NWS Miami, FL wrote its last area forecast discussion before the first event at Jun 23, 2:43 AM EST, 3 hours 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 343 AM EDT TUE JUN 23 2009 ...HEAT INDICES NEAR 105 ALL AREAS TODAY... ...A FEW STRONG TO SEVERE STORMS POSSIBLE... .DISCUSSION...IT IS A SULTRY MORNING ACROSS SOUTH FL. TEMPS ARE STEADY IN THE LOWER 80S WITH HEAT INDICES STILL IN THE 90S DUE TO VERY HIGH DEWPOINTS IN THE UPPER 70S TO NEAR 80. PRETTY AMAZING THAT THE HEAT INDEX RIGHT NOW AT NAPLES AND FT. LAUDERDALE IS 96. TEMPERATURES TODAY ARE A CHALLENGE AS THE LOCAL AREA WILL STILL REMAIN IN A HOTTER THAN NORMAL AIRMASS. HOWEVER...THE HOT DOME OF HIGH PRESSURE WILL CONTINUE TO MOVE SW AS A TROUGH MOVES IN FROM THE NE. THIS WILL LEAD TO COLD (RELATIVELY SPEAKING OF COURSE) AIR ADVECTION. THIS...ALONG WITH AREAS OF LOW CLOUDS EARLY THIS MORNING...AND THE PROSPECT FOR TSTORM DEVELOPMENT...WILL LEAD ME TO SIDE WITH GFS/NAM GUIDANCE NUMBERS FOR HIGHS THIS AFTERNOON...DESPITE THEIR LOW BIAS OF LATE. HOWEVER...CONVECTION LOOKS LIKELY INTERIOR/EAST COAST...SO WILL GO WITH HIGHS IN THE LOWER 90S AREA WIDE THIS AFTERNOON. I SHOULD SAY THAT IF STORMS HOLD OFF AND PLENTY OF SUN PREVAILS...THEN TEMPS WOULD GO SEVERAL DEGREES HIGHER THAN FORECAST. HEAT INDICES WILL REACH NEAR 105 TODAY...BUT DECIDED NOT TO ISSUE A HEAT ADVISORY DUE TO EXPECTED BORDERLINE CONDITIONS AND THE EXPECTATION OF QUITE A BIT OF SHOWER/TSTORM ACTIVITY WHICH WOULD LEAD TO A QUICK REPRIEVE IN THE HIGH HEAT INDICES. CONDITIONS WILL CONTINUE TO REMAIN VERY UNSTABLE TODAY. CONVECTION OVER THE ATLANTIC OCEAN IS SENDING OUTFLOW BOUNDARIES ONSHORE THE ATLANTIC COAST. THESE BOUNDARIES...AND AN INCOMING SURFACE TROUGH FROM THE NORTH THIS AFTERNOON ALONG WITH SHORTWAVE ENERGY DIVING SOUTH...IS EXPECTED TO LEAD SCT-NUM TSTORMS TODAY...WITH THE FOCUS INTERIOR/EAST COAST. FORECAST SOUNDINGS SHOW HIGH CAPE OF AROUND 4000 J/KG AND LIS AROUND -8C WITH PWATS AOA 2 INCHES. GIVEN THIS...A FEW STORMS COULD BECOME SEVERE WITH DAMAGING WINDS BEING THE PRIMARY RISK. LOCALLY HEAVY RAINFALL WILL ACCOMPANY THE STORMS TODAY AS WELL...BUT THEY WILL BE ON THE MOVE SO WILL JUST HAVE TO KEEP ANY EYE ON WHERE ANY STORMS TRAIN. THE TROUGH AND DEEP MOISTURE LOOKS TO SLOWLY SHIFT SOUTH TONIGHT TO THE FAR SOUTHERN PENINSULA WITH SIGNIFICANT DRYING OCCURRING FROM EAST CENTRAL FL TO THE LAKE OKEECHOBEE-PALM BEACH REGION. HOWEVER...THE MOISTURE LOOKS TO QUICKLY MAKE A COME BACK AS GFS SHOWS A MID LEVEL LOW CLOSING OFF JUST TO OUR WEST. GIVEN THIS...TRENDED POPS DOWN FROM THE LAKE OKEECHOBEE-PALM BEACH REGION FOR WED WITH HIGHEST POPS TO THE SOUTH. KEPT HIGH END CHANCE POPS FOR ALL AREAS FOR THU. TEMPS WILL CONTINUE TO COOL WITH HIGHS EVEN A DEGREE OR TWO BELOW AVERAGE. RATHER HIGH HUMIDITY WILL CONTINUE THOUGH...NO SURPRISE FOR A SOUTH FL SUMMER. GFS SHOWS THE SURFACE ATLANTIC RIDGE OVER THE FL STRAITS FRI...LIFTING NORTH INTO CENTRAL FL SAT BEFORE SHIFTING BACK SOUTH OF THE LOCAL AREA SUN THROUGH THE MIDDLE PART OF NEXT WEEK AS ANOTHER MID LEVEL TROUGH DIVES SOUTHEAST INTO THE WESTERN ATLANTIC. KEPT WITH PREVAILING CHANCE POPS THROUGH THE EXTENDED FORECAST. THE OVERALL PATTERN CONTINUES TO FAVOR A FOCUS OF SHOWERS/STORMS INTERIOR/EAST COAST. NAPLES SURE COULD USE MORE RAIN AS THE RAINFALL DEFICIT THERE IS NEARING A FOOT FOR THE YEAR. && .MARINE...WINDS ARE BLOWING HIGHER THAN GUIDANCE SO INCREASED WINDS FOR THIS MORNING...INTO THE 15-20 KT RANGE FOR BISCAYNE BAY AND THE ATLANTIC WATERS. OTHERWISE...WINDS WILL PEVAIL AT 15 KT OR LESS WITH SEAS 4 FT OR LESS THROUGH THE PERIOD. OF COURSE...STRONGER WINDS AND HIGHER SEAS WILL BE FOUND IN/NEAR STORMS. && .FIRE WEATHER...NO CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...
