After checking the 00Z WED GFS...Have decided not to update the graphic...Past several GFS runs have been very similar, as noted by Joel, and the outlook looks pretty much the same.
Overall... If the 00Z GFS were to verify - Pretty decent severe weather outbreak could occur across IA/northern MO Sunday...Agreeing that DSM has the best chance of action. Cold front will move through the area during peak heating, combined with good instability and good directional/speed shear, supercells appear likely, as of right now.
Still a solid 4-5 days before the event, so any minor changes in timing and/or location will have a significant impact on the location of severe weather.
