The remains of Tropical Storm Bill moved through Texas and Oklahoma and up through the Midwest. As a result, it produced quite a bit of rain in southern Illinois.
While it is difficult to separate out the rainfall exclusively from Tropical Storm Bill, this radar-estimated rainfall image of the past 7 days shows the pattern. Areas in yellow and red received at least 3 inches of rainfall. The widespread areas in red south of Interstate 70 received in the neighborhood of 6 to 8 inches of rain.
Missouri, Indiana, Ohio, and Kentucky received significant rainfall as well.
