..NEW 00Z 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
(THIS EVENING THROUGH THURSDAY)
ISSUED AT 310 PM EDT WED AUG 26 2026
A 500 MB TROUGH WILL SET UP OVER THE EASTERN SEABOARD TODAY AND
TOMORROW (THURSDAY). MEANWHILE, PWAT FROM THE GULF AND ATLANTIC
WILL INCREASE, COURTESY OF SOUTHERLY MID-LEVEL FLOW ON THE WESTERN
PERIPHERY OF THE BERMUDA HIGH.
TODAY AND TONIGHT: A STATIONARY FRONT IS ROUGHLY BISECTING THE
CWA, CHARACTERIZED BY A PWAT DIFFERENTIAL (AND THE CUTOFF WHERE A
MORNING CLOUD DECK WAS IN PLACE). NEAR AND SOUTH OF THIS BOUNDARY
IS WHERE CONVECTION WILL LIKELY DEVELOP THIS AFTERNOON AND
EVENING. AMPLE INSTABILITY WILL BE IN PLACE, BUT VIRTUALLY NO
DEEP-LAYER WIND SHEAR (850-300 MB MEAN WINDS ARE 5-10 KTS) SO
SLOW-MOVING STORMS WILL BE CAPABLE OF HEAVY RAINFALL.
ADDITIONALLY, WATER LOADING IN DOWNDRAFTS COULD PRODUCE LOCALIZED
GUSTY WINDS (40-50 MPH). SPC HAS A GENERAL THUNDERSTORM RISK
OUTLINED FOR THE CWA TODAY, SO GENERALLY EXPECTING STORMS TO
REMAIN BELOW SEVERE CRITERIA. THERE WILL BE POTENTIAL FOR SHOWERS
AND STORMS OVERNIGHT AS WELL AMID THIS MORE ACTIVE MID- AND UPPER-
LEVEL PATTERN. THIS POTENTIAL SHOULD NOT COME FROM THE MCS/BROKEN
LINE OF STORMS CURRENTLY MOVING EASTWARD THROUGH ALABAMA,
HOWEVER, AS NECESSARY PARAMETERS FOR MAINTENANCE (BULK SHEAR, MID-
LEVEL LAPSE RATES, AND STEERING WINDS) ARE NOT SUFFICIENT.
TOMORROW: THURSDAY THROUGH EARLY FRIDAY MORNING WILL BRING
INCREASED COVERAGE OF SHOWERS AND STORMS, AS WELL AS THE POTENTIAL
FOR LOCALIZED HEAVY RAINFALL AND FLASH FLOODING. THE HREF 6-HOUR
QPF PMM DEPICTS ISOLATED BULLSEYES OF 2-4 INCHES BETWEEN 18Z (2
PM) AND 00Z (8 PM). SUCH LOCALIZED SWATHS OF HEAVY RAINFALL ARE
DIFFICULT FOR EVEN HI-RES MODELS TO PIN DOWN, SO IT IS TOUGH TO
SAY WHERE EXACTLY THIS MAY OCCUR. THAT SAID, A FEW CONSECUTIVE HI-
RES MODEL CYCLES HAVE ZEROED IN ON THE I-85 CORRIDOR AS A FAVORED
AREA FOR THE HEAVIEST RAINFALL. HI-RES GUIDANCE WILL BEAR WATCHING
TONIGHT AND TOMORROW MORNING.
LONG TERM
(FRIDAY MORNING THROUGH NEXT TUESDAY)
ISSUED AT 310 PM EDT WED AUG 26 2026
THE AXIS OF AN UPPER-LEVEL TROUGH POSITIONED OVER THE GREAT LAKES
REGION WILL SHIFT EASTWARD AND DEEPEN SLIGHTLY THROUGH FRIDAY
BEFORE PULLING OFF TOWARD THE NORTHEAST INTO THE WEEKEND. ON
FRIDAY, A SURFACE FRONT IS LIKELY TO STALL OVER THE NORTH TO
CENTRAL TIER OF OUR CWA, ACTING AS A FOCAL POINT FOR MULTIPLE
ROUNDS OF SCATTERED TO WIDESPREAD SHOWERS AND THUNDERSTORMS.
PRECIPITABLE WATER VALUES WILL BE IN EXCESS OF 2 INCHES OVER THE
AREA, SUPPORTING HEAVY RAINFALL TOTALS AND LOCALIZED FLASH
FLOODING CONSIDERATIONS THROUGH THE FIRST HALF OF THE WEEKEND. IN
LINE WITH THIS, THE WEATHER PREDICTION CENTER HAS OUR AREA IN A
MARGINAL RISK FOR EXCESSIVE RAINFALL, SO WE WILL NEED TO MONITOR
RAINFALL RATES WITH SOME OF THESE STORMS. ADDITIONALLY, THE STORM
PREDICTION CENTER DOES BRING A MARGINAL RISK OF SEVERE WEATHER
INTO THE NORTH-NORTHEAST PORTIONS OF OUR CWA ON FRIDAY, WITH
POSSIBLE DAMAGING WIND GUSTS BEING THE PRIMARY THREAT. WITH AMPLE
CLOUD COVER AND A WETTER OVERALL PATTERN, DAYTIME HIGH
TEMPERATURES WILL BE HELD DOWN SLIGHTLY, RANGING FROM THE MID-80S
TO LOW-90S ACROSS THE AREA THROUGH THE END OF THE WEEKEND.
RAIN AND THUNDERSTORM CHANCES BEGIN TO DECREASE AS WE MOVE INTO
THE SECOND HALF OF THE WEEKEND, AS A BROAD UPPER-LEVEL RIDGE
BEGINS TO BUILD AND SHIFT OVER THE AREA BY EARLY NEXT WEEK. IN
RESPONSE, HIGH TEMPERATURES WILL CLIMB BACK INTO THE MID-90S, WITH
DEWPOINTS IN THE 70S WITH POSSIBLE HEAT ADVISORY CONSIDERATIONS
BY MID NEXT WEEK. SO IF YOU ENJOY SUMMERTIME WEATHER, WE REMAIN
LOCKED IN THIS PATTERN WITH DIURNALLY DRIVEN THUNDERSTORMS FOR THE
EXTENDED FORECAST.
AVIATION
(00Z TAFS)
ISSUED AT 718 PM EDT WED AUG 26 2026
SHOWERS AND SOME ISOLATED THUNDERSTORMS ACROSS THE AREA THIS
AFTERNOON/EVENING. LOOKS LIKE WE COULD SEE THEM AFFECT THE TAF
SITES OVER THE NEXT FEW HOURS THEN DISSIPATE THROUGH MIDNIGHT. WE
COULD ALSO SEE COME LOW CEILINGS AROUND SUNRISE LIFTING AND SCT
OUT BY 14Z-15Z. WILL SEE ANOTHER ROUND OF SHRA/TSRA THU
AFTERNOON/EVENING WITH A BIT MORE COVERAGE THAN TODAY. WINDS WILL
BE LIGHT AND VRB OVERNIGHT INCREASING OUT OF THE SW THU AFTERNOON
INTO THE 5-10KT RANGE. WILL SEE SOME GUSTY VRB WINDS IN AND
AROUND AFTERNOON CONVECTION IN THE 15-25KT RANGE.
//ATL CONFIDENCE...00Z UPDATE...
