Weekend forecast: Snow returns Saturday evening, lingers through Sunday

Heaviest snow expected in far southern Minnesota

Through Thursday, our official Twin Cities October 2020 snowfall total was 8.1 inches. Twin Cities weather records show that our highest snowfall total for the entire month of October is 8.2 inches, set in 1991.

The light snow that we’ve seen this morning could be enough to put us ahead of October 1991. The official MSP airport snowfall total will be updated around 1 p.m. today.


Afternoon update

We’ve now set a new Twin Cities snowfall record for the month of October:

As you can see, St. Cloud and Eau Claire have also reached new October snowfall records.

Weekend snow outlook

The next batch of snow may spread into parts of southwestern and west-central Minnesota late Saturday afternoon. As we go through Saturday evening and Saturday night, the snow area expands to cover most of the southern half 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 evening through Sunday evening:
