..AFTERNOON AREA FORECAST DISCUSSION
KEY MESSAGES
- A COOLER AIRMASS WILL REMAIN IN PLACE THROUGH THE WEEKEND

- MOSTLY DRY CONDITIONS EXPECTED THROUGH THE MIDDLE OF NEXT
WEEK.
- WARMING TREND BACK TO ABOVE NORMAL TEMPERATURES EARLY NEXT
WEEK.
SHORT TERM
(THIS AFTERNOON THROUGH SATURDAY)
ISSUED AT 231 PM EDT FRI SEP 25 2026
A COOLER AIRMASS WILL CONTINUE TO FILTER IN OVER THE CWA THANKS
TO A STRONG DEVELOPING COASTAL LOW THAT WILL START TO MOVE ALONG
THE EASTERN SEABOARD OVER THE SHORT TERM. THIS DEVELOPING SYSTEM,
IN COMBINATION WITH INLAND HIGH PRESSURE STATIONED OVER THE GREAT
LAKES REGION, WILL SUPPORT COOL AND DRY CONDITIONS INTO THE
WEEKEND. AS A RESULT, EXPECT DEW POINT TEMPERATURES DOWN INTO THE
40S OVER THE AREA ON SATURDAY, CONTINUING THE 'FALL-LIKE' FEEL IN
THE AIR. DAYTIME HIGHS WILL TOP OUT IN THE MID TO UPPER 70S TODAY
AND SLIGHTLY WARMER FOR SATURDAY AFTERNOON. OVERNIGHT TEMPERATURES
WILL BE CRISP AREA-WIDE, DROPPING INTO THE LOW TO MID-50S ON
SATURDAY MORNING AT MOST LOCATIONS. IN ADDITION TO THE COOLER
CONDITIONS, EXPECT SKIES TO IMPROVE THROUGH THE DAY FRIDAY, WITH
PARTLY CLOUDY TO CLEAR CONDITIONS EXPECTED THIS AFTERNOON AND
THROUGH TOMORROW. ALONG WITH THIS DRY PATTERN, THERE IS NO CHANCE
OF PRECIPITATION IN THE SHORT TERM WITH TRANQUIL CONDITIONS
EXPECTED.
LONG TERM
(SUNDAY MORNING THROUGH NEXT THURSDAY)
ISSUED AT 231 PM EDT FRI SEP 25 2026
THE LONG TERM PERIOD WILL BEGIN WITH A VERTICALLY STACKED LOW
PRESSURE SYSTEM LINGERING NEAR THE NEW ENGLAND COAST AND A HIGH
PRESSIE MID-LEVEL RIDGE EXTENDING THROUGH THE CENTRAL CONUS.
NORTH AND CENTRAL GEORGIA WILL BE POSITIONED UNDERNEATH
NORTHWESTERLY FLOW BETWEEN THESE TWO FEATURES, WHICH WILL CONTINUE
TO BRING DRY, CANADIAN CONTINENTAL AIR INTO THE REGION. THIS DRY
AIR, WHICH WILL LIMIT DEWPOINTS TO THE 40S AND LOW 50S AND
PRECIPITABLE WATER VALUES TO 0.4-0.7 INCHES, COMBINED WITH
SUBSIDENCE UNDERNEATH LINGERING SURFACE HIGH PRESSURE WILL INHIBIT
RAIN CHANCES THROUGH AT LEAST MID- WEEK. ON MONDAY AND TUESDAY,
THE LOW PRESSURE SYSTEM WILL GRADUALLY WEAKEN AND MOVE AWAY TO THE
NORTHEAST AS THE RIDGE ADVANCES EASTWARD. HIGH TEMPERATURES ON
SUNDAY WILL BE NEAR TO JUST ABOVE CLIMATOLOGICAL NORMALS, IN THE
MID 70S TO LOW 80S IN NORTH GEORGIA AND LOW TO MID 80S IN CENTRAL
GEORGIA. VERY DRY AIR WILL REMAIN UNDER THE RIDGE, THOUGH THE
AIRMASS WILL MODERATE AND TEMPERATURES WILL STEADILY CLIMB EACH
DAY. LOW TEMPERATURES ON MONDAY AND TUESDAY WILL REMAIN BRISK AND
SEASONABLE, IN THE UPPER 40S IN FAR NORTHEAST GEORGIA AND 50S
ELSEWHERE ACROSS THE AREA. IN CONTRAST, HIGHS BY TUESDAY AFTERNOON
WILL BE IN THE MID TO UPPER 80S ACROSS THE MAJORITY OF NORTH
GEORGIA AND LOW 90S IN CENTRAL GEORGIA, WHICH WILL BE ABOUT 6-10
DEGREES ABOVE CLIMATOLOGICAL NORMALS. WITH SEVERAL DAYS OF DRY
WEATHER AND SUNNY SKIES, MINIMUM RELATIVE HUMIDITY VALUES WILL
NEED TO BE MONITORED ON MONDAY AND TUESDAY AFTERNOONS, AS THEY
COULD APPROACH 25% IN CENTRAL GEORGIA DURING PEAK HEATING EACH OF
THOSE DAYS.
ON WEDNESDAY, THE AXIS OF THE RIDGE WILL MOVE EAST OF GEORGIA AS THE
ASSOCIATED SURFACE HIGH MOVES OFF THE CAROLINA COAST. MOISTURE WILL
GRADUALLY BEGIN TO INCREASE AS THE FLOW PATTERN SHIFTS TO
SOUTHWESTERLY. AT THIS POINT, THE TUG-OF-WAR BETWEEN FALL AND SUMMER
WILL BE PULLED BACK IN THE FAVOR OF "SUMMER" AS HIGHS REMAIN IN THE
MID 80S TO LOW 90S AND HIGHS RETURN TO THE 60S AND LOW 70S LATE IN
THE WEEK. A LOW PRESSURE SYSTEM MOVING THROUGH THE GREAT PLAINS WILL
EXTEND A COLD FRONT SOUTHWARD, WHICH IS ANTICIPATED TO BRING A
CHANCE OF PRECIPITATION BACK TO PORTIONS OF THE FORECAST AREA LATE
IN THE WEEK. MID-RANGE MODEL GUIDANCE REMAINS HIGHLY INCONSISTENT
WITH THE HANDLING OF THE LOW, WITH SOME SOLUTIONS INDICATING A
WEAKENING OF THE LOW PRESSURE SYSTEM AS IT IS QUICKLY PULLED TO THE
NORTHEAST WHILE OTHERS INDICATE THE SYSTEM FAILING TO BE LIFTED
NORTHEAST BY THE JET STREAM TO THE NORTH AND INSTEAD MEANDERING
ACROSS THE SOUTHERN GREAT PLAINS AND OZARKS REGION. WHICH SOLUTION
MATERIALIZES WILL DETERMINE THE CHANCES AND TIMING OF ANY
PRECIPITATION THAT OCCURS OVER GEORGIA AND WILL WARRANT CONTINUED
MONITORING.
