SHORT TERM
(TODAY THROUGH SUNDAY)
ISSUED AT 233 AM EDT SAT JUN 20 2026
A FRONTAL BOUNDARY HAS STALLED OUT JUST SOUTH OF THE I-20
CORRIDOR, CREATING A SHARP MOISTURE GRADIENT ACROSS OUR AREA
TODAY. NORTH OF THE BOUNDARY, WHICH INCLUDES MOST OF THE ATLANTA
METRO, TODAY WILL BE MOSTLY DRY WITH ONLY A FEW SHOWERS OR WEAK
STORMS AROUND DURING THE AFTERNOON. LOWER DEWPOINTS IN THIS AREA
WILL MAKE IT FEEL LESS HUMID THAN RECENT DAYS, WITH HIGHS TOPPING
OUT IN THE UPPER 80S. FOR AREAS SOUTH OF THE BOUNDARY
(CENTRAL/SOUTHERN GA), THE WARM AND HUMID AIRMASS WILL PERSIST,
SUPPORTING SCATTERED TO NUMEROUS SHOWERS AND STORMS FROM LATE
MORNING THROUGH THE EVENING HOURS. A FEW STORMS COULD BE STRONG,
WITH GUSTY WINDS, FREQUENT LIGHTNING, AND HEAVY RAINFALL. WE WILL
HAVE TO WATCH OUT FOR LOCALIZED FLASH FLOODING, ESPECIALLY IF
AREAS HIT HARD IN RECENT DAYS ARE HIT AGAIN. TEMPERATURES WILL
RISE INTO THE MID TO UPPER 80S, WITH HEAT INDEX VALUES PEAKING IN
THE MID TO UPPER 90S.
ON SUNDAY, LOW TO MID LEVEL WINDS OVER THE REGION WILL INCREASE
OUT OF THE SOUTHWEST IN RESPONSE TO A SYSTEM OVER THE MIDWEST,
PUSHING THE FRONTAL BOUNDARY BACK NORTH OUT OF OUR AREA. THE WARM
AND HUMID AIRMASS WILL SPREAD BACK NORTH ACROSS ALL OF NORTH AND
CENTRAL GA, RESULTING IN HIGH TEMPS IN THE UPPER 80S TO LOW 90S
AND HEAT INDEX VALUES IN THE MID TO UPPER 90S. SUBTLE MID-LEVEL
RIDGING WILL TRY TO KEEP A LID ON CONVECTION, BUT ISOLATED TO
SCATTERED SHOWERS AND STORMS WILL STILL BREAK THROUGH DURING THE
AFTERNOON AND EVENING.
LONG TERM
(SUNDAY NIGHT THROUGH FRIDAY)
ISSUED AT 233 AM EDT SAT JUN 20 2026
TO BEGIN THE PERIOD, UPPER LEVEL HIGH PRESSURE WILL BE SITUATED
THE SOUTH OF THE REGION WITH NW FLOW ALOFT. THIS WILL SET THE
STAGE FOR AN UNSETTLED WEATHER PATTERN WITH SUMMER AFTERNOON
CONVECTION LIKELY MOST DAYS IN THE LONG TERM PERIOD.
LOW END RAIN CHANCES WILL BE POSSIBLE EACH AFTERNOON NEXT WEEK AS
RIDGING BUILDS IN TO THE SOUTH. THIS WILL PROMOTE MORE HUMID
CONDITIONS ACROSS THE STATE, WITH A SUMMER-LIKE PATTERN LIKELY
THIS UPCOMING WEEK. AFTERNOON CONVECTION WILL BE POSSIBLE EACH
DAY, WITH AFTERNOON RAIN CHANCES AROUND 30-40 PERCENT. COVERAGE
WOULD NOT BE WIDESPREAD BUT MORE SCATTERED AND STRONG TO SEVERE
STORMS POSSIBLE.
TEMPERATURES ARE EXPECTED TO BE AVERAGE TO SLIGHTLY ABOVE AVERAGE
AS HIGH PRESSURE SETTLES SOUTH OF THE STATE. MAX HEAT INDEX
VALUES WILL RETURN TO THE UPPER 90S TO NEAR 100 DEGREES FOR
CENTRAL AND SOUTHERN LOCATIONS.
