AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1008 PM PST THU MAR 5 2026
SYNOPSIS
05/444 PM.
NORTHERLY WINDS WILL SWITCH TO NORTHEAST BY FRIDAY MORNING,
KICKING OFF A MODERATE SANTA ANA WIND EVENT THAT WILL CONTINUE
THROUGH SUNDAY. TEMPERATURES WILL WARM EACH DAY THROUGH THE
WEEKEND, WITH WIDESPREAD HIGHS IN THE 80S BY SUNDAY. NO RAIN IS
EXPECTED FOR THE UPCOMING WEEK.
SHORT TERM (TDY-SAT)
05/906 PM.
***UPDATE***
A STRONG LOW PRESSURE SYSTEM PUSHING INTO THE GREAT BASIN CONTINUES
TO DRIVE POCKETS OF GUSTY WINDS OVER PORTIONS OF SANTA BARBARA,
VENTURA AND LA COUNTIES TODAY. NORTHERLY WINDS PEAKED THIS
MORNING, WITH FAVORED HIGHER ELEVATIONS REACHING GUSTS AROUND 70
MPH. THIS EVENING, WINDS HAVE COME DOWN A BIT BUT REMAIN STRONG
OVER THE EASTERN SANTA YNEZ RANGE, THE EASTERN SANTA MONICA
MOUNTAINS AND NEAR THE I-5 CORRIDOR. OVERNIGHT, WINDS WILL SHIFT
TO THE EAST, WITH THE CURRENT WIND PRODUCTS LOOKING ON TRACK. WITH
THE OFFSHORE LAX-DAG GRADIENT EXPECTED TO PEAK AROUND 5 TO 6 MB
TOMORROW MORNING AND THE LAX-BFL OFFSHORE GRADIENT AROUND 3 MB,
THIS SHOULD SUPPORT WIDESPREAD GUSTY WINDS FOR SANTA ANA WIND
PRONE AREAS. LOWER CONFIDENCE IN WINDS FOR SUNDAY, BUT CONSENSUS
IS THEY SHOULD BE WEAKER, SO CURRENT THINKING IS WIND ADVISORIES
WILL BE NEEDED FOR EARLY SUNDAY. TEMPERATURES FOR THE COASTS AND
VALLEYS MAY BE 2-5 DEGREES WARMER THAN FORECAST FOR THE WEEKEND.
***FROM PREVIOUS DISCUSSION***
A COLD AND DRY LOW PRESSURE SYSTEM WILL CONTINUE TO IMPACT THE
REGION, RESULTING IN AREAS OF GUSTY WINDS. LATE TONIGHT, THE
CURRENT NORTHERLY WINDS WILL SHIFT TO OUT OF THE NORTHEAST. THIS
WILL KICK OFF A MODERATE (TO LOCALLY STRONG) SANTA ANA WIND EVENT
THAT WILL LAST THROUGH SUNDAY. ON FRIDAY THERE WILL BE
SIGNIFICANT COLD AIR ADVECTION AND ASSOCIATED SUBSIDENCE, FOLLOWED
BY UPPER LEVEL SUPPORT ON SATURDAY, THUS BOTH DAYS WILL BE
SIMILAR WINDY. HIGH WIND WARNINGS AND WIND ADVISORIES ARE IN
EFFECT FROM LATE TONIGHT INTO SATURDAY AFTERNOON, AND MAY NEED TO
EXTENDED INTO SUNDAY. FOR LA AND VENTURA COUNTIES, GUSTS OF 30 TO
45 MPH ARE EXPECTED ACROSS FAVORED COASTAL AND VALLEY AREAS AND
GUSTS OF 45 TO 65 MPH ARE EXPECTED ACROSS THE MOUNTAINS. THE WINDS
WILL LIKELY CAUSE HAZARDOUS DRIVING CONDITIONS DUE TO CROSSWINDS
AND DEBRIS ON THE ROAD, AND DOWNED TREES AND POWER LINES RESULTING
IN POWER OUTAGES.
THE OFFSHORE FLOW WILL YIELD SIGNIFICANT WARMING TREND FRIDAY
THROUGH THE WEEKEND, WITH MANY COAST AND VALLEYS AREAS LIKELY IN
THE 80S ON SUNDAY. THE WARMEST TEMPERATURES ARE EXPECTED FOR
VENTURA AND LOS ANGELES COUNTIES, WHERE HIGHS 15+ DEGREES ABOVE
NORMAL WILL BE WIDESPREAD. MINOR TO MODERATE HEAT IMPACTS WILL BE
POSSIBLE, MAINLY FOR OUTDOOR WORKERS AND THOSE WITHOUT AIR
CONDITION. EXPECT CLEAR SKIES THROUGH THE WEEKEND TO GO WITH THE
WARM TEMPERATURES, AND VERY DRY HUMIDITY. DESPITE FAVORABLE WIND
AND HUMIDITY CONDITIONS, THERE IS LITTLE FIRE WEATHER CONCERN DUE
TO RECENT RAINS.
LONG TERM (SUN-WED)
05/226 PM.
EARLY NEXT WEEK TEMPERATURES WILL TREND COOLER AS THE OFFSHORE
WINDS DROP OFF. TUESDAY WILL LIKELY BE THE COLDEST DAY NEXT WEEK,
WHEN MOST HIGHS WILL BE IN THE UPPER 60S TO LOW 70S. BY WEDNESAY,
ANOTHER NORTHERLY WIND EVENT AND BUILDING HIGH PRESSURE ARE TO
RESULT IN A SMALL INCREASE IN TEMPERATURES. THURSDAY INTO LATE
NEXT WEEK, ANOTHER WARM SPELL IS FAVORED WITH HIGHS IN THE 80S
POSSIBLE AGAIN. DRY WEATHER WILL CONTINUE, AS THERE REMAINS NO
SIGNIFICANT CHANCES FOR RAIN.
