Past Events

This page serves as a location to find past meteorological event information for Northern Illinois and Northwest Indiana. 

To the right is a link to Storm Data, a monthly publication by the NWS's National Climatic Data Center.  Storm Data will list all of the finalized, quality controlled severe weather reports and damage survey assessments within the NWS Chicago County Warning Area broken down by month. 

Below that, there is also a thumbnail link to an interactive map archive of preliminary Local Storm Reports that are issued by an NWS office whenever a severe weather event is reported.
