SOUTH FLORIDA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI
245 PM EDT THU SEP 4 2003
SHOWERS AND THUNDERSTORMS WERE DEVELOPING ALONG THE WEST COAST AND
EAST COAST SEA BREEZES EARLY THIS AFTERNOON. THE SHOWERS AND
THUNDERSTORMS SHOULD CONTINUE ALONG BOTH SEA BREEZE. BUT THE EAST
COAST SEA BREEZE SHOULD REMAIN CLOSE TO THE COAST WHILE THE WEST
COAST SEA BREEZE MOVES INLAND...AS THE STEERING FLOW IS OUT OF THE
SOUTHWEST.
THE SHOWERS AND THUNDERSTORMS SHOULD END THIS EVENING AS THE HEATING
OF THE DAY IS LOST...BUT THERE COULD BE SHOWERS AND THUNDERSTORMS
DEVELOPING LATE TONIGHT INTO FRIDAY MORNING OVER THE WESTERN AND
NORTHERN REGIONS OF CWA...AS DEPRESSION 12 MOVES SLOWLY TO THE EAST
NORTHEAST TOWARDS THE BIG BEND OF FLORIDA.
THE DEPRESSION IS FORECAST BY NHC TO MOVE OVER NORTHERN FLORIDA ON
SATURDAY. A TROUGH OF LOW PRESSURE EXTENDING SOUTHWEST FROM THE
DEPRESSION WILL MOVE THROUGH SOUTH FLORIDA ON SATURDAY...AND BRING
SHOWERS AND THUNDERSTORMS TO THE CWA FRIDAY AFTERNOON AND FRIDAY
NIGHT. QPF FROM HPC IS CALLING FOR 1 TO 3 INCHES OF RAINFALL OVER
SOUTHERN PART OF THE CWA THROUGH SATURDAY AND UP TO 3 TO 5 INCHES
OVER THE NORTHERN INTERIOR REGION. SO I AM GOING TO PUT UP A FLOOD
WATCH OVER THE HENDRY AND GLADES COUNTIES STARTING FRIDAY 8 AM
THROUGH 8 AM SATURDAY MORNING.
SATURDAY SHOULD BE A LITTLE BETTER AS THE TROUGH OF LOW
PRESSURE WILL BE EAST OF CWA...BUT THERE COULD STILL BE SOME SHOWERS
AND THUNDERSTORMS OVER THE CWA ESPECIALLY ALONG THE EAST COAST AS
THE STEERING FLOW WILL BE OUT OF THE SOUTHWEST.
.EXTENDED FORECAST...
ONCE THE DEPRESSION MOVES INTO THE ATLANTIC WATERS BY SUNDAY...THE
STEERING FLOW SHOULD BECOME NORTHERLY AND ALLOW DRIER AIR TO WORK
INTO SOUTH FLORIDA FROM THE NORTH FOR THE END OF THE WEEKEND AND
EARLY NEXT WEEK. THERE COULD STILL BE A FEW SHOWERS AND
THUNDERSTORMS MAINLY IN THE AFTERNOONS OVER THE CWA DUE TO THE
HEATING OF THE DAY.
BY MID WEEK...THE RIDGE OF HIGH PRESSURE WILL BUILD BACK INTO
FLORIDA FROM THE ATLANTIC...AS THE TROUGH OF LOW PRESSURE OVER THE
PLAIN STATES LIFTS OUT. THIS WILL ALLOW FOR SOUTH FLORIDA TO GET
BACK INTO A MORE SUMMER TIME PATTERN FOR THIS TIME OF YEAR.
.MARINE...
THE WINDS OVER THE ATLANTIC WATERS TONIGHT WILL BE OUT OF THE SOUTH
AT 5 TO 10 KNOTS...THEN INCREASING TO 10 TO 15 KNOTS OUT OF THE

SOUTHWEST ON SATURDAY BEFORE SHIFTING TO THE WEST ON SUNDAY AT 10 TO
15 KNOTS. THE SEAS SHOULD INCREASE FROM 1 TO 2 FEET TONIGHT UP TO 2
TO 4 FEET THIS WEEKEND. THERE COULD ALSO BE SOME SWELLS UP TO 5
FEET IN PALM BEACH WATERS FRIDAY NIGHT AND SATURDAY DUE TO THE
COMBINATION OF FABIAN MOVING NORTHWARD WELL EAST OF SOUTH FLORIDA

THE SOUTH THEN INCREASING TO 15 KNOTS BY FRIDAY NIGHT OUT OF THE
