SPC outlooks for Sunday and Monday are here

And they're pretty much is in line with what my gut was telling me:

The SPC is predicting that the storms will form over SE Minnesota/SW Wisconsin/NE Iowa/NW Illinois, and head southeast from there.  By day 4 (Monday), they've highlighted the southern Ohio valley as the next target of severe weather.  No mention of Michigan in this one.  

I still think there's a chance for severe storms on Sunday - namely an MCS that forms during the day - however those chances appear to be dwindling with every run.  More than likely we're going to be looking at rain Sunday, and a chance of thunderstorms Monday.
