The remnants of Hurricane Isaac inched across Missouri, Illinois, and Indiana during Labor Day weekend of 2012. The remnants moved slower than originally anticipated, causing much of the heavy rain to fall across portions of Missouri and Illinois rather than Indiana. 48 hour rainfall totals through 7:00 AM Monday September 3 showed that much of central Indiana received 1 to 3 inches of rain. Below are some maps of rainfall amounts across the area, click any image to enlarge:
