SHORT TERM
(TODAY THROUGH TUESDAY)
ISSUED AT 308 AM EDT MON JUN 29 2026
THE SHORT TERM PERIOD WILL BE CHARACTERIZED BY AN UPPER LEVEL RIDGE
CONTINUING TO AMPLIFY AND SPREAD EASTWARD OVER THE REGION. AT THE
500 MB LEVEL, THE RIDGE WILL BE BETWEEN 595-600 DAM, WHICH IS CLOSE
TO 2 STANDARD DEVIATIONS ABOVE NORMAL FOR THIS TIME OF THE YEAR.
TEMPERATURES WILL CONTINUE THEIR CLIMB UNDER THIS RIDGE. LOWS THIS
MORNING WILL START THE MORNING IN THE MID TO UPPER 70S ACROSS THE
MAJORITY OF THE AREA. HIGH TEMPERATURES THIS AFTERNOON WILL RISE
INTO THE MID TO UPPER 90S, WITH SLIGHTLY LOWER VALUES IN THE FAR
NORTHEAST MOUNTAINS. DEWPOINTS REMAINING IN THE LOW TO MID 70S WILL
COMBINE WITH THESE HOT AFTERNOON TEMPERATURES AND LEAD TO HEAT INDEX
VALUES IN THE MID 100S EVERYWHERE EXCEPT THE FAR NORTHERN TIER OF
THE STATE. LOCATIONS IN EAST-CENTRAL GEORGIA WILL FURTHERMORE SEE
HEAT INDICES IN THE UPPER 100S AND APPROACHING 110 DEGREES IN THE
PEAK HEATING HOURS. AS SUCH, ANOTHER HEAT ADVISORY IS IN EFFECT FROM
12 PM TO 8 PM EDT TODAY, THIS TIME FOR AN AREA ALONG AND SOUTH OF A
ROUGH LINE FROM ROME TO CANTON TO GAINESVILLE. THOSE PLANNING TO
SPEND TIME OUTDOORS SHOULD TAKE NECESSARY PRECAUTIONS, DRINK PLENTY
OF FLUIDS, AND TAKE FREQUENT BREAKS IN THE SHADE AND AIR
CONDITIONING.
WITH THE AXIS OF THE OF THE AFOREMENTIONED RIDGE CENTERED OVER
ALABAMA TODAY, WEAK SHORTWAVE DISTURBANCES ARE EXPECTED TO CONTINUE
TRAVERSING THE EASTERN PERIPHERY OF THE RIDGE, MOVING FROM EASTERN
TENNESSEE TOWARDS THE GEORGIA/SOUTH CAROLINA COAST. AS A RESULT,
SCATTERED THUNDERSTORMS ARE FORECAST TO DEVELOP OVER FAR NORTHEAST
GEORGIA BY MID-AFTERNOON, SPREADING SOUTH THROUGH EASTERN GEORGIA
THROUGH THE EVENING. POPS ARE AT MOST 30-40% IN THE EASTERN FRINGE
OF THE FORECAST AREA, WITH LESSER CHANCES TO THE WEST. UNCERTAINTY
IN POPS INCREASES LATER IN THE EVENING CONSIDERING DOWNSTREAM
EVOLUTION OF THUNDERSTORMS AS THEY PROPAGATE SOUTH. STORMS THAT
DEVELOP WILL BE CAPABLE OF PRODUCING FREQUENT LIGHTNING, HEAVY
RAINFALL, AND GUSTY WINDS, THOUGH WIDESPREAD AND ORGANIZED SEVERE
WEATHER IS NOT EXPECTED.
THE HIGH PRESSURE REGIME WILL CONTINUE ON TUESDAY, WITH
CONDITIONS EXPECTED TO BE SIMILAR TO TODAY. LOW TEMPERATURES IN
THE MID TO UPPER 70S ONCE AGAIN WILL NOT PROVIDE SUBSTANTIAL
RELIEF FROM THE HOT CONDITIONS DURING THE DAY. HIGH TEMPERATURES
AND HEAT INDICES ON TUESDAY WILL BE IN THE MID 90S AND MID 100S
RESPECTIVELY ACROSS ALL BUT THE FAR NORTHERN TIER, WHICH WILL
LIKELY WARRANT ANOTHER HEAT ADVISORY ON TUESDAY. WITH THE AXIS OF
THE RIDGE SHIFTING FURTHER TO THE EAST, AFTERNOON THUNDERSTORMS
WILL BE MORE DIURNALLY-DRIVEN IN NATURE COMPARED TO TODAY.
LONG TERM
(TUESDAY NIGHT THROUGH SUNDAY)
ISSUED AT 308 AM EDT MON JUN 29 2026
THE CENTER OF THE MID-LEVEL RIDGE WILL BE OVER THE OHIO AND
TENNESSEE VALLEYS LATE TUESDAY, EXPECTED TO GRADUALLY SHIFT EAST
AS WE HEAD INTO THE HOLIDAY WEEKEND. THIS PATTEN WILL KEEP
ELEVATED TEMPERATURES AND HEAT INDEX VALUES IN THE FORECAST WITH
ABOVE NORMAL HIGHS AND LOWS EACH DAY. AFTERNOON TEMPERATURES TOP
OUT IN THE MID TO UPPER 90S FOR MOST LOCATIONS, WITH A FEW SPOTS
CREEPING INTO THE TRIPLE DIGITS LATE WEEK INTO INDEPENDENCE DAY.
WITH DEWPOINTS IN UPPER 60S TO MID 70S DURING THE DAY, HEAT
INDICES WILL BE OVER 100 DEGREES THROUGHOUT THE ENTIRE LONG TERM
FORECAST. MORE HEAT PRODUCTS ARE LIKELY TO COME THROUGH THE WEEK
AS SOME LOCATIONS SEE HEAT INDEX VALUES EXCEED 105 DEGREES. AS FOR
LOWS, A FEW LOCATIONS MAY APPROACH RECORD HIGH MINIMUMS AS WE
BOTTOM OUT IN THE MID OR EVEN UPPER 70S FOR MANY AREAS.
DAILY LOW RAIN CHANCES ARE ALSO SEEN AS DISTURBANCES ROUND THE
CENTER OF THE HIGH PRESSURE TO THE NORTH OF THE FORECAST AREA. ONLY
ISOLATED TO SCATTERED SHOWERS OR NON-SEVERE THUNDERSTORMS ARE
EXPECTED AT THIS TIME GIVEN THE UPPER LEVEL PATTERN.
AVIATION
(12Z TAFS)
ISSUED AT 629 AM EDT MON JUN 29 2026

CLEAR SKIES. A CU FIELD BETWEEN 040-050 IS EXPECTED TO DEVELOP BY

FORECAST ACROSS EAST GA IN THE MID AFTERNOON INTO THE EVENING,
SPREADING FROM NORTH TO SOUTH. WITH CHANCES FOR STORMS TRENDING
