In trouble as likely to get rained on? (5,1,5)
I believe the answer is:
under a cloud
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for under a cloud that I've seen before include "Discredited" , "soon to experience four [DOWNFALL]?" , "In disgrace or disfavour" , "Place for cats and dogs together" , "in the doghouse?" .)
