Later in the flight see quite a bit of embedded convection:
See the plumes of high reflectivity at 45-60km range in this scan with high ZDR at the very tops where glaciating. Can also see remnants of previous convective elements in high Z/ZDR patterns falling toward the radar (30-40k range, 2-4k altitude)
Finally, we also saw evidence for Kelvin-Helmholtz billows in the shear structure - eg this RHI from 1930:
note the braided structures at approx 300-1500m, at 25-60k range - compare these to the paper by Chapman and Browning
