SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
835 PM PST SUN NOV 11 2007

.SHORT TERM (TONIGHT-WEDNESDAY)...A WEAK UPPER LEVEL LOW PRESSURE SYSTEM
CENTERED OVER LOS ANGELES COUNTY WILL CONTINUE TO DIG SOUTHWARD OVERNIGHT...
RESULTING IN INCREASING NORTH TO NORTHEAST FLOW ALOFT IN THE WAKE OF
THE SYSTEM. CURRENT RADAR IMAGERY AND OBSERVATIONAL DATA SHOWING
MOST OF THE RAINFALL HAS ENDED ACROSS THE REGION WITH THE EXCEPTION
OF SOME SHOWER ACTIVITY ACROSS THE NORTH SLOPES OF THE MOUNTAINS AND
ANTELOPE VALLEY. THESE LOCATIONS ARE EXPECTED TO RECEIVE SCATTERED
TO ISOLATED SHOWER COVERAGE OVERNIGHT DUE TO THE PROXIMITY OF THE
WRAP AROUND MOISTURE.

THE MAIN SHORT TERM CONCERN WILL BE INCREASING WINDS ACROSS THE DISTRICT.
INITIALLY...THE STRONGEST WINDS WILL BE FOCUSED THROUGH THE NORTH-SOUTH
FACING PASSES AND CANYONS OF THE SANTA YNEZ RANGE AND INTERSTATE 5
CORRIDOR. AFTER MIDNIGHT...THE FLOW IS EXPECTED TO BECOME MORE
NORTHEASTERLY...WITH WINDS BECOMING MORE WIDESPEAD BELOW AND THORUGH
PASSES AND CANYONS OF LOS ANGELES AND VENTURA COUNTIES. WIND ADVISORY
HAS BEEN POSTED FOR THE MOUNTAINS OF SANTA BARBARA...VENTURA...AND
LOS ANGELES COUNTIES...AS WELL AS THE PASSES AND CANYONS OF THE
SANTA BARBARA COUNTY SOUTH COAST. MAIN CONCERN TONIGHT WILL BE A
STRONG NORTHERLY JET OF AROUND 120 KNOTS...CURRENTLY APPROACHING
SANTA BARBARA COUNTY THAT WILL TRACK EASTWARD ACROSS VENTURA AND
LOS ANGELES COUNTIES OVERNIGHT. IN ADDITION...LATEST WRF INDICATED
850 MB WIND SPEEDS BETWEEN 40 AND 50 KNOTS OVERNIGHT...ALONG WITH
INCREASING LOW LEVEL OFFSHORE GRADIENTS. THIS WILL LIKELY TRANSLATE
INTO WIND GUSTS UP TO AT LEAST 55 MPH IN FAVORED PASSES AND CANYONS...
WITH LATER SHIFTS POSSIBLY NEEDING TO UPGRADE TO A HIGH WIND WARNING
FOR LA COUNTY MOUNTAINS. WHILE THE STRONGEST WINDS ARE EXPECTED TO
OCCUR IN THE MOUNTAINS...IT DOES APPEAR THAT GUSTY NORTH TO NORTHEAST
WINDS WILL GRAUDALLY SURFACE INTO THE VALLEYS AND EVEN SOME COASTAL
AREAS LATER TONIGHT AND MONDAY MORNING. AS A RESULT...HAVE BUMPED
UP WIND SPEEDS A BIT IN EVENING UPDATE FOR THE COAST AND VALLEYS
OF LA/VTU COUNTIES...WITH LATER SHIFTS POSSIBLY NEEDING TO EXPAND
THE WIND ADVISORY FOR SOME OF THESE LOCATIONS.

OTHER SHORT TERM CONCERN WILL BE RADIATIONAL FOG DUE TO THE LINGERING
LOW LEVEL MOISTURE AND LIGHTER WINDS...MAINLY NORTH OF POINT CONCEPTION.
HAVE INTRODUCED PATCHY DENSE FOG FOR MOST LOCATIONS NORTH OF POINT
CONCEPTION TONIGHT.

THE OFFSHORE FLOW WILL BRING SIGNIFICANT WARMING TO THE REGION
ON MONDAY...WITH ADDITIONAL WARMING EXPECTED ON TUESDAY. MANY
COASTAL AND VALLEY LOCATIONS ARE EXPECTED TO SOAR WELL INTO THE
80S ON TUESDAY.  CONTINUED WARM AND DRY ON WEDNESDAY.

*** LONG TERM FROM PREVIOUS DISCUSSION ***

.LONG TERM (THURSDAY-SUNDAY)...AN INTERMITTENT ONSHORE/OFFSHORE
PATTERN SHOULD CONTINUE TO OCCUR FOR LATE WEEK AND THROUGHOUT THE
WEEKEND...AS A SERIES OF WEAK SYSTEMS CONTINUES TO PUSH SOUTH
FROM THE NORTHWEST. AT THIS TIME...NO REAL THREAT FOR
PRECIPITATION EXISTS EXCEPT FOR AREAS NORTH OF POINT CONCEPTION.
WITH MODEL PERFORMANCE POOR AT THE CURRENT TIME...BEST APPROACH
IS TO TAKE CONSERVATIVE APPROACH...MENTIONING NO PRECIPITATION
AND ONLY INCREASING CLOUDINESS.

&&

.AVIATION...AT 0415Z...INCREASING NORTHERLY FLOW STARTING TO BREAK
UP THE LOW LEVEL MOISTURE ACROSS THE REGION...SO CLOUD COVERAGE
EXPECTED TO BE QUITE CHAOTIC DURING NEXT FEW HOURS. OVERALL...THE
TRENDS ARE FOR LESS CLOUDS OVERNIGHT ACROSS TAF LOCATIONS SOUTH OF
POINT CONCEPTION...WITH THE EXCEPTION OF KWJF AND KPMD. WILL
HAVE TO CLOSELY MONITOR KSBP...KSMX...AND KPRB FOR POTENTIAL
DENSE FOG.

.KLAX...SCT-BKN CONDITIONS LIKELY TO CONTINUE AT KLAX FOR MUCH OF
NIGHT. FOR NEXT FEW HOURS...WILL HAVE TO BE CONCERNED WITH LIFR
CONDITIONS DUE TO RADIATIONAL FOG. AS DRIER NORTHEAST FLOW PREVAILS
LATER TONIGHT AND MONDAY...SHOULD CONTINUE TO SEE DECREASING TREND
IN CLOUDS AND IMPROVED VISIBILITIES. THERE IS A CHANCE THAT SOME NORTH
TO NORTHEAST WINDS WILL AFFECT KLAX LATER TONIGHT...BUT ARE GENERALLY
EXPECTED TO REMAIN UNDER 10 KT.

.KBUR...SCT-BKN CONDITIONS LIKELY TO CONTINUE AT KLAX FOR MUCH OF
NIGHT. FOR NEXT FEW HOURS...WILL HAVE TO MONITOR FOR POTENTIAL
LOW VSBYS IN RADIATIONAL FOG. AS DRIER NORTHEAST FLOW PREVAILS
LATER TONIGHT AND MONDAY...SHOULD CONTINUE TO SEE DECREASING TREND
IN CLOUDS AND IMPROVED VISIBILITIES. THERE IS A CHANCE THAT SOME NORTH
TO NORTHEAST WINDS WILL AFFECT KBUR LATER TONIGHT...BUT ARE GENERALLY
EXPECTED TO REMAIN UNDER 10 KT. HOWEVER...NEXT TAF PACKAGE WILL INCLUDE
SOME LLWS DUE TO POTENTIAL STRONGER WINDS ABOVE SURFACE.
