Greet the weather (4)
I believe the answer is:
hail
I believe this clue is a double definition.
'greet' is the first definition.
(I know that hail is a kind of greet)
'weather' is the second definition.
(hail is a kind of weather)
'the' acts as a link.
(Other definitions for hail that I've seen before include "Greet, acclaim" , "Call, a taxi say" , "Greet loudly" , "wintry weather" , "Greet(ing) - frozen shower" .)
