I too did my practice runs in custom races using the above weather patterns and each was different as each time I was starting a fresh session. In one session I got the torrential rain for the first lap, then the rest of the race was clear enough I could risk RMs. The track was damp but drivable on slicks, yet in others like on Sunday (in Div at least).
My statement about lobbies in comparison is that each time a new lobby is created, the weather pattern is randomised at creation, then held in memory such that each "reset" within the lobby, and each race started in that same lobby gets that set weather pattern. To get a new/different weather pattern, you'd need to start a new lobby. I don't think that saving the settings also saves the weather pattern, but I could be mistaken.
