NO MAJOR CHANGES MADE TO THE EXTENDED FORECAST. LONG TERM
FORECAST FOCUS CONTINUES TO BE ON SEVERAL PRECIPITATION
EVENTS...THE FIRST BEING SUNDAY INTO MONDAY. EXTENDED MODELS
CONTINUE TO DELAY THE ONSET OF THE PRECIPITATION SUNDAY
MORNING...SO HAVE RAMPED UP POPS A LITTLE MORE SLOWLY THAN THE
PREVIOUS FORECAST. BY SUNDAY NIGHT INTO EARLY MONDAY HAVE LIKELY
POPS ACROSS THE AREA. WITH MINIMUM TEMPERATURES DROPPING INTO THE
MID TO LOW 30S ACROSS FAR NORTH GEORGIA MONDAY MORNING...AND
MOISTURE REMAINING ACROSS THE STATE...HAVE CONTINUED WITH MENTION
OF WINTRY PRECIP...ESPECIALLY ON THE BACK SIDE OF THE SYSTEM WITH
THE WRAP AROUND MOISTURE. THOUGH THERE REMAINS DISCREPANCIES
BETWEEN THE MODELS WITH THE ROBUSTNESS OF THE SYSTEM AND THE
MOISTURE AVAILABILITY...HAVE TRENDED TOWARDS THE PREVIOUS
FORECAST. LITTLE TO NO ACCUMULATION IS EXPECTED...BUT IN THE
HIGHER ELEVATIONS HAVE GONE AHEAD WITH ACCUMULATIONS CONSISTENT
WITH A DUSTING /LESS THAN A QUARTER INCH/.

THE SOUTHEAST SEES A BREAK BETWEEN SYSTEMS EARLY NEXT WEEK WITH
ZONAL FLOW RESUMING ACROSS THE AREA. THIS REPRIEVE IS THEN
FOLLOWED BY INCREASING MOISTURE ACROSS THE STATE MID WEEK AS A
DISTURBANCE IN THE NORTHERN GULF OF MEXICO USHERS PRECIPITATION
BACK TO THE AREA. AT THIS TIME MODELS HEAVILY DIFFER ON THE
NORTHERN EXTENT OF THE MOISTURE AND THE TIMING OF ONSET AND
OFFSET. WITH TEMPERATURES DROPPING INTO THE MID TO LOW 30S BOTH
WEDNESDAY MORNING AND THURSDAY MORNING...HAVE GONE WITH A SLIGHT
CHANCE TO A CHANCE OF RAIN OR SNOW IN THE GRIDS FOR A FEW HOURS
EACH MORNING. FOR NOW...THIS WINTRY PRECIP AREA DOES ENCOMPASS THE
ATL METRO AREA AND WILL NEED TO MONITOR THIS MORE CLOSELY AS THIS
EVENT APPROACHES. FOR NOW...DO NOT EXPECT ANY ACCUMULATIONS.
