AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
451 PM PDT SAT JUN 6 2026
SYNOPSIS
06/322 AM.
TEMPERATURES WILL REMAIN NEAR TO SLIGHTLY BELOW NORMAL THROUGH
AT LEAST EARLY NEXT WEEK AS A SERIES OF LOW PRESSURE SYSTEMS MOVE
THROUGH THE REGION. LOW CLOUDS AND FOG WILL COVER MOST OF THE
COAST AND VALLEY LOCATIONS THROUGH AT LEAST MID MORNING, CLEARING
TO NEAR THE BEACHES EACH AFTERNOON. A WARMING TREND IS EXPECTED
LATER NEXT WEEK.
SHORT TERM (TDY-TUE)
06/203 PM.
LOW PRESSURE SYSTEMS MOVING THROUGH THE PAC NW WILL CONTINUE TO
KEEP TEMPERATURES ON THE COOLER SIDE ACROSS SOUTHWEST CALIFORNIA
AT LEAST ONE MORE DAY. IN FACT, THE MARINE LAYER IS EXPECTED TO
DEEPEN EVEN FURTHER TONIGHT, AROUND 3500 FEET IN LA AND 1500-2000
FEET ACROSS THE CENTRAL COAST. THIS IS EXPECTED TO DELAY THE
CLEARING FOR COAST AND VALLEYS AND LEAD TO SLIGHTLY COOLER
TEMPERATURES. HIGHS TODAY ACROSS THE INLAND AREAS ARE TRENDING
5-10 DEGREES COOLER THAN YESTERDAY AND EXPECT AT LEAST A FEW MORE
DEGREES OF COOLING SUNDAY.
WE'LL START TO TURN THE CORNER MONDAY AS HIGH PRESSURE STARTS TO
BE BUILD IN FROM THE WEST. THE MARINE LAYER WILL BEGIN TO SHRINK
WITH PROGRESSIVELY EARLIER CLEARING TIMES NEXT WEEK. TEMPERATURES
WILL BE GRADUALLY WARMING AS WELL, ESPECIALLY INLAND, BUT
GENERALLY STAYING IN THE 80S IN THE VALLEYS AND 90S IN THE FAR
INTERIOR.
ONE FEATURE TO KEEP AN EYE ON IS THE EXPECTED RETURN OF SUNDOWNERS
ACROSS SOUTHWEST SANTA BARBARA COUNTY, PEAKING MONDAY AND TUESDAY
EVENINGS WITH GUSTS BETWEEN 40 AND 50 MPH, MAINLY WEST OF GOLETA.
LONG TERM (WED-SAT)
06/230 PM.
HIGH PRESSURE IS EXPECTED TO STRENGTHEN ACROSS THE EASTERN PACIFIC
AND CALIFORNIA AT LEAST THROUGH WEDNESDAY. THIS WILL BRING AT
LEAST SOME WARMING TO MOST AREAS, BUT DEFINITELY FAVORING THE
INTERIOR AREAS LIKE THE ANTELOPE VALLEY AND INTERIOR SLO AND SANTA
BARBARA COUNTIES WHICH WILL BE MOSTLY IMMUNE TO ANY ONSHORE
INFLUENCE. IN THOSE AREAS THERE IS 60-80 PERCENT CHANCE OF 100
DEGREES OR HIGHER BY THE END OF NEXT WEEK. COASTAL VALLEYS WILL
WARMING AS WELL BUT THE LATEST ENSEMBLE PRESSURE GRADIENTS SUGGEST
AT LEAST A 5-7MB ONSHORE FLOW EACH AFTERNOON WHICH SHOULD KEEP
WARMER VALLEY HIGHS IN THE LOW TO MID 90S AND DOWNTOWN LA AND
OTHER INTERMEDIATE AREAS BETWEEN THE COAST AND VALLEYS IN THE IN
THE 70S TO LOWER 80S. NIGHT AND MORNING LOW CLOUDS AND FOG ARE
EXPECTED TO BE A DAILY OCCURRENCE ACROSS ALL COASTAL AREAS NEXT
WEEK AS WELL AS MOST COASTAL VALLEYS THROUGH AT LEAST MID WEEK AND
POSSIBLY BEYOND DEPENDING ON THE STRENGTH OF THE HIGH.
SUNDOWNERS ARE EXPECTED TO WEAKEN BY WEDNESDAY, BUT POSSIBLY
RETURNING NEXT WEEKEND.
