AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
152 PM EDT WED AUG 26 2026
..NEW 18Z AVIATION DISCUSSION
KEY MESSAGES
- SCATTERED TO NUMEROUS SHOWERS AND STORMS EXPECTED EACH DAY
THROUGH THE WEEKEND.
- HEAVY RAINFALL MAY LEAD TO LOCALIZED FLOODING ACROSS NORTH
GEORGIA AND PARTS OF CENTRAL GEORGIA THURSDAY INTO FRIDAY.
- GENERALLY SEASONABLE TEMPERATURES WILL CONTINUE THROUGH THE
WEEKEND.
SHORT TERM
(TODAY THROUGH THURSDAY)
ISSUED AT 355 AM EDT WED AUG 26 2026
A QUIET START TO WHAT WILL BE A MORE ACTIVE PERIOD ACROSS NORTH
AND CENTRAL GEORGIA. LOW CLOUDS AND PATCHY FOG WILL FILL IN ACROSS
PARTS OF CENTRAL GEORGIA AND COULD BRIEFLY DEVELOP AS FAR SOUTH
AS THE METRO THROUGH RIGHT AROUND SUNRISE.
THE FORECAST AREA REMAINS WITHIN A QUASI- NW FLOW REGIME. A WEAK
FRONTAL BOUNDARY REMAINS DRAPED ACROSS CENTRAL GEORGIA, ROUGHLY
FROM COLUMBUS TO MACON, BASED ON CURRENT DEWPOINT OBSERVATIONS.
CONTINUED MOISTURE RETURN AND INSTABILITY WILL SUPPORT HIGHER
COVERAGE OF SCATTERED SHOWERS AND STORMS THIS AFTERNOON. CAMS ARE
STILL ALL OVER THE PLACE WITH PLACEMENT AND COVERAGE BUT IT IS
ANTICIPATED THAT THE FRONTAL BOUNDARY AND THE THERMAL GRADIENT
FROM THIS MORNING'S CLOUD COVER IS LIKELY WHERE CONVECTION WILL
GET STARTED LATER TODAY. ALL STORMS WILL BE CAPABLE OF FREQUENT
LIGHTNING, GUSTY WINDS, AND LOCALLY HEAVY RAINFALL. COVERAGE OF
SHOWERS AND STORMS SHOULD DECREASE FOLLOWING SUNSET GIVEN LOSS OF
DAYTIME HEATING BUT I IMAGINE ISOLATED ACTIVITY MAY LINGER.
ADDITIONALLY, SEVERAL HI-RES MODELS STILL INDICATE A POTENTIAL MCS
(CLUSTER OF THUNDERSTORMS) TRACKING SOUTHEASTWARD INTO PARTS OF
AL OVERNIGHT BUT IT'S UNCLEAR IF THIS WILL HOLD TOGETHER OR EVEN
MAKE IT TO NW/W GA. FOR NOW MAINTAIN LOW CHANCES (15-20%) FOR
SHOWERS AND THUNDERSTORMS OVERNIGHT.
MIDLEVEL TROUGHING WILL ENCOMPASS MUCH OF THE EASTERN U.S. AND A
VORT MAX WITHIN THE FLOW WILL PUSH A COLD FRONT TOWARDS THE
FORECAST AREA ON THURSDAY. AMPLE INSTABILITY, PLENTIFUL MOISTURE
(PWS 1.7- 2.1") AND FLOW NEARLY PARALLEL TO THE INCOMING BOUNDARY
WILL SUPPORT SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS
ACROSS ALL OF NORTH AND CENTRAL GA. LIMITED SHEAR AND HIGH
MOISTURE CONTENT WILL MEAN STORMS WILL BE SLOW-MOVING, HEAVY RAIN
PRODUCERS. THUS, LOCALLY HEAVY RAINFALL AND A THREAT FOR FLASH
FLOODING IS LIKELY. WPC MAINTAINS A SLIGHT RISK (LEVEL 2 OF 4) OF
EXCESSIVE RAINFALL FOR MUCH OF NORTH GA ON THURSDAY, GIVEN RECENT
TRENDS. DEPENDING ON HOW THINGS EVOLVE, A FLOOD WATCH MAY BE
NEEDED ACROSS PARTS OF NORTH GA. WHILE WIDESPREAD SEVERE WEATHER
REMAINS LOW THROUGH THE SHORT-TERM, HIGH MOISTURE CONTENT WILL
RESULT IN HEAVILY WATER-LOADED DOWNDRAFTS WITH ANY STORMS. THUS,
STRONG GUSTY WINDS CANNOT BE RULED OUT.
TEMPERATURES WILL REMAIN FAIRLY SEASONABLE BOTH TODAY AND
THURSDAY. THIS AFTERNOON DAYTIME HIGHS WILL RISE INTO THE 90S
(5-10 DEG COOLER IN THE MOUNTAINS) WITH HEAT INDICES IN THE
100-104F RANGE ACROSS CENTRAL GA. ON THURSDAY, TEMPERATURES WILL
BE A FEW DEGREES COOLER AS A RESULT OF HIGHER CLOUD COVERAGE AND
STORM COVERAGE.
LONG TERM
(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 355 AM EDT WED AUG 26 2026
STARTING OFF THE LONG TERM OUTLOOK ON FRIDAY, THE UPPER LEVEL
WAVE BREAK PATTERN WILL CONTINUE TO BRING SCATTERED TO WIDESPREAD
SHOWERS AND THUNDERSTORMS TO MUCH OF NORTH AND CENTRAL GA. PWATS
IN EXCESS OF 2 INCHES WILL MEAN HEAVY SOAKING RAINS MAY CONTINUE
FROM PREVIOUS DAYS. THE OVERALL RISK FOR SEVERE WEATHER THROUGH
THE LONG TERM REMAINS FAIRLY LOW. THUNDERSTORMS ON FRIDAY ARE
LIKELY TO DEVELOP IN AREAS WHICH HAVE ALREADY BEEN WORKED OVER
WITH LIMITED ORGANIZATION.
MOVING INTO THE WEEKEND, UPPER LEVEL FLOW SHIFTS EASTWARD
BRINGING BROAD RIDGING BACK OVERHEAD. HIGH TEMPERATURES WILL
RETURN TO THE 90S WITH DEWPOINTS IN THE 70S. JUST ANOTHER BLAST OF
THE SUMMER SAUNA. THUNDERSTORMS POTENTIAL DROPS THROUGH THE
WEEKEND, THOUGH ISOLATED TO SCATTERED DIURNALLY DRIVEN
THUNDERSTORMS REMAIN POSSIBLE. PWATS FALLING BELOW 2 INCHES WILL
ALSO REDUCE THE RISK FOR FLASH FLOODING.
AVIATION
(18Z TAFS)
ISSUED AT 135 PM EDT WED AUG 26 2026
SCT CU FIELD AROUND 5-7 KFT EXPECTED THROUGH THE AFTERNOON AND
EARLY EVENING. PROB30S AT ALL TAF SITES RUN FROM 19Z TO 23Z FOR
NOW TO CAPTURE PEAK TSRA POTENTIAL. ISOLATED SHRA/TSRA MAY PERSIST
OVERNIGHT, BUT THE PROBABILITY IS TOO LOW TO INCLUDE IN THE TAFS.
AREAS OF LOW CIGS (MVFR TO IFR) AND REDUCED VIS ARE EXPECTED TO
DEVELOP OVERNIGHT INTO TOMORROW (THURSDAY) MORNING, BUT
LOCATION/COVERAGE MAY DEPEND ON WHERE CONVECTION OCCURS TODAY AND
IS SOMEWHAT UNCERTAIN. SCT TSRA EXPECTED AGAIN TOMORROW AFTERNOON
AND EVENING.
//ATL CONFIDENCE...18Z UPDATE...
MEDIUM CONFIDENCE ON PROB30 TIMING TODAY AND TIMING/COVERAGE OF
CONVECTION TOMORROW. HIGH CONFIDENCE ON ALL OTHER ELEMENTS.
