Synopsis
Mostly sunny skies with near normal temperatures will prevail the
rest of today. Moisture from the southeast will increase Thursday
and should produce some clouds in the deserts and desert mountain
slopes then. Areas of low clouds and fog will occur near the coast
during most nights. Temperatures will increase a little bit
Thursday, with slightly above normal temperatures through the middle
of next week.

Discussion For extreme southwestern california including orange...

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

sunny skies prevailed at early afternoon, with temperatures mostly 2
to 4 degrees lower than on Tuesday and near seasonal normals.

The upper trough will lift to the northeast tonight and Thursday,
with weaker short wave moving into mainly central california. While
westerly flow above 700 mb will continue to keep dry air aloft over
california, some low-level southeast flow, associated with tropical
depression 19-e in the gulf of california, will bring humidity into
the deserts and most of the mountain areas, and this will likely
bring a period of stratus early Thursday to the deserts and desert
mountain slopes with even some fog on the desert mountain slopes,
mainly san diego riverside counties. The moisture will probably not
be sufficient for thunderstorms, isolated light showers are not out
of the question Thursday. The southeast low level flow could spill
over the mountains and result in some east flow on the west slopes,
with local gusts around or just over 25 mph possible there Thursday
morning. That, in combination with increased pressure
heights temperatures aloft should result in some decrease in the
areal coverage of the coastal night and morning low clouds.

Temperatures will accordingly be higher Thursday west of the
mountains, though higher humidity will likely lower temperatures in
the deserts by around 5 degrees. That extra humidity will linger for
awhile with a slight decrease each day through early next week. A
ridge of high pressure building over the interior southwest and the
jet stream and troughing staying well to our north will mean that
temperatures will be a little above normal through probably at least
through the middle of next week. There is still a chance of some
offshore surface flow around next Wednesday.

Aviation
172030z... Coast valleys... Coastal low clouds will redevelop after
05z and spreading 10-15 miles inland overnight. Bases will be around
1000-1500 ft msl with tops to 1800 ft msl. Local vis 3-5 miles
possible in higher terrain. Clearing in the inland valleys on
Thursday 10-15z and on the coast 16-18z.

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

Marine
A coastal eddy will develop tonight offshore and result in light
southerly flow through Friday night. No hazardous weather is
expected through Monday.

Fire weather
Areas of very low humidity, in some places less than 5 percent, will
continue this afternoon in the mountains and deserts, though it will
gradually rise later this afternoon in parts of the deserts. More
significant increases will occur late tonight and Thursday morning
due to moisture from the southeast. Winds will be lighter this
afternoon, with only local gusts over 30 mph through san gorgonio
pass and around 30 mph in the san diego county deserts. Some
offshore flow from the east could occur Thursday morning on the west
mountain slopes, mainly san diego and riverside county, with local
gusts over 25 mph, but humidity will be increasing then.

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.
