SHORT TERM
(THIS AFTERNOON THROUGH SUNDAY)
ISSUED AT 230 PM EDT SAT AUG 29 2026
A STALLED FRONTAL BOUNDARY REMAINS SITUATED OVER THE CENTRAL GEORGIA
REGION THAT HAS KEPT MANY LOCATIONS UNDER A LOWER CLOUD FIELD
THROUGH THE MORNING. THIS FIELD HAS BEEN SLOW TO MIX OUT THROUGH THE
AFTERNOON. WITH THE ABUNDANT CLOUDS, EXPECT HIGH TEMPERATURES TO TOP
OUT IN THE MID TO UPPER 80S WITH GRADUAL WARMING THROUGH THE SHORT-
TERM PERIOD. SCATTERED DIURNALLY-DRIVEN THUNDERSTORMS ARE EXPECTED
TO CONTINUE TO DEVELOP THIS AFTERNOON, BUT COVERAGE WILL LIKELY
BE SLIGHTLY REDUCED FROM YESTERDAY DUE TO ONGOING CLOUD COVER AND
DRIER MID TO UPPER LEVEL AIR WORKING INTO OUR CWA. WHILE ORGANIZED
SEVERE WEATHER IS NOT EXPECTED TODAY, A FEW STRONGER STORMS WILL
BE POSSIBLE GIVEN AMPLE SBCAPE AREAWIDE AND A TIGHT DCAPE GRADIENT
WITH VALUES ~1200 J/KG OVER NORTH-NORTHWEST GEORGIA.
ADDITIONALLY, STORMS THAT DO FORM WILL HAVE HEAVY RAINFALL
POTENTIAL DUE TO WEAK STEERING FLOW AND A FAVORABLE LOW LEVEL
MOISTURE PROFILE WITH PWATS IN THE 1.5-2.0 INCH RANGE. THE MAIN
THREAT FROM THESE STORMS WILL BE GUSTY MICROBURST WINDS, FREQUENT
LIGHTNING, AND HEAVY RAINFALL.
AS THE UPPER LEVEL TROUGH CONTINUES TO LIFT NORTHWARD, OUR AREA IS
COMING UNDER GREATER INFLUENCE OF A BROAD UPPER-LEVEL RIDGE
CURRENTLY ANCHORED OVER THE SOUTHERN PLAINS. THIS RIDGE WILL
CONTINUE TO BUILD EASTWARD, REDUCING CLOUD COVER AND GRADUALLY
INCREASING OUR HIGH TEMPERATURES OVER THE COMING DAYS WITH SUNDAY
BEING SLIGHTLY WARMER AND DRIER THAN TODAY. WE CAN ALSO EXPECT
DIURNAL CONVECTION TO BECOME LESS PROMINENT IN THE WEEK AHEAD.
LONG TERM
(MONDAY MORNING THROUGH NEXT FRIDAY)
ISSUED AT 230 PM EDT SAT AUG 29 2026
THE FOREMOST HEADLINE OF THE COMING WEEK WILL BE THE BUILDING HEAT
AS AN EXPANSIVE UPPER RIDGE ENVELOPS THE SOUTHEAST. TEMPERATURES
WILL CREEP UPWARD A DEGREE OR TWO FROM MONDAY-WEDNESDAY WITH HIGHS
IN THE MID 90S COMMONPLACE BY MIDWEEK. MAXIMUM HEAT INDEX VALUES
WILL RISE HAND-IN-HAND, LIKELY IN THE 100-105 RANGE FOR MOST AREAS
OUTSIDE OF THE MOUNTAINS. IN ANY EVENT, THERE ARE NO HOPES FOR
NOTICEABLY COOLER AIR IN THE NEAR FUTURE FOR THOSE LOOKING FOR ANY
SIGNS OF AN END TO SUMMER.
AS FAR AS RAIN CHANCES ARE CONCERNED, POPS WILL GENERALLY BE
TRENDING DOWNWARD AS THE RIDGE EXPANDS EASTWARD, LIKELY ON THE ORDER
OF ISOLATED COVERAGE AT BEST THROUGH MIDWEEK. WITH THAT SAID,
SLIGHTLY HIGHER COVERAGE OF DIURNAL CONVECTION IS POSSIBLE ALONG THE
SOUTHERN TIER AS DEEPER MOISTURE CHARACTERIZED BY PWATS 2+" ADVECTS
WESTWARD WITHIN THE EASTERLY FLOW BENEATH THE CORE OF THE RIDGE TO
THE NORTH.
THE FORECAST BY THE END OF THE WEEK WILL THEN DEPEND TO
SOME DEGREE ON THE TRACK/EVOLUTION OF THE REMNANT WAVE OF FORMER
TROPICAL STORM DOLLY AS IT PUSHES WESTWARD TOWARD FLORIDA AND
POTENTIALLY THE GULF. ENSEMBLE SPREAD (AND THEREFORE FORECAST
UNCERTAINTY) IS HIGH AT THIS EXTENDED TIME FRAME REGARDING TRACK OR
ANY FURTHER DEVELOPMENT; HOWEVER, WE'LL CONTINUE TO MONITOR FOR ANY
POTENTIAL OUTCOME THAT COULD INCREASE MOISTURE AND RAINFALL COVERAGE
BY THE END OF FORECAST PERIOD.
