EVENT...LOW TOP/WARM SUBTROPICAL MOISTURE LIFTING NORTH...FOLLOWED BY
FRONTAL BAND FOR TONIGHT AND SUN MORNING...
.
SATELLITE ANALYSIS AND TRENDS...SUBTROPICAL LOW/WARM TOP CLOUDS (FLATTER
BUT MORE WIDESPREAD THAN YESTERDAY MORNING) WERE LIFTING NORTH ON CURRENT
GOES IR LOOP WITH LEADING EDGE APPRAOCHING 32.5N/118W TO 34N/122W.
LEAD LOW LEVEL VORT NEAR 33N/122W SHEARING OUT BUT MORE LOW LEVEL VORTS
TO THE SOUTH WILL HELP INSURE THAT SUBTROPICAL MOISTURE KEEPING COMING
NORTH TOWARD S CA.  LATEST AMSU MICROWAVE LOOP ALSO CONFIRMED LEADING
EDGE OF DEEP MOISTURE LIFTING NORTH DRY POCKET ALONG AND JUST OFF S CA
COAST WAS SHRINKING WITH 0.75" PW VALUE MARKING THE LEADING EDGE OF THE
SUBTROPICAL MOISTURE MENTIONED EARLIER.  TIMING WILL BE EVERYTHING FOR
MAXIMUM PRECIP POTENTIAL THIS EVENING THRU TONIGHT AS BIG PICTURE STILL
SHOWING UPPER LOW CONTINUING TO DROP SOUTH AS SATELLITE WINDS SHOWING JET
A BIT FURTHER SOUTH (32.5N)THAN THE LATITUDE OF LOW (33N) ON WESTERN SIDE.
SO DIGGING SOUTH WILL CONTINUE A BIT LONGER UNTIL THOSE JET RELATED WINDS
GET FURTHER AROUND THE BOTTOM OF THE TROUGH BETWEEN 27 AND 31N.  FRONTAL
BAROCLINIC BAND INCHING EAST...BUT EXPECT MORE RAPID EAST PROGRESS WHEN
UPPER LOW BEGINS TO TURN EAST LATER THIS AFTERNOON AND EVENING.  ALSO OF
NOTE IS COOLING TOP NEAR 27.5N/120W.  THIS IS WHERE THE LEADING EDGE
OF THE DEEPER SUBTROPICAL MOISTURE (1.45"  AMSU / 1.5" SSMI) IS LIFTING
NORTH AND SO CRITICAL TO HVY PRECIP FORECAST FOR TONIGHT AND SUN MORNING
WILL HOW MUCH OF THIS DEEPER MOISTURE WILL GET INVOLVED AHEAD OF FRONTAL
BAROCLINIC BOUNDARY.   MANY VARIABLES WITH TIMING OF UPPER LOW...DEPTH
OF TROUGH...SUBTROPICAL MOISTURE COMING NORTH AND THE INTERACTION OR
PARTIAL INTERACTION OF ALL TONIGHT.    WILL CONTINUE TO MONITOR...
