KITTELL

SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1043 AM PDT FRI OCT 30 2015

.SYNOPSIS...

SANTA ANA CONDITIONS WILL BE FOCUSED OVER LOS ANGELES AND VENTURA
COUNTIES TODAY NEAR THE MOUNTAINS AND FOOTHILLS. CLEAR SKIES AND
ABOVE NORMAL TEMPERATURES EXPECTED TODAY AND TOMORROW. TEMPERATURES
WILL COOL SUNDAY AND CONTINUE COOLING NEXT WEEK AS A COLD LOW
PRESSURE SYSTEM MOVES INTO THE AREA BRINGING RAIN CHANCES AND
STRONG WINDS MONDAY THROUGH THURSDAY.

&&

.SHORT TERM (TODAY-SUN)...

100 KT NORTHERLY JET ALOFT HAS MOVED LITTLE OVER THE LAST 12
HOURS...BOOSTING THE NORTHERLY PRESSURE GRADIENT AT THE SURFACE TO
BRING GUSTY TO STRONG NORTH TO NORTHEAST WINDS TO LARGE PORTIONS OF
OUR REGION. THE STRONGEST WINDS REMAIN IN THE SAN GABRIEL AND SANTA
MONICA MOUNTAINS...WHERE GUSTS IN THE 50S AND 60S CONTINUE. VALLEY
AND COASTAL AREAS ARE SEEING GUSTY WINDS AS WELL...WITH LEO CARRILLO
STATE BEACH CHECKING IN WITH GUSTS AT 48 MPH THIS HOUR. SBA AND SLO
COUNTIES ARE ALSO SEEING WIND GUSTS IN THE 20S AND 30S IN SELECT
AREAS...INCLUDING THE AREA AROUND THE GIBRALTAR FIRE. THE WATER
VAPOR SATELLITE PICTURES ARE INDICATING THE JET NOW STARTING TO MOVE
MORE SWIFTLY TO THE EAST...AND BY ALL INDICATIONS THE WINDS SHOULD
RELAX SOME IN THE AFTERNOON. THE WEAKENING WILL START CLOSEST TO THE
COAST AND WORK INLAND THROUGH THE DAY. EXTENDED THE VALLEY AND
MOUNTAIN WIND ADVISORIES TO 3 PM TO ALIGN BETTER WITH THIS THINKING.
THE WIND WARNINGS STILL LOOK GOOD TO EXPIRE AT NOON...BUT WILL
LIKELY NEED TO BE REPLACED WITH WIND ADVISORIES THROUGH AT LEAST THE
AFTERNOON. THE SAN GABRIEL VALLEY WINDS HAVE NOT MATERIALIZED...AND
WHILE SOME ISOLATED GUSTS IN THE FOOTHILLS ARE LIKELY AROUND
NOON...THE VAST MAJORITY WILL BE WELL UNDER ADVISORY. TEMPERATURE
FORECAST FOR TODAY LOOKS GOOD...BUT MADE A FEW MINOR TWEAKS MAINLY
TO WARM THE COASTAL AREAS A TAD.

***FROM PREVIOUS DISCUSSION***

AN OFFSHORE FLOW PATTERN WILL PERSIST INTO SATURDAY...THOUGH WEAKER
THAN TODAY...AND BRING A WARMING TREND INTO HALLOWEEN WITH CONTINUED
DRY CONDITIONS ACROSS THE AREA. TEMPERATURES WILL LIKELY BE ABOUT
TEN DEGREES ABOVE NORMAL SATURDAY. BREEZY TO LOCALLY WINDY
CONDITIONS MAY PERSIST INTO SATURDAY...ESPECIALLY THROUGH AND BELOW
PASSES AND CANYONS.

THE RIDGE AXIS WILL MOVE EAST ON SATURDAY NIGHT AND INTO SUNDAY AND
COMMENCE A COOLING TREND THAT WILL BECOME MORE PRONOUNCED INTO NEXT
WEEK AS A COLD TROUGH OF LOW PRESSURE MOVES SOUTH INTO THE REGION.

.LONG TERM (MON-THU)...

A COLD FRONT ASSOCIATED WITH THE TROUGH OF PRESSURE WILL SWEEP INTO
THE AREA ON MONDAY AND BRING MUCH COOLER...CLOUDY...AND UNSETTLED
WEATHER. A PERIOD OF RAIN LOOKS TO MOVE INTO THE AREA BETWEEN MONDAY
AND MONDAY NIGHT...ESPECIALLY NORTH OF POINT CONCEPTION. POPS HAVE
BEEN INCREASED FOR MONDAY AND MONDAY NIGHT. MODEL SOLUTIONS SUGGEST
POSSIBLE MOISTURE SNEAKING INTO THE SOUTHLAND POSSIBLY BRINGING A
PERIOD OF RAIN AS WELL FOR MONDAY. GUSTY NORTHERLY WINDS WILL LIKELY
DEVELOP ACROSS SOUTHERN SANTA BARBARA COUNTY AND THROUGH INTERSTATE
5 CORRIDOR LOOK TO DEVELOP BETWEEN MONDAY AND TUESDAY.

THE TROUGH OF LOW PRESSURE WILL LINGER AND LIKELY GET REINFORCED
WITH ADDITIONAL COLD SHOTS OF AIR. THE AIR MASS WILL COOL AND TURN
MORE CONVECTIVE BETWEEN TUESDAY AND THURSDAY. GFS SOLUTIONS ARE THE
MOST AGGRESSIVE WITH THE SYSTEM...LINGERING IT INTO THURSDAY WITH A
-25 DEGREE CELSIUS 500 MB COLD POCKET MOVING SOUTH INTO THE SANTA
MONICA BAY ON WEDNESDAY. MENTIONS OF THUNDERSTORMS MAY NEED TO BE
ADDED BY FUTURE SHIFTS IF THIS FEATURE PERSISTS.

&&

.AVIATION...30/1800Z...

MID/UPPER LEVEL RIDGE OF HIGH PRESSURE CENTERED UPSTREAM WILL MOVE
OVER THE AREA. UPPER LEVEL STRONG NORTH WINDS WILL BECOME MODERATE
NORTHWEST AFTER 31/05Z WHILE MID LEVEL MODERATE NORTH WINDS WILL
PREVAIL. MIXED WEAK ONSHORE PRESSURE GRADIENT AND MODERATE OFFSHORE
GRADIENT THROUGH 31/02Z AND AFTER 31/21Z OTHERWISE MODERATE OFFSHORE
GRADIENT. A WEAK CAPPING MARINE INVERSION WAS APPROXIMATELY 1KFT AND
LOW CLOUD FIELD WAS 250 MILES OFFSHORE. THE INVERSION WILL DIFFER
LITTLE SATURDAY.

MARINE LAYER AT LAX AT 1500Z IS 978 FEET DEEP AND THE INVERSION TOP
IS AT 2618 FEET WITH A TEMP OF 27.7 DEGREES C.

KLAX...VIRTUALLY CERTAIN CURRENT SKY/VSBY CONDITIONS WILL PERSIST.
THERE IS A CHANCE LLWS WILL CONTINUE THROUGH 30/20Z.

KBUR...VIRTUALLY CERTAIN CURRENT SKY/VSBY CONDITIONS WILL PERSIST.
THERE IS A CHANCE LLWS WILL CONTINUE THROUGH 30/19Z.

LIKELY            - 60-80%
CHANCE            - 30-60%
VERY UNLIKELY     - 20% OR LESS

&&

.MARINE...30/900 AM...

SCA ADVISORY CONDITIONS WILL LIKELY END AT NOON FOR THE NORTHWEST
WINDS FROM PIEDRAS BLANCAS TO SAN CLEMENTE ISLAND AS WELL AS THE
NORTHEAST WIND FROM POINT MUGU TO SANTA MONICA. OTHERWISE THERE IS A
SLIGHT CHANCE OF COMBINED SEAS PERSISTING AT OR OVER 10 FEET FROM
PIEDRAS BLANCAS TO POINT SAL 10-60 NM THROUGH EARLY AFTERNOON BUT AS
THE WINDS DIMINISH THE LOCALLY GENERATED SEAS WILL SUBSIDE.
NORTHWEST WINDS WILL LIKELY INCREASE EARLY MONDAY MORNING AND THERE
IS A CHANCE GALE FORCE WINDS WILL EXIST OVER THE ENTIRE AREA MONDAY

BETWEEN 1100 AND 1145 AM. TIDE HEIGHTS WILL BE BETWEEN 7 AND 7.5
