Chicago Fire actress Molly Glynn died this weekend after getting caught in a fast-moving storm during a Friday afternoon bicycle ride in Chicago.

Glynn, who was also a veteran stage actress, was on a bike ride with her husband, Joe Foust, when a fast-moving storm uprooted a tree near the path they were traveling.

According to the Chicago Tribune:

Foust, 45, said he and Glynn would bike frequently together. On Friday, they were riding on their favorite biking trail, the North Branch, and were about 25 miles into the ride, heading south on the trail, when the weather suddenly changed around 3 p.m. as they approached Willow Road.

"It was harsh and quick," said Foust, who has been married to Glynn for about four years.

Glynn, who was riding behind Foust, yelled that the two should take cover. A split second later, Foust said he heard a loud crack and saw a tree fall down behind him in the rear-view mirror of his bicycle. One of the branches hit Foust's back, but he said he is doing fine.

He said Glynn wore a helmet.

Glynn died from her injuries Saturday in the hospital. She was 46.

"I couldn't save her. I couldn't save her. She's gone," Foust, wrote in a Facebook message.

"Molly was a marvelous actress and a completely warm hearted and generous human being. She had grace, sophistication and a sparkling, sexy, sassy stage presence," Michael Halberstam, the artistic director at Chicago's Writers Theatre told CBS. "She could transform from a princess to a flower girl in the twinkling of an eye. She was a loving mother and wife and everyone who met her fell in love with her."

Foust wrote Sunday that her organs had been donated.
