DISCUSSION: As we look back to this past Tuesday, there was quite an impressive severe weather break across several states across the Central Plains as well as points to the east. As discussed in the text excerpt below (courtesy of KNWA and FOX24 Meteorologist Dan Skoff), there were quite favorable conditions in place for much of the day which allowed for the occurrence of severe thunderstorms capable of generating tornadoes.
"Prepare to have your mind blown! THIS IS TRULY INCREDIBLE! Yesterday the environment was ripe for tornadoes across a good portion of the central US and ONE supercell thunderstorm in particular utilized those ingredients and became a prolific tornado producer.
The deadly supercell first initially formed right over Northwest Arkansas in northern Benton co, crossed through nearly 5 states (almost to the Ohio border) and lasted for nearly 12 hours. You will notice once the storm split in NE Barry county... the right mover took over and it made a b-line right for #Perryville producing a strong to violent tornado. The storm merged with a few other small storms as the monster absorbed them easily in southern IL and then just kept on truckin' through Indiana. Talk about a long track tornadic supercell thunderstorm."
As is referenced in the text above, the concept of right-movers involves the reality of in-storm dynamics allowing for storms to either split over the course of some period of time. This storm splitting occurs due to a complex collection of processes which are discussed in far more detail within the following link!
