221 pm pdt Fri aug 23 2019

Synopsis 23 1250 pm.

Low clouds continue to linger over the central coast this
afternoon, otherwise sunshine will be abundant across the area
through the afternoon. High pressure will build in this weekend
allowing for a warming trend through at least early next week,
mainly away from the coast. Night through morning low clouds and
fog are expected to stay confined to coastal areas.

Short term (tdy-mon) 23 212 pm.

A deeper than usual marine layer (2000-2500') and fairly strong
southeast flow combined to bring cooling to many areas today,
especially the valleys which were down by 5-10 degrees on
average. High pressure is expected to start building over the area
Saturday with weakening onshore flow. This will start a warming
trend that will continue into early next week. The marine layer
will likely shrink tonight but still push into the valleys. A more
traditional clearing pattern is expected Saturday as the
southerly flow today shifts back to a westerly flow. Biggest warm
up will be in the valleys but most coastal areas will warm at
least a couple degrees.

The high peaks in strength Sunday and Monday, but with onshore
trends expected Monday coastal areas may cool a degree or two
while inland areas continue to warm. Warmer valley highs should
top out around 100 while antelope valley temps approach 105 in the
warmest locations. Marine layer will be shallow but solid along
the coast during the night and morning hours. Most areas should
clear by afternoon but some clouds may linger at the beaches into
the afternoon, especially Monday with the onshore trends.

As for ivo, the forecast track shifted a little farther east but
it's not strengthening as much as earlier expected and models
still just showing minimal higher level moisture skirting the
western portion of the forecast area. So will keep a few clouds in
the forecast for that but otherwise the main impacts of ivo will
likely be increasing surf on south facing beaches. See beaches
discussion below for more details.

Long term (tue-fri) 23 220 pm.

High pressure will be the primary driver of our weather next week,
keeping temps at or slightly above seasonal norms. Models do show
the high weakening slightly as the remnants of ivo get pulled into
westerlies and ride up and over the ridge. This will knock
heights thicknesses down slightly tue-wed before the ridge
rebuilds later in the week and temps nudge upward again. Marine
layer clouds will remain along the coast during the night and
morning hours, otherwise skies will generally be clear.

Aviation 23 1724z.

At 1715z, the marine inversion at klax was based at 2800 feet.

The top of the inversion was 5400 feet with a temperature of
22 degrees celsius.

Overall, low to moderate confidence in 18z coastal and valley tafs
and high confidence in desert tafs. Current MVFR ifr are expected
to dissipate this afternoon although there is a 40% chance of MVFR
cigs remaining at ksba. For tonight, high confidence in return of
stratus to coastal valley sites, but low confidence in timing or
flight category.

Klax... Overall, moderate confidence in 18z taf. There is a 30%
chance that MVFR will not dissipate until 21z. For tonight, high
confidence in return of MVFR cigs, but low confidence in timing
(could be + - 3 hours of current 05z forecast).

Kbur... Overall, moderate confidence in 18z taf. High confidence in
vfr conditions through this evening. For tonight, high confidence
in return of stratus, but low confidence in timing (could be + -
3 hours of current 08z forecast) and flight category (50% chance
that CIGS will return at MVFR levels).

Marine 23 212 pm.

For all the coastal waters, high confidence in current forecast.

Today through Wednesday, winds and seas are expected to remain
below small craft advisory (sca) levels.

An abnormally large southeast to south 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 23 212 pm.

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 4 and 6 feet, there is a 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
5.7 to 6.7 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 8 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... Beach hazards statement in effect from late Saturday night
through Tuesday morning for zones 40-41-87. (see laxcfwlox).

Pz... None.

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