NWS Miami, FL wrote its last area forecast discussion before the first event at Jul 12, 12:50 AM EST, 5 hours 27 minutes earlier.
SOUTH FLORIDA AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI 150 AM EDT SAT JUL 12 2003 THE BASIC POSITION OF THE SURFACE RIDGE IN THE ATLANTIC AND OVER FLORIDA DOES NOT LOOK LIKE IT WILL CHANGE MUCH THROUGHOUT THE FORECAST PERIOD. SO THAT MEANS IT WILL REMAIN NORTH OF OUR ZONES AND WE WILL REMAIN IN EAST/SOUTHEASTERLY FLOW. AT LEAST THROUGH TOMORROW THE RIDGE SHOULD BE SLIGHTLY WEAKER AND THIS SHOULD ALLOW A WEST COAST SEA BREEZE TO DEVELOP BOTH DAYS. AS A RESULT WE SHOULD BE ABLE TO REPEAT THE AFTERNOON AND EVENING THUNDERSTORMS IN THE WESTERN ZONES BOTH DAYS WITH A SCATTERED COVERAGE. BEYOND THAT POINT WE ARE LOOKING AT TROPICAL WAVE TO COME INTO THE AREA BY TUESDAY. THIS SHOULD INCREASE THE PROBABILITIES THROUGHOUT OUR ZONES BY THAT TIME. IN THE MEANTIME AS WE TRANSITION FROM RELATIVELY DRY AIR OVER US TODAY TO MOIST BY MONDAY NIGHT WE WILL SEE JUST A SLOW INCREASE IN COVERAGE. THE BEST CHANCE ON THE EAST COAST WILL BE FOR THE NIGHT/MORNING SHOWERS. AS FOR THE UPPER LEVELS THE UPPER TROUGH OVER THE PENINSULA SHOULD MOVE NORTHEAST TODAY AND THEN WE SHOULD REMAIN UNDER A SLOWLY ERODING UPPER TROUGH THE REMAINDER OF THE WEEK. WITH NO REAL DRYING EXPECTED AFTER THIS NEXT TROPICAL WAVE WILL KEEP A STEADY NEAR CLIMATE RAINFALL PROBABILITY THROUGH THE REMAINDER OF NEXT WEEK. IN THE MARINE WE SHOULD SEE SOME INCREASE IN THE WINDS WITH THE APPROACH OF THE TROPICAL WAVE ON TUESDAY OTHERWISE THEY SHOULD FALL INTO A BASIC EAST/SOUTHEAST FLOW OF 15 KNOTS OR LESS. NO FIRE DANGER HIGHLIGHTS ANTICIPATED. PBI BB 090/080 090/078 089 2222 FLL BB 089/080 088/079 088 2222 MIA BB 090/079 089/078 089 2222 APF BB 091/075 089/075 090 3142 .MIA...NONE.
