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

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.

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

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.

Strong storms could hit Monday morning as triple-digit heat indices return

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.

The National Weather Service office in Peachtree City said in a Hazardous Weather Outlook issued at 10:09 p.m. Sunday that the cluster was expected to reach northwest Georgia late Sunday night and continue southeast Monday morning into midday.

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.
