Don’t hesitate to let the weather help you set the tone of your story or novel. Often in good fiction what’s going on outside is reflective of what’s happening inside of characters and plots.
The location and time frame of your story is more than just a stage for your characters to tromp around on. In some cases, the setting becomes a character itself.
It must be believable and sufficiently described to be as real for your readers as the rooms they are sitting in when reading it.
Before you can work one bit of the magic in that story or those characters, you have to make your readers fully aware of the place and the time, of what the weather is like, what things look like, smell like, and feel like.
PUTTING THE READER IN THE SETTING
Giving the Lay of the Land – This pure telling rather than showing, a topic that we’ll take up in chapter four. It is reportage.
Using Intricate Details – The detailed approach might be a good way for you to bring your reader into your story, to carefully paint a mental picture-down to the texture and shapes of seemingly unimportant things – and establish in the reader’s mind an image as clear and focused as a good photograph.
*The best solution is to keep your type of reader in mind all the time, and follow the clutter rule: If something isn’t serving the advancement of the story, it needs to go.
