.SYNOPSIS...05/441 PM.

Light offshore winds will weaken through tonight. Benign weather
will continue through the weekend with a low chance of morning
coastal low clouds and fog. A significant warming trend will
begin Sunday with temperatures well above normal Monday through
next Friday, peaking Tuesday through Thursday. Offshore winds will
increase Sunday and Monday and continue into much of the week.

.SHORT TERM (TDY-MON)...06/1242 AM.

A Chamber of Commerce weekend is on tap for Srn CA. A ridge poking
in from the west bringing hgts around 582 dam. Weak offshore flow
should keep the low clouds away, but there is about a 10 percent
chc that the LA south coast and SBA county west coast will see
some morning low clouds and dense fog. There may be some local
canyon winds in the morning, but nothing near advisory levels.

Max temps will be the main talking point. Weaker offshore flow
this morning will bring some cooling to the VTA/LA csts and vlys.
But the rest of the area will see warming esp the Antelope Vly
where the lack of cool air advection will bring 8 to 10 degrees of
warming. On Sunday, sunny skies, higher than normal hgts and the
offshore flow will all combine to bring 3 to 6 degrees of warming
to the csts/vly S of Pt Conception and 1 to 2 degrees of warming
elsewhere. Sunday`s max temps will be 3 to 5 degrees above normal
at the csts and 5 to 10 degrees inland.

Stronger offshore flow will bring 20 to 25 mph canyon gusts to
some areas in the morning. Hgts rise to 584 dam and this along
with the better offshore flow will allow max temps to rise 3 to 6
degrees to the csts/vly S of Pt Conception and 1 to 2 elsewhere.
This warming will bring some max temps up into the lower 80s in
the warmest LA/VTA vly areas. Most areas away from the coast will
end up 10 to 12 degrees above normal.

.LONG TERM (TUE-FRI)...06/255 AM.

The GFS has now trended towards the warmer EC solution and it
seems pretty certain that all of next week will be a very warm
one. Upper level high pressure will sit atop of the state and hgts
will vary between 584 dam and 586 dam. These hgts are about 15 dam
higher than the normal value of 571 dam. Offshore flow will
continue through the period with a peak on Tuesday.

Cannot rule out some morning low clouds in the LGB-LAX area on any
given morning but right now it looks like the chance of this
happening is under 50 percent.

There will be some canyon winds but the only chance of advisory
level gusts will be Tuesday morning and they will be more from the
north than the NE.

Max temps will be the name of the game for the entire week.
Coastal temperatures will vary the most heating or cooling
depending on the sfc gradient trends. The current thinking for
coastal temps is for for a 3 to 5 degree rise on Tuesday bring max
temps into the mid 70s to lower 80s (lower 70s right at the
beaches). A degree or two of cooling each day Wed and Thu will
bring the temps down into the upper 60s and 70s. Most coastal max
temps S of Pt Conception will be 4 to 8 degrees above normal. The
Central Coast will exceed that with temps coming 10 to 15 degrees
over normal. The interior will see two days of warming Tue and Wed
and then little change Thu and Fri. People can expect to see 80s
in the vlys (with a 30 to 40 percent chc of some lower 90s). The
lower elevations of the mtns and all of the far interior will have
max temps in the 70s. These max temps are 12 to 18 locally 20 degrees
above normal.

Looking further ahead it appears that there will be some cooling
next weekend but max temps will remain well above normal.

.AVIATION...06/1040Z.

At 0910Z, there was no marine layer depth at KLAX, but there is a
surface-based inversion up to around 2000 feet with a temperature
around 17 degrees Celsius.

VFR conditions are expected through at least 03Z Sunday, but there
is a very low chance of VLIFR to LIFR conditions through 16Z at
coastal terminals. After 03Z Sunday at coastal terminals, there
is a low-to-moderate chance of VLIFR to LIFR conditions through
08Z Sunday increasing to a moderate chance of VLIFR to LIFR
conditions after 08Z Sunday.

KLAX...There is a less than 10 percent chance of VLIFR to LIFR
conditions through 16Z, otherwise VFR conditions are expected.
There is a 20 percent chance of VLIFR to LIFR conditions after 03Z
Sunday increasing to a 30 percent chance after 08Z Sunday. Any
east winds should remain less than 7 knots.

KBUR...VFR conditions are expected through the period. No wind
impacts are expected at this time.

.MARINE...06/240 AM.

Moderate confidence in current forecast.

For the waters southwest through northwest of the Channel Islands
beyond 10 NM offshore of the Central Coast, there is a high-to-
likely (40 to 70 percent) chance of low-end Small Craft Advisory
(SCA) northwest winds through the much of next week, especially
across the northern and western portions during the afternoon and
evening.

Inside the southern California bight, winds and seas will very
likely remain below SCA levels through Monday night, then there is
a moderate (30-40 percent) chance of SCA level north to northeast
winds from Ventura through Santa Monica through Tuesday afternoon.
Winds and seas should remain below SCA levels thereafter.

There is a moderate-to-high chance of dense fog over the coastal
waters this morning increasing to high chance tonight through
Sunday morning. Confidence remains low on timing and coverage.
