A winter storm packing heavy snow, ice, gale-force winds and tornadoes rolled out of the Midwest and continued its march across the nation Sunday. Almost 250,000 homes and businesses were dark in South Carolina, North Carolina, Georgia and Florida. Over 6,000 flights into, out of and within the country had been canceled or delayed as of 6 p.m. ET, according to the tracking website flightaware.com. The impact of the storm varied greatly from neighborhood to neighborhood. Jackson, Mississippi, saw trace amounts of snow early Sunday while 25 miles to the northeast, the hamlet of Goshen Springs was blasted by more than 8 inches. Nashville could end up getting 3 inches of snow, while other parts of Tennessee a foot of snow. The storm, dubbed a "Saskatchewan screamer" because it originated in the Canadian province of Saskatchewan, is headed into the Northeast, dropping snow, sleet and rain around the densely populated Eastern Seaboard. 📸: @apnews and @gettyimages #snow #snowstorm
