NWS Miami, FL wrote its last area forecast discussion before the first event at Sep 23, 8:55 AM EST, 2 hours 45 minutes earlier.
SOUTH FLORIDA AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 955 AM EDT TUE SEP 23 2003 WINDS CURRENTLY VERY LIGHT OR CALM ACROSS SOUTH FLORIDA WITH SURFACE RIDGE PARKED OVER THE REGION. MORNING SOUNDING AT KMFL INDICATES AIRMASS REMAINS DRY...BUT A BIT MORE UNSTABLE THAN IT WAS ON MONDAY. WITH LIGHT NORTHERLY STEERING FLOW IN PLACE EXPECT ANY CONVECTION TO DEVELOP ALONG SEABREEZES AND DRIFT SLOWLY SOUTH. CURRENT FORECASTS HANDLING SITUATION WELL. NO UPDATES REQUIRED AT THIS TIME. PREVIOUS DISCUSSION................................................. .DISCUSSION...IT WOULD APPEAR THAT WE WILL BE SET UP FOR THE FOLLOWING PATTERN THROUGH THE WEEK. A NORTHEAST/SOUTHWEST UPPER RIDGE OVER THE WESTERN ATLANTIC. A BROAD UPPER TROUGH OVER THE EASTERN U.S. AND INTO THE NORTHERN GULF OF MEXICO WITH ANOTHER UPPER RIDGE OVER THE WESTERN U.S. AND EASTERN PACIFIC. THE COOL FRONTAL TROUGH HAS MOVED INTO NORTHERN FLORIDA EARLY THIS MORNING. AS ITS UPPER SUPPORT IS MOVING RAPIDLY NORTHEAST, IT SHOULD STALL OVER THE NORTHERN PENINSULA AS THE ATLANTIC RIDGE KEEPS SUCH FEATURES FROM MOVING TOO FAR TO THE SOUTH. THE ATLANTIC SURFACE RIDGE DID MOVE EAST AHEAD OF THIS FRONTAL TROUGH, AND IT SHOULD BEGIN TO BUILD BACK ON THURSDAY. THE UPPER LOW OVER THE ATLANTIC NEAR PUERTO RICO AND HISPANIOLA NOW APPEARS TO BE ABOUT CUTOFF SO IT SHOULD HAVE LITTLE IMPACT ON OUR WEATHER. THE UPPER TROUGH OVER THE EASTERN U.S. WILL KEEP SOME WEAK SURFACE TROUGH OVER THE GULF OF MEXICO THAT WILL EXTEND EAST INTO THE FRONTAL TROUGH OVER NORTHERN FLORIDA THROUGH THE WEEK. THIS TROUGH HAS ALREADY STARTED TO DRAW MOISTURE TOWARD IT AND THIS CAN BE SEEN ON THE GOES SOUNDER DATA ALTHOUGH IT HAS YET TO SHOW UP IN THE GPS PW OR THE RAOBS. SO WILL START TO INCREASE THE PROBABILITIES TODAY AND THEN BRING THEM BACK TO AT OR ABOVE CLIMATE ON WEDNESDAY AND THROUGH THE WEEKEND. SINCE THE SURFACE RIDGE WILL PROBABLY NOT BE BACK STRONG ENOUGH TO DEVELOP AN EASTERLY FLOW PATTERN WILL GO WITH AFTERNOON AND EVENING CONVECTION THROUGHOUT THE ZONES. WILL LEAVE THIS AS THE FORECAST UNTIL WE HAVE A BETTER INDICATION THAT THE OLD FRONTAL TROUGH WILL BE ABLE TO MOVE SOUTH INTO OUR ZONES. .MARINE...WITH NO STRONG RIDGE OR FRONT THE WINDS AND SEAS SHOULD BE GOOD FOR BOATING ALL WEEK. HOWEVER THE CONVECTION WILL BE THE BOATERS PROBLEM. .FIRE WEATHER...NO HIGHLIGHTS. .PRELIMINARY POINT TEMPS/POPS...
