Take a look at PROC FMM. The Getting Started example shows how to put a mass at zero, which I assume is what the probit part does. It then fits a Poisson to the remaining values. A log-normal distribution could be selected instead. I hope I have not misunderstood your question.

A quick followup. You will have to use the PROBMODEL statement to get the first hurdle to be a probit, rather than the default logit.
