Baking cookies aside, this heat is about to subside.
A cold front is going to swing across the entire Gulf Coast on Monday night and into Tuesday, which will drop temperatures by five to ten degrees. The same front will also drop the humidity, too. This combination won't make it cool by any stretch, but it's relief from dangerous weather, nonetheless.
After that, the South will have to go back to baking cookies the old fashioned way - in an oven.
