PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE MELBOURNE FL
738 PM EDT THU JUN 2 2011

...ABOVE NORMAL TEMPERATURES OCCURRED OVER EAST CENTRAL FLORIDA
DURING SPRING 2011...

WEAKER COLD FRONTS MOVED THROUGH THE AREA DURING THE SPRING SEASON
AND ALLOWED FOR LONGER PERIODS OF WARMER THAN NORMAL CONDITIONS
ACROSS EAST CENTRAL FLORIDA. MOST OF THESE BOUNDARIES LACKED
WIDESPREAD PRECIPITATION EXCEPT FOR A FEW STRONGER FRONTS IN LATE
MARCH AND EARLY APRIL. THE WIDESPREAD HEAVY RAINFALL THAT OCCURRED
WITH THESE SYSTEMS PRODUCED A SIGNIFICANT PORTION OF THE
PRECIPITATION OBSERVED THIS SEASON...ESPECIALLY NORTH OF OKEECHOBEE
COUNTY AND THE TREASURE COAST.

.TEMPERATURES...

THE POSITIVE PHASE OF THE ARCTIC OSCILLATION WHICH DEVELOPED BY LATE
WINTER CONTINUED INTO MUCH OF THE SPRING. THIS PHASE IS ASSOCIATED
WITH FEWER ARCTIC AIR OUTBREAKS ALONG THE EAST COAST OF THE UNITED
STATES. IN ADDITION...WEAKENING LA NINA CONDITIONS OVER THE
EQUATORIAL PACIFIC HAD LINGERING IMPACTS OVER THE UNITED STATES THIS
SEASON WHICH FAVORS WARMER THAN NORMAL TEMPERATURES ACROSS FLORIDA.
THIS SPRING SEASON DID NOT DISAPPOINT WITH MARCH...APRIL AND MAY
EXPERIENCING ABOVE TO WELL ABOVE NORMAL MONTHLY AVERAGE TEMPERATURES
OVER THE REGION. APRIL SAW THE LARGEST DEPARTURES FROM NORMAL WITH
MONTHLY AVERAGE TEMPERATURES AS HIGH AS 3 TO 4 DEGREES ABOVE NORMAL.
DAYTONA BEACH HAD THE 10TH WARMEST APRIL ON RECORD...ORLANDO THE 5TH
WARMEST...MELBOURNE THE 6TH WARMEST...AND VERO BEACH THE 4TH
WARMEST.

OVERALL...SPRING AVERAGE TEMPERATURE VALUES WERE AROUND 1 TO 2
DEGREES ABOVE NORMAL. THIS WAS ONE OF THE WARMEST SPRINGS ON
RECORD...RANKING IN THE TOP 10 FOR 3 OUT OF THE 4 MAJOR CLIMATE
SITES IN EAST CENTRAL FLORIDA.

THE AVERAGE TEMPERATURE VALUES FOR THE SPRING SEASON 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 SPRING SEASON TEMPERATURE OF 71.2

.RAINFALL...

LA NINA CONDITIONS OVER THE EQUATORIAL PACIFIC CONTINUED A DRIER
THAN NORMAL PATTERN THROUGHOUT MUCH OF THE SPRING. THE EXCEPTION WAS
FROM LATE MARCH INTO EARLY APRIL...OR THE PERIOD FROM MARCH 28TH TO
APRIL 5TH...WHEN SEVERAL BANDS OF STRONG TO SEVERE STORMS PUSHED
ACROSS THE AREA. IN ADDITION TO WIND AND HAIL DAMAGE...THESE SYSTEMS
BROUGHT WIDESPREAD HEAVY RAINFALL TO MUCH OF EAST CENTRAL FLORIDA.
RAINFALL TOTALS DURING THIS PERIOD REACHED UPWARDS TO 5 TO 8 INCHES
FROM OSCEOLA AND BREVARD COUNTY...NORTHWARD TO LAKE AND VOLUSIA
COUNTIES. FARTHER SOUTH RAINFALL AMOUNTS WERE NOT AS HIGH...BUT
STILL TOTALED AROUND 2 TO 3 INCHES. AFTER THESE EVENTS...MUCH DRIER
THAN NORMAL CONDITIONS RETURNED TO THE AREA. RAINFALL DEPARTURES FOR
MUCH OF EAST CENTRAL FLORIDA IN APRIL WERE AROUND 1 TO 2 INCHES
BELOW NORMAL AND IN MAY WERE ROUGHLY BETWEEN 2 AND 4 INCHES BELOW
NORMAL.

RAINFALL DEPARTURES FOR SPRING HAD A CONSIDERABLE RANGE ACROSS EAST
CENTRAL FLORIDA. NEAR NORMAL TO SLIGHTLY BELOW NORMAL RAINFALL
OCCURRED ACROSS LAKE...SEMINOLE...ORANGE...WESTERN OSCEOLA AND
NORTHERN BREVARD COUNTIES. THIS WAS LARGELY ATTRIBUTED TO WHERE THE
HEAVIEST RAINFALL FELL DURING THE STORMY PERIOD OF LATE MARCH TO
EARLY APRIL. BELOW TO WELL BELOW NORMAL RAINFALL WAS OBSERVED ACROSS
VOLUSIA...EASTERN OSCEOLA...SOUTHERN BREVARD...OKEECHOBEE...AND THE
TREASURE COAST COUNTIES.  THE LARGEST NEGATIVE RAINFALL DEPARTURES
OCCURRED ALONG THE TREASURE COAST FROM INDIAN RIVER COUNTY TO MARTIN
COUNTY...WESTWARD TO OKEECHOBEE COUNTY WHERE PRECIPITATION AMOUNTS
WERE ONLY AROUND 50 PERCENT OF NORMAL.

WHILE PLACES THAT RECEIVED MORE NORMAL RAINFALL THIS SPRING HAVE
SEEN SOME SLIGHT IMPROVEMENT IN DROUGHT CONDITIONS...ALONG THE EAST
COAST AND INTO THE SOUTHERN INTERIOR...SEVERE TO EXTREME DROUGHT
CONDITIONS PERSIST.
