...JANUARY 2012 WAS THE DRIEST JANUARY ON RECORD FOR MUCH OF EAST
CENTRAL FLORIDA...

A COUPLE OF STRONG COLD FRONTS MOVED THROUGH THE AREA DURING THE
FIRST HALF OF JANUARY...BRINGING SIGNIFICANTLY COLDER WEATHER TO
THE REGION. OTHERWISE THE REST OF THE MONTH REMAINED PLEASANT WITH
TEMPERATURES NEAR TO ABOVE NORMAL. THE FRONTAL BOUNDARIES THAT
CROSSED CENTRAL FLORIDA THIS MONTH WERE LACKING IN MOISTURE AND
THEREFORE PRODUCED LITTLE TO NO RAINFALL. THIS LACK OF PRECIPITATION
LED TO THE DRIEST JANUARY ON RECORD FOR MANY OBSERVING LOCATIONS
ACROSS EAST CENTRAL FLORIDA.

.TEMPERATURES...

A STRONG COLD FRONT MOVED THROUGH THE AREA ON THE 2ND OF THE MONTH.
THE COLDER AIRMASS THAT BUILT INTO THE AREA BEHIND THIS BOUNDARY
PRODUCED AVERAGE TEMPERATURES UP TO 15 TO 20 DEGREES BELOW NORMAL
FOR A FEW DAYS AFTERWARDS. BOTH MELBOURNE AND VERO BEACH BROKE
RECORD COOL HIGHS ON THE 3RD AND MELBOURNE TIED THE RECORD LOW EARLY
THAT MORNING. IN ADDITION...TEMPERATURES AT OR BELOW FREEZING
OCCURRED OVER MUCH OF THE AREA DURING THE EARLY MORNINGS OF THE 4TH
AND 5TH. A WEAK FRONT MOVED THROUGH FLORIDA ON THE 11TH...BUT WAS
THEN QUICKLY FOLLOWED BY A STRONG SECONDARY COLD FRONT THAT PRODUCED
AVERAGE TEMPERATURE DEPARTURES BETWEEN 10 TO 15 DEGREES BELOW NORMAL
DURING THE MIDDLE OF JANUARY.

DURING THE THE LATTER HALF OF THE MONTH ONLY A COUPLE OF WEAK
FRONTAL BOUNDARIES MOVED THROUGH THE AREA WITH TEMPERATURES
REMAINING NEAR TO ABOVE NORMAL. HIGHS IN THE UPPER 70S TO LOW 80S
WERE NOT UNCOMMON TOWARD THE END OF JANUARY WITH EVEN A FEW AREAS
OVER THE INTERIOR THAT HAD HIGHS IN THE MID 80S ON THE 26TH.

THE WARMER TEMPERATURES IN THE LAST HALF OF JANUARY WERE OFFSET BY
THE BRIEF BUT MUCH COLDER THAN NORMAL PERIODS DURING THE FIRST HALF.
THIS LED TO MONTHLY AVERAGE TEMPERATURES THAT WERE VERY CLOSE TO
NORMAL...ONLY RANGING FROM SLIGHTLY BELOW TO ONE DEGREE ABOVE
NORMAL.

THE AVERAGE TEMPERATURE VALUES FOR JANUARY 2012 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 58.7 DEGREES
FAHRENHEIT, WHICH WAS 0.8 DEGREES ABOVE NORMAL.

-ORLANDO HAD AN AVERAGE MONTHLY TEMPERATURE OF 60.2 DEGREES
FAHRENHEIT, WHICH WAS EQUAL TO NORMAL.

-MELBOURNE HAD AN AVERAGE MONTHLY TEMPERATURE OF 61.3 DEGREES
FAHRENHEIT, WHICH WAS 1.0 DEGREES ABOVE NORMAL.

-VERO BEACH HAD AN AVERAGE MONTHLY TEMPERATURE OF 61.9 DEGREES
FAHRENHEIT, WHICH WAS 0.2 DEGREES BELOW NORMAL.


.RAINFALL...

THE WINTER MONTHS DURING LA NINA PERIODS (CHARACTERIZED BY COOLER SEA
SURFACE TEMPERATURES IN THE TROPICAL PACIFIC) ARE TYPICALLY DRIER
THAN NORMAL ACROSS FLORIDA. LA NINA CONDITIONS IN THE PACIFIC
USUALLY LEAD TO A FARTHER NORTHWARD SHIFT OF THE JET STREAM AWAY
FROM FLORIDA DURING THIS TIMEFRAME. THIS IN TURN LEADS TO FEWER
STORM SYSTEMS AND THEREFORE LESS PRECIPITATION ACROSS THE STATE.

THESE DRY CONDITIONS CERTAINLY HELD TRUE THIS JANUARY FOR EAST
CENTRAL FLORIDA...HOWEVER THE LACK OF RAINFALL WAS QUITE EXTREME.
THE COLD FRONTS THAT PUSHED THROUGH THE REGION LACKED SIGNIFICANT
MOISTURE AND ONLY PRODUCED LIGHTER SHOWER ACTIVITY OVER THE AREA.
ISOLATED TO SCATTERED RAINFALL AMOUNTS OF A TENTH OF AN INCH OR LESS
WERE GENERALLY OBSERVED ON THE 2ND, 11TH, 18TH, AND 27TH WITH THESE
FRONTAL PASSAGES. MOST OBSERVING SITES HAD RAINFALL TOTALS FOR THE
MONTH THAT WERE ONLY AROUND 5 PERCENT OF NORMAL OR LESS. MELBOURNE
AND VERO BEACH ONLY RECEIVED TRACE AMOUNTS OF PRECIPITATION IN
JANUARY. AS OF THE 31ST BOTH OF THESE SITES HAVE GONE 35 CONSECUTIVE
DAYS WITHOUT MEASURABLE RAINFALL. THIS IS THE 4TH LONGEST DRY
STRETCH ON RECORD FOR MELBOURNE AND THE SECOND LONGEST DRY STRETCH
FOR VERO BEACH.
