Josephine Bornebusch and Greg Poehler star in “Welcome to Sweden”

There's a chill in the air, there's snow on the ground and hoods are pulled low on parkas to keep out the cold. What? No, it's still July. You didn't miss summer, which is a good thing because season 2 of the Greg Poehler-starring sitcom "Welcome to Sweden" premieres Sunday, July 19, on NBC.

Season 2 kicks off six months after Poehler's character, Bruce, first moved to Sweden with his girlfriend, Emma (Josephine Bornebusch, "The Dog Trick," 2002), and it's now the dead of winter. Hilarity abounds as the former accountant continues to adjust to his new fish-out-of-water life this season, and on top of just trying to fit in in Sweden, he has another occasion to handle -- his engagement!

Yes, Bruce -- who is modeled very closely after Poehler and his real-life experiences -- is getting ready to propose to Emma, and season 2 follows the engagement journey as the couple deals with customs, family and career transitions. Poehler is already married to his Swedish wife, Charlotta, and they have three children -- which may be a bit of a sign of what's to come.

Of course, when you're writing from personal experience, as Poehler does for "Welcome to Sweden," it can be a little offputting to have your life thrown up on screen for everyone to see, especially for loved ones. As Poehler said in an interview with "The Sydney Morning Herald," outside of things that happen directly to him, most of the other relationships in the show are highly fictionalized.

"I [told] my friends and family that it's all fiction and it has nothing to do with them," he said. "But when it comes to the relationship [between Bruce and Emma], there are certain things that are off limits. Most of Bruce's experiences when he's out in Sweden -- the fish-out-of-water, culture clash moments -- are stuff that has happened to me. Whereas the relationship [with Emma] is mostly fictionalized. That makes it easier for me to sleep in the same bed as my wife."

A former lawyer, Poehler up and quit his job after 12 years to chase his stand-up comedy dream in Sweden. Penning the script for the show in his attic, he was soon joined by his famous sister, Amy Poehler ("Parks and Recreation," "Saturday Night Live"), who hopped on board to executive produce, and the rest, as they say, is history.

Poehler also says his wife, Charlotta, has been more than supportive throughout the process of bringing "Welcome to Sweden" to life, especially since he took a rather unconventional route to stardom.

"The second season has been a lot easier for her to adjust to," he said in the "Sydney Morning Herald" interview. "The first season was a bigger adjustment. I think for her it was difficult. ... It's one thing to marry an actor, but for someone to become an actor is something else. She's been very supportive, and I think you need certain people to believe in you before anybody else does."

The cast of “Welcome to Sweden”

Poehler and Bornebusch are joined in the show by a host of other very funny people. Lena Olin ("Alias," "The Ninth Gate," 1999) stars as Emma's very opinionated mother, Viveka; Swedish comedian Claes Månsson ("Lorry," "Heartbreak Hotel," 2006) stars as Emma's father; and Christopher Wagelin ("The Circle," 2015) stars as Emma's freeloading brother who desperately needs to move out of his parents' house. On Bruce's side, Illeana Douglas ("Goodfellas," 1990) stars as his mother, Nancy, and Patrick Duffy ("Dallas") stars as his father, Wayne.

"Welcome to Sweden" also boasts a very impressive guest cast, as Bruce's past celebrity clientele pop up every so often. Season 1 saw the likes of Will Ferrell ("Step Brothers," 2008), Malin Åkerman ("Trophy Wife"), Gene Simmons ("Gene Simmons: Family Jewels"), Aubrey Plaza ("Parks and Recreation") and Amy Poehler make appearances. Season 2 features even more guest stars, including Poehler and Plaza -- who continue their roles as themselves -- as well as Jack Black ("Kung Fu Panda," 2008), Jason Priestley ("Beverly Hills, 90210"), musician Paul Simon ("Annie Hall," 1977) and Neve Campbell ("Scream," 1996).

Season 2 has already premiered -- and wrapped up -- overseas in Sweden, so spoilers are floating about everywhere online. (Tip: avoid the "Welcome to Sweden" Wikipedia page.) Numbers for the show have steadily declined since its season 1 premiere, both in Sweden and stateside, making it a tossup to see if the series will be renewed for a third season. It has the power to surprise, however, especially since TV4 -- the show's Swedish network -- was quick to order a second season last year.

Winter is coming! Thankfully for us, it's not for a while. For the cast of "Welcome to Sweden," however, it's all parkas, snow and cold as season 2 comes stateside. Picking up in the dead of winter six months after Greg Poehler's Bruce moves to Sweden for the woman he loves, the show follows Bruce and Emma as they navigate a new engagement and the craziness that comes along with it. Catch the season 2 premiere of the hilarious sitcom "Welcome to Sweden" when it premieres Sunday, July 19, on NBC.
