Narrative:
I was flying with passengers to ads. While being vectored on the downwind into ads at 3;000 MSL an aircraft closed on us from eleven o'clock. The target started at 600 ft below and climbed rapidly into us. The TCAS called a traffic alert then commanded a climb. I disconnected the autopilot; selected climb thrust and pulled the nose up; asking my pilot not flying to inform ATC that we were vacating our assigned altitude for an RA. He did and the controller said no problem; calling out traffic a mile to the left (it was much closer than that). The RA continued until 4;000 ft before we received a 'clear of conflict'. I returned to my assigned altitude and landed without further event. We never saw the other aircraft as he was hidden by clouds. Based on radio transmissions I think the aircraft was a VFR cessna that climbed to maintain visual conditions but was in the clouds when we passed him. The TCAS worked perfectly and crew coordination on the escape was excellent.
