As an upper level short wave trough approached the area from the west, reports of sleet began across portions of north and central Florida after midnight and continued through the late morning hours.

...RAIN TURNING TO SNOW ACROSS SOUTHEAST GA FRIDAY AFTERNOON...
.UPDATE...
REGIONAL SOUNDINGS REVEAL A VERY DRY AIRMASS FROM THE SURFACE TO 10K
FEET...BENEATH A DEEPENING CLOUD LAYER. RADIATIONAL COOLING HAS THUS
BEEN FAIRLY WEAK. OVERNIGHT LOWS WILL BE MAINLY DEPENDENT ON
EVAPORATIONAL COOLING WHICH NOW APPEARS THE BULK OF WILL HOLD OFF
UNTIL AFTER SUNRISE...WHEN PRECIP FINALLY STARTS TO REACH THE
GROUND. THIS WILL RESULT IN TEMPS FALLING AFTER SUNRISE DUE TO THE
EVAPORATIONAL COOLING AFFECTS. WITH THIS IN MIND...DECIDED TO
RAISE TEMPS A FEW DEGREES OVERNIGHT WITH LOWS GENERALLY IN THE MID
TO UPPER 30S ACROSS THE BOARD. ALSO LOWERED POPS BY ABOUT 10
PERCENT DUE TO THE AMOUNT OF LOW LEVEL DRY AIR IN PLACE.
JUST NOW GETTING A BRIEF GLIMPSE OF THE 0Z NAM RUN AND A
CHANGEOVER TO SNOW ACROSS PORTIONS OF SOUTHEAST GEORGIA IS LOOKING
VERY LIKELY FRIDAY AFTERNOON. AROUND AN INCH OF HEAVY WET SNOW
WILL BE POSSIBLE ACROSS OUR NORTHERN COUNTIES...POSSIBLY 2
INCHES. WILL LET THE MIDNIGHT SHIFT FURTHER EVALUATE ALL THE DATA
BEFORE MAKING A FINAL DECISION ON A WINTER STORM WARNING. IF THE
0Z GFS RUN COMES IN SIMILAR TO THE NAM THEN A WARNING WILL BE
LIKELY. THIS IS A VERY DYNAMICAL SYSTEM AND ACCUMULATING SNOW
ACROSS SOUTHEAST GEORGIA IS NOT UNREASONABLE. PLEASE CONTINUE TO
CLOSELY FOLLOW THE WINTER STORM PRODUCTS AND THE WINTER WEATHER
