1-minute imagery + CI + satellite winds giving a heads-up for near-future storms?

J-Money:

Relatively clear areas over central/southern IL so far today, may see increasing convective development the next 1-2 hours.

1-minute visible pictures and regular CI images have highlighted an agitated cumulus field near the MO/IL border, with radar showing scattered storms.  At the same time, satellite derived winds confirm strengthening SSW flow coming into IL, around the cold-core vortex over southeast IA/northeast MO.  This matches well with SPC meso-analysis data.  See attached image.
