The only option is to make a script yourself. SF got an adv time-function that synchronises most functions to make as less network as possible.

StormFox.SetWeather(<string>,<amount 0-1>)

As a note. Weather changes instantly at timespeed 0.

i did different, in map options i did the night be as bright as the day, and i'm ignoring the black sky LOL i play with friends in big maps kinda of sniper battles with the wind and etc, it's funny
thanks for the great mod.
