Watch it

“Glee” (9 p.m., Fox). Enjoy it, it’s the last new “Glee” until April. The regionals are looming, Quinn’s secret is unraveling, Sue’s scheming is in overdrive and Will has got to do find a way to keep Emma from marrying Ken. Hope you like cliffhangers.

“Top Chef” (10 p.m., Bravo). The season finale, and the three remaining cheftestants will be at Healdsburg’s Cyrus. My money’s still on Kevin. With the caliber of these chefs, I expect nothing less than the greatest finale in the history of the show.

Record it

“Modern Family” (9 p.m., ABC). Phil and Claire grinchilly threaten to withhold Christmas from their kids until they fess up to something. Come on, I think that punishment would crush Phil more than the kids.

“Dinner: Impossible” (10 p.m., Food Network). Nice local twist tonight as our own Guy Fieri presents host Robert Irvine with a challenge to create a huge feast for the Santa Rosa Boys and Girls Club.

“Spectacle: Elvis Costello with . . .” (10 p.m., Sundance). The rock veteran is back with a second season of his chat show. You might have heard of tonight’s guests: U2’s Bono and The Edge. Expect some pretty cool music talk and an even cooler jam session.

Skip it

“Real World/Road Rules Challenge” (10 p.m., MTV). It’s the season finale. But really, if you’ve watched this far, you’re already lost to the dark side.

“Steven Seagal: Lawman” (10 p.m, A&E). I’m already over it.
