SHORT TERM
(THIS EVENING THROUGH TUESDAY)
ISSUED AT 328 PM EDT MON SEP 28 2026
DEEP NORTHWESTERLY FLOW CONTINUES TO OVERSPREAD GEORGIA AND MUCH OF
THE SOUTHEAST ON THE BACK SIDE OF A NOR'EASTER AND AHEAD OF RIDGE
BUILDING FROM THE SOUTHERN GREAT PLAINS TOWARDS THE NORTHERN GREAT
LAKES. THIS NORTHWESTERLY FLOW CONTINUES TO USHER DRY CONTINENTAL
AIR INTO THE FORECAST AREA. THE DRY AIRMASS AND A BROAD SURFACE HIGH
PRESSURE ASSOCIATED WITH THE RIDGE WILL CONTINUE TO INHIBIT
PRECIPITATION CHANCES AND ALSO AID IN THE DIURNAL MIXING OF VERY DRY
AIR, LEADING TO DEWPOINTS LARGELY IN THE 40S. TEMPERATURES THIS
AFTERNOON WILL LARGELY BE IN THE LOW 80S, WITH MID 80S EXPECTED IN
PORTIONS OF CENTRAL GEORGIA. MINIMUM RH VALUES THIS AFTERNOON ARE
LARGELY EXPECTED TO RANGE FROM 25-30%, THOUGH LOCATIONS IN THE
SOUTHERN TIER COULD BRIEFLY DROP BELOW 25% FOR AN HOUR OR TWO DURING
THE PEAK HEATING HOURS.
ON TUESDAY, THE NOR'EASTER WILL CONTINUE, WELL, NORTHEAST TOWARDS
NOVA SCOTIA WHILE THE AFOREMENTIONED RIDGE AMPLIFIES AND MOVES OVER
THE EASTERN CONUS. AFTER ANOTHER CRISP MORNING WITH LOWS IN THE 50S,
T THE INFLUENCE OF THE RIDGE AND MOSTLY CLEAR AND SUNNY SKIES WILL
LEAD TO TEMPERATURES RISING INTO THE MID 80S ACROSS THE MAJORITY OF
NORTH GEORGIA AND UPPER 80S TO LOW 90S IN CENTRAL GEORGIA. THESE
HIGHS WILL BE ABOUT 5-8 DEGREES ABOVE DAILY NORMALS. ON TUESDAY
AFTERNOON, THE SURFACE HIGH ASSOCIATED WITH THE RIDGE WILL MOVE
OFFSHORE OF THE EASTERN ATLANTIC COAST. SOUTHEASTERLY FLOW AROUND
THE HIGH WILL BEGIN TO GRADUALLY ADVECT ATLANTIC MOISTURE INTO EAST-
CENTRAL GEORGIA. RECOVERY WILL BE SLOW AT FIRST, WITH DEWPOINTS
REMAINING IN THE MID 40S TO LOW 50S ACROSS ALL BUT EAST-CENTRAL
GEORGIA IN THE AFTERNOON. RH VALUES WILL ONCE AGAIN NEED TO BE
MONITORED FOR THE POTENTIAL DEVELOPMENT OF FIRE DANGER CONDITIONS.
THE MOIST SOUTHEASTERLY FLOW WILL PERSIST DURING THE EVENING AND
OVERNIGHT, WITH DEWPOINTS RETURNING TO THE 60S IN AREAS SOUTH OF I-
85 BY THE TIME THE LONG TERM PERIOD PICKS UP.
LONG TERM
(WEDNESDAY MORNING THROUGH NEXT SUNDAY)
ISSUED AT 328 PM EDT MON SEP 28 2026
TEMPERATURES IN THE UPPER 80S AND LOWER 90S ARE EXPECTED FOR MUCH OF
THE CWA AS THE HIGH PRESSURE BEGINS TO BREAK DOWN AND WINDS BECOME
MORE SOUTHERLY IN THE SECOND HALF OF THE WEEK.
AS WE APPROACH THE WEEKEND, THE RIDGE WILL BEGIN TO BREAK DOWN AND
SOUTHERLY FLOW WILL BEGIN TO PULL MOISTURE BACK INTO THE CWA. THIS
WILL BRING CHANCES FOR THUNDERSTORMS BACK UP TO BETWEEN 25-35%
DURING THE AFTERNOON ON FRIDAY WITH MORE WIDESPREAD THUNDERSTORMS
LIKELY THROUGH THE WEEKEND. TEMPERATURES SHOULD REMAIN MODERATED TO
THE UPPER 80S AND LOWER 90S, THOUGH THAT STILL HAS THEM RUNNING 5-10
DEGREES ABOVE NORMAL FOR THIS TIME OF YEAR.
WE'LL NEED TO KEEP AN EYE ON SUNDAY, AS THE BEST DYNAMICS MOVE
THROUGH THE AREA FOR STRONGER THUNDERSTORMS. THE ECMWF BUILDS IN
PLENTY OF INSTABILITY AND DECENT LOW LEVEL SHEAR, THOUGH THE GFS
TENDS TO KEEP A MAJORITY OF THE BULK SHEAR OFF TO THE NORTH.
