203549 -- transition ??
203725 -- few ripples in cloud top -- no obvious entrainment features

210300 -- undulations in cloud top
210405 -- break in echo 
210500 -- turn at end of leg
210655 -- sm. notches at cloud top -- entrainment ?

211012 -- entr feature ?
211111 -- same ? in weak region of cloud
211224 -- xition to weaker cloud
211317 -- turn at end of leg -- which oval ?]
211500 -- end of turn starting leg  -- nope -- confused
211745 -- cloud v. weak no drizzle (max Z at cloud top)
211846 -- possible (small) entr. feat.
