Overview

Some folks in the Twin Ports of the Duluth/Superior area woke up to piles of snow while others had a dusting. The piles of snow was caused by a narrow band of lake effect snow that developed quickly overnight over western sections of Duluth. This band of snow was about 5 miles wide, with snow rates of about 2 to 3 inches per hour. As the night wore on, the snow band drifted southeast over Superior. The snow band diminished as it moved across far northern Wisconsin after daybreak.

 

At left is a radar loop of the lake effect snow band. The loop is one frame about every 20 minutes from about 1 am until 6:30 am.
