1) “D.I. Ray” season-finale,, 10 p.m., PBS. Slowly and solemnly, this season has unfolded two stories. Ray (Parminder Nagra,shown here, best-known for “ER”) has probed a murder involving two crime families, plus an internal story, involving a police conspiracy. Now both end solidly.
2) “Professor T,” season-finale, 8 p.m., PBS. Unlike “D.I. Ray,” this series solves a case each week. It has a good one tonight, but it also tacks on a closing jolt that is sudden, contrived and unwelcome.
3) “Tulsa King,” 8 p.m., CBS. In its second episode, “Tulsa” (which starts a second season in September on Paramount+) sees Dwight (Sylvester Stallone) make in-roads in the legal-marijuana business. He tries to meet his estranged daughter and re-meets Stacy; during their one-night stand, she didn’t him she’s a federal agent.
4) “Snowpiercer” season-opene, 9 p.m., AMC, rerunning at 11:14 and 12:22..This richly crafted series began on a frozen Earth, with scarce survivors on a train that moves constantly. TNT filmed four seasons, then (under new owners) shelved the fourth. Now, 28 months after the third aired, the fourth moves to AMC; the opener focuses on a splinter group’s New Eden village.
5) More new drama hour: At 9 p.m., PBS has “Grantchester” and HBO has“”House of the Dragon,” At 10:08, AMC and BBC America have “Orphan Black: Echoes.” Also, Showtime has “Mayor of Kingstown” at 8:15 and episodes of “Special Ops: Lioness” at 9 and 9:40.
