Climate change is altering the very color of fall foliage

Human decisions about forest management are also having a devastating effect.

Fall foliage in the Philly area may suffer from the unusually warm and wet weather

The next several days should be ideal for morning walks in the Philly region with temperatures in the low 60s, a solid 10 degrees above long-term normals.

Fall foliage could be ruined by summer that won’t quit

The warm, wet conditions persisting into the early days of autumn could dim Pennsylvania’s chances for a great fall foliage season in the coming weeks.

Penn State: Warm, wet autumn could mute, delay foliage in Pennsylvania

Experts with Penn State's College of Agricultural Science say weather conditions will need to be cooler and drier in the next few weeks for Pennsylvania's forests to see the vibrant colors of fall foliage.

Fantastic fall foliage could be ruined by summer that won’t quit

The warm, wet conditions persisting into the early days of autumn could dim Pennsylvania's chances for a great fall foliage season in the coming weeks.

Warm, wet autumn could mute and delay foliage display in Pennsylvania

Because of the warm, wet summer, trees in Pennsylvania are mostly in great shape. But for the state’s forests to exhibit their most vibrant colors, conditions need to be cooler and drier in the next few weeks, according to a Penn State expert.

Penn State professors predict foliage coloration for fall 2020

Marc Abrams has lived in State College for 33 years. Abrams, a Penn State professor of forest ecology and physiology, said he has been called on annually for several years about whether the fall leaves would be as beautiful as years prior, with people picking his brain for his expertise of the foliage.

Fall foliage outlooks are bullish for colors — and leaf-peeping crowds

A refreshing splash of normality is about to enter this disorienting autumn of Zoom classes, quarantines, and masked professors. The annual fall foliage show already is creeping across the woods, and early indications are that it will be more than a pleasant distraction.

Northeast Drought Could Threaten Penn State Fall Foliage Display

Penn State’s fall foliage display might look a little less vibrant and a lot crisper this season. According to university experts, little rain in the long-term weather forecast could threaten Pennsylvania’s usually dynamic fall foliage.

Dry conditions affecting harvest sizes, foliage

The fall foliage and fruit and corn harvests are getting hammered by a lack of rain.
