Daryl Herzmann at the Iowa Environmental Mesonet has made some major updates to the archives at the IEM recently regarding NWS issued warnings back through 1986. Also included in the update are 5 minute, 1 km radar images back through 1995. Anyone interested in GIS applications will be excited to know that shapefiles of warning boxes have been built back through 1986 as well, an impressive accomplishment. You can find plenty of other archived data at the IEM as well.
