Area forecast discussion, Jun 14, 2:34 PM EDT, 46 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 234 PM EDT SUN JUN 14 2009 .DISCUSSION...ACTIVITY HAS BEEN SLOW TO DEVELOP TODAY...WITH A FEW SHOWERS POPPING THEN DIMINISHING QUICKLY. HOWEVER...TEMPS HAVE SOARED INTO THE MID 90S PORTIONS OF THE EAST COAST...WITH MIA REACHING 94 (JUST SHORT OF THE RECORD OF 96 SET IN 1998). A NICE CU FIELD IS SEEN ALONG THE INLAND MOVING ATLANTIC SEA BREEZE...AND WITH HOT TEMPS...IT SEEMS ITS JUST A MATTER OF TIME FOR TSTORM ACTIVITY TO DEVELOP IN BOTH COVERAGE AND INTENSITY THROUGH THE REST OF THE AFTERNOON...SO HAVE KEPT WITH HIGH END CHANCE POPS EASTERN AREAS WITH SLIGHT CHANCE POPS ACROSS THE NAPLES AREA. SURFACE RIDGE AXIS WILL REMAIN ACROSS THE SOUTHERN PENINSULA DURING THE EARLY AND MIDDLE PART OF THE UPCOMING WEEK. LOCAL AREA WILL CONTINUE IN A REGION OF LIGHT WIND FLOW WITH MID LEVEL HIGH PRESSURE CENTERED OVER THE GULF AND ANOTHER HIGH CENTERED OVER THE WESTERN ATLANTIC. THIS WILL LEAD TO RATHER LIGHT FLOW THROUGH THE COLUMN. MOISTURE LEVELS AND INSTABILITY WILL SUPPORT THE DEVELOPMENT OF DIURNALLY INDUCED SEA BREEZE CONVECTION EACH DAY. FLOW ABOVE THE SURFACE WILL BE LIGHT WESTERLY...FAVORING CONVECTION EACH AFTERNOON ACROSS THE INTERIOR AND EAST COAST METROPOLITAN AREAS...ESPECIALLY THE WESTERN SUBURBS AS THE SEA BREEZE WILL LIKELY PENETRATE AWAY FROM THE IMMEDIATE ATLANTIC COAST EACH OF THE NEXT SEVERAL DAYS. MADE NO SIGNIFICANT CHANGES TO THE FORECAST WITH POPS RANGING FROM 10-20 PERCENT GULF COAST AND 30-40 PERCENT INTERIOR/ATLANTIC COAST. HAVE KEPT THE TREND OF GOING A DEGREE OR TWO ABOVE GUIDANCE ON MINS AND MAXS...AS IT HAS BEEN WARMER THAN GUIDANCE OF LATE. INTERESTING TO SEE THAT THE MAV/MET GUIDANCE BOTH SHOW THE VISIBILITY DROPPING TO 6SM IN HAZE AT NAPLES ON TUESDAY...BUT NO OTHER LOCAL SITES. COULD ONLY FIND MLB ACROSS CENTRAL FL SHOWING HAZE FOR TUE. THE MODELS ARE HINTING THAT WITH THE FLOW BECOMING MORE ORIENTED DOWN THE PENINSULA...THAT SOME OF THE HAZE OVER THE DEEP SOUTH COULD MOVE INTO THE AREA...MAKING FOR A MILKIER TYPE SKY...BUT THATS ABOUT IT. MADE NO CHANGES TO THE EXTENDED FORECAST AS THERE IS STILL UNCERTAINTY IN WHETHER OR NOT A MID/UPPER TROUGH WILL DIG INTO THE AREA FROM THE NW . THE LATEST GFS HAS COME INTO BETTER LINE WITH THE 00Z ECMWF IN SHOWING MORE RIDGING INTO NEXT WEEKEND. HAVE MADE NO CHANGES TO THE EXTENDED FORECAST WITH CHANCE POPS EACH DAY AND SLIGHT CHANCE EACH EVENING. && .MARINE...LIGHT WIND FLOW WILL PREVAIL THROUGH THE FCST PERIOD AS THE SURFACE RIDGE AXIS REMAINS ALIGNED ACROSS THE AREA...RESULTING IN WINDS GENERALLY 10 KT OR LESS AND SEAS LESS THAN 4 FT. && .FIRE WEATHER...NO CONCERNS AS LOWEST RHS ARE EXPECTED TO BE IN THE 40S INTERIOR EACH DAY. && .PRELIMINARY POINT TEMPS/POPS... WEST PALM BEACH 77 90 76 90 / 10 30 20 40 FORT LAUDERDALE 79 90 79 90 / 10 30 20 40 MIAMI 78 92 78 91 / 10 30 20 40 NAPLES 75 90 76 90 / 10 20 20 20 && .MFL WATCHES/WARNINGS/ADVISORIES... FL...NONE.
