1) “Snowpiercer” season-finale, 9 and 9:58 p.m., TNT. As the current heat wave grips much of the country, here’s the exact opposite: The temperature outside is minus-122 Celsius, which is worse than it sounds; in Fahrenheit, we’re told, that’s minus-188, People are safe only as the train keeps moving. But inside the train, Daveed Diggs and Jennifer Connelly (shown here) battle for control. And outside, there are potent new forces. It’s a tautly crafted finale, but don’t expect an ending. Mostly, this propels us to next season. Read more…

1) “Saturday Night Live,” 11:29 p.m., NBC. It was beefy-guy night, when this aired on Super Bowl eve. JJ Watt, 6-foot-5, 288, hosted; Luke Combs, 5-8, 198, sang (shown here). Watt is a pro football star – three times named defensive player of the year. Combs played football in high school, but then soared as a singer. He’s quicklty had eight songs reach No. 1 on the country chart; “Beautiful Crazy” stayed for seven weeks. Here, he offers the important musical message: “Beer Never Broke My Heart.” Read more…

1) “American Masters: Unladylike,” 9 p.m., PBS. This summer’s PBS shows have been propeling us toward a milestone – the 100th anniversary (Aug. 26) of women’s vote in federal elections. But before the national change, individual states stepped in. We meet Dr. Martha Hughes Cannon, who was elected in 1896 to Utah’s state senate and sparked health reforms; her statue (shown here) is alongside the state capitol. And Jeannette Rankin, elected by Montana to Congress in 1916. It’s a strong hour that also includes black, Latina and American Indian activists. Read more…

1) “In the Dark” season-finale, 9 p.m., CW. For the second straight season, “Dark” started slowly and built to a crescendo. Murphy (who is blind) and friends have until midnight to find and return the drugs Ben stashed before his death. Now they collide with Dean (the crooked ex-cop), who also wants the drugs. This has a too-long detour that strains believability, but then wraps things up powerfully … and propels us toward next season. Despite its flaws, “Dark” has subtly gifted actors (especially Perry Mattfeld and Brooke Markham, shown here, as Murphy and Jess) in a gripping story. Read more…

1) “Tough as Nails” debut, 8 and 9 p.m., CBS. Here is tough-guy Americana – a retired Marine with four combat tours, a scaffold-builder, two firemen and more. And here are tough women, too – a farmer, a welder, an ironworker … and Michelle Kiddy (shown here), baggage-handler who is 62 and described as “5-foot-nothing.” That’s the charm of this working-skills show. which Phil Keoghan co-produces (with his wife), directs and hosts. The bad news is the repetition of cliches; the good news is a solid human core. Read more…
