154 PM EDT MON JUL 16 2012

.DISCUSSION...LATE NIGHT/EARLY MORNING CONVECTION CONTINUED TO
DIMINISH OVER THE WATERS EARLIER WITH DEBRIS CLOUD FIELD ALSO
THINNING. THE MORNING SOUNDING SHOWED A TAD BIT MORE INSTABILITY
SINCE SUNDAY MORNING WITH SLIGHT COOLER MID LEVEL TEMPS AND
SLIGHTLY WARMER LOW LEVEL TEMPS. THIS ALONG WITH PLENTY OF DIURNAL
SFC HEATING WOULD MAKE YOU BELIEVE EARLIER ONSET TO CONVECTION
FROM 24 HOURS AGO. HOWEVER, THIS DID NOT MATERIALIZE WITH
CONVECTION ONCE AGAIN BEING DELAYED THIS AFTERNOON. AFTER SOME
ANALYSIS HAVE DISCOVERED FAIRLY STRONG UPPER LEVEL CONVERGENCE
OCCURRING ACROSS THE REGION BETWEEN THE TUTT LIKE FEATURE
STRETCHING ACROSS NORTH/CENTRAL FL AND A STRONG RIDGE NORTH OF
HISPANIOLA AND THE BAHAMAS. SO ADJUSTED THE AFTERNOON POPS ONLY
SLIGHTLY AND DELAYED THE REAL ACTION FOR LATE THIS AFTERNOON.

AT ANY RATE, THESE TWO SYNOPTIC FEATURES WILL CONTINUE TO SHIFT WEST
OVER THE NEXT 24 TO 48 HOURS WITH SIGNIFICANT SUBSIDENCE BEGINNING
TO OCCUR  BY LATE WEDNESDAY AND IN EARNEST ON THURSDAY. THUS, THE
LOWERING TREND OF POPS CURRENTLY BEING ADVERTISED IN THE LOCAL FCST
WILL CONTINUE. IN FACT, THE FCST SOUNDINGS SHOW PWAT'S DROPPING TO
AROUND 1.25 INCHES ON THURSDAY WHICH WOULD RUN BELOW THE 25TH
PERCENTILE. THOSE LOW PWAT VALUES COMBINED WITH RISING 50H WILL
LOWER THE AMOUNT OF CLOUD COVER AND ALLOW FOR CLIMBING AFTERNOON
TEMPS WELL INTO THE 90S ESPECIALLY INTERIOR AREAS. THUS, HEAT
INDICES WILL LIKELY BE IN THE RANGE OF 100-105 ALONG BOTH COASTS AND
105-109 OVER THE INTERIOR FOR BOTH WEDNESDAY AND THURSDAY. IN
ADDITION, AN AREA OF AFRICAN SAHARAN DUST IS BEING TRACKED WITH
SATELLITE IMAGES OVER THE ATLANTIC WITH THIS LIKELY MOVING OVER S FL
POSSIBLY AS EARLY AS TUESDAY AFTERNOON BUT MORE PROBABILISTIC FOR
WEDNESDAY AND THURSDAY MAKING FOR A HAZY SKY. DEEPER LAYER
MOISTURE WILL ONCE AGAIN BE ON THE INCREASE TOWARDS THE WEEKEND SO
HIGHER CHANCES FOR RAIN WILL RETURN.
