Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
117 PM PST Wed Dec 10 2025

.SYNOPSIS...10/1214 PM.

A warm weather pattern will continue through the next week over
much of the area, but some cooling will develop for late week a
high pressure aloft weakens. A shallow marine layer depth will
develop for the end of the week and could bring dense fog to the
coastal areas. A warming trend will develop again for early next
week.

&&

.SHORT TERM (TDY-SAT)...10/1247 PM.

Another warm day is occurring across southwestern California this
afternoon. Daytime high temperatures are well above normal, so
far, hovering close to record daily high values. Clear skies
remain prevalent across the area as a strong blocking ridge of
high pressure aloft continue to drive a warmer and drier weather
pattern.

A cooling trend should develop over the coming days as a weak
trough will replace the ridge. The ridge axis should move over the
region tonight or early Thursday morning and high pressure aloft
should start to break down. Temperatures will likely remain above
normal through the period as 500 mb heights do not drop enough. A
return of onshore flow late this week should bring a return of low
clouds and fog. A shallow marine layer depth looks likely to
develop across the coast and dense fog could become an issue as we
move forward into Friday and Saturday.

.LONG TERM (SUN-WED)...10/109 PM.

Ridging aloft will restablish early next week and likely
strengthen through the week. A warming and drying trend will
restablish early next week with temperatures likely going well
above normal again by the middle of next week. Offshore flow is
likely to redevelop again, although not as strongly as it was this
week.

&&

.AVIATION...10/1653Z.

At 1629Z at KLAX, there was no marine layer. There was a surfaced
based inversion with a top of 1600 ft and a temperature of 24 C.

High confidence in VFR TAFs.

KLAX...High confidence in TAF. Any east wind component will
be less than 7 knots.

KBUR...High confidence in VFR TAF.

&&

.MARINE...10/115 PM.

Localized Small Craft Advisory wind gusts are likely across the
far NW portion of PZZ670 through this evening. Otherwise, high
confidence in fairly calm conditions and lowering seas through
this weekend. SCA level winds are likely to return across the
Outer Waters south of Point Conception next week.

Some dense fog will form in the coastal waters by Thursday or
Friday, but low confidence on when and where.
