KokomoWX Posted May 22, 2012 Share Posted May 22, 2012 US Tornadoes has put out a map showing tornadoes by county for 1950 to 2011. It has 16 for Howard County. My records only show 14. July 9, 1951 May 28, 1955 March 6, 1961 April 11, 1965 April 3, 1974 June 15, 1976 July 7, 1977 April 23, 1978 April 14, 1987 July 17, 1996 June 11, 1998 April 20, 2004 July 26, 2005 October 25, 2010 I cannot find the data to support the claim of 16. Any thoughts/help? Edit: never mind, I forgot that two of the dates has two confirmed tornadoes. Link to comment Share on other sites More sharing options...
mappy Posted May 22, 2012 Share Posted May 22, 2012 Hi, I'm actually the map maker.... Let me check and get back to you Link to comment Share on other sites More sharing options...
mappy Posted May 22, 2012 Share Posted May 22, 2012 We get our data from SPC - but you can view it on tornadohistoryproject http://www.tornadohistoryproject.com/custom/1361736/table THP confirms the 16 count Link to comment Share on other sites More sharing options...

I was just being forgetful this morning. 1961 and 2004 had two tornadoes on the same day. Thanks for the great work. Link to comment Share on other sites More sharing options...
mappy Posted May 22, 2012 Share Posted May 22, 2012 Thanks. I was just being forgetful this morning. 1961 and 2004 had two tornadoes on the same day. Thanks for the great work. No problem! There have been errors, but it's within the data itself, SPC wasn't very good with checking their lat/long coordinates, so I have had to use County and State FIPS code to determine counts per county. While I cannot double check each and every county, I try to check a random few with THP, who uses the same data. Thanks for visiting the site!

A-L-E-K Posted May 22, 2012 Share Posted May 22, 2012 anyone have an explanation for the differences between Illinois and Missouri? Link to comment Share on other sites More sharing options...
Hoosier Posted May 22, 2012 Share Posted May 22, 2012 anyone have an explanation for the differences between Illinois and Missouri? I can think of a few possible reasons. 1) visibility/terrain differences...lots of trees and hilly areas in Missouri which could impact the ability to see or even tornado formation itself in some cases, 2) population differences...no doubt Illinois has rural areas but Missouri is more rural, 3) something more meteorological? Perhaps more outbreaks tend to occur in the Plains and then "skip" over Missouri at night and refire farther east the next day. Link to comment Share on other sites More sharing options...
Geos Posted May 22, 2012 Share Posted May 22, 2012 Cool website! With regards to Alek's question, I'm thinking there was more people in Illinois to observe tornadoes than Missouri. Edit: And the points Hoosier pointed out^ Link to comment Share on other sites More sharing options...
Hoosier Posted May 22, 2012 Share Posted May 22, 2012 For the Indiana folks, I just noticed that IND added a lot of tornado climo stuff (for the entire state) to their tornado page: http://www.crh.noaa.gov/ind/?n=torn Link to comment Share on other sites More sharing options...

wxman_ind Posted May 24, 2012 Share Posted May 24, 2012 FYI: The Tornado Fatalities chart is actually US fatalities and not Indiana fatalities. Thanks for catching that. I will try and get it fixed soon. You guys discovered my work in progress before I was ready to announce it. :-) Link to comment Share on other sites More sharing options...

I have no data to back it up, but Missouri would suffer the same the same issues of say Iowa where convection fires over the sloped terrain of the Plains and diurnally weakens beyond the Missouri Valley. And that makes sense when you consider convective mode as well. Initiation and shortly thereafter would favor supercells, with the tendency to grow upscale into a linear system or multicell cluster with eastward extent, reducing the tornado potential.
