Synopsis
Weakening offshore flow and ridging aloft will bring a warming
trend through Wednesday. A trough of low pressure will bring
cooler conditions by Friday with another round of gusty offshore
winds. Warmer conditions will likely return this weekend as weak
offshore flow lingers and a ridge aloft builds into the region.

Short term (tdy-fri)
north to northeast winds continue to weaken this afternoon and all
advisories will be allowed to expire. However, a new set of low
end wind advisories will be issued for southern santa barbara
county as models still show a decent gradient and winds below
850mb to justify it. Still some uncertainty on the strength of the
santa ana winds on Wednesday across la/ventura counties. The nam
was stronger today with the upper support than it was yesterday
but with the ridge building and the low and cold air air well to
the east this seems unlikely. MOS guidance is all pretty weak as
well. There may be a couple hours of near advisory level gusts in
the morning across the mtns mainly but will keep winds below
advisory levels for now. Gradients are stronger, which is not
uncommon for the second day of offshore events, and the air mass
is quite a bit warmer with the ridge aloft, so high temps should
jump several degrees from today. Low 90s expected for warmer
valleys, which would be close to record levels, and 70s and 80s
for coastal zones which probably won't be quite enough to reach
records.

On Thursday a trough will move into NRN california then move
southeast into southern nevada Thursday evening. This will result
in a rapid shift from offshore to onshore (an almost 7 mb 24 hour
trend from Wed from lax-dag), and several degrees of cooling,
especially for coast/valleys.

Another round of very gusty north winds expected behind the
trough Thu evening into Friday morning with speeds possibly
approaching the levels experienced last night.

Then gradients turn offshore again Friday, though air mass will be
quite a bit cooler so highs should be a few degrees cooler than
thu despite the offshore trends.

Long term (sat-tue)
a second day of offshore gradients Saturday will be accompanied
by a much warmer air mass as the upper low exits to the east and
the ridge builds. Highs not expected to be quite as warm Saturday
as tomorrow but still at least 10-15 degrees above normal. There
will be some northeast breezes but likely below advisory levels.

Gradients then shift to onshore Sunday that should lead to some
cooling but still at least a few degrees above normal in most
areas.

For Monday and Tuesday the GFS has shifted towards the much
weaker and progressive trough pattern that the ECMWF has been
advertising. It's been bouncing around quite a bit though so
confidence is pretty low for early next week, but if these trends
hold then it would certainly be a warmer and less windy forecast
than previously expected with no chance of rain. Bumped up highs
a few degrees but didn't want to adjust too much in case the
solutions reverts back to a cooler/windier one.

Aviation 28/1800z.

At 1703z at klax... There was no marine inversion.

High confidence inVFR conditions through the next 24 hours.

Klax... High confidence in the 18z taf.VFR conditions are
expected.

Kbur... High confidence in the 18z taf.VFR conditions are
expected.

Marine 28/200 pm.

Across the outer waters... Another gale warning continues as model
solutions project 45 kt gusts in the western sections late this
afternoon through much of tonight. It is a bit difficult to
monitor conditions in the coastal waters due to an outage of
observations. Small craft advisory winds will resume Wednesday
and continue into Wednesday night. By late Thursday, wind speeds
in the outer waters may again increase to gale warning criteria.

Across the inner waters... A SCA for hazardous seas is in effect
through this afternoon south of point conception due to steep and
choppy waves. Gale level winds may affect the inner waters on
Thursday and Friday.

Lox watches/warnings/advisories
Ca... High surf advisory in effect until 2 pm pdt Wednesday for
zones 34-35. (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.
