Saturday, June 27, 2026, is starting sticky in Atlanta, with mostly cloudy skies, mid 70s on the thermometer, and humidity hovering near 90 percent. By this afternoon, highs climb into the low 90s, and it will feel closer to the upper 90s once you factor in the heat index. Expect some decent sunshine around midday, with just a slight chance of late day showers or thunderstorms after about 2 p.m.
Afternoon Storm Chances
That storm chance stays on the low side, around 20 percent after about 2 p.m., and it is most likely to materialize north of I 20 and into far north Georgia. Forecasters at the National Weather Service in Peachtree City have outlined a Marginal Risk for a few strong storms well to the north and northeast, where isolated damaging wind gusts and heavy downpours are on the table. For most of metro Atlanta, any storms should be spotty. If you have evening outdoor plans, keep an eye on the radar and be ready to duck inside for brief heavy rain and frequent lightning.
Heat Through Early Next Week
The bigger story is the heat, which builds into early next week. Highs will generally sit in the low to mid 90s, with a few afternoons edging toward the mid 90s. The National Weather Service notes that heat index values could reach near or above 100 beginning Sunday, and some inland spots may push 105 degrees or higher at times. If those numbers verify, a Heat Advisory could follow. Common sense still works: drink plenty of water, avoid strenuous outdoor work in the hottest part of the afternoon, and check on older neighbors and anyone without reliable air conditioning.
Where To Cool Down
For anyone who needs a break from the heat, the city posts cooling center openings and related guidance. Check the City of Atlanta cooling center information page or call 311 for the latest local options. Otherwise, lean on air conditioned transit when you can, avoid the midday sun from roughly 11 a.m. to 4 p.m., carry water, and shift strenuous outdoor plans to the cooler morning or evening hours.
