1) “Awkwafina is Nora from Queens” debut, 10:30 p.m., Comedy Central. Nora Lum grew up in Queens, with a Chinese father and grandmother; she was 4 when her mother, who was Korean, died. She was an ambitious kid who studied classical music in high school and journalism in college, then became an outspoken rapper/actress named Awkwafina, now with an Oscar nomination for “The Farewell.” Here, she borrows only the funny parts of her life, for a loosely amusing series about a 30-year-old who is jobless and clueless and still living at home.
2) “Expedition With Steve Backshall,” 10 p.m., PBS. The world noticed Greenland when Donald Trump wanted to buy it. Reporters visited an island with lots of ice and only 56,000 people. Now Backshall skips most of those people, except for the 400 living in its northernmost village. He wants to illustrate global warming by making the earliest-in-spring kayak trip across the world’s largest fjord. His team stops in an abandoned fishing village, throws stones to discourage a polar bear and sees some truly gorgeous icescapes.
3) “Riverdale,” 8 p.m., CW. After a five-week break, the show returns with an episode that has key high school moments: Riverdale High (Archie’s school) plays Stonewall Prep (Jughead’s school, for now). Betty works on a story about their rivalry. And Cheryl battles the new cheerleading coach.
4) “Modern Family,” 9 p.m., ABC. Lots of people show up unexpectedly. There’s Manny’s dad (Benjamin Bratt) … and the former neighbor who became a tech titan (Josh Gad) … and the guy who used to live in the house Mitchell and Cameron have (Paul Dooley, 91).
5) “Good Trouble,” 9 p.m., Freeform. Usually an 8 p.m. show, this is now at 10, nestled behind the “Party of Five” reboot. That’s a logical spot for a smart show about young people starting their post-college lives. Tonight, Davia gets unwanted notoriety as a teacher; Callie helps Judge Wilson after a devastating loss.
