Arctic outbreak grips the Northern Plains, Midwest and Northeast

Dangerous, life-threatening cold has spread over much of the Northern Plains, Midwest and parts of the Northeast, with another surge of Arctic air expected to drop wind chills close to minus 40 degrees later this week—leaving some places in the Lower 48 colder than Alaska. After a brief reprieve Wednesday for the Northeast, the season's most bone-chilling air will race into the Northern Plains and Midwest by Thursday. Low temperatures will drop into the single digits and teens across much of the Upper Midwest on Wednesday; Detroit is expected to reach a high of only 6 degrees.
