Corn is making the heat worse

Temperatures and humidity levels are rising across the Heartland, and one crop is exacerbating the heat. Corn is playing a role in these sweltering conditions. Here's what you need to know.

The TemperatureRadar shows heat building across the Midwest this week, with highs in the 90s. However, humidity levels are rising due to the cultivation of a popular crop in this region. Evapotranspiration is the process by which corn exhales water vapor through its leaves. This process exacerbates humidity in agricultural areas during the summer.

This time of year is when evapotranspiration is at its peak, meaning this heat wave will be ferocious as humidity levels rise. Feels-like temperatures will run 10-15 degrees higher than the actual temperatures this week in cities like Omaha, Neb., Kansas City, Indianapolis and St. Louis.

Keep an eye on the TemperaturRadar, and check the humidity levels and feels like temperatures on the Weather & Radar app.
