SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
415 AM PDT MON MAR 9 2009

...NEW AVIATION DISCUSSION...

.SHORT TERM...
VERY COOL DAY ON TAP WITH 549DM THKNS OVERHEAD AND A VERY DEEP
MARINE LAYER NEAR 4600 FEET. MAX TEMPS WILL BE ABOUT 8 TO 10 DEGREES
BELOW NORMAL. THE EDDY HAS TAKEN ON A MORE DISORGANIZED APPEARANCE
OVER THE PAST FEW HOURS SURFACE WINDS AT LGB ARE CALM INDICATING
THAT THE EDDY HAS WEAKENED. WITHOUT A STRONG EDDY PROVIDING LIFT THE
CHANCE OF DRIZZLE OR LIGHT RAIN HAS BEEN DIMINISHED AND NOW THE ONLY
THE FOOTHILLS AND COASTAL SLOPES HAVE ANY REAL CHANCE OF SEEING SOME
PRECIPITATION. KEPT THE PESSIMISTIC MOSTLY CLOUDY WORDING FOR
VENTURA AND L.A. COUNTY TODAY ALTHOUGH THIS IS NOT A SLAM DUNK NOW
AS ACARS SOUNDINGS OUT OF KLAX DO NOT SHOW A VERY STRONG INVERSION
AND AS MENTIONED ABOVE THE EDDY IS NOT AS ROBUST AS IT COULD BE. IT
MIGHT TURN OUT TO BE A REVERSE CLEARING DAY WITH MOSTLY SUNNY TO
PARTLY CLOUDY SKIES AT THE COAST AND MOSTLY CLOUDY SKIES OVER THE
VLYS. DECENT WEST PUSH AND COLD AIR ADVECTION WILL CONSPIRE TO
CREATE ADVISORY LEVEL GUSTS IN THE ANTELOPE VALLEY THIS AFTERNOON
AND EARLY EVENING.

HIGH PRESSURE QUICKLY BUILDS INTO NEVADA THIS EVENING AND SWIFTLY
REVERSES THE ONSHORE FLOW TO OFFSHORE. NOT ENOUGH TO CREATE ANYTHING
BUT LOCAL 15 TO 20 MPH CANYON WINDS. IT WILL LIKELY KEEP THE MARINE
LAYER AT BAY EXCEPT FOR SOME CLOUDS LIKELY IN THE LONG BEACH AREA.

FAIRLY NICE DAY TUESDAY WITH MOSTLY SUNNY SKIES AND SOME WARMING
OVER THE COASTS AND VLYS WITH THE WEAK OFFSHORE FLOW. COASTAL SLO
COUNTY MAY BE THE WARM SPOT WITH THE BEST DOWNSLOPE WINDS.

A VERY WEAK TROF MOVES OVERHEAD WEDNESDAY. IT WILL SERVE TO REVERSE
THE OFFSHORE FLOW WHICH WILL COOL THE COASTAL AND VLY TEMPS. HGTS
ARE STILL NEAR 564DM WHICH WILL TRANSLATE TO ANOTHER DAY OF BELOW
NORMAL TEMPS.

THE ONSHORE PUSH WILL LIKELY CREATE A MARINE LAYER WEDNESDAY NIGHT.
RIGHT NOW HAVE IT IN L.A. COUNTY BUT THERE IS A CHANCE FOR THE
CLOUDS TO MAKE IT INTO VENTURA COUNTY.

THURSDAY WILL CONTINUE COOL AS THE AREA WILL BE IN BETWEEN THE
EXITING TROF AND AN APPROACHING EAST PAC RIDGE. HGTS STILL AROUND
564 DM AND TEMPS WILL BE VERY SIMILAR TO WEDNESDAY. THE MORNING
MARINE LAYER WILL QUICKLY BURN OFF TO REVEAL MOSTLY SUNNY SKIES.

.LONG TERM...

GFS AND EC AGREE THAT FRIDAY WILL LIKELY BE THE NICEST DAY OF THE
NEXT 7 AS THE E PAC RIDGE MOVES OVERHEAD. SKIES SHOULD BE SUNNY AND
MAX TEMPS WILL WARM TO NORMAL OR A DEGREE ABOVE.

AFTER FRIDAY THE MDLS DIVERGE AND BY SUNDAY NIGHT THERE IS NOT MUCH
OF ANY AGREEMENT. SATURDAY WILL BE COOLER THAN FRIDAY BUT THERE IS
MUCH DISAGREEMENT ON THE DIRECTION OF THE LOW LEVEL FLOW AND WHETHER
A MARINE LAYER WILL FORM OR NOT. RIGHT NOW JUST WENT FOR A LITTLE
COOLING BASED ON FALLING HGTS AND A LITTLE BETTER ONSHORE FLOW.

WHILE THE EC AND GFS LOOK NOTHING ALIKE SUNDAY AND THE GFS
ENSEMBLES ARE ALL OVER THE MAP...THERE IS AT LEAST CONSENSUS THAT
THERE IS LITTLE CHC OF RAIN. BROUGHT IN SOME PARTLY CLOUDY SKIES BUT
TOOK THE POPS OUT OF THE FORECAST.

&&

.AVIATION...

09/1115Z

A 4500 TO 5000 FOOT MARINE LAYER MAKE FOR A LOW CONFIDENCE FORECAST
DAY. THERE ARE TWO LAYERS OF CLOUDS ONE AROUND 020 AND ANOTHER
AROUND 040. CLEARING THIS AFTERNOON WILL BE VARIABLE ALTHOUGH THE
COASTAL AREAS WILL HAVE THE BEST CHANCE OF CLEARING.

KLAX...ONLY SO SO CONFIDENCE IN TAF. A FEW SPRINKLES ARE POSSIBLE
THROUGH 18Z. MVFR CIG COULD HOLD ON ONE OR TWO HOURS LATER THAN
FCST. BKN TO SCT TRANSITION COULD OCCUR AS EARLY AS 20Z.

KBUR...GOOD CONFIDENCE OF BKN-OVC SKIES LASTING INTO THE EARLY
EVENING. A 40 PERCENT CHANCE OF AN MVFR CIG THIS MORNING. A FEW
SPRINKLES ARE POSSIBLE THROUGH 18Z.
