A polar vortex is slated to sweep most of the continental US bringing winter storm warnings and a hazardous freeze to millions.

The National Weather Service Jacksonville (NWS JAX) says mixed wintry precipitation is possible for the areas they've highlighted on the map. They say total snow accumulations of up to one inch and ice accumulations of around one to two tenths of an inch are possible.

Northwestern New Jersey counties have reported the highest snow totals of up to 7 inches from Sunday’s winter storm. Morris County had the top three totals reported to the National Weather Service with Kinnelon topping the list at 7 inches.
