Dangerous temperatures will persist across parts of the U.S. through July, and in some areas, there's an unexpected contributor.

With that title comes an increased dew point thanks to a process called evapotranspiration , or corn sweat. The crop naturally pulls water from the ground through its roots, uses it for essential physiologic functions and releases moisture through its leaves as water vapor.

It is “corn sweat” season. The biggest U.S. crop does influence our weather here in Michigan and across the Midwest. All plants drink up moisture from the soil and then breathe some of it out in a process called transpiration. The transpiration puts water vapor in the air and increases the humidity.

While the humidity is low in Central Ohio today, you're probably seeing stories on your news feed about corn sweat impacting the Midwest.
