SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1005 PM PDT SAT JUL 26 2008

.SHORT TERM (TONIGHT-TUE)...MARINE LAYER HAS INCREASED TO NEAR 1500
FT DEEP THIS EVENING AT LAX. LOW CLOUDS MUCH MORE EXTENSIVE OVER THE
SOCAL BIGHT TO THE COAST THIS EVENING THAN 24 HOURS AGO. IT LOOKS
LIKE ALL COASTAL SECTIONS S OF PT CONCEPTION SHOULD HAVE PLENTY OF
LOW CLOUD COVERAGE OVERNIGHT AS THE LOW CLOUD FIELD CONTINUES TO
EXPAND. SOME OF THE ADJACENT VALLEYS WILL HAVE LOW CLOUDS AND FOG
DEVELOPING OVERNIGHT AS WELL. ALONG THE CENTRAL COAST...A S SURGE OF
LOW CLOUDS OFF THE COAST WILL SPREAD E AND INTO THE CENTRAL COAST
LATER TONIGHT AS WELL. ELSEWHERE...MOSTLY CLEAR SKIES WILL PREVAIL
OVERNIGHT.

A VERY WEAK UPPER TROF WILL MOVE INTO SWRN CA LATER TONIGHT AND SUN.
UPPER RIDGING SHOULD THEN BUILD BACK INTO THE REGION FOR MON THRU
TUE. SOME MID LEVEL MOISTURE WILL LINGER OVER THE AREA ON SUN...BUT
WITH MARGINAL INSTABILITY EXPECTED...JUST A FEW AFTERNOON CU
BUILDUPS SHOULD OCCUR OVER THE L.A./VTU MTNS. OTHERWISE...THE MARINE
LAYER SHOULD CONTINUE TO AFFECT COASTAL AND SOME VALLEY AREAS THRU
THE PERIOD WITH VARYING AMOUNTS OF NIGHT AND MORNING LOW CLOUDS AND
FOG. TEMPS OVER THE DISTRICT WILL BE NEAR NORMAL ALONG THE COAST...
AND GENERALLY NEAR NORMAL INLAND...EXCEPT WARMING TO A FEW DEGREES
ABOVE NORMAL BY TUE.

...FROM PREVIOUS DISCUSSION...

.LONG TERM (WED-SAT)...ECMWF REALLY CAME AROUND TO THE GFS PATTERN
FOR NEXT WEEK SHOWING A TROF MOVING INTO THE PAC NW WHILE HIGH
PRESSURE TRIED TO NUDGE ITS WAY INTO CA FROM THE SOUTHEAST. ALTHOUGH
THIS SHOULD STILL ALLOW FOR A SLIGHT WARMING TREND THROUGH THE END
OF THE WEEK, THE INFLUENCE OF THE TROF TO OUR NORTH SHOULD PREVENT
HIGHS FROM GOING UP TOO MUCH. NEITHER MODEL SHOWS ANY INCREASE IN
MONSOONAL MOISTURE THROUGH NEXT WEEKEND AS SOUTHWEST FLOW ALOFT
SHOULD KEEP ALL THAT TO OUR EAST.

&&

.AVIATION...27/0500Z...GOOD CONFIDENCE IN LOW CLOUDS AND IFR TO MVFR
CIGS FOR THE COAST AND ADJACENT VALLEYS OVERNIGHT INTO SUN. THE LOW
CLOUDS WILL CLEAR BACK TO THE COAST BY AFTERNOON WITH GENERALLY VFR
CONDITIONS EXPECTED...EXCEPT OCCASIONAL MVFR CIGS FOR KLAX AND KOXR
THRU THE AFTERNOON.

KLAX...GOOD CONFIDENCE IN MVFR CIGS THRU SUN MORNING...WITH
OCCASIONAL MVFR CIGS POSSIBLY LINGERING INTO THE AFTERNOON. NO WIND
ISSUES EXPECTED THRU SUN.

KBUR...GOOD CONFIDENCE IFR TO LOW MVFR CIGS WILL MOVE IN OVERNIGHT
THEN PERSIST THRU MUCH OF SUN MORNING...THEN VFR CONDITIONS SHOULD
DEVELOP BY MIDDAY EXPECT MVFR VSBYS CANNOT BE RULED OUT. NO WIND
ISSUES EXPECTED THRU SUN.
