Weather forecast for November, Sheffield These are just general weather checks as November is one month away so it cant be 100% correct so I will do a further weather check closer to the time. Its important to have the right weather conditions while filming as you don’t want it to be raining in a scene where its described as being sunny. Especially weather has connotations and sets certain moods. For example: during funeral scenes its always dark and gloomy/raining and cheerful scenes like someone getting a new job would be bright and sunny. So therefore weather conditions have to be perfect in order for you to have the effect on the audience you intend to.
