snip-Much of the Midwest, including Franklin County, is under a heat advisory this week and one phenomenon that may be contributing to how humid it is outside is corn and the water it sweats off while growing.
While corn sweat, also called evapotranspiration, doesn't cause temperatures to skyrocket, the moisture certainly contributes to hotter days. The common Midwest saying is, "it's not the heat that gets you, but the humidity" could apply to corn sweat as well.
snip-"A single acre sweats 3,000 to 4,000 gallons of water every day. If you do the math, that means upwards of 14 billion gallons of water is sweated into the atmosphere by corn every day."
