Atlanta, Georgia – Sweltering summer heat and a rolling chance of thunderstorms will dominate Atlanta’s weather pattern through Thursday, prompting caution for those headed outdoors or traveling across metro highways. Afternoon heat indexes could push near 100° today, while pop-up storms may create hazardous road conditions and localized flooding.
According to the National Weather Service, showers and thunderstorms are likely each afternoon and evening through Thursday, with storm chances peaking at 50% Wednesday and Thursday nights. Areas around I-285 and I-20 may see reduced visibility, slick roads, and ponding during downpours, especially after 3 p.m. daily.
Communities in Fulton, DeKalb, and Gwinnett counties can expect highs between 88° and 95° this week, with overnight lows in the low-to-mid 70s. Afternoon plans—especially outdoor sports, festivals, or commutes—could be disrupted by sudden lightning and gusty winds. Residents are urged to stay weather-aware, use caution on wet roads, and avoid flooded areas. Power outages and delays in MARTA transit service are possible if storms intensify.
If you must be outside, stay hydrated, limit strenuous activity during peak heat, and charge devices ahead of possible outages. This pattern echoes Atlanta’s classic summer setup—brief sun, high humidity, and fast-moving storms.
Storm chances remain elevated through Friday night before the area dries out for the weekend. More advisories are possible, especially if severe storms develop.
