It never, ever, EVER stops raining

It's been raining for 8 days straight in my world. I've slept in beds. I've stayed awake through the night. I've restarted. Nothing stops the relentless rain. I'm so sick and tired of not being able to see anything in the snowy biomes because 50,000,000 snow particles are in my face. I'm tired of it being dark. How do you make it stop raining? 

Even last Friday, the last time I saw it stop raining, I get no real relief. It was dry for 10 whole minutes in between multi-day deluges. 

HOW. DO. YOU. MAKE. IT. STOP. RAINING?
