Lots of moist air arriving straight from the Gulf of Mexico. Skies clearing momentarily. I stop at a motel to watch the Weather Channel. They say a cold front is arriving from NW, and the center of the depression is right over Iowa. After Des Moines.
Air is hot, very hot, very humid, sticky.
Iowa is quite flat and has LOTS of farms. Farms, farms, farms. I am driving to the northwest of Iowa, hoping for the storms to show up. The air is no more sticky and moist, and I even get goose-bumps. I stop and chat with a local farmer.
