    For a part 91 operator, the reported conditions can be 0-0.  There are no requirements for the weather minimums to commence or execute the approach.  It is different for the airlines or part 135 operators.  FAR 91.175 details the requirements for descending below the MDA or DA under part 91.

    For a 121 or 135 operator the ceiling does not matter but the prevailing visibility does.  To answer your question in reference to an air carrier, the ceiling can be below minimums but the visibility must be above minimums.
    If a crew has passed the final approach fix inbound and receive a new weather report indicating the visibility has deteriorated below minimums, the crew can continue the approach to minimums.  I hope this helps.
