Foggy Sunday; wintry mix to snow Sunday evening into Monday, with heavy snow staying north

One year ago today was the Saturday before the Super Bowl.

There was some nice fluffy snow that day as multiple festivities took place in downtown Minneapolis:

At times during the 1 to 2 inch snowfall it looked like a beautiful snow globe.

Super Bowl Sunday was sunny and very cold, so visitors had a nice sample of wintry Minnesota weather during their stay.

Fog lingers

Dense fog lingers over much of Minnesota today, and there are dense fog advisories:
