Another batch of snow Saturday evening into Sunday

Highest totals far southern Minnesota

We’ve already set an October record with 8.9 inches of snow in the Twin Cities, and additional snow is on the way.

Scattered light snow showers/flurries are possible anytime this Saturday in northeastern Minnesota. A batch of light snow could spread into parts of southwestern and west-central Minnesota later this Saturday morning and this afternoon. As we go through Saturday evening and Saturday night, the snow area expands to cover most of the southern third of Minnesota, plus much of Wisconsin. Periods of snow will linger in many areas through much of Sunday.

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential precipitation pattern Saturday afternoon through Sunday evening:
