Make weather change in believable steps and stay long enough to notice

Left to chance, the sky jumps from a clear day to a storm and back within an hour, and snow falls in midsummer. Here is a filter that takes any stream of random weather picks and turns it into weather with sensible neighbours, a minimum stay for each kind, and seasons that ban some kinds.

Why this works

Weather has a memory: it moves from one state to a nearby one and stays a while. Letting a chance draw only propose a change, and a few plain rules accept it, gives variety without the jumps that make the sky look broken.

When not to use it

Skip it in a game where the weather is a story event, set by hand, or in a stylised world where sudden change is part of the charm, such as a cartoon with a storm for each mood. Then keep your own script.
