2) It couldn't be cold tonight.
3) That man couldn't be her father.
(Meaning: It is impossible that that man is her father.)

Gratefully,

Thank you very much, Mr. Micawber, for all your replies.

Is there any difference between:

1) That couldn't be true.
and:
1a) That can't be true.

Is '1' in any way less emphatic? Or more emphatic?

Gratefully,
Navi.
