I'm glad somebody else is on the project. I cannot exaggerate how many hours I've spent researching and still can't find the answer.Your question intrigued me, so I thought I'd test some things this morning before heading off to the office.
I did a couple of custom 10 minute races at COTA and customized the weather - which I've never really done in the past.
I enabled Dynamic Weather, set the variability to 33% and enabled Random Weather.
Result: the race started in the sun and finished overcast. Seeing the weather change, I then set the variability to 75% to find out if I'd get even more change.
Result: the race started sunny and ended sunny and I didn't really see much change.
Granted, this was only a small sample based on having a few extra minutes to spare. I'll have to try longer races at some point, along with playing with more settings.

If you make the cloud cover slider 60% or more you will get rain but I don't want to start the race in rain.
I want to start the race with nice weather and then have it rain which forces everybody to pit for new tires and then have the race end in nice weather, hopefully to force everyone to pit to get slicks again. When I say everyone I'm referring to the AI because I usually only play offline.
I did try a high variability number without touching the cloud cover or precipitation. The race started dry and within half a lap to 3/4 of a lap it started raining.
I'll keep trying to figure out how to make this happen.
