The peak of fall foliage has already passed from northern New York through northern New England, but for the big cities of the I-95 corridor, leaves are still turning.

The peak of fall foliage has already passed from northern New York through northern New England. Multiple frosts gripped the region during late September and early October, helping the peak of color to arrive on schedule.

"A frost helps to bring out the color. What happens is that the chlorophyll - which causes the green color of leaves - starts to break down. This basically exposes the other pigments like red and orange," Dr. Marc Abrams, a professor of Forest Ecology and Physiology at Penn State, said. Abrams began observing how weather conditions affect fall foliage 25 years ago.

As of the middle of October, bright, peak fall leaf color is on display across eastern Maine, southern New Hampshire, western portions of Maine and Connecticut, central parts of New York state and in the Appalachian mountains of Pennsylvania.

Boston, New York City and Philadelphia are showing moderate fall colors with more color in the northern and western suburbs. The temperature has only dropped below 40 degrees once so far this season in Boston, New York City and Philadelphia on Oct. 13, 2012. The typical peak in fall foliage for these I-95 cities is late in October.
