Excellent case of open cells of the Washington coast seen with WorldView, Turning to cumulonimbus onshore. April 1st 2015. It was the loudest thunder I ever heard in Seattle.
The image below shows a zoomed in portion, this time using the 3-6-7 MODIS channel blend (0.4,1.6,2.1 micron). Look carefully at the centers of the open cells. Quite a few have little patches of what I take to be evaporating precipitation/cloud. They actually show up slightly blue in the 3-6-7 blend.
