Area forecast discussion, Jul 16, 1:54 PM EDT, 2 hours 16 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 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. && .MARINE...MOSTLY AN EAST TO SOUTHEAST WIND OF LESS THAN 15 KNOTS THROUGH THE PERIOD WITH SEAS AT 4 FT OR LESS. && .FIRE WEATHER...NO PROBLEMS OR CONCERNS WITH LOW LEVEL MOISTURE REMAINING HIGH. && .PRELIMINARY POINT TEMPS/POPS...
