It’s dry, but wet weather is coming in (6)
I believe the answer is:
raisin
'it's dry' is the definition.
I can't judge whether this definition defines the answer.
'wet weather is coming in' is the wordplay.
'wet weather' becomes 'rain' (rain is wet weather).
'coming in' is an insertion indicator.
'rain' going around 'is' is 'RAISIN'.
'but' is the link.
Can you help me to learn more?
(Other definitions for raisin that I've seen before include "Dried red grape" , "A dried grape used in cake" , "Dried fruit" , "A dried grape, nice in cake" , "Large dried grape" .)
