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

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

“Mr. and Mrs., incredibly grateful to have received this sacrament together in the heart of the Catholic Church and the holy city,” Ruffalo shared on Instagram on Friday.

The weatherman’s touching words were paired with black and white photos showing him and his spouse sharing a kiss, leaving the chapel, and posing in front of the stunning structure.

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 Italy. Lucas donned a classic black tuxedo, while Ruffalo opted for a lace, strapless gown.

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

“We appreciate all those who assisted us in reaching this moment in the Catholic Church,” Ruffalo expressed. “I’m especially thankful for Father Winters from the parish of my childhood, Sister Angelica from the Los Angeles archdiocese, and 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” vet gave followers a glimpse into the 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 laced 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” star and news anchor began dating in 2022, before getting engaged in June 2024.

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 previously married to Jessica Clencin Henriquez from 2012 to 2014. The exes share 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, the “Firm” star 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, Uma Thurman’s daughter, while their parents were worked 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.”
