SHORT TERM
(TODAY THROUGH THURSDAY)
ISSUED AT 306 AM EDT WED AUG 12 2026
LINE OF SHOWERS AND EMBEDDED THUNDERSTORMS CONTINUE ACROSS
NORTHERN GEORGIA. AS THEY PUSH SOUTH, WILL CONTINUE TO SEE A
WEAKENING TREND BEFORE DISSIPATING IN THE NEXT COUPLE OF HOURS.
THE NORTHWEST FLOW PATTERN CONTINUES INTO THE DAY TODAY WHERE WE
ARE LIKELY TO SEE ISOLATED TO SCATTERED THUNDERSTORMS POP UP
ACROSS NORTH AND CENTRAL GEORGIA AGAIN. WHAT WE'LL BE KEEPING AN
EYE ON WILL BE ANY POTENTIAL MCS THAT IS ABLE TO PUSH INTO NORTH
GEORGIA TOMORROW. CAMS CONTINUE TO BE A BIT ALL OVER THE PLACE
WHEN IT COMES TO TIMING BUT DEFINITELY EYEING TOMORROW EVENING
INTO THE OVERNIGHT AS THE BEST POSSIBLE TIMING AS A LINE MOVES IN
FROM THE NORTH. MAIN THREATS WILL CONTINUE TO BE STRONG TO LOCALLY
DAMAGING WIND GUSTS (40-60MPH), FREQUENT RAINFALL, AND LOCALLY
HEAVY RAINFALL THAT COULD LEAD TO FLOODING CONCERNS.
WHEN IT COMES TO TEMPERATURES THE NEXT TWO DAYS, WILL SEE HIGHS
GET INTO THE LOW TO MID 90S ACROSS THE AREA. ALTHOUGH DEWPOINTS
WERE LOWERED A TAD TO REFLECT THE MIXING THAT IS LIKELY TO OCCUR,
HEAT INDEX VALUES STILL TOP OUT CLOSE TO 105 IN SOME AREAS OF
CENTRAL GEORGIA.
LONG TERM
(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 306 AM EDT WED AUG 12 2026
THE LONG-TERM OUTLOOK CONSISTS OF A STRENGTHENING RIDGE THAT WILL
BUILD THROUGH THE WEEKEND. MODELS DEPICT AN INCREMENTAL DECREASE IN
PRECIPITATION BY THE TIME WE REACH THE WEEKEND; HOWEVER, THEY TEND
TO UNDERSELL THE EFFECTS OF A PERSISTENT NW FLOW AND ASSOCIATED MCS
DEVELOPMENTS THAT ARE COMMON IN THESE ENVIRONMENTS. THAT BEING
THE CASE, THERE IS AT LEAST A CHANCE OF SEEING A MORE ACTIVE
DIURNAL CONVECTIVE PATTERN EVEN AS TEMPERATURES CLIMB IN RESPONSE
TO THE BUILDING RIDGE. ONE POSSIBLE SILVER LINING IS THAT, IF
CONVECTION IS MORE ACTIVE THAN EXPECTED, WE WILL LIKELY SEE
SLIGHTLY LOWER AFTERNOON TEMPERATURES THROUGH THE WEEKEND.
REGARDLESS, THE RISK OF EXCESSIVE HEAT WILL RAMP UP EACH DAY,
WITH SOME AREAS REACHING THE MID-TO-UPPER 90S BY FRIDAY. MOST OF
THE CWA CAN EXPECT APPARENT TEMPERATURES IN THE TRIPLE DIGITS,
WITH THE CENTRAL AND EASTERN PORTIONS OF THE FORECAST AREA
REACHING HEAT ADVISORY CRITERIA. WE WILL NEED TO KEEP AN EYE ON
TEMPERATURES OVER THE PERIOD, AND THE HEAT SHOULD BE A
CONSIDERATION WHEN MAKING PLANS FOR OUTDOOR ACTIVITIES.
AVIATION

ISSUED AT 1218 PM EDT WED AUG 12 2026
SOME ISOLATED STORMS BEGINNING TO POP ACROSS WESTERN AND SOUTHERN

AFTER SUNSET WITH ANOTHER ROUND OF STORMS EXPECTED AGAIN THU
AFTERNOON/EVENING. WINDS MAINLY OUT OF THE W-NW IN THE 5-10KT
RANGE. WILL SEE GUST IN THE 15-25KT RANGE IN AND AROUND
CONVECTION. VSBYS AND CEILINGS ARE IN THE VFR RANGE BUT WILL SEE
