CHICAGO (AP) — The bitter cold that gripped the Midwest forced commuters to bundle up like polar explorers. But by early next week, many of those same people might be able to get by with a light jacket or even short sleeves. Forecasts say temperatures could climb by as much as 80 degrees over the next few days. Experts say the rapid thaw is unprecedented, and it could create problems of its own _ bursting pipes, flooding rivers and crumbling roads.

LANSING, Mich. (AP) — Michigan Attorney General Dana Nessel is seeking to intervene in a lawsuit to defend the federal health care law after a judge declared it unconstitutional.

DETROIT (AP) — Much of the Midwest is preparing for a rapid thaw after this week’s polar vortex sent wind chill temperatures plummeting, but the transition to warmer conditions threatens a new set of problems.

SAULT STE. MARIE, Mich. (AP) — An ice sculpture of an American Indian in headdress has been removed from the front of a hotel in the Upper Peninsula. The sculpture was created as part of Sault Ste. Marie’s Ice Festival. Aaron Payment, chairman of the Sault Tribe of Chippewa Indians, said it could be considered offensive. Mary Lou Kreig, co-owner of Ramada Plaza Ojibway Hotel, says she believed the sculpture would honor American Indian culture. She says it’s “very sad” that the Ice Festival Committee voted to remove it.
