AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
733 PM PDT WED JUN 3 2026
SYNOPSIS
03/1241 PM.
TEMPERATURES WILL BE SLIGHTLY ABOVE NORMAL INLAND AND NEAR NORMAL
ALONG THE COAST THROUGH FRIDAY, THEN DROPPING BELOW NORMAL OVER
THE WEEKEND AND INTO NEXT WEEK AS A LARGE LOW PRESSURE SYSTEM
DEVELOPS OVER THE WEST COAST. SKIES WILL BE MOSTLY CLEAR EXCEPT
FOR NIGHT AND MORNING LOW CLOUDS AND FOG ACROSS THE COAST AND
VALLEY AREAS.
SHORT TERM (WED-SAT)
03/110 PM.
INCREASING DRY NORTHERLY FLOW HAS MANAGED TO CLEAR THE STRATUS
FROM MOST OF THE CENTRAL COAST THIS AFTERNOON AND IT LOOKS LIKE
THIS WILL REMAIN THE CASE AT LEAST FOR THE NEXT DAY OR TWO. THIS
PATTERN IS ALSO CREATING SOME GUSTY WINDS ACROSS THE COASTAL AREAS
AND THROUGH THE GAVIOTA PASS WHERE GRADIENTS ARE EXPECTED TO
INCREASE TO 3-4MB FROM THE NORTH. LATEST HI RES MODELS KEEP WINDS
MOSTLY BELOW ADVISORY LEVELS SO FOR NOW NO WIND HAZARDS ARE IN
EFFECT BUT THIS COULD CHANGE. THE SHIFT IN WIND DIRECTION HAS
CREATED SIGNIFICANT WARMING FOR INLAND PORTIONS OF THE CENTRAL
COAST WITH TEMPS UP 5-10 DEGREES. LIKELY A SIMILAR PATTERN
THURSDAY, THEN TURNING COOLER WITH A RETURN OF THE MARINE LAYER
FRIDAY AND THROUGH THE WEEKEND.
ELSEWHERE, A SIMILAR STORY WITH REGARD TO TEMPERATURES WHERE MANY
INLAND AREAS TODAY ARE UP 5-10 DEGREES, BUT ALONG THE COAST VERY
LITTLE CHANGE. THE MARINE LAYER WAS AROUND 2200 FEET THIS MORNING
AND FORECAST SOUNDING SHOW SLIGHT LOWERING TONIGHT, SO LIKELY A
LITTLE LESS AND/OR EARLIER CLEARING ACROSS SOME OF THE VALLEYS BUT
STILL STARTING OFF THE DAY WITH LOW CLOUDS AND FOG FOR MOST
COASTAL AREAS. TEMPS EXPECTED TO BE CLOSE TO TODAY'S LEVELS IN MOST
AREAS, MEANING NEAR NORMAL AT THE COAST AND 4-8 DEGREES ABOVE
NORMAL INLAND.
GOING FORWARD, A COOLING TREND IS EXPECTED TO START FRIDAY AS A
LARGE UPPER LOW MOVES OVER THE WEST COAST. 2-4 DEGREES OF COOLING
IS EXPECTED EACH DAY THROUGH SAT. A DEEPENING MARINE LAYER IS
EXPECTED AS WELL, LEADING TO MUCH LATER CLEARING TIMES, POSSIBLY
NOT CLEARING SOME COASTAL AREAS THROUGH THE AFTERNOON.
LONG TERM (SUN-WED)
03/121 PM.
LOWER CONFIDENCE IN THE 4-7 DAY FORECAST AS SOME OF THE ENSEMBLE
MODELS ARE SUGGESTING THE UPPER LOW ARRIVING LATER THIS WEEK MAY
LINGER LONGER INTO NEXT WEEK. THIS WOULD NOT AN UNUSUAL PATTERN
FOR THIS TIME OF YEAR AND WOULD NOT BE SURPRISED TO SEE JUNE GLOOM
CONDITIONS CONTINUING LONGER. THE MODEL PERCENTAGES SEEM TO BE
FAVORING THAT SITUATION AT LEAST FOR NOW BUT POSSIBLY ONLY BY
ABOUT A 60/40 CHANCE. IF THE WARMER SITUATION PREVAILS THE
DIFFERENCE WOULD LIKELY ONLY BE ON THE ORDER OF AROUND 5 DEGREES
WITH HIGHS 3-6 DEGREES ABOVE NORMAL SO THE IMPACTS WOULD BE
RELATIVELY MINOR.
