NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
346 AM PDT SAT AUG 29 2026
SYNOPSIS
29/310 AM.
HOT AND MUGGY CONDITIONS WILL LINGER IN SOME AREAS THROUGH
SATURDAY, WITH WIDESPREAD IMPROVEMENT BY SUNDAY. MORE WARM,
TROPICAL MOISTURE COULD RETURN TUESDAY THROUGH THURSDAY. MARINE
LAYER CLOUDS WILL GRADUALLY REDEVELOP, AND INCREASE IN COVERAGE
SUNDAY INTO EARLY THIS COMING WEEK.
SHORT TERM (TDY-MON)
29/330 AM.
SOUTHWEST CALIFORNIA IS FINALLY BEGINNING TO RETURN TO MORE
NORMAL TEMPERATURES, AND HUMIDITIES WILL BE LOWERING AS WELL,
THOUGH IT MAY TAKE UNTIL SUNDAY TO REALLY NOTICE THE DIFFERENCE.
THE SOURCE OF THE TROPICAL MOISTURE IS IN THE PROCESS OF MOVING
EAST BUT THERE'S STILL SOME LEFT OVER MOISTURE OFF THE COAST THAT
WILL TAKE MOST OF THE DAY TO SCOOT EAST. THE GOOD NEWS IS THAT
ONSHORE FLOW HAS ALREADY STARTED TO INCREASE AND MOST AREAS WILL
EXPERIENCE ANYWHERE FROM 3 TO 8 DEGREES OF COOLING TODAY, THE
HIGHEST BEING ALONG THE CENTRAL COAST WHERE A SHALLOW MARINE LAYER
IS BEGINNING TO RE-ESTABLISH AND THERE WILL LIKELY BE SOME DENSE
FOG MOVING ONSHORE THIS MORNING.
THE COOLING TREND WILL CONTINUE SUNDAY AND MONDAY WITH MOST AREAS
FIRMLY BACK TO NORMAL OR EVEN LOCALLY BELOW NORMAL WITH A
DEEPENING MARINE LAYER THAT MAY EVEN REACH SOME OF THE COASTAL
VALLEYS.
INCREASING SUNDOWNER WINDS ARE EXPECTED THIS EVENING ACROSS
SOUTHWEST SANTA BARBARA COUNTY WITH WINDS GUSTING UP TO 50 MPH.
LONG TERM (TUE-FRI)
29/346 AM.
UNCERTAINTY REMAINS IN THE 4-7 DAY FORECAST AS THERE ARE STILL
SOME SOLUTIONS FAVORING A RETURN TO A MORE TROPICAL PATTERN NEXT
WEEK AND BEYOND. HOWEVER, MORE OF THE ENSEMBLE SOLUTIONS ARE
LEANING TOWARD A RELATIVELY NORMAL WEATHER PATTERN THROUGH MID
WEEK WITH A SLOW WARMING TREND WED INTO NEXT WEEKEND THAT COULD
BRING 90 DEGREE TEMPS BACK TO DOWNTOWN LA AND AROUND 100-105 IN
THE WARMER VALLEYS.
