...2012 WAS WARMER AND DRIER THAN NORMAL ACROSS EAST CENTRAL
FLORIDA...

A MUCH WARMER THAN NORMAL WINTER AND SPRING INTO 2012 WAS MODERATED
BY NEAR TO BELOW NORMAL TEMPERATURES IN THE SUMMER AND FALL MONTHS.
OVERALL HOWEVER AVERAGE TEMPERATURES FOR THE YEAR ENDED UP ABOVE
NORMAL. LA NINA CONDITIONS CONTRIBUTED TO A VERY DRY START TO THE
YEAR THAT CONTINUED INTO MUCH OF THE SPRING. RAINFALL PICKED UP INTO
THE NORMAL START OF THE WET SEASON BUT DROPPED OFF AGAIN INTO THE
FALL AND WINTER MONTHS. DUE TO THE GREATER MAGNITUDE AND EXTENDED
LENGTH OF DRIER THAN NORMAL PERIODS THROUGH THE YEAR...PRECIPITATION
VALUES WERE BELOW NORMAL OVER MUCH OF THE REGION.

.2012 YEAR IN REVIEW...

JANUARY-FEBRUARY...

A STRONG COLD FRONT MOVED THROUGH THE AREA DURING THE START OF 2012.
THE COLDEST LOW TEMPERATURES THROUGHOUT THE ENTIRE YEAR OCCURRED
BEHIND THIS BOUNDARY ON JANUARY 5TH...WITH TEMPERATURES AT OR BELOW
FREEZING FOR MOST LOCATIONS EARLY THAT MORNING. DESPITE THIS
SIGNIFICANT COOL DOWN...TEMPERATURES DURING THE LATTER HALF OF
JANUARY AND INTO FEBRUARY WERE WARMER THAN NORMAL AS THE POSITIVE
PHASE OF THE ARCTIC OSCILLATION LED TO FEWER COLD AIR OUTBREAKS OVER
THE EASTERN UNITED STATES. IN FACT...AVERAGE TEMPERATURE DEPARTURES
FOR FEBRUARY WERE AROUND 4 TO 5 DEGREES ABOVE NORMAL...WHICH WAS THE
7TH WARMEST AND 10TH WARMEST FEBRUARY ON RECORD FOR DAYTONA BEACH
AND VERO BEACH RESPECTIVELY.

IT WAS ALSO A VERY DRY PERIOD AS ONGOING LA NINA CONDITIONS SHIFTED
THE JET STREAM FARTHER NORTH OF FLORIDA WITH FEWER STORM SYSTEMS
CROSSING THE AREA. THE DRIEST JANUARY ON RECORD OCCURRED IN 2012
WITH RAINFALL AMOUNTS ONLY AROUND 5 PERCENT OF NORMAL OR LESS.
MELBOURNE AND VERO BEACH DID NOT RECEIVE ANY MEASURABLE RAINFALL
THROUGH JANUARY INTO EARLY FEBRUARY WHICH ENDED UP BEING THE 2ND
LONGEST "DRY" STRETCH EVER ON RECORD FOR BOTH SITES. BELOW NORMAL
RAINFALL CONTINUED THROUGH MUCH OF THE REST OF FEBRUARY WITH A BRIEF
INCREASE IN PRECIPITATION TOWARD THE END OF THE MONTH. THESE OVERALL
DRIER THAN NORMAL CONDITIONS LED TO THE DEVELOPMENT OF MODERATE TO
SEVERE DROUGHT IMPACTS OVER THE REGION.

MARCH-MAY...

LA NINA CONDITIONS OVER THE EQUATORIAL PACIFIC WEAKENED AND
EVENTUALLY ENDED IN THE SPRING. HOWEVER ITS INFLUENCE OVER THE AREA
HELPED CONTINUE WARMER AND DRIER THAN NORMAL CONDITIONS FOR MUCH OF
THE SEASON. THIS PATTERN COMBINED WITH AN ANOMALOUS RIDGE OVER MUCH
OF THE CENTRAL AND EASTERN UNITED STATES IN MARCH TO GENERATE VERY
WARM TEMPERATURES FOR THE MONTH. MARCH ACTUALLY RANKED IN THE TOP 6
WARMEST ON RECORD FOR THE PRIMARY CLIMATE SITES OF DAYTONA BEACH...
ORLANDO...MELBOURNE...AND VERO BEACH WITH AVERAGE TEMPERATURE
DEPARTURES BETWEEN 4 TO 6 DEGREES ABOVE NORMAL. WHILE NOT AS EXTREME
AS MARCH...TEMPERATURES IN APRIL AND MAY AVERAGED WARMER THAN NORMAL
WITH ONLY A COUPLE BRIEF COOL DOWNS THROUGH THIS PERIOD. THE SPRING
SEASON IN 2012 WILL BE REMEMBERED AS BEING ONE OF THE WARMEST ON
RECORD FOR THE AREA...WITH MELBOURNE ACTUALLY BREAKING ITS PREVIOUS
RECORD SET BACK IN 1974.

RAINFALL WAS GENERALLY LIMITED INTO MUCH OF MARCH AND APRIL AS
FRONTAL BOUNDARIES DURING THIS TIMEFRAME WERE RATHER WEAK. THIS
CONTINUED TO WORSEN THE DROUGHT OVER THE REGION WITH EXTREME DROUGHT
CONDITIONS DEVELOPING OVER LAKE AND VOLUSIA COUNTIES. TOTAL
PRECIPITATION IN MARCH WAS ONLY AROUND 50 PERCENT OF NORMAL OR LESS
AND BETWEEN 60 TO 80 PERCENT IN APRIL. RAINFALL FINALLY BEGAN TO
INCREASE OVER THE AREA INTO EARLY MAY WITH THE APPROACH OF A FRONTAL
BOUNDARY. LINGERING MOISTURE FROM THIS BOUNDARY HELPED INITIATE
ALMOST DAILY ISOLATED TO SCATTERED SHOWER AND THUNDERSTORM ACTIVITY
THROUGH MAY. PRECIPITATION FROM THIS CONVECTION AND RAINS FROM
TROPICAL STORM BERYL PROVIDED MONTH END RAINFALL TOTALS THAT WERE
NEAR TO ABOVE NORMAL FOR THE FIRST TIME IN 2012.

JUNE-AUGUST...

A MORE DISTURBED WEATHER PATTERN DEVELOPED EARLY IN THE SUMMER WITH
INCREASED CLOUDINESS AND RAINFALL OVER THE AREA IN JUNE. TROPICAL
STORM DEBBY DEVELOPED OVER THE GULF OF MEXICO LATE IN THE MONTH AND
CROSSED INTO NORTH FLORIDA AS IT WEAKENED TO A DEPRESSION. THIS
SYSTEM PRODUCED CONSIDERABLE PRECIPITATION AMOUNTS UP TO 5 TO 8
INCHES ACROSS LAKE AND NORTHWEST VOLUSIA COUNTIES. GREATER CLOUD
COVER AND HEAVY RAINS DURING JUNE LED TO AVERAGE TEMPERATURES THAT
WERE BELOW NORMAL AND RAINFALL AMOUNTS THAT WERE WELL ABOVE
NORMAL...EXCEPT ALONG THE TREASURE COAST. THE HEALTHIER RAINFALL
AMOUNTS FROM MAY AND JUNE COMBINED TO EASE AND FINALLY END DROUGHT
CONDITIONS OVER THE REGION.

TEMPERATURES INTO THE REST OF THE SUMMER GENERALLY REMAINED AROUND
NORMAL INTO MUCH OF JULY AND AUGUST. LARGER INFLUENCE OF THE SURFACE
ATLANTIC HIGH PRESSURE RIDGE AND THE ABSENCE OF TROPICAL ACTIVITY
IN JULY GENERATED DRIER THAN NORMAL CONDITIONS OVER THE REGION. THEN
A MORE PREVALENT SOUTHWEST FLOW IN AUGUST CONCENTRATED AFTERNOON
CONVECTION OVER EAST CENTRAL FLORIDA AND COMBINED WITH HEAVY RAINS
FROM TROPICAL STORM ISSAC TO PRODUCE ABOVE NORMAL RAINFALL TOWARD
THE END OF THE SUMMER.

SEPTEMBER-DECEMBER...

FRONTAL BOUNDARIES THROUGH THE FIRST HALF OF FALL WERE FAIRLY WEAK
AND TEMPERATURES DURING THIS TIME-FRAME REMAINED GENERALLY AROUND
NORMAL. THIS CHANGED HOWEVER INTO LATE OCTOBER AS STRONGER COLD
FRONTS MOVED THROUGH THE REGION. A COLD FRONT THAT MOVED ACROSS
THE AREA AS TROPICAL CYCLONE SANDY SHIFTED NORTHEAST AWAY FROM
FLORIDA...DROPPED TEMPERATURES TO 10 TO 15 DEGREES BELOW NORMAL
DURING THE LAST FEW DAYS OF OCTOBER. SEVERAL ADDITIONAL COLD FRONTS
MOVED THROUGH THE AREA IN NOVEMBER AND PROVIDED MORE PERSISTENT
NORTHERLY FLOW AND COOLER TEMPERATURES. AVERAGE TEMPERATURES FOR THE
MONTH WERE AROUND 4 DEGREES BELOW NORMAL...WHICH RANKED AS THE 7TH
COLDEST NOVEMBER FOR DAYTONA BEACH AND VERO BEACH AND 8TH COLDEST
FOR MELBOURNE. WARMER THAN NORMAL TEMPERATURES RETURNED INTO MUCH OF
DECEMBER DESPITE A FEW STRONGER COLD FRONTAL PASSAGES INTO THE
LATTER HALF OF THE MONTH.

RAINFALL GENERALLY DECREASED OVER THE AREA INTO THE FALL AS THE
TYPICAL WET SEASON NEARED ITS END. INCREASED CONVECTION AHEAD OF A
FRONT IN EARLY OCTOBER AND OUTER RAINBANDS FROM TROPICAL CYCLONE
SANDY DID HELP BRING UP PRECIPITATION TOTALS DURING THE MIDDLE OF
THE SEASON. HOWEVER A VERY DRY NOVEMBER ENDED UP LEADING TO FALL
RAINFALL TOTALS THAT WERE GENERALLY 3 TO 8 INCHES BELOW NORMAL.
DRIER THAN NORMAL CONDITIONS CONTINUED INTO EARLY DECEMBER BEFORE
RAINFALL EVENTS INCREASED WITH THE PASSAGES OF A FEW FRONTAL
BOUNDARIES TOWARD THE MIDDLE AND LATTER HALF OF THE MONTH. SEVERE
WEATHER OCCURRED WITH A COLD FRONT THAT MOVED THROUGH THE REGION ON
DECEMBER 10TH...INCLUDING THE FIRST EF-1 TORNADO IN THE EAST CENTRAL
FLORIDA AREA SINCE AUGUST 2008. THIS TORNADO TOUCHED DOWN IN THE
TOWN OF EDGEWATER WITH ESTIMATED WINDS OF 90-110 MPH AND PRODUCED
SIGNIFICANT DAMAGE TO THE AREA.
