Synopsis
Strong high pressure aloft and moderate santa ana conditions will
bring continued record heat to many areas into today. The ridge
will break down through Thursday, allowing for a gradual cooling
trend. A ridge of high pressure may try to rebuild early this
weekend, bringing a rebound in temperatures.

Short term (tdy-thu)
another day of recorded breaking heat is in store for the
southland. A 597 dm upper high sits atop of the state. At the sfc
there is about a 6.5 mb offshore push from both the north and the
south. Unlike last night the northeast to east winds have already
surfaced and these winds are keeping the overnight lows very warm.

There will be many min temps in the 80s this morning and would not
be surprised to see one or two lows in lower 90s. With temps
running anywhere from 5 to 20 degrees warming in most location
than at this time ydy cannot see any reason why MAX temps will not
be 1 to 3 degrees warmer than ydy. 10 or more records will likely
fall today including the record for warmest temp at the opening
pitch at a world series game. Excessive heat warnings and
advisories blanket the forecast area and everyone needs to be
mindful of heat related dangers today. Today will be the windiest
day with plenty of advisory level gusts 20 miles either side of a
line from santa clarita to pt mugu. There will be a few isolated
gusts to 60 mph across the exposed ridgetops as well. Forest fire
conditions will be critical as well... See the discussion below for
details. See the product laxnpwlox for details on all of the heat
and wind advisory warnings.

The gradients weaken Tuesday night but there will still be 3 to 4
mb offshore flow from both the north and east. These gradients
will be strong enough to keep some winds going overnight and there
will be another night a very warm minimum temps. There likely be
just enough of a push to create low end advisory gusts across the
same la to vta county area.

The upper high weakens as well on Wednesday and hgts fall to about
589 dm. The weaker offshore flow and lower hgts will allow for
some cooling everywhere ESP the central coast and the beaches.

Depending on the overnight lows the heat advisories may need to be
extended into Wednesday afternoon. The advisory level wind gusts
will end either in the late morning or early afternoon.

On Thursday hgts fall to 585 dm and the morning offshore flow
weakens to about 2 mb from both the north and east. This will lead
to about 4 to 8 degrees of cooling with MAX temps "only" 8 to 12
degrees above normal.

Long term (fri-mon)
the ridge will persist into Friday only to be replaced by a
smaller ridge poking in from the SW over the weekend. While it
doesn't look like the marine layer will return in strength over
the weekend, it does appear that the rh levels will finally rise
above the 10-20 percent levels with at least some high clouds
helping to cool things down. Gradients are only weakly offshore
so temps, winds and fire danger will be above normal they will be
nothing like they are now. The GFS (the ec mdl was unavailable
this morning) does show some trofing on Monday which would bring a
decent cool down to the area.

Aviation
24 0930z
at 0900z, there was a surface-based inversion at klax. The top of
the inversion was 800 feet with a temperature of 34 degrees
celsius.

Overall, high confidence in 12z tafs as moderate northeast flow
will keep all sitesVFR through the period. With offshore flow,
llws and turbulence will be issues over and near the higher
terrain.

Klax... High confidence in 12z taf. There is a 10% chance of east
winds greater that 8 knots 12z-20z.

Kbur... Moderate confidence in 12z TAF with MVFR blowing dust ash
layer through 22z. There will be occasional llws and light
turbulence 14z-22z.

Marine
24 130 am
for the outer waters, high confidence in current forecast. Other
than small craft advisory (sca) level northeast winds across
pzz676 today, winds and seas are expected to remain below sca
levels for the outer waters through Saturday.

For the inner waters, high confidence in current forecast. For the
waters north of point sal, winds and seas will remain below sca
levels through Saturday. For the waters south of point conception,
sca level northeast winds are expected today from ventura south to
santa monica with some local gale force gusts nearshore. For
tonight and Wednesday, there is a 40% chance of SCA level
northeast winds from ventura south to santa monica. For Thursday
through Saturday, winds and seas will remain below SCA levels.

There is a chance that the northeast winds will reach avalon and
two harbors on today, but since this is a hot santa ana event the
likelihood of significant winds out that far is small. 30 percent
chance of 10-20 kt winds in the harbors, 10 percent chance of
15-25 kt.

Lox watches warnings advisories
Ca... Heat advisory in effect until 8 pm pdt this evening for zones
34>36-39-88. (see laxnpwlox).

Excessive heat warning in effect until 8 pm pdt this evening
for zones 40-41-44>46-87-547. (see laxnpwlox).

Wind advisory in effect until 2 pm pdt Wednesday for zones
40-41-44>46-53-54-88-547. (see laxnpwlox).

Red flag warning in effect until 6 pm pdt Wednesday for zones
240-241-244>246-253-254-288-547-548. (see laxrfwlox).

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

Hazard potential outlook (thu-mon)
heat advisory level temperatures may continue for many areas into
Wednesday. Gusty northeast winds will likely impact wind prone
areas of los angeles and ventura counties through early
Wednesday. Hot, dry and windy conditions will likely bring
continued critical fire weather conditions to some areas
Wednesday.

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.
