AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
809 PM EDT WED MAY 20 2026
..NEW 00Z AVIATION DISCUSSION
KEY MESSAGES
- SUMMER ARRIVES WITH HIGHS IN THE 80S AND 90S THROUGH THE BEGINNING
OF NEXT WEEK.
- DAILY ROUNDS OF RAIN AND THUNDERSTORMS ARE EXPECTED FROM TODAY
THROUGH THE HOLIDAY WEEKEND AND BEYOND FOR ALL OF NORTH AND CENTRAL
GEORGIA. PLEASE REMEMBER TO FOLLOW LIGHTNING SAFETY FOR ANY OUTDOOR
ACTIVITIES - IF THUNDER ROARS, GO INDOORS!
SHORT TERM
(THIS AFTERNOON THROUGH THURSDAY)
ISSUED AT 238 PM EDT WED MAY 20 2026
SHOWERS AND THUNDERSTORMS DEVELOPING ACROSS MAINLY NORTH AND WESTERN
PORTIONS OF THE STATE. THE MAIN FRONTAL BOUNDARY IS STILL WEST OF
THE STATE ACROSS TN/AL PUSHING SLOWLY EAST INTO THE BERMUDA RIDGE
CENTERED OFF THE CAROLINA COAST. THIS RIDGE IS ALSO SLOWLY WEAKENING
AND SHOULD CONTINUE TO DIMINISH THROUGH THU. THIS WILL ALLOW THE
FRONTAL BOUNDARY TO PUSH INTO NW GA SHORTLY AFTER MIDNIGHT TONIGHT.
AS A RESULT, THIS WILL KEEP PRECIP CHANCES ELEVATED ACROSS NW GA
OVERNIGHT WITH MAINLY SHOWERS AND ISOLATED THUNDERSTORMS. WE WILL
SEE ANOTHER ROUND OF DIURNALLY DRIVEN SHOWERS AND THUNDERSTORMS THU
WITH AREAS SOUTH AND EAST SEEING SOME PRECIPITATION. THERE IS A
CHANCE TODAY AND THU THAT WE COULD SEE AN ISOLATED STRONG TO SEVERE
STORM BUT INSTABILITY, SHEER, AND A LIFTING MECHANISM ARE NOT TO
PREVALENT WITH THE RIDGE STILL KEEPING THINGS FAIRLY CAPPED
TEMPS WILL FALL INTO THE MID 60S AGAIN OVERNIGHT WITH HIGH TEMPS THU
LOOKING SIMILAR TO TODAY.
LONG TERM
(FRIDAY MORNING THROUGH NEXT TUESDAY)
ISSUED AT 238 PM EDT WED MAY 20 2026
THE LONGER TERM FORECAST LOOKS A LOT LIKE SUMMER IN THE SOUTH -
WARM, PLENTY OF MOISTURE, AND DIURNALLY DRIVEN THUNDERSTORM CHANCES
GALORE WITH SOME AID FROM SHORTWAVES MOVING THROUGH. WHILE THIS
FORECASTER IS A BIT SAD ABOUT THE IMPENDING RETURN OF AIR YOU CAN
WEAR TO THE AREA, WE REALLY COULD USE THE RAIN TO HELP CONTINUE TO
ALLEVIATE OR AT LEAST PREVENT WORSENING OF OUR DROUGHT CONDITIONS.
THIS WILL CONTINUE THROUGH THE HOLIDAY WEEKEND WITH POTENTIAL
IMPACTS TO OUTDOOR ACTIVITIES. PLEASE KEEP THIS IN MIND AND REMAIN
WEATHER AWARE.
DIVING INTO THE NERDY DETAILS, ENSEMBLES SHOW VERY CLEAR SIGNAL FOR
SOUTHWEST FLOW ALOFT TO BUILD INTO THE SOUTHEAST. THIS IS TYPICALLY
A FLOW REGIME THAT SETS US UP FOR RAIN, AND THE FORECAST REFLECTS
THAT. FLOW ALOFT IS SPLIT OVER THE WEST COAST, ALLOWING US TO TAP
INTO THE SUBTROPICAL JET/AIRMASS HERE IN THE SOUTH. SHORTWAVES
WITHIN THAT WILL MOVE ACROSS THE AREA ON ANY GIVEN DAY, ENHANCING
THUNDERSTORM CHANCES ON APPROACH, AND IN SOME CASES MAY DRIVE
EARLIER RAIN OR THUNDERSTORMS THAN WOULD NORMALLY OCCUR WITHIN A
PURELY DIURNAL SETUP. HIGHEST CHANCE OF THIS LOOKS TO BE WITH A WAVE
MOVING THROUGH FRIDAY NIGHT INTO SATURDAY MORNING THAT MAY DRIVE
MORE WIDESPREAD HEAVY RAINFALL. CURRENT HIGH TEMPERATURES ARE
REFLECTIVE OF WHAT OCCURS IN LOCATIONS THAT DON'T SEE THUNDERSTORMS -
EXPECTATION IS THAT SOME AREAS WON'T MEET THESE NUMBERS, BUT
PREDICTING EXACTLY WHERE ON ANY GIVEN DAY IS BEYOND CURRENT
CAPABILITIES. SPEAKING OF THOSE HIGHS, EXPECT 80S AND 90S THROUGH
NEXT WEEK INTO THE AFTERNOON, AND EXPECT OVERNIGHT LOWS TO REMAIN 5
TO 10 DEGREES ABOVE AVERAGE (SO 60S TO LOW 70S) THANKS TO LINGERING
MOISTURE AND CLOUD COVER.
SEVERE CHANCES REMAIN LOW ON ANY GIVEN DAY GIVEN THE CURRENT
FORECAST, BUT ENOUGH INSTABILITY AND SHEAR WILL BE AROUND FOR THE
OCCASIONAL STRONG STORM THAT COULD BRIEFLY REACH SEVERE LIMITS.
WHILE BENEFICIAL RAINFALL IS ON TAP, MOST OF IT SHOULD BE SPREAD OUT
OVER TIME SUCH THAT FLOODING CHANCES ARE LIMITED (AND MANY OF OUR
LOCAL CREEKS, STREAMS, AND RIVERS ARE RUNNING LOW TO START). AGAIN,
CAN'T RULE OUT AN ISOLATED FLASH FLOODING EVENT, ESPECIALLY IN URBAN
AVIATION
(00Z TAFS)
ISSUED AT 800 PM EDT WED MAY 20 2026
SCATTERED SHRA/TSRA PERSISTS ACROSS PORTIONS OF NORTH GEORGIA,
INCLUDING FTY/PDK/RYY AND AHN. THUNDER CHANCES HAVE COME TO AN END
AT ATL FOR THE EVENING, AND COVERAGE WILL CONTINUE TO DIMINISH
OVER THE NEXT COUPLE OF HOURS. WITH CU AROUND 5 KFT LINGERING
UNDER MID-LEVEL CLOUDS BETWEEN 10-15 KFT, CONDITIONS ARE
ANTICIPATED TO REMAIN LARGELY VFR THROUGH THE OVERNIGHT HOURS.
WITH CALM WINDS OVERNIGHT, PATCHY MVFR CEILINGS AND FOG WILL BE
POSSIBLE EARLY THURSDAY MORNING IN AREAS WHERE SOILS REMAIN WET
FROM TODAY'S RAINFALL. A TEMPO FOR MVFR CONDITIONS HAS BEEN
MAINTAINED FROM 10-13Z. WINDS TOMORROW WILL BE SW/W AT 3-6 KTS,
THOUGH VARIABLE AND GUSTY WINDS WILL BE PRESENT WITH ANY
AFTERNOON STORMS. ANOTHER SCATTERED CU FIELD BETWEEN 3.5-5 KFT
WILL DEVELOP BY 15Z, FOLLOWED BY SCATTERED SHRA/TSRA AFTER 18Z.
CHANCES FOR THUNDERSTORMS APPEARS TO BE HIGHEST ONCE AGAIN IN THE
NORTHERN PART OF THE STATE.
//ATL CONFIDENCE...00Z UPDATE...
MEDIUM CONFIDENCE ON POTENTIAL LOW CEILINGS AND FOG THURSDAY
MORNING.
HIGH CONFIDENCE ON ALL OTHER ELEMENTS.
