NWS Miami, FL wrote its last area forecast discussion before the first event at Jun 27, 8:59 AM EST, 37 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 959 AM EDT SAT JUN 27 2015 .UPDATE... SHOWERS DEVELOPING ALONG/JUST INLAND OF EAST COAST THIS MORNING AS FORECAST. EXPECT COVERAGE TO INCREASE THIS AFTERNOON WITH GREATEST CONCENTRATION OF CONVECTION ACROSS WESTERN HALF OF EAST COAST METROPOLITAN AREAS. 12Z RAOB ANALYSIS SHOWS WARM MID-LEVEL AIR...WHICH SHOULD SUPPRESS WIDESPREAD CONVECTION AND REDUCE RISK FOR STRONG TSTMS. NO CHANGES NEEDED TO CURRENT FORECAST. && .PREV DISCUSSION... /ISSUED 759 AM EDT SAT JUN 27 2015/ AVIATION... SURFACE WIND WILL BE L/V EARLY BECMG SSW-SW 5-7 KT ALONG THE EAST COAST AFT 14Z AND THEN VEERING TO THE SSE AFT 16-18Z AS A SEA BREEZE CIRCULATION TRIES TO DEVELOP. A SOUTHWEST SEA BREEZE WILL SET UP AROUND 15-16Z. STEERING FLOW TODAY WILL BE SW-NE SO CONVECTION WILL FAVOR INTERIOR AND EAST COAST TERMINALS. THE TIMING AT ANY ONE TERMINAL DIFFICULT WITH THE TYPICAL S FL TYPE CONVECTION SO LEFT VCTS FOR ALL TAFS. HOWEVER, ENOUGH COVERAGE COULD WARRANT A TEMPO GROUP IN FOR AT LEAST SOME OF THE TERMINALS BUT BEST TIMING ACCORDING TO THE SHORT TERM HIGH RESOLUTION MODELS APPEARS TO BE AROUND 18-21Z SO MAY NEED TO ADD THIS IN LATER FORECASTS. KOB PREV DISCUSSION... /ISSUED 346 AM EDT SAT JUN 27 2015/ DISCUSSION... AS THE EASTERN CONUS TROUGH CONTINUES TO DEEPEN TODAY, THE PRESSURE GRADIENT ACROSS SOUTH FLORIDA WILL TIGHTEN A BIT. THUS, WINDS WILL BE SLIGHTLY STRONGER WHILE CONTAINING MORE SOUTHERLY COMPONENT. SURFACE CONVERGENCE DEVELOPS NEAR THE CITIES, AS SOUTHERLY WINDS SET UP ALONG THE EAST COAST, PERHAPS BARELY BACKING OFFSHORE THIS PM, COMBINING WITH SOUTHWESTERLY FLOW ACROSS THE INTERIOR. HOWEVER, SOME MODEL SOUNDINGS ARE INDICATING H7-H5 LAPSE ACTUALLY CLOSE TO OR PERHAPS WEAKER THAN YESTERDAY, RIGHT AROUND 6C/KM. THIS REMAINS ONE OF THE MITIGATING FACTORS AGAINST WIDESPREAD STORM DEVELOPMENT. GUIDANCE WAS TOO WET YESTERDAY ACROSS THE ENTIRE FORECAST AREA. NONETHELESS LIKE YESTERDAY, HIGHER THAN TYPICAL POPS DURING THIS DRY STRETCH ARE VALID THROUGH THE INTERIOR TO THE EAST COAST. SHOWERS AND STORMS DEVELOPING DURING THE MID TO LATE MORNING HOURS MAY RESULT IN DEBRIS CLOUDS, STUNTING DEVELOPMENT DURING THE AFTERNOON IN SOME AREAS. DESPITE THE PALTRY H7-H5 LAPSE RATES, CAN'T RULE OUT A FEW STRONGER STORMS, AND ANY SLOW MOVING OR BACKBUILDING CELLS, POTENTIALLY LOCKED ALONG THE COAST, ARE POSSIBLE OF PRODUCING VERY HEAVY RAINFALL. LIKE THE PAST FEW NIGHTS, SOME SHOWERS WILL BE POSSIBLE NEAR THE EAST COAST AS THE WEAK SEA BREEZE VEERS ONSHORE. SUNDAY'S FORECAST WOULD SEEM TO UNFOLD LIKE TODAY, ALTHOUGH MIDLEVEL TEMPS DO WARM SOMEWHAT, ESPECIALLY ON THE ECMWF AT H85 AND H7. POPS FROM THE ECMWF ARE MUCH SMALLER THAN THE CONSENSUS AND THIS IS LEADING TO LOWER POPS FROM THE MODEL BLENDS. BETTER AGREEMENT IS OBSERVED ON MONDAY WITH HIGHER POPS ACROSS THE INTERIOR, AS THE SOUTHWESTERLY WINDS BACK TO THE SOUTH ACROSS MUCH OF THE PENINSULA. THE SOUTHEASTERN CONUS TROUGH BEGINS TO LIFT NORTH INTO TUESDAY, AND THE FLOW BACKS TO THE EAST AGAIN, PUTTING THE CITIES BACK INTO A DRIER PATTERN. BY THE MIDDLE AND END OF NEXT WEEK, ANOTHER H5 RIDGE CLOSES OFF OVER SOUTH FLORIDA, WITH STORMS FOCUSED THROUGH THE INTERIOR AND WESTERN SECTIONS. MARINE... SOUTH TO SOUTHWESTERLY WINDS CONTINUE THROUGH EARLY NEXT WEEK. WIND SPEEDS WILL GENERALLY BE 12 KNOTS OR LESS DURING THIS PERIOD. GULF AND ATLANTIC SEAS ARE FORECAST TO BE 2 FEET OR LESS. SHOWERS AND THUNDERSTORMS WILL BE MOST NUMEROUS NEAR THE ATLANTIC COAST DURING THE NEXT FEW AFTERNOONS. MORE STORMS WILL BE OBSERVED OVER THE NEARSHORE GULF WATERS AT THE END OF THE FORECAST PERIOD. && .PRELIMINARY POINT TEMPS/POPS...
