NWS Miami, FL wrote its last area forecast discussion before the first event at Aug 11, 1:00 AM EST, 7 hours 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 200 AM EDT SAT AUG 11 2001 NOT MUCH CHANGE TO MAKE TO CURRENT FORECAST. BIGGEST THING ON 00Z MFL SOUNDING IS THE OVERALL LACK OF STEERING FLOW (WHICH WE HAVE ALLUDED TO FOR THE PAST SEVERAL DISCUSSIONS) AND IT LOOKS AS THOUGH THIS WILL CONTINUE TO BE THE CASE FOR THE NEXT 24 TO 48 HOURS. SO WITH SEA BREEZES AGAIN EXPECTED ALONG BOTH COASTS... AND LOCAL BOUNDARIES FROM CONVECTION WHICH WILL DEVELOP FROM AFTERNOON HEATING AND THE SEA BREEZES... LOOKS LIKE CELLS COULD DRIFT SLOWLY IN ANY DIRECTION... AND POPS WILL BE FAIRLY UNIFORM. THE EXCEPTION WILL BE THE INTERIOR WHERE THE SEA BREEZE COLLISION WILL TAKE PLACE... AND WHERE THE LAKE BREEZE COULD ENTER THE MIX. MAY WORD THE METRO FORECAST TO EMPHASIZE THE WESTERN SUBURBS FOR CONVETION. THE IMMEDIATE BEACHES SHOULD BE THE DRIEST SPOTS. MARINE-WISE LIGHT WIND FLOW WITH COASTAL SEA BREEZES. BY EARLY NEXT WEEK MORE OF A EASTERLY GRADIENT SHOULD DEVELOP WHICH COULD CUT DOWN ON ANY WEST COAST SEA BREEZE ACTION THEN. EXTENDED-WISE NOTHING LOOKS CHANGED... FLOW STILL LOOKS LIGHT SO MAINLY AFTERNOON AND EVENING CONVECTION WILL CONTINUE ON THROUGH THE EXTENDED PERIOD. PBI BB 091/076 090/077 090 4242 FLL BB 091/078 090/079 090 4242 MIA BB 091/078 090/078 090 4242 APF BB 090/074 090/075 091 4243 .MIA...NONE.
