Temperatures across the Great Lakes, Ohio Valley and the Mid-Atlantic will drop 10 to 20 degrees Fahrenheit below average, the service said. The freeze will follow the weekend's run-ins with power outages, canceled trains and planes, overnight stays at the airport and traffic jams. Local officials warned residents to limit their time outside to prevent frostbite and to avoid treacherous travel conditions. One saving grace of the storm: heavily populated coastal communities from New York to Boston largely escaped major snowfall after days of sometimes dire predictions. President Donald Trump urged Americans affected by the winter storm to "be careful" in a tweet early Sunday.
