QUICKLY IMPROVE THEREAFTER.

OFFSHORE BY THE 4-5PM TIME FRAME. THERE IS STILL A CHANCE FOR THIS
RAINFALL TO END AS A PERIOD OF WET SNOWFALL MIXED IN FOR POINTS TO
THE NORTH AND WEST OF WAYCROSS, GA AND WILL LIKELY LEAVE CURRENT
WINTER WEATHER ADVISORY IN PLACE UNTIL ITS END TIME OF 2PM EST, BUT
CHANCES FOR ANY SIGNIFICANT SNOWFALL ACCUMULATIONS ARE LOW. THE

AT 15-25G30-35 MPH FOR THE REMAINDER OF THE AFTERNOON, BEFORE
DECREASING AFTER SUNSET. TEMPS GENERALLY IN THE MID/UPPER 30S ACROSS
INLAND SE GA AND 40S ELSEWHERE WILL CONTINUE TO SLOWLY FALL THROUGH
THE REST OF THE AFTERNOON.

TOWARDS SUNRISE MONDAY MORNING FOR A WIDESPREAD FROST EVENT OVER ALL-
