"An isolated cumulonimbus storm developed over the Pacific Ocean a few miles south of the coast of Panama City. It sat atop a temperature inversion that created a thick overcast layer of clouds. The strong updrafts of the storm quickly reached the tropopause and spread out, creating the characteristic anvil. The strongest updrafts pierced the tropopause and turned into what scientists call the overshooting tops. The entire frame was lit by a single lightning from within the storm in a moonless night on June 16, 2016."
