734 pm pdt Fri aug 23 2019

Synopsis 23 728 pm.

Near normal temperatures Saturday will warm into above normal
values Sunday as high pressure builds over the region. These warm
temperatures will persist into next week. Expect low clouds and
areas of fog from the night to morning hours in many coastal areas
and some valleys through the period.

Short term (fri-mon) 23 703 pm.

***update***
skies were fairly slow to clear today but by mid afternoon there
was complete clearing and now it looks like the low clouds will be
slow to return due to a lack of or at least a slow to form eddy.

There were some easterly offshore trends today and that allowed
the coasts to warm a degree or two but away from the coast the
deeper marine layer and lowering hgts combined to knock 3 to 7
degrees off of the readings from yesterday with the major
exception of the interior slo vlys which saw 15 to 20 degrees of
cooling.

Forecast is in good shape but will issue an update to remove
clouds from santa clarita vly and trim back from the vlys near the
vta la county line,
***from previous discussion***
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 24 0050z.

At 2345z at klax, the marine layer was 1400 ft deep. The top of
the inversion was 3600 feet with a temperature of 24 c.

High confidence in kpmd and kwjf tafs.

Low confidence in remainder of tafs. Low cloud arrival time could
be off by as much as 3 hours and there is a 20 percent chc of no
low clouds at any given site. Sites with MVFR CIGS fcst have a 30
percent chc of ifr cigs. Clearing time could be off by + - 2
hours.

Klax... Low confidence in taf. Low cloud arrival time could be
anytime between 07z and 11z. There is a 20 percent chc of no low
clouds at all.VFR transition could occur any time between 15z and
19z. Good confidence that there will be no east wind component
greater than 3 kt.

Kbur... Low confidence in taf. Low cloud arrival time could be
anytime between 09z and 13z. There is a 30 percent chc of no low
clouds at all.VFR transition could occur any time between 15z and
17z.

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.
