SHORT TERM
(THIS AFTERNOON THROUGH THURSDAY)
ISSUED AT 132 PM EST WED DEC 17 2025
THE RIDGE AXIS THAT HAS KEPT THINGS DRY FOR THE PAST FEW DAYS IS
LOOSING ITS GRIP IN THE STATE AS IT MOVES FURTHER OFF SHORE. THE
NEXT WAVE TO MOVE INTO THE AREA IS DEVELOPING ALONG THE TX/LA GULF
COAST AND IS EXPECTED TO BEGIN MOVING NE THIS EVENING. THIS WAVE
PUSHES INTO WEST GA RIGHT AROUND DAYBREAK AND CONTINUES TO MOVE
NE THROUGH THU NIGHT/FRIDAY MORNING. THE MAIN FRONTAL BOUNDARY
PUSHES SE OUT OF THE UPPER TO MID MS RIVER VALLEY THU EVENING AND
PUSHES THE WAVE OUT OF THE AREA THROUGH DAYBREAK FRI. THIS FRONT
IS ASSOCIATED WITH A LOW PRESSURE CENTER MOVING EAST ACROSS THE
UPPER GREAT LAKE STATES THU/FRI. NOT EXPECTING MUCH IN THE WAY OF
PRECIPITATION AMOUNTS WITH THIS SYSTEM AS MOST LOCATIONS WILL SEE
0.25" TO 0.75" THROUGH FRI MORNING. THERE WILL BE SOME ISOLATED
LOCATIONS THAT SEE NEAR 1" MAINLY ACROSS THE NORTH GA MOUNTAINS
WHERE THEY WILL HAVE THE OROGRAPHIC AFFECT OF UPSLOPING FLOW TO
WORK WITH.
WITH THE INCREASED CLOUD COVER TONIGHT TEMPS ARE ONLY EXPECTED TO
GET DOWN INTO THE 40S. TEMPS LIFT BACK UP INTO THE 60S THU BUT DIP
BACK DOWN INTO THE 30S AND 40S BEHIND THE EXITING FRONTAL SYSTEM
FRI MORNING.
LONG TERM
(FRIDAY MORNING THROUGH NEXT TUESDAY)
ISSUED AT 132 PM EST WED DEC 17 2025
ANY LINGERING RAIN AND CLOUDS WILL QUICKLY CLEAR OUT THROUGH THE DAY
ON FRIDAY AS HIGH PRESSURE BUILDS IN FROM THE WEST IN WAKE OF A COLD
FRONT. HIGH PRESSURE WILL GRADUALLY SHIFT EASTWARD BUT REMAIN THE
PRIMARY INFLUENCER OF THE WEATHER ACROSS NORTH AND CENTRAL GEORGIA
THROUGH SATURDAY. THUS, MOSTLY DRY CONDITIONS WITH A BRIEF REBOUND
IN TEMPERATURES. SATURDAY MORNING IS LIKELY TO BE THE CHILLIEST
MORNING IN THE LONG TERM GIVEN STRONG RADIATIONAL COOLING. FORECAST
MORNING LOWS WILL BE AT OR BELOW FREEZING AND DAYTIME HIGHS ARE
FORECAST TO CLIMB INTO THE UPPER 50S TO MID 60S.
A WEAK SHORTWAVE AND FRONTAL BOUNDARY WILL SWEEP ACROSS THE OHIO/TN
VALLEY REGIONS ON SUNDAY. THERE IS A LOW CHANCE (25% OR LESS) THAT
PORTIONS OF NORTH GA MAY SEE SOME ISOLATED LIGHT RAIN SHOWERS. BUT
THE QUICK MOVEMENT OF THESE FEATURES AND A LACK OF OVERALL MOISTURE,
THE MOST WE'RE LIKELY TO SEE IS AN INCREASE IN CLOUDS ON SUNDAY.
BETWEEN MONDAY AND TUESDAY, HIGH PRESSURE SETTLES TO THE NORTHEAST
LIKELY RESULTING IN A WEAK CAD WEDGE AND MORE SEASONAL TEMPERATURES
TO KICK OFF THE WORK WEEK. THERE ARE STILL GOOD INDICATIONS AMONG
GLOBAL ENSEMBLES THAT A BROAD SUBTROPICAL RIDGE SETS UP AND
STRENGTHENS ACROSS MOST OF THE SOUTHERN AND CENTRAL US AND STICKS
AROUND FOR A GOOD PORTIONS OF NEXT WEEK. MEANING THERE IS A HIGH
LIKELIHOOD OF SEEING ABOVE-NORMAL TEMPERATURES HEADING INTO THE
CHRISTMAS HOLIDAY.
