Area Forecast Discussion

254 AM PDT Fri Jul 11 2025

.SYNOPSIS...11/133 AM.

Night through morning low clouds and patchy fog will affect the
coasts and lower valleys into next week. Max temperatures will
cool today and Saturday and will end up several degrees below
normal. There will be continued cooling through the middle of next
week with valley highs on Tuesday only in the 80s.

.SHORT TERM (TDY-SUN)...11/238 AM.

The marine layer has risen to about 1000 ft south of Pt Conception
while it remains under 500 ft north. The onshore push is stronger
by 2 to 3 mb this morning compared to ydy both to the north and
east. As a result there is better marine layer stratus coverage.
By sunrise low clouds will cover almost all of the coasts and much
of the lower vlys. The increase in marine layer and onshore flow
will bring 1 to 2 degrees of cooling to the csts and 3 to 5
degrees across the vlys. This cooling will bring most cst/vly
locations down to a couple degrees blo normal. The onshore push
this afternoon is forecast to be near 9 mb and this is strong
enough to keep a few west facing beaches cloudy all day. The
strong onshore push will also bring gusty winds to the interior
and some places like the Antelope Vly western foothills may see
local gusts to 45 mph.

Saturday will be very similar to today. There will likely be a
little more marine layer clouds in the vlys as an eddy should spin
up. This will result it a few more degrees of cooling. Look for
70s and lower 80s for most of the csts (mid to upper 60s for the
Central Coast`s beaches) and mid 80s to mid 90s for the vlys. The
strong onshore flow will, again, keep a few beaches socked in with
clouds. Gusty west winds across the Antelope Vly may reach low end
advisory levels.

Very similar weather is likely Sunday as there will be little to
no change in the major weather parameters.

.LONG TERM (MON-THU)...11/133 AM.

Fairly dull weather on tap for the xtnd fcst. Weak ridging
extending from the SW will cover the state through Wednesday.
On Thursday weak cyclonic flow is forecast to move over the state.
Hgts will fall slowly through the period from 594 dam Monday to
590 dam on Thursday.

More importantly there will be mdt to stg onshore flow both to the
north and east. The afternoon push to the east is forecast to be
near 10 mb each day.

Look for night through morning low clouds and fog across the
coasts and into the lower vlys (the 590+ dam hgts should smoosh
the marine layer low enough to prevent deep vly penetration). The
strong onshore flow will likely mean slow to no clearing for many
beach areas.

Monday`s max temps will be near 70 at the beaches with 70s across
the rest of the coastal areas. The vlys will see max temps in the
80s and lower 90s. Tuesday`s max temps will be 2 to 4 degrees
cooler and end up 4 to 8 degrees blo normal for this time of year.
Temps will not change much from those readings on Wed and Thu.

The strong onshore flow will bring gusty likely advisory level
winds some of the mtns and the western portions of the Antelope
Vly and foothills. Additionally, the gusty winds across the mtns
and interior along with fairly warm temperatures and fairly low
humidities will bring an uptick in fire weather danger.

At this time there is no monsoon threat.

.AVIATION...11/0631Z.

At 05Z at KLAX, the marine layer was 500 ft deep. The top of the
inversion was near 2600 feet with a max temperature of 26 C.

High confidence in TAFs for KPMD, KWJF, KBUR, KVNY, KVNY, KSMX,
and KSMO.

Moderate confidence elsewhere with a 20-30 percent chance of VFR
conds prevailing, except for KSBA where there is a 30 percent
chance of IFR or lower cigs/vsbys between 12Z-20Z. Flight category
changes may be off by two hours and one flight category.

KLAX...Moderate confidence in TAF. There is a 10 percent chance of
6 kts east wind component at times between 10-17Z.

KBUR...High confidence in VFR TAF. There is a 10 percent chance of
IFR or lower cigs/vsbys between 11Z-17Z.

&&

.MARINE...11/208 AM.

Small Craft Advisory (SCA) level winds will continue across the
Outer Waters south of Point Conception through early this

Otherwise, widespread SCA conditions are unlikely through at least
early next week.

Night to morning patchy dense fog is possible at times through
this weekend.
