Welcomes quality bit of cold weather (9)
I believe the answer is:
hailstone
'cold weather' is the definition.
(I've seen this before)
'welcomes quality' is the wordplay.
'welcomes' becomes 'hails' (I've seen this in another clue).
'quality' becomes 'tone' (synonyms).
'hails'+'tone'='HAILSTONE'
'bit of' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for hailstone that I've seen before include "a drop of the hard stuff?" , "Small pellet of ice" , "bit icy" , "one in the shower" , "Hard precipitation" .)
