SHORT TERM
(THIS AFTERNOON THROUGH TUESDAY)
ISSUED AT 153 PM EDT MON JUL 20 2026
A WARM AND PLEASANT AFTERNOON IS UNDERWAY ACROSS NORTH AND CENTRAL
GA. CURRENT TEMPERATURES ARE IN THE MID 80S TO LOW 90S ACROSS MOST
LOCATIONS OUTSIDE OF THE HIGHER ELEVATIONS IN NORTHEAST GA. ISOLATED
CONVECTION HAS STARTED TO DEVELOP ACROSS FAR NORTH GA AND ALONG THE
HIGHER ELEVATIONS AT THE TIME OF THIS WRITING. THOUGH LATEST HI-RES
GUIDANCE HAS TRENDED DOWNWARD IN COVERAGE WITH NBM ALSO
REFLECTING THIS THEME LARGELY DUE TO A LITTLE BIT MORE DRIER AIR
PRESENT IN THE LOW TO MIDLEVELS. NONETHELESS, THE HIGHEST CHANCES
FOR SHOWERS AND THUNDERSTORMS THROUGH EARLY EVENING WILL BE ACROSS
FAR NORTH GA -- CLOSER TO WHERE A STATIONARY BOUNDARY RESIDES IN
CENTRAL TN -- AND ACROSS PORTIONS OF CENTRAL GA (COLUMBUS TO MACON
TO SWAINSBORO SOUTH) WHERE AN INITIAL AREA OF CONVERGENCE FROM
TROPICAL DEPRESSION TWO LIFTS NORTHWARD LATE THIS AFTERNOON AND
EVENING. CHANCES REMAIN LOW (<15%) FOR AREAS IN AND AROUND THE
I-20/I-85 CORRIDORS.
SPEAKING OF TROPICAL DEPRESSION TWO, LATEST SATELLITE IMAGERY DOES
INDICATE A SLIGHTLY BETTER CENTER BUT STILL CONTINUES TO BE IMPACTED
BY MODERATE SHEAR. VERY SLOW IF ANY MOVEMENT IS EXPECTED THROUGH AT
LEAST THE REST OF TODAY , WITH THE LATEST NHC TRACK INDICATING AN
EVENTUAL WESTWARD TRAJECTORY TOWARDS THE TX COAST IN THE COMING
DAYS. NO DIRECT IMPACTS ARE ANTICIPATED FOR NORTH AND CENTRAL GA.
TUESDAY'S FORECAST WILL BE MORE OR LESS THAN SAME AS TODAY'S
FORECAST. A SHORTWAVE TROUGH WILL BEGIN SWINGING TOWARDS THE GREAT
LAKES REGION DRIVING A SURFACE FRONT THROUGH THE OHIO VALLEY TOWARDS
NORTH GA. A INCREASE SOUTHERLY FLOW ON THE BACK SIDE OF THE WESTWARD
MOVING TROPICAL SYSTEM WILL SUPPORT AFTERNOON SHOWERS AND
THUNDERSTORMS ACROSS CENTRAL GA (MAINLY SOUTH OF I-20) TUESDAY
AFTERNOON. TEMPERATURES WILL ALSO BE A TICK WARMER ON TUESDAY THAN
TODAY WITH HIGHS IN THE 90S AND HEAT INDICES AT OR JUST BELOW 105
(HEAT ADVISORY CRITERIA) IN CENTRAL GA.
LONG TERM
(WEDNESDAY MORNING THROUGH NEXT SUNDAY)
ISSUED AT 153 PM EDT MON JUL 20 2026
ONE FINAL DAY OF WIDESPREAD HEAT INDEX VALUES EXCEEDING 100 IS
EXPECTED BEFORE TEMPERATURES EASE TO SOMETHING A LITTLE MORE
REASONABLE. A COLD FRONT (AND I USE THE WORD 'COLD' LIBERALLY) IS
EXPECTED LATE WEDNESDAY AFTERNOON AND INTO THE OVERNIGHT HOURS OF
THURSDAY. A FEW AREAS IN THE SOUTHERN PART OF THE CWA MAY CONTINUE
TO SEE HI VALUES AS HIGH AS 100 THROUGH THE WEEK. AFTERNOON
THUNDERSTORMS CHANCES INCREASE AS A RESULT, BUT AS OF RIGHT NOW
THERE IS ONLY A MARGINAL CHANCE FOR SEVERE WEATHER AS THE BEST
DYNAMICS REMAIN OFF TO THE NORTHEAST. THE FRONT WILL FILTER IN SOME
DRIER AIR, AND WHILE TEMPS WILL REMAIN IN THE UPPER 80S AND LOWER
90S IT WON'T BE NEARLY AS HUMID.
AFTERNOON THUNDERSTORM ACTIVITY WILL CONTINUE THROUGH THE REST OF
THE WEEK. AS ALWAYS, A FEW STRONG STORMS COULD BE POSSIBLE EACH
AFTERNOON. GUSTY WINDS, FREQUENT LIGHTNING AND SOME LOCALIZED FLASH
FLOODING WILL BE THE MAIN CONCERNS TO WATCH OUT FOR.
WE CONTINUE TO MONITOR THE CURRENT TROPICAL DEPRESSION IN THE GULF,
BUT WE AGREE WITH NHC'S TRACK AND ARE UNLIKELY TO SEE SIGNIFICANT
IMPACTS AS A RESULT THROUGH THE LONG TERM FORECAST PERIOD.
