PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE MELBOURNE FL
405 AM EDT SAT APR 2 2011

...MARCH 2011 ACROSS MOST OF EAST CENTRAL FLORIDA WAS ABOVE NORMAL
IN BOTH TEMPERATURES AND RAINFALL...

IF THE OLD ADAGE IS THAT MARCH COMES IN LIKE A LION AND OUT LIKE A
LAMB...THEN THIS MARCH ACROSS EAST CENTRAL FLORIDA WAS THE EXACT
OPPOSITE. AN EXTREMELY STORMY LAST FEW DAYS OF THE MONTH ENDED A
GENERALLY DRY PATTERN THAT WAS OBSERVED THROUGH MUCH OF MARCH. THESE
STORMS PRODUCED WIDESPREAD HEAVY RAINFALL THAT PLACED MOST OF THE
AREA ABOVE NORMAL PRECIPITATION WISE. THE FRONTAL BOUNDARIES THAT
CROSSED THE REGION BROUGHT LITTLE IN THE WAY OF COOLER WEATHER TO
THE AREA AND IN THE END LED TO SLIGHTLY ABOVE NORMAL TEMPERATURES.

.TEMPERATURES...

COLD FRONTS CROSSED THE AREA LATE ON THE 6TH AND ON THE 10TH...
PROVIDING BRIEF COOL DOWNS ACROSS THE AREA. AVERAGE TEMPERATURES
AFTER THESE FRONTAL PASSAGES FELL TO AROUND 5 TO 10 DEGREES BELOW
NORMAL. OTHERWISE MUCH OF THE MONTH SAW NEAR TO ABOVE NORMAL
TEMPERATURES WITH HIGHS GENERALLY RANGING FROM THE MID 70S TO MID
80S. THE HIGHEST MAXIMUM TEMPERATURES DURING THE MONTH OCCURRED ON
THE 27TH WHEN STRONG WARM AIR ADVECTION AHEAD OF A COLD FRONT
ALLOWED TEMPERATURES TO RISE INTO THE LOW 90S OVER MUCH OF THE AREA.
THESE HIGHS BROKE OR TIED RECORDS AT DAYTONA BEACH...MELBOURNE AND
VERO BEACH. OVERALL FOR THE MONTH...AVERAGE TEMPERATURES REACHED
AROUND 1 TO 1.5 DEGREES ABOVE NORMAL.


THE AVERAGE TEMPERATURE VALUES FOR MARCH 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 MONTHLY TEMPERATURE OF 65.8 DEGREES
FAHRENHEIT WHICH WAS 1.1 DEGREES ABOVE NORMAL.

-ORLANDO HAD AN AVERAGE MONTHLY TEMPERATURE OF 69.0 DEGREES
FAHRENHEIT WHICH WAS 1.6 DEGREES ABOVE NORMAL.

-MELBOURNE HAD AN AVERAGE MONTHLY TEMPERATURE OF 67.7 DEGREES
FAHRENHEIT WHICH WAS 1.5 DEGREES ABOVE NORMAL.

-VERO BEACH HAD AN AVERAGE MONTHLY TEMPERATURE OF 68.1 DEGREES
FAHRENHEIT WHICH WAS 0.4 DEGREES ABOVE NORMAL.


.RAINFALL...

A FEW FRONTAL BOUNDARIES MOVED THROUGH THE AREA DURING THE FIRST
HALF OF MARCH AND BROUGHT WITH THEM SHOWERS AND EVEN A FEW
THUNDERSTORMS. THE HEAVIEST OF THIS RAINFALL OCCURRED WITH TWO
SEPARATE CONVECTIVE RAIN BANDS AHEAD OF A COLD FRONT THAT CROSSED
CENTRAL FLORIDA ON THE 10TH. TOTAL RAINFALL ACCUMULATIONS WERE
GENERALLY AROUND A HALF TO ONE INCH FOR MOST LOCATIONS WITH THIS
EVENT. HIGH PRESSURE THEN DOMINATED THE WEATHER PATTERN THROUGH MUCH
OF THE REST OF THE MONTH...LEADING TO A DRY WEATHER PATTERN. IN
FACT...NO RAINFALL WAS OBSERVED FROM THE 11TH THROUGH THE 27TH OF
MARCH.

HOWEVER THIS PATTERN CHANGED BY THE END OF THE MONTH AS DEEPER
MOISTURE MOVED INTO THE REGION AHEAD OF A FRONTAL BOUNDARY ON THE
28TH. A WIDESPREAD BAND OF SHOWERS AND STORMS MOVED ACROSS THE AREA
ON THAT DAY AND INTO THE EVENING WITH RAINFALL TOTALS AROUND 1-2
INCHES OVER MOST LOCATIONS WITH LOCALLY HIGHER AMOUNTS IN OSCEOLA
COUNTY AROUND 3-4 INCHES. THE FRONT SETTLED INTO CENTRAL FLORIDA ON
THE 29TH AND THEN LIFTED BACK NORTHWARD ON THE 30TH...SETTING OFF A
FAST MOVING BAND OF STRONG TO SEVERE STORMS. THESE STORMS PUSHED
THROUGH LAKE AND OSCEOLA COUNTIES EASTWARD TOWARD VOLUSIA AND
BREVARD COUNTIES...CAUSING WIDESPREAD STRAIGHT LINE WIND DAMAGE AND
EVEN A FEW REPORTS OF LARGE HAIL. ANOTHER ROUND OF SEVERE WEATHER
OCCURRED ON THE 31ST AS AN ADDITIONAL BAND OF SHOWERS AND STORMS
MOVED SOUTHEASTWARD ACROSS CENTRAL FLORIDA AHEAD OF A COLD FRONT.
SEVERAL REPORTS OF STRONG TO SEVERE WIND GUSTS AND HAIL WERE
REPORTED ONCE AGAIN WITH THIS LINE. IN ADDITION...VERY HEAVY
RAINFALL OCCURRED WITH THIS BAND MAINLY NORTH OF THE TREASURE COAST
WITH PRECIPITATION TOTALS UP TO 2-4 INCHES.

THE HEAVY RAINFALL EVENTS IN THE LAST 4 DAYS OF MARCH MADE UP MOST
OF THE RAINFALL FOR THE MONTH AND HELPED PROVIDE PRECIPITATION
AMOUNTS UP TO AROUND 150-200% OF NORMAL FOR MARCH. TO PUT THE END OF
THE MONTH TOTALS IN PERSPECTIVE...MOST LOCATIONS RECEIVED RAINFALL
AMOUNTS IN MARCH THAT WERE NEAR TO ABOVE THE TOTAL RAINFALL AMOUNTS
OBSERVED DURING THE ENTIRE CLIMATOLOGICAL WINTER SEASON
(DECEMBER-FEBRUARY). A FEW CO-OPERATIVE OBSERVER STATIONS HAD
RAINFALL AMOUNTS THAT RANKED IN THE TOP 10 WETTEST FOR THEIR
RESPECTIVE SITES. CLERMONT HAD THEIR 5TH WETTEST MARCH...SANFORD HAD
THEIR 7TH WETTEST MARCH...AND TITUSVILLE HAD THEIR 10 WETTEST MARCH
ON RECORD.
