Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
236 AM PDT Fri Jun 12 2026

.SYNOPSIS...12/208 AM.

Night through morning low clouds and fog will cover most of the
coasts and many valley locations through the weekend and into
early next week. Highs will cool slightly through Sunday. Most
high temperatures will remain above normal, with the exception of
the coasts, which will see temperatures near to slightly below
normal.

.SHORT TERM (TDY-SUN)...12/208 AM.

Very typical June weather will dominate the short and long term
weather for Srn CA. At the upper levels the southern portion of
the state will be under an col area with hgts near 589 dam. At
the sfc there there will be mdt to stg onshore flow both to the N
and the E strongest in the afternoon.

There is no eddy tonight so the low clouds are moving into the
cstl areas at a much slower pace than last night. The marine layer
depth is only around 1000 ft and there will be less vly coverage
this morning compared to ydy morning. The strong gradients will
bring hinder clearing and some beaches will remain cloudy all day.
This marine layer pattern (early evening arrival and late morning
or early afternoon departure) will continue through Sunday and
beyond.

The strong (8-9 mb) onshore push in the afternoon will bring
enhanced seabreezes and gusty afternoon winds to the western
Antelope Vly each day. The winds will not reach advisory levels.

The increasing onshore flow and expanded marine layer coverage
will bring a slow cooling trend through the weekend. Look for 70s
and lower 80s across the csts and mid 80s to lower 90s over the
vlys. Due to the high hgts the mtns and interior will experience
above normal temps while the csts/vlys will be fairly close to
normal.

Both the RRFS and HRRR now show a much lower chc of afternoon
convection from the upper high to the south. This latest hi rez
forecast keep all of the convection safely to the S and E of LA
county.

.LONG TERM (MON-THU)...12/208 AM.

Very little to say about the long term forecast into later next
week. Its June and the weather will be June like. Weak flow will
continue at the upper levels as the jet stream will be over WA. At
the sfc there will be little day to day change in the gradient
pattern with mdt-stg onshore flow continuing both to the north and
east.

There should be only minor day to day changes in the temperatures.
The NBM mdl shows decent cooling both next Wed and Thu but with no
changes in the synoptic pattern will take this fcst with a small
grain of salt. Max temps will continue to run near normal across
the csts/vlys and above normal for the mtns and far inland areas.

No major wind issues save for the typical gusty west winds in the
Antelope Vly in the afternoon.

.AVIATION...12/0936Z.

At 0832Z at KLAX, the marine layer was 900 ft deep. The top of
the inversion was at 4800 ft with a maximum temperature of 24 C.

High confidence in VFR TAFs for KPRB, KPMD and KWJF.

Low confidence in TAFs for KBUR and KVNY with a 40 percent chc of
LIFR/IFR cig and vis 12Z-17Z.

Moderate confidence in remaining TAFs. Timing of CIG/VSBY
restrictions may be off +/- 2 hours and flight minimums by one
category.

KLAX...Moderate confidence in TAF. There is a 30 percent chc of
BKN010-012 cigs 13Z-17Z. There is a 25 percent chc of VFR conds
arriving at 22Z. No significant east wind component expected.

KBUR... Low confidence in TAF. There is a 40 percent chc of 2SM BR
OVC004 conds 12Z-17Z.

&&

.MARINE...12/232 AM.

Conditions are generally expected to remain below Small Craft
Advisory (SCA) levels through early next week.

Light winds, becoming W at 5 to 10 kts this afternoon. Local
west to northwest wind gusts could reach or exceed 21 kts each
afternoon through early next week near Pt Conception, Pt Dume,
near the Channel Islands, western Santa Barbara Channel, and
across the San Pedro Channel. There is a low chance of SCA winds
this the weekend.

&&

.BEACHES...11/813 PM.

Another long period southerly swell (less energy) originating from
the southern Hemisphere is expected to arrive on Saturday.
Evening tides of near 7.5ft are predicted from Saturday through
Tuesday. The combination of these two factors may result in minor
to locally moderate coastal flooding for south exposed coasts,
along with potential for elevated to high surf and sneaker waves.
Even as tides lower, another southerly swell arrives which could
extend concerns into Wednesday or Thursday. Stay tuned for
updates.
