SHORT TERM
(TODAY THROUGH THURSDAY)
ISSUED AT 317 AM EDT WED SEP 23 2026
COLD AIR DAMMING WEDGE (CAD) IS BEGINNING TO PUSH INTO NE GA THIS
MORNING WITH LOW CEILINGS DEVELOPING ACROSS THE AREA. ALSO SEEING
SOLID NE WINDS ACROSS THE CAROLINAS WITH SPEEDS IN THE 5-10MPH
RANGE WITH GUST TO 15MPH. THIS NE FLOW IS DEFINITELY BEGINNING TO
MOVE INTO GA AND WILL PLAY A HUGE ROLE IN WHAT HAPPENS THROUGH
THE SHORT TERM. THIS CAD WEDGE IS EXPECTED TO MOVE INTO NORTH AND
CENTRAL GA TODAY AND CONTINUE BUILDING SW THROUGH TONIGHT. THIS
WILL BRING A COOLER AND MUCH MORE STABLE AIRMASS ACROSS THE STATE
WITH HIGH TEMPS EXPECTED IN THE LOWER TO MIDDLE 70S ACROSS NE GA
TO THE UPPER 80S ACROSS WEST CENTRAL GA. WE WILL STILL SEE SOME
PRECIPITATION ACROSS THE AREA AS THERE IS STILL A DECENT AMOUNT OF
LOW TO MID LEVEL MOISTURE BUT THINGS WILL BE MAINLY DRIZZLE AND
LIGHT SHOWERS. WE WILL SEE A LITTLE BIT OF DIURNALLY DRIVEN
INSTABILITY ACROSS NW GA SO WE COULD SEE AND ISOLATED STRONG
STORM OR TWO.
THIS COOLER AIRMASS CONTINUES TO PUSH IN ACROSS THE STATE TONIGHT
WITH LOWS IN THE UPPER 50S TO MIDDLE 60S. THIS WILL ALSO KEEP
HIGH TEMPS BELOW SEASONAL NORMS THU WITH HIGH MAINLY IN THE UPPER
60S TO NEAR 80. WE WILL STILL SEE MOSTLY CLOUDY SKIES ACROSS THE
AREA THU BUT WITH A SLIGHTLY DRIER AIRMASS NOT EXPECTING MUCH
PRECIP.
LONG TERM
(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 317 AM EDT WED SEP 23 2026
BY THE START OF THE LONG TERM PERIOD ON FRIDAY, THE STAGE WILL BE
SET FOR AN EXTENDED PERIOD OF DRYING NORTHWESTERLY FLOW AT THE MID-
LEVELS -- WITH THE SOUTHEAST SITUATED ON THE EASTERN PERIPHERY OF
STAGNATING RIDGING AND WITHIN A REGIME OF STRONG SUBSIDENCE BEHIND A
DEEPENING COASTAL LOW ACROSS THE EASTERN SEABOARD. AN AIRMASS THAT
ORIGINATED ACROSS EASTERN CANADA WILL BE DRAGGED SOUTHWARD ON THE
BACKSIDE OF THE AFOREMENTIONED LOW, WORKING WITH THE FINAL VESTIGES
OF A STRONG CAD EVENT TO SUPPORT MORE SEASONABLE TEMPERATURES FOR
LATE SEPTEMBER: GENERALLY IN THE MID-70S TO LOWER 80S THROUGH THE
WEEKEND. MODERATION WILL OCCUR AS WE MOVE INTO NEXT WEEK, WITH
AFTERNOON HIGHS RISING BACK INTO THE 80S AREAWIDE. MORNING LOWS WILL
BE CRISP AND POSITIVELY FALL-LIKE (FINALLY), IN THE 50S FOR MOST.
CONTINUED SUBSIDENCE AND A COMPARATIVELY MUCH DRIER AIRMASS WILL
KEEP POPS NEAR-NEGLIGIBLE THROUGH MIDWEEK NEXT WEEK (<15%, WHICH IS
THE DELINEATOR BETWEEN DRY AND MENTION OF ISOLATED RAIN CHANCES).
