Atlanta is starting Monday, August 10, with clear skies, temperatures around 75°F and air that already feels muggy. The calm morning is a brief intermission: temperatures are expected to climb to 92°F, with a heat index near 99°F, before showers and thunderstorms become possible this afternoon. For people planning errands, outdoor work or a patio lunch, the best weather window is the first half of the day.
Afternoon Storms Could Crash Into Plans
The National Weather Service in Peachtree City says a shower could pop up between 1 and 2 p.m., with the storm chance increasing from 2 to 5 p.m. and lingering into the evening. The forecast puts the chance of rain at 50%, and any storm could bring a quick heavy downpour or gusty wind. No watches, warnings or advisories are listed for Atlanta this morning, but lightning is still a reason to head indoors when thunder rolls.
Winds will stay light, generally from the southwest at 0 to 5 mph during the day. Monday night should turn partly cloudy with a low around 74°F, although a 40% chance of showers and thunderstorms remains in place before 8 p.m. The heat index could still reach 97°F Monday evening, so the air may not feel especially refreshed after sunset.
Heat Takes Over Later This Week
Tuesday and Wednesday keep the 92°F highs, with afternoon storm chances of 30% and heat index values near 100°F Tuesday. Thursday through Sunday look hotter and mostly sunnier, with highs of 93°F Thursday, 94°F Friday, 95°F Saturday and 94°F Sunday. A few late-day storms remain possible Saturday and Sunday, but the broader story is a hotter stretch for metro Atlanta.
That combination of heat, humidity and pop-up storms can turn a routine walk or work shift into a draining one. Drink water before heading out, take breaks in shade or air conditioning, and avoid waiting out thunderstorms under trees or near open fields. Keep an eye on updated forecasts if you have outdoor plans, especially during the afternoon storm window.
