Experts are predicting robust fall foliage this autumn in PA and NY

Ryan Reed, an environmental education specialist in the Bureau of Forestry, says the groundwork has really been laid for fall color. Because of a wet summer, he says the leaves are loaded with sugars, which should boost the vibrancy of fall colors.

Optimum fall colors are produced by the normal, seasonal cool down into October of nighttime temperatures in the 30s followed by sunny days.

Warmer temperatures prolong the period of green in the leaves and reduce the period of peak fall colors.
