CC thinks the cap may be weak enough that there is decent chance of some storms here in central/southern Iowa. Models are starting to show more convection though mainly bimodally- once in the moderate risk from highway 20 to Minneapolis firing at 1-4pm, one a bit further south from Omaha to St. Joseph south of Des Moines firing at 5-7pm.TL;DR
My gut is saying the moderate risk may be maintained if not just extended south to Ames/Marshalltown which was already almost at 15% tornado risk today. The enhanced 10% risk may get extended down into Missouri given models are showing a good likelihood of storms kicking off down there.
