Rendezvous isn't scheduled until the 22nd, so there will likely still be quite a distance between the ISS and Dragon tomorrow. They will be in trail, while the Earth rotates, so depending on where the ISS passes relative to you there's a possibility the Earth might have rotated enough by the time Dragon comes around to not see it. It's definitely worth keeping a look out though.
