Lake Effect Snow on January 31-February 1, 2011
Last updated 2/2/11
A day before a large blizzard affected southeast Wisconsin and northern Illinois, heavy lake effect snow fell over Kewaunee, Manitowoc and Door counties on January 31 and February 1, 2011. Over a foot of snow fell in several locations in the lakeshore counties as persistent northeast winds picked up moisture from Lake Michigan, depositing it as snow. A two day storm total of 16.4" was measured on the southwest side of Kewaunee by an official COOP observer.

Even inland locations, like Green Bay and Chilton, picked up a few inches of snow as the lake moisture combined with an upper level low pressure system that was moving across the state.
As the Midwest blizzard grazed northeast Wisconsin late on February 1 and early on February 2, strong winds developed, creating blowing and drifting snow. A few more inches of snow fell in Manitowoc, Calumet and Winnebago counties associated with the winter storm.
