Synopsis 22 309 am.

Except for local drizzle this morning, today will be dry with partly
cloudy skies. Clouds will increase later today and tonight. There is
a chance of showers tonight and Saturday morning across northern areas.

Dry weather is expected late Saturday through Monday, with a warming
trend. There is a slight chance of showers in northern areas Tuesday,
spreading to the entire region Tuesday night and Wednesday. There
is a slight chance showers could linger into Thursday.

Short term (tdy-sun) 22 510 am.

Lots of low level moisture lingering across the region this
morning, with generally partly cloudy skies. Some stratocu
development will likely keep skies partly cloudy across l.A. And
vtu counties today. A band of thick mid and high level clouds
on the eastern side of an approaching trough and its associated
weak front will likely make for a mostly cloudy day across slo
and sba counties. MAX temps will likely be up a couple of degrees
in most areas, especially across ventura and l.A. Counties, where
heights and thicknesses will rise, temps at 950 mb will edge
upward, and there will be the most sunshine.

The trough will flatten as it moves into the region tonight and
early sat. Showers will become likely across portions of slo
county tonight, but the southern end of the front will weaken
significantly, with just a slight chance of showers extending
southward into southern sba county late tonight. Locally gusty
north winds thru and below passes and canyons of the santa ynez
mountains will hasten the demise of the band of rain. Expect just
an increase in clouds across vtu and l.A. Counties tonight.

Skies will start out mostly cloudy across the region on Saturday,
then it will become partly cloudy. There is a slight chance of
showers across slo and sba counties and in the northern mtns
in the morning, possibly lingering into the afternoon across the
mtns, and across far eastern sections of slo and sba counties.

Max temps on Sat should be similar to those reached today in most
areas, with some cooling possible in the mtns and deserts. Gusty
northwest winds will affect the central coast in the afternoon and
evening, and gusty southwest to west winds in the antelope valley
could approach advisory levels. It will also be breezy across
coastal sections of l.A. And vtu counties in the afternoon.

Heights will rise across the forecast areas Sat night Sun as a weak
ridge builds into southern california. Skies will generally be
mostly clear. Gusty northwest to north winds will affect locations
through and below passes and canyons of the santa ynez range and
through the interstate 5 corridor Sat night. With rising heights
and thicknesses, warming at 850 mb and 950 mb, and very weak
offshore gradients in the morning, expect several degrees of
warming in most areas sun, with MAX temps getting close to normal.

Long term (mon-thu) 22 421 am.

Another weak trough will approach the region on mon, swinging into
northern ca Mon night. This will cause clouds to increase in
northern areas. There is a slight chance of rain across far
northern sections, mainly in the afternoon. South of pt
conception, heights thicknesses will remain rather high, and
onshore flow will be weak. Therefore, MAX temps may actually rise
a bit more, especially in the valleys of l.A. And vtu counties.

There is a slight chance of showers across slo county Mon night,
and some showers could make it into sba county on tue, but overall
the frontal system associated with the approaching trough is
expected to fade out. The remainder of the region should remain
dry, with an just an increase in clouds and some cooling.

A sharper trough will approach the west coast Tue night and wed.

Models continue to be oscillating as to how far south the rain
will get Tue night and wed, but many of the ensemble members
bring some rain to the entire region, especially during the day on
wed. At this point, it 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 point conception. Some showers
may linger across the region Wed night and thu, but any additional
rainfall will be very light.

Aviation 22 1207z.

At 1150z, there was no marine layer or inversion at klax.

Moderate confidence with 12z tafs. There is a 30% chance that MVFR
cigs could develop across valley TAF sites and linger into this
afternoon. There is a 30% chance that ifr CIGS at kprb could
linger a few hours this morning. For coastal sites, MVFR cigs
could develop up to 3 hours before tafs suggest this evening.

Moderate confidence with vcsh for NRN taf sites.

Klax... Moderate confidence in the 12z taf. 30% chance that MVFR
cigs will develop through 17z this morning. There is a 30% chance
that MVFR CIGS will develop + - 2 hours from taf. 10% chance for
east winds over the next 30 hours.

Kbur... Moderate confidence in the 12z taf. There is a 30% chance
that MVFR CIGS will be + - 2 hours from TAF this evening or
tonight.

Marine 22 330 am.

Outer waters... High confidence for the northern zone (pzz670) for
winds to remain below small craft advisory (sca) levels through
this weekend. However by Saturday, a swell of 10 feet or greater
is expected. Later shifts will likely issue a (sca) for hazardous
seas for all the outer waters through Sunday night where winds are
not meeting SCA levels. There is a 60% chance that the southern
zone (pzz676) will have SCA level wind gusts by mid afternoon
through tonight.

Inner waters N of point conception... High confidence for winds to
remain below (sca) through at least this weekend, and likely into
early next week. There is a 20% chance for SCA for southerly
winds late Sunday through early Monday morning.

Inner waters S of point conception... There is a 60% chance for
(sca) westerly wind gusts across much of the santa barbara channel
and a 50% chance across the NW portion of the southern inner
waters (pzz650) by this afternoon, and continuing overnight into
early Saturday morning. There is 30% chance that SCA level winds
do not materialize and SCA might need to be taken down. Strongest
winds will be across western portion of zone pzz655) confidence is
lower tomorrow for SCA level gusts as winds have become weaker
with latest model runs.

Beaches 22 444 am.

A high surf advisory has been issued for the central coast valid
from early Saturday morning through Sunday evennig. A relatively
large, long period west-northwest swell has developed across the
central pacific. This swell will move towards the central coast
late tonight or early Saturday morning. Surf between 8 and 12 feet
will initially affect the central coast Saturday morning, then
increase to between 10 and 14 feet by Saturday afternoon through
Saturday night with local sets to 16 feet during the peak of the
high surf. Surf will lower slightly on Sunday to between 9 and 13
feet.

There is a good chance that some of the swell energy will make it
into the inner waters allowing for elevated surf 4-7 feet across
west facing exposed beaches from santa barbara to los angeles
county Saturday through Sunday. A beach hazards statement or low
end high surf advisory might need to be added for Saturday
afternoon through Sunday. Will let the next shift make that
determination.

High rip currents will be increasing and can pull swimmers and
surfers out to sea. Large breaking waves can cause injury, wash
people off beaches and rocks and jetties. Swim near a lifeguard
station if entering the surf zone this weekend.

Lox watches warnings advisories
Ca... High surf advisory in effect from 1 am Saturday to 10 pm pdt
Sunday for zones 34-35. (see laxcfwlox).

Pz... Small craft advisory in effect from 3 pm this afternoon to 3
am pdt Saturday for zones 650-655-676. (see laxmwwlox).

weekend.
