I also got four supercells, all around Jacksonville, IL and southwest of there. Actually, the fourth one almost got me. All four were tornado-warned, and three of them produced, though not while I was on them. They all had impressive wall clouds, though, and some likely funnels. The third one produced a huge, striated wall cloud of the kind you just don't see in Illinois - about as close as we get to a mothership in these parts:
This wall cloud was at least a couple miles across, if not more - one of the largest I have ever seen.
After this storm cycled and produced another wall cloud a little before 7, and soon thereafter, things got a bit more exciting. After a bit of road confusion, I was about to give up the chase a couple miles north of Woodson for lack of an east option, when I noticed a lowering with violent motion and some rotation just to my west or WSW. Just then, the warning on the WX radio sounded to announce a TOR based on rotation 2 miles west of Woodson. Seeing a nasty blue-green core coming at me from the west and northwest, I knew I needed to get out of there, so I blasted south on route 67, trying to either beat the meso or thread my way between it and the approaching core behind it. Soon either the lowering I first saw or another one was looming right ahead of me, now a solid, bulbous lowering. I pulled off to let it pass ahead of me, then blasted south behind it. The lowering looked to be just a few hundred feet above the ground over the field just to my east between me and the town of Woodson. I really thought a tornado was about to touch down in the field or in the town. As soon as I passed it I was blasted by a dusty RFD that I would estimate around 60 mph or so. No tornado occurred there, but the same storm did produce a series of tornadoes beginning about 12 or 13 miles east of my location, including the one Skip got. It also produced 3.25" hail south of New Berlin - glad I managed to avoid the hail core!
All in all, an excellent chase, even though I missed the tornadoes. Still, some of the best storm structure I have seen in Illinois.
Full chase report coming on my Web site in a couple days - I will post an update when it is ready.
