Another things that seem strange is Kansas and Missouri all time record low temps are -40F which both occurred on February 13, 1905 in Lebanon, Kansas and Warsaw, Missouri. That actually is colder than the all time record lows of Illinois(-36F), Indiana(-36F)and Ohio(-39F). Iowa is -47F which is colder but those 4 states especially Iowa and Illinois tend to get more brutal winds and colder temperatures more often than Kansas and Missouri.
