Many of the coordinates in this article are for impossible locations. As an example, Picher/Neosho on 10 May is given as 36°91′N 94°58′W, but there aren't 91 minutes of arc in a degree. There are many more of these problems in the list and they show up in this report on broken coordinates. I'd hazard a guess that what is meant is a decimal point, so that example should be at 36.91°N instead of 36°91′N, but if so the reader has to wonder why whoever wrote the article didn't enter the coordinates in that way, instead specifying them with arcminutes. As a result it's no good going through and changing them all to decimal points to fit in a valid range; the original sources need to be consulted, perhaps with the aid of a map, to work out what should be given as the coordinates. 79.64.227.29 ( talk) 22:09, 15 May 2009 (UTC) reply
