OVER THE REGION. DURING THIS PERIOD...TEMPERATURES AT BOTH AUGUSTA

BECOME MORE ZONAL AND SYSTEMS BEGAN MOVING FROM WEST TO EAST. ON THE

AND MOVED NORTHEAST TOWARD THE REGION. THIS PRODUCED A WIDESPREAD 
AREA OF HEAVY RAIN WITH AMOUNTS FROM 2 TO 3 INCHES. THE HEAVY 
RAINFALL PRODUCED FLOODING ON MANY OF THE AREA RIVERS FOR SEVERAL 
DAYS. 

BY THE END OF THE MONTH...THE FIRST WINTER WEATHER EVENT OF THE 
SEASON ARRIVED TO THE REGION. AN AREA OF LOW PRESSURE TRAVELED FROM 
WEST TEXAS EASTWARD ACROSS SOUTHERN LOUISIANA AND OFF THE CAROLINA 
COAST FROM THE 28TH THROUGH THE 30TH. ON THE 29TH...A COLD FRONT 
MOVED SOUTH OF THE REGION ALLOWING COLD CANADIAN HIGH PRESSURE TO 
BUILD SOUTHWARD INTO THE REGION. AS THE SYSTEM APPROACHED ON THE 
29TH...MOISTURE BEGAN TO MOVE INTO THE REGION AND CONTINUED INTO 
THE 30TH. A BAND OF SLEET AND SNOW DEVELOPED ACROSS THE NORTHERN 
MIDLAND COUNTIES OF LANCASTER AND CHESTERFIELD. AMOUNTS FROM 

1 TO 4 INCHES WERE OBSERVED WITH THE HIGHEST AMOUNTS IN THE 
PANHANDLE OF LANCASTER COUNTY. JUST TO THE SOUTH...A ZONE OF 
FREEZING RAIN DEVELOPED AS SURFACE TEMPERATURES COOLED TO BELOW 
FREEZING. THE AREA HIT THE HARDEST BY THE FREEZING RAIN STRETCHED 
FROM NORTHERN NEWBERRY COUNTY EASTWARD ACROSS NORTHERN 
FAIRFIELD...NORTHERN KERSHAW...SOUTHERN LANCASTER...SOUTHERN 
CHESTERFIELD AND NORTHERN LEE COUNTIES. A GLAZE OF FREEZING RAIN 
ONE QUARTER TO ONE HALF INCH THICK COATED TREES...POWERLINES AND 
OBJECTS. THE RAIN CHANGED TO FREEZING RAIN AND THE AMOUNTS 
DIMINISHED FROM NORTH TO SOUTH INTO THE CENTRAL MIDLAND COUNTIES OF 
SALUDA...LEXINGTON...RICHLAND...SUMTER AND CLARENDON TO JUST SOME 
LIGHT GLAZE...LESS THAN ONE QUARTER INCH...ON TREES AND ELEVATED 
SURFACES.
