So what happened? 8 April 2019
While you may have found other interesting things, here's what the case designer saw:
There was convection in the southeast as a large storm was wrapping up. Hard to tell from the provided data if it included severe weather.
Skies were mostly clear in Kansas, but the fires there, while relatively low activity, were very numerous and eventually built up a lot of smoke. You could see that beginning in band 1 in particular. In Southwest Missouri that night the skies were relatively cloud free to start but it would have been smokey near the ground - the weak fires couldn't inject the smoke too high so much would have remained in the boundary layer and with nothing to scour it out, it would move into Missouri, Oklahoma, and Arkansas, potentially leading to respiratory issues.
