You mean to ski down the ski area slopes, which are a ways south from the true summit? Black closed for the season quite a while ago. Would be surprised if the conditions are decent enough at this point but haven't driven past recently. There is no snow at lower elevations and what exists is ice or otherwise rotten. If you mean to ski down the ski trail to the cabin on the west side, same problem - things have gotten icy and rotten on most unmaintained trails from what I have seen from hiking on the sub-2,500 ft. peaks. You might ask the folks at the Jackson ski touring center or the J-Town Deli and see if they have intel. Maybe the snow on the actual slopes has held up.
