Snowstorm continues today through Sunday; heavy snow and strong winds

We’re in this for a while.

The latest forecast model info shows that our snowstorm will linger in many areas well into Sunday.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential snow pattern today through Sunday afternoon:

Because this is such a long duration snow event, with periods of heavy snow, the Twin Cities metro area could see an additional 8 to 14 inches of snow before it ends late Sunday, with the highest amounts expected on the southeast side of the metro area.

Here are the National Weather Service forecast snow totals:

We might also hear some thunder and see lightning at times this afternoon in southern Minnesota and the Twin Cities metro area.

Parts of southeastern Minnesota will see some periods of freezing rain, in addition to the snow:
