I have a very similar story from around 1986 or so. We had a big lightning strike and a ball formed, also about tennis ball sized. It traveled slowly through our dining room over the heads of all the adults sitting there, then moving into the living room. It also aimed for the crt tv, although in our case I don't think it did much of a jump as it entered it. It switched the tv off and caused a power surge that made all the lights flicker, but everything was fine after (although the tv had a discolored spot that even with degaussing took some time to go away). The really interesting thing for me at the time with it being some kind of lightning was how slow it moved.
