PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE MELBOURNE FL
549 AM EDT SAT MAY 2 2015

...WARMEST APRIL ON RECORD FOR MUCH OF EAST CENTRAL FLORIDA...
...RAINFALL WAS WELL ABOVE NORMAL DURING APRIL 2015...

THE ABNORMALLY WARM WEATHER THAT OCCURRED IN MARCH CONTINUED THROUGH
APRIL...MAGNIFIED BY A MORE DOMINANT HIGH PRESSURE RIDGE OVER THE
REGION. THIS PATTERN BLOCKED STRONGER FRONTAL PASSAGES ACROSS THE
AREA WITH ANY WEAK COLD FRONTS TYPICALLY STALLING AND FADING OUT AS
THEY MOVED INTO CENTRAL FLORIDA. THESE BOUNDARIES KEPT SUFFICIENT
MOISTURE IN PLACE TO HELP GENERATE SHOWER AND THUNDERSTORM ACTIVITY
ON A DAILY BASIS...MORE TYPICAL OF THE WET SEASON. THIS LED TO WELL
ABOVE NORMAL RAINFALL ACROSS MUCH OF EAST CENTRAL FLORIDA.


.TEMPERATURES...

TEMPERATURES QUICKLY REBOUNDED BACK TO ABOVE NORMAL VALUES EARLY IN
THE MONTH AFTER A BRIEF COOL DOWN AT THE END OF MARCH. NO BREAKS
FROM THE WARMER WEATHER OCCURRED THROUGH APRIL AS FRONTS THAT MOVED
INTO THE REGION REMAINED VERY WEAK AND TYPICALLY FADED OUT SOON
AFTER MOVING INTO CENTRAL FLORIDA. EVEN AS RAINFALL INCREASED FROM
DAILY SEA BREEZE GENERATED SHOWERS AND STORMS INTO MID AND LATE
MONTH...ONSET OF CONVECTION WAS OFTEN DELAYED AND ALLOWED HIGHS TO
REACH INTO THE UPPER 80S AND EVEN LOW 90S ON SEVERAL OCCASIONS.
DAILY AVERAGE TEMPERATURE VALUES GENERALLY REMAINED BETWEEN 5 TO 10
DEGREES ABOVE NORMAL UNTIL THE THE 30TH WHEN A WEAK COLD FRONT
FINALLY MOVED THROUGH THE STATE AND PRODUCED NEAR TO SLIGHTLY BELOW
NORMAL TEMPERATURES.

THIS PROLONGED PERIOD OF WARMER THAN NORMAL WEATHER IN APRIL...LED
TO AVERAGE MONTHLY TEMPERATURES THAT WERE 6 TO 7 DEGREES ABOVE
NORMAL. THESE VALUES NOT ONLY BROKE RECORDS BUT SHATTERED THEM BY A
DEGREE OR MORE AT DAYTONA BEACH...MELBOURNE AND VERO BEACH. FOR
ORLANDO IT WAS THE SECOND WARMEST APRIL ON RECORD...BUT THIS SITE
ALSO HAS A MUCH LONGER PERIOD OF RECORD...GOING BACK TO 1892.

.RAINFALL...

DRIER THAN NORMAL CONDITIONS GENERALLY CARRIED OVER FROM MARCH INTO
THE FIRST SEVERAL DAYS OF APRIL. MOISTURE THEN GRADUALLY INCREASED
AHEAD OF A WEAK FRONT THAT STALLED NORTH OF THE AREA ON THE 11TH.
THIS LED TO A MORE SUMMER-LIKE PATTERN WITH SCATTERED SHOWERS AND
STORMS DEVELOPING ALONG SEA BREEZE BOUNDARIES INTO THE AFTERNOON AND
EVENING HOURS. DAILY CONVECTIVE DEVELOPMENT THEN GENERALLY PERSISTED
THROUGH MUCH OF THE REST OF THE MONTH AS MOISTURE LINGERED DUE TO
LACK OF FRONTAL PASSAGES ACROSS THE AREA. PASSING DISTURBANCES ALOFT
INCREASED COVERAGE OF SHOWERS AND STORMS AT TIMES WITH ISOLATED
SEVERE STORMS OCCURRING ACROSS THE REGION...MAINLY ON THE 19TH AND
27TH. MOST NOTABLE WAS THE LATTER OF THESE TWO DATES WHEN SEVERE
STORMS MOVED THROUGH OKEECHOBEE AND MARTIN COUNTIES...LEADING TO
NUMEROUS REPORTS OF DAMAGING HAIL MEASURING 1 TO 2 INCHES IN
DIAMETER.
