NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
335 AM PDT FRI APR 24 2026
SYNOPSIS
23/1143 PM.
TEMPERATURES WILL BE NEAR NORMAL TODAY, WITH A COOLING TREND OVER
THE WEEKEND AS A WEAK STORM CROSSES THE AREA. THE STORM WILL
BRING SCATTERED LIGHT SHOWERS TO THE REGION ON SATURDAY. DRY
WEATHER IS THEN EXPECTED MOST AREAS SUNDAY AND MONDAY. BELOW
NORMAL TEMPERATURES WILL CONTINUE THROUGH THE MIDDLE OF NEXT WEEK
WITH ANOTHER WEAK STORM POSSIBLE AROUND LATE TUESDAY OR WEDNESDAY.
SHORT TERM (TDY-SUN)
24/1225 AM.
FLAT WESTERLY FLOW COVERS SRN CA. SOME CIRRUS WILL DRIFT INTO AND
OVER THE AREA WITHIN THE FLOW, MAKING IT A PARTLY CLOUDY DAY.
THERE IS A CHC THAT SOME LOW CLOUDS WILL BRIEFLY FORM OVER THE
LGB-LAX AREA AROUND DAWN. INCREASING ONSHORE FLOW TO BOTH THE
EAST AND NORTH WILL BRING AN EARLIER AND STRONGER SEA BREEZE TO
THE CSTS/VLYS, WHICH WILL RESULT IN 1 TO 3 DEGREES OF COOLING. MAX
TEMPS WILL NOT CHANGE MUCH ACROSS THE INTERIOR.
A SMALL TROF WILL MOVE IN AND THROUGH SLO COUNTY AND THEN OVER
KERN COUNTY ON SATURDAY. IT WILL BRING ENOUGH CLOUDS TO MAKE IT A
MOSTLY CLOUDY DAY. IT DOES NOT HAVE ENOUGH MOISTURE AND/OR
DYNAMICS TO MAKE IT MUCH OF A THREAT. STILL, MOST AREAS WILL
LIKELY SEE SOME PERIODS OF LIGHT RAIN THROUGH THE DAY. RAINFALL
AMOUNTS FOR THE DAY AND EVENING WILL MOSTLY BE A TENTH OF AN INCH
OR LESS WITH UP TO A QUARTER INCH IN SOME MTN LOCATIONS. GUSTY
SOUTHWEST TO WEST WINDS WILL DEVELOP LATER SATURDAY, STRONGEST IN
THE ANTELOPE VALLEY WITH GUSTS TO AROUND 45 MPH. MAX TEMPS WILL
PLUMMET WITH ALL OF THE CLOUDS AND LIGHT RAIN. LOOK FOR 4 TO 8
DEGREES OF COOLING WITH MAX TEMPS ONLY IN THE 60S FOR THE
CSTS/VLYS.
THERE IS A 20 PERCENT CHC OF SOME LINGERING MORNING SHOWERS
SUNDAY MORNING PROVIDED THE SYSTEM MOVES A LITTLE SLOWER THAN THE
PREPONDERANCE OF MDL GUIDANCE INDICATES. IN THE AFTERNOON IT WILL
BE DRY WITH CLEARING SKIES SAVE FOR SOME CLOUDS AND A SLIGHT CHC
OF SHOWERS OVER THE FAR EASTERN SAN GABRIELS. IT WILL REMAIN COOL
WITH HIGHS IN THE 60S.
LONG TERM (MON-THU)
24/334 AM.
THE BOTTOM OF A WEAK POS TILT TROF WILL COVER MOST OF THE STATE ON
MONDAY AND TUESDAY. THE WEATHER WILL BE PRETTY BENIGN. MAX TEMPS
WILL RISE 1 OR 2 DEGREES EACH DAY. EVEN WITH THE WARMING MAX TEMPS
WILL END UP 3 TO 6 DEGREES BELOW NORMAL.
MDLS REMAIN CONFUSED FOR THE POTENTIAL SYSTEM LATE TUESDAY OR
WEDNESDAY. THIS LOOKS TO BE A WEAK SYSTEM WITH REALLY ONLY A 20
PERCENT CHC OF RAIN. REALLY THE ONLY WET MDL IS THE GFS WHICH
IS THE ONLY MDL THAT GENERATES A CLOSED LOW. IF IT DOES RAIN,
RAINFALL AMOUNTS, IF ANY, UNDER A TENTH OF AN INCH. MAX TEMPS WILL
END UP MOSTLY MID 60S TO THE MID 70S.
RIDGING LOOKS LIKELY FOR THU AND FRI WITH 2 TO 4 DEGREES OF
WARMING SLATED FOR EACH DAY.
