Most effective way to sync weather ? EX - Snow?

Hey guys, I was wondering how to sync snow so that when people leave the server and rejoin, it is still enabled.

If everyone is in the server and I toggle it via a trainer, everyone can see it. However, if they leave and rejoin it is gone.

This is the best way in my opinion without a doubt. It controls and syncs weather, time, traffic and peds.

If you prefer an active project, an alternative to ACL could be these two combined:

Weather/time sync

Peds/Traffic density sync + other stuff
