I wouldn't be surprised if we see a rather marked change in this graphic in ten days as we get into a significant round of chilled air starting tonight. Fall color is starting to appear in a few spots around town but is more prevalent across the Poconos, the "T" in Central Pennsylvania, and points north.
According to the PA Department of Tourism 70% of the trees have changed color along the Northern Tier of the state, with 30% color change having taken place across the Poconos and along Blue Mountain in Central Pennsylvania. With a cool to at times chilly week ahead, I would expect those numbers to jump a fair bit in the next week to ten days, with north of I-80 likely peaking in Fall color within the week and the Poconos, Blue Mountain, and Hawk Mountain likely peaking next weekend.
Locally, we're still about three weeks away from peak color, which is pretty much in line for the Delaware Valley historically.
