Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1125 PM PDT Fri Apr 24 2026

.SYNOPSIS...24/747 PM.

Cooler weather is expected over the weekend with scattered light
showers, mainly on Saturday. Dry weather is then expected for most
areas Sunday and Monday. Below normal temperatures will continue
through the middle of next week with another weak storm possible
around late Tuesday or Wednesday.

&&

.SHORT TERM (FRI-MON)...24/821 PM.

***UPDATE***

For the immediate short term, the only issue of note is a
potential for stratus clouds along the Central Coast and LA Basin.
Only moderate confidence that stratus clouds (with ceilings
between 2000 to 3000 feet) will occur. A storm system approaching
the area may cause mid to upper clouds to increase enough to
disrupt stratus formation.

The storm system is fairly weak and the impacts will be minimal.
Light scattered showers will affect portions of the area, with
the highest amounts over the mountains, especially the San
Gabriels. Rain chances will extend from Saturday afternoon through
Sunday morning, mostly Saturday evening and night. Most areas
will see rainfall totals under 0.10 inch, except for the mountains
where 0.20 to 0.30 inch totals are possible. Westerly winds will
cause downsloping across the Transverse Range, so expect to see
lower rainfall from SE Santa Barbara County to western LA County.

Saturday afternoon should see gusty onshore winds (southwest to
west) increase through the passes and canyons of the San Gabriels
into the Antelope Valley. Gusts up to 40 mph are expected, with
locally stronger gusts to 45 mph possible near Lake Palmdale. High
temperatures will be fairly cool, in the 60s for all areas, except
around 70 in the eastern Antelope Valley.

Some lingering light showers may affect a few areas, mostly the
mountains, Sunday morning with drying and clearing likely by late
morning. Highs will bump up a few degrees, mostly in the 60s still
but with a few readings around 70 in the warmer valleys.

.LONG TERM (TUE-FRI)...24/146 PM.

Another low impact weather day Tuesday except for some possible
low clouds and fog near the coast. Otherwise, temperatures within
a few degrees of normal under mostly sunny skies.

The prospects for rain later in the week appear to be decreasing,
though the deterministic GFS is still holding on to some chances
for light rain late Wednesday into Thursday morning. Most of the
ensemble solutions are showing little to no rain with temperatures
near normal. After that models are indicating weak high pressure
aloft for Friday and Saturday leading to warming temperatures.

For the Outer Waters, high confidence in current forecast. Across
the waters south of Point Conception, especially near the Channel
Islands, SCA winds will likely persist through Saturday night.
Winds could drop below advisory levels at times Saturday morning.
From Saturday afternoon through Monday, winds and seas are
expected to remain below SCA levels. Chances for SCA level winds
will increase from Tuesday onward.

For the Inner Waters north of Point Sal, moderate to high
confidence in current forecast. Localized SCA winds are possible
this evening. Otherwise, high confidence in winds and seas
remaining below SCA levels through Sunday. Chances for SCA winds
will increase each day next week.

For the Inner Waters south of Point Conception, moderate to high
confidence in current forecast. SCA level W winds are expected
later through late tonight focused across western portion of the
Santa Barbara Channel and near the Channel Islands. Increased
confidence in SCA winds across SB channel Saturday afternoon and
evening. SCA may also be needed for the waters south of Point
Mugu. On Sunday, onshore W winds will flirt with advisory levels
especially nearshore during the afternoon into early evening
hours. Slight chance for SCA level winds early next week focused
across the usually favored waters with increasing chances
Wednesday and Thursday.

A weak system will bring spotty showers across the coastal waters
Saturday and Saturday night. This activity may linger into Sunday
morning.
