AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
824 PM PST WED FEB 18 2026
UPDATED AND CORRECTED MARINE SECTION
SYNOPSIS
18/1235 PM.
THERE WILL BE A FEW SHOWERS THROUGH THIS AFTERNOON, OTHERWISE IT
WILL BE SUNNY AND DRY BUT COOL AND BREEZY. ANOTHER STORM WILL MOVE
INTO THE AREA THURSDAY BRINGING MORE RAIN AND MOUNTAIN SNOW. THEN
DRY WEATHER EXPECTED OVER THE WEEKEND AND MONDAY BEFORE ANOTHER
STORM IS POSSIBLE NEXT TUESDAY.
SHORT TERM (WED-SAT)
18/133 PM.
LAST NIGHT'S STORM IS LONG GONE BUT THERE ARE STILL A FEW
LINGERING LIGHT SHOWERS IN NORTHWEST FLOW, MOSTLY IN THE MOUNTAINS
AND CENTRAL COAST, BUT CAN'T RULE OUT A FEW DROPS ACROSS THE
LA/VENTURA VALLEYS. OTHERWISE, JUST COOL AND BREEZY CONDITIONS
THROUGH THIS EVENING.
THE NEXT STORM IS RAPIDLY APPROACHING FROM THE NORTHWEST. RAIN IS
EXPECTED TO RETURN TO THE CENTRAL COAST OVERNIGHT TONIGHT, THEN
INTO LA/VENTURA COUNTIES BETWEEN 6 AND 8 AM THURSDAY MORNING.
THIS WILL BE ANOTHER QUICK MOVING SYSTEM WITH AROUND 6 HOURS OF
PRECIPITATION, MOST OF WHICH WILL BE LIGHT TO MODERATE. HOWEVER,
THE LATEST HI RES MODELS ARE INDICATING AROUND A 30-50 PERCENT
CHANCE OF RAIN RATES REACHING A HALF INCH PER HOUR SO SOME POCKETS
OF AT LEAST BRIEF HEAVY RAIN ARE PRETTY LIKELY AT TIMES. THESE MAY
BE ASSOCIATED WITH CONVECTIVE CELLS WHICH COULD ALSO GENERATE
ISOLATED THUNDERSTORMS, MAINLY NORTH OF PT CONCEPTION. OVERALL
AMOUNTS ARE EXPECTED TO BE A HALF INCH OR LESS, BUT AREAS THAT GET
THOSE SMALL POCKETS OF HEAVY RAIN AND THE MOUNTAINS WILL GET
CLOSER TO 1 INCH. SNOW LEVELS WILL BE BETWEEN 4000 AND 5000 FEET,
ALTHOUGH SOME LIGHT ACCUMULATIONS ARE POSSIBLE DOWN TO AROUND 3000
FEET AS THE STORM ARRIVES. 5-10 INCHES OF SNOW POSSIBLE ABOVE
6000 FEET AND AN INCH OR SO DOWN TO GRAPEVINE LEVEL AT 4000 FEET
SO ANYONE PLANNING TRAVEL OVER INTERSTATE 5 OR ANY OF THE OTHER
MOUNTAIN ROADS SHOULD BE PREPARED FOR DELAYS OR TEMPORARY
CLOSURES. LINGERING SNOW SHOWERS ARE POSSIBLE SEVERAL HOURS AFTER
THE STORM HAS PASSED, ESPECIALLY THE NORTH FACING SLOPES BORDERING
KERN COUNTY, WHICH INCLUDES THE GRAPEVINE. FOR THIS REASON THE
WINTER STORM WARNING REMAINS IN EFFECT THROUGH 7AM FRIDAY.
WINDS WILL BE INCREASING THROUGH THE MORNING AS THE STORM PASSES
AND WINDS SHIFT TO THE WEST, PEAKING IN THE LATE MORNING THROUGH
AFTERNOON HOURS. WINDS WILL BE STRONGEST IN THE INTERIOR,
INCLUDING INTERIOR SLO AND SB COUNTIES AND THE ANTELOPE VALLEY
WHERE GUSTS TO 65 MPH ARE POSSIBLE. ELSEWHERE WINDS ARE EXPECTED
TO BE IN THE 25-40 MPH RANGE. WOULD STILL RECOMMEND PARKING CARS
AWAY FROM TREES.
THURSDAY NIGHT WILL POSSIBLY BE ONE THE COLDEST MORNINGS IN
SEVERAL WEEKS AS SKIES CLEAR OUT AND WINDS DROP OFF. EXPECT TO SEE
LOTS OF 30S ACROSS THE VALLEYS AND CENTRAL COAST AND UPPER 30S
TO MID 40S ACROSS THE COASTAL AREAS.
ASIDE FROM SOME POSSIBLE LIGHT SNOW SHOWERS EARLY FRIDAY MORNING,
THE REST OF FRIDAY IS EXPECTED TO BE DRY, BUT COOL WITH HIGHS
MOSTLY IN THE MID 50S TO LOW 60S. A SLOW WARMING TREND WILL BEGIN
SATURDAY.
LONG TERM (SUN-WED)
18/144 PM.
12Z MODELS NOW ARE TRENDING LATER AND LIGHTER WITH THE NEXT STORM,
NOT ARRIVING HERE UNTIL AT LEAST MONDAY NIGHT. IN THE MEANTIME,
THE SLOW WARMING TREND WILL CONTINUE THROUGH MONDAY, WARMING A FEW
DEGREES EACH DAY, BUT STILL WITH SOME CHILLY MORNINGS, POSSIBLY
WITH AREAS OF FROST.
WHILE THERE ARE STILL QUITE A FEW DIFFERING OPINIONS ON THE NEXT
SYSTEM, MODELS ARE TRENDING LIGHTER, AND DELAYING THE ARRIVAL TO
LATER MONDAY OR EARLY TUESDAY. THERE ARE STILL A HANDFUL SHOWING
1-2 INCHES OF RAIN BUT MOST SOLUTIONS ARE UNDER A HALF INCH. THEN
LIKELY DRY WEATHER THE REST OF THE WEEK.
