SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
905 PM PST THU FEB 12 2009

.SHORT TERM (TONIGHT-SUN)...WINDS HAVE DIMINISHED IN MOST AREAS THIS
EVENING. QUIET WX FOR THE MOST PART COVERED THE REGION WITH SOME
CLOUDINESS BEGINNING TO PUSH INTO SLO/SBA COUNTIES. AS A COLD FRONT
OVER THE E PAC APPROACHES THE CENTRAL COAST OVERNIGHT...MORE
CLOUDINESS AND A SLIGHT CHANCE OF SHOWERS IS EXPECTED OVER SLO/SBA
COUNTIES LATE TONIGHT. ELSEWHERE PARTLY CLOUDY SKIES SHOULD PREVAIL
OVERNIGHT.

AN UPPER TROF WILL DIG DOWN THE W COAST LATE TONIGHT AND INTO
CENTRAL AND SRN CA ON FRI. THIS SYSTEM WILL BRING A FAST MOVING COLD
FRONT THROUGH THE FORECAST AREA DURING THE DAY FRI WITH RAIN AND
MOUNTAIN SNOW EXPECTED OVER THE REGION...ALONG WITH GUSTY S WINDS IN
THE MOUNTAINS. RESIDUAL MOISTURE WILL PERSIST OVER THE REGION FRI
NIGHT WITH PRECIPITATION DIMINISHING TO SHOWERS OVERNIGHT. IT LOOKS
LIKE DECENT AMOUNTS OF RAINFALL WILL FALL OVER THE REGION...WITH
ABOUT ONE HALF INCH FOR THE COAST AND VALLEYS...AND UP TO AN INCH IN
THE MOUNTAINS. SNOW LEVELS WILL FALL TO 3500 TO 4000 FEET FRI
AFTERNOON...AND GENERALLY 3000 TO 3500 FEET FRI NIGHT...WITH
MODERATE TO OCCASIONALLY HEAVY SNOW POSSIBLE IN THE SBA/VTU/L.A.
MTNS. AS A RESULT...A WINTER STORM WATCH WAS ISSUED FOR THE
MOUNTAINS FROM LATE FRI MORNING THROUGH LATE FRI NIGHT. MOST OF THE
SNOWFALL MAY OCCUR BY FRI EVENING WITH SOME ADDITIONAL ACCUMULATION
FRI NIGHT. IT LOOKS LIKE THERE WILL BE THE POTENTIAL FOR 5 TO 10
INCHES OF SNOW IN THE SBA COUNTY MTNS...AND 6 TO 12 INCHES IN THE
VTU/L.A. COUNTY MOUNTAINS...ESPECIALLY ABOVE 4000 TO 4500 FEET. THE
SNOW WILL LIKELY AFFECT TRAVEL OVER THE GRAPEVINE FRI AFTERNOON AND
FRI NIGHT. PLEASE SEE LAXWSWLOX FOR DETAILS ON THE WINTER STORM
WATCH.

THERE MAY BE A FEW SHOWERS AND MOUNTAIN SNOW SHOWERS ON SAT AND SAT
NIGHT...BUT ANY PRECIP SHOULD BE LIGHT. A LARGE AND DEEP UPPER LEVEL
TROF IS FORECAST TO DEVELOP OFF THE W COAST SAT NIGHT AND SUN...
WITH A SLOW MOVING FRONT EXPECTED TO EDGE TOWARD THE CENTRAL COAST.
THE MODELS HAVE SCALED BACK ON THE TIMING OF THE PRECIP OVER THE
DISTRICT...WITH THE WRF BRINGING VERY LITTLE RAIN TO L.A. COUNTY
THRU SUN NIGHT. THE EARLIER RUN OF THE ECMWF DID BRING THE RAIN INTO
THE DISTRICT ON SUN. WILL NOT MAKE ANY WHOLESALE CHANGES TO THE
FORECAST AT THIS TIME AS THE MODELS ARE STILL NOT IN VERY GOOD
AGREEMENT THRU SUN. PERHAPS WITH THE 00Z ECMWF CONFIDENCE MAY
INCREASE. IT STILL LOOKS LIKE THE DISTRICT WILL WIND UP WITH SOME
SIGNIFICANT RAINFALL AND MOUNTAIN SNOW EVENTUALLY FROM THIS
SYSTEM...IF NOT SUN THEN LATER SUN NIGHT AND MON.

...FROM PREVIOUS DISCUSSION...

.LONG TERM (MON-THU)...CONFIDENCE RATHER LOW FOR NEXT WEEK, BUT
MODELS HAVE BEEN TRENDING WEAKER WITH THE NEXT SYSTEM FOR TUE.
TIMING IS ALSO A BIG QUESTION MARK AT THIS POINT. STILL LOOKS LIKE A
DECENT CHANCE OF SHOWERS TUE, BUT AFTER THAT BOTH MODELS START TO
DRY THINGS OUT AND RAIN CHANCES HAVE BEEN LOWERED FOR WED AND NO
RAIN EXPECTED THU.

&&

.AVIATION...13/0500Z.
NORTH OF POINT CONCEPTION...SKIES WILL CLOUD UP AGAIN OVERNIGHT AS
THE NEXT COLD FRONT SWEEPS INTO THE AREA BRINGING LOWERING CEILINGS
AND VISIBILITY IN RAIN BY MIDDAY FRIDAY.

SOUTH OF POINT CONCEPTION...CLEAR SKIES WILL CONTINUE THROUGH MUCH
OF THE NIGHT. CLOUDS WILL LOWER AND THICKEN ON FRIDAY AS ANOTHER
COLD FRONT DIVES SOUTHEAST ACROSS THE AREA...PRODUCING RAIN BY LATE
IN THE DAY.

KLAX AND KBUR...GOOD CONFIDENCE IN MOSTLY CLEAR SKIES THROUGH
TONIGHT BEFORE CLOUDS LOWER AND THICKEN ON FRIDAY WITH A CHANCE OF
PRECIPITATION BY LATE AFTERNOON.
