..AFTERNOON AREA FORECAST DISCUSSION
KEY MESSAGES
- HIGH PRESSURE WILL PROMOTE DRIER CONDITIONS AND WARMING
TEMPERATURES.
- ISOLATED THUNDERSTORMS WILL BE POSSIBLE IN CENTRAL GEORGIA
THIS AFTERNOON AND MONDAY AFTERNOON.
- ABOVE NORMAL TEMPERATURES AND HEAT INDEX VALUES IN THE TRIPLE
DIGITS WILL PERSIST ALONGSIDE MOSTLY DRY CONDITIONS THROUGH THE
END OF THE WEEK.
SHORT TERM
(THIS AFTERNOON THROUGH MONDAY)
ISSUED AT 211 PM EDT SUN AUG 30 2026
AN UPPER-LEVEL RIDGE WILL CONTINUE TO BUILD EASTWARD WITH OUR REGION
ALONG THE EASTERN SIDE OF THE RIDGE AXIS. CONTINUED LOW-LEVEL
MOISTURE ADVECTION ASSOCIATED WITH SOUTHEASTERLY FLOW WILL FUNNEL
HIGHER PRECIPITABLE WATER VALUES INTO OUR CENTRAL AND SOUTHERN CWA.
EVEN WITH THE BUILDING HIGH PRESSURE AND THE GROWING MID TO UPPER-
LEVEL DRY AIR OVERSPREADING OUR AREA, WE CAN EXPECT DIURNAL ISOLATED
TO SCATTERED SHOWER AND THUNDERSTORM CHANCES TO CONTINUE INTO MONDAY
AFTERNOON. HOWEVER, POP CHANCES WILL BE CAPPED AROUND THE 15% RANGE
AND ALIGNED MOSTLY SOUTH OF COLUMBUS TO MACON. A FEW OF THE STORMS
THAT DO DEVELOP TODAY OR TOMORROW WILL HAVE THE POTENTIAL TO BE
STRONG, WITH GUSTY WINDS AND HEAVY RAINFALL BEING THE PRIMARY
THREATS. PRECIPITATION CHANCES WILL BE MORE LIMITED EACH DAY AS OUR
PATTERN CONTINUES TO TRANSITION TO A MORE CONVECTIVELY SUPPRESSED
SUMMERTIME REGIME.
WE WILL ALSO SEE OUR DAYTIME TEMPERATURES BEGAN TO CLIMB INTO THE
UPPER 80S TO LOW 90S OVER THE NEXT COUPLE DAYS WITH LESS CLOUD COVER
AND BUILDING HEIGHTS. THE HIGHER TEMPERATURES COMBINED WITH THE
PREVIOUSLY MENTIONED LOW-LEVEL MOISTURE ADVECTION WILL KEEP
DEWPOINTS IN THE LOW TO MID-70S OVER MOST OF OUR AREA, MAKING IT
FELL UNCOMFORTABLE IN THE AFTERNOONS. AS A RESULT, THE HEAT INDEX
WILL CLIMB INTO THE MID 90 TO LOW 100S THROUGH MONDAY AFTERNOON
EVERYWHERE OUTSIDE OF THE MOUNTAIN COUNTIES. THIS WILL LIKELY FALL
BELOW HEAT ADVISORY CRITERIA, BUT WE WILL NEED TO MONITOR THE
CONDITIONS AS WE MOVE FURTHER INTO NEXT WEEK.
LONG TERM
(TUESDAY MORNING THROUGH NEXT SATURDAY)
ISSUED AT 211 PM EDT SUN AUG 30 2026
THERE ARE NO BIG CHANGES IN EXPECTATIONS FOR THE BULK OF THE
EXTENDED FORECAST PERIOD THAT WILL BRING HOT AND MOSTLY DRY
CONDITIONS WITH ANY HOPE FOR A PATTERN CHANGE DELAYED UNTIL AT LEAST
NEXT WEEKEND. ABOVE NORMAL TEMPERATURES WILL PEAK DURING THE MIDWEEK
TIME FRAME AS THE EXPANSIVE UPPER RIDGE REACHES ITS APEX ACROSS THE
REGION. WIDESPREAD HIGHS IN THE MID 90S AND HEAT INDEX VALUES NEAR
AND OVER 100 DEGREES ARE EXPECTED. THIS WILL ALSO SERVE TO GREATLY
LIMIT RAIN CHANCES FOR THE VAST MAJORITY OF THE AREA WITH ANY
APPRECIABLE CHANCES FOR DIURNAL PRECIPITATION SHUNTED TO THE FAR
SOUTHERN COUNTIES.
AS MENTIONED ABOVE, HINTS OF ANY PATTERN CHANGE WILL HOLD OFF UNTIL
NEXT WEEKEND WHEN THE UPPER RIDGE MAY RETROGRADE WESTWARD,
POTENTIALLY SETTING UP A TROUGH ACROSS THE EASTERN U.S. AND ALLOWING
A FRONTAL BOUNDARY TO PUSH TOWARD THE AREA. THIS WILL ALSO HAVE A
HAND IN DETERMINING THE EVENTUAL TRACK/EVOLUTION OF THE WAVE
ASSOCIATED WITH THE REMNANTS OF FORMER T.S. DOLLY AND ITS ASSOCIATED
MOISTURE. GIVEN THIS REMAINS A WEEK AWAY, THERE IS PLENTY OF
UNCERTAINTY IN FORECAST DETAILS, SO AT THIS JUNCTURE POPS GRADUALLY
INCREASE BY NEXT WEEKEND.
AVIATION
(18Z TAFS)
ISSUED AT 128 PM EDT SUN AUG 30 2026
CEILINGS CONTINUE TO LIFT TO THE PREVAILING LOW-VFR/VFR RANGE
WITH SOME PATCHY MVFR IMPROVING THROUGH 20Z. THE CU FIELD WILL BE
SCATTERED TO BROKEN THROUGH THE AFTERNOON PRODUCING A FEW ISOLATED
SHOWERS AND THUNDERSTORMS THROUGH SUNSET. SURFACE WINDS WILL BE
LIGHT, FAVORING THE NORTHEAST TO SOUTHEAST AROUND 6KTS BECOMING
LIGHT AND VARIABLE OVERNIGHT. EXPECT A FEW SITES WITH MVFR/IFR
CEILINGS POSSIBLE SOUTH OF COLUMBUS TO MACON BY DAYBREAK
TOMORROW.
//ATL CONFIDENCE...18Z UPDATE...
