Atlanta, Georgia – Scorching temperatures and spotty afternoon storms are set to challenge Atlanta drivers and outdoor plans on Friday, July 18th, as a classic summer weather pattern takes hold across North Georgia. Anyone headed out on I-285 or through downtown Atlanta after 2 p.m. should watch for sudden downpours and slick pavement as the mercury climbs to near 94°F.
According to the National Weather Service, a 30 percent chance of thunderstorms will develop across Fulton, DeKalb, and Cobb counties by late Friday afternoon, with heat index values reaching 98°F. Sunny skies will give way to quickly changing weather, and gusty winds up to 15 mph may complicate travel on major routes like I-75 and I-20.
Those in Gwinnett and Clayton counties should limit non-essential trips during peak heat and monitor for changing weather alerts. Outdoor workers, athletes, and event organizers are urged to stay hydrated, reschedule strenuous activities, and have an indoor backup plan. If you hear thunder, seek shelter immediately.
The storm threat lingers into the early evening, but most showers will fade before midnight. Looking ahead, Saturday and Sunday bring more of the same: highs in the low- to mid-90s, afternoon storms possible, and a continued risk of heat-related issues. Local utility crews and emergency managers are on alert for potential power disruptions or downed limbs if storms intensify.
What’s Next:
The pattern remains unsettled through Wednesday, July 23rd, with daily afternoon storm chances and little relief from the summer heat. Stay weather-aware and watch for updated advisories.
