I probably learned this in college as a Biology student, but I've forgotten it if I did. I'm wondering what the ideal conditions are for vibrant fall colors. I've heard from some "elder" family members that warm, dry days and crisp nights are best. Is this true, or does a moderate amount of rainfall help brighten up the leaves? I don't know why I care, but I was wondering....
Surely one of you weather folks has the answer, or maybe a random reader will know.
Thanks!
