..NEW 18Z AVIATION DISCUSSION

TEMPERATURES THROUGH THE NEXT SEVERAL DAYS.
- WARM CONDITIONS ARE EXPECTED TO CONTINUE WITH PRECIP CHANCES
RETURNING THIS WEEKEND.
SHORT TERM
(TODAY THROUGH WEDNESDAY)
ISSUED AT 224 AM EDT TUE SEP 15 2026
THE OVERHEAD CORE OF AN ABNORMALLY STRONG MID-LEVEL RIDGE
(APPROACHING 600 DAM, SOME 3 STANDARD DEVIATIONS ABOVE AVERAGE) AND
COLD AIR DAMMING AT THE SURFACE WILL COMPETE AGAINST ONE ANOTHER
REGARDING SENSIBLE WEATHER IMPACTS TODAY AND TOMORROW. STRONG
SUBSIDENCE WILL CONTINUE TO SUPPRESS MEANINGFUL RAIN CHANCES, THOUGH
A COUPLE OF SHOWERS AND THUNDERSTORMS ARE POSSIBLE LATER TODAY,
FILTERING THROUGH OUR BUILDING EASTERLY FLOW. WINDS WILL BE BREEZY
THIS AFTERNOON, AND HIGHS WILL REMAIN SIMILARLY HOT (IN THE 90S
AREAWIDE), JUST A TICK "COOLER" THAN YESTERDAY. INCREASED MIXING
WITHIN THE WEDGE ZONE WILL HELP TAMP DOWN ON DEWPOINTS, PREVENTING
MORE OPPRESSIVE HEAT FROM BEING REALIZED.
FOR WEDNESDAY, BROAD SCALE CHANGES TO OUR PRESIDING FLOW PATTERN
WILL BE MINIMAL TO NEGLIGIBLE, WITH CONDITIONS EXPECTED TO MIRROR
TODAY: HOT, BREEZY, AND DRY FOR MOST. A COMPARATIVELY MUCH DRIER
AIRMASS WILL FILTER IN ON THE EASTERLY WINDS CHARACTERISTIC OF THE
WEDGE AIRMASS (DEWPOINTS IN THE UPPER 50S TO 60S), KEEPING "FEELS
LIKE" TEMPERATURES WITHIN A COUPLE DEGREES OF AIR TEMPERATURES --
ONCE AGAIN IN THE 90S.
LONG TERM
(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 224 AM EDT TUE SEP 15 2026
THE EXTENDED FORECAST FOR NORTH AND CENTRAL GEORGIA REMAINS LARGELY
UNEVENTFUL. SUBSIDENCE ASSOCIATED WITH MID-LEVEL RIDGING AND A
SURFACE HIGH EXTENDING UP THE EAST COAST SHOULD LARGELY SUPPRESS
ANY MEANINGFUL PRECIPITATION FOR MOST THROUGH THURSDAY. GLOBAL
MODELS AND ENSEMBLES SUGGEST RIDGING AT THE MID-LEVELS BEGINS TO
GRADUALLY BREAK DOWN/RETROGRADE LEADING TO EVENTUAL RETURN OF
MOISTURE BY THE WEEKEND INTO EARLY NEXT WEEK. PRECIPITATION
CHANCES REMAIN LOW (30 PERCENT OR LESS) THROUGH SATURDAY, BUT
WE'RE LIKELY TO SEE CHANCES INCREASE SLIGHTLY EARLY NEXT WEEK
(30-40 PERCENT) AS SOUTHERLY FLOW STRENGTHENS. AS FAR AS
TEMPERATURES GO, THE HEAT WILL STICK AROUND WITH US FOR A LITTLE
WHILE LONGER. TEMPERATURES ARE FORECAST TO RISE INTO THE 90S EACH
AFTERNOON (70S/80S IN THE MOUNTAINS) AND FALL TO THE 60S/LOW 70S
EACH NIGHT/EARLY MORNING.

CONFIDENCE IN PLACEMENT AND EXTENT IS NOT HIGH. OTHERWISE, FEW/SCT
CU 4-6 KFT CAN AGAIN BE EXPECTED WEDNESDAY. WINDS WILL REMAIN E
LARGELY 5-10 KTS WITH A FEW GUSTS OVER 15 KTS POSSIBLE THROUGH
THIS EVENING.
