The fall TV season is coming to an end, which means one thing: time to look ahead at what's coming in the midseason. The CW has released a rundown of the important dates in its midseason lineup, and they reveal that Supernatural is getting at least one last time slot switch before the end, Arrow's grand finale isn't too far off, and some long-awaited premieres are in store.

While Supernatural will end in the 2019-2020 TV season, let's start with the end of Arrow, as that isn't too far in the future at this point. The series that started the entire Arrow-verse will return for its first non-crossover episode of 2020 (presumably the spinoff backdoor pilot) on Tuesday, January 21 at 8 p.m. ET, with its series finale to air the next week.

The series finale on Tuesday, January 28 will actually be a two-hour event, with a finale preview kicking things off in the 8 p.m. ET hour and then the last episode debuting at 9 p.m. ET.

As for Supernatural, fans won't lose that series quite as early in 2020 as Arrow. It will occupy a new time slot until the series finale, which releases on Monday, May 18. Supernatural has made history in more than one way over the 15 seasons of its run, so the series finale should be must-see TV.

Now, what is Supernatural's new time slot, what new is coming to The CW, and what superheroes will be back? Read on to find out!

Note: all times are in ET, and shows in all caps are new to The CW.

Tuesday, January 218 p.m. - Arrow9 p.m. - Legends of Tomorrow Season 5 PremiereThursday, February 68 p.m. - KATY KEENE Series Premiere9 p.m. - LegaciesMonday, March 168 p.m. - Supernatural (New Time Slot)9 p.m. - Roswell, New Mexico Season 2 Premiere

Supernatural kicked off Season 15 in the 8 p.m. ET time slot on Thursday nights, and it will lose that slot to the first season of Riverdale spinoff Katy Keene in midseason 2020. Instead, starting in March, Supernatural's new episodes will air in the 8 p.m. ET time slot on Monday nights, which is currently held by All American and followed by Black Lightning.

All American and Black Lightning air their season finales the week previous, ending their current runs on March 9. Interestingly, the first concrete connection between Black Lightning and the Arrow-verse will take place prior to that March 9 finale.

The two-hour finale sendoff for Arrow on January 28 means that Legends of Tomorrow will already go on a break for a week after its Season 5 premiere. The show, which was bumped to the midseason, will have been off the air for quite a while, so fans of Legends who don't necessarily watch Arrow may not be thrilled about the off week. Still, there will be plenty of Arrow-verse action thanks to the "Crisis on Infinite Earths" crossover, which will incorporate Legends.

Arrow-verse fans on the whole may wonder why The Flash, Supergirl, and Batwoman aren't listed among the midseason premieres. Considering the broadcast date for the final two legs of "Crisis on Infinite Earths," it's probably safe to say that they'll be back following the end of the crossover, with The Flash presumably hitting the airwaves paired with Legends of Tomorrow after Arrow's grand finale.

So, when will the five-show Arrow-verse crossover known as "Crisis on Infinite Earths" hit the airwaves? Unfortunately for fans, the five episodes will be split between the end of 2019 and the beginning of 2020 by more than a month. Read on for the dates:

Sunday, December 88 p.m. - SupergirlMonday, December 98 p.m. - BatwomanTuesday, December 108 p.m. - The FlashTuesday, January 148 p.m. ET - Arrow9 p.m. ET - Legends of Tomorrow

"Crisis" will wrap with the only two-hour block of the crossover, and it should be a doozy of a night. It's still not quite clear what's going to happen to Oliver, as the Arrow-verse is still trying to sell Oliver's death but the Arrow Season 7 finale revealed that Oliver is alive, but elsewhere.

Then again, The Monitor has also said that The Flash needs to die, which Oliver does not know about, so not a lot seems to be set in stone other than that Lyla is going to have some things to answer for once her secret comes out. All signs point toward people in the Arrow-verse at least thinking Oliver is dead, but fans may be waiting until January 14 to get any solid answers.

All of this said, premieres are still a ways off, and you can still find new episodes of Supernatural, the Arrow-verse (aside from Legends of Tomorrow) and more airing in primetime on The CW. Be sure to tune in if you don't want to miss a moment of your favorites!
