Deep freeze slams Midwest before taking aim on Northeast: Latest forecast

Dangerously cold temperatures have taken over the Midwest Wednesday before heading to the Northeast on Thursday.

Wednesday is the coldest morning so far this winter in places like Chicago, where parts of Lake Michigan are filled with ice.

The wind chill -- what temperature it feels like -- plunged Wednesday morning to minus 18 in Chicago, minus 32 degrees in Minneapolis, minus 29 in Green Bay and minus 13 in Indianapolis.

The deep freeze then turns to the Northeast.

Thursday morning the wind chill is forecast to fall to minus 4 degrees in Boston, 6 degrees in New York and minus 10 degrees in Watertown, New York.

Even the South will feel the freeze. The wind chill is forecast to drop to 14 degrees in Raleigh, 23 in Atlanta and 21 in Nashville.
