Meteorological synopsis

April 6

On April 6, a strong storm system in the southern section of the Rocky Mountains moved east to the central and southern Great Plains region during the afternoon and to the mid and lower Mississippi River Valley during the overnight hours. The system was accompanied by strong winds in the middle and high levels of the atmosphere along with cold upper air temperatures. With these elements coming together with moisture moving north from the Gulf of Mexico, it resulted in conditions favorable for severe weather. A moderate risk of severe weather was issued for that day by the Storm Prediction Center as a result across eastern Colorado and neighboring parts of Texas, Kansas, Oklahoma, and Nebraska. With a dryline extending from central Nebraska to northwestern Texas, thunderstorms began developing along the dryline across south and central Kansas by 2:45 PM CDT (1945 UTC). These storms would form into supercells and move into eastern Kansas by 3:35 PM CDT (2035 UTC).

Storm chasers and civilians in the region reported multiple funnel clouds and several touchdowns, neither of which caused damage. A large, intense tornado later caused severe damage in and around several towns in east-central Kansas. Many houses were destroyed or flattened from what was at times a double tornado with two well-defined vortices. Numerous injuries were reported in the latter of these areas.
