WeatherAs forecasters anxiously watch models for better agreement, one thing is clear: a major winter storm-named Winter Storm Fern by The Weather Channel-is forecast to impact a vast portion of the United States this weekend, bringing a dangerous combination of heavy snow, ice, and extreme cold to much of the country. Winter Storm Fern is expected to impact more than 230 million people across roughly two-thirds of the U.S., stretching across approximately 33 states.
