PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE MELBOURNE FL
314 PM EST TUE FEB 1 2011

...BELOW NORMAL TEMPERATURES CONTINUED ACROSS MUCH OF EAST CENTRAL
FLORIDA DURING JANUARY 2011...
...SEVERAL HEAVY RAINFALL EVENTS BROUGHT NEAR TO ABOVE NORMAL
RAINFALL TO THE AREA DURING THE MONTH...

THE PASSAGE OF COLD FRONTS AND STORM SYSTEMS OVER THE AREA INCREASED
THIS WINTER IN THE MONTH OF JANUARY 2011. THIS LED TO NEAR TO ABOVE
NORMAL RAINFALL ACROSS THE ENTIRE AREA...WHICH HAS NOT OCCURRED
SINCE APRIL OF LAST YEAR. HOWEVER WHILE THIS RAINFALL WAS
BENEFICIAL...LONGER TERM RAINFALL DEFICITS CONTINUE TO CREATE SEVERE
TO EXTREME DROUGHT CONDITIONS ACROSS THE AREA. THESE SYSTEMS ALSO
BROUGHT SEVERAL PERIODS OF COLDER WEATHER INTO THE STATE WHICH LED
TO BELOW NORMAL TEMPERATURES OVERALL FOR THE REGION. THIS CONTINUES
A WINTER THAT IS SHAPING UP TO BE ONE OF THE COLDEST ON RECORD.

.TEMPERATURES...

THE NEW YEAR STARTED OFF PLEASANT WITH ABOVE NORMAL TEMPERATURES
ACROSS EAST CENTRAL FLORIDA...BUT A COLD FRONT THAT CROSSED THE AREA
ON THE 3RD BEGAN A STRING OF MORE SIGNIFICANT FRONTS THAT WOULD
TRAVERSE THE AREA DURING THE MONTH. THESE STRONGER COLD FRONTS MOVED
THROUGH CENTRAL FLORIDA ON THE 6TH...11TH...21ST...AND 26TH OF
JANUARY AND ALL BROUGHT TEMPERATURE DEPARTURES AROUND 10 TO 15
DEGREES BELOW NORMAL AFTER PASSAGE. THE COLDEST DAY THIS MONTH
OCCURRED ON THE 13TH WHEN FREEZING TEMPERATURES WERE EXPERIENCED
ACROSS MUCH OF THE AREA DURING THE EARLY MORNING HOURS. DAYTONA
BEACH EVEN RECORDED A RECORD COOL HIGH TEMPERATURE VALUE FOR THE DAY
OF 47 DEGREES FAHRENHEIT. WHILE AVERAGE TEMPERATURE DEPARTURES FOR
MOST SITES AT THE END OF THE MONTH WERE AROUND 1 TO 3 DEGREES BELOW
NORMAL...THIS WAS NOT ONE OF THE COLDEST JANUARIES THAT HAVE BEEN
OBSERVED. IN FACT NONE OF THE CLIMATE SITES IN THE AREA RANKED IN
THE TOP 10 COLDEST JANUARIES ON RECORD.

STILL...WITH THE BELOW NORMAL TEMPERATURE TREND CONTINUING IN
JANUARY AND WITH AN EXTREMELY COLD PERIOD OBSERVED THIS PAST
DECEMBER...THIS WINTER...SO FAR...IS ONE OF THE COLDEST ON RECORD.

TOP 5 COLDEST DEC-JAN AVERAGE TEMPERATURE RANKINGS IN DEGREES

THE OVERALL JANUARY MONTHLY AVERAGE TEMPERATURE VALUES FOR THE FOUR
MAIN CLIMATE SITES ACROSS EAST CENTRAL FLORIDA ARE AS FOLLOWS:

-DAYTONA BEACH HAD AN AVERAGE MONTHLY TEMPERATURE OF 55.2 DEGREES
FAHRENHEIT WHICH WAS 3.2 DEGREES BELOW NORMAL.

-ORLANDO HAD AN AVERAGE MONTHLY TEMPERATURE OF 59.4 DEGREES
FAHRENHEIT WHICH WAS 1.5 DEGREES BELOW NORMAL.

-MELBOURNE HAD AN AVERAGE MONTHLY TEMPERATURE OF 61.5 DEGREES
FAHRENHEIT WHICH WAS 0.6 DEGREES ABOVE NORMAL.

-VERO BEACH HAD AN AVERAGE MONTHLY TEMPERATURE OF 60.5 DEGREES
FAHRENHEIT WHICH WAS 2.5 DEGREES BELOW NORMAL.


.RAINFALL...

THROUGH THE FIRST HALF OF JANUARY...A FEW COLD FRONTS CROSSED
CENTRAL FLORIDA. HOWEVER PRECIPITATION ALONG THESE BOUNDARIES WAS
FAIRLY MEAGER...WITH THE EXCEPTION OF MORE WIDESPREAD RAINFALL THAT
FELL WITH A BAND OF SHOWERS AND ISOLATED STORMS AHEAD OF A FRONT ON
THE 5TH AND 6TH. THE HEAVIEST RAINFALL FROM THIS SYSTEM FELL OVER
NORTHERN LAKE AND VOLUSIA COUNTIES WHERE SOME LOCALLY HEAVY RAINFALL
OF 1 TO 2 INCHES WAS REPORTED IN SOME SPOTS.

IT WAS NOT UNTIL THE LATTER HALF OF JANUARY THAT THE BULK OF THE
MORE HEAVY RAINFALL EVENTS WERE OBSERVED...ESPECIALLY OVER NORTHERN
PORTIONS OF EAST CENTRAL FLORIDA. TOTAL RAINFALL AMOUNTS OF 3 TO 5
INCHES WERE OBSERVED FROM LAKE AND VOLUSIA COUNTIES...SOUTHWARD TO
OSCEOLA AND BREVARD COUNTIES DURING THIS TIMEFRAME. OVER OKEECHOBEE
AND THE TREASURE COAST RAINFALL AMOUNTS WERE NOT AS HIGH...BUT WERE
STILL NEAR TO ABOVE NORMAL FOR THE MONTH. THESE WIDESPREAD RAINFALL
AMOUNTS ALLOWED FOR SOME IMPROVEMENT IN THE MORE SHORT TERM DROUGHT
CONDITIONS ACROSS EAST CENTRAL FLORIDA. HOWEVER SEVERE TO EXTREME
DROUGHT CONTINUES TO PERSIST OVER MUCH OF THE AREA DUE TO AN
EXTENDED DRY PATTERN EXPERIENCED DURING MUCH OF LAST YEAR. ACROSS
THE REGION...RAINFALL TOTALS FOR JANUARY WERE GENERALLY AROUND 100
TO 150 PERCENT OF NORMAL WITH SOME LOCALLY HIGHER VALUES OVER NORTH
CENTRAL FLORIDA.

IT WAS SLIGHTLY UNUSUAL TO SEE THESE MORE HEALTHY RAINFALL AMOUNTS
OCCUR DURING A WINTER MONTH WHEN LA NINA CONDITIONS ARE PRESENT OVER
THE EQUATORIAL PACIFIC WATERS. HOWEVER A MEAN TROUGH OVER THE
EASTERN UNITED STATES...DUE TO A LINGERING NEGATIVE PHASE OF THE
ARCTIC OSCILLATION...LED TO A MORE ACTIVE AND SOUTHWARD PLACEMENT OF
THE JET STREAM OVER THE SOUTHEAST UNITED STATES. THIS POSITION OF
THE JET STREAM HELPED TRANSPORT MORE STORM SYSTEMS ACROSS FLORIDA
AND MORE WIDESPREAD RAINFALL.

THE OVERALL RAINFALL TOTALS FOR THE FOUR MAIN CLIMATE SITES ACROSS
EAST CENTRAL FLORIDA ARE AS FOLLOWS (RANKINGS PROVIDED IF IN THE TOP
10):

-DAYTONA BEACH RECEIVED 4.37 INCHES OF RAINFALL WHICH WAS 1.24
INCHES ABOVE NORMAL.

-ORLANDO RECEIVED 5.92 INCHES OF RAINFALL WHICH WAS 3.49 INCHES
ABOVE NORMAL. THIS IS THE 5TH WETTEST JANUARY ON RECORD FOR THIS
SITE.

-MELBOURNE RECEIVED 4.09 INCHES OF RAINFALL WHICH WAS 1.61 INCHES
ABOVE NORMAL. THIS IS THE 9TH WETTEST JANUARY ON RECORD FOR THIS
SITE.

-VERO BEACH RECEIVED 3.02 INCHES OF RAINFALL WHICH WAS 0.13 INCHES
ABOVE NORMAL.
