For being an F5 and hitting a capital city, this tornado seems to be under loved. I did a good amount of research on this day back in college, but mainly on a secondary tornado that hit Manhattan, KS the same day.
The one thing I specifically remember is the old tall indian tale saying that because of Burnett's Mound, Topeka would be shielded from tornadoes from the southwest. Not the case, as the tornado actually hit Burnett's Mound before making a bee line directly into downtown Topeka.
It seems as if people heeded the warning, as fatalities were minimal. I even believe the National Weather Service (weather bureau) in Topeka at Billard Airport took a hit by the tornado.
I remember the infamous quote from Bill Kurtis, who was a reporter for WIBW-TV saying "For God's Sake, Take Cover" as the F5 missed the station to the south.
