DES MOINES, Iowa — Frigid temperatures iced the Upper Midwest today as a massive storm that dumped more than a foot of snow in several states from Iowa to New England neared the end of its cross-country trek.

Commuters from Des Moines to Chicago were warned of morning temperatures reaching 10 degrees at best and icy roads. Wind chill values could dip to as low as minus 25 in parts of Wisconsin, Iowa and Illinois, according to the National Weather Service.

"It's already very cold across the entire region," said Casey Sullivan, a weather service meteorologist in Romeoville, Ill., adding that parts of northern Illinois may hit only 2 degrees.

Des Moines, which saw 16 inches of snow by Wednesday, could see a high near 9 degrees but wind chill values could make temperatures feel like negative 25. In Madison, Wis., near where almost 19 inches of snow fell, the wind chill could hit minus 20, according to the weather service.
