EVENT...MOISTURE PLUME HAS SETTLED OVER ISLAND...CONVECTIVE BOUNDARIES AND
THEIR INTERACTION WILL DICTATE HVY RAIN PERSISTENCE AREAS INTO EVENING...
.
SATELLITE ANALYSIS AND TRENDS...MOISTURE PLUME OR HIGHEST CONCENTRATION
OF LOW TO MID LEVEL MOISTURE RIGHT OVER THE ISLAND AS FRONT WELL TO THE
NORTHEAST PUSHES EAST AND TRAILING END STALLS AND IS MEETING UP WITH DEEP
MOISTURE THAT HAS COME IN FROM THE SOUTHEAST.  MOISTURE WHICH HAPPENS TO
BE ABOUT 120-140 PERCENT OF NORMAL MAY MOVE SOUTHWARD AGAIN...BUT PROBABLY
NOT TOO FAR TO ELIMINATE CONTINUED DAYTIME CONVECTIVE ACTIVITY ON MONDAY.
RIGHT NOW DAYTIME HEATING...MOISTURE AND LITTLE BIT OF CONVERGENCE AND
OROGRAPHIC LIFT ALONG WITH BOUNDARY INTERACTION KEEP ACTIVITY GOING MOSTLY
OVER THE CENTRAL MOUNTAINS.  BUT CELLS AND BOUNDARIES DO DRIFT EAST AND
SE AND INTERACT WITH CONVECTIVE ACTIVITY FORMING OVER THE MOUNTAINS IN
SELY FLOW AND ANY ONE SPOT ENCOUNTERING MULTIPLE HVY RAIN BURSTS CAN
ALLOW THAT AREA TO HAVE A HEIGHTEN FF THREAT.  THIS CENTERED FROM FROM
LAS MARIAS IN THE WEST TO BARRANQUITAS IN THE CENTRAL TO RIO GRANDE
IN THE NORTHEAST.  LOWS ROTATING AROUND EACH OTHER 60-50W NORTH OF 35N
PROBABLY WON'T DISSIPATE THE MOISTURE AND FRONT OVER THE AREA. SHORT WAVE
TO THE NORTHWEST COULD SLIDE FAR ENOUGH EAST TO BRING A LITTLE DRIER AIR
IN MONDAY...BUT RIGHT NOW CAN HAVE THE EFFECT OF DESTABILIZING WEAKLY
THE ATMOSPHERE THRU THE EVENING HOURS.  WILL CONTINUE TO MONITOR...BUT
WITH SUCH WARM TOPS...PERSISTENT CELLS AND BOUNDARY MERGERS WILL BE
MAIN DRIVING FACTORS FOR RAINFALL TO RESULT IN ISOLATED URBAN TYPE FF
THRU EVENING.
