“Supergirl” will land in its familiar Monday 8 p.m. time slot when the drama relocates from CBS to the CW in the fall.

The DC Comics superhero series will be paired on the night with the third season of CW’s “Jane the Virgin,” in what the network called the union of a woman with superpowers and an “everyday superwoman.” “We think ‘Supergirl’ will give a real boost to ‘Jane the Virgin,’ ” CW chief Mark Pedowitz said.

Meanwhile, new romantic comedy “No Tomorrow” lands the coveted Tuesday 9 p.m. slot behind CW’s highest-rated series, “The Flash.” Pedowitz said the offbeat show about a romance that blooms as the apocalypse draws near “shares with ‘The Flash’ a blue-sky optimism” that made it a good fit for the time slot.

CW has ordered four new dramas for the 2016-17 campaign (see listings below), with three settling onto the fall schedule. “Riverdale,” uber-producer Greg Berlanti’s contemporary spin on the Archie Comics milieu, will be on the bench for midseason, along with returning dramas “iZombie,” “Reign,” “The 100” and “The Originals.”

Pedowitz noted that fall 2016 marks the 10th on-air anniversary of the network formed by the merger of the WB Network and UPN. CW’s second decade begins “from a position of strength,” he said after a solid 2015-16 season.

On Wednesday, “Arrow” remains the 8 p.m. anchor, paired with new drama “Frequency.” The former occupant of that slot, “Supernatural,” moves to Thursday 9 p.m. behind “D.C.’s Legends of Tomorrow.”

On Friday, the second season of “Crazy Ex-Girlfriend” moves from the Monday lead-off slot to 9 p.m. behind “The Vampire Diaries.”

Among other initiatives, CW said it was planning a big distribution boost for its free streaming app starting in the fall, when it will be available to a potential install base of 80 million devices. The ad-supported app offers authentication-free access to the five most recent episodes of CW’s current series at any given time.

And it is planning to launch a new vertical dubbed “CW Good” on its CWTV.com platform in August, anchored by a new docu-series “My Last Days.” The series produced by “Jane the Virgin’s” Justin Baldoni documents the stories of “six real-life superheroes” facing death who determined to make an impact on others in the time they have left. The series hails from Wayfarer Entertainment and Rainn Wilson’s SoulPancake banner.

NO TOMORROW

Evie Callahan (Tori Anderson), a risk-averse quality-control assessor, appreciates order. Whenever she’s making a list, “make a list” is both the first thing on it and the first thing crossed off. Such a regimented life has its drawbacks. Her on-again/off-again romance with the sweet, but soft-spoken Timothy (Jesse Rath) has sputtered out. Her career has stalled. Her boss, Deirdre (Amy Pietz), a petty tyrant with breath that could kill a plant, laughs off her ambitions. Then Evie meets charming,free-spirited Xavier Holliday (Joshua Sasse), and the attraction is immediate and electric. He brings a jolt of joyful, rollicking romance into her life.Xavier encourages Evie to carpe that diem, because it’s more fun that way and because, well, the apocalypse is, you know, nigh. He believes humankind has a mere eight months and twelve days until a runaway asteroid smacks us all into stardust. That’s why he made an Apocalyst – a tally of every last thing he wants to do before the world goes kaput. So with the help of her friends – Hank(Jonathan Langdon), a diehard conspiracy theorist, and Kareema (Sarayu Blue), a droll nihilist – Evie must decide whether Xavier is certifiable and whether that even matters, if being with him means living her life more fully. Based on the International Emmy-nominated Brazilian format from Grupo Globo, NO TOMORROW is a romantic comedy with the ultimate ticking clock. NO TOMORROW is from CBS Television Studios and Warner Bros. Television in association with Electus,with executive producers Corinne Brinkerhoff (“American Gothic,” “Jane TheVirgin,” “The Good Wife”), Maggie Friedman (“Witches of East End”) and Ben Silverman (“Jane The Virgin,” “The Office”).

FREQUENCY

Detective Raimy Sullivan (Peyton List) has always wanted to prove that she is nothing like her father. In 1996, when Raimy was eight years old, NYPD Officer Frank Sullivan (Riley Smith) left Raimy and her mother, Julie (Devin Kelley), behind when he went deep undercover, got corrupted, and got himself killed. Or so the story has always gone. Few people knew about the secret undercover sting operation Frank was really charged with, led by Stan Moreno (Anthony Ruivivar),who has now risen to Deputy Chief of Police. Frank’s former partner, Lieutenant Satch Reyna (Mekhi Phifer), is now Raimy’s mentor and friend, and he has urged her to let go of the hurt and anger she still feels about Frank’s disappearance and death, but the old pain still lingers. Raimy can barely bring herself to discuss Frank, even with her devoted boyfriend, Daniel (Daniel Bonjour), or her childhood friend, Gordo (Lenny Jacobson). Now, twenty years later, Raimy is stunned when a voice suddenly crackles through her father’s old, long-broken ham radio – it’s Frank, somehow transmitting over the airwaves and through the decades from 1996. They’re both shocked and confused, but Raimy shakes Frank to the core when she warns him that the secret sting he is undertaking will lead to his death. Armed with that knowledge, Frank survives the attempt on his life. But changing history has dramatically affected Raimy’s life in the present – and there have been tragic consequences. Separated by twenty years, father and daughter have reunited on a frequency only they can hear, but can they rewrite the story of their lives without risking everyone they love? FREQUENCY is from Warner Bros. Television in association with Lin Pictures,with executive producers Jeremy Carver (“Supernatural”), Toby Emmerich (“The Notebook” feature film), John Rickard (“Horrible Bosses”), Dan Lin (“The LEGO™ Movie,” “Sherlock Holmes”) and Jennifer Gwartz (“Veronica Mars”).

RIVERDALE

As a new school year begins, the town of Riverdale is reeling from the recent, tragic death of high school golden boy Jason Blossom — and nothing feels the same… Archie Andrews (KJApa) is still the all-American teen, but the summer’s events made him realize that he wants to pursue a career in music — not follow in his dad’s footsteps—despite the sudden end of his forbidden relationship with Riverdale’s young music teacher, Ms.Grundy (Sarah Habel). Which means Archie doesn’t have anyone who will mentor him — certainly not singer Josie McCoy (Ashleigh Murray), who is only focused on her band, the soon-to-be-world-famous Pussycats. It’s all weighing heavily on Archie’s mind — as is his fractured friendship with budding writer and fellow classmate Jughead Jones (Cole Sprouse). Meanwhile, girl-next-door BettyCooper (Lili Reinhart) is anxious to see her crush Archie after being away all summer, but she’s not quite ready to reveal her true feelings to him. AndBetty’s nerves – which are hardly soothed by her overbearing mother Alice (Mädchen Amick) aren’t the only thing holding her back. When a new student,Veronica Lodge (Camila Mendes), arrives in town from New York with her motherHermione (Marisol Nichols), there’s an undeniable spark between her and Archie,even though Veronica doesn’t want to risk her new friendship with Betty by making a play for Archie. And then there’s Cheryl Blossom (Madelaine Petsch)…Riverdale’s Queen Bee is happy to stir up trouble amongst Archie, Betty, andVeronica, but Cheryl is keeping secrets of her own. What, exactly, is she hiding about the mysterious death of her twin brother, Jason? Riverdale may look like a quiet, sleepy town, but there are dangers in the shadows… Based on the characters from Archie Comics, RIVERDALE is from Warner Bros. Television and CBS Television Studios, in association with Berlanti Productions, with executive producers Roberto Aguirre-Sacasa (“Supergirl,” “Glee”), Greg Berlanti (“Arrow,” “The Flash,” “Supergirl,” “DC’s Legends of Tomorrow”), Sarah Schechter (“Arrow,” “The Flash,” “Supergirl,” “DC’s Legends of Tomorrow”) andJon Goldwater (Archie Comics).
