...GUSTY NORTH TO NORTHEAST WINDS WILL AFFECT PORTIONS OF LOS
ANGELES AND VENTURA COUNTIES...

.NORTHEAST WINDS THAT AFFECTED PORTIONS OF LOS ANGELES AND VENTURA
COUNTIES EARLIER THIS MORNING HAVE WEAKENED...BUT ARE EXPECTED TO
RESTRENGTHEN AFTER THIS EVENING. A WINTER STORM SYSTEM OVER
NORTHERN NEVADA WILL SLIDE SOUTHWARD INTO EASTERN CALIFORNIA
OVERNIGHT. THIS SYSTEM WILL BRING MODERATE NORTHERLY FLOW ALOFT
AND ALLOW SURFACE HIGH PRESSURE TO BUILD OVER UTAH. THE
COMBINATION OF THESE TWO FACTORS WILL ALLOW GUSTY NORTH TO
NORTHEAST FLOW TO RETURN TO THE MOUNTAINS OF LOS ANGELES AND
VENTURA COUNTIES AS WELL AS THE SANTA CLARITA VALLEY AFTER
MIDNIGHT. THE WINDS WILL LIKELY SPREAD INTO THE REMAINDER OF THE
VALLEYS OF LOS ANGELES AND VENTURA COUNTIES SOMETIME TUESDAY
MORNING...WHICH MAY REQUIRE THE EXTENSION OF THE WIND ADVISORY FOR
SOME OF THOSE LOCATIONS. GUSTY NORTH TO NORTHEAST WINDS ARE
EXPECTED TO CONTINUE THROUGH THE EARLY AFTERNOON HOURS...DIMINISHING
BELOW ADVISORY CRITERIA AFTER 3 PM.

SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
409 AM PST MON DEC 10 2007

.SHORT TERM...MID AND HIGH LVL CLOUDS RACING ACROSS THE AREA THIS
MORNING...FORCED SSWWD BY STRONG N TO NELY FLOW ALF. MOST OF THESE
CLOUDS SHOULD BE GONE BY DAYBREAK...SO WILL GO WITH A MOSTLY SUNNY
DAY. GUSTY WINDS WERE ALREADY OCCURRING IN THE MTNS OF L.A. AND VTU
COUNTIES...AND LOCALLY IN THE VLYS. WITH SOME MODERATE SUBSIDENCE
SPREADING ACRS THE AREA...XPCT WINDS TO BECOME A BIT MORE WIDESPREAD
THIS MORNING...AND WINDS SHOULD INCREASE TO NEAR OR JUST ABOVE
ADVISORY LEVELS IN THE MTNS OF VTU AND L.A. COUNTIES...INCLUDING THE
SANTA MONICA RANGE...AND IN THE SANTA CLARITA VALLEY. ACROSS THE
REST OF THE L.A./VTU COUNTY VALLEYS...XPCT WINDS TO REMAIN BELOW
ADVISORY LEVELS. TEMPS WILL REMAIN SEVERAL DEGREES BELOW NORMAL
ACROSS THE AREA TODAY.

MODELS SHOW STRONG SHORT WAVE ENERGY DROPPING SOUTH SOUTHWESTWARD
FROM THE NRN ROCKIES...FORMING AN UPPER LOW OVER NEVADA TONIGHT. THE
LAST TWO RUNS OF THE GFS ARE QUITE A BIT FARTHER W WITH THE TRACK OF
THIS UPPER LOW...BRINGING IT JUST TO THE E OF THE FCST AREA BY LATE
TUE MORNING. THE 06Z RUN ACTUALLY SHOWS SOME MEASURABLE PRECIP
ACROSS ERN SXNS OF THE FCST AREA FOR TUE. THE WRF IS FARTHER E WITH
THE UPPER LOW...WITH STRONGER NLY TO NELY FLOW ALOFT AND BETTER
SUBSIDENCE ACROSS THE AREA FOR TUE...WHICH WOULD YIELD A DRIER AND
WINDIER SOLUTION. THE ECMWF IS FARTHER E THAN BOTH MODELS. AT THIS
TIME...WILL CONTINUE WITH THE CURRENT FCST FOR DRY CONDITIONS ON
TUE...WITH AN INCREASE IN COVERAGE AND STRENGTH OF THE GUSTY NELY
WINDS ACROSS L.A. AND VTU COUNTIES. IF THE WRF IS CORRECT...IT LOOKS
AS THOUGH AT LEAST ADVISORY LEVEL WINDS WOULD OCCUR IN THE MTNS AND
VLYS OF L.A. AND VTU COUNTIES...POSSIBLY SPREADING INTO PORTIONS OF
THE COASTAL PLAIN. OF COURSE...IF THE GFS SOLN IS CORRECT...IT WOULD
BE LESS FAVORABLE FOR WIND...BUT MORE CLOUDS AND POSSIBLY LOW CHANCE
POPS WOULD HAVE TO BE ADDED TO THE FCST. SATELLITE TRENDS LATER
TODAY SHOULD HELP DECIDE WHICH MODEL HAS A BETTER HANDLE ON THE
SYSTEM. WHERE WINDS REMAIN LIGHT...FROST IS POSSIBLE TONIGHT...AND
IT COULD BE WDSPRD ENOUGH ON THE CENTRAL CST TO WARRANT FROST
ADVISORIES. TUE WILL BE ANOTHER VERY COOL DAY ACROSS THE AREA...WITH
TEMPS DOWN AT LEAST A COUPLE OF DEGREES FROM TODAY.

THE UPPER LOW WILL BEGIN TO PULL EWD TUE NIGHT AND WED. ANOTHER
UPPER SYSTEM MOVES INTO THE ERN PAC LATE WED...BUT WHILE THE WRF
BRINGS IT INTO CENTRAL CA...THE GFS FORMS A CUTOFF LOW AND DROPS IT
SWD WELL TO THE W OF THE AREA. LOW LVL FLOW WILL REMAIN FAIRLY
STRONG FROM THE NE...BUT WILL GRADUALLY WKN WED AFTERNOON. STILL
XPCT GUSTY WINDS IN THE MTNS AND VALLEYS OF L.A. AND VTU COUNTIES
AND IN SOME CSTL SXNS LATE TUE NIGHT AND WED MORNING. SHOULD BE
ANOTHER VERY COOL DAY ACROSS THE REGION...WITH JUST SOME HIGH
CLOUDINESS FROM TIME TO TIME.

.LONG TERM...THE 06Z RUN OF THE GFS TAKES THE UPPER LOW AND DROPS IT
SLOWLY SWD WELL OFF THE CST TO OFF NRN BAJA BY SAT...WITH BROAD WKLY
CYCLONIC NWLY FLOW ALF ACROSS THE AREA. THE ECMWF AND THE WRF BOTH
TAKE THE UPPER LOW FROM CENTRAL CA AND DROP IT SWD ACRS THE AREA WED
NIGHT...THEN THE ECMWF SHOWS NWLY FLOW WITH RISING HEIGHTS ACROSS
THE AREA THU AND FRI. WITH SO MUCH UNCERTAINTY IN THE DETAILS OF THE
UPPER PATTERN...WL NOT MAKE MANY CHANGES TO THE EXTENDED...SINCE
EITHER WAY...IT LOOKS DRY THROUGH SUN. TEMPS MAY INCH UPWARD THU AND
FRI...BUT SHOULD STAY A BIT BELOW NORMAL. AND...IF ANY WARMING DOES
OCCUR...A TROUGH MOVING INTO THE W CST SHOULD BRING COOLING AGAIN
OVER THE WEEKEND. LOOKS LIKE THERE MAY BE A CHANCE OF RAIN ACROSS
THE AREA BY EARLY NEXT WEEK.

.AVIATION...

10/1200Z

ONLY A FEW CIRRUS CLOUDS WILL DRIFT OVERHEAD IN THE NE FLOW ALOFT.
OFFSHORE FLOW AT THE SURFACE WILL CREATE LOCAL LLWS AND TURBULENCE
IN AND AROUND THE HIGHER TRRN.

.KBUR...VERY HIGH CONFIDENCE IN CAVU CONDS. WIND DIRECTION WILL VARY
THROUGH THE DAY AS NE FLOW FIGHTS WITH SOUTHERLY SEABREEZE. LLWS
