This diagram shows the highest wind supply in Missouri are found in the extreme northwestern section of the map. Class 3 areas are concentrated from St. Joseph north to the Iowa perimeter. Particular areas in the Class 3 areas could have higher wind power class values at 80-m than shown on the 50-m chart because of possible high wind shear. Given the advances in technology, a number of regions in the Class 3 areas may be suitable for utility-scale wind development.

A renewable energy source, airstream is classified according to wind power classes, which are created from usual wind speeds. The classes vary from Class 1 (the least) to Class 7 (the top). Ordinarily, at 150 feet , windpower Class 4 or greater is useful for making wind power with substantial turbines. Class 4 and higher are deemed excellent resources. Individual locations in the Class 3 areas might have superior wind power classes at 80 meters than shown on the 50 meter map because of potential elevated wind shear. Because of the improvements in machinery, some locations in the Class 3 regions may proper for large scale wind power company development.
