How do you explain this?
It is bone chilling -8F (-22C) right now here in Itasca. But it will slowly warm up as the sun comes up. That part I get. But look what happens after the sun sets. The temperatures keep rising thru the night. Of course, there is no sun around. Lake Michigan water cannot be that warm – after the last few cold days – to explain that.
