1 JAN 11 - (Excerpts) - NATIONAL WEATHER SVC MELBOURNE FL ... COLDEST
DECEMBER ON RECORD FOR EAST CENTRAL FLORIDA... RAINFALL ALSO WELL BELOW
NORMAL...
THREE SEPARATE FREEZE EVENTS WERE EXPERIENCED THIS DECEMBER ... ON THE
MORNINGS OF THE 7-8TH...14-16TH...AND 27-29TH.
DAILY AVERAGE TEMPERATURE DEPARTURES REMAINED BELOW NORMAL ALMOST EVERY
SINGLE DAY WITH DEPARTURES AS HIGH 15 TO 25 DEGREES BELOW NORMAL ON
SEVERAL DAYS. IN ADDITION...NUMEROUS RECORD LOWS AND COOL HIGHS WERE
BROKEN THROUGHOUT THE MONTH.
MONTHLY AVERAGE TEMPERATURE DEPARTURES ACROSS EAST CENTRAL FLORIDA WERE
9 TO 11 DEGREES BELOW NORMAL. THESE AVERAGE TEMPERATURE VALUES ...
SHATTERED THE PREVIOUS COLDEST DECEMBER RECORDS BY A WHOLE 2 TO 4
DEGREES. RECORDS GO AS FAR BACK AS THE EARLY 20S... EVEN COOP SITES THAT
HAVE DATA EXTENDING BACK INTO THE EARLY 1900S SUCH AS TITUSVILLE...FORT
PIERCE AND DELAND EXPERIENCED THEIR COLDEST DECEMBER ON RECORD BY A
LARGE MARGIN.
THE MAIN CONTRIBUTING FACTOR ... WAS A PERSISTENT AND STRONG NEGATIVE
PHASE OF THE
NORTH ATLANTIC OSCILLATION. THE NEGATIVE PHASE OF THE NORTH ATLANTIC
OSCILLATION TYPICALLY BRINGS MORE COLD AIR OUTBREAKS ALONG THE CENTRAL
AND EASTERN UNITED STATES.
