area forecast discussion... Updated
national weather service los angeles oxnard ca
838 pm pdt Sat aug 24 2019

Synopsis 24 837 pm.

High pressure dominating over the region will give way to mostly
sunny skies and warming temperatures through the week, especially
for inland areas. A shallow marine layer in place will allow night
through morning low clouds to likely stay confined over coastal
areas through Tuesday.

Short term (sat-tue) 24 812 pm.

***update***
update to the update: low clouds have rounded pt conception and
are moving into the sba channel so sba south coast will have low
clouds tonight and Sunday morning.

593 dm hgts overhead that extend from an upper high just to the nw
of the bay area. The onshore flow has weakened by a mb or two.

These two things along with a general lack of marine layer
stratus this morning contributed to a good warm up. Most areas
warmed 5 to 10 degrees today. Paso robles recovered from their 19
degree drop yesterday with a 18 degree warm up. Long beach warmed
14 degrees due to a late arriving and weak sea breeze. Most areas
away from the beaches were 3 to 6 degrees above normal.

Skies are clear right now and there is not much stratus lurking
offshore. The gradients are weaker. There is not much in the way
of winds in the outer waters to power start an eddy. Low clouds
will arrive late and might not arrive at all over some coastal
areas.

***from previous discussion***
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 24 816 pm.

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

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 tonight 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. Conditions are generally expected
to remain below SCA levels tonight through Thursday. The only
exception will be Thursday afternoon and evening when there is a
50% chance of SCA level winds across the western half of the
santa barbara channel.

Patchy dense fog with visibility of one nautical mile or less is
expected over the northern coastal waters late tonight through
Sunday morning due to a shallow marine layer. A marine weather
statement is currently in effect through mid morning on Sunday.

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).

Pz... None.

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