AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
628 AM EDT MON SEP 14 2026
..NEW 12Z AVIATION DISCUSSION
KEY MESSAGES
- AN ISOLATED SHOWER OR THUNDERSTORM IS POSSIBLE ACROSS FAR NORTH
GEORGIA THIS AFTERNOON. MOST WILL REMAIN DRY.
- SURFACE HIGH PRESSURE WILL KEEP TEMPERATURES WARM AND LIMIT
MEANINGFUL RAIN CHANCES (20% OR LESS EACH AFTERNOON) THIS
NEXT WEEK.
SHORT TERM
(TODAY THROUGH TUESDAY)
ISSUED AT 305 AM EDT MON SEP 14 2026
PRESIDING MID-LEVEL RIDGING AND SURFACE HIGH PRESSURE WILL SUPPORT
MOSTLY DRY AND (UNSEASONABLY) WARM CONDITIONS THROUGH TUESDAY. A
COLD FRONT SITUATED ALONG THE SOUTHERN PERIPHERY OF THE
AFOREMENTIONED SURFACE HIGH WILL PROVIDE A GLANCING BLOW TO FAR
NORTH GEORGIA, SUFFICIENT TO SUPPORT AT LEAST AN OFF-CHANCE OF AN
ISOLATED SHOWER OR THUNDERSTORM THIS AFTERNOON.
TOMORROW, HIGH PRESSURE BUILDS ACROSS NEW ENGLAND, SETTING THE
STAGE FOR WEAK, DRY COLD AIR DAMMING. HIRES GUIDANCE SUGGESTS
WE'RE LIKELY TO SEE AN INCREASE IN CLOUD COVER, BUT MINIMAL
SENSIBLE IMPACTS OVERALL. BEST RAIN CHANCES (UP TO 30-40%) WILL
BE CONFINED TO SOUTH AND SOUTHEAST CENTRAL GEORGIA IN THE VICINITY
OF A LOCAL MAXIMUM IN LOW-LEVEL CONVERGENCE/A VERY SMALL SCALE
DISTURBANCE ROUNDING THE BROADER WEDGE ISOBARS. OTHERWISE, ONLY
ISOLATED CONVECTION (AT BEST) IS EXPECTED ALONG THE EDGE OF THE
COOL DOME.
HIGHS WILL REMAIN IN THE 90S FOR ALL BUT FAR NORTHEAST GEORGIA,
JUST A TICK COOLER TOMORROW. HEAT INDEX VALUES WILL RISE INTO THE
UPPER 90S TO LOWER TRIPLE DIGITS FOR MOST.
LONG TERM
(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 305 AM EDT MON SEP 14 2026
WARM CONDITIONS AND OVERALL LOW RAIN CHANCES WILL BE THE RULE
THROUGH THE LONG TERM PERIOD.
GENERALLY SPEAKING, THE UPPER-LEVEL PATTERN WILL BE CHARACTERIZED BY
RIDGING OVER MUCH OF THE SOUTHEAST. A COLD AIR DAMMING (CAD) WEDGE
SETUP WILL BE IN PLACE TUESDAY THROUGH WEDNESDAY, BUT THE RESULTING
EASTERLY FLOW WILL DO LITTLE TO MODERATE TEMPERATURES. THAT SAID, A
DECREASE IN DEWPOINTS IS EXPECTED WEDNESDAY AND THURSDAY -- IN THE
60S COMPARED TO THE 70S ON TUESDAY. THE OVERNIGHT/EARLY MORNING
HOURS DURING THIS TIMEFRAME WILL ALSO BE RELATIVELY COOLER GIVEN THE
SLIGHTLY DRIER AIR.
AT THIS TIME, APPRECIABLE RAIN CHANCES WILL BE HARD TO COME BY UNTIL
FRIDAY AND SATURDAY, WHEN ENSEMBLE GUIDANCE SUGGESTS THAT THE UPPER-
LEVEL RIDGE WILL WEAKEN/RETROGRADE. EVEN THEN, THE GREATEST POPS ARE
AROUND 30% AND ARE CONFINED TO FAR NORTH GEORGIA AND PARTS OF
CENTRAL GEORGIA BOTH DAYS.
