'wintry conditions with sun at the moment' is the definition.
I can't judge whether this defines the answer.

'with sun at the moment' is the wordplay.
'with' means one lot of letters go next to another.
'sun' becomes 'S' (abbreviation).
'at the moment' becomes 'now' (at the present moment).
's'+'now' is 'SNOW'.
