Cold and wet in general, accommodated like sow? (6)
I believe the answer is:
Here is my best explanation:
'cold and wet' is the definition.
(I've seen this before)
'general accommodated like sow?' is the wordplay.
I cannot quite see how this works, but
'general' could be 'lee' (Robert E. Lee - US revolutionary commander) and 'lee' is located in the answer.
'like' could be 'y' ('y' can be similar in meaning to 'like') and 'y' is located in the answer.
The remaining letters 'st' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'in' is the link.
(Other definitions for sleety that I've seen before include "Such wintry weather" and "Cold and wet".)
