Just wanted to start a thread for the central plains for today (it's late, and I don't have much time to go into too many details). The latest 0Z NAM is painting a pretty good supercell threat across IA. A strong shortwave, combined with good moisture pooling at the SFC (and CAPEs AOA 4000J/KG), in addition to deep-layer shear in excess of >45kts would lead me to believe a pretty decent risk of severe thunderstorms is probable. In addition, given the moisture pooling, LCLs will be quite low, so it would be easy for a storm to produce a tornado... However, not overly sure of the tornado threat, since we're somewhat lacking good low-level flow. Although, I'd still see a pretty good bet for supercells with VERY large hail possible, and maybe a couple tornadoes too.
