Synopsis
An upper-level trough will weaken through Saturday for minor
warming and a shallower marine layer. An upper-level low will
develop off the southern california coast early next week for
cooler weather and a deeper marine layer yet again.

Discussion For extreme southwestern california including orange...

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

at 3 am pdt, water vapor satellite imagery displayed an upper-
level trough over southern ca, and an upper-level ridge around 500
miles west of eureka. Fog satellite showed stratus struggling to
develop along the coast. Heights building over the region will
create a more shallow marine layer over the coast and valleys, and
increase high temperatures to just below normal through Saturday.

Next week, an upper-level low developing off the coast will help
to yet again create a deep marine layer, with night morning low
clouds and fog pushing well inland each day. This will also help
keep high temperatures around 5 degrees f below seasonal normals.

Onshore flow will continue into next week, with breezy west to
southwest winds developing each afternoon evening through mountain
passes and along desert mountain slopes.

Monsoonal thunderstorms are not expected through the period at
this time. Areas along the coast may have trouble viewing the
solar eclipse on Monday due to possible marine layer clouds. Models
are in fairly good agreement with the pattern through the next
week.

Aviation
160900z... Coast valleys... Areas of low clouds with bases around 1500
ft msl will continue to develop withing 20 miles of the coast
through 14z. Bkn ceilings are possible at ksan, kcrq, and ksna, but
not anticipated at kont. Local visibility restrictions of 3 sm or
less will occur near higher coastal terrain. Rapid clearing to the
coast is expected between 15z and 17z. Skc and light afternoon sea
breezes will prevail between 17z Thursday and 03z Friday. Low clouds
with bases near 1200 ft msl will return slowly to areas within 20
miles of the coast after 03z Friday.

Mountains deserts... Clear skies and unrestricted visibility will
prevail through Friday morning.

Marine
No hazardous marine weather is expected through Monday.

Beaches
A building moderate period south swell (2-3 ft at 200 degrees) will
arrive in the coastal waters Friday and continue through the
weekend. This swell may bring elevated surf (4-6 ft) and strong rip
currents to the beaches Friday through Sunday. No products are being
issued at this time, however a beach hazard statement may be
necessary at a later time.

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

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
