Severe weather is expected to bring subzero temperatures the northern Plains as soon as Thursday, then reach the Mississippi Valley, the Northeast and the Ohio Valley by Sunday.

A powerful winter storm is peaking as it moves east, battering the Midwest, Great Lakes and Northeast with blizzard conditions, damaging ice, widespread power outages and major travel disruptions.

From emergency supplies to stick in your car to warmth-giving winners and power outage heroes, be sure to stock up while you still can.
