..NEW 12Z AVIATION DISCUSSION
KEY MESSAGES

THROUGH THE WEEKEND.
- HEAVY RAINFALL MAY LEAD TO LOCALIZED FLOODING ACROSS NORTH GEORGIA
ON THURSDAY.
- 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.
