SHORT TERM
(TODAY THROUGH THURSDAY)
ISSUED AT 320 AM EDT WED SEP 2 2026
A HIGH PRESSURE REGIME REMAINS IN PLACE OVER THE SOUTHEAST, WITH THE
AXIS OF A BROAD UPPER RIDGE NEAR THE ALABAMA/GEORGIA STATE LINE AND
EXTENDING NORTHWARD INTO THE LOWER GREAT LAKES REGION AND SURFACE
HIGH PRESSURE CENTERED OVER THE SOUTHERN APPALACHIANS. THE ONGOING
WARMING TREND UNDER THE RIDGE WILL CULMINATE TODAY WITH HIGH
TEMPERATURES RISING INTO THE MID TO UPPER 90S ACROSS THE AREA WITH
THE EXCEPTION OF THE FAR NORTHEASTERN MOUNTAINS. THE WARMEST
TEMPERATURES TODAY ATE EXPECTED IN AREAS NORTH AND WEST OF ATLANTA,
WHICH WILL BE AS MUCH AS 12-15 DEGREES ABOVE DAILY NORMALS COMPARED
TO 6-10 DEGREES ABOVE NORMAL IN CENTRAL GEORGIA. DEWPOINTS WILL ALSO
RANGE FROM THE UPPER 60S TO LOW 70S AS MOIST EASTERLY FLOW STREAMS
INTO THE AREA AROUND THE SURFACE HIGH. HEAT INDEX WILL RISE INTO THE
LOW TO MID 100S THIS AFTERNOON. PORTIONS OF NORTHWEST GEORGIA ARE
FORECAST TO SEE HEAT INDICES AS HIGH AS 107 DEGREES, BECAUSE OF
THIS, A HEAT ADVISORY HAS BEEN ISSUED FOR THIS AREA FROM 1 PM TO 8
PM TODAY.
DRIER AIR UNDER THE RIDGE WILL ALSO HELP SUPPRESS DIURNAL
CONVECTION. THAT SAID, A FEW ISOLATED SHOWERS AND THUNDERSTORMS
CANNOT BE RULED OUT THIS AFTERNOON. THIS POSSIBILITY IS MOST LIKELY
IN SOUTH-CENTRAL GEORGIA FURTHEST FROM THE CENTER OF THE RIDGE AND
IN THE FAR NORTHEASTERN MOUNTAINS WITH INCREASED TOPOGRAPHIC LIFT.
EVEN HERE, POPS ARE NO HIGHER THAN 20% AT THIS TIME. CONDITIONS WILL
BE LARGELY SIMILAR ON THURSDAY, THOUGH THE INFLUENCE OF THE RIDGE
WILL BEGIN TO WEAKEN AS THE AXIS BEGINS TO SHIFT TO THE EAST. HEAT
INDICES IN THE LOW TO MID 100S ARE EXPECTED ONCE AGAIN, AND THE
POTENTIAL FOR HEAT ADVISORY CRITERIA BEING REACHED OR EXCEEDED WILL
NEED TO BE MONITORED ONCE AGAIN. MORE SCATTERED THUNDERSTORMS ARE
FORECAST TO RETURN TO CENTRAL GEORGIA ON THURSDAY AFTERNOON.
LONG TERM
(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 320 AM EDT WED SEP 2 2026
A RIDGE REMAINS IN PLACE OVER THE SOUTHEASTERN UNITED STATES ON
FRIDAY INTO THE WEEKEND. LITTLE CHANGE IN THE TEMPERATURE TRENDS ARE
LIKELY BECAUSE OF THIS. HIGHER THAN AVERAGE TEMPERATURES WILL REMAIN
IN PLACE - WITH TEMPERATURES AROUND 8-13 DEGREES HIGHER THAN
CLIMATOLOGY THROUGH SUNDAY. DAYTIME HIGHS WILL BE IN THE UPPER 80S
TO UPPER 90S, WITH HEAT INDICES FROM AROUND 90 TO 106F.
SUFFICIENT MOISTURE AND INSTABILITY WILL BE IN PLACE TO SUSTAIN
DIURNAL CONVECTION. MOISTURE LEVELS, AND THEREFORE PRECIP CHANCES,
WILL BE GREATER OVER CENTRAL GEORGIA THAN NORTHERN GEORGIA AND THE
ATLANTA METRO, WHERE POPS WILL BE AROUND 20% OR LESS. THE GREATEST
RISK FOR THUNDERSTORMS WILL BE ON SUNDAY, WITH ADDITIONAL MOISTURE
AND INSTABILITY, ASSOCIATED WITH THE ARRIVAL OF A FRONTAL
BOUNDARY.
SLIGHTLY COOLER AIR IS EXPECTED BEHIND THE FRONTAL BOUNDARY ON
MONDAY, AS A RIDGE OF HIGH PRESSURE CENTERED OVER HUDSON BAY SINKS
SOUTHWARD. STILL, DAYTIME HIGHS WILL REMAIN ABOVE CLIMATOLOGY BY
AROUND 5 TO 10 DEGREES, WITH HIGHS IN THE LOW 80S TO MID 90S ACROSS
NORTHERN AND CENTRAL GEORGIA. THOUGH POPS DECREASE SOMEWHAT ON
MONDAY, AND MORESO ON TUESDAY, THERE REMAINS THE POTENTIAL FOR
DIURNAL CONVECTION, WITH ISOLATED TO SCATTERED AFTERNOON/EVENING
THUNDERSTORMS.
