The mild winter for the middle and eastern parts of the country are over and the cold has returned with a full blow, NBC News reported.
Forecasters said that an arctic air blast that appeared over the weekend is expected to keep temperatures low overnight on Monday into Tuesday. And for parts of the country that means temperatures below zero.
Minneapolis' low temperature Tuesday morning is expected to drop to 10 degrees below zero, and wind chills all the way down to minus-40 are forecast for parts of the Dakotas and other parts of Minnesota, the National Weather Service said early Monday evening.
Subfreezing temperatures will stretch all the way to the East Coast, where forecast low temperatures for Tuesday include 13 degrees in Boston, 18 in New York City and 12 in Washington, D.C.
