Synopsis 22 853 am.

Temperatures will remain slightly below normal at the beginning of
the period with the passage of a weak upper level trough. Coastal
low clouds and fog will spread into coastal valleys tonight,
retreating to the coastal areas only this weekend. Building high
pressure next week will bump temperatures higher, returning to
normal and slightly above normal for next week.

Short term (tdy-sat) 22 957 am.

Gradients trending 1-3mb onshore today which should translate to a
few degrees of cooling in most areas and locally as much as 10-15
degrees where downsloping winds yesterday provided an additional
heating factor. Already seeing southeast winds increasing across
the coastal waters south of pt conception, a trend that will kick
in even stronger later tonight and push north along the central
coast Friday morning in what looks like a pretty impressive
southerly surge.

***from previous discussion***
synoptically, at the upper levels, a weak upper level trough will
remain over southern california with a strong upper high
developing over the eastern pac. By Friday, the upper level ridge
to the west will start to expand east and keep the upper level
trough well north across the pac NW through sat. At the lower
levels, onshore flow will increase today which will cause most
locations cool down 3-6 degrees from yesterday. There could be a
rogue 100 degree reading across the antelope valley this
afternoon, but most inland locations will remain in the upper 80s
and 90s. Coastal areas will be fairly mild. Yesterday, a few
central coast locations did heat up due to some downsloping
offshore winds in and around avila beach and port san luis.

Yesterday's high reached 94, but with an earlier seabreeze should
cool well down into the 70s or upper 60s.

Low clouds will be returning this evening across most coastal
areas. In fact a fairly strong catalina eddy is expected to
redevelop bringing some gusty SE winds across the socal bight and
adjacent coastal areas from l.A. To the sba south coast after
midnight. Low clouds should really deepen due to the strength of
the eddy and reach all coastal valley locations. Southerly winds
will continue most of the day on Friday. So even through h5
heights will be climbing slightly as the ridge builds in. However
strong southerly flow will keep high temps quite cool for coastal
areas and could keep low clouds hugging the beaches most of the
day. Expect additional 2-6 degrees of cooling for most areas
except up to 15 degrees of cooling across the san luis obispo
interior valleys due to the cooler southerly air mass. Paso robles
only expected to reach the mid 80s, but would not be surprised if
it only reached the lower 80s. One caveat to the southerly flow
will be some warming across the sba central coast near lompoc as
decent downsloping occurs across the santa ynez range. An opposite
effect to a sundowner. Highs in lompoc expected to reach the lower
80s.

By Saturday, an elongated upper level ridge from the eastern pac
to new mexico will dominate the weather pattern. Weaker onshore
flow is predicted and with building h5 heights and thickness
levels, high temps will be trending up anywhere from 2 to 10
degrees with highs reaching triple digits across the antelope
valley and back up to the mid to upper 90s across most valleys.

There will continue to be night through morning low clouds Friday
night into Saturday morning, with less areal coverage for valley
locations.

What is now tropical storm ivo located around 550 miles ssw of
cabo san lucas will start to shift to the north and move parallel
off the coast of central baja ca by Saturday. There will be no
affects from ivo through Saturday.

Long term (sun-wed) 22 325 am.

High pressure aloft will dominate the weather pattern through the
extended period (sun-wed). With onshore gradients expected to be
moderately strong, high temps overall will be a few degrees above
normal away from the coast with most valleys warming into the 90s
while the antelope valley should be around 100-103 degrees. Coastal
areas will remain mild with night through morning low clouds affecting
most coastal areas, and possibly the santa ynez valley.

As mentioned in the earlier discussion... Tropical storm ivo
(pronounced "eye-vo") will begin to track to the north and
maintain its tropical storm status but could become a weak
hurricane briefly Friday afternoon. As ivo continues to track
north parallel to baja cal, it will meet with cooler waters and
should weaken to a depression by early Monday morning. The strong
high pressure aloft to the NE over southern cal will keep the main
remnants from ivo well off the coast. In fact the latest gfs
model run keeps most of the mid to high level clouds off the coast
on Sun mon. Main impacts will be increasing southerly swells and
surf at south facing beaches. Read the "beach discussion" below
for more details.

Aviation 22 1737z.

At 17z, the marine layer was 1600 feet deep at klax. The top of
the inversion was around 2600 feet with a temp of 24c.

Bkn010 conditions possible at koxr and klax at times through 00z
today, especially if the west winds start. Moderate confidence in
cigs tonight becoming far more expansive than last night, with
higher bases. Bkn008-012 will be most common, except for possible
lifr at ksba ksmx ksbp kprb. Low confidence on timing of clouds
and winds. Moderate confidence in abnormally strong SE winds on
Friday.

Klax... 30 percent chance of bkn010 at times between 20-00z today.

High confidence in CIGS bkn006-10 forming by 03-07z tonight,
likely lifting above ovc010 by 08-12z. Quick clearing by 16z
Friday likely. Southeast winds likely 09-17z, with a 70 percent
chance of exceeding 10kt for several hours 12-16z.

Kbur... High confidence inVFR with typical winds through 06z. High
confidence in ifr MVFR cats forming by 07-10z.

Marine 22 907 am.

High confidence in small craft advisory (sca) winds through
tonight over the outer waters from the central coast to san
nicolas island. 50 percent chance of SCA winds for the nearshore
central coast waters. Moderate confidence for relatively light
winds well below SCA Friday through at least the weekend.

Choppy or steep seas expected over all coastal waters through at
least tonight due to the winds mentioned above.

Moderate confidence for abnormally strong southeast winds over
most coastal waters later tonight into early Friday afternoon,
focused from point conception to orange county. 10 to 15 kt will
be common, but local gusts between 15 and 25 kt are likely
around the channel islands and through the san pedro channel.

There is a 30 percent chance of reaching SCA criteria.

An abnormally large south to southeast swell from tropical storm
ivo will impact the waters Sunday through Tuesday. There is a
potential for the swell to peak between 5 and 7 feet. A swell
from this direction would cause strong surges around and inside
the vulnerable harbors, especially avalon and san pedro long
beach. Large breaking waves near the coast are also likely, which
has a history of capsizing small drifting boats.

Beaches 22 912 am.

Tropical storm "ivo", currently about 500 miles southwest of cabo
san lucas, will generate a southeasterly swell reaching
california Sunday and persisting through Tuesday. The peak of the
swell should occur Sunday afternoon through Monday morning with a
period around 14 seconds. While the peak swell heights will most
likely fall between 3 and 5 feet, there is a 20 percent chance
for a range of 5 and 7 feet.

Dangerous rip currents and large breaking waves on rock jetties
are certain. Surf heights should reach at least 4 to 6 feet over
south facing beaches, with a chance of peak surf reaching 6 to 8
feet especially for los angeles county, which would require a high
surf advisory.

There is a risk for impactful coastal flooding as well. The
highest tides will be late in the afternoon, and should reach a
modest 5.5 to 6.2 feet. If the peak swell ends up 3 to 5 feet,
flooding impacts would be minor and mainly in the form of beach
erosion. If the swell height ends up closer to 7 feet, more
impactful flooding would be expected for the vulnerable areas
like pebbly beach in avalon and the long beach peninsula if
unprotected.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect from 3 pm this afternoon to 9
pm pdt this evening for zone 645. (see laxmwwlox).

Small craft advisory in effect until 3 am pdt Friday for
zones 670-673. (see laxmwwlox).

Small craft advisory in effect until 9 pm pdt this evening
for zone 676. (see laxmwwlox).

Hazard potential outlook (sat-wed)
Elevated surf and strong rip currents are possible at area beaches
early next week.
