Synopsis
Today will be cool with scattered low clouds west of the mountains.

A large west swell will generate elevated surf through Sunday.

Warmer Sunday and Monday, then cooler again midweek as a low
pressure trough moves across the state. As onshore flow increases,
the marine layer will deepen, and there will be a chance for
scattered showers along and west of the mountains.

Discussion For extreme southwestern california including orange...

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

areas of low clouds covered large portions of the forecast area this
morning, while the mountains, deserts, and coastal areas from
southern orange county south, enjoyed a mostly clear skies. Farther
to the north a solid sw-ne band of clouds was advancing over point
conception. This marks a cold front that will drop SE and weaken
through this evening. The 12z miramar sounding showed a pronounced
warming below 6k ft beneath w-nw flow aloft. No low-level inversion
was evident due to the warming, suggesting our marine layer has
lowered considerably from yesterday. There has been a slight
increase in the onshore sfc pressure gradients (ksan to the
deserts). Wind reports were mostly light with a few gusts over 25
mph in the mts as of 8 am pst.

Expect a partly cloudy day along and west of the mts today as the
marine layer rebuilds ahead of the weakening cold front. There
could still be a few showers breaking out along the coastal slopes
and foothills this evening, but most areas will experience dry
weather through the weekend.

A weak trough will be moving over the state later today increasing
the onshore flow a bit and temporarily building the marine layer. A
weak ridge will follow on Sunday, allowing some warming and a
lowering of the marine layer through early next week. Daytime
temperatures will increase on sun, and should be about average
mon tue, then cooler midweek as a deeper trough moves onshore from
the eastpac. This one will bring significant rain snow to central
and northern ca, and may brush socal with some light showers as well.

The outlook gets rather murky for the latter half of next week and
into the weekend with the ECMWF gfs operational runs almost
completely out of phase. This is more of a temp wind issue than
precip though. Both suggest it will be dry.

Aviation
231535z... Coasts valleys... Sct-bkn low clouds will with bases 1500-
2500 ft msl and tops to 3500 ft msl will continue through 17z with
mostly unrestricted vis. Best chances for cig impacts at ksna, kcrq
and ksbd. After 17z, sct conditions will prevail with bases 2500-
3000 ft msl as well as high clouds at above 20000 ft msl. Areas of
bkn-ovc clouds will likely return between 02z and 06z tonight with
bases 1500-2500 ft msl again.

Mountains deserts... .Areas of bkn-ovc low clouds will continue over
the coastal mountain slopes with local terrain obscurations through
17z becoming sct-bkn after 17z with tops to 5000 ft msl. Otherwise,
sct-bkn clouds will occur at above 15000 ft msl through tonight.

Local west winds 15-25 knots with gusts to 35 knots will bring weak-
mdt up downdrafts over and east of the mountains this afternoon and
tonight.

Marine
A large west-northwest swell with a 15-17 second period could bring
combined seas to 9 ft in the outer waters on Sunday. Otherwise, no
hazardous marine weather is expected through Wednesday.

Beaches
A west-northwest swell of 7-9 ft from 290 degrees in the outer
waters, with a 15-17 second period will likely generate high surf
starting late this afternoon and peaking Sunday with sets to 8 ft
possible, mainly in san diego county. A high surf advisory has been
issued for orange and san diego counties from 2 pm Saturday through
9 pm Sunday.

Skywarn activation will not be needed this weekend.
