It's official -- the filmed-in-Portland series "Grimm" will end with Season 6. Today, NBC announced the fantasy-crime procedural will return for its sixth and final season Friday, Jan. 6, 2017.

"Grimm" celebrated its 100th episode last season. But the network deciding not to renew it for Season 7 was expected, when NBC renewed the show for a shortened Season 6.

From the NBC press release:

"Closing out an incredibly successful series run and giving viewers a chance to say goodbye over the last 13 episodes, the sixth and final season of NBC's drama 'Grimm' will begin its last chapter with the battle fans have long been waiting for -- Nick versus Capt. Renard."

In terms of the final season, here's an idea of what we can expect:

"...the nefarious forces of Black Claw have been silenced and Nick (David Giuntoli) faces an all too familiar foe in Capt. Sean Renard (Sasha Roiz). Now in the seat of power as the mayor elect of Portland, Renard is poised to bring rise to his own brand of law and order. Nick must take a stand to protect his city and those closest to him, especially his child with Adalind (Claire Coffee). It will take the full force of Nick and his allies to find a way to bring the peace.



Meanwhile, Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) grapple with bringing a child into a new and tumultuous world, and Eve (Bitsie Tulloch) faces unsettling identity issues as her former self lurks below the surface."

The series, which is set in Portland and has filmed here since it started, in 2011, received a renewal for Season 6 earlier this year. But when NBC cut back the number of episodes ordered from the customary 22 to 13, it seemed apparent that this would be the final season for "Grimm."

When I asked Robert Greenblatt, NBC Entertainment chairman, about whether this would be the last season for "Grimm" at the recent Television Critics Association summer press tour, Greenblatt said, "We haven't decided that yet."

But now they have. Fans will also be waiting longer for the final season of "Grimm" to begin, since the show has in the past generally premiered in October. And for its final season, "Grimm" will air an hour earlier, at 8 p.m. Fridays.

As the Hollywood Reporter notes, "'Grimm' entered the 2016-17 broadcast season as NBC's second-longest running series, behind 'Law & Order: SVU,' which is entering its 18th season."

Deadline reports that "'Grimm' had been the little engine that could, an under-the-radar show that became a breakout during the 2011-2012 season despite airing on Fridays. It was the first series launched by the current NBC regime to stick. Last season, the supernatural procedural averaged a 1.6 most current adults 18-49 rating and 6.0 million viewers. That was down from the Season 5 averages (2.0, 7.1), but 'Grimm' still ranked as one of the highest-rated scripted series on Friday despite being a self-starter, with very little lead-in support. It also is owned by NBC and does well internationally."
