THREATS BEING GUSTY WINDS, LOCALLY HEAVY RAINFALL, AND
FREQUENT LIGHTNING.

SHORT TERM
(TODAY THROUGH TUESDAY)
ISSUED AT 558 AM EDT MON JUL 27 2026
SCATTERED SHOWERS ACROSS NORTHERN GEORGIA THIS MORNING WILL
EVENTUALLY GIVE WAY TO A PLEASANT AFTERNOON. A FEW THUNDERSTORMS
WILL BE POSSIBLE, BUT THE THREAT OF AN MCS HAS SHIFTED WESTWARDS AND
OUT OF THE CWA. THAT BEING SAID A FEW STORMS COULD CREATE SOME GUSTY
WINDS AND PLENTY OF LIGHTNING BUT THE OVERALL SEVERE THREAT REMAINS
LOW AT THIS TIME.
HOT AND HUMID CONDITIONS WILL START THE WORK WEEK OFF. THE FLOW WILL
REMAIN GENERALLY OUT OF THE NORTHWEST THROUGH THE SHORT TERM. WARM
TEMPS AND MOSTLY SUNNY SKIES WILL BUILD ENOUGH ENERGY TO SUPPORT AN
MCS THAT FOLLOWS THE RIDGE DOWN OUT OF THE MIDWEST. DEPENDING ON
WHICH MODEL YOU LOOK AT, THERE SEEMS TO BE AN INDICATION THAT AN MCS
IS POSSIBLE EVERY DAY THROUGH AT LEAST TUESDAY AND POSSIBLY INTO THE
LONG TERM.
IT'S A TRICKY FORECAST, AS THESE STORMS ARE TOUGH TO FORECAST. THE
OVERALL THEME THOUGH IS THAT THEY LOOSE MUCH OF THEIR STEAM ALONG
THE TN/GA BORDER. WE'LL CONTINUE TO KEEP A CLOSE EYE ON THE STORM
TRACKS AND DO OUR BEST TO MINIMIZE THE UNCERTAINTY IN THE
FORECAST.
LONG TERM
(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 558 AM EDT MON JUL 27 2026
AS THE LONG TERM PERIOD BEGINS, A VERTICALLY STACKED LOW PRESSURE
SYSTEM WILL BE CENTERED OVER NEW YORK WITH AN ASSOCIATED COLD FRONT
PUSHING INTO NORTH GEORGIA. A LINE OF SHOWERS AND THUNDERSTORMS
GENERATED ALONG THE FRONT IS ANTICIPATED TO BE MOVING SOUTHWARD
THROUGH THE FORECAST AREA, THOUGH AS IS THE CASE WITH THESE
NORTHWESTERLY FLOW MCSS, THERE REMAINS UNCERTAINTY WITH THE MOVEMENT
AND EVOLUTION OF THESE STORMS. A FEW OF THESE STORMS MAY BE STRONG
AND CAPABLE OF PRODUCING GUSTY WINDS, THOUGH THE SEVERE WEATHER
THREAT WILL DIMINISH THROUGH THE EVENING WITH THE LOSS OF DIURNAL
INSTABILITY. SHOWERS AND THUNDERSTORMS WILL DEVELOP SOUTH OF THE
FRONT ONCE AGAIN ON WEDNESDAY AFTERNOON AS IT CONTINUES THROUGH
CENTRAL GEORGIA. HIGH TEMPERATURES ON WEDNESDAY AFTERNOON WILL BE IN
THE MID 80S TO NEAR 90 IN AREAS NORTH OF I-85 BUT STILL CLIMB INTO
THE MID 90S IN CENTRAL GEORGIA BEFORE THE FRONT ARRIVES.
BY WEDNESDAY NIGHT, THE FRONT WILL HAVE CLEARED THE AREA TO THE
SOUTH. WHICH WILL BE NOTICEABLE WITH DEWPOINTS DECREASING INTO THE
60S ACROSS THE AREA ON THURSDAY AND FRIDAY. LOW TEMPERATURES ON EACH
OF THESE DAYS WILL RANGE FROM THE LOW 60S IN THE FAR NORTHEASTERN
MOUNTAINS TO THE LOW 70S IN EAST-CENTRAL GEORGIA. HIGH TEMPERATURES
WILL BE IN THE MID TO UPPER 80S TO THE NORTH OF I-85 AND LOW TO MID
90S TO THE SOUTH. THIS DRY PATTERN WILL LARGELY INHIBIT POPS ON
THURSDAY AND FRIDAY, THOUGH AN ISOLATED THUNDERSTORM IN THE FAR
SOUTHERN TIER CANNOT BE RULED OUT IN THE VICINITY OF THE FRONTAL
BOUNDARY STALLED IN SOUTH GEORGIA.
