Synopsis
The santa ana winds have weakened and will fade all together as
winds turn weakly onshore on Friday. Patchy night and morning low
clouds and fog may return near the coast with a greater return
expected for the weekend. A weakening low pressure system is
expected to move inland across southern california and northern
baja on Tuesday, bringing more cooling and a deeper marine layer.

Precipitation from this system is not expected at this time. An
upper trough pattern late next week favors an opportunity for
precipitation across the state, including southern california,
for the thanksgiving holiday weekend.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

the santa ana winds have weakened and will fade away all together
by Friday. The offshore surface pressure gradient is lessening and
will eventually become weakly onshore on Friday. This will allow
for onshore wind flow to take over and erode away, slowly, the
very dry air in place at the surface as relatively higher humidity
moves in from the ocean. See fire discussion below for
humidity wind details. Definitely a huge improvement from recent
days, but low humidity remains inland.

The weather pattern will be tranquil Friday and through the
weekend. As the marine layer returns, fog is a potential we are
looking at closely. Fog prospects tonight through Friday morning
look low. There is a better chance of fog, potentially dense,
Friday night through Saturday morning near the coast.

Next week will see a pattern change. A cut off low will develop
over the pacific and head in our direction, but as it moves
towards us the low weakens and the bulk of the moisture moves over
mexico. Global models are keeping any light rain over the ocean or
to our south. So it is not looking like any rain with this system.

Operational global model runs keep wavering on placement of upper
trough pacific storms for the thanksgiving holiday weekend. The
gfs ensemble mean does show precip, albeit light, starting in
socal late thanksgiving day, and more so Friday or into next
weekend. The favored areas for appreciable precipitation lie north
of our area over central and northern california. CPC outlook
does show a greater probability for above normal precipitation for
the state, including southern california, for the thanksgiving
holiday weekend. Right now, light amounts are favored here in the
south with higher amounts towards norcal.

Aviation
152100z... Gradually increasing high clouds around 20000 feet msl
with unrestricted vis through Friday morning. Light and variable
winds through the period.

Marine
No hazardous marine weather through Monday. Patchy dense fog is
possible, but not probable, in the coastal waters Friday morning.

Fire weather
The santa ana winds have weakened and will fade as winds turn
weakly onshore on Friday. Onshore winds will strengthen slightly on
Saturday. Critical relative humidity will continue through this evening
away from the coast. While humidity will moderate on Friday, minimum
relative humidity values in the teens are still forecast for part of
the inland valleys and across the mountains and deserts.

Weak offshore flow may return for inland areas for late Saturday
night into Sunday morning and late Sunday night into Monday
morning with gusty east to northeast winds mostly 30 mph or less
near the coastal slopes of the mountains and below passes and
canyons. The humidity for those areas could fall to around 15
percent at times, mainly during the late morning into the
afternoon on Sunday and Monday.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

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.
