Hard to say. On a synoptic level, this is a pretty decent setup at least for southern WI. The big question mark though is whether that cap can be broken, especially before dark. Almost has the feel of many a springtime Plains setup in that regard. The annoying thing is, in most springtime setups in this area the problem is not enough cap to prevent early/messy initiation.
Edit: 16Z HRRR says no joy except some mess across western lower Michigan. Local soundings are solidly capped.
