The IEM maintains an archive of the National High and Low Temperature product. This product is disseminated over NOAAPort in an XML format and called XTEUS. This data presentation is powered by an IEM Web Service. The IEM archive begins on 30 June 2008, but the data quality prior to 2011 has been a bit suspect due to issues with the raw text product and other things that makes life fun.
