Rare Day 7 Slight Risk out for the Plains/Midwest, including Iowa. That would be Monday.
They're not that rare these days due to machine learning models like CSU-MLP, but I'm actually quite concerned about this one as the SPC mentioned "all-hazards" on Day 7 already which means tornadoes.

I think there could be capping issues though, the ECWMF showed a line of storms coming from Nebraska into Iowa yesterday, while the GFS showed supercells in Iowa, but now both models are showing barely any storms during that timeframe (4-10 pm next Monday) despite the environment being otherwise favorable.
I think the culprit could be the elevated mixed layer here (the green dew point line in the hodograph being relatively low a few kilometers at the surface compared to higher and lower up, this is a layer of dry air that oftentimes prevents surface based storms- the storms that produce those green skies that come before really bad weather).
