SHORT TERM
(TODAY THROUGH TUESDAY)
ISSUED AT 251 AM EDT MON AUG 31 2026
AS THE MORNING BEGINS, THE AXIS OF A BROAD UPPER LEVEL RIDGE IS
CENTERED OVER THE MISSISSIPPI RIVER VALLEY. THIS RIDGE WILL CONTINUE
TO SHIFT EASTWARD OVER THE COURSE OF THE SHORT TERM PERIOD, BECOMING
CENTERED OVER THE SOUTHEAST ON TUESDAY. AT THE SURFACE, MOISTURE
ADVECTION CONTINUES AS EASTERLY FLOW BRINGS ATLANTIC AIR INTO THE
FORECAST AREA. THE INFLUENCE OF THE RIDGE WILL BRING LOWER CLOUD
COVERAGE AND INCREASING 1000-500 MB HEIGHTS, AND THUS STEADILY
WARMING DAYTIME TEMPERATURES TO THE AREA. THIS AFTERNOON, HIGH
TEMPERATURES ARE EXPECTED TO RISE INTO THE LOW TO MID 90S ACROSS ALL
BUT THE HIGHER ELEVATIONS OF FAR NORTHEAST GEORGIA. HEAT INDEX
VALUES WILL PEAK IN THE LOW 100S THIS AFTERNOON IN AREAS ALONG AND
SOUTH OF THE I-85 CORRIDOR AND IN THE UPPER 90S TO THE NORTH. HIGHS
ON TUESDAY ARE EXPECTED TO BE A COUPLE OF DEGREES HIGHER AREAWIDE,
LARGELY IN THE MID 90S. WITH DEWPOINTS ALSO IN THE LOW TO MID 70S,
HEAT INDICES ON TUESDAY AFTERNOON ARE FORECAST TO RANGE FROM 100-104
DEGREES IN ALL BUT THE FAR NORTHEAST MOUNTAINS.
SUBSIDENCE OF DRY MID-LEVEL AIR UNDER THE RIDGE WILL ALSO HELP
SUPPRESS DIURNALLY-DRIVEN CONVECTION THROUGH THE SHORT TERM PERIOD.
THE GREATEST LIKELIHOOD FOR ISOLATED THUNDERSTORMS WILL BE IN AREAS
SOUTH AND EAST OF MACON DURING THE LATE AFTERNOON AS THE SEA BREEZE
FROM THE GEORGIA/SOUTH CAROLINA WORKS ITS WAY INLAND, AND ALSO IN
THE HIGHER ELEVATIONS OF FAR NORTHEAST GEORGIA WHERE TOPOGRAPHIC
ENHANCEMENT CAN ASSIST WITH STORM DEVELOPMENT. STORMS TODAY AND
TUESDAY ARE NOT EXPECTED TO BE SEVERE, BUT COULD NONETHELESS PRODUCE
LOCALLY HEAVY RAIN AND GUSTY WINDS.
LONG TERM
(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 251 AM EDT MON AUG 31 2026
TEMPS WILL RETURN TO THE MID 90S BY THE MIDDLE OF THE WEEK WITH
WIDESPREAD TRIPLE DIGIT HEAT INDEX VALUES ALONG AND SOUTH OF I-85. A
HEAT ADVISORY MAY BE NEEDED FOR THE SOUTHERN PORTIONS OF THE CWA ON
THURSDAY AND FRIDAY.
OVERNIGHT LOWS WILL ALSO BE ON THE RISE WITH THE RETURN OF THE MID
70S TO MUCH OF THE AREA. THIS DOESN'T DO MUCH IN PROVIDING RELIEF
FROM THE DAYTIME HEAT; ESPECIALLY FOR VULNERABLE POPULATIONS. LOOK
AFTER EACH OTHER, AND KEEP AN EYE ON PETS AND KIDS. STAY HYDRATED IF
YOU PLAN TO SPEND TIME OUTSIDE.
THUNDERSTORM CHANCES DURING THE AFTERNOON WILL BE DOWN TO LESS THAN
2 0% FOR MUCH OF THE AREA THROUGH THE WEEK. A WEAK FRONT IS EXPECTED
NEXT WEEKEND WHICH WILL BRING POPS UP TO AROUND 30%. KEPT POPS TO
LESS THAN CATEGORICAL DUE TO UNCERTAINTY.
