..NEW 12Z AVIATION DISCUSSION
KEY MESSAGES
- A FEW SCATTERED THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON ALONG
THE GA/AL BORDER, BUT COVERAGE WILL BE MUCH LESS THAN YESTERDAY.
- WARMER TEMPERATURES THE NEXT FEW DAYS WITH HIGHS IN THE UPPER
80S TO LOW 90S.
- INCREASED RAIN CHANCES RETURN FROM WEDNESDAY INTO NEXT WEEKEND.
SHORT TERM
(TODAY THROUGH TUESDAY)
ISSUED AT 500 AM EDT MON MAY 18 2026
ANOTHER WARM DAY EXPECTED THIS AFTERNOON AS TEMPERATURES RISE INTO
THE UPPER 80S AND LOW 90S. THE BEST CHANCE FOR AFTERNOON
THUNDERSTORMS HAS SHIFTED TO THE WEST, THOUGH A FEW ISOLATED
THUNDERSTORMS ARE POSSIBLE ALONG THE GA/AL BORDER THIS AFTERNOON.
COVERAGE SEEMS TO BE SIGNIFICANTLY LESS THAN YESTERDAYS STORMS.
INSTABILITY WILL BE A LIMITING FACTOR AS WELL WITH HIGH PRESSURE
KEEPING A CAP ON MOST OF THE CWA.
THE FORECAST FOR TUESDAY IS A BIT OF A CARBON COPY FOR TODAY THOUGH
WITH INCREASING AFTERNOON CLOUDS OUT A HEAD OF THE COLD FRONT THAT'S
EXPECTED TO BRING THE NEXT ROUND OF WEATHER. YOU CAN FIND MORE
INFORMATION ABOUT THAT SYSTEM IN THE LONG TERM BELOW. WINDS WILL
REMAIN SOUTHERLY AT 5-10MPH WITH SOME HIGHER GUSTS IN THE HIGHER
ELEVATIONS OF NORTHERN GEORGIA. OVERNIGHT LOWS WILL BE PLEASANTLY IN
THE MID 60S.
LONG TERM
(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 500 AM EDT MON MAY 18 2026
BY WEDNESDAY AFTERNOON AND EVENING, A COLD FRONT WILL PUSH
SOUTHEASTWARD TOWARD FAR NORTH GEORGIA. THE HIGHEST POPS WILL BE
RELEGATED TO THESE AREAS IN PROXIMITY TO THE FRONTAL FORCING WITH
DRIER CONDITIONS INITIALLY FAVORED FARTHER SOUTHEAST.
THE FRONT MAKES ONLY LIMITED SOUTHWARD PROGRESS BY THURSDAY INTO
NORTH GEORGIA AS UPPER SUPPORT DEPARTS NORTHEASTWARD FROM THE GREAT
LAKES INTO QUEBEC. AS SUCH, DIURNALLY-ENHANCED POPS SHOULD AGAIN BE
HIGHEST ALONG/NORTH OF THE I-20 CORRIDOR. FLOW ALOFT THEN
TRANSITIONS INTO SOUTHWEST FLOW BY LATE WEEK AS THE FRONT BECOMES
STATIONARY. WEAK SHORTWAVES WITHIN THIS FLOW WILL ENHANCE CONVECTIVE
COVERAGE HEADED INTO THE WEEKEND, PARTICULARLY WITH THE AID OF
DIURNAL HEATING. COVERAGE AGAIN WILL LIKELY BE HIGHEST ACROSS
ROUGHLY THE NORTHERN HALF OF THE AREA THROUGH THIS PERIOD. THE
ORGANIZED SEVERE THREAT CONTINUES TO LOOK LOW GIVEN THE SUMMER-LIKE
WEAKLY SHEARED ENVIRONMENT, A COUPLE OF STRONG TO ISOLATED SEVERE
STORMS CERTAINLY CAN'T BE RULED OUT. WHILE LOCALLY HEAVY RAINFALL
WILL ALSO BE POSSIBLE, THE LACK OF A WIDESPREAD AND PERSISTENT
SOAKING RAINFALL WILL LIMIT THE OVERALL IMPACT ON THE DROUGHT
THROUGH THE FORECAST PERIOD.
TEMPERATURES REMAIN GENERALLY SEVERAL DEGREES ABOVE NORMAL (HIGHS IN
THE MID TO UPPER 80S TO LOWER 90S ON THE WARMEST DAYS AND LOWS IN
THE 60S), THOUGH MARGINALLY COOLER HIGHS ARE POSSIBLE LATE WEEK
GIVEN INCREASED CLOUDS AND CONVECTIVE COVERAGE.
