SHORT TERM
(TODAY THROUGH MONDAY)
ISSUED AT 343 AM EDT SUN SEP 20 2026
MOSTLY CLEAR SKIES ACROSS THE AREA THIS MORNING ON THE HEALS OF
SOME FAIRLY STRONG STORMS THAT WENT THROUGH THE AREA YESTERDAY
AFTERNOON/EVENING. EXPECTING ANOTHER ROUND OF SHOWERS AND
THUNDERSTORMS TODAY BUT SHOULD BE A LOT LESS COVERAGE AS SLIGHTLY
DRIER AIRMASS BEGINS TO MOVE IN ACROSS THE REGION. WEAK HIGH
PRESSURE WEDGE/RIDGE BUILDING BACK INTO THE AREA WILL ALSO HELP
TO SUPPRESS DIURNALLY DRIVEN CONVECTIVE ACTIVITY. THE CURRENT
GENERAL AND MARGINAL RISK AREAS OF SEVERE STORMS FROM SPC LOOKS
GOOD ACROSS THE REGION THROUGH MONDAY. TEMPS REMAIN THE 90S
THROUGH THE SHORT TERM WITH A COOLING TREND BEGINNING IN THE
EXTENDED PERIODS. MONDAY SHOULD BE VERY SIMILAR TO TODAY WITH
ANOTHER ROUND OF ISOLATED SHOWERS AND THUNDERSTORMS.
LONG TERM
(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 343 AM EDT SUN SEP 20 2026
THE EXTENDED PERIOD FOR NORTH AND CENTRAL GEORGIA REMAINS LARGELY
UNCHANGED WITH THIS FORECAST UPDATE. UNSETTLED WEATHER TO START WITH
A RETURN TO MORE SEASONABLE TEMPERATURES AND LOWER RAIN CHANCES AS
WE HEAD INTO THE LATTER HALF OF THE WEEK. THE FORECAST AREA WILL BE
SITUATED IN A NW FLOW REGIME, SUPPORTING THE POTENTIAL FOR MESOSCALE
CONVECTIVE SYSTEMS (I.E. THUNDERSTORM COMPLEXES) TO PUSH THROUGH
PARTS OF THE TN VALLEY. WHILE PINPOINTING THE ORIGIN AND EVOLUTION
OF THESE SYSTEMS REMAINS UNCERTAIN UNTIL GENERALLY A DAY OR TWO
PRIOR, THE POP FORECAST AND SEVERE POTENTIAL THROUGH WEDNESDAY WILL
NEED TO BE MONITORED. AT THIS TIME, RAIN AND THUNDERSTORM CHANCES
PEAK AGAIN ON TUESDAY AND WEDNESDAY AND LOWER THEREAFTER DUE TO A
PATTERN CHANGE. THUS, KEEP AN EYE ON THE FORECAST FOR THOSE WITH ANY
OUTDOOR PLANS EARLY TO MID-WEEK.
ENSEMBLES CONTINUE TO FAVOR A COLD AIR DAMMING WEDGE SETTING UP TO
THE NORTHEAST WEDNESDAY NIGHT LASTING THROUGH THE END OF THE WORK
WEEK. RAIN CHANGES THURSDAY HEADING INTO THE WEEKEND WILL BE MUCH
MORE LIMITED AS SOME DRIER AIR WORKS ITS WAY INTO THE REGION.
ADDITIONALLY, FORECAST HIGH TEMPERATURES IN THE 80S (70S IN THE
MOUNTAINS) AND LOW TEMPERATURES IN THE 50S TO 60S) WILL FINALLY GIVE
US A TASTE OF FALL.
