IRON MOUNTAIN — Temperature-wise, the worst is yet to come.

For much of the Upper Peninsula, high temperatures through Thursday will not be warmer than the single digits above zero, with nighttime lows mostly between 5 below and 25 below zero, the National Weather Service said today.

The good news, though, is that high temperatures in the 30s are predicted for the weekend.

The central U.P. was spared the brunt of a storm today that brought heavy snow and gusting winds, creating blizzard-like conditions across parts of the Midwest. Up to 14 inches of snow was expected in southern Wisconsin, where plow drivers in Sheboygan were having a hard time keeping roads clear, the Associated Press reported.

National Weather Service meteorologist Tyler Hasenstein told the Minneapolis Star Tribune that temperatures Wednesday could fall to minus 30 degrees, and could feel as cold as minus 60 because of the wind chill.

In the Upper Peninsula, the worst conditions are expected late Tuesday through Thursday, when wind chill readings will frequently range from minus 20 to minus 40.

“We are very confident this cold is going to be significant,” Hasenstein said. “People are right to be concerned.”

Whiteout conditions may occur on roads in the Lake Superior snow belts, especially Wednesday and Wednesday night, when strong and gusty winds are expected.

For the Dickinson County area, about 2 to 5 inches of snow was expected with today’s storm and there is a chance of snow into Wednesday. About an inch of snow had fallen by mid-morning.

The forecast calls for a high of 14 on Friday and 30 on Saturday, with a chance of snow Saturday night into Sunday.
