Weather/Rain/Snow re-appears after using /weather clear

So, I was on my minecraft creative world and it started to snow when I didn't want it too, so i obviously do /weather clear and it stops. But then fast forward like 5 minutes it snows again, so I do /weather clear again and it stops again. Repeat this process a few more times in about the same amount of time, (5-7 minutes) So, finally I go to bed which clears the rain manually when you wake up and a few minutes, maybe even 30 minutes later no rain. This same process happened a few times after this on the same world, and even on a different world too.
