I have a suggestion to you Skweetis,
And i hopes that could be a good one.
IN GWX I set the weather to be more frequently changed by the game with more probability to change in all environments. The main problem in ShIII is that the game reset the time counter when you save reload and also that if you use large interval or choose to have no changes on environments...well, you will frequently have long, very long time without any weather change in game.
So, with these two main problems in mind, can you make a randomize that only mess with the weather state when you start a patrol (sometimes raining, sometimes bad weather, sometimes a clean day, etc...) but preserving the short (with a few range random) weather probability to change during the patrol?
What I mean is that you could maintain the Weather Change Interval at 5-7 for example and the Weather main variable adjust to have clouds, sun or rain at the start of patrol, the wind no more than 6 at start of patrol and the environments settings (cloud, precipitation, fog and wind) at least at small variation and sometimes at heavy variation. The final result could be a always variable weather condition when starting a patrol but also with a great probability to have always changes on weather state during the patrol, avoiding that so long fixed weather.
I'm saying all this because the Weather mod is great but as it is now sometimes it adjust the weather to have a long and almost fixed weather during the patrol because sometimes uses "rigid" environment variables as a choice (for example long interval in hours or no "changes" option for the environment).
Hopes that you understand me and my english!
And keep up the good work mate!
