An Arctic blast gripped the northern Plains, Midwest and Great Lakes Saturday morning, with millions of Americans under freeze warnings.
The National Weather Service warned that the Arctic airmass is delivering the coldest temperatures since last winter.
Wind chills in the northern Plains and upper Midwest are expected to plunge below zero Saturday morning.
