SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
240 AM PDT THU OCT 2 2014

.SYNOPSIS...

SANTA ANA WINDS WILL STRENGTHEN THIS MORNING THROUGH EARLY
AFTERNOON HOURS AS SURFACE HIGH PRESSURE CONTINUES TO BUILD INTO THE
INTERIOR. HOT...DRY...AND GUSTY NORTHEAST WINDS AT TIMES CAN BE
EXPECTED THROUGH FRIDAY FOR PARTS OF THE AREA. OFFSHORE FLOW WILL
WEAKEN OVER THE WEEKEND...BUT THE HOT WEATHER WILL CONTINUE AS HIGH
PRESSURE BUILDS ALOFT. A COOLING TREND IS LIKELY FOR EARLY NEXT WEEK.

&&

.SHORT TERM (TODAY-SAT)...LATEST FOG PRODUCT IMAGERY INDICATED A
THIN BAND OF STRATUS FROM THE NORTHERN LA COUNTY COAST TO SANTA
BARBARA THIS MORNING. OXNARD AND SANTA BARBARA AIRPORTS WERE
REPORTING LOW CLOUDS THIS MORNING. WITH THE NE WINDS EXPECTED TO
INCREASE AND REACH THE VENTURA COAST LATER THIS MORNING. LOW CLOUDS
WILL GET MIXED OUT WHEN THE WINDS SURFACE ACROSS THE LA/VENTURA
COASTAL PLAIN...BUT PATCHY LOW CLOUDS AND FOG SHOULD REMAIN LIMITED
IN AND AROUND THE SANTA BARBARA SOUTH COAST EARLY THIS MORNING.

LATEST WIND GUST REPORTS WERE MOSTLY IN THE 30S ACROSS THE LA COUNTY
MOUNTAINS AND SANTA CLARITA VALLEY. WINDS WILL CONTINUE TO INCREASE
IN STRENGTH AND AREAL COVERAGE OVER THE NEXT SEVERAL HOURS THIS
MORNING. THE NAM-WRF SURFACE PRESSURE GRADIENT BETWEEN LAX-DAG HAS
INCREASED THE OFFSHORE TREND BY A FEW MB. AT 2 AM PDT...THE GRADIENT
WAS -3.1 MB...EXPECTED TO INCREASE TO OVER -5 MB BY 5 AM. AT THIS
POINT...LOOKS LIKE THE WINDS WILL BARELY MAKE WIND ADVISORY
THRESHOLDS THIS MORNING THROUGH THIS AFTERNOON. MOST OF THE LA BASIN
WILL NOT BE AFFECTED BY THE WINDS OVER THE NEXT FEW DAYS.
HOWEVER...THE COMBINATION OF HIGH PRESSURE BUILDING ALOFT AND A
PERSISTENT OFFSHORE FLOW EXPECTED THROUGH AT LEAST SUNDAY WILL CAUSE
TEMPERATURES TO RISE SIGNIFICANTLY TODAY ACROSS COASTAL VALLEYS AND
THE COASTAL PLAIN OF LOS ANGELES AND VENTURA COUNTIES...WITH FURTHER
WARMING FRIDAY BEFORE PEAKING ON SATURDAY. WARMEST VALLEY LOCATIONS
WILL REACH THE UPPER 90S WHILE THE COASTAL PLAIN OF VENTURA AND L.A.
WILL BE IN THE UPPER 80S TO MID 90S TODAY...THEN INCREASE TO BETWEEN
100-106 DEGREES FOR LA/VTU COUNTY VALLEYS AND THE 90S FOR THE
COASTAL AREAS.

THE CENTRAL COAST AND SANTA BARBARA WILL ALSO BE AFFECTED WITH VERY
WARM TEMPERATURES THROUGH SATURDAY AS WEAK OFFSHORE WINDS CONTINUE
OVER THE NEXT FEW MORNINGS. THERE WILL BE SOME COOLING ALONG THE
CENTRAL COAST ON SUNDAY. WARMEST LOCATIONS WILL REACH THE LOWER 90S.
INCLUDING SAN LUIS OBISPO AND SANTA MARIA.

AS FAR AS THE WINDS GO...THE STRONGEST WINDS WILL OCCUR THIS MORNING
THROUGH EARLY THIS AFTERNOON THROUGH THE USUAL WIND PRONE LOCATIONS
OF LOS ANGELES AND VENTURA COUNTIES INCLUDING THE MOUNTAINS
INCLUDING THE SANTA MONICA RANGE...SANTA CLARITA
VALLEY...NORTHWESTERN SAN FERNANDO VALLEY...THE VENTURA COUNTY
VALLEYS AS WELL AS WELL AS THE VENTURA COUNTY COASTAL PLAIN AND
BELOW THE PASSES AND CANYONS OF MALIBU TO LEO CARRILLO BEACH. WIND
ADVISORIES WERE ISSUED FOR MOST OF THESE AREAS LAST EVENING VALID
STARTING THIS MORNING. THIS FIRST RELATIVELY WEAK TO LOCALLY
MODERATE SANTA ANA EVENT IS MAINLY A SURFACE PRESSURE GRADIENT
DRIVEN WIND. STRONGEST GUSTS WILL LIKELY BE AROUND 45 MPH IN THE
MOUNTAINS...WITH LOCAL GUSTS TO 50 MPH LATER THIS MORNING...WITH
MOST VALLEYS SEEING HIGHEST GUSTS TO 40 MPH...AND COASTAL AREAS TO
35 MPH. WILL BE UPDATING WIND ADVISORY PRODUCT TO SPECIFY SPEEDS FOR
THESE LOCATIONS.

.LONG TERM (SUN-WED)...BY SUNDAY THE UPPER RIDGE WILL BEGIN TO
WEAKEN SOME AS ANOTHER WEAK UPPER LOW AND ASSOCIATED TROUGH APPROACH
THE WEST COAST OF CALIFORNIA. THERE WILL CONTINUE TO BE WEAK
OFFSHORE FLOW ACROSS THE INTERIOR AREAS OF THE FORECAST AREA THROUGH
MONDAY MORNING...SO IT WILL CONTINUE TO REMAIN VERY HOT INTO
MONDAY...WITH JUST A FEW DEGREES OF COOLING. HOWEVER THE SEABREEZE
SHOULD KICK IN A BIT EARLIER ALONG THE COAST WHERE MORE SIGNIFICANT
COOLING SHOULD OCCUR...ESPECIALLY RIGHT ALONG THE BEACHES. THERE
WILL STILL BE TRIPLE DIGIT TEMPS FOR THE LA/VTU COUNTY VALLEYS.
BETTER COOLING CAN BE EXPECTED TUE THROUGH WED AS THE UPPER RIDGE
GETS REPLACED WITH AN UPPER TROUGH TO HELP COOL THE ATMOSPHERE AND
SHIFT OFFSHORE FLOW TO ONSHORE ONCE AGAIN. HIGH TEMPS WILL BE BACK
TO MORE NORMAL FOR THIS TIME OF YEAR BY TUE/WED.

&&

.AVIATION...01/1800Z.

NEXT 24 HOURS SHOULD KEEP ANY MARINE CLOUDS AT BAY AND INSURE VFR

OF IFR CONDITIONS WITH A SURPRISE PATCH OF MARINE CLOUDS LATE
