Crop maps (IMAGE) Penn State Caption The graphic shows the overlay of precipitation and temperature color coded to represent the best locations for corn in 2016 and in a climate scenario representative of 2064 if emissions are not curtailed. The darkest shade of purple is where temperature and precipitation align to provide the best weather for corn -- for example, from northern Ohio all the way west through parts of Indiana, Michigan, Illinois and Iowa, among other states. In the projected 2060 panel, the best combination of precipitation and temperature become narrower and move north from current conditions.
