201 PM EDT TUE SEP 2 2025
..NEW 18Z AVIATION DISCUSSION
SHORT TERM
(TODAY THROUGH WEDNESDAY)
ISSUED AT 224 AM EDT TUE SEP 2 2025
KEY MESSAGES:
- ISOLATED SHOWERS ARE POSSIBLE ACROSS PORTIONS OF NORTH GEORGIA
TODAY, WITH CHANCES INCREASING ON WEDNESDAY.
- AFTERNOON HIGHS WILL CONTINUE TO INCH BACK TOWARD SEASONAL
NORMS, TOPPING OUT IN THE 80S.
DISCUSSION:
WITH A BROAD SURFACE HIGH PRESSURE SYSTEM SPLAYED ACROSS MUCH OF THE
GREAT LAKES, SOUTHERN CANADA, AND NEW ENGLAND, WEDGING OF COOL,
CONTINENTAL AIR CONTINUES ACROSS MUCH OF NORTH AND CENTRAL GEORGIA --
CHARACTERISTIC U-SHAPED ISOBARS ARE SEEN EXTENDING AS FAR WEST AS
ALABAMA/MISSISSIPPI. THIS WILL HELP KEEP CONDITIONS MILD AND DRY
(POPS <20%) FOR A MAJORITY OF THE FORECAST AREA TODAY. THE EXCEPTION
WILL BE FOR PORTIONS OF FAR NORTH GEORGIA, WHERE CONVERGENT FLOW
AROUND THE EDGE OF THE WEDGE AIRMASS ALONG WITH SOME OROGRAPHIC
INFLUENCE WILL SUPPORT THE DEVELOPMENT OF ISOLATED DIURNALLY-
DRIVEN SHOWERS AND PERHAPS A THUNDERSTORM OR TWO.
MOVING INTO WEDNESDAY, A SHORTWAVE TRAVERSING THE SOUTHERN EDGE OF
BROADER MID-LEVEL TROUGHING WILL SWEEP ACROSS THE TENNESSEE RIVER
VALLEY, WEAKENING THE WEDGE AIRMASS/COOL DOME TO THE NORTH. SURFACE
WINDS WILL VEER TO THE SOUTH OVER THE COURSE OF THE DAY, ALLOWING
FOR THE INTRUSION OF WARMER, MORE MOISTURE-RICH AIR (DEWPOINTS
RETURNING TO THE 60S). THIS COMBINED WITH IMPROVED FORCING IN THE
VICINITY OF THE AFOREMENTIONED WAVE WILL ALLOW FOR SLIGHTLY
BOLSTERED CHANCES FOR CONVECTION AS WE APPROACH MIDWEEK. ISOLATED
TO SCATTERED THUNDERSTORMS (30-50% CHANCES) ARE POSSIBLE
PRIMARILY ALONG AND NORTH OF THE I-20/I-85 INTERCHANGE BEGINNING
EARLY IN THE MORNING, INCREASING IN COVERAGE INTO THE EVENING.
TEMPERATURES WILL CONTINUE TO MODERATE WITH REBOUNDING MOISTURE,
TOPPING OUT IN THE LOW-TO-MID 80S TODAY AND WARMING BY JUST A FEW
DEGREES FOR WEDNESDAY. EXPECT LOWS IN THE MID-50S TO LOWER 60S.

KEY MESSAGES:
- ISOLATED TO SCATTERED SHOWERS AND STORMS THU, WITH DRIER
CONDITIONS EXPECTED FRI, SAT, AND SUN.

THE EXTENDED FORECAST STARTS OF WITH ISOLATED DIURNALLY DRIVEN
SHOWERS AND THUNDERSTORMS THU BUT THEN THE FIRST OF TWO FRONTAL
BOUNDARIES MOVES THROUGH THE AREA. THE 1ST FRONTAL BOUNDARY MOVES SE
THROUGH THE AREA THU EVENING/NIGHT AND BEGINS TO DRY THINGS OUT FOR
FRI. THE SECOND FRONT PUSHES OUT OF THE NORTHERN PLAINS FRI AND INTO
NW GA SAT MORNING. DEPENDING ON WHICH MODEL YOUR LOOKING AT (ECMWF
OR GFS) THIS SECOND FRONT WILL BE FAIRLY DRY AND PUSH THROUGH THE
AREA DRYING THINGS OUT FOR THE WEEKEND (ECMWF). THE GFS IS SHOWING
JUST THE OPPOSITE WITH THIS FRONT STALLING ACROSS CENTRAL GA SAT
NIGHT AND BRINGING IN MORE PRECIPITATION THROUGH THE BEGINNING OF
NEXT WEEK. THE MODELS ARE IN GOOD AGREEMENT RIGHT UP TO THIS POINT
SO FOR NOW WILL JUST GO WITH MORE OF A CONSISTENCY FORECAST AND KEEP
THINGS MOSTLY DRY SAT/SUN.
