Synopsis
Fair, dry and seasonal weather is expected this coming week.

Areas of coastal clouds will continue nights and mornings.

Discussion For extreme southwestern california including orange...

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

coastal clouds actually gained some traction this morning. Most of
the coastal and western valleys of san diego county are covered,
and the move northward into orange county has begun. A weak trough
of low pressure will move through the west today and our marine
layer has already responded with better cloud development. Today
through Thursday some tropical monsoon flow will come northward
out of mexico. A soggy gulf surge will push into the lower
deserts and even some increase in humidity will be felt in the
mountains. This push will squeeze through the mountains and
actually create some easterly breezes Thursday morning in the
foothills. While we don't expect any showers or thunderstorms,
there should be some low stratocumulus clouds in the desert and
cumulus clouds in the mountains. That humid flow will continue to
a lesser degree Friday, so we expect fewer clouds. After today,
coastal clouds in our marine layer will have less coverage in time
and space this coming week, only areas near the coast late nights
and early mornings. The weather pattern will be quite nondescript
for a few days, with neither a trough or a ridge in place.

Temperatures trends will be really flat with no discernible trend
and quite close to seasonal averages. High pressure aloft builds
a little this weekend and next week so daytime temps should go up
a few degrees. The equinox on Saturday marks a transition to a
more fall-like weather pattern, with the jet stream driving some
troughs through the northern part of the country. That
occasionally results in some offshore flow for southern
california. It looks like we could get a weak offshore push
around the middle of next week that would bring some light
northeast winds, but mostly warm and dry air and less nocturnal
coastal cloudiness.

Aviation
190900z... Coast valleys... Stratus with bases 1400-1700 ft msl and
tops to 2000 ft msl will continue to fill in along the coast and
spread 15-20 mi inland this morning. Local vis 3-5 sm possible in
the inland valleys 10-15z. Stratus clearing to the coast 15-18z,
then redeveloping after 20 05z and spreading 10-15 mi inland
overnight. Bases will be near 1000-1500 ft msl.

Mountains deserts... Clear skies with unrestricted visibility through
this evening. There is a small chance of stratus development over
portions of the low deserts and adjacent desert mountain slopes late
tonight into Thursday morning as shallow moisture moves in from the
southeast. If stratus does develop, vis could be reduced to 5 sm or
less.

Marine
No hazardous marine weather is expected through Sunday.

Fire weather
Winds will decrease today while humidity gradually increases today
into Thursday. Relative humidity will continue extremely low in
the higher mountains today.

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

Ca... None.

Pz... None.

Public fire weather... Mm

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.
