KEY MESSAGES
- HIGH PRESSURE WILL PROMOTE HOT TEMPERATURES AND SUPPRESS RAIN
CHANCES THROUGH MIDWEEK.
- ABOVE NORMAL TEMPERATURES AND HEAT INDEX VALUES IN THE
TRIPLE DIGITS WILL CONTINUE THROUGHOUT THE WEEK, WITH RAIN
CHANCES RETURNING AFTER WEDNESDAY.
SHORT TERM
(THIS AFTERNOON THROUGH TUESDAY)
ISSUED AT 230 PM EDT MON AUG 31 2026
THE EXPANSIVE UPPER RIDGE OVER THE SOUTH-CENTRAL U.S. WILL CONTINUE
TO BUILD EASTWARD THROUGH TUESDAY. TEMPERATURES WILL NOTCH HIGHER ON
TUESDAY AS A RESULT, BRINGING HIGH TEMPERATURES INTO THE MID 90S FOR
MOST AREAS OUTSIDE OF THE MOUNTAINS. HEAT INDEX VALUES WILL ALSO
PUSH NEAR OR OVER 100 DEGREES FOR MOST OF THESE AREAS AS WELL BY
TUESDAY AFTERNOON, THOUGH SHORT OF HEAT ADVISORY CRITERIA OF 105.
AS FAR AS ANY POTENTIAL FOR RAINFALL IS CONCERNED, IT'LL BE FEW AND
FAR BETWEEN. WHILE A ROGUE SHOWER OR BRIEF THUNDERSTORM CAN'T BE
ENTIRELY RULED OUT THROUGH THIS EVENING, MAINLY IN THE NORTHEAST
GEORGIA MOUNTAINS OR FAR SOUTHEAST COUNTIES, TUESDAY WILL BRING EVEN
LESS POTENTIAL WITH THE VAST MAJORITY OF LOCATIONS REMAINING DRY AS
SUBSIDENCE INCREASES FURTHER.
LONG TERM
(WEDNESDAY MORNING THROUGH NEXT SUNDAY)
ISSUED AT 230 PM EDT MON AUG 31 2026
DRY AND WARM WEATHER THROUGH MID-WEEK:
THE EXPANSIVE MID-LEVEL RIDGE WILL SLIDE EAST ON WEDNESDAY,
CENTERING OVER THE CENTRAL AND SOUTHERN APPALACHIANS. FOR NORTH AND
CENTRAL GA, THIS WILL RESULT IN ANOTHER WARM AND MOSTLY RAIN-FREE
DAY. TROPICAL MOISTURE FROM OVER THE ATLANTIC/FLORIDA WILL START TO
PUSH NORTHWARD INTO THE SOUTHERN SIDE OF THE RIDGE, SO WE CAN'T RULE
OUT SOME AFTERNOON SHOWERS AND STORMS IN FAR SOUTHEAST AREAS. HIGH
TEMPS WILL REMAIN IN THE LOW TO MID 90S, WITH HEAT INDEX VALUES
PEAKING AROUND 100-105.
RAIN/THUNDERSTORM POTENTIAL RETURNS LATE WEEK INTO THE WEEKEND:
UNCERTAINTY IN THE FORECAST JUMPS UP SUBSTANTIALLY FOR THE THU/FRI
TIME PERIOD, AS MODELS HAVE SIGNIFICANT SPREAD IN HOW THE SYNOPTIC
PATTERN EVOLVES. OVER THE PAST 24 HOURS, THERE HAS BEEN AN UPTICK IN
THE NUMBER OF ENSEMBLE MEMBERS THAT HAVE A SHORTWAVE TROUGH AND SLUG
OF TROPICAL MOISTURE SURGING UP ACROSS FLORIDA INTO GEORGIA AND
SQUEEZING OUT THE MID-LEVEL RIDGE. WITH PWAT VALUES OF 2-2.5", THIS
WOULD SUPPORT NUMEROUS TO WIDESPREAD SHOWERS AND STORMS EACH DAY,
BECOMING ISOLATED TO SCATTERED OVER THE WEEKEND AS MOISTURE
DECREASES. ON THE FLIP SIDE, THERE IS STILL A GROUP OF ENSEMBLE
MEMBERS THAT HAVE THE RIDGE HOLDING IN PLACE AND SHUNTING THE
TROPICAL MOISTURE OFF TO THE SOUTHWEST, WHICH WOULD KEEP RAIN
CHANCES VERY LOW OVER OUR AREA. WITH EITHER SOLUTION (AND ANYTHING
IN BETWEEN), TEMPERATURES WILL REMAIN AT OR ABOVE NORMAL THROUGH THE
WEEKEND, WITH HIGHS IN THE UPPER 80S TO LOW 90S. CONFIDENCE IN THE
LATE WEEK / WEEKEND FORECAST WILL CONTINUE TO GROW OVER THE NEXT 24-
48 HOURS, SO STAY TUNED FOR UPDATES!
