Hey Piper, what QMB option did you choose to get a snow storm?
Speaking of QMB fun, I just had a fun Bf-109 scramble mission with IL-2s to shoot down and vehicles to attack and I am starting to feel more and more positive about where this is all heading.
Weather and time, select overcast for clouds. Fly below the overcast and you'll have snow effects.
If you are brave, fly up through it, into the sunshine above. And if you are braver still, fly back down again, hoping that you come out in level flight, rather than in a death spiral - when I tried it, there was only about 400 m between the cloudebase and ground level. Not a lot of margin for error.
