...FALL 2011 ENDED UP WITH NEAR NORMAL TEMPERATURES AND NEAR TO
ABOVE NORMAL PRECIPITATION OVER EAST CENTRAL FLORIDA...

SLIGHTLY WARMER THAN NORMAL TEMPERATURES AND DRIER THAN NORMAL
WEATHER CONDITIONS TOWARD BOTH THE BEGINNING AND END OF THE FALL
SEASON (SEPTEMBER/OCTOBER/NOVEMBER) WERE BALANCED OUT BY A COOLER
AND VERY WET WEATHER PATTERN OF OCTOBER OVER THE AREA. THIS LED TO
NEAR NORMAL TEMPERATURES AND PRECIPITATION NEAR TO ABOVE NORMAL
THIS PAST SEASON ACROSS MANY LOCATIONS IN EAST CENTRAL FLORIDA.

.TEMPERATURES...

COLD FRONTS THAT MOVED INTO FLORIDA DURING THE MONTH OF SEPTEMBER
WERE RATHER WEAK WITH TEMPERATURES REMAINING SLIGHTLY WARMER THAN
NORMAL MOST DAYS. HOWEVER A STRONGER COLD FRONT PUSHED SOUTHWARD
THROUGH THE AREA ON THE 1ST OF OCTOBER WHICH BEGAN A COOLER AND
MORE UNSETTLED WEATHER PATTERN THROUGH THE MIDDLE OF THE FALL.
SIGNIFICANT COOLDOWNS ASSOCIATED WITH COLD FRONTAL PASSAGES
CONTINUED INTO NOVEMBER. HOWEVER THE DURATIONS OF BELOW NORMAL
TEMPERATURES THAT FOLLOWED THESE FRONTAL PASSAGES WERE BRIEF AND
QUICKLY MODIFIED BY ONSHORE WINDS THAT DEVELOPED SOON AFTER THE
BOUNDARIES MOVED THROUGH.

SEASONAL AVERAGE TEMPERATURES GENERALLY RANGED WITHIN ONE TO TWO
TENTHS OF A DEGREE FROM NORMAL WITH ORLANDO SLIGHTLY COOLER...BEING
A WHOLE DEGREE BELOW NORMAL FOR THE FALL.

THE AVERAGE TEMPERATURE VALUES FOR FALL 2011 AT THE FOUR MAIN
CLIMATE SITES ACROSS EAST CENTRAL FLORIDA ARE AS FOLLOWS (RANKINGS
PROVIDED IF IN THE TOP 10):

-DAYTONA BEACH HAD AN AVERAGE SEASONAL TEMPERATURE OF 73.2 DEGREES
FAHRENHEIT, WHICH WAS 0.2 DEGREES BELOW NORMAL.

-ORLANDO HAD AN AVERAGE SEASONAL TEMPERATURE OF 74.0 DEGREES
FAHRENHEIT, WHICH WAS 1.0 DEGREE BELOW NORMAL.

-MELBOURNE HAD AN AVERAGE SEASONAL TEMPERATURE OF 75.3 DEGREES
FAHRENHEIT, WHICH WAS 0.1 DEGREES ABOVE NORMAL.

-VERO BEACH HAD AN AVERAGE SEASONAL TEMPERATURE OF 75.9 DEGREES
FAHRENHEIT, WHICH WAS 0.1 DEGREES ABOVE NORMAL.


.RAINFALL...

THE DAILY OCCURRENCE OF ISOLATED TO SCATTERED AFTERNOON SHOWERS AND
THUNDERSTORMS GENERALLY CONTINUED INTO THE BEGINNING OF SEPTEMBER...
FOLLOWED BY PERSISTENT DRIER CONDITIONS LATER IN THE MONTH. A
MORE UNSETTLED WEATHER PATTERN THEN BEGAN ACROSS EAST CENTRAL
FLORIDA INTO OCTOBER WITH A FEW HEAVY RAINFALL EVENTS OCCURRING
ACROSS THE REGION. THE MOST SIGNIFICANT OF THESE TOOK PLACE DURING
THE SECOND WEEKEND OF OCTOBER WHEN STRONG ONSHORE FLOW COMBINED WITH
DEEP MOISTURE TO PRODUCE WIDESPREAD HEAVY RAINFALL OVER EAST CENTRAL
FLORIDA. PRECIPITATION CONTINUED TO BE ENHANCED DURING THIS EVENT AS
A GALE LOW DEVELOPED JUST OFFSHORE OF THE FLORIDA EAST COAST AND
MOVED ONSHORE NEAR CAPE CANAVERAL. MANY AREAS RECEIVED AT LEAST 6 TO
10 INCHES DURING THE PERIOD FROM OCTOBER 7TH TO 9TH WITH LOCALLY
HIGHER RAINFALL AMOUNTS BETWEEN 12 AND 17 INCHES IN SOME LOCATIONS.

THE DRY SEASON BEGAN ON OCTOBER 20TH...DESPITE ONE ADDITIONAL HEAVY
RAIN EVENT IN LATE OCTOBER. RAINFALL THEN BECAME FAIRLY SCARCE INTO
NOVEMBER WITH MOST AREAS RECEIVING LESS THAN ONE INCH OF TOTAL
PRECIPITATION THE ENTIRE MONTH. THE EXCEPTION TO THIS WAS ALONG THE
COAST OF BREVARD COUNTY AND THE TREASURE COAST WHERE MORE FREQUENT
ONSHORE MOVING SHOWER ACTIVITY WAS OBSERVED.

DESPITE DRIER THAN NORMAL CONDITIONS DURING THE BEGINNING AND END
OF FALL...THE CONSIDERABLE RAINFALL THAT FELL IN OCTOBER HELPED MAKE
UP FOR MUCH OF SEPTEMBER AND NOVEMBER'S PRECIPITATION DEFICIT. THE
MOST NOTABLE ASPECT OF THIS RAINFALL WAS THAT VERO BEACH NOT ONLY
HAD THEIR WETTEST OCTOBER ON RECORD...BUT ALSO ENDED UP HAVING THEIR
WETTEST FALL ON RECORD. OBSERVING STATIONS ELSEWHERE ACROSS THE AREA
RECORDED MORE VARIABLE SEASONAL RAINFALL TOTALS THAT WERE WITHIN A
FEW INCHES OF (ABOVE OR BELOW) NORMAL. OVERALL...RADAR DERIVED
PRECIPITATION ESTIMATES SHOW MUCH OF THE AREA EXPERIENCED NEAR TO
ABOVE NORMAL RAINFALL AMOUNTS DURING THE FALL.


FALL 2011 RAINFALL TOTALS FOR THE FOUR MAIN CLIMATE SITES ACROSS
EAST CENTRAL FLORIDA ARE AS FOLLOWS (RANKINGS PROVIDED IF IN THE TOP
10):

-DAYTONA BEACH RECEIVED 12.21 INCHES OF RAINFALL FOR THE SEASON,
WHICH WAS 1.65 INCHES BELOW NORMAL.

-ORLANDO RECEIVED 14.85 INCHES OF RAINFALL FOR THE SEASON, WHICH WAS
3.31 INCHES ABOVE NORMAL.

-MELBOURNE RECEIVED 13.21 INCHES OF RAINFALL FOR THE SEASON, WHICH
WAS 2.37 INCHES BELOW NORMAL.

-VERO BEACH RECEIVED 31.47 INCHES OF RAINFALL FOR THE SEASON, WHICH
