SHORT TERM
(TODAY THROUGH SUNDAY)
ISSUED AT 249 AM EDT SAT AUG 8 2026
OVERALL CLEAR SKIES THIS MORNING SHOULD CONTINUE UNTIL JUST AFTER
SUNRISE WHEN A FEW LOWER LEVEL CLOUDS FILTER IN. SHOULD SEE A
CUMULUS FIELD OVER THE NORTHERN HALF OF THE AREA AT LEAST WHICH IS
WHERE WE'RE LIKELY TO SEE SCATTERED SHOWERS AND THUNDERSTORMS
THROUGH SUNSET. PATTERN AS A WHOLE MOSTLY STAYS THE SAME THROUGH
SUNDAY WITH THE AREA IN BETWEEN TWO AREAS OF HIGH PRESSURE, THOUGH
HIGH PRESSURE DOES BEGIN BUILDING MORE INTO OUR AREA WHICH WILL IN
TURN HELP RAISE TEMPERATURES AND DEWPOINTS. FOR TODAY, THE
SCATTERED COVERAGE WILL BE SUPPORTED BY CAPE VALUES (1000-1500
J/KG) BUT WITH LITTLE SHEAR, EXPECTING IT TO BE POP UP IN NATURE
WITH THE MAIN THREATS BEING GUSTY WINDS AND FREQUENT LIGHTNING.
PWATS ARE FORECAST TO BE A BIT LOWER TODAY AT 1.5-1.6" SO THE
FLOODING THREAT DUE TO HEAVY RAIN RATES WILL BE LOWER TODAY.
PUSHING INTO TOMORROW, THE ENVIRONMENT MOISTENS UP A BIT WITH
DEWPOINTS IN THE MID 70S ACROSS MUCH OF THE AREA. THIS ALONG WITH
CAPE VALUES CLOSER TO 2000-2500 J/KG WILL BE SUPPORTIVE OF MORE OF
A SEVERE THREAT OVER NORTHERN GEORGIA. CURRENT SPC OUTLOOK HAS
NORTHEAST GEORGIA WITHIN A MARGINAL RISK FOR SEVERE STORMS BUT
OVERALL THERE ISN'T TOO MUCH OF A DIFFERENCE IN ENVIRONMENT FROM
THAT AREA TO FURTHER WEST. WITH THIS IN MIND, STORMS TOMORROW WILL
BE CAPABLE OF PRODUCING ISOLATED DAMAGING WIND GUSTS. WITH
SLIGHTLY HIGHER PWATS TOMORROW, WATERLOGGED DOWNDRAFTS WILL ALSO
BE POSSIBLE LIKE WE'VE SEEN IN WEEKS PAST.
LONG TERM
(SUNDAY NIGHT THROUGH FRIDAY)
ISSUED AT 249 AM EDT SAT AUG 8 2026
TYPICAL SUMMERTIME CONVECTION PATTERN WITH TRIPLE DIGIT HEAT INDEX
VALUES WILL CONTINUE NEXT WEEK. CONDITIONS ARE EXPECTED TO FLIRT
WITH HEAT ADVISORY CRITERIA THROUGH THE WEEK, THOUGH IF AN ADVISORY
IS NEEDED IT WILL MOSTLY LIKELY BE IN THE SE PORTION OF THE CWA.
FORTUNATELY, THUNDERSTORMS WILL BE EXPECTED EACH AFTERNOON WHICH MAY
HELP EASE TEMPERATURES DURING PEAK HEATING. THERE IS PRETTY GOOD
AGREEMENT THAT AFTERNOON CONVECTION WILL FORM EVERYDAY FOR THE
FORESEEABLE FUTURE, THOUGH NO STRONG SIGNAL FOR SEVERE WEATHER
EXISTS WITH THE LIMITED SHEAR IN PLACE. STRENGTH OF STORMS WILL
ULTIMATELY DEPEND ON HEATING.
