After the Thanksgiving storm, the major metropolitan areas of the east has seen a roller coast ride in tempratures with spells of bitter cold and mild interludes. Storms have mainly cut to the lakes or inland bringing rain for the cities and rain or ice for the suburbs.

The next 10 days, that changes. The question is mainly how far inland the snow goes. Its mainly snow or no snow. Even today a low is brewing over the Ohio Valley that is bringing snows to Ohio and soon Pennsylvania, New Jersey and perhaps Long Island before speeding out to sea.
