508 AM PDT THU MAY 14 2026
SYNOPSIS
14/205 AM.
SLIGHT WARMING IS EXPECTED FOR TODAY AND FRIDAY, LESS MARINE
LAYER CLOUDS. GUSTY WINDS ARE EXPECTED AT TIMES ACROSS THE
MOUNTAINS AND DESERTS. HAZARDOUS SEAS ARE EXPECTED FOR THE COASTAL
WATERS OVER THE WEEKEND. ABOVE NORMAL TEMPERATURES ARE POSSIBLE
EARLY NEXT WEEK.
SHORT TERM (TDY-SAT)
14/311 AM.
WEAK RIDGING WILL CONTINUE OVER THE AREA THROUGH FRIDAY, THEN
SATURDAY A DRY INSIDE SLIDER TROUGH WILL BEGIN TO IMPACT THE
REGION. 500 MB HEIGHTS WILL BE FAIRLY CONSISTENT THROUGH FRIDAY,
THEN FALL RAPIDLY SATURDAY WITH THE APPROACHING TROUGH. MODERATE-
TO- STRONG ONSHORE FLOW WILL CONTINUE EACH DAY, WITH AN INCREASE
IN NORTHWESTERLY FLOW STARTING FRIDAY. NORTHWEST TO WESTERLY WINDS
WITH GUSTS BETWEEN 20 TO 35 MPH WILL OCCUR LATE THIS AFTERNOON
AND TONIGHT ALONG THE CENTRAL COAST, SOUTHWESTERN SANTA BARBARA
COUNTY, THE ANTELOPE VALLEY, AND THE INTERIOR MOUNTAINS
(INCLUDING THE INTERSTATE 5 CORRIDOR). WINDS ACROSS THE SAME AREAS
WILL BE STRONGER FRIDAY AFTERNOON INTO SATURDAY MORNING (AND
AGAIN SATURDAY AFTERNOON INTO SUNDAY MORNING), WITH GUSTS OF 40 TO
55 MPH POSSIBLE FOR SOUTHWESTERN SANTA BARBARA COUNTY (MAINLY
THE WESTERN SANTA YNEZ RANGE), AND INTERIOR MOUNTAINS AND
DESERTS. SOME LOCAL WIND ADVISORIES MAY BE ISSUED FOR THESE TIME
PERIODS.
500 MB HEIGHTS AND ONSHORE FLOW SUPPORT THE POSSIBILITY OF LOW
CLOUDS EACH MORNING ACROSS ALL THE COASTS AND VALLEYS. HOWEVER
COLD NORTHWEST FLOW ALOFT HAS WEAKENED THE MARINE LAYER INVERSION,
THUS CLOUD COVERAGE MAY BE PATCHY, ESPECIALLY FOR AREAS NORTH OF
POINT CONCEPTION. THE GREATEST CHANCES FOR LOW CLOUDS WILL BE
THIS MORNING AND FRIDAY MORNING ACROSS LA/VENTURA COUNTIES, WHEN
NORTHWEST FLOW ALOFT WILL BE WEAKER. DAYTIME HIGHS WILL BE
MILD, WITH COASTS AND VALLEYS IN THE UPPER 60S TO UPPER 70S. EAST
OF THE MOUNTAINS, INTERIOR VALLEYS AND DESERTS WILL SEE HIGHS IN
THE 80S, WITH THE WARMEST DAY EXPECTED TO BE FRIDAY.
LONG TERM (SUN-WED)
14/344 AM.
THE INSIDE SLIDER TROUGH WILL IMPACT THE REGION THROUGH THE
WEEKEND. STRONG NORTHWEST TO WESTERLY WINDS WILL CONTINUE SATURDAY
INTO SUNDAY ACROSS MUCH OF SAN LUIS OBISPO AND SANTA BARBARA
COUNTIES, ALL BEACHES, AND THE INTERIOR MOUNTAINS AND DESERTS.
EARLY NEXT WEEK, AS THE TROUGH MOVES OUT THE AREA TO THE EAST, 500
MB HEIGHTS WILL GRADUALLY TREND UPWARDS. ADDITIONALLY THERE IS
AROUND A 30 PERCENT CHANCE OF PERIODS OF WEAK OFFSHORE FLOW,
PARTICULARLY MONDAY AND TUESDAY MORNINGS. NORTHEAST WIND GUSTS OF
AROUND 20 TO 30 MPH WILL BE POSSIBLE ACROSS THE WIND PRONE
MOUNTAINS. IF OFFSHORE FLOW DOES OCCUR, COASTAL TEMPERATURES HAVE
THE POTENTIAL TO WARM INTO THE UPPER 70S AND LOW 80S, OTHERWISE
HIGHS IN THE 60S WILL BE FAVORED. OVERALL A WARMING TREND IS
EXPECTED MONDAY THROUGH WEDNESDAY, WITH THE HIGHEST CONFIDENCE FOR
INLAND AREAS. AWAY FROM THE BEACHES, HIGHS WILL INCREASE FROM MID
70S TO MID 80S ON MONDAY, TO LOW 80S TO AROUND 90 DEGREES ON
WEDNESAY (5 TO 10 DEGREES ABOVE NORMAL). MARINE LAYER LOW CLOUDS
AND FOG WILL BE POSSIBLE EACH DAY ACROSS THE COAST AND VALLEYS.
