Eastern half of U.S. in icebox, weather service says.

 

 

          There will be 3 to 9 inches of new snow to go along with that from the Virginias to Massachusetts, the National Weather Service said. Much of it is expected to fall in the daylight hours Tuesday. Add the areas that are frigid already, and the eastern half of the nation will shiver through temperatures 10 to 25 degrees below average. The vast area is expected to stay in the icebox until the weekend. That can mean lows in the teens in Memphis, Tennessee, and in the single digits from Louisville, Kentucky, to Boston.

           A second frigid weather system is moving down from Canada and will plunge low temperatures into the double-digit minus degrees all along the border. Whipping winds will knock the wind chill down to 20 to 40 below zero from the Upper Plains states to northern Missouri. A small but intense snowstorm is dumping up to 10 inches of snow in metropolitan Chicago as moisture over Lake Michigan mixes with frigid air.
