Chicago's Fall Foliage Threatened by Recent Drought

Experts predict less vibrant autumn colors due to dry conditions in August and September.

Chicago's moderate drought in August and September has accelerated leaf color changes, leading to earlier and potentially duller fall foliage.
Rainfall at O'Hare Airport was about half the 30-year average, receiving only 3.92 inches compared to the usual 7.44 inches for the period.
Urban areas in Chicago are particularly affected, with trees showing pronounced browning and early leaf drop due to heat absorption by surfaces.
Optimal fall colors require adequate moisture and cool nights, conditions which have been disrupted by the recent dry spell.
Meteorologists suggest that while recent rain may help, it is unlikely to fully reverse the drought's impact on fall foliage.
