13:33:10 Looking left at top of Sc deck with few holes; aircraft is still over land.
13:39:50 Descending through cloud top, -21C, 870mb, light turb.
13:54a and 13:54b Looking left at shoreline (south view) near upwind edge of "clouds." Note whitecaps on lake and steam fog trails.
14:25 Looking left (south) at steam fog and western shore of lake. A/C data show airmass boundary and wind shift line at about mid-lake.
14:55 Looking right, downwind (east) from west end of track, during turn. The photo seems out of focus, but it's okay -- surface waves are sharp.
15:27 Looking right (south) at western lake shore. Horizontal stabilizer in view. K/A cloud tops -21C; same as Electra down low.
15:55a and 15:55b Looking right (north) near western lake shore at steam fog, onset of cloud formation.
15:56a and 15:56b Looking right (north) near western lake shore at steam fog, during start of turn for next downwind run. Second photo is looking directly downwind.
17:23 Looking right at hole in Sc "pillows" near downwind limit of track. Can see lake surface and virga.
