snow

I'm a little stuck... Click here to teach me more about this clue!

'cold shower' is the definition.
'snow' can be an answer for 'shower' (thesaurus). I'm unsure of the 'cold' bit.

'son immediately' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'immediately' becomes 'now' (I've seen this before).
's'+'now'='SNOW'

'in' is the link.

Can you help me to learn more?

(Other definitions for snow that I've seen before include "Basic White Christmas ingredient" , "Wintery precipitation" , "Wintry flakes?" , "Weather condition" , "Vessel" .)
