SHORT TERM
(TODAY THROUGH FRIDAY)
ISSUED AT 313 AM EDT THU SEP 3 2026
A HIGH PRESSURE REGIME WILL REMAIN IN PLACE OVER THE SOUTHEAST
THROUGH THE SHORT TERM PERIOD. UPPER LEVEL RIDGING MOVING AWAY TO
THE EAST BEING QUICKLY REPLACED BY A SECOND UPPER RIDGE AMPLIFYING
OVER THE CENTRAL CONUS. WARMER THAN NORMAL TEMPERATURES WILL
CONTINUE, WITH HIGH TEMPERATURES THIS AFTERNOON RISING INTO THE MID
TO UPPER 90S IN ALL BUT THE FAR NORTHEASTERN MOUNTAINS. WITH
DEWPOINTS ALSO REMAINING IN THE UPPER 60S TO LOW 70S, HEAT INDEX
VALUES WILL PEAK IN THE LOW TO MID 100S THIS AFTERNOON. IN ADDITION
TO TEMPERATURES BETWEEN 12-15 DEGREES ABOVE DAILY NORMALS, PORTIONS
OF NORTHWEST GEORGIA WILL ALSO SEE HEAT INDICES CLIMB TO AS HIGH AS
106 DEGREES. BECAUSE OF THIS, A HEAT ADVISORY REMAINS IN EFFECT FOR
FAR THE FAR NORTHWEST CORNER OF THE STATE UNTIL 8 PM EDT THIS
EVENING.
SURFACE HIGH PRESSURE UNDER THE RIDGE AND CENTERED TO THE NORTHEAST
OF THE FORECAST AREA WILL BEGIN TO BREAK DOWN TODAY. WITH THE HIGH
WEAKENING, THERE WILL BE A SLIGHT UPTICK IN RAIN CHANCES THIS
AFTERNOON. ISOLATED SHOWERS AND THUNDERSTORMS WILL BE MOST LIKELY IN
PORTIONS OF EAST-CENTRAL GEORGIA AND IN THE MOUNTAINS, BUT CANNOT BE
RULED OUT ACROSS THE FORECAST AREA. MODEL GUIDANCE CONTINUES TO
INDICATE A BAND OF DEEPER MOISTURE ASSOCIATED WITH A FRONTAL
BOUNDARY MOVING NORTHWARD OUT OF THE GULF ON FRIDAY. THE INFLUENCE
OF THE RIDGE WILL KEEP THIS BOUNDARY STALLED ACROSS SOUTH-CENTRAL
GEORGIA, AND CONTINUE TO SUPPRESS CONVECTION IN THE NORTHERN HALF
OF THE FORECAST AREA. HOWEVER, SCATTERED THUNDERSTORMS WILL BE
ABLE TO DEVELOP IN THE VICINITY OF THE BOUNDARY AND SPREAD INTO
CENTRAL GEORGIA, WITH THE HIGHEST CHANCES IN AREAS ALONG AND SOUTH
OF A LINE FROM COLUMBUS TO MACON.
LONG TERM
(FRIDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 313 AM EDT THU SEP 3 2026
THE WEEKEND WILL START OFF WITH A DAY OF TRANSITION, AS THE STUBBORN
MID-LEVEL RIDGE THAT HAS BEEN OVER THE REGION STARTS GETTING KICKED
WESTWARD BY A DEEP TROUGH OVER THE EASTERN US SEABOARD. DESPITE THE
WANING INFLUENCE OF THE RIDGE, TEMPERATURES WILL STILL RISE TO THE
MID 90S, WITH HEAT INDEX VALUES IN THE LOW 100S. ENOUGH INSTABILITY
SHOULD DEVELOP AND BEAT OUT THE SUBSIDENCE OF THE RIDGE TO SUPPORT
ISOLATED TO SCATTERED AFTERNOON SHOWERS AND STORMS ACROSS THE AREA.
ITS STILL VERY LOW CONFIDENCE AT THIS POINT, BUT WITH STRENGTHENING
NORTHERLY FLOW OVER THE AREA, THERE IS POTENTIAL FOR A LINE OF
STRONG TO SEVERE STORMS TO DROP IN FROM THE NORTH DURING THE LATE
EVENING OR OVERNIGHT HOURS.
RAIN AND THUNDERSTORM CHANCES INCREASE EVEN MORE ON SUNDAY, AS A
FRONTAL BOUNDARY PUSHES INTO THE AREA OUT OF THE CAROLINAS, RUNNING
INTO THE WARM AND MOIST AIRMASS (PWATS AROUND 2") IN PLACE OVER
GEORGIA. DEPENDING ON THE TIMING OF THIS FRONTAL PASSAGE, WE COULD
SEE A THREAT FOR STRONG TO SEVERE STORMS. TEMPERATURES WILL LIKELY
REACH INTO THE LOW TO MID 90S, WITH HEAT INDEX VALUES IN THE UPPER
90S TO LOW 100S. DRY AIR WILL START TO FILTER IN BEHIND THE FRONT ON
MONDAY, BUT LINGERING MOISTURE COULD SUPPORT ISOLATED TO SCATTERED
AFTERNOON SHOWERS AND STORMS. WITH THE DRIER AND COOLER AIR, THERE'D
BE A BIT OF RELIEF FROM THE HEAT, WITH HIGHS LIKELY TOPPING OUT IN
THE MID TO UPPER 80S. UNFORTUNATELY, THIS RELIEF LOOKS SHORT-LIVED,
AS MODEL GUIDANCE IS IN DECENT AGREEMENT ON THE RIDGE BUILDING BACK
ACROSS THE SOUTHEAST BY THE MIDDLE OF NEXT WEEK, WITH HIGHS
RETURNING INTO THE 90S, AND GENERALLY LOW RAIN CHANCES.
AVIATION
(06Z TAFS)
ISSUED AT 135 AM EDT THU SEP 3 2026
VFR CONDITIONS ARE EXPECTED TO PERSIST AT ALL TAF SITES THROUGH
THE PERIOD. PATCHY FOG AND LOW CLOUDS WILL BE POSSIBLE IN
PORTIONS OF EAST-CENTRAL GEORGIA EARLY THIS MORNING, BUT ARE
EXPECTED TO REMAIN SOUTHEAST OF MCN. A SCATTERED CU FIELD BETWEEN
040-060 WILL DEVELOP ONCE AGAIN THIS AFTERNOON UNDERNEATH PASSING
CIRRUS. AN ISOLATED STORM CANNOT BE RULED OUT THIS AFTERNOON, BUT
CHANCES ARE TOO LOW TO WARRANT TAF MENTION AT THIS TIME. WINDS
WILL BE LIGHT AND VARIABLE TO START THE MORNING, BECOMING E/SE AT
5-10 KTS BY 15Z AND THROUGH THE AFTERNOON.
//ATL CONFIDENCE...06Z UPDATE...
