The Dunphy family will meet a local weatherman when "Modern Family" returns for season 8.

Deadline revealed that former "Castle" lead star Nathan Fillion will join the cast of the critically acclaimed comedy series in a recurring role next season. Fillion will reportedly play the role of local weatherman named Rainor Shine, as confirmed by series co-creator Steve Levitan during the Television Critics Association panel.

"Nathan Fillion is going to do an arc for us this year," Levitan said, "playing a local TV weatherman who gets involved with the Dunphy family."

The series co-creator also dropped a major teaser for the premiere episode of season 8.

"Oh, we're going to start, the premiere will be in New York, or some of the premiere takes place in New York and we'll be shooting some of that in New York. And we're doing a Halloween episode this year," he stated, as reported by Movie Fone.

The eighth season of "Modern Family" is also expected to deal with a lot of storylines, such as the return of Mitch (Jesse Tyler Ferguson), Cam (Eric Stonestreet) and their daughter Lily (Aubrey Emmons) after spending their vacation in Kansas. Cam and Mitch's relationship will also be tested because of the opinion of Cam's grandmother.

The series co-creator also clarified that they are not yet thinking of ways to end the show at the moment.

"I haven't really thought too hard about the ending of this show yet, because I don't even know where we'll be at that point," Levitan stated. "So I think that that'll just come very organically at the time. I imagine it'll be some sort of an event, but I don't know what yet. There's a lot of people that will be thinking about that, and it'll be a big, big discussion on that year when we're finally wrapping things up."

ABC will air the premiere episode of "Modern Family" season 8 on Wednesday, Sept. 21.
