The prediction comes from 14 years of fall color records at this spot, checked against what observers on the ground saw. Where state foliage spotters report peak (New York, Pennsylvania, Wisconsin and Missouri), it has landed inside our ±5-day window about two years in three. An unusual summer or autumn can still move it further. Explore fall color around Piatt County and across Illinois.
