According to a National Weather Sevice report at 5:25 PM, a funnel cloud was spotted at 37.07N 94.70W in Riverton, Kansas.
Mike Griffith, a meteorologist with the weather service station, said a supercell thunderstorm intensified rapidly west of Joplin in Cherokee County, Kan. “It was clear that a hook echo was forming and that a large tornado was developing,” he said. “We picked up the debris ball here on our radar. When you see that, it signifies that major damage is going on.” Griffith said the tornado that struck Joplin was a right-turning tornado, the same type of tornado that struck Picher, Okla., and Newton County on May 10, 2008.

The tornado initially touched down just east of the Kansas state boundary near the end of 32nd Street between 5:35 and 5:41 p.m. CDT (2235 and 2241 UTC) and tracked just north of due east. Surveys remain incomplete there so it is possible it may have started in Kansas and crossed the state line into Missouri. (Wikipedia)
