Folks in central and northern Minnesota woke up to temperature readings of 15-below zero in some places this (WED) morning, and snow is expected for much of the state today. And the coldest air of the season is still to come, even for the lower half of the state. The National Weather Service predicts that much of the state will see overnight lows tonight ranging from minus-10 to minus-25, and that temps on Thursday will likely not get above 5-degrees. Wind chills could reach 40-below in much of the state as well. It is expected to warm up a bit over the weekend.
