Weather can indeed play an integral role in a plot. In fact, I just had a short story published in an anthology called Snowbound Hearts. My story is called Sophie’s Snow Day and the tag line is A snowstorm can be a life changing event. Just ask Sophie. In this story, a snow storm really did change someone’s life.
I have a friend writing a novel right now where a hurricane is an essential part of her story and I gave her a quip to use in it. “He came over to batten down and got bedded down.” I said it to her in an email and she asked if she could use it in the story and of course, I obliged.
A warm, sunny day plays a really important part in one of my novels that will probably never see the light of day. It’s a pretty good story after the first chapter but I have fiddled and fiddled with that beginning for years and can’t get it like I want it. So, you’ll just have to trust me on my statement that the warm day plays a role early in the book and things that happened on that sunny day arise yet again in the end of the story.
I like to use weather almost like another character. Streaming rain, hailstones, mud, rainbows and wind can all help build the immediacy of the scene and I believe it helps to bring the reader deeper into the action. What do you think? Do you like to read about the weather in the stories you read or does it not matter?
