    It's been another brutal Arkansas summer. Temps continue to run above average and the humidity continues to be oppressive.

    Heat is deadly. From 2000-2009 it was the number 1 weather related killer with an average of 162 fatalities a year. When you combine the humidity it gets even more dangerous. The heat index is a tool we used to give advance notice of when it gets dangerous outside.

    There are ways our bodies try to cool us off. Evaporative cooling through sweating in the main way. Ed shows us how it works with a garden hose and fan in this edition of Weather 101.
