SHORT TERM
(TODAY THROUGH MONDAY)
ISSUED AT 302 AM EDT SUN JUN 28 2026
AN UPPER LEVEL RIDGE CURRENTLY CENTERED OVER THE MISSISSIPPI RIVER
VALLEY WILL AMPLIFY AND CONTINUE EASTWARD TODAY, SETTING UP OVER THE
EASTERN CONUS THROUGH THE REMAINDER OF THE SHORT TERM PERIOD. AS THE
RIDGE BUILDS, TEMPERATURES WILL CONTINUE TO CLIMB ACROSS THE AREA.
LOW TEMPERATURES THIS MORNING WILL BEGIN IN THE LOW TO MID 70S
ACROSS THE MAJORITY OF NORTH AND CENTRAL GEORGIA. WITH PERSISTENT
SOUTHWESTERLY LOW LEVEL FLOW AND DEEP GULF MOISTURE IN PLACE, THESE
LOWS WILL CLOSELY REFLECT DEWPOINTS. HIGH TEMPERATURES THIS
AFTERNOON WILL RISE INTO THE LOW 90S IN NORTHWEST GEORGIA AND 80S IN
THE MOUNTAINS AND WILL RISE INTO THE MID 90S ELSEWHERE ACROSS THE
AREA. THE COMBINATION OF THESE TEMPERATURES AND DEWPOINTS WILL CAUSE
DEWPOINTS TO RISE INTO THE UPPER 90S TO MID 100S IN THE PEAK HEATING
HOURS. A HEAT ADVISORY HAS BEEN ISSUED IN PORTIONS OF EAST-CENTRAL
GEORGIA THIS AFTERNOON FROM 12 PM TO 8 PM THIS EVENING. HERE, HEAT
INDICES ARE MOST LIKELY TO REACH 105 DEGREES THIS AFTERNOON. THOSE
PLANNING TO SPEND TIME OUTDOORS SHOULD DRINK PLENTY OF FLUIDS AND
TAKE PLENTY OF BREAKS IN THE SHADE AND AIR-CONDITIONING.
DIURNALLY-DRIVEN CONVECTION IS EXPECTED ACROSS FAR NORTH GEORGIA
THIS AFTERNOON, WITH CHANCES OF 10% CHANCES OR LESS TO THE SOUTH OF
I-20. AS A WEAKENING SHORTWAVE CONTINUES TRAVERSES THE EASTERN
PERIPHERY OF THE RIDGE AND TOWARDS SOUTH CAROLINA, ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS WILL SPREAD ACROSS EASTERN
GEORGIA OVERNIGHT. TEMPERATURES WILL BE WARMER STILL ON MONDAY,
WHICH WILL LEAD TO HEAT INDEX VALUES IN THE MID 100S IN NORTH
GEORGIA (WITH THE EXCEPTION OF THE MOUNTAINS) AND UPPER 100S IN
CENTRAL GEORGIA. ANOTHER HEAT ADVISORY IS EXPECTED ON MONDAY, THIS
TIME ACROSS THE MAJORITY OF THE FORECAST AREA. SPORADIC RELIEF FROM
THE HEAT COULD COME IN THE FORM OF SCATTERED AFTERNOON
THUNDERSTORMS, MOST LIKELY ACROSS THE EASTERN HALF OF THE AREA ON
SUNDAY AFTERNOON. WITH STRONG INSTABILITY, STORMS THAT DEVELOP WILL
BE CAPABLE OF PRODUCING FREQUENT LIGHTNING, HEAVY RAIN, AND GUSTY
WINDS.
LONG TERM
(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 302 AM EDT SUN JUN 28 2026
UPPER RIDGING WILL BUILD OVER THE EASTERN US THROUGH MUCH OF THE
WEEK, WITH THE CENTER OF THE RIDGE EXPECTED TO MIGRATE FROM THE
LOWER MS VALLEY EARLY IN THE WEEK INTO THE CAROLINAS/MID-ATLANTIC BY
THE END OF THE WEEK. WITH THE RIDGE IN CLOSE PROXIMITY, HOT
TEMPERATURES WILL PERSIST OVER THE REGION THROUGH THE PERIOD, WITH
HIGHS IN THE MID TO UPPER 90S FOR MOST AREAS OUTSIDE THE HIGHER
TERRAIN OF NORTHEAST GA. COMBINED WITH INCREASING HUMIDITY, HEAT
INDEX VALUES OVER 100 WILL BE COMMON MOST AFTERNOONS, WITH VALUES
OVER 105 DEGREES POSSIBLE IN SOME AREAS. THESE TEMPERATURES WILL
LEAD TO INCREASED RISK FOR HEAT ILLNESS FOR THOSE SPENDING EXTENDED
PERIODS OUTDOORS, WITH LOWS IN THE MID TO UPPER 70S OFFERING LITTLE
OVERNIGHT RELIEF.
THE CLOSE PROXIMITY OF THE UPPER RIDGE WILL LIKELY ACT TO SUPPRESS
CONVECTION MOST AFTERNOONS, BUT CAN'T COMPLETELY RULE OUT A FEW
STORMS THROUGH THE WEEK GIVEN HIGH LEVELS OF MOISTURE AND
INSTABILITY.
