SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
329 AM PDT SAT JUN 4 2011

.SYNOPSIS...
STRONG LOW PRESSURE WELL OFF THE CENTRAL COAST WILL MOVE SLOWLY
EAST...TRACKING JUST NORTH OF THE AREA EARLY MONDAY. ITS ASSOCIATED
FRONT WILL BRING RAIN TO SAN LUIS OBISPO AND SANTA BARBARA COUNTIES
THROUGH SUNDAY...WITH RAIN POSSIBLY SPREADING INTO VENTURA COUNTY
TONIGHT AND SUNDAY. THE FRONTAL SYSTEM WILL DISSIPATE OVER VENTURA
COUNTY...BUT THERE WILL BE A CHANCE OF SHOWERS ACROSS THE ENTIRE
REGION SUNDAY NIGHT AND EARLY MONDAY AS THE UPPER LOW MOVES INTO
CALIFORNIA. DRY AND COOL WEATHER IS EXPECTED FOR MUCH OF NEXT WEEK.

&&

.SHORT TERM (TODAY-MON)...A VERY UNSEASONABLY STRONG AND COLD UPPER
LOW WAS CENTERED NEAR 37N/127 W EARLY THIS MORNING. TO THE EAST OF
IT...A LARGE SWATH OF DEEP MOISTURE WAS AIMED AT THE CENTRAL
COAST...AND THIS MOISTURE PLUME WAS TAPPING INTO A FAIRLY RICH
MOISTURE SOURCE...WITH PRECIPITABLE WATER VALUES NEAR 1.5 INCHES.
RAIN HAS SPREAD INTO FAR NWRN SXNS OF SLO COUNTY EARLY THIS MORNING.
ALL MODELS SHOW THE BAND OF RAIN EDGING SLOWLY EWD TODAY...WITH RAIN
DEVELOPING THIS MORNING ACROSS MOST OF SLO COUNTY AND NWRN SBA
COUNTY...LIKELY REACHING SOUTHEASTERN SANTA BARBARA COUNTY DURING
THE AFTERNOON. WITH DEEP MOISTURE...AND A NICELY DIFFLUENT HEIGHT
PATTER...SOME OF THE RAIN WILL LIKELY BE MODERATE TO HEAVY AT
TIMES...ESPECIALLY ACROSS THE HIGHER TERRAIN ON AND BELOW SOUTH AND
SOUTHWEST FACING SLOPES...WHERE OROGRAPHIC FLOW WILL ASSIST IN THE
LIFTING PROCESS. THE WRF DOES SHOW A PERIOD OF ADVISORY LEVELS WINDS
ACROSS SLO COUNTY AND MUCH OF SANTA BARBARA COUNTY FROM ABOUT MID
MORNING THROUGH MID AFTERNOON. HAVE GONE AHEAD AND ISSUED WIND
ADVISORIES FOR ALL OF SLO AND SBA COUNTIES...WITH THE EXCEPTION OF
THE S CST OF SBA COUNTY. THE 06Z RUN CAME IS SLIGHTLY WEAKER WITH
THE WINDS...AND IF IT IS CORRECT...WINDS MAY NOT QUITE REACH
ADVISORY LEVELS... ESPECIALLY IN THE SANTA YNEZ VALLEY...AND THE
CUYAMA VLY. WITH ALL THE CLDS AND RAIN...TEMPS WILL BE WELL BELOW
NORMAL ACROSS SLO AND SBA COUNTIES TODAY.

ACROSS L.A. AND VTU COUNTIES...SKIES WERE PARTLY CLOUDY...AND THEY
WILL LIKELY STAY THAT WAY ACROSS L.A. COUNTY THROUGH THE DAY.
DESPITE SOME SUNSHINE...THERE WILL STILL LIKELY BE SOME COOLING EVEN
ACROSS L.A. COUNTY AS ONSHORE GRADS INCREASE. ACROSS VTU COUNTY...IT
DOES APPEAR THAT CLOUDS WILL INCREASE ENOUGH LATER THIS MORNING OR
THIS AFTERNOON TO WARRANT MOSTLY CLOUDY WORDING DURG THE AFTERNOON.
HAVE GONE AHEAD AND ADDED A 20 PERCENT CHANCE OF RAIN ACROSS VTU
COUNTY FOR THIS AFTERNOON...AS SOME LIGHT RAIN COULD SPREAD/DEVELOP
ACROSS THE AREA...ESPECIALLY TOWARD EVENING. GUSTY SOUTH WINDS WILL
DEVELOP ACROSS THE MTNS OF L.A. AND VTU  COUNTIES...WITH GUSTY
SOUTHWEST WINDS IN THE ANTELOPE VALLEY...BUT WINDS WILL PROBABLY
REMAIN BELOW ADVISORY LEVELS IN THESE AREAS.

RAIN WILL CONTINUE ACROSS SLO AND SBA COUNTIES TONIGHT...BUT
PROBABLY BEGIN TO TAPER OFF ACROSS WRN SXNS AS THE AXIS OF THE RAIN
WILL SHIFT TO EASTERN SECTIONS OF THOSE COUNTIES BY LATE TONIGHT..
RAIN WILL PROBABLY SPREAD INTO AT LEAST THE NWRN HALF OF VTU
COUNTIES OVERNIGHT OR EARLY SUNDAY. THERE WILL BE A VERY SHARP
GRADIENT OF RAIN...WHICH WILL INCREASE THE POTENTIAL FOR ERROR...AND
MAKE THE FCST VERY DIFFICULT TO WORD. CASE IN POINT...WHILE RAIN
WILL BECOME LIKELY LATE TONIGHT OR EARLY SUNDAY ACROSS THE WRN MTNS
AND VLYS OF VTU COUNTY AND THE VTU COUNTY COASTAL PLAIN...IT MAY
WELL REMAIN DRY THROUGH SUNDAY MORNING ACROSS ERN VTU COUNTY. IF THE
FRONTAL BAND SETS UP 50 MILES WEST...ALL OF VTU COUNTY WILL REMAIN
DRY. ACROSS L.A. COUNTY...SKIES WILL BE MOSTLY CLOUDY TONIGHT AND
SUNDAY...BUT AT THIS POINT...NO RAIN IS EXPECTED...AS THE FRONT WILL
HANG UP ACROSS VTU AND ERN SBA COUNTIES AND FALL APART AS IT LOSES
SUPPORT FROM ITS SURFACE LOW.

THE UPPER LOW WILL FINALLY BEGIN TO TRANSLATE EWD INTO THE W CST
SUNDAY NIGHT AND EARLY MONDAY...TAKING A TRACK JUST TO THE N OF THE
REGION. THERE WILL BE AT LEAST A SLIGHT CHANCE OF SHOWERS ACROSS THE
ENTIRE REGION ASSOCIATED WITH THE UPPER LOW SUNDAY NIGHT AND MONDAY
MORNING...WITH THE BEST CHANCE ACROSS SLO AND SBA COUNTIES. IF THE
SLOWER WRF IS CORRECT...POPS MAY HAVE TO BE EXTENDED INTO THE
AFTERNOON. THERE COULD BE ENOUGH COLD AIR ALOFT TO ALLOW FOR THE
THREAT OF TSTMS LATE SUN NIGHT/MON NEAR THE CENTER OF THE LOW
ITSELF.

.LONG TERM (TUE-FRI)...THE UPPER LOW WILL ACCELERATE NEWD INTO THE
GREAT BASIN MONDAY NIGHT. ANOTHER SHORT WAVE TROUGH WILL DROP SWD
THRU THE ERN PAC MON NIGHT AND TUE...PUSHING INTO THE CENTRAL COAST
LATE TUE. AT THIS TIME...IT DOES NOT APPEAR THAT THERE WILL BE ANY
RAIN FROM THIS SYSTEM...BUT THE MODELS HAVE BEEN STRONGER AND
FARTHER WEST WITH IT...NOW TAKING IT OVER WATER FOR A WHILE...SO
THAT WILL HAVE TO BE WATCHED. FOR NOW...WILL CONT WITH THE PARTLY
CLOUDY AND COOL FCST FOR TUE. A BROAD TROUGH WILL LINGER ACROSS THE
REGION TUE NIGHT/WED...SO IT WILL REMAIN RATHER COOL. SOME NIGHT
THRU MORNING LOW CLOUDS/FOG WILL LIKELY AFFECT CSTL AND POSSIBLY VLY
AREAS. IT ACTUALLY LOOKS AS THOUGH A BROAD TROUGH WILL NOW LINGER
THROUGH FRI...WHICH WOULD MAINTAIN COOL WEATHER ACROSS THE
REGION...WITH NIGHT THRU MORNING LOW CLOUDS/FOG CONTG IN CSTL AND
VLY AREAS. THERE MAY BE SOME WARMING ACROSS THE INTERIOR VLYS...
AND ESPECIALLY THE MTNS AND DESERTS THU AND FRI AS HEIGHTS SLOWLY
RISE.

&&

.AVIATION...04/1030Z...MODERATE CONFIDENCE WITH 12Z TAF
PACKAGE...EXCEPT LOWER CONFIDENCE IN REGARDS TO SHOWERS S OF POINT
CONCEPTION DUE TO CUTOFF LOW. 40 PERCENT CHANCE OF MVFR/IFR VSBYS
WITH RAIN N OF POINT CONCEPTION. HIGHER CONFIDENCE FOR SHOWERS TO
DEVELOP ACROSS VENTURA COUNTY THROUGH THIS EVENING...WHILE LA COUNTY
REMAINS DRY FOR THE MOST PART. 50 PERCENT CHANCE FOR MVFR/IFR CONDS
WITH SHOWERS. GUSTY SOUTHERLY WINDS ACROSS SLO/SBA.VTU COUNTY
MOUNTAINS THROUGH TODAY. POSSIBLE UDDF OVER PEAKS TODAY.

KLAX...GENERALLY HI CONFIDENCE IN THE CURRENT TAF. MVFR CONDITIONS
WILL PREVAIL THRU 17Z...WITH VFR CONDS AFTER THAT...THEN MVFR CIGS
LIKELY AFT 03Z. NOT MUCH IN PRECIP EXPECTED FOR LA COUNTY THROUGH AT
LEAST SUNDAY.

KBUR...MODERATE CONFIDENCE OVERALL IN THE CURRENT TAF. MVFR CIGS ARE
EXPECTED TO MOVE INTO THE AIRFIELD FROM ABOUT 11Z-16Z BUT THERE IS A
40-50 PERCENT CHANCE THE LOW CIGS MAY NOT AFFECT THE AIRFIELD.
OTHERWISE VFR CONDITIONS SHOULD PREVAIL THRU TODAY.
