hey guys what is corn sweat yeah if you're not from the Midwest you may not have heard of that it's actually moisture from inside the leaves of corn stocks and on the outside evaporating into the atmosphere in a process called evapor transpiration now this can make it feel a lot hotter out there because it raises the dup points and in fact the D points can go 5 to 10 degrees higher so they're in the upper 70s today in Iowa and Illinois that's comparable to Florida in fact it's more than Florida the forecast shows this getting hotter especially during the afternoons under the sunshine and then some cold fronts try and bring some drier air but did you know that this can put 49 to 56 billion gallons of water into the atmosphere each day
