According to a map from Smoky Mountains National Park, the Chicago area has already begun to see patches of fall colors, and will have partial foliage coverage by next week.
The week of Oct. 11 trees around Chicago will likely be nearing their peak of foliage, the map shows, while the fall colors hit their height the week of Oct. 18.
By Oct. 25 into November, most of the foliage will be past its peak throughout Illinois, according to the map.
Though temperatures are beginning to drop around Chicago, the leaves changing colors is caused by the decreased levels of sunlight during the day, according to the Illinois Department of Natural Resources.
The spring and summer sunlight fills the leaves with chlorophyll, which gives them the green appearance, IDNR says. As hours of sunlight drop, the plants receive less chlorophyll, causing them to appear tones of orange, red and yellow.
For those able to venture around Illinois to experience the foliage, IOT also released a list of road trip itineraries. Here are some highlights:
