The extreme heat designation is characterized by the National Weather Service as days where the heat index reaches above 125 degrees.

A recent study from First Street Foundation found that most of the counties in Indiana will continue to see high heat day increases, with the southern portion of the state seeing the largest increase in what are called extreme heat days. Martin, Harrison and Clark counties are expected to see the greatest increase.

This phenomenon is not limited in Indiana. An Extreme Heat Belt is expected to stretch from the northern border of Texas and Louisiana, through Iowa, Illinois and Indiana.
