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 is building an interactive MOS archive to support local research and makes it available for others to use as well.
Archive Status: NAM and GFS MOS back to 3 May 2007. The archive updates in real-time as products are received from the NWS.
csv.php?station=KAMW&ts=2009-01-10%2012:00 (all data 10 days) csv.php?station=KAMW&runtime=2009-01-10%2012:00&model=GFS (explicit)
Note: MOS variables are stored as their raw encodings in the text product, except wdr (wind direction) which is multiplied by 10 for its true value.
We will probably back fill the archive based on how much interest this application generates, so please let us know if you find this page useful.
