Synopsis
High pressure centered over southern arizona will continue to
bring very warm conditions to all areas except the coast through
early next week. Night through morning low clouds and fog will
continue into next week. High pressure aloft will weaken Tuesday
and a cooling trend should develop as onshore flow increases.

Short term (tdy-mon)
the marine layer has shrunk a few hundred feet (its at 1400 feet
now)... There are weak offshore trends from the north and the
powerful ridge continues to sit directly atop the state with 594
hgts. All of this will add up to another very warm day with little
change from the very hot temps across the interior and the cool
temps across the coastal areas which are swaddled in cool marine
air. The vlys will see a bump up in temps of 2 to 4 degrees as the
marine layer retreats.

The offshore trends will allow for a little better clearing of the
marine layer this afternoon but more than a few west facing
beaches will likely remain cloudy.

A little instability and some mid level moisture is working its
way up from the north. This is creating some elevated convection.

There is a slight chc of some dry lighting this morning from this
system but the only chc or rain and thunder is over the southern
outer waters where the convection has been training for the past 7
hours. The mtns and ESP the vta mtns are rather unstable today and
there is even some decent CAPE to complement the instability but
there is still no low level moisture so still expecting a large
field of ACCAS but not much else. The chc of a mtn TSTM is not
zero but it is too low to mention in the forecast. Would not be
too surprised if there were a few reports of big raindrops.

Continued offshore trends tonight will result in a greatly reduced
marine layer. Quite confident that the vlys will be clear and that
most of the central coast and the la coast will be cloudy but the
vta county coast is the big question mark. Keeping it clear for
now but would not be surprised if the clouds sneak in late.

The ridge begins to break down on Sunday and this will result in
some cooling across the interior including the antelope vly which
will see its first slight relief in a week. But the offshore
trends and reduced marine layer will bring a warming trend to the
coasts and vlys.

The ridge continues to flatten out on Monday so the cooling trend
will continue across the interior and will spread to the coasts
and vlys which will have a similar marine layer and pressure
gradient pattern as Sunday but lower hgts overhead.

Long term (tue-fri)
the ec blinked first and after 3 days of disagreement now
resembles the GFS through the xtnd period. An upper low rolls
through the canadian rockies and a long wave trof will slowly
develop and expand across the western conus. There will be
continued cooling Tue and Wed and then Thu and Fri will see little
change. The marine layer will grow Tue and Wed when it will cover
most of the coasts and vlys. The marine layer stratus pattern will
then also change little on Thu and fri.

Aviation 24 1140z
updated at 1314z
at 1030z near klax, the marine layer depth was around 1400 feet.

The top of the inversion was around 4300 feet with a temperature
near 30 degrees celsius.

Only moderate confidence in coastal and vly tafs. There is 40
percent chc that low clouds will reach kvny and kbur. There is a
30 percent chc that TAF sites with no afternoon clearing forecast
will clear by 22z. Low confidence in low clouds redevelopment
after 00z for all coastal tafs. Better confidence thatVFR conds
will occur across sba,koxr,kcma this evening through overnight
hours due to northerly winds.

Klax... Moderate confidence in taf. There is a 30 percent chc that
there will be clearing by 22z. Low confidence in TAF after 00z
with a 40 percent chc ofVFR conds. For west departures through
18z there is a 20 percent chc of lightning 100 nm west of the
terminal.

Kbur... Low to moderate confidence in TAF through 17z. There is a
40 percent chc of ovc004 conds 14z-17z. Good confidence in taf
after 17z through the overnight hours. There is a 20% chc of
bkn006 after 09z.

Marine 24 300 am.

Outer waters... Winds will gradually increase through the weekend,
increasing above small craft advisory levels this morning for the
two lower outer water zones from point sal to NW of san nicolas
island. By this afternoon, the outer northern waters will
increase to SCA level winds as well. Small craft advisories for
the outer waters have been extended through at least late Sunday
night, and will likely need to be extended into early next week.

Inner waters... N of point conception, SCA will be in effect this
afternoon through mid evening hours. This will be on the low end
of the scale. There will be a 50% chance that SCA will be needed
Sunday afternoon and evening, and a 70% chance for Monday
afternoon and evening.

S of point conception... A SCA has also been issued valid for
this afternoon through mid evening foe the western portion of the
sba channel. Otherwise winds should remain below SCA for the other
portions through Sunday morning. Otherwise winds will remain
below SCA levels for the inner waters through Sunday. Sunday will
be similar to today except slightly windier across zone pzz655
from pt. Mugu to san mateo pt. There is a 60% that SCA will be
needed once again for the sba inner waters western portion Monday
afternoon.

A short-period west to northwest swell with a period around 6
seconds could impact the coastal waters between Monday and
Wednesday. A mix of short-period seas and or winds could develop
across the entire coastal waters into midweek next week.

Otherwise, a 2-3 foot south swell with a 16-17 second period will
last through today and may pose a risk for breaking waves
nearshore. People boating or kayaking near shore should use extra
caution.

Lox watches warnings advisories
Ca... Heat advisory in effect until 9 pm pdt Sunday for zones
38-52>54. (see laxnpwlox).

Beach hazards statement in effect through this evening for
zones 40-41-87. (see laxcfwlox).

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
