Atlanta, Ga. – Thunderstorms could disrupt travel across metro Atlanta Sunday evening, with brief heavy rain possible along I-75 and I-20. Drivers should prepare for slick pavement and slower commutes as showers develop late in the day.

According to the National Weather Service, a 10 percent chance of isolated storms lingers Friday, but storm activity is expected to increase Sunday. Temperatures remain warm, with highs near 89 today and close to 90 by Tuesday. While severe weather isn’t likely, even brief downpours could impact weekend outdoor plans and local roadways.

Saturday brings mostly sunny skies, light east winds, and highs in the mid-80s. Sunday shifts wetter, with a stronger chance of afternoon showers and isolated thunderstorms. Conditions should improve by Monday, with partly to mostly sunny skies returning across the metro.

Residents should plan ahead for changing conditions on Sunday. Secure outdoor items, charge devices, and use caution if traveling during storms. Commuters on major interstates could see temporary slowdowns, especially near downtown Atlanta and eastbound corridors into DeKalb County.

Looking beyond Sunday, the week starts mild and mostly clear. A stronger system could arrive midweek, bringing a 30 to 50 percent chance of rain by Wednesday and Thursday. This system may mark the first sign of a seasonal shift toward cooler, wetter fall weather.

The National Weather Service will issue updates if storm coverage increases. Expect a clearer picture by Saturday evening as forecasters refine timing for Sunday’s rainfall.
