Synopsis for the far southern california coast.. At 2 am, a 1015 mb high was 100 nm northwest of san francisco, and a 1002 mb low was near needles. Instability and moisture associated with a weak wave moving up from the south will bring a slight chance of Thunderstorms this morning, mainly over the outer coastal waters. Weak onshore flow will continue today but strengthen Sunday through Tuesday when winds over parts of the outer coastal waters could gust to around 20-25 kt each afternoon and evening. Weak onshore flow will return Wednesday.

Synopsis
Strong high pressure will continue to bring hot weather to the
southern california interior while the marine layer will dominate
near the coast. There will be a slight warming trend and less
extensive coastal cloudiness for the weekend. Cooler weather and
more extensive coastal clouds are forecast next week.

Discussion For extreme southwestern california including orange...

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

the weather and the temperatures today were overall very much the
same as they were yesterday. And just like yesterday the top hot
spots were palm springs and 29 palms, each coming in at 114
degrees. One noticeable difference was the high altocumulus clouds
that floated in from the south this afternoon and evening. A few
of the cloud cells produced lightning off the baja california
coast and a sprinkle around tijuana. These cells will continue
their journey northwest toward santa barbara tonight and Saturday
morning before disappearing. They have disrupted (ripped a few
holes) in the continuous stratus cloud deck over the ocean and
orange county. They also added some texture to our sunset this
evening and will do the same for our sunrise Saturday morning.

These clouds and elevated showers and thunderstorms are part of a
weak shortwave moving north along the east side of a weak low
pressure trough to the west. This has put a dent in our strong
high pressure ridge still anchored over arizona sonora. We still
expect the ridge to expand slightly for some serious inland heat
this weekend, although the shortwave and early morning gulf surges
in the lower desert might temper the heat by a few degrees. As
the high pressure pushes down the marine layer this weekend, the
marine layer will shallow a bit tonight and a bit more Saturday
and Sunday nights. That will mean the coastal clouds will be
confined to the coastal areas and the brutally strong marine
inversion will ensure not much if any clearing at the beaches.

The low pressure trough migrates north riding the top of the
ridge and flattens it out next week. It could be enough of a
breakdown to return temperatures back to normal. It would also
deepen the marine layer and extend coastal clouds farther inland
nights and mornings.

Aviation
240400z... Coast valleys... Stratus will be less widespread tonight
and somewhat more patchy in some areas. While bkn ovc stratus has
reached ksan kcrq and likely will remain all night, ksna and most of
coastal orange county could have delayed arrival of stratus cigs,
possibly 07z-10z. Kont is unlikely to have stratus through Saturday
morning. Bases will be 800-1300 ft msl with tops to 1800 ft msl.

Local vis below 3 miles will occur in some valleys, including vcnty
krnm, mainly 09z-16z sat. Better clearing is expected sat, with most
coastal areas clearing 17z-19z and some stratus returning there sat
evening. Otherwise, mostly bkn clouds at above 15000 ft msl will
prevail through Saturday evening.

Mountains deserts... Mostly bkn clouds at above 15000 ft msl with
unrestricted vis will prevail through Saturday evening.

Marine
A disturbance from the south with moisture and instability aloft
will bring a slight chance of thunderstorms to the coastal waters
late tonight and Saturday morning. The best chance will be in the
outer coastal waters, beyond 30 miles from the coast. Cloud-to-water
lightning will be the biggest hazard, but brief local gusty wind and
resultant choppy seas could also occur. Little or no rainfall will
occur as the moisture will be limited and aloft. The thunderstorm
threat will diminish Saturday afternoon.

Northwest wind gusts over the outer waters may reach 25 kt during
the afternoons and evenings Sunday through Tuesday, potentially
resulting in conditions hazardous to small craft.

Beaches
A south swell of 3 ft 13-14 seconds 165-170 degrees combined with
large tidal swings will result in strong and dangerous rip and
longshore currents through this evening. This swell will also
produce surf of 3 to 6 ft at orange county beaches and san diego
county beaches north of carlsbad. High tides will reach 7+ ft during
the evenings through Saturday. Tides this high may result in minor
tidal overflow at low lying beaches. The beach hazards statement
continues through late Saturday evening. High tide will fall below 7
feet Sunday, lowering the tidal overflow threat.

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

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
