We decided to hang around in the area and see if any of the following cells would do anything, but they were undercut by the outflow from the inital supercell. At this point we decided to race east to make a play on the original cell/line, which had now taken the form of a bow echo and was pushing east across NW. Illinois. We was not able to get far enough north to experience the widespread damaging winds over 70mph, but instead ended up with a nice shelf cloud and 40-50mph winds at my position just east of I-39, near Hampshire, IL.
This was an alright chase, but it could have gone better.
