459 pm pdt Sat aug 24 2019

Synopsis 24 757 am.

High pressure building over the next few days will allow for the near
normal temperatures today to warm on Sunday and remain warm into
next week. Night to morning coastal clouds will be less prominent
over the the next few days, becoming more widespread along the
coast into next week.

Short term (tdy-tue) 24 237 pm.

The marine inversion early this afternoon was near 700 ft deep at
lax. Low clouds were noted at some of the beaches along the central
coast early this afternoon, otherwise sunny skies prevailed across
the region which will continue thru the rest of the afternoon. Nam
forecast onshore gradients of +6.4 mb lax-dag late this afternoon
will promote locally gusty s-w winds across the foothills, mtns
and deserts.

Temps will be much warmer and are expected to top out a few
degrees above normal in the warmest vlys. Expected highs range
from the upper 60s to low 70s along the immediate coast, mid 70s
to mid 80s over the inland coastal plain, 90s to near 100 in the
vlys and lower mtns, and upper 90s to 102 in the antelope vly.

Through mon, the forecast area will be under the southern portion of
an elongated upper level ridge extending from off the NRN ca coast
thru central and sern ca into az. H5 heights over the forecast area
will be in the 593-595 dm range thru the period. There will be
generally weak SE flow aloft, but any monsoonal moisture will
continue to remain far to the E of the region. The upper ridging
will then weaken slightly Mon night and Tue as the remnant upper
level trof from tropical storm ivo moves off the ca coast.

The marine inversion will likely remain surface-based at vbg and 600-
800 ft deep or so at lax tonight thru mon, then deepen slightly mon
night into Tue morning. Low clouds and fog should affect the coastal
plain into the southern san gabriel vly tonight, and the central
coast along with the vtu l.A. County coast night and morning hours
from Sun night thru Tue morning. Patchy dense fog will be possible
with any low clouds tonight, and mainly along the central coast sun
and Mon nights. Otherwise, mostly clear skies will prevail tonight
thru tue, altho a few mid level clouds may move into the area from
the S Sun and Sun night.

Afternoon onshore gradients (lax-dag) are forecast by the NAM to be
around +6.7 mb sun, +7.2 mb mon, and +8.1 mb tue. These gradients
will continue to promote some gusty S to W winds each afternoon and
early evening across the foothills, mtns and deserts. In addition,
gradients from sba-smx will lower to as low as -2.0 mb Sun evening
and Mon evening, with mild sundowners possible along the sba s
coast and santa ynez mtns.

With decent warming in the boundary layer and 950 mb level, and high
1000-500 mb thicknesses (582-586 dm), temps away from the coast are
forecast to warm further Sun the Tue to about 4-10 deg above normal
away from the coastal plain. Highs each day for the warmest vlys and
lower mtns will be in the mid 90s to about 103.

As far as tropical storm ivo... As of 2 pm pdt, the center was about
425 miles W of the southern tip of baja california. Ivo will
continue to weaken as it continues to move nnw parallel to baja and
be downgraded to a tropical depression by late Sun morning as it
continues to move across cooler waters. The only affect for SRN ca
from ivo will be surf related. See the "beach discussion" below for
more details.

Long term (wed-sat) 24 239 pm.

The upper level ridging will build back into the area Wed and thu,
with a 594 dm high at h5 expected to be over SRN ca by late fri.

Upper level ridging will then persist over the region thru sat,
with h5 heights lowering slightly to 592-593 dm.

The marine inversion should increase slightly for Tue night and wed,
with night and morning low clouds and fog expected to expand to all
coastal areas and some adjacent vlys. The upper level ridging will
lower the marine inversion again to below 1000 ft deep late this
week resulting in reduced low cloud coverage. The central coast and
mainly l.A. County coast should have the night and morning low
clouds Thu night into Sat morning. Otherwise, mostly clear skies
will continue across the forecast area thru the extended period.

Temps will continue to be several degrees above normal away from the
immediate coast Wed thru sat. Highs in the warmest vlys and lower
mtns should be generally in the 90s to near 100 each day.

Aviation 24 2357z.

At 2315z at klax, the marine layer was 800 ft deep. The top of
the inversion was 2300 feet with a temperature of 28 c.

High confidence in 18z valley desert tafs.

Low confidence in coastal tafs. There is a 40 percent chc of no
cigs at any given site. If CIGS do arrive they could come in + - 2
hours from forecast time.

Klax... Low confidence in taf. There is a 40 percent chc of no
cigs. If CIGS do arrive it could be anytime between 10z-14z. There
is a 30 percent chc of ovc004 12z-15z. Very good confidence of no
east wind component.

Kbur... High confidence in cavu taf.

Marine 24 205 pm.

For the outer waters, moderate to high confidence in current
forecast. Today through Wednesday, high confidence in winds and
seas remaining below small craft advisory (sca) levels. On
Thursday, there is a 60% chance of SCA level winds developing.

For the inner waters north of point sal, moderate to high
confidence in current forecast. High confidence in winds and seas
remaining below SCA levels through Wednesday. On Thursday, there
is a 50% chance of SCA level winds during the afternoon and
evening hours.

For the inner waters south of point conception, moderate to high
confidence in current forecast. Today through Thursday, conditions
are generally expected to remain below SCA levels. The only
exception will be Thursday afternoon evening when there is a 50%
chance of SCA level winds across the wester half of the santa
barbara channel.

Patchy dense fog will impact the coastal waters the next couple of
days. Visibilities of one nautical mile or less will be possible
at times.

A large southeast to south swell from tropical storm ivo will
affect the waters Sunday through Tuesday. Swell will likely
peak between 3 and 5 feet, with a slight chance of swell peaking
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 24 205 pm.

Tropical storm ivo, currently about 350 nautical miles wsw of
cabo san lucas, will generate a southeasterly to southerly swell
which will reach the coastal waters california Sunday and persist
through Tuesday. The peak of the swell should occur Sunday
afternoon through Monday morning with a period around 12 seconds.

The peak of the swell heights will most likely fall between
3 and 5 feet, with a slight chance of swell heights reaching
5 to 7 feet.

Dangerous rip currents and large breaking waves on rock jetties
are certain. Surf heights should reach at least 3 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 of some coastal flooding as well. The highest
tides will be late in the afternoon, and should reach 5.7 to 6.7
feet. If the peak swell ends up between 4 and 5 feet as expected,
flooding impacts would be mostly minor and mainly in the form of
beach erosion and minor overflow. If the swell heights ends up in
the 5 to 7 foot range, which is much less likely, more impactful
flooding would be expected for vulnerable areas like pebbly beach
in avalon and unprotected parts of the long beach peninsula.

Lox watches warnings advisories
Ca... Beach hazards statement in effect from 2 am pdt Sunday
through Tuesday morning for zones 40-41-87. (see laxcfwlox).
