.RAINFALL...

SEPTEMBER SAW A DRIER START WITH LITTLE TO NO PRECIPITATION
OCCURRING OVER THE AREA DURING THE FIRST FEW DAYS. THIS WAS DUE TO
DRIER AIR THAT BUILT INTO THE REGION UNDER A NORTHEAST FLOW PATTERN.
A MEAN NORTHWARD PLACEMENT OF THE ATLANTIC SURFACE RIDGE PROVIDED AN
ONSHORE FLOW THAT KEPT SUFFICIENT MOISTURE TO GENERATE AFTERNOON
SHOWERS AND STORMS MOST DAYS INTO THE REST OF THE MONTH. HOWEVER
CONVECTIVE COVERAGE MUCH OF THE TIME WAS ISOLATED TO SCATTERED AT
BEST WITH OVERALL RAINFALL AMOUNTS AVERAGING AROUND 2 TO 4 INCHES
BELOW NORMAL ACROSS THE REGION. THE MAIN EXCEPTIONS WERE OVER THE
ORLANDO AND VERO BEACH AREAS WHERE LOCALLY HEAVY RAINFALL...
ESPECIALLY BETWEEN THE 5TH AND 7TH...CONTRIBUTED TO PRECIPITATION
TOTALS THAT WERE ABOVE NORMAL FOR SEPTEMBER.
