Synopsis for the far southern california coast.. At 1 am, a nearly neutral flow pattern over the coastal waters featured a 1019 mb low at the center of a coastal eddy circulation. The eddy will peak this morning then fade late today as offshore flow develops. Offshore flow will peak Thursday. Weak onshore flow returns Friday. Light and variable winds are expected through the weekend.

Synopsis
There will be some patchy coastal low clouds and some high clouds
early today. High pressure aloft and offshore flow will bring
warming west of the mountains for Thursday with locally gusty
northeast winds near the coastal slopes of the mountains. A little
cooler for Friday as onshore flow returns, then a little warmer
for the weekend under weak high pressure aloft. A low pressure
system will move inland through california on Monday with small
chances for precipitation, then dry for Tuesday with the
beginning of a warming trend.

Discussion For extreme southwestern california including orange...

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

Short term (today through Friday)
Aircraft soundings from Tuesday evening showed a weak marine
inversion at around 1400 feet with satellite imagery showing some
very patchy stratus over the inner coastal waters, and adjacent
coastal areas inland to the western san diego county valleys.

Satellite imagery also showed a few high clouds from a trough of
low pressure moving inland to the north. As that low pressure
system moves from the great basin into the southern rockies,
surface high pressure behind it over the great basin will bring
periods of gusty northeast to east winds for tonight into Thursday
along coastal mountain slopes into the inland valleys and below
passes and canyons. Onshore flow will return on Friday as another
trough of low pressure moves inland to the north.

High temperatures today will be similar to those of Tuesday with
warmer high temperatures west of the mountains on Thursday with
the offshore flow. Cooling will begin to spread inland on Friday
with a return of onshore flow.

Long term (Saturday through Tuesday)
The weekend is expected to be a little warmer for most areas as
onshore flow weakens, possibly becoming weakly offshore for
inland areas at times.

For Monday and Tuesday, the range of solutions among the global
models and their ensemble members has not changed much for the
weak low pressure system that will be in the vicinity of southern
california on Monday. The weaker and more inland solutions would
be mostly dry for southwest california, while the more amplified
solutions briefly close off an upper lower near or just offshore
of the california coast before moving it inland. Given that a
subtropical plume of moisture with precipitable water values
approaching one inch will be directed toward southern california,
there would be greater potential with this scenario for more
widespread precipitation. The intermediate scenario is one with a
cold front and associated precipitation weakening as it moves east
and south of point conception with light precipitation possibly
extending into portions of southwestern california for Monday
afternoon and evening. The current forecast remains closest to
that intermediate scenario.

Aviation
121000z... Areas of low clouds based around 1500-2500 feet msl will
continue to randomly form and dissipate in coastal areas and western
valleys this morning. Local vis 4-5sm with pockets of much lower vis
inland. Mostly clear after 16z. Patchy low clouds may redevelop
after 02z tonight, but confidence is low on timing and coverage.

Marine
No hazardous marine weather is expected through Sunday.

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

Sgx watches warnings advisories
Ca... None.

Pz... None.

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.
