Fresh winter snow moved into the US mid-Atlantic region on Tuesday, shutting schools and offices in the nation's capital and elsewhere as the mid-section of the country remained in the grip of Arctic air that showed no signs of easing. From 2 to 8 inches of snow was forecast to fall from northern Virginia, across Maryland, Pennsylvania, Delaware and into southern New England, Brian Korty, meteorologist with the National Weather Service (NWS) said in a forecast.
