Very simple mod designed mainly for those who are tired of 90% sunny weather in Los Santos. With this mod weather will change more, which means it will be rainy, foggy, cloudy and etc more often than usual. Tweaked duration a bit for some weather types as well. As a bonus I added light snow, it has pretty low chance to trigger and won't drag for too long (screenshot 3). Looks pretty natural and cool I think.

I haven't rewritten or altered any weathers as in some graphic mods, only tweaked chances and duration.

Particularly, if someone is curious, there's a list of vanilla weather chances comparison to my mod (vanilla - v, mod - m):

EXTRASUNNY - v56 - m30
CLEAR - v35 - m30
CLEARING - v2 - m10
SMOG - v39 - m20
CLOUDS - v11 - m20
FOGGY - v6 - m16
OVERCAST - v13 - m18
RAIN - v3 - m18
THUNDER - v3 - m9
SNOWLIGHT - v0 - m1

As you can see extra sunny, clear and smog has ridiculously high chances in vanilla in comparison to other weather types. I kept sunny weathers ratio higher not to make it rainy, foggy and etc all the time, and I think it works quite well.

Installation:
- Obviously you need latest script hook.
- Use OpenIV and navigate to your *GTA V Root Folder*\mods\update\update.rpf\common\data\levels\gta5
- Replace weather.xml file

To uninstall, just navigate to the same path and remove or replace weather.xml file with original.

Have been playing with it for a couple of weeks now, no issues or inconsistencies detected. Report if you encounter something.

P.S. As most other mods, don't try using it online to be safe.
