Greg and Dan talk with Chief Meteorologist Chuck Collins, about the intense heat dome currently affecting the Peoria region.

Chuck explains that this heat dome is responsible for the extreme temperatures and oppressive conditions across much of the Midwest. While the peak of this particular heat wave may only last a few days, the high humidity and sweltering “steam bath” effect is expected to persist well into the coming weeks, making for an uncomfortable stretch of summer weather.

A major factor contributing to the ongoing humidity in Central Illinois is the abundance of cornfields surrounding the Peoria area. As Chuck explains, each acre of corn can release up to 4,000 gallons of water into the atmosphere through a natural process called evapotranspiration. This moisture adds significantly to the region’s already humid air—especially during July, when corn reaches its peak growth. This unique agricultural effect means that even after the worst of the heat dome passes, residents can expect continued muggy conditions thanks to the combination of atmospheric patterns and local environmental influences.
