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…
