An icy start to spring semester

University of Wisconsin–Madison students returning to class on Tuesday were greeted by an arctic air mass that brought subzero temperatures and 20-below windchills. Some students made the most of winter by sledding; others refused to acknowledge it by wearing shorts. Luckily, by Friday temperatures reached a more seasonal 24 degrees. And students carried within them the knowledge that the days will lengthen and temperatures will rise this semester — eventually.
