The second arctic blast in a week is expected to start in the Upper Plains on Tuesday, moving to the Midwest on Wednesday and the Northeast on Thursday. Meanwhile, a winter storm that formed in the Northwest on Sunday was forecast to dump snow along a 2,000-mile-long corridor from Montana to Ohio through Tuesday.

Kevin Roth, lead meteorologist at The Weather Channel, said Chicago would likely not see temperatures above zero on Wednesday. Northeast cities such as New York and Boston, he added, would struggle to achieve highs in the teens on Thursday. "People need to be careful because of the frostbite threat," Roth said. "It's going to be bitter. Kids heading out to the school bus need to make sure they are wrapped up warm and have their skin covered up. It will be the coldest weather most people have experienced this winter."
