I know this thread's a bit dated, and it's unlikely that anyone here will get any notifications, but my region of my singleplayer world (1.18.15 stable) has had over 10 days of unbroken rainfall, and there's no command to get it to stop raining.
It has easily doubled or tripled the time required for my meager few crops, berry bushes, and trees to grow, and I'd really like to see clear skies again.
The precipitation rating has not gone above "very common" since this rain started, and I'm thinking my save may have run into a minor bug.
