The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Miami, FL wrote its last area forecast discussion before this special weather statement went out at Jun 6, 3:20 AM EDT, 2 hours 11 minutes earlier.
Area forecast discussion, Jun 6, 3:20 AM EDT, 2 hours 11 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 320 AM EDT WED JUN 6 2012 .DISCUSSION...LOOKING AT THE SHORT TERM PERIOD THROUGH FRIDAY THE NAM, GFS AND ECMWF ARE VERY SIMILAR IN THE OVERALL SYNOPTIC PATTERN WITH FCST SOUNDINGS NEARLY IDENTICAL. HAVING STATED THAT, THE NAM STILL SEEMS TO BE SUFFERING FROM ITS TYPICAL MESOSCALE BIAS WITH LOCALIZED HIGHER POPS FROM DAY TO DAY. ONE INTERESTING NOTE TOO IS THAT THE HRRR WHICH IS A NORMALLY VERY USEFUL SHORT TERM MODEL HAS APPEARED TO HAVE INITIALIZED BADLY THIS EVENING AND SHOWS A LARGE FLARE UP OF CONVECTION ALONG THE W CST JUST NORTH OF APF AND THEN EXPAND EASTWARD ACROSS THE LAKE OKEE REGION AFTER MIDNIGHT. EVEN THOUGH THERE DOES SEEM TO BE A VERY WEAK MID LEVEL TROUGH MOVING THROUGH THE EASTERN GOFMEX AT THIS TIME, THIS SCENARIO WOULD APPEAR HIGHLY UNLIKELY GIVEN THE CLIMATOLOGICAL FACTORS OF THAT TYPE OF AN EVENT FOR THIS TIME OF YEAR AND THEREFORE DO NOT PLACE MUCH EMPHASIS ON ITS SOLUTION FOR TODAY. THERE IS A LARGE MID LEVEL TROUGH THAT COVERS THE EASTERN HALF THE COUNTRY AT THIS TIME AND THIS SYSTEM WILL MOVE VERY LITTLE THROUGH FRIDAY. AT THE SFC, A WEAK FRONTAL BOUNDARY CURRENTLY OVER SOUTHERN GEORGIA WILL SLOWLY SAG SOUTH AND CONTINUE TO WEAKEN THROUGH THE END OF THIS WEEK KEEPING A SFC RIDGE ACROSS THE EXTREME SOUTHERN TIP OF THE PENINSULA AND THE FL STRAITS. THESE FEATURES WILL COMBINE TO FAVOR A SOUTHWEST STEERING FLOW AND A CONTINUING DESTABILIZATION OF THE ATMOSPHERE FOR S FL WITH CONVECTION TENDING TO DEVELOP LATE IN THE MORNING ACROSS THE INTERIOR AND MOVE TOWARDS THE E CST METRO REGION IN THE AFTERNOON PARTICULARLY BROWARD AND PALM BEACH COUNTIES. ABOUT THE ONLY DIFFERENCE IN THE MAIN THREE MODELS IS ON FRIDAY WHERE THE 00Z GFS AND THE 12Z ECMWF SHOW THE WEAKENING BOUNDARY NEAR LAKE OKEE BY LATE FRIDAY AND THE NAM KEEPS IT WELL NORTH OF THE LAKE THROUGH THE DAY. GIVE THESE DIFFERENCES, NOT READY TO JUMP ON THE HIGHER POPS FOR FRIDAY SHOWN BY THE ECMWF AND WILL CONTINUE TO KEEP SCT COVERAGE. IN THE EXTENDED PERIOD FOR SATURDAY INTO EARLY NEXT WEEK, THE MODELS INDICATE THE DISSIPATING FRONT WILL BE OVER S FL ON SATURDAY WITH BOTH THE GFS AND ECMWF INDICATING SCT POPS. FOR SUNDAY THROUGH TUESDAY HOWEVER, THE SOLUTIONS ARE NOT QUITE SO APPARENT. BOTH MODELS SHOW A STRONG MID LEVEL TROUGH MOVING INTO THE SOUTHERN MISSISSIPPI VALLEY ON SUNDAY AND THEN THE GFS MOVES THE TROUGH INTO THE NORTH FLORIDA MONDAY AND TUESDAY WHILE THE ECMWF LIFTS THE TROUGH NORTHEAST INTO THE OHIO VALLEY. THIS WOULD TEND TO GIVE S FL A QUITE DIFFERENT WX PATTERN WITH THE GFS PAINTING A WETTER PICTURE AND THE ECMWF SHOWING A DRYING PATTERN. SO WILL CONTINUE TO INDICATE ONLY SCT ACTIVITY UNTIL THERE IS A MORE CONSISTENT SOLUTION TO THE EVOLUTION OF THIS TROUGH. && .MARINE...A LIGHT TO MODERATE SOUTHERLY WIND FLOW WILL CONTINUE THROUGH THE END OF THIS WEEK WITH FAIRLY TRANQUIL SEAS. THERE IS AN INDICATION OF A SHORT FUSED WIND SURGE TONIGHT AS THE GRADIENT FLOW BRIEFLY STRENGTHENS BUT SEAS WILL REMAIN BELOW CRITICAL HEIGHTS. THE FLOW WILL SUBSTANTIALLY WEAKEN TOWARDS THE WEEKEND AS THE WEAKENING FRONTAL BOUNDARY APPROACHES THE REGION. THERE WILL ALSO CONTINUE TO BE AN INCREASING THREAT FOR CONVECTIVE ACTIVITY AS THE WEEKEND APPROACHES. && .FIRE WEATHER...NO PROBLEMS OR CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...
