the Midwest is experiencing a heat wave and it may feel worse in some areas because of something called corn sweat meteorologist Chris Michaels is here to explain why areas with more corn crops are a bit more humid Chris exactly yeah so if you were to go into the Corn Belt of the United States you would have seen D points over the past few days in the upper 70s and lower 80s that's pretty much top of the charts and a lot of it has to do with something that's called evapo transpiration although folks out there more commonly call it corn sweat so what's happening is that the corn is releasing moisture one acre can release about 3 to 4,000 gallons of moisture into the air and this happens as temperatures rise kind of like how we sweat so it contributes to higher due points that in tandem with the high heat was leading to the heat index of 105 to 115 Chicago O'Hare reported a heat index at 115 yesterday now heat advisories continue for parts of the Corn Belt like Indiana Ohio but you see that advancing farther to the east we don't necessarily have a heat advisory but we do have some high heat in the forecast if one were to be issued we'd see the heat index between 104 to 109 thankfully not up to 115 and thankfully doesn't look like a whole lot of corn sweat going on here in Central North Carolina no sorry I'm from the Midwest and when I first saw this I Googled it going is this really a thing but then I was like you're a meteorologist trust your local meteorologist and it is but I wonder can other crops do the same thing like color greens maybe I mean you know and you you can drive past a far F early in the morning and sometimes you can see that thin layer of fog which is kind of an indication of maybe some of that sweating or evaporation that's uh going on but yeah Chris when when I pitched the story this morning there were a few faces on the team's call going is this guy serious I was interested I go I'm from the Cornell I'm interested talk about it thanks Chris got it
