Synopsis
A weak trough will deepen the marine layer tonight for more
extensive low clouds west of the mountains. High pressure building
aloft on Sunday will bring warmer days through Monday. Cooler again
midweek as a pacific trough moves inland across central california.

The system may generate a few showers over southern california, but
amounts will be light. Increasing onshore flow will bring a return
of cooler weather and gusty winds in the mountains and deserts. The
weather continues to look uncertain for the end of next week, but
largely dry.

Discussion For extreme southwestern california including orange...

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

highs today were remarkably similar to yesterday at nearly all
reporting coastal, valley and mountain stations. Fullerton (67),
newport beach (62), ontario (69), corona (66), rancho bernardo (64)
and idyllwild (54) were all the same as yesterday. Fifteen other
stations were within 1 degree of yesterday.

Low clouds were expanding over the inland basin and the foothills
this evening. Cloud bases were 1,500 feet with tops around 3,000
feet. A weak trough passing by over san bernardino county may
generate a shower or two tonight over the mtn slopes, but chances
are small.

Sunday will be 4 to 8 degrees warmer than today as high pressure
aloft increases 500 mb heights by 30 decameters. The exception to
this degree of warming will be in the coastal areas where the
proximity to 60 degree ocean water temperatures and the afternoon
sea breeze will limit warming to only a couple degrees. Monday will
be even warmer as heights rise another 20-30 decameters.

*from previous discussion*
it will remain mild on Tuesday as high clouds thicken ahead of a
stronger eastpac storm for midweek. This one will bring significant
rain snow to central and northern ca, and may brush socal with some
light showers as well but pops are low this far south and any
amounts are expected to be light.

The outlook remains rather murky for the latter half of next week
and into the weekend. The 12z operational runs of the ECMWF and gfs
remain out of phase across the west. GFS operational runs have been
more consistent with it's ensemble mean, while the ECMWF operational
runs have deviated more from it's ensemble mean. So, if there is a
model to favor around the end of next week, the GFS would be a
slight favorite. It appears as though the GFS model runs are holding
onto the goa ridge better than the ECMWF a swell, which may be the
way to go, keeping the energy in the westerlies directed over more
southern latitudes. Favoring the GFS would keep it much cooler but,
like the ecmwf, largely dry.

Aviation
230300z... Bkn-ovc stratus with bases 1200-1800 ft msl and tops to
3000 ft msl will affect the terminals through 24 15z, after which
bases will rise with most terminals clearing to few-sct near 2500 ft
msl by 17-18z. Areas of vis 3-5 sm on obscured coastal slopes and
mesas overnight with isolated spots to 1 sm or less, though
terminals should remain unaffected. Sct-bkn high clouds AOA 20000 ft
msl tonight, gradually clearing tomorrow leading to mostly clr skies
by the afternoon.

Mountains deserts... Bkn-ovc low clouds will obscure mountain slopes
overnight with local vis 3-5 sm through 16z. Winds will gradually
subside overnight, however isolated sfc gusts to 30 kts will be
possible, along with lgt-mod uddfts over and east of the mtns.

Deserts will remain clr minus few-sct high clouds AOA 20000 ft msl
overnight. Expect weaker sfc winds in valleys tomorrow, with gusts
below 15 kts.

Marine
Long-period 16 second swell will continue to bring combined seas to
8-9 ft in the outer waters overnight and into tomorrow. The swell
will begin to subside in the afternoon. Otherwise, no hazardous
marine weather is expected through Thursday.

Beaches
A west-northwest swell of 6-8 ft from 290 degrees, combined with a
15-17 second period could generate high surf through tomorrow with
sets to 8 ft possible, mainly in southern san diego county. A high
surf advisory is in effect for orange and san diego counties through
9 pm Sunday. &&

Skywarn
Skywarn activation will not be needed this weekend.

Sgx watches warnings advisories
