.SYNOPSIS...27/1204 AM.

Night and morning low clouds and fog will affect the coasts and
some valleys, otherwise mostly clear skies are expected across
the area with gusty onshore winds each afternoon. Temperatures
will change little over the weekend and into early next week.

&&

.SHORT TERM (TDY-MON)...28/302 AM.

Very uneventful weather on tap for the next three days (actually
the next 7). At the upper levels a high hgt (~581 dam) upper low
will spin to the west of Pt Conception. Hgts over the area will be
around 584 dam. At the sfc there will be weak to moderate onshore
flow in the morning which will strengthen with the diurnal cycle
to mdt to stg in the afternoon. There will be little change to
this pattern through Monday.

There is no eddy this morning so the low clouds are filling slower
than last night and will likely not cover the vly areas a few
miles either side of the VTA/LA county lines. Look for decent
clearing by this afternoon with only the western beaches of VTA
and SBA counties remaining cloudy. Hgt are a few dam higher than
ydy and this should lead to a degree or two of warming away from
the coasts.

Maybe a little less low clouds in the vlys tonight and Sunday
morning as the gradients are forecast to slacken just a bit. This
will also bring another degree or two of warming to the vlys. The
vlys will see max temps in the upper 80s to the mid 90s. These vly
temps are 3 to 5 degrees above normal.

A little better onshore flow on Monday will translate to an
earlier arrival of the low clouds and more complete vly coverage.
Max temps will cool by 2 to 3 degrees.

No wind issues are forecast. Gusty southwest winds will continue
each afternoon/evening across interior sections with some weak
Sundowners each evening. Any advisory-level winds will remain very
localized, if develop at all.

.LONG TERM (TUE-FRI)...27/1148 PM.

The dull June Gloom weather will persist through the xtnd period.
Both the EC and GFS are in good agreement and forecast weak
cyclonic flow through the period. Hgts will not change much and
will hover around 584 dam.

The night through morning low cloud pattern will continue
unchecked over the csts and vlys, while the interior will see only
clear skies. The afternoon onshore push will be near 8 mb which
will result in slower than normal clearing with some beaches
staying cloudy for most or all of the day.

There will be little in the way of day to day temperature change.
Any change will result from little variations in the marine layer
depth and onshore flow. Max temps will be in the upper 60s to
lower 70s near the csts, mid to upper 70s for the inland cstl
sections, mostly 80s in the vlys and finally upper 80s and 90s
across the lower mtn elevations and far interior. Most max temps
will be 3 to 6 degree below normal with the exception of the
Antelope Vly which will be 2 to 3 degrees over normal.

With continued strong afternoon onshore pressure gradients, gusty
southwesterly winds can be expected each afternoon/evening across
interior sections. However, speeds should remain below advisory
levels.

.AVIATION...28/0554Z.

At 0512Z at KLAX, the marine layer was 1300 ft deep. The top of
the inversion was at 2900 ft with a temperature of 24 deg C.

High confidence in VFR TAFs for KPRB, KPMD and KWJF.

Moderate confidence in remaining TAF sites, except low to moderate
confidence for KBUR and KVNY. Timing of arrival of cigs and
flight cat changes may be off +/- 2 hours. Minimum flight cat may
be off by one, with lower confidence in minimum flight cats at
KBUR and KVNY. There is a 30% chance cigs do not reach KBUR nor
KVNY tonight and VFR conds prevail.

KLAX...Moderate confidence in the 06Z TAF. High confidence in
cigs persisting thru about 17Z Sat. Low clouds and mostly IFR cigs
should move back into the airfield by 05Z Sat evening. Moderate
confidence in timing (+/- 2 hours) and minimum cig height (+/- 300
feet). Moderate confidence that any southeast winds will stay
under 6 knots.

KBUR...Low to moderate confidence in the 06Z TAF. There is a 30%
chance cigs do not move into the airfield tonight and VFR conds
prevail. If cigs arrive, there is a 40% chance of cigs 002-004.
Timing of arrival may be off +/- 2 hours.

&&

.MARINE...28/119 AM.

High confidence in winds and seas remaining well below Small Craft
Advisory (SCA) levels for all coastal waters today through
Wednesday.

Winds in the outer waters are forecast (50% chance) to increase
to SCA levels Wednesday night, while seas increase to SCA levels
for the northern Outer Waters (PZZ670). Conds over the inner
waters will likely remain below SCA levels Wednesday night.

Patchy night to morning dense fog is possible through the weekend
off the Central Coast.
