That's not a "now", that's a "still". You wanted to know if I would make the meeting or not. (Hypothetically of course, in this imagined conversation). I didn't have that information. So to begin with, neither of us knew; and still neither of us know. I did have some information though, which was relevant, and which I was able to share with you in a way I wouldn't have been able to without modal operators. If the only information I could convey to you was "yes I will make the meeting", "no I will not make the meeting", or silence, then you would either receive an unfounded claim (as either of those two claims might turn out to be false), or nothing. With modal operators, I can convey the limited information I have.
