Fall colors are showing up weeks ahead of schedule this year across the Northeast, and forecasters say the primary reason is due to the weather.

"Leaves started early this fall to make the change from their normal green to yellows and oranges across the Northeast and Ohio Valley," AccuWeather Senior Meteorologist Paul Pastelok said.

"Over recent years, the change [has been] more pronounced in late September," Pastelok explained.

The main culprit has been a stretch of dry weather dating back to August, which has stressed certain trees and caused them to slow the supply of food and water to the leaves.
