Narrative:
Descending through 13000 ft for 11000 ft at 250 KT, ATC advised VFR traffic 10-11 O'clock position, 4 mi, 9700 ft. Coming out of an overcast, we began looking. TCASII advised 'monitor vertical speed' followed quickly by 'descend now.' the first officer disengaged autoplt, pushed the nose over aggressively. After visually acquiring conflict and TCASII 'clear of conflict,' we leveled at 10000 ft, advised ATC of event, and climbed back to 11000 ft. We continued for uneventful landing in mco. Call to center indicated the conflict was a citation flying VFR with orlando departure from leesburg. He stated he had us in sight. Regardless, we didn't know that and our TCASII didn't like it. Center said it isn't unusual for cpr aircraft to depart the mco area VFR even though they climb through the arrs into mco. WX was a factor that day as we had extensive vectoring due WX and reduced visibility. It may have been technically VMC but not by much. Supplemental information from acn 557775: apparently, the citation was being worked by approach.
