Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
437 AM PDT Fri Jul 4 2025
UPDATED AVIATION SECTION
.SYNOPSIS...04/312 AM.
Temperatures will be near normal for July through at least this
weekend, with overnight to morning low clouds and fog continuing
for the coasts and valleys. Tuesday through much of next week an
extended period of well above normal temperatures is expected.
&&
.SHORT TERM (TDY-SUN)...04/310 AM.
Temperatures today will be a few degrees below normal, with
highs in the 70s for the coasts, 80s for most valleys, and mid
90s across the deserts. Weak troughing will maintain similar
temperatures this weekend, except for a couple degrees of warming
for the LA Basin. Overnight to morning marine layer clouds and
fog will continue for the coasts and valleys each day, even
lingering into the day at some beach locations. Smoke from the
Madre Fire in southeastern San Luis Obispo County may impact the
region, but will likely be fairly elevated for most areas. In
terms of winds, typical onshore west to southwesterly winds will
occur each afternoon and evening across interior areas including
the Antelope Valley, and northwest Sundowner winds will occur
each evening across southwestern Santa Barbara County.
.LONG TERM (MON-THU)...04/257 AM.
Weak troughing will continue for the region Monday and keep
conditions similar to the weekend, with temperatures generally
near or several degrees below normal. Tuesday through at least
Thursday a high pressure system will build centered over Arizona.
This will send 500 mb heights soaring over Southern California
with heights around 597 dam likely over Los Angeles County.
Temperatures will be notably warmer on Tuesday, with heat peaking
on Wednesday or Thursday for most areas. Temperatures will easily
surpass 100 degrees across the deserts and interior valleys and
mountains. Highs in the mid 80s to mid 90s will be common across
the coastal plains including DTLA, and even some coastal areas may
see temperatures well into the 80s, especially on Thursday.
Heat Advisories are likely to be issued for most valleys for mid
next week, though well above normal conditions may linger through
the next weekend. Additionally, if the forecast continues to trend
warmer, there is a chance that Extreme Heat Watches/Warnings will
be needed for many valley, desert, and mountain areas. Residents,
particular outdoor workers and those without air conditioning,
are advised to prepare for an extended period of above normal
temperatures.
Southeasterly flow aloft may bring some monsoonal mositure to the
region, with PWATs of an inch or more possible, especially for LA
County. This mositure combined with high surface heating will
offer a small chance for monsoonal thunderstorms each afternoon
Tuesday through Thursday. Thunderstorm chances will be focused
over the Antelope Valley and the San Gabriel Mountains, with
slimmer chances for the Ventura County Mountains and far eastern
Santa Barbara and San Luis Obispo Counties. Hazards with any
storm may include dry lightning fire starts, gusty winds, and
brief heavy downpour.
&&

for no low clouds returning tonight. Moderate confidence in any
east wind component remaining under 6 kts.
KBUR...High confidence in TAF through 06Z, then low confidence
thereafter. Clearing time may be off by +/- 90 minutes. There is
a 20% chance of LIFR to IFR conds developing after 06Z.

the weekend.
Inside the southern California bight, there is a moderate chance
of SCA level winds each afternoon and evening Friday through the
