Eureka Eureka

9/8c Syfy
The fourth-season premiere finds the quirky town poised to celebrate its 60th anniversary. Sheriff Carter, still reeling from the departures of Zoe and Tess in the last episode, goes for a jog and runs into the enigmatic Dr. Trevor Grant (James Callis). Since this is Eureka we're talking about, you can go ahead and assume that Carter wasn't supposed to meet the man who played Baltar in Battlestar Galactica, and that something has gone very, very wrong while Carter was out jogging. — Michael Chant

A survivalist family move to a remote area in the Midwest to prepare for the end of the world on Dec. 21, 2012, as predicted by Mayan prophecy, after their eldest daughter sees a TV program about the predictions. They swap moms with a California family in which the mother works six jobs and does the cleaning, cooking and yard work, and the father spends most of his time mentoring their 12-year-old golf-prodigy daughter. — Fred Mitchell

Longtime friends Kenny Chesney and the Steve Miller Band share the stage and chew the fat, performing each other's songs together and talking about their music. Songs include Chesney's "I Go Back" and "Living in Fast Forward," Miller's "Abracadabra" and a fun, bouncy rendition of his reggae-inflected signature song, "The Joker," to which Chesney's steel guitar player, Jim Bob Garette, contributes a tasty solo. — Fred Mitchell

The Nationwide Series goes under the lights of Chicagoland Speedway, opening a four-week Midwestern swing that may only get noticed for one night as the Danica Patrick media storm blows through the Windy City. The darling of the Indy Racing League grew up in nearby Roscoe, Illinois, but has yet to mature as a stock-car driver, finishing only as high as 30th in four NASCAR starts this year. Finishing on the lead lap in her No. 7 Chevy is a major goal as Patrick will be hard-pressed to keep up with weekly contenders such as Kyle Busch, Carl Edwards and defending champ Joey Logano. — Roger Leister

Say Yes to the Dress

Kleinfeld brides have budgets big and small, and some are just ginormous. Like Kerry, a determined client who comes to the salon with her heart set on a $21,000 Pnina Tornai gown. The staff just hopes they have it in stock. Meanwhile, the consultants have their hands full with some interesting requests this week, including a  bride-to-be who wants to look like an "Egyptian Barbie" on her wedding day, and another who needs a dress that will complement her fairy wings. — Karen Andzejewicz

On the list of things that SyFy loves, you'd find ghost-hunting reality shows, monster movies, pro wrestling, some comedy-dramas and reruns of Stephen King miniseries. Tonight, the network gets behind the horror master to launch a new supernatural drama series inspired by King's The Colorado Kid. In the opener, an FBI agent (Emily Rose) chases a prison escapee to the mysterious town of Haven, Maine, where the escapee dies an unnatural death. — Michael Chant

Wilson had an episode of his own this past season, and here, in this episode from February, it's Cuddy's turn. The dean of medicine (Lisa Edelstein) gets full day-in-the-life honors, and, not surprisingly, it's a tense and hectic day. It won't spoil anything to say that it ends well, but before it does Cuddy must deal with, among other things, arrogant insurance execs, an ER turf war and daughter Rachel's fever. Not to mention House. — Paul Droesch
