ATLANTA—Atlantans awoke to relatively mild weather on Jan. 29, but forecasters warned that streets could still become icy as fans arrive for the Super Bowl, with temperatures expected to drop more than 20 degrees during the day.

More than 100 of Tuesday’s flights were canceled at Atlanta’s airport and schools were closed across the city “in an abundance of caution” ahead of the storm front, which was churning toward Georgia Tuesday just as thousands of fans begin pouring into town for Super Bowl 53.
