Visible satellite imagery indicates a few overshooting tops associated with the convection from central IL back west into central IA. The over-shooting top product did highlight the region over northern IL (where currently a golf ball size hail report was just received) but the ones to the west were not highlighted. The ones to the west must not have been large enough of an over-shooting top to trip the algorithm. Since the one indicated did product the big hail it tends to add confidence to use of the product.
