SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
910 PM PDT MON APR 29 2002

UPPER LOW CONTINUES TO SPIN NEAR SAN FRANCISCO. VERY WEAK DYNAMICS
FORECAST TO SWING AROUND THE SOUTHERN SIDE OF THE LOW CROSSING THE
CENTRAL COAST LATE TONIGHT AND THE REST OF THE SOUTHLAND ON TUESDAY. 
00Z MESOETA HINTS AT THE THE BEST CHANCE FOR PRECIP OVER LOCAL AREA...
STILL NOT THAT GOOD...AS TIGHT AND WEAKENING BAND OF OMEGAS IS
FORECAST TO BE OVER LA COUNTY BY 00Z/WED. NOT IMPRESSED WITH
SYSTEM...NEVER HAVE BEEN...AND HAVE WATCHED OVER THE LAST FOUR 
FORECAST SHIFTS/DAYS AS EACH MODEL RUN HAS ADVERTISED A WEAKER 
SCENERIO. 

PREVIOUS SHIFT BACKED OUT OF MOST PRECIPITATION EXCEPT SLIGHT CHANCES
ON TUESDAY...ESPECIALLY OVER MOUNTAINS. WITH SOME MOISTURE IN PLACE
AND INEVITABLE LIFT SWINGING AROUND ASSOCIATED UPPER LOW WILL NOT TAKE
THE LAST STEP AND RIP ALL PRECIPITATION OUT OF FORECAST...AND WILL
LEAVE CURRENT PACKAGE AS IS. COULD BE A SPRINKLE OVER THE NEXT COUPLE
HOURS ALONG CENTRAL COAST AS SMALL BAND OF LOW CLOUDS MOVES
INLAND...APPARENTLY LINKED TO A WEAK BAND OF OMEGAS AS INDICATED ON
THE MESOETA. BAND DOES NOT APPEAR TO BE MARINE LAYER RELATED...RATHER
SYNOPIC IN NATURE...AND THUS WILL LEAVE PARTLY CLOUDY AS FORECAST FOR
CENTRAL COAST OVERNIGHT...HOWEVER VARIABLE CLOUDINESS MAY BE A BETTER
FORECAST.

NO CHANGES NECESSARY TO LATTER PERIODS AS MODELS COONTINUE TO
ADVERTISE ONSHORE FLOW WITH A BAGGY RELATIVELY DRY TROF OVER WESTERN
U.S.

LAX 0000. MCCLUNG

.LOX...NONE.
