There are exceptions to all of these various suggestions, a technique that is rarely employed where you use the weather as a character. It's not always done well--since it's done so infrequently--but it's an interesting twist. I've only done it once, but I loved the overall feel it gave to the book.
Essentially, before any given scene/chapter/section, the weather—just as a fitting epigraph—captures the mood of the coming chapter. Thus, if things are going to take a sudden downturn in the story, and everything's about to go to shit, you spend a few lines with the primary character reflecting on the weather, and how it impacts their outlook/mood.
A few examples, in the Prologue, just before he's murdered, the victim of the investigation opens with the following reflections:
Councilman Adrian Adams rushed up the steep steps to the carefully maintained brownstone and slammed the heavy oak door behind him, blocking out the howling wind and icy sleet. He paused a moment to catch his breath.
"Damn, it's miserable tonight," he muttered to himself as he set his dripping umbrella on the tiled floor. "This friggin' umbrella is useless. The sleet's blowing sideways!" He glanced up the narrow stairway while he unbuttoned his dripping coat.
In the very next chapter, we're introduced to the protagonist police detective at the start of the first chapter, where the weather description is a bit more involved:
Em ignored the sleet lashing the windows, the rattling glass nearly overwhelming her voice. She curled her hair around her finger as she listened to the phone. The unsettling weather portended a more severe approaching storm.
"So how about we get together tonight? Say a nice dinner, a little wine; maybe a little romance?"
Em hoped an incoming low pressure system pelting the windows would create a temporary respite in homicides, her occupational specialty. But she knew death waits for no one. The mix of rain, sleet and lightning it created, produced anger and frustrations, and malice directed inward turns domestic. This storm, like the momentary lull in her personal life, was but a harbinger of bigger things to come. But for now, as the storm outside settled into a steady downpour, it was nice focusing on friendlier diversions between her other assignments.
It's an interesting technique, and
not a 'one and done' event. But despite how much I enjoyed it (the technique, the effect
and the book), one book was enough for me, and I've never tried repeating it. After all, I don't want to become known as the
inventor of "Weather Porn"! ;)
