1037 pm pdt Thu aug 22 2019

Synopsis 22 820 pm.

Normal to below normal temperatures are expected for Friday,
before the area warms to above normal values for the weekend.

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 (thu-sun) 22 813 pm.

***update***
the marine inversion early this evening ranged from about 1400 ft
deep at vbg to about 1900 ft deep at lax. Low clouds have expanded
rapidly along the coast this evening and will continue to expand
overnight along the coast and into the adjacent vlys as a large
eddy cranks up over the socal bight and the marine inversion
deepens some more. Would not be surprised to see patchy drizzle as
well for the coast vlys of vtu l.A. Counties later tonight.

Otherwise and elsewhere, mostly clear skies can be expected thru
the night.

***from previous discussion***
the forecast through the weekend remains largely intact. The
marine layer is expected to deepen up to at least 2500' tonight
south of pt conception and at least 1500' up north. This will push
low clouds well into the coastal valleys later tonight and lower
high temps Friday by another 3-6 degrees on average, though as
much as 10-15 degrees across interior slo county. Low confidence
on the marine layer clearing pattern tomorrow given the big
southerly surge and continuing southeast flow just off the
surface. Theoretically this should help la and ventura counties
clear out while clouds struggle to clear across coastal slo sb
counties but confidence not high on this part of the forecast.

A weak eddy circulation is expected to continue into Saturday,
however building high pressure aloft along with weakening onshore
flow is expected to lower the marine layer depth and warm temps by
4-8 degrees, mostly across the valleys and other inland areas.

Marine layer clouds will likely linger at many beaches from malibu
west but otherwise skies will be sunny.

Slightly warmer again Sunday with better coastal clearing. Warmer
valley areas may be getting close to 100 again. May start seeing
some high clouds drifting over the area from the remnants of ivo
but models still not showing any lower level moisture as the
clockwise flow around the high over california steers the system
and it's moisture farther to the west so convective chances at
this point remain very low.

Long term (mon-thu) 22 213 pm.

While there will be subtle changes in gradients and the upper
level pattern next week the weather through the middle of next
week is not expected to change much. The GFS and ECMWF continue
to show the remnants of ivo riding up and over the ridge and
mostly into northern california Wed Thu so will have to keep an
eye on this but none of the ensembles are showing any precip so
dry and warm weather expected to continue with highs 2-4 degrees
above normal on average.

Aviation 23 0537z.

At 0430z, the marine layer was 2100 feet deep at klax. The top of
the inversion was around 4300 feet with a temp of 234c.

Widespread low clouds expected to push into all coastal and valley
areas overnight with the exception of the far interior valleys of
slo county and the cuyama valley. There is a slight chance that a
strong eddy circulation will move westward off the coast of l.A.

County pulling the clouds out of l.A. County. Otherwise, if this
does not occur, expect rather slow clearing on fri, by late
morning in the valleys and early to mid afternoon near the coast.

Cigs will generally rise overnight into the MVFR category, but
will remain ifr to lifr for most of the night north of pt
conception.

Klax... Moderate confidence in the 06z taf. CIGS will likely
scatter out for a few hours this evening. There is a 30% chance
that CIGS will not return until at least 14z. Here is a 30% chance
that CIGS will not return Fri evening until after 07z. There is a
20% chance of east winds gusting to 15 knots between 11z and 18z.

There is a 20% chance that east winds will persist through 21z.

Kbur... Moderate confidence overall in the 06z taf. While cigs
should arrive by 08z, they may be temporary, and there is a 30%
chance that more permanent CIGS will not arrive until 14z fri.

Marine 22 808 pm.

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

Moderate confidence for abnormally strong southeast winds over
most coastal waters later tonight into early Friday afternoon.

While 10 to 15 kt will be most common, peak winds between 15 and
25 kt are likely between point conception and orange county at
times. There is a 50 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 22 808 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... Small craft advisory in effect from 6 am to noon pdt Friday
for zones 650-655. (see laxmwwlox).

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

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