The roads are getting busier and busier as the sky gets darker and darker over metro Atlanta ahead of expected overnight storms, according to Channel 2 Action News.

There aren't too many bad wrecks around metro Atlanta, but I-285 and the Northern Perimeter are congested as the evening commute remains in full swing, according to the WSB 24-hour Traffic Center.

The only notable wreck is in north Fulton County. Johns Creek police tweeted that a wreck on Ga. 141 at Abbotts Bridge Road has left only one southbound lane open, and traffic is building fast.

Storms are expected to make their way into the state overnight, according to Channel 2.

Northwest Georgia is at risk for severe storms after midnight Monday and into the early morning hours Tuesday, according to Channel 2.

“Any of these (storms) over northwest Georgia in that overnight time frame could produce some damaging winds,” Channel 2 meteorologist Karen Minton said. “There’s a risk there might be that isolated tornado. It would be brief, and it’s not going to be a widespread event.”

Much of the day Tuesday is expected to be dry, as Minton said the system shifts to the southeast and the energy fueling the storms heads north. But there is still a chance of rain Tuesday morning when Georgia voters head to the polls, according to Channel 2.

The chance of rain increases to 80 percent for Election Day. By late morning Tuesday, much of the lingering rain is expected to be south of metro Atlanta.

Highs should stick to the mid-70s through Wednesday, according to Channel 2.

Minton said temps should drop and the rain should clear out by the weekend as a wedge of high pressure develops over North Georgia on Thursday and Friday.
