Wintry weather on TV? (4)
I believe the answer is:
snow
'wintry weather' is the definition.
(weather occurring in winter)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for snow that I've seen before include "Weather condition" , "TV newsman" , "Basic White Christmas ingredient" , "Frozen rain" , "'See amid the winter's ... (Christmas carol)" .)
