AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
537 PM PDT SAT MAY 30 2026
SYNOPSIS
30/1226 PM.
WARMING AND DRYING THROUGH MOST OF NEXT WEEK. JUNE GLOOM CLOUDS
WILL BE PREVALENT OVER COASTAL AREAS THROUGH NEXT WEEK, BUT WILL
BE LIMITED SUNDAY AND POSSIBLY MONDAY, LEADING TO THE WARMEST TWO
DAYS. MOUNTAINS AND INTERIOR AREAS WILL LIKELY SEE THE WARMEST
CONDITIONS AROUND WEDNESDAY TO THURSDAY OF NEXT WEEK. LOCALLY
GUSTY NORTH WINDS LIKELY THROUGH MONDAY MORNING, THEN INCREASING
ONSHORE THROUGH THE WEEK.
SHORT TERM (TDY-TUE)
30/1243 PM.
THE WELL ADVERTISED WARM AND DRY PERIOD IS UNDERWAY AND 24 HOUR
TRENDS SHOW UP TO 15 DEGREES OF WARMING SO FAR, WARMEST OVER
INTERIOR MOUNTAINS AND VALLEYS. ADDITIONAL 5-10 DEGREES OF WARMING
EXPECTED FOR TOMORROW AS HIGH PRESSURE STRENGTHENS AND OFFSHORE
WINDS LIMIT MARINE INFLUENCES AT THE COASTS AND COASTAL VALLEYS.
AN UPTICK IN ONSHORE FLOW WILL ALLOW FOR TEMPERATURES TO DECREASE
SLIGHTLY ON THE COASTAL SIDE OF THE MOUNTAINS MONDAY AND TUESDAY
WHILE INTERIOR AREAS WILL CONTINUE TO WARM UP.
WIND ADVISORIES HAVE BEEN ISSUED FOR SOUTHWEST SANTA BARBARA
COUNTY AND THE I-5 CORRIDOR FROM THIS AFTERNOON THROUGH SUNDAY
MORNING, WHERE NORTHWEST TO NORTH WINDS ARE EXPECTED TO BE 20-30
MPH WITH GUSTS TO 50 MPH. WINDS 15-25 MPH WITH GUSTS TO 40 MPH
WILL BE COMMON ELSEWHERE ACROSS INTERIOR MOUNTAINS AND FOOTHILLS
TONIGHT. FAIRLY LIGHT NORTHEAST WINDS WILL BE COMMON SUNDAY
MORNING, ESPECIALLY OVER INTERIOR MOUNTAINS AND FOOTHILLS OF LA
AND VENTURA COUNTIES. NORTH WINDS WILL AGAIN BECOME PREVALENT
SUNDAY NIGHT INTO MONDAY, BUT A NOTCH WEAKER. THUS, WIND
ADVISORIES ARE NOT ANTICIPATED. ONSHORE FLOW IS EXPECTED TO
INCREASE TO THE NORTH AND SOUTH MONDAY THROUGH TUESDAY.
LOW CLOUDS HAVE FILLED IN MUCH OF THE COASTS AND VALLEYS NORTH OF
POINT CONCEPTION. SOUTH OF POINT CONCEPTION, SMALL POCKETS OF
MARINE LAYER CLOUDS HAVE FORMED, BUT SKIES REMAIN CLEAR FOR MOST
OF THE AREA. EXPECTED MARINE LAYER CLOUDS TO BURN OFF LATER TODAY,
THEN LOW CONFIDENCE IN THE EXACT RETURN AND EXTENT OF MARINE LAYER
CLOUDS TONIGHT. MORE EXPANSIVE COVERAGE ANTICIPATED INTO TUESDAY.
LONG TERM (WED-SAT)
30/1242 PM.
HIGH PRESSURE ALOFT WILL CONTINUE TO STEADILY CLIMB THROUGH
WEDNESDAY AND THURSDAY, BEFORE SLOWLY LOWERING INTO THE WEEKEND.
WHILE SOME UNCERTAINTY EXISTS IN THE EXACT TEMPERATURES,
CONFIDENCE IS HIGH THAT WEDNESDAY AND THURSDAY WILL BE THE
WARMEST DAYS OVER THE INTERIOR, AS TEMPERATURES WILL LIKELY TOP
OUT BETWEEN 90 AND 100 DEGREES. ON THE COASTAL SIDE OF THE
MOUNTAINS TEMPERATURES WILL REMAIN WARM-ISH BUT LOOK TO DROP SOME
FROM THE MONDAY PEAK AS WE HEAD TOWARDS THE END OF THE WEEK THANKS
TO THE STRENGTHENING ONSHORE FLOW. THE MAGNITUDE OF THAT COOLING
WILL DEPEND ON THE EXTENT OF THE MARINE LAYER COVERAGE. BUT THIS
TREND ALSO LOOKS LOCKED IN AS ALL THE ENSEMBLES SHOW STRENGTHENING
ONSHORE PRESSURE GRADIENTS TO THE NORTH AND EAST THROUGH THE
WEEK. HEAT ADVISORIES AND WARNINGS THROUGH THE PERIOD REMAIN
UNLIKELY. GUSTY ONSHORE WINDS SHOULD BE EXPECTED OVER THE INTERIOR
SECTIONS THROUGH THE END OF THE WEEK.
