CENTRAL ALABAMA TODAY WITH A SURFACE LOW OVER WEST CENTRAL GEORGIA
DEEPENING WHILE MOVING TO NEAR COASTAL SOUTH CAROLINA.  AREA RADARS
CURRENTLY SHOW PATCHY PRECIPITATION WEST AND NORTH OF THE FORECAST

PRECIPITATION IMMEDIATELY WEST AND NORTH OF THE FORECAST AREA IS
STILL IN THE FORM OF LIGHT RAIN BUT HAS SWITCHED OVER TO LIGHT SNOW
AROUND AND WEST OF A MCB...JAN...STF LINE.  THIS IS BOTH A DIFFICULT
POP AND PRECIP TYPE FORECAST THIS MORNING AS TEMPERATURES TREND
SLIGHTLY COOLER DURING THE OVERNIGHT HOURS FOLLOWED BY A PUSH OF
DRIER AIR LATER THIS MORNING INTO THE EARLY AFTERNOON WHICH WILL
BRING AN END TO THE PRECIPITATION.  THE INFLUX OF PROGRESSIVELY

SUPPORTIVE FOR A WINTRY MIX OF PRECIPITATION OVER THE NORTHWESTERN
FOURTH OF THE AREA...THE SWITCH OVER TO A WINTRY MIX IN THE OBSERVED
DATA HAS REMAINED FURTHER WEST AND NORTH AND APPEARS TO BE A RESULT
OF THE DRIER AIR WORKING INTO THE AREA AS WELL AS LOWER LEVEL

FOR A VERY DIFFICULT PRECIP TYPE FORECAST WITH ATMOSPHERIC
CONDITIONS RUNNING RAZOR CLOSE BETWEEN RAIN AND SNOW OVER THE
NORTHWESTERN PORTION AND HAVE GONE WITH A MIX OF LIGHT RAIN AND
LIGHT SNOW THIS MORNING OVER INTERIOR SOUTHEAST MISSISSIPPI AND
INTERIOR SOUTHWEST ALABAMA WITH AN OTHERWISE LIQUID PRECIPITATION
