Synopsis 18 721 pm.

Temperatures will warm each day into midweek then cool again into
next weekend. Many locations will have triple digit temperatures
Wednesday and Thursday. Overnight and morning low clouds and fog
will diminish in area a bit each day through Thursday then expand
again beginning Friday.

Short term (tdy-wed) 19 316 am.

The marine layer is 1100 ft deep. There is 2 to 4 mb of onshore
flow in all directions. The eddy was very late to spin up and low
clouds have been late to form south of pt conception. The central
coast and the northern half of the slo interior are already full
of clouds. By dawn low clouds should cover the la and vta coasts
as well as the san fernando and san gabriel vlys. There will be
much less clouds in the vta vlys and the sba south coast. There
are 2 mb offshore trends and these should bring a quicker and more
complete clearing than ydy. Slightly higher hgts and weaker
onshore flow will allow almost all areas to warm 2 to 4 degrees
today.

Offshore trend will continue tonight and there will be much less
low clouds in the vlys and the sba south coast will also remain
clear.

Hgts rise to 591 dm on Tuesday as socal will be sandwiched
between pac NW trof and a new mexico upper high. There will only
be weak onshore flow and the higher hgts, reduced marine layer and
delayed and weaker seabreeze will combine to warm temps 2 to 4
degrees across the board. MAX temps will be above normal across
the interior, near normal in the vlys, slightly below normal over
the interior coastal sections and well blo normal near the
beaches.

A 3 to 4 mb offshore push from the north is forecast to quickly
develop Tuesday night. There will only be weak onshore flow to the
east. Marine layer stratus will be confined to the la south coast
and the central coast. The ksba-ksmx grad peaks at -3.9 mb and
this should be enough to bring wind advisory gusts to the sba
south coast ESP west of the airport.

The mdls have changed their tune for Wednesday. The upper high is
no longer forecast to move to the west and in fact trof will be
over the north half of the state. Hgts will still be high, there
will be offshore flow from the north and minimal marine layer so
it will still be a warm day but perhaps not as warm as previously
thought.

Long term (thu-sun) 19 326 am.

Not much change on Thursday. Skies will be mostly sunny with very
little in the way of low clouds. A little less offshore flow so
the coasts and vlys will cool a little. Still MAX temps will be
above normal across the interior.

The GFS and ec disagree on the Friday through Sunday forecast.

Both mdls agree that there will be some sort of weak upper high
overhead with hgts near 592 dm. The big difference is with the sfc
gradients. The GFS has mdt to strong onshore flow while the ec has
much weaker onshore flow and even some offshore flow. The gfs
solution would be cooler with more marine layer while the ec would
be warmer and clearer. The ec is the big departure from previous
so trended the fcst to the gfs.

The tropical system forecast to spin near baja Friday through
Monday is still there but it is weaker and right now does not look
like it will have much impact on la county and north. Still
tropical systems can be tricky and cannot take our eyes off of it.

Aviation 19 1259z.

At 12z, the marine layer was around 2200 ft deep at klax. The top
of the inversion was around 3500 ft with a temp of 22c.

North of pt conception, low clouds were widespread in all coastal
and valley areas with the exception of the far interior valleys of
slo county and the cuyama valley. Conds were mostly ifr to lifr.

Skies should clear by mid morning in the valleys and late morning
or early afternoon across the coastal plain. Expect clouds to push
into coastal areas and the santa ynez valleys this evening, and
possibly into the salinas valley late tonight. Conds should be ifr
to lifr once again.

South of pt conception, clouds have pushed into coastal areas of
l.A, county and the san gabriel and san fernando valleys, and will
likely push into the vtu county coastal plain, eastern parts of
the sba county south coast. Conds will be mostly ifr, except low
MVFR across the l.A. County coast. Skies should clear by mid
morning in the valleys and late morning on the coastal plain,
except early afternoon at some beaches. Expect marine layer to be
a bit more shallow tonight, with less cloud coverage in the
valleys, and mostly ifr conds. Also, sundowner winds may keep
south coastal sections of sba county and coastal sections of vtu
county clear, at least through 12z.

Klax... Moderate confidence in the 12z taf. There is a 20% chance
that CIGS will linger until 20z. There is a 20% chance that cigs
tonight will arrive as early as 06z. There is a 30% chance that
cigs tonight will be in the MVFR category instead of ifr.

Kbur... Moderate to high confidence in the 12z taf. There is a 20%
chance of ifr CIGS after 09z tonight.

Marine 19 333 am.

For the outer waters, moderate to high confidence in current
forecast. Small craft advisory (sca) level winds are expected
to develop this afternoon and continue through at least late tue
night, and possibly through late Thu night. There is a 50-60%
chance of a period where winds drop below SCA levels late tue
night and Wed morning.

For the inner waters north of pt sal, only fair confidence in
forecast beyond today. No SCA level conds are expected today.

There is a 40-50% chance of SCA level winds during the afternoon
and evening hours Tue through thu.

For the inner waters south of point conception, SCA level conds
are not expected through fri. The exception is across western
portions of the SCA channel, where there is a 20-30% chance of sca
level NW winds this evening, and SCA level NW winds are expected
during the late afternoon through late night hours Tue and wed,

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect from 3 pm this afternoon to 3
am pdt Wednesday for zones 670-673-676. (see laxmwwlox).

Hazard potential outlook (wed-sun)
Hot temperatures could lead to heat advisories for some inland
areas Wednesday and possibly Thursday. Otherwise, no significant
hazards are expected through the period.

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.
