deep. The top of
the inversion was at 4500 feet with a temperature of 22 C.

There is a 10-20 percent chance that VFR conds prevail at KVNY,
and also a 20 percent chance of MVFR conds (no IFR) at KBUR and
KVNY. Afternoon VFR transitions may occur at sites with no
clearing 20Z Sat-03Z Sun, and there is a 20% chance of no VFR
transitions at KSMO and KLAX.

KLAX...Moderate confidence in TAF. There is a 20% chance of conds
lowering to 3SM BR BKN008 overnight. There is a 20% chance of no
clearing Sat afternoon. No significant east wind component
expected.

KBUR...Moderate confidence in TAF. There is a 20 percent chance
of MVFR conds (no IFR). Timing of VFR transition may be off by +/-
2 hours.

.MARINE...07/132 AM.

For the Outer Waters, moderate to high confidence in current
forecast. Today through tonight, high confidence in winds and seas
remaining below Small Craft Advisory (SCA) levels. For Sunday

with the highest chances across PZZ673/676.

For the Inner Waters north of Point Sal, moderate to high
confidence in current forecast. Today through tonight, high
confidence in winds and seas remaining below SCA levels. For
Sunday through Wednesday, there is a 30-50% chance of SCA level
winds in the afternoon and evening hours.

For the Inner Waters south of Point Conception, moderate to high
confidence in current forecast. Today through tonight, high
confidence in winds and seas remaining below SCA levels. For
Sunday through Wednesday, there is a 30-40% chance of SCA level
