(Blacksburg)- The leaves may not be quite as colorful this fall. A forestry professor at Virginia Tech says the recent lack of rain is heavily affecting the usual vibrant colors on trees. Some trees have already browned and dropped leaves. He’s advising a trip to the Blue Ridge Parkway, where elevation changes may bring a better chance for color. Most of the Commonwealth was listed in moderate drought conditions in the latest U.S. Drought Monitor report.
