The National Weather Service operates a number of operational weather prediction models. These models produce a gridded forecast that is then processed thru a series of equations (Model Output Statistics) to produce a site specific forecast. You can find out more about MOS on the NWS's website. The IEM maintains an interactive MOS archive to support local research and makes it available for others to use as well.
