A strong low pressure system tracking through the southern Great Lakes caused gusty northeast winds across east-central and northeast Wisconsin, which caused some isolated damage and widespread lakeshore flooding in Brown and Oconto counties.  The lakeshore flooding damaged several homes near the bay of Green Bay, with over $500,000 of damage in northern Brown and southern Oconto counties. The northeast winds funneled down the bay of Green Bay, which backed up the Fox and East Rivers, causing flooding further inland in Green Bay.
