AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
838 AM PST FRI FEB 13 2026
UPDATED MARINE SECTION
SYNOPSIS
13/118 AM.
DRY CONDITIONS WITH A WARMING TREND ARE EXPECTED TO CONTINUE
THROUGH SATURDAY. A STRONG STORM SYSTEM WILL AFFECT THE REGION
STARTING ON SUNDAY AND MONDAY, BRINGING THE POTENTIAL FOR HEAVY
PRECIPITATION WITH FLOODING AND MOUNTAIN SNOW, THUNDERSTORMS,
STRONG WINDS, AS WELL AS MARINE AND BEACH HAZARDS. THESE
CONDITIONS COULD LAST THROUGH MUCH OF NEXT WEEK.
SHORT TERM (TDY-SUN)
13/213 AM.
TODAY AND SATURDAY WILL BE VERY PLEASANT DAYS ACROSS THE AREA.
TODAY WILL BE THE WARMEST DAY FOR QUITE SOME TIME AS LIGHT
OFFSHORE FLOW, AMPLE SUNSHINE, AND HIGH PRESSURE ALOFT COMBINE TO
PUSH TEMPERATURES TO THE MID 70S ACROSS THE LA/VENTURA VALLEYS
AND 60S TO LOW 70S ELSEWHERE. SATURDAY WILL START OUT SUNNY BUT
MID AND HIGH CLOUDS WILL BE INCREASING THROUGH THE DAY AS THE
NEXT STORM APPROACHES. TEMPS WILL BE A FEW DEGREES COOLER AND
HIGHS WILL BE WITHIN A COUPLE DEGREES OF NORMAL IN MOST AREAS.
SUNDAY WILL BE A TRANSITION TODAY AS A POTENT STORM SYSTEM
APPROACHES FROM THE NORTHWEST. WHILE THE CENTER OF THE STORM
REMAINS QUITE A WAYS OUT, SOME LIGHT SHOWERS ARE LIKELY SUNDAY
AFTERNOON IN NORTHWEST SLO COUNTY AND POSSIBLY AS FAR AS SOUTHERN
SANTA BARBARA COUNTY AND VENTURA COUNTY BY LATE AFTERNOON AND
EVENING. HIGHS WILL FALL INTO THE 60S AREA-WIDE.
LONG TERM (MON-THU)
13/347 AM.
THE LATEST UPPER LEVEL ANALYSIS SHOWS TWO UPPER LOWS COMING
THROUGH THE AREA THROUGH WEDNESDAY, EACH WITH MULTIPLE WAVES OF
PRECIPITATION. WITH A 160KT JET ORIENTED SOUTHWEST TO NORTHEAST
ACROSS LA COUNTY, PRECIPITABLE WATERS NOW CLOSE TO 1.25", AND A
CLASSIC COLD FRONT WITH DIFFLUENCE ALOFT SLAMMING INTO THE STATE,
THIS FIRST SYSTEM HAS THE HIGHEST POTENTIAL FOR GENERATING THE
HIGHEST AMOUNTS OR PRECIPITATION OVERALL. THE LATEST ENSEMBLE
SOLUTIONS ARE CONVERGING ON AT LEAST 1-3 INCHES OF RAIN FOR COAST
AND VALLEYS WITH THE FIRST SYSTEM MONDAY AND 2-5" IN THE
MOUNTAINS. WE'RE STILL OUTSIDE THE TIME FRAME FOR THE HIGHER RES
MODELS BUT BASED ON THE NAM SHOWING 50-60 KT AT 850MB OUT OF THE
SOUTHEAST CREATING A HUGE OROGRAPHIC COMPONENT IT LOOKS LIKELY
THAT HOURLY RAIN RATES WILL REACH AT LEAST 0.75"/HOUR IN THE
TRANSVERSE RANGE BETWEEN SANTA BARBARA AND LA COUNTY AND POSSIBLY
AS HIGH AS ONE INCH PER HOUR. BECAUSE OF THIS, MONDAY HAS THE
HIGHEST CHANCE FOR DEBRIS FLOWS IN THE BURN AREAS AND OVERALL
HYDROLOGIC HAZARDS. ALSO CAN'T RULE OUT AN ISOLATED THUNDERSTORM
OR TWO GIVEN THE UPPER LEVEL PATTERN. SNOW LEVELS ARE EXPECTED TO
REMAIN ABOVE 6500 FEET MONDAY BUT SIGNIFICANT ACCUMULATIONS ARE
LIKELY ABOVE THAT.
THERE SHOULD BE A SIGNIFICANT DECREASE IN RAIN AMOUNTS AND
INTENSITIES MONDAY NIGHT INTO TUESDAY AS LOW LEVEL FLOW SHIFTS TO
THE WEST FOLLOWING THE PASSAGE OF THE FIRST COLD FRONT, BUT IT'S
ALWAYS DIFFICULT TO TIME THESE FEATURES 4 OR MORE DAYS OUT. THERE
WILL BE ENOUGH MOISTURE FOR AT LEAST SCATTERED SHOWERS THROUGH THE
DAY TUESDAY BUT RAIN RATES SHOULD BE QUITE A BIT LESS THAN
MONDAY. TEMPERATURES WILL BE COOLING ALOFT LEADING TO SNOW LEVELS
LOWERING TO AROUND 5000 FEET WITH SOME LIGHT ACCUMULATIONS
POSSIBLE.
THE SECOND UPPER LEVEL SYSTEM IS EXPECTED TO ARRIVE TUESDAY NIGHT
INTO WEDNESDAY AND THIS WILL BRING WITH IT MUCH COLDER AIR ALOFT.
WEDNESDAY HAS THE LOOK OF A VERY WACKY WEATHER DAY ACROSS SOUTHERN
CALIFORNIA AS SNOW LEVELS ARE EXPECTED TO DROP TO AT LEAST 3000
FEET, AND POSSIBLY AS LOW AS 2500 FEET AT TIMES CREATING
SIGNIFICANT DRIVING HAZARDS ON MOUNTAIN ROADS, INCLUDING
INTERSTATE 5, WHICH MAY EXPERIENCE DELAYS OR CLOSURES AT TIMES.
PW'S DROP BY 50%, BUT THIS SHOULD BE A VERY EFFICIENT RAIN AND
SNOW PRODUCER WITH PERIODS OF HEAVY PRECIPITATION AT TIMES AND
POSSIBLY EVEN SOME GRAUPEL ACROSS THE FOOTHILLS AND HIGHER
VALLEYS. RAIN AMOUNTS WILL BE HIGHLY VARIABLE FROM AS LITTLE AS A
HALF INCH IN SOME AREAS TO AS MUCH AS 1-3" IN OTHERS.
A COLD DAY ON THURSDAY BUT AT THIS TIME THE FORECAST IS FOR DRY
WEATHER.
