At home kind but stormy (9)
I believe the answer is:
inclement
'stormy' is the definition.
(associated in meaning)
'at home kind' is the wordplay.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'kind' becomes 'clement' (I've seen this before).
'in'+'clement'='INCLEMENT'
'but' is the link.
(Other definitions for inclement that I've seen before include "Such harsh weather" , "rather wet" , "with heavens opening?" , "lacking mercy" , "Stormy" .)
