SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
335 PM PST WED DEC 13 2006

.SHORT TERM (TONIGHT THROUGH FRI)...
SKIES REMAIN MOSTLY CLEAR...EXCEPT FOR SOME HIGH CLOUDS STREAMING
ACROSS THE REGION THIS AFTERNOON UNDER A DIRTY RIDGE OVER SO CAL.
TEMPERATURES WERE GENERALLY A FEW DEGREES WARMER THAN YESTERDAY.
DECENT NORTHERLY GRADIENTS ONCE AGAIN THIS AFTERNOON WILL LEAD TO
WIND ADVISORIES FOR THE LA/VTU/SBA MOUNTAINS AND THE SANTA BARBARA
SOUTH COAST LATE THIS AFTERNOON THROUGH THE OVERNIGHT HOURS. THE
STRONGEST WINDS WILL BE FOCUSED BELOW AND THROUGH PASSES OF SOUTHERN
SANTA BARBARA COUNTY...AS WELL AS THE LOS ANGELES AND VENTURA
COUNTY MOUNTAINS NEAR THE INTERSTATE 5 CORRIDOR. AREAS UNDER A WIND
ADVISORY CAN EXPECT FREQUENT WIND GUSTS OVER 45 MPH. THURSDAY NIGHT
INTO FRIDAY MORNING WILL ALSO SEE THE SAME TYPE OF WIND CONDITIONS
AS NORTHERLY GRADIENTS CONTINUE TO PREVAIL ACROSS THE AREA. WRF
GUIDANCE INDICATES LAX-BFL SFC GRADIENTS NEAR -5.0 MB BOTH DAYS.
SURPRISINGLY...NORTHEAST WIND SHIFT WILL NOT OCCUR THROUGH THE
PERIOD. THIS WILL HELP KEEP TEMPS A BIT COOLER THAN FIRST THOUGHT.
WRF GUIDANCE INDICATES LAX-BFL SFC GRADIENTS NEAR -5.0 MB BOTH DAYS.
AS THE RIDGE BEGINS TO FLATTEN...THICKNESS LEVELS DROP A BIT AHEAD
OF THE NEXT STORM SYSTEM WHICH WILL COOL TEMPS OFF NEARLY 5 DEGREES
IN MOST AREAS.

.LONG TERM (SATURDAY THROUGH TUESDAY)...
MAIN CONCERN IS THE DRASTIC CHANGE OF THE 12Z AND 18Z GFS AND
EUROPEAN MODEL RUNS FOR THIS WEEKENDS STORM. THE LATEST MODEL RUNS
INDICATE THAT THE TROUGH WILL NOT BE AS DEEP AS ONCE ADVERTISED. THE
CLOSED LOW IS NOW WELL TO THE EAST OVER AZ BY MON. ALTHOUGH THIS HAS
BEEN JUST A COUPLE OF RUNS...CONFIDENCE IS GREATER THAT THIS WILL
BECOME MORE OF A WIND EVENT THEN RAIN EVENT. SINCE BOTH THE EUROPEAN
AND GFS ARE IN AGREEMENT AT THIS TIME HAVE LOWERED POPS ON SATURDAY
TO JUST CHANCE. RAIN CHANCES MIGHT NEED TO BE LOWERED TO CHANCE AS
WELL ON SUNDAY. PRECIP AMOUNTS SHOULD BE LESS BASED ON THE NEW MODEL
RUNS AS SOUTHERLY FLOW IS NOT AS STRONG AS WELL. 500 MB TEMPS WILL
NOT BE QUITE AS COLD ALOFT AS TROUGH WILL NOT DIG AS FAR
SOUTH...HOWEVER DID LEAVE THUNDERSTORMS IN THE FORECAST AREA FOR
NOW. BUT LATER SHIFTS WILL HAVE TO RETHINK THIS. SUNDAY NIGHTS
TEMPS WILL COOL DOWN DRAMATICALLY ACROSS THE ANTELOPE VALLEY. IF ANY
WRAP AROUND MOISTURE FUNNELS IN FROM THE EAST...THE ANTELOPE VALLEY
COULD SEE A FEW SNOW FLURRIES SUNDAY NIGHT. SKIES SHOULD BEGIN TO
CLEAR UP BY MONDAY WITH GENERAL NW TO N FLOW ACROSS THE REGION.
TEMPS SHOULD BE WELL BELOW AVERAGE THROUGH SUNDAY...WITH GRADUAL
WARMING ON MON AND TUE. TEMPS SHOULD STILL BE BELOW OR NEAR NORMAL
BY TUE.

&&

.AVIATION...
THE REMAINING LOW CLOUDS AND FOG HAVE CLEARED OUT FROM KPRB...KSBP
AND KSMX. SKIES WILL BE MOSTLY CLEAR EXCEPT FOR MID AND HIGH CLOUDS.
WINDS WILL BE THE PRIMARY FOCUS FOR AVIATION THIS AFTERNOON THROUGH
TONIGHT WITH GUSTY WINDS AND LLWS AFFECTING THE KSBA AIRFIELD THIS
EVENING. OTHER AIRFIELDS THAT COULD BE AFFECTED THIS AFTERNOON AND
TONIGHT INCLUDE KBUR AND KVNY. OTHERWISE...LOW CLOUDS AND FOG WILL
LIKELY RETURN TO KPRB...KSBP AND KSMX. OTHER LOCATIONS ARE EXPECTED
TO REMAIN CLEAR TONIGHT.

.MARINE...
THE HIGH SURF ADVISORY HAS BEEN EXTENDED ON THE CENTRAL COAST
THROUGH THURSDAY AFTERNOON. THE COASTAL HAZARD MESSAGE FOR ABOVE
NORMAL SURF HAS ALSO BEEN EXTENDED UNTIL THURSDAY AFTERNOON FOR
LA/VENTURA COUNTIES. A BRIEF RESPITE IN THE HIGH SEAS AND RESULTANT
HIGH SURF EXPECTED TONIGHT WAS MENTIONED IN THE TEXT OF THE LATEST
HIGH SURF ADVISORY EXTENSION.

BY THURSDAY AFTERNOON...THE NEW SURGE OF THE NORTHWEST SWELL WILL
HAVE OVERTAKEN ALL OF THE OUTER COASTAL WATERS ACCORDING TO THE 12Z
RUN OF THE ENP MODEL. THE INNER WATERS WILL HAVE TO BE WATCHED
AGAIN IN CASE ENOUGH WAVE ENERGY SUCCEEDS IN REFRACTING AROUND POINT
CONCEPTION AND INTO THE INNER COASTAL WATERS. ON FRIDAY THERE MAY BE
ENOUGH SWELL TO GENERATE A HIGH SURF ADVISORY FOR MAINLY THE WEST
FACING SHORELINE SOUTH OF POINT CONCEPTION.

DUE TO THE LONG PERIOD NATURE AND THE PERSISTENTLY ABOVE NORMAL
SURF...A HIGH RIP CURRENT POTENTIAL WILL ALSO EXIST FOR MOST OF THE
WEEK.

THE HEIGHTS OF THE HIGH TIDES ARE NOT PARTICULARLY HIGH...AND DO NOT
COINCIDE WITH THE WINDIEST AND HIGHEST SEA TIMING...SO COASTAL
FLOODING IS NOT EXPECTED TO BE A CONCERN THIS WEEK. WITH THAT
SAID...THERE COULD STILL BE SOME LOCAL SPILLOVER IN PARTICULARLY
SUSCEPTIBLE LOCATIONS.

...POTENTIAL FOR A COLD PACIFIC STORM THIS WEEKEND ACROSS THE
SOUTHLAND...

A COLD STORM SYSTEM IS EXPECTED MOVE THROUGH THE EASTERN PACIFIC
FRIDAY...THEN PUSH INTO THE WESTERN UNITED STATES OVER THE WEEKEND.
THE EXACT TRACK OF THE SYSTEM...WHICH IS STILL SOMEWHAT IN
QUESTION...WILL ULTIMATELY DETERMINE ITS IMPACT ON
SOUTHWESTERN CALIFORNIA. AT THIS TIME IT APPEARS THERE IS THE
POTENTIAL FOR MODERATE AMOUNTS OF RAIN AND MOUNTAIN SNOWS ACROSS
PORTIONS OF OUR FORECAST AREA.

THE BULK OF THE PRECIPITATION ASSOCIATED WITH THE WEATHER SYSTEM
SHOULD AFFECT SOUTHWESTERN CALIFORNIA SATURDAY AFTERNOON AND EVENING
AS A COLD FRONT PUSHES THROUGH THE REGION. THE THREAT OF
THUNDERSTORMS WITH SMALL HAIL ALSO EXISTS WITH THIS SYSTEM LATE
SATURDAY AND SATURDAY NIGHT. A MOIST AND UNSTABLE AIRMASS BEHIND THE
FRONT SHOULD LINGER OVER THE AREA SUNDAY WITH THE CHANCE OF SHOWERS
EXPECTED THROUGH THE DAY. PRELIMINARY RAINFALL ESTIMATES WITH THIS
SYSTEM FROM SATURDAY THROUGH SUNDAY IS FOR ONE QUARTER TO ONE HALF
INCH ACROSS MUCH OF THE AREA...WITH LOCAL AMOUNTS AROUND ONE INCH
ACROSS HIGHER TERRAIN AND WHERE ANY THUNDERSTORMS OCCUR.

IT APPEARS THE SNOW LEVELS ASSOCIATED WITH THE MAIN FRONTAL BAND
WILL RANGE BETWEEN 3000 AND 4000 FEET...WITH SNOW LEVELS POSSIBLY
LOWERING TO AS LOW AS 2500 FEET BEHIND THE FRONT LATE SATURDAY NIGHT
INTO SUNDAY MORNING. THESE LOW SNOW LEVELS WOULD CERTAINLY AFFECT
MANY OF THE MOUNTAIN PASSES AND POSSIBLY PORTIONS OF THE ANTELOPE
VALLEY. SEVERAL INCHES OF SNOW WILL BE POSSIBLE DURING THE WEEKEND
ESPECIALLY ABOVE 3000 FEET. THOSE TRAVELING INTO THE MOUNTAINS THIS
WEEKEND ARE ENCOURAGED TO MONITOR THE LATEST FORECASTS AND ANY
POTENTIAL WINTER WEATHER ADVISORY OR WINTER STORM WATCH OR WARNING
PRODUCTS.

THIS MAY BE THE FIRST SIGNIFICANT WINTER-LIKE STORM OF THIS SEASON
OVER SOUTHWESTERN CALIFORNIA. PEOPLE PLANNING OUTDOOR ACTIVITIES...
ESPECIALLY IN THE MOUNTAINS...SHOULD BE PREPARED FOR
THE INCLEMENT WEATHER.
