Synopsis
Fair and mild weather will continue this coming week, with
coastal clouds nights and mornings.

Discussion For extreme southwestern california including orange...

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

coastal low clouds struggled to get traction overnight and as a
result the Sun greeted most of us this morning. There was a slight
offshore trend in our pressure gradients that probably inhibited the
low cloud formation. Anyway, that's our explanation. Obviously today
will be sunny for most areas. The marine layer and onshore flow
should stabilize better for a more uniform coastal cloud deck
tonight, and clouds fog could reach into the westernmost inland
valleys. Copy and paste this idea for the coming seven days and your
forecast should be pretty accurate. The day to day fluctuations in
cloud coverage and temperature will be too subtle to notice unless
you're really paying attention. We are paying attention around here,
so we'll mention a very weak trough develops Sunday and Monday that
will probably push nocturnal coastal clouds a little farther inland
and bump temps downward a couple degrees. For the entire coming week
we see no credible hint from models about any monsoon flow. That
will mean mostly clear skies (except for the nocturnal coastal
clouds), along with dry and mild weather with temps a little under
august averages.

Aviation
161525z... Coast valleys... Areas of low clouds with bases around 1500
ft msl and tops to 2500 ft msl cover portions of orange county and
southern san diego county at this hour, impacting ksan and ksna.

Clearing to the coast is expected by 17z. Low clouds with bases near
1200 ft msl will return to the coast after 03z Friday, slowly
spreading inland about 20 miles by 12z fri. Impacts to kont and ksbd
are doubtful.

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

Marine
No hazardous marine weather is expected through Monday.

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.
