SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1055 PM PDT WED OCT 28 2009

...UPDATED AVIATION SECTION...

.SYNOPSIS...
A HIGH PRESSURE SYSTEM OFF THE CALIFORNIA COAST WILL SLOWLY NUDGE
INTO OUR AREA THURSDAY AND FRIDAY...WITH WEAK OFFSHORE WINDS EXPECTED.
TEMPERATURES WILL GRADUALLY WARM UP THURSDAY AND FRIDAY...WITH
WARMER THAN NORMAL TEMPERATURES EXPECTED OVER THE WEEKEND AND INTO
EARLY NEXT WEEK.

&&

.SHORT TERM (TONIGHT-SAT)...MOSTLY CLEAR SKIES WITH JUST A FEW HI
CLOUDS AT TIMES COVERED THE REGION THIS EVENING...AND THIS WILL
CONTINUE THRU TONIGHT. STRONG AND GUSTY NORTHWEST TO NORTHEAST
CANYON WINDS WILL PREVAIL OVERNIGHT FROM THE SBA COUNTY S COAST AND
MOUNTAINS TO THE MOUNTAINS OF VTU/L.A. COUNTIES...WHERE WIND
ADVISORIES ARE IN EFFECT. LOCAL GUSTY NORTH TO NORTHEAST WINDS WILL
PREVAIL OVER MANY OTHER PARTS OF THE DISTRICT OVERNIGHT AS WELL.
WITH THE COOL DRY AIRMASS OVER THE REGION...THERE WILL BE THE
POSSIBILITY OF FROSTS AND FREEZES LATE TONIGHT INTO THU MORNING OVER
SOME OF THE INTERIOR VALLEYS AND ANTELOPE VALLEY...ESPECIALLY WHERE
WINDS ARE LIGHT TO CALM. PLEASE SEE LAXNPWLOX FOR DETAILS ON THE
WIND ADVISORIES AND FROST AND FREEZING CONDITIONS.

A LARGE UPPER LEVEL LOW AND UPPER TROF OVER THE GREAT BASIN TONIGHT
WILL MOVE FAIRLY QUICKLY EAST THU THRU FRI. THIS WILL ALLOW AN UPPER
LEVEL RIDGE OVER THE EASTERN PACIFIC TO BUILD INTO CENTRAL CA BY
FRI. THE UPPER LEVEL RIDGING WILL THEN LINGER OVER CENTRAL AND
SOUTHERN CA FRI NIGHT AND SAT. DRY WEATHER WILL CONTINUE ACROSS THE
REGION THROUGH SAT...WITH MOSTLY CLEAR SKIES IN ALL AREAS. IT LOOKS
LIKE THE NORTH TO NORTHEAST WINDS WILL DIMINISH BY THU MORNING WITH
JUST MAINLY WEAK NIGHT AND MORNING OFFSHORE FLOW POSSIBLE THU NIGHT
INTO SAT. TEMPS OVER THE REGION WILL BE A FEW DEGREES BELOW NORMAL
ON THU...THEN WARM TO SEVERAL DEGREES ABOVE NORMAL FOR MOST AREAS BY
SAT.

...FROM PREVIOUS DISCUSSION...

.LONG TERM (SUN-WED)...A WEAK FRONT SHOULD PASS THROUGH THE STATE
SAT NIGHT...WHICH WILL WEAKEN THE HIGH OFF THE COAST. ONCE IT PASSES
THROUGH ON SUN HOWEVER...THE HIGH WILL HAVE A CLEAR PATH TO PUSH
RIGHT OVER CA. OFFSHORE GRADS ALSO INCREASE SLIGHTLY WITH SOME COLD
AIR PUSHING INTO THE INTERIOR WEST. THIS ALL ADDS UP TO CONTINUED
WARMING ON SUN AND MON. 80S SHOULD BE FAIRLY COMMON OVER MOST OF THE
REGION...WITH THE VALLEYS GETTING CLOSE TO THE 90S. COOLING TREND
STILL LOOKS GOOD FOR TUE AND WED...AS LONG RANGE MODELS CONTINUE TO
SHOW A DEEP TROUGH FORMING SOUTH OF ALASKA...WHICH WOULD FORCE THE
HIGH TO THE EAST AND INCREASE ONSHORE GRADS.

STILL KEEPING THE FORECAST MOSTLY FREE OF LOW CLOUDS AND FOG.
CURRENT SYNOPTIC PATTERN SUPPORTS THIS...BUT IN ALL LIKELIHOOD THE
MARINE LAYER WILL THROW A CURVE BALL SOMETIME OVER THE NEXT WEEK.
ONCE SOME FOG FORMS...IT SHOULD BE OF THE DENSE VARIETY AND STICK
AROUND NEAR THE COAST...BUT WILL PROBABLY BE RANDOM IN COVERAGE. AS
A RESULT...WILL HAVE TO WAIT AND SEE WHEN/IF THIS HAPPENS.

&&

.AVIATION...29/0600Z...
HI CONFIDENCE IN CAVU CONDITIONS AT ALL AIRFIELDS. MODERATE
CONFIDENCE IN TIMING/STRENGTH OF WINDS. NORTH TO NORTHEAST WINDS WILL
PERSIST THROUGH THE MORNING...PARTICULARLY GUSTY ACROSS
KBUR...KVNY...KSBA...AND KLAX. LOW LEVEL WIND SHEAR LIKELY AT KSBA
THROUGH 10-12Z. OTHERWISE...NO ISSUES EXPECTED.

KLAX...HI CONFIDENCE IN CURRENT TAF...WITH ONLY UNCERTAINTY IN
TIMING OF WIND DIRECTION SHIFT TO THE NE/E. SHOULD BE WITHIN AN HOUR
OF FORECAST THOUGH.

KBUR...HI CONFIDENCE IN THE CURRENT TAF.
