This past decade, many extreme, unusual, and memorable weather events took place here in Northern Illinois and Northwest Indiana. To reflect on the significance of these events, we hosted a series of polls on our Twitter and Facebook accounts for you, the public, to decide on the top 10 weather events that we experienced from 2010 through 2019.

We would like to thank everyone who participated in these polls to help determine the top 10 weather events, which are listed below. More information about each event can be found by clicking the links in the table.
