ATLANTA (NBC) - Flanked by state troopers, Nathan Deal looked and sounded like a heavily-protected forecaster in chief, delivering a weather bulletin for the biggest day in his public life.

"Weather reports show that a significant amount of snow and ice could hit our state Sunday night," Deal said during a Capitol news conference. "Please, everybody take safety as your first priority."

Outside the Capitol, where workers rigged the west front for Deal's Monday inauguration, the change in the air was more meteorological than political. Nathan Deal's outdoor ceremony is a question mark, to be settled at midday Sunday. Plan B moves it to the House chambers Monday.
