Indeed, if you’ve seenThe Umbrella AcademySeason 2, you’ll recall that the finale takes place on Sissy’s farm, where Harlan Cooper’s powers malfunction has caused a sudden snowstorm in the middle of Dallas, Texas. Except in the original script, there was no snow. As it turns out, whenThe Umbrella Academycast and crew were filming the final episode of Season 2 in Vancouver, they were hit by an unexpected and massive snowstorm, after which the snow refused to melt. So as starEllen Pageexplains in the video below, showrunnerSteve Blackmandecided to write the snow into the episode.

You’ll see in the video that the cast also tries hard to hold their breath in scenes in the barn so as to not let their breath show how low the temperatures really were (and you’ll recall from the final episode that they didn’t really succeed). AndAidan Gallagherreveals skin-like stockings he wore to keep his legs warm during Five’s final fight.
