Light hail and snow cover the country (8)
I believe the answer is:
thailand
'the country' is the definition.
(Thailand is an example)
'light hail and snow cover' is the wordplay.
'cover' indicates the answer is hidden within the clue (I've seen 'covered' mean this (the answer is covered up by the clue)).
'THAILAND' is hidden within 'light hail and snow'.
(Other definitions for thailand that I've seen before include "Country in SE Asia, capital of Bangkok" , "SE Asian country" , "Modern Siam" , "Asian nation" , "Phuket's location" .)
