The low temperature for each night in the mountains usually hits about 4AM. If you're camping, you may get chilly.
The sun doesn't hit until almost 9AM due to the steepness of the canyon walls, so don't lay in your tent waiting for it, we'll be off wheeling without you
Without moisture, there won't be any snow, and I don't expect any unless at high altitude. If it does, it won't accumulate enough to make a difference (unless a huge storm comes in).
Here's Engineer Pass in September 1999, after a small front came through. 10 minutes later it was sunny and warm.
Campfires really haven't been an issue for most of the Summer. The San Juans have been rained on steadily for the last 2 months, and fire danger is very low. The rain also washed out quite a few sections of trail, so it should be more fun.
All in all, I think it's going to be a beautiful week in the San Juans.
