Sunrise at Duluth harbor had a wintry beauty today.

The webcam at the Lake Superior Maritime Visitor Center captured the scene:

The air temperature was 8 below zero, and you can see an icy steam rising from the water in the canal.

Temperatures are cold today all across Minnesota, but this arctic plunge won't last very long.
