CBS has set the bulk of its summer schedule. Under The Dome has added CSI alumna Marg Helgenberger, who will do an extensive arc starting with the Season 3 premiere on June 25. The Stephen King adaptation will move from Monday to Thursday.

CBS Logo 2Extant is staying put on Wednesdays, with Season 2 launching on July 1. CBS’ newest summer original drama series, Zoo, will air on Tuesdays, starting June 30, with NCIS repeats as a lead-in. CBS summer staple Big Brother will kick off its 17th season with a two-night premiere on June 24-25 and will once again air on Wednesday, Thursday and Sunday. Late midseason addition CSI: Cyber will continue airing originals into the summer before making room for Extant. No official word yet on CBS’ Monday summer schedule, but it is expected to resemble the current lineup of 2 Broke Girls, Mike & Molly, Scorpion and NCIS: LA.

Worth pointing out is the presence of midseason comedy Odd Couple on the summer schedule, which bodes well for the comedy’s renewal chances. Here is the rest of CBS’ summer lineup (the network also is expected to air Mom and Elementary repeats in the off season).
