In spring, plants sprout , tree leaves unfurl , and flowers blossom. Summer is the warmest time of the year and has the most daylight, so plants grow quickly.
In autumn, temperatures drop, and many trees lose their leaves. The four-season year is typical only in the mid-latitudes. The mid-latitudes are places that are neither near the poles nor near the Equator.
The farther north you go, the bigger the differences in the seasons. Helsinki, Finland, sees In mid-December, however, it is light for less than 6 hours.

Lows should be from 35 F to 45 F.
Deciduous trees and other plants should be changing colors, with leaves dropping. Snowfall is allowed, but it should not accumulate much. In general, I prefer dry falls to wet ones, so try to minimize rain, but you can list wetter places too if you want. So, what places have - on average - the longest period in which the weather meets these criteria?
Check out Metlakatla, AK. Almost like a year round fall. The temperature ranges don't match exactly with what you outlined, and the rainfall amount is ridiculous, but it is still the first thing that jumped to mind. These are responsible for the vibrant ambers, reds and yellows of autumn. The chemicals responsible are types of flavonoids, carotenoids and anthocyanins.
