A cold snap is coming this week, with temperatures running 15 to 25 degrees below normal. The National Weather Service Climate Prediction Center looks ahead not just the coming six to ten days, but into the week after that, and predicts much of the Upper Midwest to be colder than normal into the middle of November.
There is a chance of snow Monday, but snow is possible on and off through several days this coming week.
