National Weather Service Los Angeles/Oxnard CA
500 AM PDT Tue Jun 24 2025

.SYNOPSIS...24/300 AM.

Another day of well below normal temperatures, then turning warmer
Wednesday through Friday as weak high pressure returns. Night
through morning low clouds and fog are expected for many coastal
areas this week, but decreasing across the valleys. Otherwise
clear skies with mostly light winds are expected.

&&

.SHORT TERM (TDY-THU)...24/253 AM.

Very low impact weather across southwest California the next few
days and really through at least early next week as well. A trough
of low pressure continues to linger over Central California and
Nevada which will keep temperatures 4-8 degrees below normal
area-wide today. Marine layer stratus has filled in most
coast/valley areas early this morning but will pull back to the
beaches by afternoon.

The trough will exit to the east Wednesday which will begin a
warming trend. Most of the warming will occur on Wednesday when
inland areas jump almost 10 degrees from Tuesday`s levels. After
that just very minor upward adjustments to highs Thu. Even with
this warming trend highs will still only be within a couple
degrees of normal in most areas, except around 5 degrees above
normal across the Antelope Valley and far interior SLO County.
Morning low clouds and fog will be less extensive across the
valleys but solid near the coast with typical slow clearing.

.LONG TERM (FRI-MON)...24/258 AM.

High temperatures will remain very similar later this week and
possibly even into early next week as a very weak trough will
persist along the West Coast. Not seeing any large scale gusty
winds coming through the period and temperatures will remain near
normal, except a little above normal inland. Some model solutions
are showing a deeper trough developing early next week that could
fast track a cooling trend.
