...MARCH 2013 WAS ONE OF THE COLDEST ON RECORD AND MUCH DRIER THAN
NORMAL FOR EAST CENTRAL FLORIDA...

DESPITE MARCH BEING THE START TO CLIMATOLOGICAL SPRING...COLDER THAN
NORMAL TEMPERATURES FOR MUCH OF THE MONTH MADE IT FEEL MORE LIKE
WINTER. THIS MARCH WAS ONE OF THE COLDEST ON RECORD AND IN A RARE
OCCURRENCE WAS ALSO COLDER THAN ANY OF THE PAST MONTHS THIS WINTER!
WHILE COLD FRONTS THAT MOVED THROUGH THE REGION BROUGHT STRONG
TEMPERATURE CHANGES...LITTLE PRECIPITATION OCCURRED WITH THESE
BOUNDARIES. THIS HAS CONTINUED WHAT HAS BEEN A DRIER THAN NORMAL
TREND SO FAR THIS YEAR.

.TEMPERATURES...

A STRONG COLD FRONT PUSHED SOUTH OF CENTRAL FLORIDA EARLY ON THE
FIRST DAY OF MARCH...USHERING IN SIGNIFICANTLY COLDER WEATHER.
NORTHWEST FLOW MAINTAINED COLDER TEMPERATURES OVER THE AREA FOR THE
NEXT SEVERAL DAYS WITH THE 2ND THROUGH THE 4TH AVERAGING BETWEEN 12
TO 20 DEGREES BELOW NORMAL. ALSO...FREEZING TEMPERATURES OCCURRED
FOR SEVERAL AREAS EARLY ON THE 4TH WITH ORLANDO DROPPING BELOW 32
DEGREES FOR THE FIRST TIME SINCE EARLY LAST YEAR. FOR THE REST OF
THE MONTH A SERIES OF STRONG COLD FRONTS MOVED THROUGH THE REGION
WITH ONLY BRIEF PERIODS OF WARMER WEATHER IN BETWEEN. THE 23RD AND
24TH WERE ESPECIALLY WARM WITH MELBOURNE AND VERO BEACH TYING OR
BREAKING THEIR RECORD HIGHS WITH TEMPERATURES REACHING AROUND 90
DEGREES. THE COLDER AIRMASS THAT MOVED INTO THE AREA ON THE 25TH
KEPT TEMPERATURES WELL BELOW NORMAL FOR MUCH OF THE END OF MARCH.
THIS PUT THE FINAL NAIL IN THE COFFIN TO MARK THIS MARCH AS ONE OF
THE COLDEST ON RECORD WITH AVERAGE TEMPERATURE DEPARTURES FOR THE
MONTH BETWEEN 5 TO 6 DEGREES BELOW NORMAL.

WHILE NOT TOO SURPRISING AFTER WHAT WAS ONE OF THE MOST WARMEST
WINTERS ON RECORD...THE AVERAGE TEMPERATURE THIS MARCH WAS LOWER
THAN THIS PAST DECEMBER, JANUARY AND FEBRUARY. HOWEVER THIS IS
ACTUALLY A PRETTY RARE OCCURRENCE AND HAS ONLY HAPPENED ON RECORD IN
1932 AND 1949 (SEE BELOW). THE NEGATIVE PHASE OF THE ARCTIC
OSCILLATION WHICH PERSISTED FOR MUCH OF THE MONTH WAS THE PRIMARY
INFLUENCING FACTOR THAT LED TO SUCH AN EXTREMELY COLD MARCH. IN THIS
PHASE THERE TENDS TO BE A GREATER NUMBER OF COLD AIR OUTBREAKS
ACROSS THE CENTRAL AND EASTERN UNITED STATES.
