NWS Atlanta: mid-to-late week heat indexes near triple digits again

Wed, 12 Aug 2026 01:20:00 -0400

ATLANTA — The relief window, such as it was, is closing.

The National Weather Service office in Peachtree City is telling north and central Georgia that rising temperatures and increased moisture will make the air feel “quite toasty” this week. The office’s public headline language says many locations will see temperatures creep into the mid-90s through the weekend, and that heat indexes are likely to return to or approach triple-digit values by mid to late week.

Heat index near 100° as NWS keeps storm chances in the daily mix; NOAA flags hottest U.S. July on record

Tue, 11 Aug 2026 01:20:00 -0400

ATLANTA — Tuesday is not a freeze story. It is a water bottle and shade story.

National Weather Service point forecasts for Atlanta grids show a familiar late-summer package: mostly sunny mornings, highs near 91–94°F through the week, heat index values as high as about 99–100°, overnight lows in the mid-70s, and daily chances of showers and thunderstorms that cluster in the afternoon and evening. NWS Atlanta’s public messaging earlier in the week already flagged temperatures trending upward and heat indices likely near triple digits by mid to late week.

NWS Atlanta: temperatures trending up; heat index near triple digits mid to late week

Mon, 10 Aug 2026 01:20:00 -0400

ATLANTA — The coolest part of this August stretch is already behind many neighborhoods.

The National Weather Service office in Peachtree City updated its public graphicast Monday morning with a blunt headline theme: temperatures trending upward. The office said rising temperatures and increased moisture will make things feel quite toasty this week, and that heat indices are likely to return to or near triple-digit values by mid to late week. Forecasters urged people to be mindful of the heat when planning outdoor work or activities.

NWS Atlanta: warming trend, daily storms, triple-digit heat index midweek

Sun, 09 Aug 2026 01:25:00 -0400

ATLANTA — Summer is not done negotiating.

The National Weather Service office in Peachtree City highlighted a familiar late-summer package for north and central Georgia: gradually warming temperatures, continued daily chances for showers and thunderstorms over the next several days, and heat index values likely returning to triple digits by the middle of next week — especially across portions of central Georgia.

Sunday’s working forecast

Point forecasts for Atlanta-area grids on weather.gov late Saturday called for a mostly sunny to partly sunny Sunday with highs near the lower 90s and a chance of afternoon showers and thunderstorms — generally in the 20–40 percent range depending on exact metro location — then a slight chance of storms Sunday night with lows in the low-to-mid 70s. Those percentages are not a guarantee of widespread soaking rain; they are a signal to keep outdoor plans flexible after lunch.

NWS: Thursday storms return; heat-index climb eyed this weekend

Thu, 06 Aug 2026 01:25:00 -0400

ATLANTA — The mid-level low that has owned north Georgia’s afternoons is still spinning, but the longer signal is a hotter, stickier weekend if the Bermuda high wins the tug-of-war.

National Weather Service Peachtree City’s Area Forecast Discussion issued early Wednesday (633 a.m. EDT Aug. 5) kept the key messages simple: scattered showers and thunderstorms again for the afternoon cycle, elevated rainfall rates and slow storm motions supporting localized flash flooding, and diurnally enhanced storm chances continuing through the week with threats for strong winds and heavy rain. Afternoon highs stay within a degree or two of seasonal norms — mid-80s to lower 90s — through the near term.

NWS: Wednesday storms again bring slow movers, flash-flood risk

Wed, 05 Aug 2026 01:15:00 -0400

ATLANTA — The midweek sky still looks like a summer pinwheel: storms that form, stall, and dump hard rain while the severe-wind threat stays mostly on the shelf.

National Weather Service Peachtree City’s Area Forecast Discussion issued at 1:35 a.m. EDT Wednesday, Aug. 5, opened with three key messages: scattered showers and thunderstorms again Wednesday afternoon; elevated rainfall rates and slow storm motions supporting localized flash flooding; and afternoon highs within a degree or two of seasonal normals (mid-80s to lower 90s) through the week.

NWS keeps Tuesday as wetter school-week day across north Georgia

Tue, 04 Aug 2026 05:15:00 -0400

ATLANTA — The first full school commute of the week got the better weather; the follow-up days look wetter.

National Weather Service Peachtree City’s Area Forecast Discussion issued 6:39 a.m. EDT Monday (Aug. 3) kept the short-term theme simple: diurnally enhanced storm chances continue through the end of the week, with temperatures starting slightly cooler than midsummer normals before climbing back toward the mid-90s later in the period. The short-term section warned that slow storm motion and leftover moisture could produce locally heavy rainfall and a patchy flash-flood risk, while any stronger cells might gust 30 to 50 mph even if overall instability stays limited.

NWS: Sunny start, then afternoon storm chances Monday across metro Atlanta

Mon, 03 Aug 2026 05:10:00 -0400

ATLANTA — After a wet weekend on the National Weather Service calendars, Monday looks like a classic late-summer split: sun and humidity early, then a renewed shot at afternoon storms.

The NWS point forecast for a location just east-southeast of downtown Atlanta, updated early Aug. 2 and still the operative public grid into Monday, called for Monday to trend mostly sunny with a high near 87°F and a 30 percent chance of showers and thunderstorms, mainly after 4 p.m. West winds were forecast to increase from light to 5–10 mph in the morning, with gusts as high as 15 mph. Monday night carried the same 30 percent storm chance before 8 p.m., then a low around 71°F under partly cloudy skies.

Sun, 26 Jul 2026 22:20:00 -0400

ATLANTA — A cluster of thunderstorms could bring damaging winds, heavy rain and frequent lightning to north and central Georgia on Monday morning before dangerous heat builds across the region again.

A few storms could become strong or severe. The primary threats Monday are damaging winds, locally heavy rainfall and frequent lightning, according to the outlook.

NWS Atlanta lifts metro Heat Advisory but keeps eastern Georgia warning as afternoon storms roll in Thursday

Thu, 23 Jul 2026 05:40:00 -0400

NWS Atlanta said the lingering advisory area will combine high humidity with afternoon highs in the upper 90s to push apparent temperatures well above the actual air temperature.

The NWS Hazardous Weather Outlook for the region had flagged scattered thunderstorms capable of producing gusty to locally damaging winds, locally heavy rainfall and frequent lightning through the afternoon and evening hours. By early evening, the strongest cells had moved across the metro and pushed east, but the Weather Impact Team cautioned that additional scattered storms could develop into the overnight period.

North Georgia is in for a soggy stretch of weather, and Atlanta News First has declared a First Alert Weather Day for Tuesday as another round of heavy rain and thunderstorms moves into the region.

Scattered thunderstorms that developed across the metro on Monday are expected to linger well into the overnight hours, with the bigger concern being flash flooding. Slow-moving storm clusters could drop 2 to 4 inches of rain in isolated spots, according to the Atlanta News First forecast team.

Mon, 13 Jul 2026 07:30:00 -0400

A wet weather pattern will keep Atlanta cooler than normal through midweek, with scattered showers and thunderstorms expected each afternoon through Wednesday.

Highs will stay in the low 80s — several degrees below normal for mid-July — before the heat builds back into the low 90s by Friday.

“Heat concerns will take a brief break,” said FOX 5 Atlanta chief meteorologist Joanne Feldman. “But the humidity stays high, so it will still feel pretty muggy.”

Heat advisory extended through Saturday as heat index tops 108 again

Fri, 10 Jul 2026 11:00:00 -0400

The National Weather Service extended a heat advisory across north and central Georgia through 8 p.m. Saturday as heat index values are forecast to climb back into dangerous territory.

Forecasters expect actual air temperatures in the mid-90s combined with high humidity to push feels-like readings past 108 degrees in some areas, including downtown Atlanta and the south metro.

“Hazardous heat is possible, especially for vulnerable populations,” the weather service said. “Stay hydrated, stay in air-conditioned rooms, stay out of the sun, and check up on relatives and neighbors.”

Atlanta weather: brief relief midweek before heat returns for holiday weekend

Tue, 07 Jul 2026 12:00:00 -0400

A weak cold front pushed through north Georgia overnight Monday, bringing scattered thunderstorms and a brief reprieve from the heat that has gripped the region for the past week.

Tuesday’s forecast calls for highs in the upper 80s — still warm, but noticeably cooler than the upper 90s and heat index values above 105 that defined much of the past week.

“Drier air is moving in behind the front, which will knock down humidity a bit and make it feel much more comfortable,” said NWS Atlanta forecaster Andrew Dessler. “It’s not a true cold front, but it will feel like one after what we’ve been through.”

Atlanta weather: hot and humid Monday before midweek storms bring relief

Monday’s forecast calls for highs in the mid-90s with heat index values around 100 degrees. The National Weather Service has not issued a heat advisory, but city cooling centers remain open.

A cold front pushing in from the northwest will bring scattered thunderstorms Tuesday afternoon and evening. Some of the storms could be strong, with damaging winds and heavy rain the main threats.

Scattered thunderstorms are possible in the afternoon, but the Storm Prediction Center has most of north Georgia in a marginal risk category.
