..NEW 06Z AVIATION DISCUSSION
KEY MESSAGES
- ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS IS POSSIBLE TONIGHT
THROUGH EARLY THURSDAY. SOME STORMS MAY BECOME STRONG TO
MARGINALLY SEVERE AND CAPABLE OF PRODUCING ISOLATED DAMAGING
WIND GUSTS AND SMALL HAIL.
- TEMPERATURES WILL REMAIN WITHIN A FEW DEGREES OF NORMAL TO ROUND
OFF THE WEEK, WITH A COOLDOWN (HIGHS IN THE 60S) THIS WEEKEND.
SHORT TERM
(THIS EVENING THROUGH THURSDAY)
ISSUED AT 357 PM EDT WED APR 29 2026
WITH LOW CLOUD CEILINGS LIFTING AND SCATTERING DURING THE MID-
MORNING HOURS INTO THE EARLY AFTERNOON, TEMPERATURES HAVE BEEN ABLE
TO WARM INTO THE UPPER 70S TO LOW 80S IN NORTH GEORGIA AND MID 80S
IN CENTRAL GEORGIA. HIGHS COULD FURTHERMORE RISE INTO THE UPPER 80S
IN EAST-CENTRAL GEORGIA IN THE PEAK HEATING HOURS. WITH VEERED
SURFACE WINDS AHEAD OF THE COLD FRONT AND LIMITED LARGE-SCALE
ASCENT, SUSTAINED WIDESPREAD CONVECTION IS NOT EXPECTED THIS
AFTERNOON. HOWEVER, ISOLATED TO WIDELY SCATTERED THUNDERSTORMS
CANNOT BE RULED OUT IN PORTIONS OF NORTH GEORGIA, IN AND TO THE
NORTH OF THE ATLANTA METRO WHERE SURFACE HEATING AND CONVECTION CAN
OVERCOME WEAK CAPPING. THUNDERSTORMS THAT ARE ABLE TO DEVELOP COULD
TAP INTO SBCAPE VALUES BETWEEN 1500-2500 J/KG AND 700-500 MB LAPSE
RATES BETWEEN 7.5-8 C/KM. SO, IF WE DO SEE STORMS, A COUPLE OF THEM
COULD BECOME STRONG TO SEVERE IN THIS ENVIRONMENT, CAPABLE OF
PRODUCING HAIL AND GUSTY WINDS.
TONIGHT, A SHORTWAVE WILL TRAVERSE THE MID-LEVEL ZONAL FLOW,
OVERRUNNING A STALLED FRONTAL BOUNDARY DRAPED ACROSS THE NORTHERN
GULF COAST. THIS SHORTWAVE WILL SUPPORT ANOTHER SYSTEM OF QUASI-
ORGANIZED THUNDERSTORMS, WHICH HAS ALREADY BEGUN TO DEVELOP ACROSS
SOUTHERN MISSISSIPPI. HI-RES GUIDANCE HAS BEEN COMING INTO BETTER
AGREEMENT THAT THE SYSTEM WILL ENTER WEST-CENTRAL GEORGIA JUST
BEFORE MIDNIGHT, CONTINUING NORTHEAST TOWARDS THE ATLANTA METRO AND
FURTHER TOWARDS ATHENS/GAINESVILLE DURING THE EARLY MORNING HOURS. A
MARGINAL (LEVEL 1 OUT OF 5) RISK REMAINS IN EFFECT ACROSS CENTRAL
GEORGIA. HERE, SLIGHTLY GREATER MOISTURE WITH DEWPOINTS REMAINING IN
THE MID 60S AND SBCAPE VALUES REMAINING AS HIGH AS 1000-1500 J/KG
WILL BE FAVORABLE FOR THUNDERSTORM MAINTENANCE. A LOOK AT HI-RES
MODEL SOUNDINGS ALSO REVEALS THE POTENTIAL FOR 0-1 KM SHEAR OF 20-25
KTS ON THE LEADING EDGE OF THE SYSTEM. THUS, STRONG, POTENTIALLY
DAMAGING WIND GUSTS WILL BE POSSIBLE WITHIN THE STRONGEST STORMS ON
THE LEADING EDGE OF THE SYSTEM.
BROKEN LOW CLOUDS IN THE MORNING AFTER DAYBREAK WILL BEGIN TO
SCATTER OUT IN THE LATE MORNING AND EARLY AFTERNOON. HIGHS WILL BE
COOLER THAN OBSERVED TODAY, LARGELY IN THE LOW TO MID 70S ALONG AND
NORTH OF I-85 AND IN THE UPPER 70S TO NEAR 80 TO THE SOUTH. AFTER
TRAILING SHOWERS BEHIND THE CONVECTIVE SYSTEM COME TO AN END ACROSS
THE MAJORITY OF THE AREA, SLIGHT CHANCE TO LOW-END CHANCE POPS (15-
30%) ARE ANTICIPATED TO PERSIST IN THE FAR SOUTHERN TIER IN THE
VICINITY OF THE STALLED FRONTAL BOUNDARY.
LONG TERM
(FRIDAY MORNING THROUGH NEXT TUESDAY)
ISSUED AT 357 PM EDT WED APR 29 2026
GENERALLY UNSETTLED WEATHER IS EXPECTED TO CONTINUE AS THE LONG TERM
PICKS UP AS THE UPPER LEVEL TROUGH FINALLY PUSHES OUT SATURDAY
AFTERNOON AND INTO THE EVENING. MOST OF THE ACTIVITY WILL BE RAIN,
THOUGH INSTABILITY COULD BUILD ACROSS PORTIONS OF THE SOUTHERN PART
OF THE CWA THROUGH MID AFTERNOON TO RESULT IN SOME THUNDERSTORMS
SOUTH OF A LINE FROM COLUMBUS TO MACON. WHILE WIDESPREAD SEVERE
WEATHER IS NOT EXPECTED, A FEW STRONG STORMS COULD BE POSSIBLE.
HIGH PRESSURE ESTABLISHES ON SUNDAY AND KICK OFF ANOTHER DRY PERIOD
WITH BUILDING HEAT. MODEST TEMPERATURES ON SUNDAY IN THE UPPER 60S
AND LOW 70S WILL QUICKLY REBOUND ON MONDAY AS THEY CLIMB BACK INTO
THE UPPER 70S AND 80S FOR THE REMAINDER OF THE WEEK. THIS WILL BE
ACCOMPANIED BY DRIER CONDITIONS, WITH RELATIVE HUMIDITY FALLING INTO
THE 30% DURING THE AFTERNOON.
OVERNIGHT LOWS SUNDAY INTO MONDAY WILL BE IN THE LOW 40S WITH SOME
UPPER 30S POSSIBLE ACROSS THE HIGHER ELEVATIONS. LOWS WILL REBOUND
WITH THE HIGHS AND BY THE END OF THE WEEK, THEY'LL CLIMB BACK INTO
THE MID TO UPPER 50S.
