SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
440 AM PDT THU MAR 12 2015

UPDATED AVIATION SECTION

...RECORD HIGH TEMPERATURES EXPECTED THIS WEEKEND FOR SOME COASTAL
AND COASTAL VALLEY LOCATIONS...

.SYNOPSIS...
HOT AND DRY WEATHER IS EXPECTED THROUGH MONDAY...WITH SATURDAY AND
SUNDAY BEING THE HOTTEST. HIGH PRESSURE AND OFFSHORE BREEZES WILL
KEEP TEMPERATURES WELL ABOVE SEASONAL NORMALS. A COOLING TREND AND
RETURN OF THE MARINE LAYER WILL ARRIVE EARLY NEXT WEEK.

&&

.SHORT TERM (TODAY-SAT)...LATEST FOG PRODUCT IMAGERY INDICATED
MOSTLY CLEAR SKIES EXCEPT FOR STRATUS ACROSS THE ENTIRE SANTA YNEZ
VALLEY AND THE INTERIOR AREAS OF SLO/SANTA BARBARA COUNTIES
INCLUDING THE NORTHERN SLOPES OF THE VENTURA COUNTY MOUNTAINS. SOME
STRATUS WAS ALSO TRYING TO DEVELOP ALONG THE SANTA BARBARA CENTRAL
COAST. THE CLOUDS BANKING UP AGAINST THE NRN SLOPES SHOULD LINGER
THROUGH NOON TODAY.

THE WEAK FRONTAL SYSTEM THAT MOVED THROUGH THE AREA DID LITTLE TO
COOL THE ATMOSPHERE AS THE LATEST AMDAR SOUNDING AROUND KLAX
INDICATED A VERY SHALLOW AND STRONG INVERSION AROUND 200 FT DEEP.
NOT ANTICIPATING ANY STRATUS TO DEVELOP FOR AREAS S OF POINT
CONCEPTION...BUT IF RANDOM LOW CLOUDS DO FORM ALONG THE COAST IT
WILL BE DENSE. GUSTY NORTHERLY WINDS HAVE ALREADY DEVELOPED ACROSS
PORTIONS OF THE LA/VTU/SBA COUNTY MOUNTAINS. LAX-BFL GRADIENT WAS
JUST UNDER -4 MB. WINDS WILL SPREAD INTO THE SANTA CLARITA AND SAN
FERNANDO VALLEYS LATER THIS MORNING...THEN OVER THE SEPULVEDA PASS
INTO THE WEST LA. THE STRONGEST WINDS WILL OCCUR ACROSS THE
MOUNTAINS AND SANTA CLARITA VALLEY...BUT SHOULD REMAIN JUST BELOW
WIND ADVISORY LEVELS. THERE WILL BE A FEW OUTLIER MOUNTAINS STATIONS
THAT COULD SEE GUSTS OVER 50...SUCH AS WHITAKER PEAK IN THE MORNING.
WINDS WILL QUICKLY SHIFT TO THE NORTHEAST LATE THIS MORNING AND
WINDS WILL BECOME MORE WIDESPREAD INTO THE WIND PRONE VENTURA COUNTY
VALLEYS AND COAST. AGAIN...WINDS SHOULD REMAIN UNDER ADVISORY
LEVELS. IF WINDS DO STRENGTHEN LATER THIS MORNING...THEN THE DAY
SHIFT COULD ISSUE A WIND ADVISORY FOR THE USUAL SANTA ANA WIND PRONE
AREAS FOR LA/VTU COUNTIES.

SYNOPTICALLY... A POSITIVE TILTED AMPLIFIED UPPER RIDGE WILL QUICKLY
BUILD ACROSS THE WEST COAST INTO VANCOUVER CANADA THIS
AFTERNOON...ONCE AGAIN TYPICAL OF THIS WINTER. THE COMBINATION OF
THE UPPER RIDGE AND MODERATE NORTH TO NORTHEAST WINDS AT THE SURFACE
WILL ALLOW COAST AND COASTAL VALLEYS TO WARM UP 8 TO 15 DEGREES
TODAY...INCLUDING THE CENTRAL COAST.

THIS SYNOPTIC PATTERN WILL CHANGE LITTLE THROUGH THE WEEKEND WITH
THE RIDGE AXIS BECOMING MORE POSITIVELY TILTED INTO THE
INTERMOUNTAIN REGION. WITH A FEW MORE DEGREES OF WARMING EXPECTED ON
SAT/SUN...THERE WILL BE A GOOD CHANCE THAT SOME COAST AND VALLEY
HIGH TEMP RECORDS WILL BE BROKEN. MODELS DO INDICATE SOME HIGH
CLOUDS MOVING OVER THE AREA FRIDAY INTO SATURDAY...AND IF THE CLOUD
SHIELD THICKENS UP...THEN HIGH TEMPS COULD BE A FEW DEGREES COOLER
THAN THE CURRENT FORECAST SHOWS. HOWEVER...THIS WILL STILL ALLOW FOR
HIGH TEMPS TO BE UP NEAR 20 DEGREES WARMER THAN USUAL FOR THIS TIME
OF YEAR.

PEOPLE RUNNING IN THIS WEEKEND'S L.A. MARATHON AND 5 K RACE NEED TO
BE AWARE OF THE POTENTIAL FOR SERIOUS HEAT RELATED
PROBLEMS...ESPECIALLY AFTER MID-MORNING. A SPECIAL WEATHER STATEMENT
HAS BEEN ISSUED COVERING THE UPCOMING HEAT EVENT. (LAXSPSLOX)

.LONG TERM (SUN-WED)...

ON SUNDAY...BOTH THE GFS AND EC MODELS CONTINUE TO KEEP THE RIDGE
AXIS OVER SOCAL KEEPING THE UNSEASONABLE HIGH TEMPS OVER MUCH OF THE
FORECAST AREA. BY MONDAY...AN UPPER DISTURBANCE WILL MOVE INTO NRN
CALIFORNIA ALLOWING FOR SOME COOLING FOR AREAS N OF POINT
CONCEPTION...AND ONLY A COUPLE DEGREES OF COOLING ACROSS LA/VTU
COUNTIES. BEST COOLING WILL OCCUR ACROSS THE CENTRAL COAST. THE
RIDGE WILL FINALLY BREAK DOWN BY TUESDAY ALLOWING FOR A MORE
SIGNIFICANT COOLING TREND WITH COAST AND VALLEY HIGHS IN THE UPPER
70S AND LOWER 80S. ANOTHER UPPER LOW SHOULD MOVE OVER SOUTHERN
CALIFORNIA BY WEDNESDAY WITH MORE SIGNIFICANT COOLING DOWN INTO THE
70S. EXPECT A RETURN OF THE MARINE LAYER STRATUS FOR COASTAL AREAS
EARLY AS MONDAY OR TUESDAY.

&&

.AVIATION...12/1140Z...

AT 0815Z...THE BASE OF THE MARINE INVERSION WAS AT 200 FEET. THE TOP
OF THE INVERSION WAS AT 1300 FEET WITH A TEMPERATURE OF 20C.

EXCEPT FOR SOME STRATUS WITH IFR TO LIFR CONDS ACROSS THE INTERIOR
VLYS OF SLO AND SBA COUNTIES...THE SANTA YNEZ VALLEY...AND PORTIONS
OF THE CENTRAL COAST...CONDS WILL BE VFR THRU THE PD. THE WILL BE
LOCALLY GUSTY N TO NE WINDS THIS MORNING AND AGAIN LATE TONIGHT/FRI
MORNING ACROSS PORTIONS OF L.A. AND VTU COUNTIES...WITH LOCAL LLWS
AND MDT UDDF.

KLAX...HIGH CONFIDENCE IN THE 12Z TAF WITH VFR CONDS THROUGH THE PD.

KBUR...HIGH CONFIDENCE IN THE 12Z TAF WITH VFR CONDS THROUGH THE PD.
SOME LLWS AND MDT UDDF EXPECTED THIS MORNING THROUGH EARLY
AFTERNOON.

&&

.MARINE...12/400 AM...

FAIRLY CONFIDENT THAT SCA CONDITIONS ACROSS THE SOUTHERN TWO THIRDS
OF THE OUTER WATERS WILL WEAKEN BY MID OR LATE MORNING. THERE IS A
20 PERCENT CHANCE THAT SCA CONDITIONS WILL PERSIST THROUGH LATE
THIS EVENING.

ACROSS THE INNER WATERS...THERE IS A 30 TO 40 PERCENT CHANCE THAT
SCA CONDS WILL OCCUR FRI MORNING NEAR SHORE FROM VENTURA
SOUTH TO SANTA MONICA.
