I'd like to gather opinion on including the weather, be that in the narrative or mentioned by a character. I can imagine many writing tutors would say leave it out unless it impacts on the plot in some way. But I don't agree. In fact I think that's stupid advice. I'm not talking about the characters having a two-page dialogue about the weather, or using purple prose to describe it at length in the narrative, but aren't we as writers supposed to be painting a picture? Creating atmosphere? From a reader's perspective, are you blind to mentions of weather, or do you feel it adds to the immersion of the story?
