A corny dewpoint forecast

117This summer has seen some very high dew points, at times into the middle 70’s making things feel very sticky. What if corn had something to do with our moisture content…well it does! During this summer’s wet growing season, a large amount of moisture evaporated off the leaves of cornfields through the midwest. Combining southerly gulf flow with this evapotranspiration, this is why we see so much humidity during our summers.

Now that the growing season is coming to a close, crops aren’t shedding as much water into the atmosphere. Despite southerly flow, this is one cause of our recently drier air.
