SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
900 AM PST MON FEB 12 2001
MOIST BAND STILL OVER VENTURA AND L.A. COUNTIES. LOW LEVEL FLOW
BECOMING MORE AND MORE SOUTHWEST AS UPPER LOW MOVES ON DOWN THE COAST.
MODELS DIVERGE AFTER 24 HOURS WITH AVN MOVING CIRCULATION CENTER
FURTHER NORTH THAN ETA. BUT LOOKING AT THE XSXNS FORECAST SOLUTIONS
ARE QUITE SIMILAR. AVN ACTUALLY IS THE MOST ROBUST WITH PRECIPITATION.
THINGS TO WATCH TODAY ARE LOW CENTER AS IT MOVES DOWN THE
COAST...STRONG VORT LOB ROTATING AROUND UPPER LOW AND LOW LEVEL
MOISTURE FLOW THAT IS WRAPPING CYCLONICALLY INTO SOUTHERN CALIFORNIA.
RIGHT NOW LARGEST MOISTURE SLUG IS AT 31/124 AND AS LOW MOVES DOWN AND
FORCES LOW LEVEL FLOW MORE SOUTH WEST SHOULD TRAIN INTO US VERY NICELY.
SPENES TRAJECTORY INDICATES THAT L.A. WILL BE FOCUS OF THIS SLUG
TONIGHT.
NEW MODELS LIKE 06Z TO 18Z TIME FRAME FOR MAXIMUM RAIN AS UPPER LOW
SITS AND SPINS TO OUR SOUTHWEST. THIS SEEMS REASONABLE BUT MODELS HAVE
NOT GOT 18 TO 36 HOUR FORECAST RIGHT ONCE IN THE LAST 4 DAYS SO
CONFIDENCE IS NOT HIGH ON THIS. THINK SATELITE IS THE BEST WAY TO GO ON
THIS ONE.
WILL ISSUE UPcDATE TO REFLECT NEW THINKING AND CLEAN UP.
