The forecast predicts sunny skies for Josh Lucas and Brianna Ruffalo.

The “Yellowstone” star, 54, and the Los Angeles meteorologist, 34, tied the knot in Vatican City.

“Mr. and Mrs. Incredibly blessed to receive this sacrament together inside the heart of the Catholic Church and holy city,” Ruffalo wrote on Instagram on Friday.

The weather woman’s sweet words accompanied black and white shots of her and her groom kissing, walking out of the chapel and posing in front of Saint Peter’s Basilica.

Lucas replied in the comments section, stating, “I love you! Easily one of the greatest days of my life. I am so so grateful.”

The pair exchanged vows in a private ceremony in the tiny city-state surrounded by Rome. Lucas donned a classic black tuxedo, while Ruffalo opted for a strapless lace gown.

In a second post, the blushing bride shared a close-up of herself and her partner on their special day.

“We are grateful to the many people who helped us get to this moment in the Catholic Church,” Ruffalo penned. “I am so thankful for Father Winters at the parish I grew up in, and Sister Angelica at the archdiocese of Los Angeles — as well as several others within the archdiocese.”

She added, “We also absolutely couldn’t have done this without our stellar wedding planning team who coordinated with the Vatican. Thank you for making our wedding day so beautiful and easy 🙏🏼 Thank you P & J team.”

Lucas took to his own Instagram to gush over his nuptials.

The “Sweet Home Alabama” star gave followers a glimpse behind the scenes of their wedding with adorable Instagram pics.

In one shot, Lucas is casually leaning his hand against the wall as he smiles at Ruffalo, who is holding a white lace umbrella over her head.

A second snap, in black and white, shows the actor fully leaning up against the building as the media personality struts by.

The “Palm Royale” actor and the news anchor began dating in 2022, before getting engaged last year in June.

Lucas popped the question while on a romantic getaway in Italy last summer.

“Almost 2 years ago this fall, and with no expectations, Josh walked into my life,” Ruffalo wrote on Instagram at the time, “and we knew almost immediately we had each found our person in a way we’ve never experienced — on every level.”

“This was the easiest and best question I’ve ever answered,” she continued. “So, here’s to forever with my love, my best friend. I can’t wait to keep living this life with you.”

Lucas echoed his partner’s sentiments, writing in his own post, “For the last 2 years in Every Way and Every Day this beautiful soul has made me and my life better, deeper, and more whole.”

“I am so grateful and thrilled she said ‘Yes.’ I WAY love you, Brianna. Thank you to our families and all the people and places that made this come true. I am absolutely aware I got crazy lucky.”

Lucas was married to Jessica Ciencin Henriquez from 2012 to 2014. The exes have a son, Noah, 13.

In 2022, the actor spoke about having his mini-me on set in Montana while filming the Western “Yellowstone.”

“To bring him on set and have him there, we had a great day, a rather, I must say, humbling day for me,” Lucas told “Entertainment Tonight.” “It was the scene early in this season where I knock a guy out.”

On the series, which ran for five seasons from 2018 to 2024, Lucas played the younger version of Kevin Costner’s John Dutton.

“My son was sitting at the monitor,” Lucas continued. “I walked up to the guy to punch him and, frankly, I tripped. My hat fell off and I dropped my gun. My son screamed from the monitor. He was like, ‘Dad, you’re a fool!'”

Although Lucas has largely kept his son out of the spotlight, he did share in 2019 that Noah’s first kiss was with a fellow A-lister’s daughter.

Noah shared a smooch with Luna Thurman-Busson, Uma Thurman’s daughter, while their parents were working together in the 2017 Broadway show “The Parisian Woman.”

“Backstage, [Noah and Luna] had their little playroom, and one day we opened the playroom and they both like popped up from behind the couch, both of them. And they were both obviously so nervous,” Lucas explained while on “The Late Late Show With James Corden.” “Luna, Uma’s daughter, walked out, and I took Noah and was like, ‘What’s going on?'”

“He was like, ‘I think, I guess I just had my first kiss,'” the actor added. “Think about that — your first kiss is backstage behind a couch in a Broadway theater.”
