Synopsis 24 258 am.

High pressure building over the next few days will allow for near normal
high temperatures today then gradually trend higher through the weekend
into early next week. Expect night through morning low clouds and patchy
fog across coastal areas and santa ynez valley through early next week.

There is a lower chance that some stratus could move into some coastal
valleys across los angeles and ventura counties.

Short term (tdy-mon) 24 258 am.

Quite a difference from yesterday at this time when low clouds
were covering all coast and valleys. In fact yesterday's high at
paso robles only reached 79 which tied the lowest high
temperature for that date. Overall is was cooler than normal for
this time of year. However, today will high temps trend 3-10
degrees warmer.

Latest fog product imagery indicated clear skies for areas N of
point conception. To the south, only random patchy low clouds were
developing along some beaches adjacent to the santa monica bay in
l.A. County and across the santa barbara south coast. The lax-dag
gradient was weaker at +2.7mb compared to +4.3mb 24 hours
earlier. Have kept patchy low clouds in the forecast for coastal
areas but should remain limited to beach cities. There is a chance
that skies could remain clear across l.A. And ventura coastal
areas. The marine layer was around 1500 ft deep at 2 am near lax.

Although the marine layer is this deep, coastal valleys should
remain sunny. The inversion is very weak however, so would not be
shocked if a few patchy low clouds developed later this morning
briefly.

Synoptically, high pressure aloft (592-594dm) will be building in
from the eastern pac and stretching across much of california and
over utah az. This NW to SE elongated high will persist over the
area through the short term (today-mon). The combination of
increasing h5 heights and continued moderate onshore flow will
cause high temps to trend up today, then more gradually on
sun mon. Highs inland should be a few degrees above normal for the
most part. Not expecting heat records. As high pressure
strengthens overhead, subsidence aloft will help to lower the
marine layer depth to between 800-1200 ft. Night through morning
low clouds should become more widespread in areal coverage tonight
across most coastal areas and the santa ynez valley. Have left
stratus out of the forecast for the la vtu county valleys, but
it's not out of the question that portions of the san gabriel
could be affected during the late night and early morning hours
through Monday. The only area expecting to reach 100 degrees will
be the antelope valley while most valleys will range from the mid
80s to mid 90s. Paso robles should be near 90. High temps will
trend up another 2-5 degrees in most locations except the salinas
river valley will heat up to the upper 90s and possibly reaching
100 at paso robles.

The latest on tropical storm ivo... As of 2 am pdt the location was
390 miles wsw of the southern tip of baja ca. Ivo will continue to
weaken as it continues to move nnw parallel to baja. Ivo is
expected to be downgraded to a tropical depression sometime late
tonight into Sunday morning as it continues to enter cooler
waters. The strong high pressure over southern cal will cause ivo
to turn west away from southern cal. The only affect for southern
california will be surf related. See the "beach discussion" below
for more details. There will be some high clouds moving across
portions of the forecast area from remnants of ivo Sunday night
into Monday.

Long term (tue-fri) 24 316 am.

High pressure will will continue to dominate the weather pattern
through the extended period. With onshore gradients expected to
remain moderately strong, high temps should remain slightly above
seasonal norms through the extended period (tue-fri). Not
expecting any high cloud remnants from ivo any longer as models
keep north of the area as it gets picked up in the westerlies on
tue wed. There will continue to be night through morning low
clouds across most coastal areas and santa ynez valley through
the period, otherwise mostly clear. Maybe a slight chance for
stratus to squeeze into the san gabriel vally tue-thu.

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 24 308 am.

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.

A large southeast to south swell from tropical storm ivo will
affect the waters Sunday through Tuesday. Swell will likely
peak between 4 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 24 308 am.

Tropical storm ivo, currently about 300 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 14 seconds. The peak
of the swell heights will most likely fall between 4 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 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 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 late tonight 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.
