Synopsis
A weak low pressure system moving inland through southern
california will bring gusty west winds to the mountains and
deserts through this evening and a few light showers early this
morning... And again for late this morning through this afternoon.

Warmer and dry for Sunday... Then cooler and breezy for late Sunday
night and Monday as another weak low pressure system moves inland
through southern california. Dry with warming for Tuesday and
Wednesday... Then a little cooler toward the end of the week as a
low pressure system moves into the southwest states.

Discussion For extreme southwestern california including orange...

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

Short term (today through Monday)
A weak low pressure system is moving inland through southern
california early this morning. Light precipitation has moved
across southern california overnight with most of the light
measurable amounts from los angeles county westward with some
trace amounts possible over portions of orange and southwestern
san bernardino counties. Besides any light precipitation early
this morning... Widely scattered mostly light showers are expected
to spread southward across southwest california for late this
morning through this afternoon. High temperatures will cool to
around 5 degrees below average for today. Stronger onshore flow
will bring gusty west winds to the mountains and deserts into this
evening.

Dry and a little warmer for Sunday under weak high pressure...

then another weak low pressure system will move inland across
southern california late Sunday night and Monday bringing cooling
with high temperatures around 5 degrees below average. Gusty west
winds for the mountains and deserts are expected to be a little
stronger than today with precipitation chances less.

Long term (Tuesday through Friday)
For Tuesday... A low pressure system over arizona will bring gusty
north winds with high pressure aloft over northern california
bring a warming trend that will continue into Wednesday west of
the mountains and into Thursday for areas farther inland. This
will take high temperatures to around 5 degrees above average for
coastal areas... And 10 to 15 degrees average farther inland.

Around next Friday... Another low pressure system will move into
the southwest states. There remain differences among the global
models with the details and placement... But the trend of the past
24 hours has been to be farther inland... Such that a little
cooling with gusty north winds is possible on Friday... With
weakening winds and warming for next weekend.

Aviation
251000z... Scattered light showers will be possible over and west of
the mountains through this afternoon. Expect areas of low clouds
with bases 1500-3000 ft msl west of the mountains through this
afternoon. Vis could lower to 3-5 sm where showers develop, with vis
near zero where low clouds and terrain intersect.

West winds with gusts of 40-50 kt across mountain ridges will result
in mdt-strong up/downdrafts and llws this afternoon.

Marine
A low pressure trough moving across the region will create northwest
wind gusts near 20 kt, choppy seas, and isolated light showers at
times today. Northwest winds are expected to strengthen Sunday night
through Monday night as another system passes across the region.

Gusts to 25-30 kt are possible late Monday. The winds, combined seas
near 10 feet and steep waves, will result in hazardous conditions
for small craft on Monday. Conditions improve on Tuesday.

Beaches
West-northwest swells from around 285-290 degrees will create surf
of 3-6 feet Sunday through most of next week. This will be
accompanied by an increased risk of strong rip currents through the
period.

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.
