SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1026 AM PST SUN DEC 11 2011

.SYNOPSIS...
A COLD LOW PRESSURE SYSTEM WILL DROP ALONG THE SOUTHWEST CALIFORNIA
COAST BY MONDAY AND BRING A DECENT CHANCE OF VALLEY RAIN AND
MOUNTAIN SNOW...MAINLY FOR SECTIONS SOUTH OF POINT CONCEPTION. THERE
WILL BE A SLIGHT CHANCE OF THUNDERSTORMS MONDAY AFTERNOON THROUGH
TUESDAY MORNING. SKIES WILL START TO CLEAR ON TUESDAY...AND
WEDNESDAY WILL EVEN SEE SOME SLIGHTLY WARMER TEMPERATURES. ON
THURSDAY AND FRIDAY ANOTHER TROUGH WILL DROP DOWN FROM THE NORTH
BRINGING COOLER TEMPERATURES...GUSTY WINDS AND A SLIGHT CHANCE OF
SHOWERS.

&&

.UPDATE (TODAY)...
A LARGE POSITIVE TILT TROUGH IS APPROACHING THE CALIFORNIA COAST
THIS MORNING. ONSHORE FLOW AT THE SURFACE AND ALOFT PRODUCED MARINE
LAYER CLOUDS ACROSS COASTAL AND SOME VALLEY AREAS OVERNIGHT. FOR THE
MOST PART CLOUD BASES WERE HIGH ENOUGH THAT FOG WAS FAIRLY
LIMITED...WITH THE EXCEPTION OF THE SALINAS VALLEY WHERE DENSE FOG
PERSISTED FOR SEVERAL HOURS EARLIER THIS MORNING. THE CLOUD LAYER IS
ALREADY BEGINNING TO BREAK UP OVER THE CENTRAL COAST ZONES THIS
MORNING...AND ACROSS THE SOUTHLAND STRATUS CEILINGS RANGE FROM 2700
TO 3100 FEET NEAR THE COAST WITH SOME 1500 FOOT CEILINGS FURTHER
INLAND. EXPECT THE LOW CLOUDS TO CONTINUE TO SCATTER OUT THROUGH THE
MORNING. AHEAD OF THE APPROACHING TROUGH...MID TO UPPER LEVEL CLOUDS
SHOULD BEGIN TO STREAM ACROSS THE AREA BY LATE MORNING WITH SKIES
BECOMING MOSTLY CLOUDY BY LATE AFTERNOON INTO THIS EVENING.

.FROM PREVIOUS DISCUSSION (TONIGHT-TUE)...
A CUT OFF LOW WILL BEGIN TO FORM AT THE BASE OF THE TROF TONIGHT.
ALL THE MDLS HAVE A SOMEWHAT DIFFERENT TAKE ON WHERE AND WHEN THIS
CUT OFF IS GOING TO OCCUR. THE GFS CUTS IT OFF EARLY AND JUST OFF
THE COAST IT WILL BRING STEADY RAIN TO THE CENTRAL COAST AFTER
MIDNIGHT. THE NAM IS SLOWER AND BRING THE LOW A LITTLE MORE
SOUTHWARD WHICH RESULTS IN NO RAIN FOR THE TONIGHT PERIOD. THE EC IS
THE MOST ROBUST RAIN MDL AND BRINGS RAIN TO ALL AREAS BEFORE DAWN ON
MONDAY. USED CHANCE WORDING FOR THE OVERNIGHT FORECAST WHICH SEEMS A
GOOD COMPROMISE.

ON MONDAY ALL THE MDLS AGREE THAT THE UPPER LOW WILL BE SITTING TO
THE SOUTHWEST OF POINT CONCEPTION. THIS PUTS THE AREA SOUTH OF POINT
CONCEPTION IN A GOOD SW FLOW PATTERN. THE GFS IS VERY AGGRESSIVE
WITH RAIN THE EC LESS SO AND NAM MUCH LESS SO. RAIN SHOULD BE LIKELY
THROUGH THE DAY FOR LA AND VTA COUNTIES AS WELL AS SOUTHERN SBA
COUNTY. IF THE NAM VERIFIES HOWEVER IT WILL JUST BE MOSTLY CLOUDY.
THE CENTRAL COAST MAY ACTUALLY HAVE A BIT OF TROUBLE GETTING ANY
RAIN AND DECREASED POPS THERE TO CHANCE. A GOOD COLD POOL OVER LOW
AS WELL AS DECENT DIFFLUENCE IN THE UPPER LEVEL FLOW AHEAD OF THE
LOW WILL ALLOW FOR A SLIGHT CHC OF A THUNDERSTORM DURING THE
AFTERNOON. 550 HGTS AND LOTS OF CLOUDS WILL KEEP MOST CST AND VLY
MAX TEMPS IN THE MID TO UPPER 50S WITH MAYBE SOME LOWER 60S.

MONDAY NIGHT THE UPPER LOW WILL MOVE EASTWARD INTO SAN DIEGO IT WILL
CONTINUE TO SPIN RAIN INTO THE AREA ESP L.A. COUNTY. AGAIN THERE
WILL NOT BE MUCH CHC OF RAIN FOR THE CENTRAL COAST. THE CHANCE OF
THUNDERSTORMS WILL CONTINUE FOR LA AND VTA COUNTY AND THE SOUTHERN
COASTAL WATERS.

THE LOW MOVES OUT TUESDAY MORNING AND SHOWERS SHOULD DIMINISH. THE
ONLY WORRY IS FOR THE ANTELOPE VLY WHICH WILL SEE DECENT WRAP AROUND
INTO THE VLY FROM THE EAST THIS COULD CAUSE A DECENT SNOW EVENT IN
THE FOOTHILLS.

WINTER STORM WATCH REMAINS IN EFFECT FOR THE MTNS OF L.A. COUNTY AND
IF THE WETTER GFS VERIFIES THERE INDEED WILL BE WINTER STORM
CRITERIA. NOT SO MUCH IF THE NAM VERIFIES. WILL KEEP IT A WATCH FOR
NOW AND SEE WHAT THE MDLS HAVE TO SAY TODAY. THIS WILL BE A COLD
SYSTEM AND SNOW COULD FALL AS LOW AS 3500 FEET BY MONDAY NIGHT. BEST
CHANCE OF MODERATE SNOW WILL OCCUR MONDAY AFTERNOON AND EVENING.
THERE IS A POSSIBILITY OF 8 TO 10 INCHES OF SNOW ABOVE 5000 FEET FOR
THE L.A. MTNS WITH ABOUT HALF AS MUCH FOR THE VTA MTNS.

.LONG TERM (WED-SAT)...

EC AND GFS IN RARE DECENT AGREEMENT THROUGH FRIDAY. BOTH BRING DRIER
NW FLOW TO THE AREA WEDNESDAY ALONG WITH HIGHER HGTS. LOOK FOR A
LITTLE MORE SUNSHINE AND SLIGHTLY WARMER TEMPS.

ANOTHER INSIDE SLIDER IS FORECAST TO MAKE ITS WAY DOWN THE CA NV
BORDER OR THURSDAY. BOTH MDLS BRING THIS SYSTEM FAR ENOUGH WESTWARD
TO ALLOW FOR A SLIGHT CHANCE OF RAIN LATER IN THE AFTERNOON AND
OVERNIGHT. ANY WARMING THAT OCCURRED WEDNESDAY WILL BE GONE THURSDAY.

AN UPPER LOW IS FORECAST TO SIT AND SPIN OVER NEEDLES ON FRIDAY.
THIS IS GOOD FOR A SLIGHT CHC OF RAIN ALTHOUGH IT MIGHT ALSO PRODUCE
A DECENT NORTH WIND EVENT IF THE SFC PRESSURE AND COLD AIR ADVECTION
LINES UP RIGHT.

ON SATURDAY THE EC KEEP THE UPPER LOW NEAR BY WHILE THE GFS MOVES IT
OUT AND MOVES A RIDGE IN. KEPT THE FORECAST DRY AND COOL WITH A FEW
CLOUDS.

&&

.AVIATION...11/1800Z.

MID/UPPER LEVEL TROUGH OF LOW PRESSURE UPSTREAM WILL MOVE OVER THE
AREA. UPPER LEVEL STRONG SOUTHWEST WINDS WILL BECOME MODERATE WHILE
MID LEVEL MODERATE SOUTHWEST WINDS PREVAIL OVER THE AREA. MOISTURE

FRONT IS EXPECTED TO DEVELOP WEST OF THE CHANNEL ISLANDS TONIGHT AND
MOVE ASHORE MONDAY. ISOLATED THUNDERSTORMS ARE EXPECTED TO DEVELOP
IN THE VICINITY OF THE FRONT AND MOVE NORTHEAST 15-20KT WITH TOPS
APPROXIMATELY 35KFT. LOW LEVEL CLOUD TOPS WERE APPROXIMATELY 3.3KFT
THIS MORNING AND WILL ASCEND AND MERGE WITH APPROACHING FRONT
TONIGHT. FREEZING LEVEL WAS AROUND 8.5KFT THIS MORNING AND WILL
DIFFER BY MINUS 3KFT AFTER 12/06Z.
