pleasant day Sunday with some increasing clouds from the northwest
through the afternoon.
Next system for Sunday night and Monday is a little stronger and
chances are high that at least SB/SLO Counties will get rain from
it as the trough digs south much farther than tonight's system.
While there is some southerly flow out ahead of it Sunday
afternoon and night, by the time the front arrives it's mostly
with westerly flow and that will significantly weaken it as it
rounds Pt Conception. So while chances still look favorable for at
least some rain down to Ventura and even LA Counties any amounts
will be really light. Northern areas could see a half inch to as
much as an inch in the SLO coastal hills but south of SB amounts
will drop off to a quarter inch or less.
.LONG TERM (TUE-FRI)...14/125 PM.
Models still advertising a building ridge over California most of
next week with some light to occasionally moderate offshore flow,
especially Wed/Thu. Those look to be the warmest days with the
strongest offshore gradients and warmest air mass. If current
model solutions hold temps will likely climb into the lower 80s
many coast/valley locations in LA/Ventura Counties and 70s
elsewhere. It appears to be more of a northerly gradient as
opposed to northeast but either way it should be warm and dry
across the area with some gusty north to northeast winds at
times. Gradients expected to start trending onshore Friday with a
few degrees of cooling but still well above normal.

.AVIATION...14/1759Z.
At 1730Z...there was no marine inversion present at KLAX.
Generally hi confidence in the 18Z TAFs, except moderate confidence
at best for KPRB, KSBP and KSMX due to MVFR cigs expected at times
mainly this afternoon through late tonight except thru mid morning
Sat at KPRB. The timing of the onset and clearing of the low clouds
may be off +/- 1 to 2 hours and may be intermittent at best.
Otherwise, VFR conditions can be expected at the airfields through
Sat morning.
KLAX...Hi confidence in the 18Z TAF with VFR conditions expected
thru Sat afternoon.
KBUR...Hi confidence in the 18Z TAF with VFR conditions expected
thru Sat morning.

.MARINE...14/1211 PM.
Moderate-to-high confidence in the current forecast. A moderately
large northwest swell across the coastal waters will persist
through Saturday night. This swell will diminish some Sunday.
Hazardous seas will likely persist for periods of time across
outer and northern coastal waters through Saturday night. Between
Sunday night and Tuesday, a very large swell is expected to build
into the coastal waters and affect west to northwest facing
harbors, including Morro Bay. Ventura Harbor could also be
affected on Monday through at least Tuesday as some of the energy
from the swell filters into the Southern California Bight.
Moderate-to-high west to northwest swell will then persist through
Wednesday.
Otherwise, winds should remain below Small Craft Advisory (SCA)
levels through Tue except for a 50% chance of SCA level gusts at
times for the southern two outer waters zones (PZZ673 and PZZ676)
for Mon night through Tue.

.BEACHES...14/1215 PM.
An extended period of high surf continues to be likely at Central
Coast beaches through the middle of next week. There is a 60
percent chance of very large and potentially damaging surf
developing between Sunday night and Monday. The latest swell
models build a west-northwest swell to between 18-21 feet off the
central California coast with periods between 19 and 21 seconds.
Swell energy could possibly push into Southern California Bight
between Sunday and Monday with westerly swells building to as high
as 8 to 11 feet in the east Santa Barbara Channel.
If these swells develop as the computer models are forecasting,
surf of 18-23 feet with local sets up to 28 feet will be possible
at west and northwest facing beaches along the Central Coast
between Sunday night and Tuesday. There is a high probability that
the High Surf Advisory for the Central Coast will be upgraded to
a High Surf Warning to cover the surf over 20 feet Sunday night
through at least Monday. South of Point Conception, west facing
shores could potentially see surf between 8-12 feet with local
sets to 15 feet.
