The CW previously announced dates for the series' midseason returns: Supergirl on Monday, Jan. 15, The Flash on Tuesday, Jan. 16, Riverdale on Wednesday, Jan. 17, and Arrow on Thursday, Jan. 18. The series premiere of Black Lightning will air Tuesday, Jan. 16, following The Flash, pushing the return of Legends of Tomorrow until later.
It's worth noting that while many shows will move on Thanksgiving to make room for holiday programming, or else air repeats, Arrow will have a new episode, appropriately titled "Thanksgiving": "Oliver (Stephen Amell) celebrates Thanksgiving with his family but the happy moment is interrupted. Meanwhile, Black Siren (Katie Cassidy) returns to wreak havoc on the holiday."
