In the weather section of the Washington Post, on June 15, 2011, there was an interesting write up of the deadly tornadoes in 2011 and how problems remain, even with the advent of radar and better warning systems since 1925. See the article : Shocking: Tornado death rates in 2011 return to pre-1925 levels.
I just located the original NOAA briefing materials, titled Spring 2011: A season of U.S. Climate and Weather Extremes (June 15, 2011; 14 pages). I highly recommend reading the full report.
