The worst of Winter Storm Astro shifted into northern Wisconsin and Michigan's Upper Peninsula Tuesday, but not before dropping at least a foot of snow in parts of the Upper Midwest Monday.

"Winter Storm Astro dumped a foot or more of snow in a swath from central Minnesota to northern Wisconsin and the U.P. of Michigan," said senior weather.com digital meteorologist Jon Erdman. "For some, that foot-plus snowfall was the first of the season."
