Crossword Genius

More short argument the following day (6)

Ross

I believe the answer is:

morrow

'day' is the definition.
(morrow is a kind of day)

'more short argument the following' is the wordplay.
'short' means to remove the last letter.
'argument' becomes 'row' (I've seen this before).
'the following' means one lot of letters go next to another.
'more' with its last letter removed is 'mor'.
'mor'+'row'='MORROW'

I've seen this clue in The Times.
