SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
220 PM PDT FRI APR 6 2012

.SYNOPSIS...
HIGH PRESSURE WILL PROVIDE FAIR AND WARMER CONDITIONS TO THE AREA
TODAY INTO EARLY NEXT WEEK. A COUPLE OF LOW PRESSURE AREAS ARE
EXPECTED TO GIVE THE REGION A CHANCE OF PRECIPITATION AND COOLER
TEMEPRATURES BY THE MIDDLE OF NEXT WEEK.

&&

.SHORT TERM (TODAY-MON)...VERY QUIET WEATHER THROUGH EARLY NEXT
WEEK. OFFSHORE GRADIENTS WILL PEAK SATURDAY MORNING BUT UPPER
SUPPORT IS WEAKER THAN TODAY SO NO WIND ADVISORIES EXPECTED BUT
THERE COULD BE SOME ISOLATED GUSTS TO AROUND 40 IN THE FAVORED
MOUNTAIN AREAS AND AROUND 30 IN THE LA/VENTURA VALLEYS. OVERNIGHT
TONIGHT THE DRY AIR AND WEAKER WINDS SHOULD PERMIT TEMPS TO DROP
WELL BELOW FREEZING ACROSS SOME OF THE INTERIOR AREAS SUCH AS
INTERIOR SLO COUNTY AND THE ANTELOPE VALLEY. FOR THESE AREAS A
FREEZE WARNING WILL BE ISSUED. NOT QUITE AS COLD IN THE CUYAMA
VALLEY BUT ENOUGH FOR A FROST ADVISORY. COULD ALSO BE SOME PATCHY
FROST ACROSS PORTIONS OF THE CENTRAL COAST TONIGHT BUT TEMPS SHOULD
STAY ABOVE FREEZING FOR THE MOST PART.

THE WARMING TREND STARTED TODAY AND WILL REALLY KICK IN SATURDAY
WITH MANY 80+ DEGREE READINGS EXPECTED IN THE LA/VENTURA VALLEYS.
MOST COASTAL AREAS WILL BE IN THE 70S EXCEPT FOR THE IMMEDIATE
BEACHES AND THE CENTRAL COAST.

OFFSHORE FLOW WILL WEAKEN SATURDAY NIGHT AND SUNDAY AND ALLOW FOR AN
EARLIER START TO THE SEA BREEZE. SO AS IS TYPICAL WITH WANING
OFFSHORE FLOW EVENTS THE COOLING TREND SUNDAY WILL BE MOST NOTICABLE
AT THE COAST AND MUCH LESS SO ACROSS THE VALLEYS WHERE THERE SHOULD
STILL BE PLENTY OF 80S. MEANWHILE, THE MTNS AND ANTELOPE VALLEY WILL
BE WARMER. FURTHER VALLEY AND COAST COOLING MONDAY WITH THE START OF
A MARINE LYR OVER THE COASTAL WATERS BY AFTERNOON.

.LONG TERM (TUE-FRI)...BIG PATTERN CHANGE STARTING TUESDAY WITH ALL
MODELS IN GENERAL AGREEMENT THROUGH THE END OF THE WORK WEEK. THE
RIDGE ALONG THE WEST COAST WILL SHIFT EAST AND ALLOW THE FIRST
SYSTEM TO PUSH ONSHORE BY TUESDAY NIGHT. GIVEN THE GOOD RUN TO RUN
AND MODEL TO MODEL CONSISTENCY HAVE GONE WITH LIKELY POPS TUESDAY
NIGHT WITH DECEASING POPS GOING INTO WEDNESDAY. PRETTY DECENT PWATS
WITH THIS AND THE TROF IS SOMEWHAT NEGATIVELY TILTED. THERE IS THE
POTENTIAL FOR SOME SLOWING OF THE SYSTEM SO TIMING MAY ULTIMATELY
NEED SOME ADJUSTMENT, BUT GOOD CONFIDENCE THAT THIS SYSTEM WILL
BRING RAIN TO THE AREA TUESDAY NIGHT AND/OR WEDNESDAY.

GENERALLY DRY CONDITIONS THEN EXPECTED WEDNESDAY NIGHT INTO THURSDAY
BUT THEN THE NEXT SYSTEM POISED TO ARRIVE LATE THURSDAY INTO FRIDAY.
BOTH THE GFS AND ECMWF ARE STRONGER AND WETTER WITH THIS ONE AND
TIMING IS AMAZINGLY SIMILAR DESPITE STILL BEING A WEEK AWAY. HAVE
AGAIN GONE LIKELY FOR FRIDAY IN MOST AREAS GIVEN THE CONFIDENCE AND
MODEL CONSISTENCY.

&&

.AVIATION...06/1800Z.
VFR CONDITIONS EXPECTED UNDER CLEAR SKIES AT ALL AIRFIELDS THROUGH
THE FORECAST PERIOD. MAIN CONCERN WILL BE GUSTY W-NORTHWEST WINDS
FOR COASTAL SITES...AND N-NORTHEAST WINDS OVER VALLEYS SITES WITH
ASSOCIATED LOW LEVEL WIND SHEAR AND TURBULENCE. WINDS ARE EXPECTED
TO EASE FROM 03Z-04Z THIS EVENING.

KLAX...GOOD CONFIDENCE IN VFR CONDITIONS FOR THE 18Z TAF.

KBUR...GOOD CONFIDENCE IN VFR CONDITIONS FOR THE 18Z TAF.
