EF5
If the 4KM NAM/GFS is to be believed, then Thursday could foster a favorable setup for a few tornadoes in E IA/IL. We will have to wait and see though. Overnight convection can severely alter the overall setup for any given day this time of year. So looking even 2 days out, is fairly tricky, when trying to asses severe weather potential in these areas.
