Straight line wind and hail with a few embedded tornadoes will be the overnight threat. While conditions will be favorable for tornadoes this afternoon and early evening, there will not be any trigger mechanism unlike first thought. All the action will be midnight or later with the main line moving through just ahead of sunrise.
You can see the RUC has the line back in Illinois at 9 PM and the WRF has it just passed at 8 AM.
The SPC has kept a moderate risk for Wisconsin for today. Possible upgrade later but there does seem to be a lot of bust potential with this system.
Usually big days have to so many things just right that anything slightly not in place can make a forecast bust.
