Synopsis 23 742 am.

A weak low pressure system will bring a chance for rain to
northern areas and the mountains today. Expect temperatures to
warm through Monday. The next chance for rain will be late Monday
into Tuesday for area north of point conception. By Tuesday night,
showers are possible throughout the region. Dry weather returns
on Thursday.

Short term (tdy-mon) 23 908 am.

A weak cold front was along the central coast this morning with
showers moving into that area. The cold front will weaken further
while moving inland thru this afternoon, with additional showers
expected mainly over slo sba counties, altho a few rain and snow
showers cannot be ruled out for mtns of vtu l.A. Counties.

Otherwise, a deep moist layer and some onshore flow will keep
partly to mostly cloudy skies over much of the coast vlys coastal
slopes of vtu l.A. Counties into this afternoon. Further north,
partly cloudy conditions should develop for most of slo sba
counties this afternoon as the front moves east. Gusty NW winds
are expected this afternoon along the central coast and in the
mtns especially along the i-5 cooridor. Temps across the region
today will be a few degrees cooler than normal for most areas.

Highs for the warmest coast and vlys should only reach the 60s
today.

A weak upper level trof over the forecast area today will move e
tonight with weak upper level ridging expected thru sun. The weak
ridging will move E Sun night as a broad upper level trof over the
e pac approaches the coast thru mon.

There may be a stray shower along the N mtn slopes of vtu l.A.

Counties this evening, otherwise clearing skies and offshore flow
can be expected across the forecast area tonight and sun. Gusty nw
winds near advisory levels will affect the vtu l.A. County mtns
tonight into early Sun morning, especially along the i-5 corridor,
as well as over the antelope vly. Gusty sub-advisory level NW to ne
winds can also be expected for slo sba counties tonight into sun
morning, especially over higher terrain and below and through passes
and canyons of the santa ynez range and sba county S coast.

For Sun night and mon, mostly clear skies should prevail for
l.A. Vtu counties. However, a weak cold front should approach NW slo
county Sun night and Mon with some clouds moving in. A few showers
cannot be ruled out in far NW slo county Mon afternoon as well.

Otherwise, dry weather should prevail thru Mon across the forecast
area.

Temps on Sun with the offshore flow and increasing 1000-500 mb
thicknesses 850 mb temps boundary layer temps will be much warmer
and a few degrees above normal for many areas. This warming trend
should continue Mon for vtu l.A. Counties, while temps remain
unchanged or cool slightly over slo sba counties. Highs in the
warmest vlys and coastal areas should reach the low to mid 70s on
sun, and 70s on Mon especially for l.A. Vtu counties.

Long term (tue-fri) 23 435 am.

The next broad trough will move into the eastern pac and into
northern ca Mon night early tue. Its associated frontal system
will weaken as it moves into ca, with its southern end possibly
holding together enough to bring a chance or slight chance of
showers to slo county Mon night, with a slight chance of showers
spreading into sba county tue. Elsewhere, there will be increasing
mid and high clouds on tue. MAX temps should be down a few degrees
in most areas, especially north of pt conception where clouds
will be thickest and there will be a chance of showers.

An upper low will move thru the eastern pac Tue night and into
northern ca wed. Its frontal system will likely be stronger and
wetter, and has a better chance of bringing rain to the entire
region. The best chance of rain looks to be Tue night Wed morning
n of pt conception, and Wed early Wed night south of pt conception.

The ec continues to be wetter than the GFS with this system. At
this point, it still looks as though rainfall totals will be on
the light side, generally one quarter of an inch or less, except
possibly higher in areas north of pt conception. Some showers may
linger across the region Wed night. Drier NW flow will bring
decreasing clouds on thu, and there will be some warming. Upper
ridging should bring additional warming fri, with MAX temps
possibly rising to above normal levels. The GFS shows less ridging
than does the ec, and consequently less in the way of warming.

Aviation 23 1156z.

At 1114z around lax, there was a deep moist layer with no
inversion.

N of point conception... Low confidence with 12z tafs through 20z
due to weak frontal boundary moving through. CIGS could vary from
MVFR toVFR with 30% chance of brief ifr CIGS as trough pushes
through from kprb to ksmx. Confidence increases to mainlyVFR
after 20z. There is a 20% chance for lifr ifr CIGS across kprb
after 10z early Sunday morning.

S of point conception... Moderate confidence with 12z tafs. Mainly
MVFR conds through 17z across coast and valley tafs. Higher
confidence withVFR conds after 18z. 20% chance for MVFR cigs
after 06z this evening into early Sunday morning across coast and
valley TAF sites.

Klax... Moderate confidence thru 20z. 30% chance that MVFR cigs
will continue after 18z. Higher confidence forVFR conds after
20z. There is a 30% chance for east winds greater than 10 kt
through 16z this morning.

Kbur... Moderate confidence thru 20z. 30% chance that MVFR cigs
will continue after 18z. Higher confidence forVFR conds after
20z.

Marine 23 854 am.

For the outer waters, high confidence in current forecast through
Tuesday then moderate confidence on Wednesday. Combination of a
long- period westerly swell and gusty post- frontal winds will
generate small craft advisory (sca) level winds and seas today
through Sunday morning. By Sunday afternoon, the winds and seas
will subside and remain below SCA levels through Tuesday. On
Wednesday, there is a 40% chance of SCA level winds.

For the inner waters north of point sal, high confidence in
current forecast. SCA level seas will develop today as a large
westerly swell moves into the waters with a 60% chance of winds
reaching SCA levels. The SCA level seas, and potentially, winds
will continue through Sunday morning. From Sunday afternoon
through Wednesday, winds and seas will remain below SCA levels.

For the inner waters south of point conception, moderate
confidence in current forecast. There is a 60% chance of SCA level
winds across the sba channel (pzz650) through this evening and a
30% chance of SCA level winds across pzz655. For Sunday through
Tuesday, winds and seas are expected to remain below SCA levels.

On Wednesday, there is a 50% chance of sca-level winds developing.

Beaches 23 854 am.

A long 18 second period west to northwest swell moving into the
coastal waters is expected to peak later today. While periods
will drop to about 15 seconds during the peak this afternoon,
the combination of size and period will be enough to generate high
surf on the central coast between 10 and 14 feet. Surf will also
build along the west facing beaches south of point conception,
especially along the ventura county coast where waves should peak
in the 5 to 8 feet range. There is a chance that some spots on the
los angeles county coast will also see waves of 7 feet. As a
result, a high surf advisory is in effect for these areas. The
exposed west facing beaches of santa barbara county, like rincon,
could also see waves near 7 feet, but surf will be localized and
should need an advisory. The swell and surf should gradually
subside on Sunday.

Waves like this pose a serious risk to anyone that enters the
ocean. Strong and deadly rip currents will be happening. Please
emphasize the special risk of anyone on the rock jetties, as there
is a long history of fatalities from people that go on the rocks
and tide pools during such events.

Lox watches warnings advisories
Ca... High surf advisory in effect until 9 pm pdt Sunday for zones
34-35-40-41-87. (see laxcfwlox).

Pz... Small craft advisory for hazardous seas in effect until 9 am
pdt Sunday for zones 645-670. (see laxmwwlox).

Small craft advisory in effect from 3 pm this afternoon to 9
pm pdt this evening for zone 650. (see laxmwwlox).

Small craft advisory in effect until 9 am pdt Sunday for
zones 673-676. (see laxmwwlox).

Hazard potential outlook (mon-fri)
No significant hazards expected.
