SHORT TERM
(TODAY THROUGH THURSDAY)
ISSUED AT 144 AM EDT WED SEP 9 2026
A MID-LEVEL RIDGE WILL SLIDE OVER THE SOUTHEAST TODAY, WHICH WILL
KEEP MOST OF THE AREA WARM AND RAIN-FREE. THERE WILL BE A STRONG
MOISTURE GRADIENT STARTING TO DEVELOP ACROSS THE AREA TODAY, WITH
LINGERING DRY AIR IN NORTH GA, AND MOISTURE PUSHING INTO CENTRAL
GA THE SOUTHEAST. BY THIS AFTERNOON, SURFACE DEWPOINTS WILL BE
IN THE LOW TO MID 60S IN NORTH GA, WITH PWAT VALUES AROUND 1".
MEANWHILE, IN CENTRAL GA, DEWPOINTS WILL BE IN THE LOW TO MID 70S
WITH PWAT VALUES NEAR 2". THIS AMOUNT OF MOISTURE COULD SUPPORT
ISOLATED AFTERNOON SHOWERS AND WEAK STORMS, PRIMARILY FOR AREAS
SOUTH AND EAST OF MACON. TEMPERATURES WILL WARM TO THE LOW 90S
ACROSS THE AREA, WITH HIGHER HEAT INDEX VALUES IN THE UPPER 90S TO
NEAR 100 IN CENTRAL GA WHERE THE HIGHER DEWPOINTS ARE.
ON THURSDAY, THE MID-LEVEL RIDGE WILL SLIDE OFF THE EAST, WITH
WINDS OVER THE AREA TURNING OUT OF THE SOUTH. THESE SOUTHERLY
WINDS WILL PUSH THE MOISTURE FURTHER NORTH, RESULTING IN ISOLATED
TO SCATTERED AFTERNOON SHOWERS AND STORMS AS FAR NORTH AS THE I-20
CORRIDOR. HIGH TEMPERATURES WILL AGAIN BE IN THE LOW TO MID 90S,
WITH HEAT INDEX VALUES IN THE UPPER 90S TO LOW 100S ACROSS MOST OF
THE AREA.
LONG TERM
(FRIDAY THROUGH TUESDAY)
ISSUED AT 144 AM EDT WED SEP 9 2026
THE SYNOPTIC PATTERN OVER THE AREA WILL START TO SHIFT ON FRIDAY,
AS THE FLOW TURNS OUT OF THE SOUTHWEST WITH A RIDGE OFF TO THE
EAST, AND TROUGHING FROM THE OH VALLEY DOWN TO THE LOWER MS
VALLEY. MOISTURE WILL BEGIN TO ADVECT UP ACROSS THE AREA FROM THE
GULF ON FRIDAY, SUPPORTING SCATTERED TO NUMEROUS SHOWERS AND
STORMS. HIGH TEMPERATURES IN THE LOW TO MID 90S AND DEWPOINTS IN
THE LOW TO MID 70S WILL DRIVE PEAK HEAT INDEX VALUES INTO THE
100-105 RANGE ACROSS THE AREA. BY SATURDAY, HIGHER MOISTURE
CONTENT (PWATS OF 2-2.2") WILL SPREAD ACROSS THE ENTIRE AREA, WITH
ENHANCED FORCING FROM A TROUGH OVER THE TN VALLEY SUPPORTING MORE
WIDESPREAD SHOWERS AND STORMS. WHILE A FEW STORMS FRIDAY AND
SATURDAY COULD BE STRONG WITH GUSTY WINDS, WE COULD ALSO SEE A
THREAT FOR LOCALIZED FLASH FLOODING FOR ANY AREAS THAT ARE HIT
WITH REPEATED ROUNDS OF STORMS. CLOUD COVER MAY LIMIT HOW WARM
TEMPERATURES GET ON SATURDAY, BUT GENERALLY EXPECTING HIGHS TO
REACH THE LOW 90S, WITH HEAT INDEX VALUES IN THE UPPER 90S TO LOW
100S.
FROM SUNDAY THROUGH EARLY NEXT WEEK, MODELS ARE IN GENERALLY GOOD
AGREEMENT ON THE MID-LEVEL RIDGE OVER THE ATLANTIC RETROGRADING
BACK WEST OVER OUR AREA. MOISTURE CONTENT LOOKS TO REMAIN ABOVE
NORMAL (PWATS OF 1.75-2"), BUT THE INFLUENCE OF THE RIDGE WOULD
KEEP SHOWER AND THUNDERSTORM COVERAGE ISOLATED TO SCATTERED.
TEMPERATURES AND HEAT INDEX VALUES WOULD REMAIN QUITE A BIT ABOVE
NORMAL FOR THIS TIME OF YEAR, WITH HIGHS IN THE LOW TO MID 90S
AND HEAT INDEX VALUES IN THE UPPER 90S TO LOW 100S. AT SOME POINT
'FALL-LIKE' WEATHER WILL FINALLY ARRIVE, BUT ITS VERY UNLIKELY
FOR THE NEXT 7-10 DAYS.
