Midwest awaits thaw days after bitter cold

CHICAGO: The bitter cold that gripped the Midwest forced commuters to bundle up like polar explorers. By early next week, many of those same people might get by with a light jacket.

Just days after the arctic conditions, forecasts say, the region will seemingly swing into another season, with temperatures climbing by as much as 80 degrees. Experts say the rapid thaw is unprecedented, and it could create problems of its own — bursting pipes, flooding rivers and crumbling roads.
