"We will have some folks out looking at those bridges that are up high and some of those elevated ramps and things and just keeping a real close eye because that's where it will freeze if it is going to," said Mark McKinnon of the Georgia DOT.
The FOX 5 Storm Team says there may be some snow in the higher elevations overnight Thursday but black ice is the bigger concern in metro area.
DOT officials say Friday morning commuters should leave extra early and pack lots of patience for the drive into work.
"Drive very slowly and carefully and just be aware that there could be ice there. Another thing we would like for you to do is if you do encounter some ice, give us a call and let us know. Our folks can't be everywhere all the time," McKinnon said.
A road in Marietta was closed after a tree fell on a vehicle early Wednesday morning.
According to Marietta police, Whitlock Avenue at Brookwood Drive was shut down in both directions for a few hours while crews worked to clear up the debris and repair downed power lines.
Police say the person inside the vehicle was not injured.
