LACROSSE, Wis. – Southeast Minnesota, indeed the whole Driftless region, will be stuck in a polar vortex at least through Sunday. The National Weather Service said 10-above is as warm as it will get. Lows will remain well below zero. Overnight in Winona was 15-below. What about wind chill? You don’t want to know. You might take solace knowing that wasn’t as cold as Duluth’s minus-33 in the wind. There were minus-40s wind chills elsewhere toward Canada.
