Kielhauler, you are right, it must be something that I also noticed, that the INGAME date doesnt corespond to SHCommander Date. If I mod something in basic.cfg then I have to do it also in ShCommander?
Back to my original question: i still have weather problems, check the photo:

Check the report I just get from Watch-officer: Clouds overcast, precipitation heavy, visibility poor. Wind speed: 15m/s, which should be stromy.
Check the sky. Does it feel right?
