The train of gravity waves was not as apparent in more moisture-rich areas like eastern Missouri -- but an arc of clouds was forming along its leading edge. A Pilot Report noted Light-Moderate Turbulence at altitudes of 11-15 kft over the St. Louis MO area.

Mid-level Water Vapor images from @NOAASatellites #GOES19/#GOESEast showed that an outflow boundary from a decaying Mesoscale Convective System over northern Iowa (which produced a few wind gusts >50 knots) also created a vertically-propagating gravity wave that moved S and SW.
