Sunday would be your better bet. It will give the bass another day to get used to the change, and subsequent stabilization of the pressure, and it will allow the waters to start warming back up. I doubt that this cold front is going to hurt their ways of thinking (spawn time coming on), but there will be a few that it will effect more than others.
I am sure that if you worked for it, you could get a good bag today, but I just think that the fishing will be better come Sunday.
