AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
605 PM PDT FRI MAY 15 2026
SYNOPSIS
15/139 PM.
NEAR TO SLIGHTLY BELOW NORMAL TEMPERATURES ARE EXPECTED TO
CONTINUE THIS WEEKEND WITH LOW CLOUDS AND FOG LINGERING INTO THE
AFTERNOON ACROSS COAST AND SOME VALLEYS SOUTH OF PT CONCEPTION.
GUSTY WINDS ARE EXPECTED AT TIMES ALONG THE CENTRAL COAST, AND
ACROSS THE MOUNTAINS AND DESERTS THROUGH THE WEEKEND, STRONGEST ON
SATURDAY. HAZARDOUS SEAS WILL IMPACT THE COASTAL WATERS OVER THE
NEXT SEVERAL DAYS. WARMER TEMPERATURES ARE EXPECTED NEXT WEEK,
ESPECIALLY IN THE DESERT.
SHORT TERM (TDY-MON)
15/150 PM.
A 3000 FOOT MARINE LAYER WILL KEEP TEMPERATURES ON THE COOLER SIDE
THROUGH THE WEEKEND WITH HIGHS MOSTLY IN THE 60S AND 70S. THE
MARINE LAYER IS EXPECTED TO EXIT THE CENTRAL COAST AT LEAST FOR A
NIGHT OR TWO DUE TO STRONG MIXING IN THE LOWER LEVELS, BUT SHOULD
REMAIN WELL ENTRENCHED ACROSS LA/VENTURA COUNTIES. IN FACT, THERE
COULD BE SOME REVERSE CLEARING GOING ON WITH SOME COASTAL AREAS
SEEING AFTERNOON SUN EARLIER THAN THE VALLEYS.
THE MOST NOTABLE WEATHER IMPACT WILL BE THE INCREASING NORTHWEST
WINDS WHICH WILL BE STRONGEST IN THE MOUNTAINS, SOUTHWEST SANTA
BARBARA COUNTY, AND OVER THE COASTAL WATERS. WARNING LEVEL GUSTS
OF AROUND 60 MPH ARE POSSIBLE IN THE MOUNTAINS AND ANTELOPE
VALLEY, WHILE SOME OF THE OFFSHORE WATERS COULD SEE GUSTS TO 50KT
AT TIMES.
A WARMING TREND OF 4-8 DEGREES WILL BEGIN MONDAY AS PRESSURE
GRADIENTS WEAKEN AND POSSIBLY TURN SLIGHTLY OFFSHORE FOLLOWING THE
PASSAGE OF A LOW PRESSURE SYSTEM THROUGH THE GREAT BASIN.
LONG TERM (TUE-FRI)
15/209 PM.
THERE IS INCREASING UNCERTAINTY IN THE FORECAST FOR THE REST OF
NEXT WEEK PARTICULARLY WEDNESDAY AND BEYOND AS THE MODELS APPEAR
TO BE UNSURE WHETHER THE TROUGH OVER THE PAC NW WILL START TO
EXPAND SOUTH OR STAY AS IS. THE BULK OF THE LATEST GUIDANCE
NUMBERS FAVORS EITHER SLIGHT WARMING OR A LEVELING OFF OF
TEMPERATURES BUT THERE IS A GROWING NUMBER OF SOLUTIONS THAT
SUGGEST A DEEPENING OF THE TROUGH AND COOLING TEMPS FOR THE LATTER
HALF OF THE WEEK, ESPECIALLY INLAND. IN EITHER CASE, IMPACTS
WOULD BE MINIMAL WITH HIGHS WITHIN 5 DEGREES OF NORMAL IN ALL
AREAS AND JUST TYPICAL AFTERNOON SEA BREEZES.
