Old Man Winter has been pretty easy on most of the country so far, but the days of agreeable weather are over in the Midwest, Northern Plains and Northeast — at least for the next few days, NBC News reported.
Fourteen states, from Minnesota stretching all the way into North Carolina, were under wind chill advisories, according to the National Weather Service. More than 50 million people across the country could be forced to deal with the wicked cold during the early part of the week.
Temperatures will hover below zero across across many parts of the Dakotas and Minnesota on Monday, according to NWS.
Meanwhile, some 70 percent of the country was below freezing at 6 a.m. Monday, according to Weather Channel meteorologist Kathryn Prociv.
