One thing this setup has going for it (among others) is the lead system that passes by midweek serves to kickstart the moisture return process from the GOM. The cold front with that lead system may only settle down into the central parts of IL/IN/OH. We are still limited by time of year, so don't expect outrageous dews too far north, but this particular evolution with the preceding system means they will be higher than they otherwise would've been.
