...SUMMER 2015 CLIMATE SUMMARY FOR EAST CENTRAL FLORIDA...

THE ATLANTIC HIGH PRESSURE RIDGE REMAINED ACROSS THE REGION IN JUNE
AND COMBINED WITH A STRONG RIDGE ALOFT TO GENERATE ABOVE NORMAL
TEMPERATURES AND DRIER CONDITIONS...ESPECIALLY DURING THE MIDDLE OF
THE MONTH. THEN INTO JULY AND AUGUST THE AVERAGE PLACEMENT OF THE
RIDGE SHIFTED SOUTH OF CENTRAL FLORIDA WHICH LED TO A MORE DOMINANT
OFFSHORE FLOW. THIS HELPED CONTINUE WARMER THAN NORMAL TEMPERATURES
INTO THE SUMMER AND ALSO STEERED MORE SHOWERS AND STORMS TOWARD THE
AREA...INCREASING RAINFALL MID TO LATE IN THE SEASON.


TEMPERATURES...

TEMPERATURES THIS SUMMER STARTED OUT NEAR NORMAL AS THE SEA BREEZE
MOVED STEADILY INLAND EACH AFTERNOON. HOTTER CONDITIONS THEN TOOK
HOLD THROUGH MID JUNE AS A PERSISTENT DEEP HIGH PRESSURE PATTERN
PRODUCED WELL ABOVE NORMAL TEMPERATURES...BREAKING SEVERAL RECORD
HIGHS AND WARM MINIMUM TEMPERATURE RECORDS THROUGH THIS PERIOD.
INTERESTINGLY ON JUNE 19TH ORLANDO REACHED 100 DEGREES FOR THE FIRST
TIME IN 17 YEARS...LAST OCCURRING ON JULY 3RD OF 1998 AT THIS
LOCATION. FROM LATE JUNE INTO THE REST OF THE SUMMER THE AXIS OF THE
ATLANTIC HIGH PRESSURE RIDGE WAS OFTEN SOUTH OF THE AREA. THIS LED
TO A MORE DOMINANT WEST TO SOUTHWEST FLOW THAT REPEATEDLY DELAYED OR
EVEN PREVENTED DEVELOPMENT OF THE EAST COAST SEA BREEZE...CONTINUING
OVERALL WARMER THAN NORMAL CONDITIONS FOR MUCH OF THE SUMMER.

SEASONAL AVERAGE TEMPERATURES RANGED FROM 0.2 DEGREES ABOVE NORMAL
AT MELBOURNE TO 1.5 DEGREES ABOVE NORMAL AT VERO BEACH. ALL PRIMARY
CLIMATE SITES RANKED IN THEIR RESPECTIVE TOP 10 WARMEST SUMMERS ON
RECORD. VERO BEACH WAS THE MOST NOTABLE WITH AN AVERAGE SUMMER
TEMPERATURE OF 82.7 DEGREES FAHRENHEIT...TYING 1998 AS THEIR 2ND
WARMEST SUMMER ON RECORD. THIS IS STILL 0.4 DEGREES LOWER THAN THEIR
HIGHEST SEASONAL AVERAGE TEMPERATURE OF 83.1 SET IN 2010.


AVERAGE TEMPERATURE VALUES FOR SUMMER 2015 AT THE FOUR PRIMARY
CLIMATE SITES ACROSS EAST CENTRAL FLORIDA ARE AS FOLLOWS (RANKINGS
PROVIDED IF IN THE TOP 10):

-DAYTONA BEACH HAD AN AVERAGE TEMPERATURE FOR THE SEASON OF 81.9
DEGREES FAHRENHEIT, WHICH WAS 0.9 DEGREES ABOVE NORMAL. THIS TIED
WITH 2005 AS THE 6TH WARMEST SUMMER ON RECORD AT THIS LOCATION.

-ORLANDO HAD AN AVERAGE TEMPERATURE FOR THE SEASON OF 83.1 DEGREES
FAHRENHEIT, WHICH WAS 0.8 DEGREES ABOVE NORMAL. THIS RANKS AS THE
7TH WARMEST SUMMER ON RECORD FOR THIS LOCATION.

-MELBOURNE HAD AN AVERAGE TEMPERATURE FOR THE SEASON OF 81.5 DEGREES
FAHRENHEIT, WHICH WAS 0.2 DEGREES ABOVE NORMAL. THIS TIED WITH 1978
AS THE 9TH WARMEST SUMMER ON RECORD AT THIS LOCATION.

-VERO BEACH HAD AN AVERAGE TEMPERATURE FOR THE SEASON OF 82.7
DEGREES FAHRENHEIT, WHICH WAS 1.5 DEGREES ABOVE NORMAL. THIS TIED
WITH 1998 AS THE 2ND WARMEST SUMMER ON RECORD AT THIS LOCATION.


.RAINFALL...

GREATER COVERAGE OF SHOWERS AND STORMS IN JUNE WAS MAINLY LIMITED TO
EARLY AND LATE IN THE MONTH...AS A STRONG RIDGE SUPPRESSED
CONVECTION THROUGH MUCH OF MID JUNE. RAINFALL TOTALS FOR MANY
LOCATIONS ENDED UP BEING BELOW NORMAL FOR THE MONTH...ESPECIALLY
ALONG THE EAST COAST. DURING JULY AND AUGUST THE COMBINATION OF
FRONTAL TROUGHS THAT MOVED INTO NORTHERN FLORIDA AND A MORE DOMINANT
OFFSHORE FLOW THAT STEERED CONVECTION TOWARD THE AREA...LED TO AN
INCREASE IN PRECIPITATION FOR MUCH OF THE REGION. IN ADDITION...DEEP
TROPICAL MOISTURE USHERED IN BY THE REMNANTS OF ERIKA LED TO HIGH
COVERAGE OF SHOWERS IN STORMS AT THE END OF AUGUST.

DUE TO THE OFTEN SCATTERED COVERAGE OF AFTERNOON SHOWERS AND STORMS
AND PERIODS OF LOCALIZED HEAVY RAINFALL...TOTAL PRECIPITATION
AMOUNTS FOR THE SEASON VARIED QUITE A BIT ACROSS THE REGION. ORLANDO
MELBOURNE AND SANFORD HAD RAINFALL AMOUNTS THAT WERE 6 TO 8 INCHES
ABOVE NORMAL...RANKING IN THEIR TOP TEN WETTEST SUMMERS ON RECORD.
WHILE DRIER CONDITIONS ALONG THE TREASURE COAST LED TO STUART
EXPERIENCING THEIR DRIEST SUMMER ON RECORD WITH A MORE EXTREME
PRECIPITATION DEFICIT OF 12 INCHES FOR THE SEASON. DESPITE THESE
LARGE LOCALIZED DIFFERENCES...RAINFALL FOR MANY LOCATIONS CAME
WITHIN 80 TO 100 PERCENT OF NORMAL.
