I think this would be good for both practical or story-telling use. For example if you're trying to decorate a house but it's raining at night, you could clear the weather and set the time to morning to make it easier to see. If you wanted to create a spooky themed house, you could set the time to night and the weather to foggy.
I made a simple edit. It's not perfect but hopefully it can showcase my idea a bit better.
