Help with my wether system

Search on the web for this but not found any solution for it . I try here :).
Is it possible to have a weather system that chance overtime ? :). Let’s say you want the weather to go from Sonny to it begin to rain :D. Any tip how to set this up? :). Can you use partical? I don’t know if you can do a partical system that’s turns on just sometimes :stuck_out_tongue:

it’s just rain and Sonny now but I want to be able to expand it with storm , lighting , snow :slight_smile:
