Thunderous and grey in conclusion, cumulonimbus primarily overhead? (6) I originally wanted to see “overhead” as the definition in this clue — in spite of the fact that it seemed an unsatisfactory definition. Thanks to a prompt by a commenter (thank you, ernie) I am now much more inclined to see the clue as an &lit. It may be a slightly laboured &lit. but any &lit. is a triumph.
