Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
824 PM PDT Mon Apr 13 2026

.SYNOPSIS...13/755 PM.

Showers over the area have diminished, with just a few isolated
light showers this evening. Dry and warmer weather is expected for
the remainder of this week. Gusty northerly winds will affect much
of the area on Thursday, shifting to northeast and becoming
focused over Los Angeles and Ventura Counties on Friday.

&&

.SHORT TERM (MON-THU)...13/823 PM.

***UPDATE***

A cold upper low moved over the area today, bringing scattered
showers and thunderstorms to the area. LA County was by far the
most affected by these storms, with plentiful lightning and brief
bursts of heavy rainfall. However, these stronger storms were not
widespread, mainly affecting the San Fernando Valley and the
mountains. Higher totals ranged from 0.15 to 0.55 inch over the
San Gabriels, with 0.15 to 0.20 inch over the San Fernando and
Santa Clarita Valleys. Much lighter totals occurred further west,
with little to no rain over the northern counties.

Gusty westerly winds are affecting many areas behind the storm
system this evening, with northwest to north winds over
Southwestern Santa Barbara County. The winds will subside
overnight, but expect a repeat of gusty Sundowner winds, somewhat
stronger than tonight but likely still below Advisory level. In
addition, gusty southwest to west winds will affect the interior
passes and canyons into the Antelope Valley.

Today`s highs were below normal, with mid to upper 60s along the
coast and valleys, and around 60 over the far interior. Expect a
warming and drying trend Tuesday into Wednesday, highs rising 4 to
8 degrees for most areas on Tuesday, with an additional few
degrees of warming on Wednesday.

.LONG TERM (FRI-MON)...13/314 AM.

An inside slider is expected to work its way down the state
line on Thursday, followed by dry NW to N flow on Friday. Thursday
morning will feature onshore flow to the east and offshore flow
from the north. On Friday there will be weak offshore flow from
both the north and east in the morning.

There will not be much wind on Thursday, but Thursday night and
Friday decent north flow will develop in the mtns with advisory
level gusts likely through the I-5 corridor and the Santa Barbara
county mountains.

Max temps will not change much on Thursday, but the offshore flow
will bring 2 to 4 degrees of warming to most of the area on
Friday.

On Saturday the upper flow turn westerly. There will still be some
offshore flow at the sfc, but with no upper support it will only
generate sub advisory canyon winds. Max temps will respond to the
continued offshore flow and 3 to 5 degrees of additional warm
seems likely. This will bring max temps up into the upper 70s to
mid 80s for most of csts/vlys which is 4 to 8 degrees above
normal.

Mdls are struggling a bit with the pattern for Sunday. All mdls
show a large upper low spinning somewhere to the NW but there is
massive disagreement on the location. For now the forecast is
similar to Saturday with just a little cooling across the csts as
the offshore flow weakens.
