SHORT TERM
(TODAY THROUGH FRIDAY)
ISSUED AT 314 AM EDT THU AUG 27 2026
CURRENTLY: A FEW SPOTTY SHOWERS HAVE ALREADY BEGUN TO POP UP ACROSS
THE AREA THIS MORNING PER LATEST RADAR IMAGERY. THOUGH THE MAIN
ACTION IS WELL TO OUR WEST ACROSS THE ARKLAMISS WHERE A STORM
COMPLEX IS PUSHING SOUTHWARD. HIGH CIRRUS FROM THIS COMPLEX IS
BEGINNING TO BLANKET ACROSS THE AREA WITH LOW TO MID-LEVEL CLOUDS
STARTING TO FILL IN UNDERNEATH. ISOLATED SHOWERS AND PERHAPS A
RUMBLE OF THUNDER WILL BE POSSIBLE THROUGH THE MORNING AND IS NOT
EXPECTED TO COME FROM THE STORM COMPLEX TO OUR WEST.
STORM CHANCES AND FLOOD POTENTIAL: INCREASED COVERAGE OF SHOWERS AND
STORMS AS WELL AS A POTENTIAL FOR LOCALLY HEAVY RAINFALL AND
ISOLATED INSTANCES OF FLASH FLOODING IS ANTICIPATED FOR TODAY INTO
FRIDAY. A WEAK FRONTAL BOUNDARY OVER CENTRAL GA (ROUGHLY LAGRANGE TO
SOUTH OF ATHENS) WILL BE THE INITIAL FOCUS AREA FOR STORM
DEVELOPMENT LATER TODAY. THE MOST NOTABLE CHANGE FROM PREVIOUS
FORECASTS IS A SHIFT IN THE AREA OF HIGHEST MOISTURE -- REFLECTED IN
THE LATEST PW ANALYSIS AND HREF 6-HR QPF PMM. LIKELY A RESULT OF
STORM COMPLEX TO OUR SOUTHWEST. WHILE THE SIGNAL FOR HEAVY RAINFALL
AND FLASH FLOODING IS NOT QUITE AS STRONG FOR TODAY, HIGH MOISTURE
CONTENT IN THE ATMOSPHERE (PWS 1.5-1.8") MEANS STORMS WILL STILL BE
EFFICIENT RAIN-PRODUCERS. THIS COUPLED WITH LIMITED SHEAR MEANS
STORMS MAY STILL PRESENT A LOCALIZED FLASH FLOOD THREAT DUE TO HEAVY
RAINFALL IN A SHORT PERIOD OR DUE TO STORMS REPEATEDLY MOVING OVER
THE SAME AREAS. EXACTLY WHERE THESE STORMS SET UP IS THE BIGGEST
QUESTION BUT I SUSPECT IT WILL BE IN THE VICINITY OF THE FRONTAL
BOUNDARY DRAPED OVER THE AREA. COVERAGE OF SHOWERS AND STORMS SHOULD
BEGIN DECREASING AFTER SUNSET BUT ISOLATED SHOWER AND STORMS COULD
CONTINUE OVERNIGHT. A VORT MAX WILL USHER ANOTHER FRONT TOWARDS THE
FORECAST AREA TONIGHT AND IT WILL LIKELY STALL JUST NORTH OF THE
AREA. AMPLE MOISTURE SOUTH OF THIS BOUNDARY AND TEMPERATURES WARMING
INTO THE MID TO UPPER 80S ON FRIDAY MAY SUPPORT POCKETS OF MODERATE
INSTABILITY ACROSS NORTH GA. WHILE SHEAR WILL BE FAIRLY WEAK, IF ANY
STORMS ARE ABLE TO TAKE ADVANTAGE OF THE FLOW ALOFT, THEY COULD BE
CAPABLE OF PRODUCING STRONG TO DAMAGING WIND GUSTS. THIS THREAT IS
HIGHLIGHTED BY A MARGINAL RISK (LEVEL 1 OF 5) BY SPC FOR FRIDAY
ACROSS PARTS OF NORTH GA.
TEMPERATURE TRENDS: SEASONABLE TEMPERATURES ARE LARGELY EXPECTED FOR
TODAY AND FRIDAY. HIGHER CLOUD COVER BOTH DAYS WILL RESULT IN
DAYTIME HIGHS IN THE 80S TO LOW 90S. MORNING LOWS ARE FORECAST TO BE
IN THE UPPER 60S TO LOW 70S (SLIGHTLY COOLER IN THE MOUNTAINS).
LONG TERM
(FRIDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 314 AM EDT THU AUG 27 2026
RATHER UNSURPRISING, THE UPPER LEVEL PATTERN GOING INTO THE LONG
TERM OUTLOOK (BEGINNING SAT) IS DEPENDENT ON THE SPEED AT WHICH THE
EASTERN CONUS TROUGH EXITS THE AREA. ENSEMBLE ANALYSIS SHOWS THE
MAJORITY (68%) OF MEMBERS FROM GEFS AND ENS MOVE THE TROUGH OUT ON
SATURDAY, WITH ONLY 6-12% HOLDING THE TROUGH INTO LATE
SATURDAY/EARLY SUNDAY. WHAT THIS MEANS IS ONE LAST ENHANCED DAY FOR
UPPER LEVEL ENHANCEMENT OF PRECIP, BEFORE THE RIDGE MOVES OVERHEAD.
GIVEN PWATS OVER 2" AND SLOW MOVING/GREATER COVERAGE OF STORMS,
EXCESSIVE RAINFALL IS POSSIBLE INTO SATURDAY. THIS WILL BE
ESPECIALLY TRUE FOR AREAS WHICH SEE HEAVY RAIN IN DAYS PRIOR.
AS THE RIDGE MOVES OVERHEAR, CONDITIONS WILL TRANSITION MORE TO A
TYPICAL SUMMERTIME PATTERN WITH HIGHS IN THE 90S AND HEAT INDICES
BACK IN THE TRIPLE DIGITS. WHILE AFTERNOON THUNDERSTORMS COVERAGE
WON'T BE NEARLY AS HIGH, WE WILL LIKELY SEE DISORGANIZED DIURNAL
CONVECTION EACH AFTERNOON THROUGH NEXT WEEK. AS IS COMMON WITH
SUMMERTIME CONVECTION, A FEW STORMS COULD BECOME STRONG TO EVEN
SEVERE EACH AFTERNOON WITH GUSTY WINDS, FREQUENT LIGHTNING, AND
LOCALLY HEAVY RAINFALL.
