SHORT TERM
(TODAY THROUGH WEDNESDAY)
ISSUED AT 300 AM EDT TUE AUG 25 2026
TODAY'S FORECAST WILL BE VERY SIMILAR TO THAT OF YESTERDAY. RAIN
AND THUNDERSTORM CHANCES WILL BE LIMITED TO PARTS OF SOUTH-CENTRAL
GEORGIA THIS AFTERNOON -- COLUMBUS TO MACON SOUTHWARD -- DUE TO A
SURFACE LOW SKIRTING NE INTO SOUTH CAROLINA AND GIVING A WEAK
FRONTAL BOUNDARY A SLIGHT NORTHWARD NUDGE. SOUTH OF THIS BOUNDARY,
PLENTIFUL MOISTURE AND INSTABILITY WILL SUPPORT WATER-LOADED
DOWNDRAFT WITH ANY PULSE STORMS, THUS STRONG GUSTY WINDS WILL BE A
POTENTIAL THREAT. AREAS FURTHER NORTH WILL REMAIN DRY AS HIGH
PRESSURE ACROSS THE OHIO AND TN VALLEY REGIONS REMAIN IN PLACE. NW
FLOW ALOFT WILL ALLOW FOR SUFFICIENT MIXING AGAIN TODAY RESULTING
IN COMFORTABLE DAYTIME TEMPERATURES ESPECIALLY ACROSS MUCH OF
NORTH GEORGIA. FORECAST HIGHS IN THE 90S (5-10 DEG COOLER IN THE
MOUNTAINS) COUPLED WITH RELATIVE HUMIDITY IN THE 30-40% RANGE
ACROSS MUCH OF NORTH GEORGIA WILL MAKE IT FEEL QUITE PLEASANT.
SURFACE HIGH PRESSURE WILL BEGIN SHIFTING EASTWARD ON WEDNESDAY
AND MOISTURE STARTS TO RETURN THANKS TO INCREASING SOUTHERLY FLOW.
THUS, RAIN AND THUNDERSTORM CHANCES BECOME MORE DIURNALLY DRIVEN
AND SPREAD FURTHER NORTHWARD. TEMPERATURES WILL ONCE AGAIN CLIMB
BACK INTO THE 90S BUT DEWPOINTS WILL BEGIN A SLIGHT UPWARD TREND.
LONG TERM
(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 300 AM EDT TUE AUG 25 2026
NOT MUCH CHANGE IN THE EXTENDED PERIODS. THE MODELS ARE GENERALLY
IN GOOD AGREEMENT THROUGH THE WEEKEND. TROUGHING OVER THE
SOUTHEAST FOR THE END OF THE WORK WEEK WITH RIDGING BUILDING INTO
THE WEEKEND.
BEGINNING WED AFTERNOON/EVENING, UNDER THE INFLUENCE OF THE
TROUGH, CHANCE TO LIKELY POPS WILL PREVAIL ACROSS THE AREA THROUGH
FRIDAY. A FEW WAVES WITHIN THE TROUGH MAY DIURNALLY ENHANCE
CONVECTION EACH AFTERNOON AND LEAD TO THE POTENTIAL FOR SOME
ISOLATED STRONG TO SEVERE STORMS. THE MODELS ARE SHOWING A
BOUNDARY DEVELOPING OVER GA WED NIGHT/THU MORNING AS A FIRST MAIN
WAVE MOVES SE OUT OF THE MID MS RIVER VALLEY AND INTO W GA. THIS
BOUNDARY STAYS NEARLY STATIONARY THROUGH FRIDAY SO WE COULD SEE A
FAIRLY ACTIVE THU/FRI. PRECIPITABLE WATER VALUES NEAR THE BOUNDARY
STAY AROUND THE 2" RANGE BEGINNING LATE WED THROUGH SAT. THIS IS
MOST LIKELY WHY WPC HAS PLACED A GOOD PORTIONS OF THE STATE UNDER
A MARGINAL RISK OF EXCESSIVE RAINFALL FOR DAYS 4 AND 5. WOULD NOT
BE SURPRISED IF SPC PUT US UNDER A MARGINAL RISK FOR SEVERE STORMS
AS WE GET CLOSER TO THU/FRI. WILL NEED TO SEE HOW THE MODELS
HANDLE THINGS OVER THE NEXT FEW RUNS TO KEEP AND EYE ON
SEVERE/EXCESSIVE RAIN TRENDS.
MOISTURE IS FORECASTED TO REMAIN PLENTIFUL THROUGH THE WEEKEND,
BUT THE BERMUDA RIDGE IS EXPECTED TO BEGIN TO PUSH BACK IN ACROSS
THE SERN U.S. THIS SHOULD HELP TO CAP THE STRONGER TO SEVERE
GROWTH ASPECT OF DIURNAL CONVECTIVE DEVELOPMENT SAT/SUN.
