A dangerous deep freeze is blasting the Northeast and Midwest, where record-breaking cold temperatures are paralyzing cities and communities.
At least eight people have died in connection with the coldest weather in decades across the Northern Plains and Midwest.
The wind chill in Chicago plunged to minus 52 on Wednesday — the coldest wind chill since 1985. It was minus 55 in Minneapolis, also the coldest wind chill since 1985.
The bone-chilling temperatures are unrelenting in the Midwest, where the Thursday morning wind chills remained in the minus 20s and minus 30s.
Upstate New York has seen several feet of snow in some areas as well as wind chills at minus 38 degrees overnight.
