Flakes today; cold and bright on Sunday

It's appropriate that Super Bowl visitors are seeing some snow.

This is Minnesota, after all!

Fans from New England and Philadelphia have seen snow before, but this might be the first time that folks from some warm-weather cities have ever witnessed the beauty of falling snowflakes.

Snow details

A low pressure system is spreading snow across Minnesota this Saturday morning, and the snow will continue through most of the afternoon in many areas.

A smaller area of snow is expected to move through parts of Minnesota Saturday night.

The National Oceanic and Atmospheric Administration's North American Mesoscale forecast model shows the potential snow pattern this Saturday and Saturday night:

NOAA NAM simulated radar Saturday through Sunday morning, via tropicaltidbits

The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of snow.

The highest snow totals are expected north of I-94, where some spots could see 3 to 4 inches:

The winter weather advisory for the heaviest snow areas was expanded around mid-morning to include Isanti and Chisago counties.

Parts of the north metro, especially Anoka county and far northern Washington county, could see 3 to 4 inches of snow by Saturday evening.

The latest forecast model info shows that Minneapolis and St. Paul are candidates for about 2 to 3 inches of snow, with 1 to 2 inches in the far southern part of the metro.

Here are details of the winter weather advisory for Isanti and Chisago counties:
