Synopsis
A deep marine layer and onshore flow will return low clouds along
and west of the mountains tonight. A weak trough will move across
the state on Saturday, enhancing the onshore flow, and maintaining
below average temperatures. There is a small chance for a few light
showers late Saturday or Sunday. A large west swell will generate
high surf this weekend as well. Dry and warmer early next week. A
larger storm system will impact northern and central california mid
next week, and may skim socal with periods of light rain then, with
a return of breezy and cooler weather.

Discussion For extreme southwestern california including orange...

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

skies were fair across the forecast area midday, except along some
of the coastal foothills of the mountains in san bernardino and
riverside counties where low clouds were holding fast. Surface
pressure gradients were weak and wind reports mostly light. A precip
summary has been posted on our website for the entire event over the
past couple of days and worth looking at the variability overall.

A weak ridge drifting over socal today will be east of the area on
Saturday as a weak trough moves east off the pacific. The incoming
trough will help to enhance onshore flow and build up the marine
layer a bit, possibly sparking more light, scattered showers along
and west of the mts by late Saturday. Sunday will be a bit warmer
with near average temps as the marine layer thins and the strong
march Sun warms the sfc under a weak transient ridge aloft.

An active storm track persists across the eastpac, thanks to
persistent ridging over alaska. Another deep, cold low will develop
in this flow off the pacnw coast early next week and drive more rain
and snow across northern and central ca. Some of this energy could
brush southern parts of the state late Wed Thu when low pops are in
the forecast west of the mts, but it doesn't look too promising at
this point.

Operational model run discrepancies between the GFS and ECMWF become
quite large toward the end of the forecast period so not much
confidence in the weather for next weekend. It does put us at the
end of march though, so if we have to choose between lamb and lion,
it would be the lamb at this point.

Aviation
222000z... Coasts valleys... Sct to locally bkn clouds with bases 2500-
4000 ft msl continuing through the afternoon. Bkn-ovc stratus will
develop after 23 03z and spread inland with bases 1500-2500 ft msl
and tops to 3500 ft msl. Clouds becoming sct with bases mostly above
3000 ft msl late Saturday morning.

Mountains deserts... . Few-sct clouds AOA 20000 ft msl and
unrestricted vis through Saturday afternoon.

Marine
A large west-northwest swell with a 15-17 second period could bring
combined seas to 9 feet in the outer waters on Sunday. Otherwise, no
hazardous marine weather is expected through Tuesday.

Beaches
A west-northwest swell of 7-9 feet from 290 degrees with a 15-17
second period will likely generate high surf late Saturday night and
Sunday, mainly in san diego county. A high surf advisory has been
issued for orange and san diego counties from 2 pm Saturday through
9 pm Sunday.

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

Sgx watches warnings advisories

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.
