Arrow and Supergirl will move nights this fall as The CW expands its programming schedule to include Sundays.

Released this morning ahead of the network's upfront presentation in New York City, the 2018-2019 lineup sees Arrow paired with DC's Legends of Tomorrow on Monday, and Supergirl soaring to Sunday to lead off the new night of television.

The Flash and Black Lightning will remain on Tuesdays, Riverdale on Wednesdays, and Supernatural on Thursdays. The 100 and iZombie will return at midseason.

The CW's reclaiming of Sunday nights -- it ceded the block in 2009 to local affiliates -- gives the network two additional hours of programming a week, allowing for a little more flexibility. A reluctance to run more than four superhero shows at a time had led Supergirl and Legends of Tomorrow to share a Monday time slot in the second half of this season, to the displeasure of viewers.

Here's The CW's fall 2018 schedule:

8:00-9:00 PM SUPERGIRL (New Night)
