SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
850 PM PDT THU JUN 4 2009

.SHORT TERM (TONIGHT-SUN)...CLEAR TO PARTLY CLOUDY SKIES COVERED
L.A./VTU COUNTIES EARLY THIS EVENING...WITH PARTLY TO MOSTLY CLOUDY
CONDITIONS FOR SLO/SBA COUNTIES. AN UPPER LOW CENTERED ABOUT 250
MILES OFF THE COAST OF MONTEREY COUNTY IS EXPECTED TO DRIFT EAST
OVERNIGHT AND REACH THE CENTRAL CA COAST BY MORNING. THE BROAD
CYCLONIC FLOW OVER THE FORECAST AREA WILL COMBINE WITH SOME MOISTURE
AT LOW AND MID LEVELS TO RESULT IN SKIES BECOMING MOSTLY CLOUDY
OVERNIGHT FOR MOST AREAS...ALONG WITH A CHANCE OF SHOWERS AND A
SLIGHT CHANCE OF THUNDERSTORMS OVER SLO/SBA COUNTIES OVERNIGHT...AND
JUST A SLIGHT CHANCE OF A SHOWER OR THUNDERSTORM S OF POINT
CONCEPTION MAINLY LATE TONIGHT. GUSTY SW WINDS OVER 30 MPH IN SOME
PARTS OF THE ANTELOPE VALLEY WILL PERSIST FOR A WHILE OVERNIGHT AS
WELL.

THE UPPER LOW WILL CONTINUE TO MOVE SLOWLY INLAND OVER CENTRAL CA ON
FRI ALTHOUGH IT WILL ALSO ELONGATE WITH ANOTHER UPPER LOW CENTER
FORMING OFF THE CENTRAL COAST. THIS NEW LOW WILL MOVE E AND INLAND
OVER CENTRAL CA LATE FRI NIGHT AND SAT...WITH A BROAD UPPER TROF
LINGERING OVER SRN CA. THIS UPPER TROF SHOULD FINALLY MOVE OUT OF
THE REGION BY EARLY SUN WITH A WEAK W TO WNW FLOW ALOFT. UNSETTLED
CONDITIONS WILL PREVAIL FRI AND FRI NIGHT WITH A CHANCE OF SHOWERS
AND THUNDERSTORMS FOR MOST AREAS...ALTHOUGH IT LOOKS LIKE BY EARLY
SAT THERE WILL JUST BE A SLIGHT CHANCE OF SHOWERS OVER THE REGION.
SOME INSTABILITY SHOULD LINGER OVER SLO/SBA COUNTIES ON SAT...AND A
THUNDERSTORM CANNOT BE COMPLETELY RULED OUT FOR THIS AREA BUT FOR
NOW WILL KEEP CHANCES LESS THAN 15 PERCENT. A SLIGHT CHANCE OF
SHOWERS SHOULD PERSIST ON THE N SLOPES OF VTU/L.A. COUNTIES SAT
NIGHT INTO SUN...OTHERWISE DRY WEATHER IS EXPECTED ACROSS THE
FORECAST AREA. THERE MAY ALSO BE SOME MARINE LAYER CLOUDS MAINLY
ALONG THE COAST LATER SAT NIGHT INTO SUN MORNING AS WELL. TEMPS OVER
THE DISTRICT ARE EXPECTED TO REMAIN A SEVERAL DEGREES BELOW NORMAL
FOR THE MOST PART ALTHOUGH SUN WILL BE THE WARMEST DAY.

..FROM PREVIOUS DISCUSSION...

.LONG TERM (MON-THU)...UPPER LEVEL PATTERN WILL REMAIN STRANGE FOR
JUNE...AS A WEAK BUT LARGE TROUGH BACKBUILDS FROM CA TO WELL OFF THE
COAST...THEN SITS THERE INTO THE MIDDLE OF NEXT WEEK. LOW-MID LEVEL
TEMPS DO IMPROVE SOME OVER OUR AREA AS WE SIT IN BETWEEN THIS
FEATURE AND A WEAK TROUGH OVER THE CENTRAL PART OF THE COUNTRY. THIS
SHOULD ALLOW FOR THE MARINE LAYER TO COME BACK AND KEEP COASTAL AND
VALLEY TEMPS FAIRLY CONSTANT. MTN AND INTERIOR TEMPS WILL WARM ON
THE OTHER HAND...BUT STILL STAY SLIGHTLY BELOW NORMAL. THIS TROUGH
WILL EVENTUALLY MOVE ASHORE...BUT CONFIDENCE IS QUITE LOW AT THIS
POINT ON WHEN IT WILL HAPPEN. ENSEMBLES AND ECMWF VARY FROM TUE
NIGHT TO FRI. WHEN THIS ACTUALLY HAPPENS...WE MAY BE IN STORE FOR
ANOTHER RARE JUNE SHOWER AND THUNDERSTORM...BUT WILL WAIT UNTIL
TOMORROWS ROUND PASSES TO TRY TO PIN THE TAIL ON THIS ONE.

&&

.AVIATION...05/0340Z...MODERATE CONFIDENCE MVFR CIGS WILL MOVE INTO
MUCH OF THE DISTRICT TONIGHT INTO FRI...ALTHOUGH IT MAY WIND UP AS
PERIODS OF MVFR CIGS...AND POSSIBLY EVEN IFR AT TIMES ON FRI FOR THE
SBA S COAST THRU KOXR. THERE WILL BE A CHANCE OF SHOWERS AND A
SLIGHT CHANCE OF THUNDERSTORMS TONIGHT N OF POINT CONCEPTION AND IN
ALL AREAS FOR FRI.

KLAX AND KBUR...MODERATE CONFIDENCE MVFR CIGS WILL MOVE IN LATER
TONIGHT INTO EARLY FRI...THEN PLENTY OF CLOUDS BUT SHOULD BE VFR.
THERE WILL BE A CHANCE OF SHOWERS AND A SLIGHT CHANCE OF
THUNDERSTORMS ON FRI AS WELL.
