..HOT AND DRY OCTOBER ACROSS SOUTH FLORIDA
HIGH PRESSURE IN THE MIDDLE AND UPPER LEVELS OF THE ATMOSPHERE
DOMINATED THE WEATHER PATTERN OVER SOUTH FLORIDA DURING THE MONTH OF
OCTOBER. THIS SET THE STAGE FOR A VERY WARM AND DRY MONTH ACROSS
SOUTH FLORIDA. THE ONLY BREAK FROM THIS PERSISTENT PATTERN WAS A
COLD FRONT WHICH SWEPT ACROSS THE AREA ON OCTOBER 17TH, BRINGING
ABOUT THE OFFICIAL END OF THE RAINY SEASON. THE RECORD-BREAKING COOL
WEATHER FOLLOWING THE FRONT ONLY LASTED A FEW DAYS, BEFORE HOTTER
AND MORE HUMID CONDITIONS RETURNED TO THE AREA THROUGH THE END OF
THE MONTH.
AN ALL-TIME HOTTEST OCTOBER RECORD WAS SET IN MIAMI WITH AN AVERAGE
TEMPERATURE OF 82.4 DEGREES FOR THE MONTH OF OCTOBER. THIS WAS 3.6
DEGREES ABOVE AVERAGE, AND BROKE THE PREVIOUS WARMEST OCTOBER RECORD
OF 82.05 DEGREES SET IN 2002. MIAMI OBSERVED 14 DAYS OF TEMPERATURES
REACHING 90 DEGREES OR HIGHER, WHICH TIED THE RECORD FOR MOST NUMBER
OF 90-PLUS DEGREE DAYS SET BACK IN 1989.
MOORE HAVEN RECORDED A TOTAL OF 18 DAYS OF TEMPERATURES REACHING AT
LEAST 90 DEGREES. THIS BROKE THE PREVIOUS RECORD OF 16 DAYS SET IN
1986. LABELLE REGISTERED 22 DAYS OF 90-PLUS DEGREE TEMPERATURES, ONE
