...2012 CLIMATE YEAR IN REVIEW...

PERSISTENTLY ABOVE NORMAL TEMPERATURES FROM JANUARY THROUGH JULY... 
HURRICANE SANDY'S CLOSE BRUSH BY THE CAROLINAS IN OCTOBER...AND 
PERIODIC MODERATE TO SEVERE DROUGHT MAINLY ACROSS SOUTH CAROLINA 
WERE THE BIG WEATHER STORIES FOR 2012. 

IN CONTRAST TO THE VERY COLD 2009-2010 AND 2010-2011 WINTERS...THE 
2011-2012 WINTER HAD CONSISTENTLY ABOVE NORMAL TEMPERATURES. THE 
COLDEST TEMPERATURES OF THE WINTER OCCURRED ON THE MORNING OF 
JANUARY 4TH WHEN LOWS DIPPED INTO THE UPPER TEENS INLAND TO AROUND 
20 AT THE COAST. THE COLD FRONT THAT BROUGHT THESE COLD
TEMPERATURES ACTUALLY PRODUCED A TRACE OF SNOW ACROSS SOUTHEASTERN 
NORTH CAROLINA DURING THE EARLY MORNING OF JANUARY 3RD...THE ONLY
SNOW OF THE YEAR. COMPARED TO NORMAL...WARM CONDITIONS INTENSIFIED 
IN MARCH AS A STRONG RIDGE OF HIGH PRESSURE COVERED THE EASTERN 
UNITED STATES A GOOD PORTION OF THE MONTH. TEMPERATURES FOR MARCH 
AVERAGED 7 TO 9 DEGREES ABOVE NORMAL...MAKING IT THE WARMEST MARCH 
ON RECORD IN FLORENCE AND THE THIRD WARMEST IN WILMINGTON.

ACCOMPANYING THE WARM WINTER WEATHER WAS DROUGHT...PARTICULARLY 
ACROSS SOUTH CAROLINA. SEVERE DROUGHT (D2) CONDITIONS EXISTED NEAR 
THE COAST IN JANUARY...BECOMING EXTREME (D3) IN THE GEORGETOWN AREA 
IN FEBRUARY. BENEFICIAL RAINFALL BEGINNING DURING THE MONTH OF MAY 
HELPED ALLEVIATE DROUGHT CONDITIONS THROUGH THE SUMMER...BUT BY THE 
END OF NOVEMBER MODERATE DROUGHT (D1) HAD AGAIN DEVELOPED ACROSS 
PORTIONS OF THE SOUTH CAROLINA PEE DEE REGION. DROUGHT CONDITIONS 
WERE MUCH MORE SEVERE DURING 2012 ACROSS WESTERN SOUTH CAROLINA AND 
INTO CENTRAL GEORGIA.

THE SPRING/SUMMER SEVERE WEATHER SEASON FEATURED SEVERAL REGIONAL 
OUTBREAKS. SEVERE THUNDERSTORMS DURING THE AFTERNOON OF MARCH 25TH 
DROPPED NICKEL TO GOLF BALL SIZE HAIL MAINLY IN THE CAPE FEAR 
REGION. SEVERE THUNDERSTORMS DEVELOPED ON BOTH APRIL 26TH AND 27TH 
WITH NUMEROUS LARGE HAIL REPORTS ACROSS THE AREA. WIDESPREAD SEVERE 
STORMS ON MAY 15TH AND 16TH PRODUCED LARGE HAIL...HIGH WINDS AND 
FLOODING...AND EVEN SENT A GEORGETOWN SC MAN TO THE HOSPITAL WITH A 
NON-FATAL LIGHTNING STRIKE. MORE SEVERE STORMS ON MAY 22ND AND 23RD 
PRODUCED WIDESPREAD LARGE HAIL INCLUDING REPORTS OF GOLF BALL SIZE 
HAIL ACROSS WESTERN COLUMBUS COUNTY AND NEAR HAMPSTEAD IN PENDER 
COUNTY. ON JULY 1ST SEVERE THUNDERSTORMS PRODUCED WIDESPREAD 
DAMAGING WINDS FROM DARLINGTON AND FLORENCE DOWN TO THE COAST. WIND 
GUSTS AT THE FLORENCE AIRPORT WERE MEASURED AT 69 MPH DURING THIS 
EVENT. 

A PERIOD OF EXTREME HEAT DEVELOPED AT THE END OF JUNE AND CONTINUED 
INTO EARLY JULY...ESTABLISHING MANY DAILY RECORD HIGHS AND DRAWING 
TO WITHIN 1-3 DEGREES OF ALL-TIME RECORD HIGHS. THIS HOT WEATHER 
DEVELOPED IN THE PLAINS STATES UNDER A STRONG RIDGE OF HIGH PRESSURE 
THAT MOVED EAST INTO THE CAROLINAS ON JUNE 29TH. TEMPERATURES 
REACHED 103 IN WILMINGTON AND LUMBERTON...105 IN FLORENCE...AND 106 
IN DARLINGTON AND HARTSVILLE. 

EVEN AFTER THE EXTREME HEAT SUBSIDED...TEMPERATURES REMAINED ABOVE 
NORMAL THROUGHOUT THE MONTH OF JULY. IN WILMINGTON JULY 2012 WAS THE 
HOTTEST SINGLE MONTH RECORDED SINCE TEMPERATURE RECORDS STARTED IN 
1874. WILMINGTON HAD 7 DAYS THIS SUMMER (5 OF THEM IN JULY) WITH 
100+ DEGREE TEMPERATURES. WILMINGTON ALSO HAD FOUR NIGHTS IN JULY 
WITH LOW TEMPERATURES 80 DEGREES OR WARMER...ESTABLISHING A NEW 
RECORD. WILMINGTON ALSO RECORDED A RECORD 56 CONSECUTIVE DAYS THIS 
SUMMER WITH LOW TEMPERATURES 70 DEGREES OR WARMER...LASTING FROM 
JUNE 29TH THROUGH AUGUST 23RD. 

THE CONSISTENTLY ABOVE NORMAL TEMPERATURES RECORDED JANUARY THROUGH 
JULY MORE THAN BALANCED OUT A COOLER LATTER PORTION OF THE YEAR... 
AND 2012'S ANNUAL MEAN TEMPERATURE AT BOTH WILMINGTON AND FLORENCE 
IS IN THE WARMEST 10 PERCENT OF ALL YEARS IN THE HISTORIC CLIMATE 
RECORD.

THE TROPICAL SEASON GOT OFF TO AN EXCEPTIONALLY EARLY START IN 2012 
WITH TROPICAL STORM ALBERTO DEVELOPING OVER THE GULF STREAM JUST OFF 
THE SOUTH CAROLINA COAST ON MAY 18TH. ALBERTO DID NOT AFFECT 
LAND...BUT TROPICAL STORM BERYL DID. BERYL FORMED OFF THE FLORIDA 
EAST COAST ON MAY 26TH AND MADE LANDFALL NEAR JACKSONVILLE FLORIDA 
ON THE 28TH. BERYL WEAKENED TO A DEPRESSION AND MOVED NORTHEASTWARD 
ESSENTIALLY CROSSING OVER MYRTLE BEACH AND WILMINGTON ON HER WAY OUT 
TO SEA ON THE 30TH. RAINFALL UP TO NEARLY 4 INCHES WAS RECORDED IN 
WILMINGTON WITH WIND GUSTS AS HIGH AS 45 MPH. IN OCTOBER...HURRICANE 
SANDY WILL BE REMEMBERED FOR HER EXTRAORDINARY IMPACTS IN NEW JERSEY 
AND NEW YORK...BUT HER IMPACTS LOCALLY WERE LIMITED TO RAINFALL OVER 
THREE INCHES NEAR WILMINGTON WITH WIND GUSTS RECORDED AS HIGH AS 50 
MPH AT WRIGHTSVILLE BEACH ON THE MORNING OF OCTOBER 28TH. 

ON OCTOBER 1ST...FOUR EF0 TORNADOES TOUCHED DOWN NEAR HALLSBORO AND 
BOARDMAN IN COLUMBUS COUNTY...AND NEAR COUNCIL AND CARVERS IN BLADEN 
COUNTY. THERE WERE NO INJURIES AND DAMAGE WAS LIMITED TO TREES... 
POWER LINES AND METAL ROOFS FROM SHEDS. THESE WERE THE ONLY 
CONFIRMED TORNADO TOUCHDOWNS IN OUR AREA OF WARNING RESPONSIBILITY 
DURING 2012.

THE FALL MONTHS OF SEPTEMBER THROUGH NOVEMBER FEATURED BELOW NORMAL 
TEMPERATURES CULMINATING IN A VERY COLD NOVEMBER AVERAGING 3 TO 6 
DEGREES BELOW NORMAL. A WIDESPREAD FREEZE THE MORNING OF NOVEMBER 
9TH ENDED THE GROWING SEASON FOR THE INLAND EASTERN CAROLINAS. AN 
EVEN COLDER AIRMASS ENDED THE GROWING SEASON AT THE COAST ON 
NOVEMBER 25TH. 

TEMPERATURES REBOUNDED TO WELL ABOVE NORMAL LEVELS IN DECEMBER. THE
FIRST HALF OF THE MONTH WAS PRACTICALLY SPRING-LIKE WITH 8 OF THE 
FIRST 10 DAYS OF DECEMBER EXCEEDING 70 DEGREES IN FLORENCE. A RARE 
WINTER SEVERE WEATHER EVENT ON DECEMBER 26TH PRODUCED THUNDERSTORM 
WIND DAMAGE IN KURE BEACH AND IN BLADEN COUNTY NEAR JEROME. A 
STORM SURVEY IN KURE BEACH FOUND DAMAGE INDICATIVE OF 70 MPH 
STRAIGHT LINE WINDS. WIND GUSTS WERE MEASURED AT 63 MPH AT NEARBY 
SOUTHPORT DURING THE SAME STORM. WIDESPREAD 1 TO 2 INCH RAINFALL 
TOTALS ALSO OCCURRED WITH THIS WEATHER SYSTEM.
