1) “9-1-1: Lone Star” season-opener, 8 p.m., Fox. Last season ended with a dust storm hitting Texas; this one starts with a blizzard. That happens just as Owen (Rob Lowe, shown here) tries to separate himself from the world. The world promptly shows up at his door, with the potential for danger, romance and heroics. This starts a multi-week story that mixes big action scenes and deeper personal moments.
2) “The Cleaning Lady” debut, 9:01 p.m., Fox. Thony was a doctor in her native Cambodia and then in the Philippines. But in the U.S., trying to get her son a transplant, she’s a cleaning lady, working with her Filipino sister-in-law; then she bumps across the Mob and finds possibilities for bad or good. The story (from an Argentine series) takes a while to set up, but then delivers strong potential.
3) “The Bachelor” opener, 8-10 p.m., ABC. Clayton Echard, who was eighth on “The Bachelorette,” takes over. He’s 28, a former tight end (6-foot-5, two catches, 14 yards) for the University of Missouri. Now he sells medical devices … and has lots of medical women to choose from. That includes a doctor and five nurses, one of them (Lindsay Dobbs) a former Miss Teen America. Others range from a flight instructor to a spray-tanner and Marlena Wesh, the U.S. college record-holder in the 400-meter run.
4) “Kenan,” 8 p.m., NBC. This is the season-opener, if we forget about the Christmas episode – which we really should. That awful episode required Kenan Thompson to behave like a jerk, something that just doesn’t fit; now, fortunately, he’s back to good-guy turf. His brother, a busy player on the dating apps, convinces him to try. It’s a funny episode, followed by another new “Kenan” at 8:30. At 9 is “That’s My Jam,” the Jimmy Fallon game show, with Alessia Cara and Josh Groban as guests.
5) “Abbott Elementary” and “Black-ish,” 10 and 10:31 p.m., ABC. On Tuesday, one show officially starts its first season and the other starts its last; first, these reruns show what led to this: The “Abbott” pilot has writer-producer Quinta Brunson starring in a clever story of hard-working teachers in a barely working school. Last season’s “Black-ish” finale sees Dre ready to make a drastic career change
