AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
419 AM PDT SAT JUN 14 2025
SYNOPSIS
14/218 AM.
INCREASING HIGH PRESSURE ALOFT WILL BRING WARMING TEMPERATURES TO
MOST AREAS TODAY AND SUNDAY. THE WARMEST TEMPERATURES WILL OCCUR
ACROSS THE INTERIOR AWAY FROM THE COOLING EFFECTS OF THE MARINE
LAYER. GUSTY NORTHERLY WINDS WILL DEVELOP SUNDAY EVENING THROUGH
EARLY NEXT WEEK ACROSS SOUTHERN SANTA BARBARA COUNTY AND THROUGH
THE INTERSTATE 5 CORRIDOR.
SHORT TERM (TDY-MON)
14/253 AM.
THE MARINE LAYER IS DRASTICALLY REDUCED NORTH OF PT CONCEPTION
WITH ALL OF THE WATERS CLEAR AND THE ONLY LOW CLOUDS CONFINED TO
WESTERN SBA COUNTY. SOUTH OF PT CONCEPTION A 1400 FT MARINE LAYER
AND ONSHORE FLOW HAVE BROUGHT LOW CLOUDS TO THE CSTS AND MOST OF
THE VLYS. THE OFFSHORE TRENDS SHOULD BRING FASTER AND MORE
COMPLETE CLEARING TODAY. THE FASTER CLEARING MARINE LAYER,
OFFSHORE TRENDS AND SLIGHTLY HIGHER HGTS WILL RESULT IN 2 TO 4
DEGREES OF WARMING FOR AREAS SOUTH OF PT CONCEPTION WHILE AREAS
NORTH WILL SEE LITTLE CHANGE.
BREEZY SUNDOWNER WINDS WILL RAMP UP TONIGHT AND WILL COME CLOSE TO
ADVISORY LEVELS ACROSS THE WESTERN SBA COUNTY SOUTH COAST. THESE
WINDS WILL KEEP THE SOUTH COAST CLOUD FREE AS WELL. ELSEWHERE
THERE WILL BE LESS LOW CLOUDS, ESP IN THE VLYS, AS BUILDING HIGH
PRESSURE SMOOSHES THE MARINE LAYER TO UNDER 1000 FT AND THE
OFFSHORE TRENDS CONTINUE.
SUNDAY WILL BE THE WARMEST DAY AS WELL AS THE SUNNIEST. HGTS PEAK
NEAR 591 DAM AND THE ONSHORE PUSH TO THE EAST WILL BE THE WEAKEST.
ACTUAL OFFSHORE FLOW WILL DEVELOP FROM THE NORTH. MOST AREAS WILL
WARM 3 TO 6 DEGREES. THE BIG EXCEPTION WILL BE THE SBA SOUTH COAST
WHERE BETTER N TO S OFFSHORE FLOW WILL BRING DOWNSLOPE WARMING AND
A 12 TO 15 DEGREE BUMP UP IN TEMPS. THE LESSER EXCEPTION WILL BE
THE CENTRAL COAST WHERE TEMPS WILL NOT CHANGE MUCH. HIGHS ACROSS
THE ANTELOPE VLY WILL RANGE FROM 101 TO 103 DEGREES WHILE THE VLYS
WILL COME IN WITH READINGS IN THE 90S. THESE TEMPS WILL BE CLOSE
TO ADVISORY LEVELS BUT JUST UNDER.
SUNDOWNER WINDS WILL PEAK SUNDAY NIGHT. GUSTS OF 35 TO 55 MPH
WILL BE COMMON FROM GAVIOTA TO THE SAN MARCOS PASS. ISOLATED
GUSTS NEAR 60 MPH ARE POSSIBLE NEAR GAVIOTA/REFUGIO. WIND
ADVISORIES ARE ALMOST A CERTAINTY DURING THIS TIME.
A LITTLE TROF WILL RIPPLE THROUGH THE STATE ON MONDAY. IT WILL
LOWER HGTS AND INCREASE THE ONSHORE FLOW. THERE WILL BE A LITTLE
MORE LOW CLOUDS IN THE MORNING. MAX TEMPS WILL DIP 1 TO 3 DEGREES,
BUT MOST AREAS WILL REMAIN 4 TO 8 DEGREES ABOVE NORMAL.
LONG TERM (TUE-FRI)
14/320 AM.
MORE COOLING ON TAP FOR TUESDAY, ESP FOR THE SBA SOUTH COAST
WHERE THE NORTHERLY OFFSHORE FLOW WILL SHUT OFF. MOST MAX TEMPS,
WITH THE EXCEPTION OF THE CENTRAL COAST, WILL REMAIN ABOVE NORMAL.
A LITTLE RIDGE WILL BRING WARMING TO MOST OF THE AREA WEDNESDAY
EXCEPT FOR THE LA/VTA VLYS WHERE A STRONGER SEA BREEZE WILL BRING
A FEW DEGREES OF COOLING.
TROFFING IS ON TAP FOR NEXT THU AND FRI. ONSHORE FLOW TO THE EAST
WILL ALSO RAMP UP TO BETWEEN 8 AND 9 MB. LOOK FOR A RETURN OF THE
MARINE LAYER STRATUS TO THE CSTS AND VLYS. CLEARING WILL BE SLOW
WITH MANY BEACHES LIKELY REMAINING CLOUDY ALL DAY. MAX TEMPS WILL
FALL EACH DAY AND MANY AREAS WILL SEE BELOW NORMAL MAX TEMPS. THE
ANTELOPE VLY WILL REMAIN ABOVE NORMAL HOWEVER DUE TO DOWN SLOPING
WESTERLY WINDS. THE STRONG ONSHORE FLOW WILL ALSO BRING GUSTY
WINDS TO THE MTNS AND THE WESTERN ANTELOPE VLY.
